    Description: Comparative genomic analyses have revealed that genes may arise from ancestrally nongenic sequence. However, the origin and spread of these de novo genes within populations remain obscure. We identified 142 segregating and 106 fixed testis-expressed de novo genes in a population sample of Drosophila melanogaster. These genes appear to derive primarily from ancestral intergenic, unexpressed open reading frames, with natural selection playing a significant role in their spread. These results reveal a heretofore unappreciated dynamism of gene content.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4391638/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4391638/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Zhao, Li -- Saelao, Perot -- Jones, Corbin D -- Begun, David J -- GM084056/GM/NIGMS NIH HHS/ -- R01 GM084056/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2014 Feb 14;343(6172):769-72. doi: 10.1126/science.1248286.

    Description: Biological oscillations are observed at many levels of cellular organization. In the social amoeba Dictyostelium discoideum, starvation-triggered multicellular development is organized by periodic cyclic adenosine 3',5'-monophosphate (cAMP) waves, which provide both chemoattractant gradients and developmental signals. We report that GtaC, a GATA transcription factor, exhibits rapid nucleocytoplasmic shuttling in response to cAMP waves. This behavior requires coordinated action of a nuclear localization signal and reversible G protein (heterotrimeric guanine nucleotide-binding protein)-coupled receptor-mediated phosphorylation. Although both are required for developmental gene expression, receptor occupancy promotes nuclear exit of GtaC, which leads to a transient burst of transcription at each cAMP cycle. We demonstrate that this biological circuit filters out high-frequency signals and counts those admitted, thereby enabling cells to modulate gene expression according to the dynamic pattern of the external stimuli.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4061987/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4061987/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Cai, Huaqing -- Katoh-Kurasawa, Mariko -- Muramoto, Tetsuya -- Santhanam, Balaji -- Long, Yu -- Li, Lei -- Ueda, Masahiro -- Iglesias, Pablo A -- Shaulsky, Gad -- Devreotes, Peter N -- GM 28007/GM/NIGMS NIH HHS/ -- GM 34933/GM/NIGMS NIH HHS/ -- HD 039691/HD/NICHD NIH HHS/ -- P01 HD039691/HD/NICHD NIH HHS/ -- R01 GM028007/GM/NIGMS NIH HHS/ -- R01 GM034933/GM/NIGMS NIH HHS/ -- R37 GM028007/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2014 Mar 21;343(6177):1249531. doi: 10.1126/science.1249531.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Cell Biology, School of Medicine, Johns Hopkins University, Baltimore, MD 21205, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/24653039" target="_blank"〉PubMed〈/a〉

    Description: Motor neurons, which relay neural commands to drive skeletal muscle movements, encompass types ranging from "slow" to "fast," whose biophysical properties govern the timing, gradation, and amplitude of muscle force. Here we identify the noncanonical Notch ligand Delta-like homolog 1 (Dlk1) as a determinant of motor neuron functional diversification. Dlk1, expressed by ~30% of motor neurons, is necessary and sufficient to promote a fast biophysical signature in the mouse and chick. Dlk1 suppresses Notch signaling and activates expression of the K(+) channel subunit Kcng4 to modulate delayed-rectifier currents. Dlk1 inactivation comprehensively shifts motor neurons toward slow biophysical and transcriptome signatures, while abolishing peak force outputs. Our findings provide insights into the development of motor neuron functional diversity and its contribution to the execution of movements.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Muller, Daniel -- Cherukuri, Pitchaiah -- Henningfeld, Kristine -- Poh, Chor Hoon -- Wittler, Lars -- Grote, Phillip -- Schluter, Oliver -- Schmidt, Jennifer -- Laborda, Jorge -- Bauer, Steven R -- Brownstone, Robert M -- Marquardt, Till -- R01 HD042013/HD/NICHD NIH HHS/ -- Canadian Institutes of Health Research/Canada -- New York, N.Y. -- Science. 2014 Mar 14;343(6176):1264-6. doi: 10.1126/science.1246448.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Developmental Neurobiology Laboratory, European Neuroscience Institute (ENI-G), Grisebachstrasse 5, 37077 Gottingen, Germany.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/24626931" target="_blank"〉PubMed〈/a〉

    Description: The assembly of artificial cells capable of executing synthetic DNA programs has been an important goal for basic research and biotechnology. We assembled two-dimensional DNA compartments fabricated in silicon as artificial cells capable of metabolism, programmable protein synthesis, and communication. Metabolism is maintained by continuous diffusion of nutrients and products through a thin capillary, connecting protein synthesis in the DNA compartment with the environment. We programmed protein expression cycles, autoregulated protein levels, and a signaling expression gradient, equivalent to a morphogen, in an array of interconnected compartments at the scale of an embryo. Gene expression in the DNA compartment reveals a rich, dynamic system that is controlled by geometry, offering a means for studying biological networks outside a living cell.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Karzbrun, Eyal -- Tayar, Alexandra M -- Noireaux, Vincent -- Bar-Ziv, Roy H -- New York, N.Y. -- Science. 2014 Aug 15;345(6198):829-32. doi: 10.1126/science.1255550.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Materials and Interfaces, Weizmann Institute of Science, Rehovot 76100, Israel. ; Department of Physics, University of Minnesota, Minneapolis, MN 55455, USA. ; Department of Materials and Interfaces, Weizmann Institute of Science, Rehovot 76100, Israel. roy.bar-ziv@weizmann.ac.il.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/25124443" target="_blank"〉PubMed〈/a〉

    Description: T cells that mediate autoimmune diseases such as rheumatoid arthritis (RA) are difficult to characterize because they are likely to be deleted or inactivated in the thymus if the self antigens they recognize are ubiquitously expressed. One way to obtain and analyze these autoimmune T cells is to alter T cell receptor (TCR) signaling in developing T cells to change their sensitivity to thymic negative selection, thereby allowing their thymic production. From mice thus engineered to generate T cells mediating autoimmune arthritis, we isolated arthritogenic TCRs and characterized the self antigens they recognized. One of them was the ubiquitously expressed 60S ribosomal protein L23a (RPL23A), with which T cells and autoantibodies from RA patients reacted. This strategy may improve our understanding of the underlying drivers of autoimmunity.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ito, Yoshinaga -- Hashimoto, Motomu -- Hirota, Keiji -- Ohkura, Naganari -- Morikawa, Hiromasa -- Nishikawa, Hiroyoshi -- Tanaka, Atsushi -- Furu, Moritoshi -- Ito, Hiromu -- Fujii, Takao -- Nomura, Takashi -- Yamazaki, Sayuri -- Morita, Akimichi -- Vignali, Dario A A -- Kappler, John W -- Matsuda, Shuichi -- Mimori, Tsuneyo -- Sakaguchi, Noriko -- Sakaguchi, Shimon -- R01 DK089125/DK/NIDDK NIH HHS/ -- New York, N.Y. -- Science. 2014 Oct 17;346(6207):363-8. doi: 10.1126/science.1259077.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Experimental Pathology, Institute for Frontier Medical Sciences, Kyoto University, Kyoto 606-8507, Japan. ; Department of Experimental Pathology, Institute for Frontier Medical Sciences, Kyoto University, Kyoto 606-8507, Japan.

    Description: Sheep (Ovis aries) are a major source of meat, milk, and fiber in the form of wool and represent a distinct class of animals that have a specialized digestive organ, the rumen, that carries out the initial digestion of plant material. We have developed and analyzed a high-quality reference sheep genome and transcriptomes from 40 different tissues. We identified highly expressed genes encoding keratin cross-linking proteins associated with rumen evolution. We also identified genes involved in lipid metabolism that had been amplified and/or had altered tissue expression patterns. This may be in response to changes in the barrier lipids of the skin, an interaction between lipid metabolism and wool synthesis, and an increased role of volatile fatty acids in ruminants compared with nonruminant animals.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4157056/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4157056/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Jiang, Yu -- Xie, Min -- Chen, Wenbin -- Talbot, Richard -- Maddox, Jillian F -- Faraut, Thomas -- Wu, Chunhua -- Muzny, Donna M -- Li, Yuxiang -- Zhang, Wenguang -- Stanton, Jo-Ann -- Brauning, Rudiger -- Barris, Wesley C -- Hourlier, Thibaut -- Aken, Bronwen L -- Searle, Stephen M J -- Adelson, David L -- Bian, Chao -- Cam, Graham R -- Chen, Yulin -- Cheng, Shifeng -- DeSilva, Udaya -- Dixen, Karen -- Dong, Yang -- Fan, Guangyi -- Franklin, Ian R -- Fu, Shaoyin -- Fuentes-Utrilla, Pablo -- Guan, Rui -- Highland, Margaret A -- Holder, Michael E -- Huang, Guodong -- Ingham, Aaron B -- Jhangiani, Shalini N -- Kalra, Divya -- Kovar, Christie L -- Lee, Sandra L -- Liu, Weiqing -- Liu, Xin -- Lu, Changxin -- Lv, Tian -- Mathew, Tittu -- McWilliam, Sean -- Menzies, Moira -- Pan, Shengkai -- Robelin, David -- Servin, Bertrand -- Townley, David -- Wang, Wenliang -- Wei, Bin -- White, Stephen N -- Yang, Xinhua -- Ye, Chen -- Yue, Yaojing -- Zeng, Peng -- Zhou, Qing -- Hansen, Jacob B -- Kristiansen, Karsten -- Gibbs, Richard A -- Flicek, Paul -- Warkup, Christopher C -- Jones, Huw E -- Oddy, V Hutton -- Nicholas, Frank W -- McEwan, John C -- Kijas, James W -- Wang, Jun -- Worley, Kim C -- Archibald, Alan L -- Cockett, Noelle -- Xu, Xun -- Wang, Wen -- Dalrymple, Brian P -- 095908/Wellcome Trust/United Kingdom -- 098051/Wellcome Trust/United Kingdom -- BB/1025360/1/Biotechnology and Biological Sciences Research Council/United Kingdom -- BB/I025328/1/Biotechnology and Biological Sciences Research Council/United Kingdom -- BB/I025360/1/Biotechnology and Biological Sciences Research Council/United Kingdom -- BB/I025506/1/Biotechnology and Biological Sciences Research Council/United Kingdom -- U54 HG003273/HG/NHGRI NIH HHS/ -- WT095908/Wellcome Trust/United Kingdom -- WT098051/Wellcome Trust/United Kingdom -- New York, N.Y. -- Science. 2014 Jun 6;344(6188):1168-73. doi: 10.1126/science.1252806.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉State Key Laboratory of Genetic Resources and Evolution, Kunming Institute of Zoology, Chinese Academy of Sciences, Kunming 650223, China.

    Description: Little is known about the genetic basis of convergent traits that originate repeatedly over broad taxonomic scales. The myogenic electric organ has evolved six times in fishes to produce electric fields used in communication, navigation, predation, or defense. We have examined the genomic basis of the convergent anatomical and physiological origins of these organs by assembling the genome of the electric eel (Electrophorus electricus) and sequencing electric organ and skeletal muscle transcriptomes from three lineages that have independently evolved electric organs. Our results indicate that, despite millions of years of evolution and large differences in the morphology of electric organ cells, independent lineages have leveraged similar transcription factors and developmental and cellular pathways in the evolution of electric organs.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gallant, Jason R -- Traeger, Lindsay L -- Volkening, Jeremy D -- Moffett, Howell -- Chen, Po-Hao -- Novina, Carl D -- Phillips, George N Jr -- Anand, Rene -- Wells, Gregg B -- Pinch, Matthew -- Guth, Robert -- Unguez, Graciela A -- Albert, James S -- Zakon, Harold H -- Samanta, Manoj P -- Sussman, Michael R -- 1SC1GM092297-01A1/GM/NIGMS NIH HHS/ -- R01 GM084879/GM/NIGMS NIH HHS/ -- R01 GM088670/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2014 Jun 27;344(6191):1522-5. doi: 10.1126/science.1254432.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Zoology, Michigan State University, East Lansing, MI 48824, USA.

    Description: Long noncoding RNAs (lncRNAs) play important roles in diverse biological processes; however, few have been identified that regulate immune cell differentiation and function. Here, we identified lnc-DC, which was exclusively expressed in human conventional dendritic cells (DCs). Knockdown of lnc-DC impaired DC differentiation from human monocytes in vitro and from mouse bone marrow cells in vivo and reduced capacity of DCs to stimulate T cell activation. lnc-DC mediated these effects by activating the transcription factor STAT3 (signal transducer and activator of transcription 3). lnc-DC bound directly to STAT3 in the cytoplasm, which promoted STAT3 phosphorylation on tyrosine-705 by preventing STAT3 binding to and dephosphorylation by SHP1. Our work identifies a lncRNA that regulates DC differentiation and also broadens the known mechanisms of lncRNA action.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wang, Pin -- Xue, Yiquan -- Han, Yanmei -- Lin, Li -- Wu, Cong -- Xu, Sheng -- Jiang, Zhengping -- Xu, Junfang -- Liu, Qiuyan -- Cao, Xuetao -- New York, N.Y. -- Science. 2014 Apr 18;344(6181):310-3. doi: 10.1126/science.1251456.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉National Key Laboratory of Medical Immunology and Institute of Immunology, Second Military Medical University, Shanghai 200433, China.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/24744378" target="_blank"〉PubMed〈/a〉

    Description: Reef corals are highly sensitive to heat, yet populations resistant to climate change have recently been identified. To determine the mechanisms of temperature tolerance, we reciprocally transplanted corals between reef sites experiencing distinct temperature regimes and tested subsequent physiological and gene expression profiles. Local acclimatization and fixed effects, such as adaptation, contributed about equally to heat tolerance and are reflected in patterns of gene expression. In less than 2 years, acclimatization achieves the same heat tolerance that we would expect from strong natural selection over many generations for these long-lived organisms. Our results show both short-term acclimatory and longer-term adaptive acquisition of climate resistance. Adding these adaptive abilities to ecosystem models is likely to slow predictions of demise for coral reef ecosystems.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Palumbi, Stephen R -- Barshis, Daniel J -- Traylor-Knowles, Nikki -- Bay, Rachael A -- New York, N.Y. -- Science. 2014 May 23;344(6186):895-8. doi: 10.1126/science.1251336.

    Description: Lymphocytes face major metabolic challenges upon activation. They must meet the bioenergetic and biosynthetic demands of increased cell proliferation and also adapt to changing environmental conditions, in which nutrients and oxygen may be limiting. An emerging theme in immunology is that metabolic reprogramming and lymphocyte activation are intricately linked. However, why T cells adopt specific metabolic programs and the impact that these programs have on T cell function and, ultimately, immunological outcome remain unclear. Research on tumor cell metabolism has provided valuable insight into metabolic pathways important for cell proliferation and the influence of metabolites themselves on signal transduction and epigenetic programming. In this Review, we highlight emerging concepts regarding metabolic reprogramming in proliferating cells and discuss their potential impact on T cell fate and function.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4486656/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4486656/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Pearce, Erika L -- Poffenberger, Maya C -- Chang, Chih-Hao -- Jones, Russell G -- AI091965/AI/NIAID NIH HHS/ -- CA158823/CA/NCI NIH HHS/ -- MOP-93799/Canadian Institutes of Health Research/Canada -- R01 AI091965/AI/NIAID NIH HHS/ -- R01 CA181125/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 2013 Oct 11;342(6155):1242454. doi: 10.1126/science.1242454.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Pathology and Immunology, Washington University School of Medicine, St. Louis, MO 63110, USA. erikapearce@path.wustl.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/24115444" target="_blank"〉PubMed〈/a〉

    Description: Jet-lag symptoms arise from temporal misalignment between the internal circadian clock and external solar time. We found that circadian rhythms of behavior (locomotor activity), clock gene expression, and body temperature immediately reentrained to phase-shifted light-dark cycles in mice lacking vasopressin receptors V1a and V1b (V1a(-/-)V1b(-/-)). Nevertheless, the behavior of V1a(-/-)V1b(-/-) mice was still coupled to the internal clock, which oscillated normally under standard conditions. Experiments with suprachiasmatic nucleus (SCN) slices in culture suggested that interneuronal communication mediated by V1a and V1b confers on the SCN an intrinsic resistance to external perturbation. Pharmacological blockade of V1a and V1b in the SCN of wild-type mice resulted in accelerated recovery from jet lag, which highlights the potential of vasopressin signaling as a therapeutic target for management of circadian rhythm misalignment, such as jet lag and shift work.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Yamaguchi, Yoshiaki -- Suzuki, Toru -- Mizoro, Yasutaka -- Kori, Hiroshi -- Okada, Kazuki -- Chen, Yulin -- Fustin, Jean-Michel -- Yamazaki, Fumiyoshi -- Mizuguchi, Naoki -- Zhang, Jing -- Dong, Xin -- Tsujimoto, Gozoh -- Okuno, Yasushi -- Doi, Masao -- Okamura, Hitoshi -- New York, N.Y. -- Science. 2013 Oct 4;342(6154):85-90. doi: 10.1126/science.1238599.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Systems Biology, Graduate School of Pharmaceutical Sciences, Kyoto University, Sakyo-ku, Kyoto 606-8501, Japan.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/24092737" target="_blank"〉PubMed〈/a〉

    Description: Transcription regulation occurs frequently through promoter-associated pausing of RNA polymerase II (Pol II). We developed a precision nuclear run-on and sequencing (PRO-seq) assay to map the genome-wide distribution of transcriptionally engaged Pol II at base pair resolution. Pol II accumulates immediately downstream of promoters, at intron-exon junctions that are efficiently used for splicing, and over 3' polyadenylation sites. Focused analyses of promoters reveal that pausing is not fixed relative to initiation sites, nor is it specified directly by the position of a particular core promoter element or the first nucleosome. Core promoter elements function beyond initiation, and when optimally positioned they act collectively to dictate the position and strength of pausing. This "complex interaction" model was tested with insertional mutagenesis of the Drosophila Hsp70 core promoter.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3974810/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3974810/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kwak, Hojoong -- Fuda, Nicholas J -- Core, Leighton J -- Lis, John T -- GM25232/GM/NIGMS NIH HHS/ -- HG004845/HG/NHGRI NIH HHS/ -- R01 GM025232/GM/NIGMS NIH HHS/ -- R01 HG004845/HG/NHGRI NIH HHS/ -- R37 GM025232/GM/NIGMS NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2013 Feb 22;339(6122):950-3. doi: 10.1126/science.1229386.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Molecular Biology and Genetics, Cornell University, Ithaca, NY 14853, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/23430654" target="_blank"〉PubMed〈/a〉

    Description: How an individual's longevity is affected by the opposite sex is still largely unclear. In the nematode Caenorhabditis elegans, the presence of males accelerated aging and shortened the life span of individuals of the opposite sex (hermaphrodites), including long-lived or sterile hermaphrodites. The male-induced demise could occur without mating and required only exposure of hermaphrodites to medium in which males were once present. Such communication through pheromones or other diffusible substances points to a nonindividual autonomous mode of aging regulation. The male-induced demise also occurred in other species of nematodes, suggesting an evolutionary conserved process whereby males may induce the disposal of the opposite sex to save resources for the next generation or to prevent competition from other males.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4126796/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4126796/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Maures, Travis J -- Booth, Lauren N -- Benayoun, Berenice A -- Izrayelit, Yevgeniy -- Schroeder, Frank C -- Brunet, Anne -- DP1 AG044848/AG/NIA NIH HHS/ -- DP1AG044848/AG/NIA NIH HHS/ -- F32AG37254/AG/NIA NIH HHS/ -- R01 AG031198/AG/NIA NIH HHS/ -- R01 GM088290/GM/NIGMS NIH HHS/ -- R01AG031198/AG/NIA NIH HHS/ -- R01GM088290/GM/NIGMS NIH HHS/ -- T32 GM008500/GM/NIGMS NIH HHS/ -- T32 HG000044/HG/NHGRI NIH HHS/ -- T32GM008500/GM/NIGMS NIH HHS/ -- T32HG000044/HG/NHGRI NIH HHS/ -- New York, N.Y. -- Science. 2014 Jan 31;343(6170):541-4. doi: 10.1126/science.1244160.

    Description: The resolution of type 2 diabetes after Roux-en-Y gastric bypass (RYGB) attests to the important role of the gastrointestinal tract in glucose homeostasis. Previous studies in RYGB-treated rats have shown that the Roux limb displays hyperplasia and hypertrophy. Here, we report that the Roux limb of RYGB-treated rats exhibits reprogramming of intestinal glucose metabolism to meet its increased bioenergetic demands; glucose transporter-1 is up-regulated, basolateral glucose uptake is enhanced, aerobic glycolysis is augmented, and glucose is directed toward metabolic pathways that support tissue growth. We show that reprogramming of intestinal glucose metabolism is triggered by the exposure of the Roux limb to undigested nutrients. We demonstrate by positron emission tomography-computed tomography scanning and biodistribution analysis using 2-deoxy-2-[18F]fluoro-D-glucose that reprogramming of intestinal glucose metabolism renders the intestine a major tissue for glucose disposal, contributing to the improvement in glycemic control after RYGB.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4068965/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4068965/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Saeidi, Nima -- Meoli, Luca -- Nestoridi, Eirini -- Gupta, Nitin K -- Kvas, Stephanie -- Kucharczyk, John -- Bonab, Ali A -- Fischman, Alan J -- Yarmush, Martin L -- Stylopoulos, Nicholas -- DK089503/DK/NIDDK NIH HHS/ -- F32 DK095558/DK/NIDDK NIH HHS/ -- F32DK095558/DK/NIDDK NIH HHS/ -- P50 GM021700/GM/NIGMS NIH HHS/ -- T32DK007191/DK/NIDDK NIH HHS/ -- New York, N.Y. -- Science. 2013 Jul 26;341(6144):406-10. doi: 10.1126/science.1235103.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Center for Basic and Translational Obesity Research, Division of Endocrinology, Boston Children's Hospital, Harvard Medical School, Boston, MA 02115, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/23888041" target="_blank"〉PubMed〈/a〉

    Description: Circadian clocks have evolved to regulate physiologic and behavioral rhythms in anticipation of changes in the environment. Although the molecular clock is present in innate immune cells, its role in monocyte homeostasis remains unknown. Here, we report that Ly6C(hi) inflammatory monocytes exhibit diurnal variation, which controls their trafficking to sites of inflammation. This cyclic pattern of trafficking confers protection against Listeria monocytogenes and is regulated by the repressive activity of the circadian gene Bmal1. Accordingly, myeloid cell-specific deletion of Bmal1 induces expression of monocyte-attracting chemokines and disrupts rhythmic cycling of Ly6C(hi) monocytes, predisposing mice to development of pathologies associated with acute and chronic inflammation. These findings have unveiled a critical role for BMAL1 in controlling the diurnal rhythms in Ly6C(hi) monocyte numbers.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3836670/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3836670/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Nguyen, Khoa D -- Fentress, Sarah J -- Qiu, Yifu -- Yun, Karen -- Cox, Jeffery S -- Chawla, Ajay -- DK094641/DK/NIDDK NIH HHS/ -- DP1 AR064158/AR/NIAMS NIH HHS/ -- DP1AR064158/AR/NIAMS NIH HHS/ -- HL076746/HL/NHLBI NIH HHS/ -- P01AI063302/AI/NIAID NIH HHS/ -- R01 DK094641/DK/NIDDK NIH HHS/ -- R01 HL076746/HL/NHLBI NIH HHS/ -- T32 AI007334/AI/NIAID NIH HHS/ -- T32AI007334/AI/NIAID NIH HHS/ -- New York, N.Y. -- Science. 2013 Sep 27;341(6153):1483-8. doi: 10.1126/science.1240636.

    Description: Studies of area patterning of the neocortex have focused on primary areas, concluding that the primary visual area, V1, is specified by transcription factors (TFs) expressed by progenitors. Mechanisms that determine higher-order visual areas (V(HO)) and distinguish them from V1 are unknown. We demonstrated a requirement for thalamocortical axon (TCA) input by genetically deleting geniculocortical TCAs and showed that they drive differentiation of patterned gene expression that distinguishes V1 and V(HO). Our findings suggest a multistage process for area patterning: TFs expressed by progenitors specify an occipital visual cortical field that differentiates into V1 and V(HO); this latter phase requires geniculocortical TCA input to the nascent V1 that determines genetic distinctions between V1 and V(HO) for all layers and ultimately determines their area-specific functional properties.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3851411/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3851411/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Chou, Shen-Ju -- Babot, Zoila -- Leingartner, Axel -- Studer, Michele -- Nakagawa, Yasushi -- O'Leary, Dennis D M -- MH086147/MH/NIMH NIH HHS/ -- R01 MH086147/MH/NIMH NIH HHS/ -- R01 NS031558/NS/NINDS NIH HHS/ -- R01 NS31558/NS/NINDS NIH HHS/ -- R37 NS031558/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 2013 Jun 7;340(6137):1239-42. doi: 10.1126/science.1232806.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Molecular Neurobiology Laboratory, The Salk Institute for Biological Studies, La Jolla, CA, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/23744949" target="_blank"〉PubMed〈/a〉

    Description: The gut microbiota influences both local and systemic inflammation. Inflammation contributes to development, progression, and treatment of cancer, but it remains unclear whether commensal bacteria affect inflammation in the sterile tumor microenvironment. Here, we show that disruption of the microbiota impairs the response of subcutaneous tumors to CpG-oligonucleotide immunotherapy and platinum chemotherapy. In antibiotics-treated or germ-free mice, tumor-infiltrating myeloid-derived cells responded poorly to therapy, resulting in lower cytokine production and tumor necrosis after CpG-oligonucleotide treatment and deficient production of reactive oxygen species and cytotoxicity after chemotherapy. Thus, optimal responses to cancer therapy require an intact commensal microbiota that mediates its effects by modulating myeloid-derived cell functions in the tumor microenvironment. These findings underscore the importance of the microbiota in the outcome of disease treatment.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Iida, Noriho -- Dzutsev, Amiran -- Stewart, C Andrew -- Smith, Loretta -- Bouladoux, Nicolas -- Weingarten, Rebecca A -- Molina, Daniel A -- Salcedo, Rosalba -- Back, Timothy -- Cramer, Sarah -- Dai, Ren-Ming -- Kiu, Hiu -- Cardone, Marco -- Naik, Shruti -- Patri, Anil K -- Wang, Ena -- Marincola, Francesco M -- Frank, Karen M -- Belkaid, Yasmine -- Trinchieri, Giorgio -- Goldszmid, Romina S -- Intramural NIH HHS/ -- New York, N.Y. -- Science. 2013 Nov 22;342(6161):967-70. doi: 10.1126/science.1240527.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Cancer and Inflammation Program, National Cancer Institute, Frederick, MD 21702, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/24264989" target="_blank"〉PubMed〈/a〉

    Description: Influenza A virus (IAV) infection leads to variable and imperfectly understood pathogenicity. We report that segment 3 of the virus contains a second open reading frame ("X-ORF"), accessed via ribosomal frameshifting. The frameshift product, termed PA-X, comprises the endonuclease domain of the viral PA protein with a C-terminal domain encoded by the X-ORF and functions to repress cellular gene expression. PA-X also modulates IAV virulence in a mouse infection model, acting to decrease pathogenicity. Loss of PA-X expression leads to changes in the kinetics of the global host response, which notably includes increases in inflammatory, apoptotic, and T lymphocyte-signaling pathways. Thus, we have identified a previously unknown IAV protein that modulates the host response to infection, a finding with important implications for understanding IAV pathogenesis.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3552242/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3552242/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Jagger, B W -- Wise, H M -- Kash, J C -- Walters, K-A -- Wills, N M -- Xiao, Y-L -- Dunfee, R L -- Schwartzman, L M -- Ozinsky, A -- Bell, G L -- Dalton, R M -- Lo, A -- Efstathiou, S -- Atkins, J F -- Firth, A E -- Taubenberger, J K -- Digard, P -- 073126/Wellcome Trust/United Kingdom -- 088789/Wellcome Trust/United Kingdom -- G0700815/Medical Research Council/United Kingdom -- G0700815(82260)/Medical Research Council/United Kingdom -- G9800943/Medical Research Council/United Kingdom -- MR/J002232/1/Medical Research Council/United Kingdom -- Biotechnology and Biological Sciences Research Council/United Kingdom -- Intramural NIH HHS/ -- New York, N.Y. -- Science. 2012 Jul 13;337(6091):199-204. doi: 10.1126/science.1222213.

    Description: Most species' sex chromosomes are derived from ancient autosomes and show few signatures of their origins. We studied the sex chromosomes of Drosophila miranda, where a neo-Y chromosome originated only approximately 1 million years ago. Whole-genome and transcriptome analysis reveals massive degeneration of the neo-Y, that male-beneficial genes on the neo-Y are more likely to undergo accelerated protein evolution, and that neo-Y genes evolve biased expression toward male-specific tissues--the shrinking gene content of the neo-Y becomes masculinized. In contrast, although older X chromosomes show a paucity of genes expressed in male tissues, neo-X genes highly expressed in male-specific tissues undergo increased rates of protein evolution if haploid in males. Thus, the response to sex-specific selection can shift at different stages of X differentiation, resulting in masculinization or demasculinization of the X-chromosomal gene content.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4107656/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4107656/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Zhou, Qi -- Bachtrog, Doris -- R01 GM076007/GM/NIGMS NIH HHS/ -- R01 GM093182/GM/NIGMS NIH HHS/ -- R01GM076007/GM/NIGMS NIH HHS/ -- R01GM093182/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2012 Jul 20;337(6092):341-5. doi: 10.1126/science.1225385.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Integrative Biology, University of California Berkeley, Berkeley, CA 94720, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/22822149" target="_blank"〉PubMed〈/a〉

    Description: De-ubiquitinating enzyme BAP1 is mutated in a hereditary cancer syndrome with increased risk of mesothelioma and uveal melanoma. Somatic BAP1 mutations occur in various malignancies. We show that mouse Bap1 gene deletion is lethal during embryogenesis, but systemic or hematopoietic-restricted deletion in adults recapitulates features of human myelodysplastic syndrome (MDS). Knockin mice expressing BAP1 with a 3xFlag tag revealed that BAP1 interacts with host cell factor-1 (HCF-1), O-linked N-acetylglucosamine transferase (OGT), and the polycomb group proteins ASXL1 and ASXL2 in vivo. OGT and HCF-1 levels were decreased by Bap1 deletion, indicating a critical role for BAP1 in stabilizing these epigenetic regulators. Human ASXL1 is mutated frequently in chronic myelomonocytic leukemia (CMML) so an ASXL/BAP1 complex may suppress CMML. A BAP1 catalytic mutation found in a MDS patient implies that BAP1 loss of function has similar consequences in mice and humans.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Dey, Anwesha -- Seshasayee, Dhaya -- Noubade, Rajkumar -- French, Dorothy M -- Liu, Jinfeng -- Chaurushiya, Mira S -- Kirkpatrick, Donald S -- Pham, Victoria C -- Lill, Jennie R -- Bakalarski, Corey E -- Wu, Jiansheng -- Phu, Lilian -- Katavolos, Paula -- LaFave, Lindsay M -- Abdel-Wahab, Omar -- Modrusan, Zora -- Seshagiri, Somasekar -- Dong, Ken -- Lin, Zhonghua -- Balazs, Mercedesz -- Suriben, Rowena -- Newton, Kim -- Hymowitz, Sarah -- Garcia-Manero, Guillermo -- Martin, Flavius -- Levine, Ross L -- Dixit, Vishva M -- R01 CA173636/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 2012 Sep 21;337(6101):1541-6.

    Description: Although coagulation factors play a role in host defense for "living fossils" such as horseshoe crabs, the role of the coagulation system in immunity in higher organisms remains unclear. We modeled the interface of human species C adenovirus (HAdv) interaction with coagulation factor X (FX) and introduced a mutation that abrogated formation of the HAdv-FX complex. In vivo genome-wide transcriptional profiling revealed that FX-binding-ablated virus failed to activate a distinct network of nuclear factor kappaB-dependent early-response genes that are activated by HAdv-FX complex downstream of TLR4/MyD88/TRIF/TRAF6 signaling. Our study implicates host factor "decoration" of the virus as a mechanism to trigger an innate immune sensor that responds to a misplacement of coagulation FX from the blood into intracellular macrophage compartments upon virus entry into the cell.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4762479/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4762479/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Doronin, Konstantin -- Flatt, Justin W -- Di Paolo, Nelson C -- Khare, Reeti -- Kalyuzhniy, Oleksandr -- Acchione, Mauro -- Sumida, John P -- Ohto, Umeharu -- Shimizu, Toshiyuki -- Akashi-Takamura, Sachiko -- Miyake, Kensuke -- MacDonald, James W -- Bammler, Theo K -- Beyer, Richard P -- Farin, Frederico M -- Stewart, Phoebe L -- Shayakhmetov, Dmitry M -- AI065429/AI/NIAID NIH HHS/ -- CA141439/CA/NCI NIH HHS/ -- P30ES07033/ES/NIEHS NIH HHS/ -- R01 AI065429/AI/NIAID NIH HHS/ -- R01 CA141439/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 2012 Nov 9;338(6108):795-8. doi: 10.1126/science.1226625.

    Description: To better understand the response to mitochondrial dysfunction, we examined the mechanism by which ATFS-1 (activating transcription factor associated with stress-1) senses mitochondrial stress and communicates with the nucleus during the mitochondrial unfolded protein response (UPR(mt)) in Caenorhabditis elegans. We found that the key point of regulation is the mitochondrial import efficiency of ATFS-1. In addition to a nuclear localization sequence, ATFS-1 has an N-terminal mitochondrial targeting sequence that is essential for UPR(mt) repression. Normally, ATFS-1 is imported into mitochondria and degraded. However, during mitochondrial stress, we found that import efficiency was reduced, allowing a percentage of ATFS-1 to accumulate in the cytosol and traffic to the nucleus. Our results show that cells monitor mitochondrial import efficiency via ATFS-1 to coordinate the level of mitochondrial dysfunction with the protective transcriptional response.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3518298/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3518298/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Nargund, Amrita M -- Pellegrino, Mark W -- Fiorese, Christopher J -- Baker, Brooke M -- Haynes, Cole M -- R01 AG040061/AG/NIA NIH HHS/ -- R01AG040061/AG/NIA NIH HHS/ -- New York, N.Y. -- Science. 2012 Aug 3;337(6094):587-90. doi: 10.1126/science.1223560.

    Description: Little is known about the molecular basis of differences in behavior among individuals. Here we report consistent novelty-seeking behavior, across different contexts, among honey bees in their tendency to scout for food sources and nest sites, and we reveal some of the molecular underpinnings of this behavior relative to foragers that do not scout. Food scouts showed extensive differences in brain gene expression relative to other foragers, including differences related to catecholamine, glutamate, and gamma-aminobutyric acid signaling. Octopamine and glutamate treatments increased the likelihood of scouting, whereas dopamine antagonist treatment decreased it. These findings demonstrate intriguing similarities in human and insect novelty seeking and suggest that this trait, which presumably evolved independently in these two lineages, may be subserved by conserved molecular components.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Liang, Zhengzheng S -- Nguyen, Trang -- Mattila, Heather R -- Rodriguez-Zas, Sandra L -- Seeley, Thomas D -- Robinson, Gene E -- 1DP1OD006416/OD/NIH HHS/ -- R21 DA027548/DA/NIDA NIH HHS/ -- New York, N.Y. -- Science. 2012 Mar 9;335(6073):1225-8. doi: 10.1126/science.1213962.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Neuroscience Program, University of Illinois at Urbana-Champaign, Urbana, IL, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/22403390" target="_blank"〉PubMed〈/a〉

    Description: Withdrawal of nutrients triggers an exit from the cell division cycle, the induction of autophagy, and eventually the activation of cell death pathways. The relation, if any, among these events is not well characterized. We found that starved mouse embryonic fibroblasts lacking the essential autophagy gene product Atg7 failed to undergo cell cycle arrest. Independent of its E1-like enzymatic activity, Atg7 could bind to the tumor suppressor p53 to regulate the transcription of the gene encoding the cell cycle inhibitor p21(CDKN1A). With prolonged metabolic stress, the absence of Atg7 resulted in augmented DNA damage with increased p53-dependent apoptosis. Inhibition of the DNA damage response by deletion of the protein kinase Chk2 partially rescued postnatal lethality in Atg7(-/-) mice. Thus, when nutrients are limited, Atg7 regulates p53-dependent cell cycle and cell death pathways.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4721513/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4721513/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lee, In Hye -- Kawai, Yoshichika -- Fergusson, Maria M -- Rovira, Ilsa I -- Bishop, Alexander J R -- Motoyama, Noboru -- Cao, Liu -- Finkel, Toren -- Z01 HL005012-12/Intramural NIH HHS/ -- New York, N.Y. -- Science. 2012 Apr 13;336(6078):225-8. doi: 10.1126/science.1218395.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Center for Molecular Medicine, National Heart, Lung, and Blood Institute, Bethesda, MD 20892, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/22499945" target="_blank"〉PubMed〈/a〉

    Description: Tolerant self-antigen-specific CD8 T cells fail to proliferate in response to antigen, thereby preventing autoimmune disease. By using an in vivo mouse model, we show that tolerant T cells proliferate and become functional under lymphopenic conditions, even in a tolerogenic environment. However, T cell rescue is only transient, with tolerance reimposed upon lymphorepletion even in the absence of tolerogen (self-antigen), challenging the prevailing paradigm that continuous antigen exposure is critical to maintain tolerance. Genome-wide messenger RNA and microRNA profiling revealed that tolerant T cells have a tolerance-specific gene profile that can be temporarily overridden under lymphopenic conditions but is inevitably reimposed, which suggests epigenetic regulation. These insights into the regulatory mechanisms that maintain or break self-tolerance may lead to new strategies for the treatment of cancer and autoimmunity.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3754789/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3754789/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Schietinger, Andrea -- Delrow, Jeffrey J -- Basom, Ryan S -- Blattman, Joseph N -- Greenberg, Philip D -- K01 CA117985/CA/NCI NIH HHS/ -- P30 CA015704/CA/NCI NIH HHS/ -- P30 CA015704-35/CA/NCI NIH HHS/ -- P30 DK 56465/DK/NIDDK NIH HHS/ -- P30 DK056465/DK/NIDDK NIH HHS/ -- R01 CA033084/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 2012 Feb 10;335(6069):723-7. doi: 10.1126/science.1214277.

    Description: Long-term memory (LTM) depends on the synthesis of new proteins. Using a temperature-sensitive ribosome-inactivating toxin to acutely inhibit protein synthesis, we screened individual neurons making new proteins after olfactory associative conditioning in Drosophila. Surprisingly, LTM was impaired after inhibiting protein synthesis in two dorsal-anterior-lateral (DAL) neurons but not in the mushroom body (MB), which is considered the adult learning and memory center. Using a photoconvertible fluorescent protein KAEDE to report de novo protein synthesis, we have directly visualized cyclic adenosine monophosphate (cAMP) response element-binding protein (CREB)-dependent transcriptional activation of calcium/calmodulin-dependent protein kinase II and period genes in the DAL neurons after spaced but not massed training. Memory retention was impaired by blocking neural output in DAL during retrieval but not during acquisition or consolidation. These findings suggest an extra-MB memory circuit in Drosophila: LTM consolidation (MB to DAL), storage (DAL), and retrieval (DAL to MB).〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Chen, Chun-Chao -- Wu, Jie-Kai -- Lin, Hsuan-Wen -- Pai, Tsung-Pin -- Fu, Tsai-Feng -- Wu, Chia-Lin -- Tully, Tim -- Chiang, Ann-Shyn -- New York, N.Y. -- Science. 2012 Feb 10;335(6069):678-85. doi: 10.1126/science.1212735.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Institute of Biotechnology and Department of Life Science, National Tsing Hua University, Hsinchu 30013, Taiwan.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/22323813" target="_blank"〉PubMed〈/a〉

    Description: Color markings among felid species display both a remarkable diversity and a common underlying periodicity. A similar range of patterns in domestic cats suggests a conserved mechanism whose appearance can be altered by selection. We identified the gene responsible for tabby pattern variation in domestic cats as Transmembrane aminopeptidase Q (Taqpep), which encodes a membrane-bound metalloprotease. Analyzing 31 other felid species, we identified Taqpep as the cause of the rare king cheetah phenotype, in which spots coalesce into blotches and stripes. Histologic, genomic expression, and transgenic mouse studies indicate that paracrine expression of Endothelin3 (Edn3) coordinates localized color differences. We propose a two-stage model in which Taqpep helps to establish a periodic pre-pattern during skin development that is later implemented by differential expression of Edn3.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3709578/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3709578/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kaelin, Christopher B -- Xu, Xiao -- Hong, Lewis Z -- David, Victor A -- McGowan, Kelly A -- Schmidt-Kuntzel, Anne -- Roelke, Melody E -- Pino, Javier -- Pontius, Joan -- Cooper, Gregory M -- Manuel, Hermogenes -- Swanson, William F -- Marker, Laurie -- Harper, Cindy K -- van Dyk, Ann -- Yue, Bisong -- Mullikin, James C -- Warren, Wesley C -- Eizirik, Eduardo -- Kos, Lidia -- O'Brien, Stephen J -- Barsh, Gregory S -- Menotti-Raymond, Marilyn -- N01-CO-12400/CO/NCI NIH HHS/ -- U54 HG003079/HG/NHGRI NIH HHS/ -- Intramural NIH HHS/ -- New York, N.Y. -- Science. 2012 Sep 21;337(6101):1536-41.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉HudsonAlpha Institute for Biotechnology, Huntsville, AL 35806, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/22997338" target="_blank"〉PubMed〈/a〉

    Description: Death is a vital developmental cell fate. In Caenorhabditis elegans, programmed death of the linker cell, which leads gonadal elongation, proceeds independently of caspases and apoptotic effectors. To identify genes promoting linker-cell death, we performed a genome-wide RNA interference screen. We show that linker-cell death requires the gene pqn-41, encoding an endogenous polyglutamine-repeat protein. pqn-41 functions cell-autonomously and is expressed at the onset of linker-cell death. pqn-41 expression is controlled by the mitogen-activated protein kinase kinase SEK-1, which functions in parallel to the zinc-finger protein LIN-29 to promote cellular demise. Linker-cell death is morphologically similar to cell death associated with normal vertebrate development and polyglutamine-induced neurodegeneration. Our results may therefore provide molecular inroads to understanding nonapoptotic cell death in metazoan development and disease.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3858082/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3858082/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Blum, Elyse S -- Abraham, Mary C -- Yoshimura, Satoshi -- Lu, Yun -- Shaham, Shai -- CA09673/CA/NCI NIH HHS/ -- R01 HD042680/HD/NICHD NIH HHS/ -- R01HD042680/HD/NICHD NIH HHS/ -- New York, N.Y. -- Science. 2012 Feb 24;335(6071):970-3. doi: 10.1126/science.1215156.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratory of Developmental Genetics, The Rockefeller University, 1230 York Avenue, New York, NY 10065, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/22363008" target="_blank"〉PubMed〈/a〉

    Description: Unraveling the intricate interactions between Trypanosoma brucei, the protozoan parasite causing African trypanosomiasis, and the tsetse (Glossina) vector remains a challenge. Metacyclic trypanosomes, which inhabit the tsetse salivary glands, transmit the disease and are produced through a complex differentiation and unknown program. By overexpressing a single RNA-binding protein, TbRBP6, in cultured noninfectious trypanosomes, we recapitulated the developmental stages that have been observed in tsetse, including the generation of infective metacyclic forms expressing the variant surface glycoprotein. Thus, events leading to acquisition of infectivity in the insect vector are now accessible to laboratory investigation, providing an opening for new intervention strategies.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3664091/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3664091/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kolev, Nikolay G -- Ramey-Butler, Kiantra -- Cross, George A M -- Ullu, Elisabetta -- Tschudi, Christian -- AI021729/AI/NIAID NIH HHS/ -- AI028798/AI/NIAID NIH HHS/ -- AI043594/AI/NIAID NIH HHS/ -- AI076879/AI/NIAID NIH HHS/ -- R01 AI021729/AI/NIAID NIH HHS/ -- R01 AI043594/AI/NIAID NIH HHS/ -- R21 AI076879/AI/NIAID NIH HHS/ -- R37 AI028798/AI/NIAID NIH HHS/ -- New York, N.Y. -- Science. 2012 Dec 7;338(6112):1352-3. doi: 10.1126/science.1229641.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Epidemiology of Microbial Diseases, Yale School of Public Health, New Haven, CT 06536, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/23224556" target="_blank"〉PubMed〈/a〉

    Description: Brain-derived neurotrophic factor (BDNF) is a key positive regulator of neural plasticity, promoting, for example, the actions of stimulant drugs of abuse such as cocaine. We discovered a surprising opposite role for BDNF in countering responses to chronic morphine exposure. The suppression of BDNF in the ventral tegmental area (VTA) enhanced the ability of morphine to increase dopamine (DA) neuron excitability and promote reward. In contrast, optical stimulation of VTA DA terminals in nucleus accumbens (NAc) completely reversed the suppressive effect of BDNF on morphine reward. Furthermore, we identified numerous genes in the NAc, a major target region of VTA DA neurons, whose regulation by BDNF in the context of chronic morphine exposure mediated this counteractive function. These findings provide insight into the molecular basis of morphine-induced neuroadaptations in the brain's reward circuitry.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3547365/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3547365/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Koo, Ja Wook -- Mazei-Robison, Michelle S -- Chaudhury, Dipesh -- Juarez, Barbara -- LaPlant, Quincey -- Ferguson, Deveroux -- Feng, Jian -- Sun, Haosheng -- Scobie, Kimberly N -- Damez-Werno, Diane -- Crumiller, Marshall -- Ohnishi, Yoshinori N -- Ohnishi, Yoko H -- Mouzon, Ezekiell -- Dietz, David M -- Lobo, Mary Kay -- Neve, Rachael L -- Russo, Scott J -- Han, Ming-Hu -- Nestler, Eric J -- K99 MH094405/MH/NIMH NIH HHS/ -- P01 DA008227/DA/NIDA NIH HHS/ -- R01 DA014133/DA/NIDA NIH HHS/ -- R01 MH092306/MH/NIMH NIH HHS/ -- T32 MH087004/MH/NIMH NIH HHS/ -- New York, N.Y. -- Science. 2012 Oct 5;338(6103):124-8. doi: 10.1126/science.1222265.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Fishberg Department of Neuroscience and Friedman Brain Institute, Mount Sinai School of Medicine, New York, NY 10029, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/23042896" target="_blank"〉PubMed〈/a〉

    Description: Burmese pythons display a marked increase in heart mass after a large meal. We investigated the molecular mechanisms of this physiological heart growth with the goal of applying this knowledge to the mammalian heart. We found that heart growth in pythons is characterized by myocyte hypertrophy in the absence of cell proliferation and by activation of physiological signal transduction pathways. Despite high levels of circulating lipids, the postprandial python heart does not accumulate triglycerides or fatty acids. Instead, there is robust activation of pathways of fatty acid transport and oxidation combined with increased expression and activity of superoxide dismutase, a cardioprotective enzyme. We also identified a combination of fatty acids in python plasma that promotes physiological heart growth when injected into either pythons or mice.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3383835/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3383835/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Riquelme, Cecilia A -- Magida, Jason A -- Harrison, Brooke C -- Wall, Christopher E -- Marr, Thomas G -- Secor, Stephen M -- Leinwand, Leslie A -- 5K01AR055676/AR/NIAMS NIH HHS/ -- HL050560/HL/NHLBI NIH HHS/ -- K01 AR055676/AR/NIAMS NIH HHS/ -- New York, N.Y. -- Science. 2011 Oct 28;334(6055):528-31. doi: 10.1126/science.1210558.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Molecular, Cellular, and Developmental Biology, University of Colorado, Boulder, CO 80309, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/22034436" target="_blank"〉PubMed〈/a〉

    Description: Synaptic plasticity is the experience-dependent change in connectivity between neurons that is believed to underlie learning and memory. Here, we discuss the cellular and molecular processes that are altered when a neuron responds to external stimuli, and how these alterations lead to an increase or decrease in synaptic connectivity. Modification of synaptic components and changes in gene expression are necessary for many forms of plasticity. We focus on excitatory neurons in the mammalian hippocampus, one of the best-studied model systems of learning-related plasticity.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3286636/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3286636/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ho, Victoria M -- Lee, Ji-Ann -- Martin, Kelsey C -- R01 MH077022/MH/NIMH NIH HHS/ -- R01 MH077022-05/MH/NIMH NIH HHS/ -- R01 NS045324/NS/NINDS NIH HHS/ -- R01 NS045324-11/NS/NINDS NIH HHS/ -- R21 MH069645/MH/NIMH NIH HHS/ -- R21 MH069645-02/MH/NIMH NIH HHS/ -- T32 GM008042/GM/NIGMS NIH HHS/ -- T32 MH073526/MH/NIMH NIH HHS/ -- New York, N.Y. -- Science. 2011 Nov 4;334(6056):623-8. doi: 10.1126/science.1209236.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Interdepartmental Program in Neurosciences, University of California-Los Angeles (UCLA), BSRB 390B, 615 Charles E.

    Description: Disruption of the circadian clock exacerbates metabolic diseases, including obesity and diabetes. We show that histone deacetylase 3 (HDAC3) recruitment to the genome displays a circadian rhythm in mouse liver. Histone acetylation is inversely related to HDAC3 binding, and this rhythm is lost when HDAC3 is absent. Although amounts of HDAC3 are constant, its genomic recruitment in liver corresponds to the expression pattern of the circadian nuclear receptor Rev-erbalpha. Rev-erbalpha colocalizes with HDAC3 near genes regulating lipid metabolism, and deletion of HDAC3 or Rev-erbalpha in mouse liver causes hepatic steatosis. Thus, genomic recruitment of HDAC3 by Rev-erbalpha directs a circadian rhythm of histone acetylation and gene expression required for normal hepatic lipid homeostasis.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3389392/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3389392/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Feng, Dan -- Liu, Tao -- Sun, Zheng -- Bugge, Anne -- Mullican, Shannon E -- Alenghat, Theresa -- Liu, X Shirley -- Lazar, Mitchell A -- DK19525/DK/NIDDK NIH HHS/ -- DK43806/DK/NIDDK NIH HHS/ -- DK45586/DK/NIDDK NIH HHS/ -- DK49210/DK/NIDDK NIH HHS/ -- HG4069/HG/NHGRI NIH HHS/ -- P30 DK019525/DK/NIDDK NIH HHS/ -- R01 DK045586/DK/NIDDK NIH HHS/ -- R37 DK043806/DK/NIDDK NIH HHS/ -- R37 DK043806-20/DK/NIDDK NIH HHS/ -- RC1 DK086239/DK/NIDDK NIH HHS/ -- RC1DK08623/DK/NIDDK NIH HHS/ -- New York, N.Y. -- Science. 2011 Mar 11;331(6022):1315-9. doi: 10.1126/science.1198125.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Division of Endocrinology, Diabetes, and Metabolism, Department of Medicine, University of Pennsylvania School of Medicine, Philadelphia, PA 19104, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/21393543" target="_blank"〉PubMed〈/a〉

    Description: The gain, loss, and modification of gene regulatory elements may underlie a substantial proportion of phenotypic changes on animal lineages. To investigate the gain of regulatory elements throughout vertebrate evolution, we identified genome-wide sets of putative regulatory regions for five vertebrates, including humans. These putative regulatory regions are conserved nonexonic elements (CNEEs), which are evolutionarily conserved yet do not overlap any coding or noncoding mature transcript. We then inferred the branch on which each CNEE came under selective constraint. Our analysis identified three extended periods in the evolution of gene regulatory elements. Early vertebrate evolution was characterized by regulatory gains near transcription factors and developmental genes, but this trend was replaced by innovations near extracellular signaling genes, and then innovations near posttranslational protein modifiers.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3511857/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3511857/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lowe, Craig B -- Kellis, Manolis -- Siepel, Adam -- Raney, Brian J -- Clamp, Michele -- Salama, Sofie R -- Kingsley, David M -- Lindblad-Toh, Kerstin -- Haussler, David -- 1U01-HG004695/HG/NHGRI NIH HHS/ -- 5P41-HG002371/HG/NHGRI NIH HHS/ -- P41 HG002371/HG/NHGRI NIH HHS/ -- P50 HG002568/HG/NHGRI NIH HHS/ -- P50-HG02568/HG/NHGRI NIH HHS/ -- R01 HG004037/HG/NHGRI NIH HHS/ -- R01-HG004037/HG/NHGRI NIH HHS/ -- U01 HG004695/HG/NHGRI NIH HHS/ -- U54 HG003067/HG/NHGRI NIH HHS/ -- U54-HG003067/HG/NHGRI NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2011 Aug 19;333(6045):1019-24. doi: 10.1126/science.1202702.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Center for Biomolecular Science and Engineering, University of California, Santa Cruz, CA 95064, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/21852499" target="_blank"〉PubMed〈/a〉

    Description: Rett syndrome (RTT) is a postnatal neurological disorder caused by mutations in MECP2, encoding the epigenetic regulator methyl-CpG-binding protein 2 (MeCP2). The onset of RTT symptoms during early life together with findings suggesting neurodevelopmental abnormalities in RTT and mouse models of RTT raised the question of whether maintaining MeCP2 function exclusively during early life might protect against disease. We show by using an inducible model of RTT that deletion of Mecp2 in adult mice recapitulates the germline knock-out phenotype, underscoring the ongoing role of MeCP2 in adult neurological function. Moreover, unlike the effects of other epigenetic instructions programmed during early life, the effects of early MeCP2 function are lost soon after its deletion. These findings suggest that therapies for RTT must be maintained throughout life.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3150190/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3150190/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉McGraw, Christopher M -- Samaco, Rodney C -- Zoghbi, Huda Y -- F31-NS073317/NS/NINDS NIH HHS/ -- HD024064/HD/NICHD NIH HHS/ -- NS057819/NS/NINDS NIH HHS/ -- P30 HD024064/HD/NICHD NIH HHS/ -- P30 HD024064-22/HD/NICHD NIH HHS/ -- R01 NS057819/NS/NINDS NIH HHS/ -- R01 NS057819-05/NS/NINDS NIH HHS/ -- T32-NS043124/NS/NINDS NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2011 Jul 8;333(6039):186. doi: 10.1126/science.1206593.

    Description: Regeneration requires initiation of programs tailored to the identity of missing parts. Head-versus-tail regeneration in planarians presents a paradigm for study of this phenomenon. After injury, Wnt signaling promotes tail regeneration. We report that wounding elicits expression of the Wnt inhibitor notum preferentially at anterior-facing wounds. This expression asymmetry occurs at essentially any wound, even if the anterior pole is intact. Inhibition of notum with RNA interference (RNAi) causes regeneration of an anterior-facing tail instead of a head, and double-RNAi experiments indicate that notum inhibits Wnt signaling to promote head regeneration. notum expression is itself controlled by Wnt signaling, suggesting that regulation of feedback inhibition controls the binary head-tail regeneration outcome. We conclude that local detection of wound orientation with respect to tissue axes results in distinct signaling environments that initiate appropriate regeneration responses.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3320723/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3320723/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Petersen, Christian P -- Reddien, Peter W -- R01 GM080639/GM/NIGMS NIH HHS/ -- R01 GM080639-04/GM/NIGMS NIH HHS/ -- R01GM080639/GM/NIGMS NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2011 May 13;332(6031):852-5. doi: 10.1126/science.1202143.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Whitehead Institute for Biomedical Research, Cambridge, MA 02142, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/21566195" target="_blank"〉PubMed〈/a〉

    Description: Intracellular pathogens such as Listeria monocytogenes subvert cellular functions through the interaction of bacterial effectors with host components. Here we found that a secreted listerial virulence factor, LntA, could target the chromatin repressor BAHD1 in the host cell nucleus to activate interferon (IFN)-stimulated genes (ISGs). IFN-lambda expression was induced in response to infection of epithelial cells with bacteria lacking LntA; however, the BAHD1-chromatin associated complex repressed downstream ISGs. In contrast, in cells infected with lntA-expressing bacteria, LntA prevented BAHD1 recruitment to ISGs and stimulated their expression. Murine listeriosis decreased in BAHD1(+/-) mice or when lntA was constitutively expressed. Thus, the LntA-BAHD1 interplay may modulate IFN-lambda-mediated immune response to control bacterial colonization of the host.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lebreton, Alice -- Lakisic, Goran -- Job, Viviana -- Fritsch, Lauriane -- Tham, To Nam -- Camejo, Ana -- Mattei, Pierre-Jean -- Regnault, Beatrice -- Nahori, Marie-Anne -- Cabanes, Didier -- Gautreau, Alexis -- Ait-Si-Ali, Slimane -- Dessen, Andrea -- Cossart, Pascale -- Bierne, Helene -- 233348/European Research Council/International -- New York, N.Y. -- Science. 2011 Mar 11;331(6022):1319-21. doi: 10.1126/science.1200120.

    Description: The vast majority of proteins that a cell secretes or displays on its surface first enter the endoplasmic reticulum (ER), where they fold and assemble. Only properly assembled proteins advance from the ER to the cell surface. To ascertain fidelity in protein folding, cells regulate the protein-folding capacity in the ER according to need. The ER responds to the burden of unfolded proteins in its lumen (ER stress) by activating intracellular signal transduction pathways, collectively termed the unfolded protein response (UPR). Together, at least three mechanistically distinct branches of the UPR regulate the expression of numerous genes that maintain homeostasis in the ER or induce apoptosis if ER stress remains unmitigated. Recent advances shed light on mechanistic complexities and on the role of the UPR in numerous diseases.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Walter, Peter -- Ron, David -- Howard Hughes Medical Institute/ -- Wellcome Trust/United Kingdom -- New York, N.Y. -- Science. 2011 Nov 25;334(6059):1081-6. doi: 10.1126/science.1209038.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Howard Hughes Medical Institute and Department of Biochemistry and Biophysics, University of California, San Francisco, CA 94158, USA. peter@walterlab.ucsf.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/22116877" target="_blank"〉PubMed〈/a〉

    Description: Autophagy is a cellular catabolic process that relies on the cooperation of autophagosomes and lysosomes. During starvation, the cell expands both compartments to enhance degradation processes. We found that starvation activates a transcriptional program that controls major steps of the autophagic pathway, including autophagosome formation, autophagosome-lysosome fusion, and substrate degradation. The transcription factor EB (TFEB), a master gene for lysosomal biogenesis, coordinated this program by driving expression of autophagy and lysosomal genes. Nuclear localization and activity of TFEB were regulated by serine phosphorylation mediated by the extracellular signal-regulated kinase 2, whose activity was tuned by the levels of extracellular nutrients. Thus, a mitogen-activated protein kinase-dependent mechanism regulates autophagy by controlling the biogenesis and partnership of two distinct cellular organelles.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3638014/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3638014/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Settembre, Carmine -- Di Malta, Chiara -- Polito, Vinicia Assunta -- Garcia Arencibia, Moises -- Vetrini, Francesco -- Erdin, Serkan -- Erdin, Serpil Uckac -- Huynh, Tuong -- Medina, Diego -- Colella, Pasqualina -- Sardiello, Marco -- Rubinsztein, David C -- Ballabio, Andrea -- 250154/European Research Council/International -- 5 P30 HD024064/HD/NICHD NIH HHS/ -- G0600194/Medical Research Council/United Kingdom -- P30 HD024064/HD/NICHD NIH HHS/ -- R01 NS078072/NS/NINDS NIH HHS/ -- TGM11CB6/Telethon/Italy -- Medical Research Council/United Kingdom -- Wellcome Trust/United Kingdom -- New York, N.Y. -- Science. 2011 Jun 17;332(6036):1429-33. doi: 10.1126/science.1204592.

    Description: We describe the draft genome of the microcrustacean Daphnia pulex, which is only 200 megabases and contains at least 30,907 genes. The high gene count is a consequence of an elevated rate of gene duplication resulting in tandem gene clusters. More than a third of Daphnia's genes have no detectable homologs in any other available proteome, and the most amplified gene families are specific to the Daphnia lineage. The coexpansion of gene families interacting within metabolic pathways suggests that the maintenance of duplicated genes is not random, and the analysis of gene expression under different environmental conditions reveals that numerous paralogs acquire divergent expression patterns soon after duplication. Daphnia-specific genes, including many additional loci within sequenced regions that are otherwise devoid of annotations, are the most responsive genes to ecological challenges.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3529199/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3529199/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Colbourne, John K -- Pfrender, Michael E -- Gilbert, Donald -- Thomas, W Kelley -- Tucker, Abraham -- Oakley, Todd H -- Tokishita, Shinichi -- Aerts, Andrea -- Arnold, Georg J -- Basu, Malay Kumar -- Bauer, Darren J -- Caceres, Carla E -- Carmel, Liran -- Casola, Claudio -- Choi, Jeong-Hyeon -- Detter, John C -- Dong, Qunfeng -- Dusheyko, Serge -- Eads, Brian D -- Frohlich, Thomas -- Geiler-Samerotte, Kerry A -- Gerlach, Daniel -- Hatcher, Phil -- Jogdeo, Sanjuro -- Krijgsveld, Jeroen -- Kriventseva, Evgenia V -- Kultz, Dietmar -- Laforsch, Christian -- Lindquist, Erika -- Lopez, Jacqueline -- Manak, J Robert -- Muller, Jean -- Pangilinan, Jasmyn -- Patwardhan, Rupali P -- Pitluck, Samuel -- Pritham, Ellen J -- Rechtsteiner, Andreas -- Rho, Mina -- Rogozin, Igor B -- Sakarya, Onur -- Salamov, Asaf -- Schaack, Sarah -- Shapiro, Harris -- Shiga, Yasuhiro -- Skalitzky, Courtney -- Smith, Zachary -- Souvorov, Alexander -- Sung, Way -- Tang, Zuojian -- Tsuchiya, Dai -- Tu, Hank -- Vos, Harmjan -- Wang, Mei -- Wolf, Yuri I -- Yamagata, Hideo -- Yamada, Takuji -- Ye, Yuzhen -- Shaw, Joseph R -- Andrews, Justen -- Crease, Teresa J -- Tang, Haixu -- Lucas, Susan M -- Robertson, Hugh M -- Bork, Peer -- Koonin, Eugene V -- Zdobnov, Evgeny M -- Grigoriev, Igor V -- Lynch, Michael -- Boore, Jeffrey L -- P42 ES004699/ES/NIEHS NIH HHS/ -- P42 ES004699-25/ES/NIEHS NIH HHS/ -- P42ES004699/ES/NIEHS NIH HHS/ -- R01 ES019324/ES/NIEHS NIH HHS/ -- R24 GM078274/GM/NIGMS NIH HHS/ -- R24 GM078274-01A1/GM/NIGMS NIH HHS/ -- R24GM07827401/GM/NIGMS NIH HHS/ -- Intramural NIH HHS/ -- New York, N.Y. -- Science. 2011 Feb 4;331(6017):555-61. doi: 10.1126/science.1197761.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Center for Genomics and Bioinformatics, Indiana University, 915 East Third Street, Bloomington, IN 47405, USA. jcolbour@indiana.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/21292972" target="_blank"〉PubMed〈/a〉

    Description: In animals, circadian oscillators are based on a transcription-translation circuit that revolves around the transcription factors CLOCK and BMAL1. We found that the JumonjiC (JmjC) and ARID domain-containing histone lysine demethylase 1a (JARID1a) formed a complex with CLOCK-BMAL1, which was recruited to the Per2 promoter. JARID1a increased histone acetylation by inhibiting histone deacetylase 1 function and enhanced transcription by CLOCK-BMAL1 in a demethylase-independent manner. Depletion of JARID1a in mammalian cells reduced Per promoter histone acetylation, dampened expression of canonical circadian genes, and shortened the period of circadian rhythms. Drosophila lines with reduced expression of the Jarid1a homolog, lid, had lowered Per expression and similarly altered circadian rhythms. JARID1a thus has a nonredundant role in circadian oscillator function.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3204309/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3204309/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉DiTacchio, Luciano -- Le, Hiep D -- Vollmers, Christopher -- Hatori, Megumi -- Witcher, Michael -- Secombe, Julie -- Panda, Satchidananda -- DK 091618/DK/NIDDK NIH HHS/ -- EY 16807/EY/NEI NIH HHS/ -- F32GM082083/GM/NIGMS NIH HHS/ -- R01 DK091618/DK/NIDDK NIH HHS/ -- R01 EY016807/EY/NEI NIH HHS/ -- S10 RR027450/RR/NCRR NIH HHS/ -- New York, N.Y. -- Science. 2011 Sep 30;333(6051):1881-5. doi: 10.1126/science.1206022.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Regulatory Biology Laboratory, Salk Institute for Biological Studies, La Jolla, CA 92037, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/21960634" target="_blank"〉PubMed〈/a〉

    Description: The organized societies of ants include short-lived worker castes displaying specialized behavior and morphology and long-lived queens dedicated to reproduction. We sequenced and compared the genomes of two socially divergent ant species: Camponotus floridanus and Harpegnathos saltator. Both genomes contained high amounts of CpG, despite the presence of DNA methylation, which in non-Hymenoptera correlates with CpG depletion. Comparison of gene expression in different castes identified up-regulation of telomerase and sirtuin deacetylases in longer-lived H. saltator reproductives, caste-specific expression of microRNAs and SMYD histone methyltransferases, and differential regulation of genes implicated in neuronal function and chemical communication. Our findings provide clues on the molecular differences between castes in these two ants and establish a new experimental model to study epigenetics in aging and behavior.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3772619/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3772619/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bonasio, Roberto -- Zhang, Guojie -- Ye, Chaoyang -- Mutti, Navdeep S -- Fang, Xiaodong -- Qin, Nan -- Donahue, Greg -- Yang, Pengcheng -- Li, Qiye -- Li, Cai -- Zhang, Pei -- Huang, Zhiyong -- Berger, Shelley L -- Reinberg, Danny -- Wang, Jun -- Liebig, Jurgen -- 2009005/Howard Hughes Medical Institute/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2010 Aug 27;329(5995):1068-71. doi: 10.1126/science.1192428.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biochemistry, New York University School of Medicine, 522 First Avenue, New York, NY 10016, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20798317" target="_blank"〉PubMed〈/a〉

    Description: Cocaine-induced alterations in gene expression cause changes in neuronal morphology and behavior that may underlie cocaine addiction. In mice, we identified an essential role for histone 3 lysine 9 (H3K9) dimethylation and the lysine dimethyltransferase G9a in cocaine-induced structural and behavioral plasticity. Repeated cocaine administration reduced global levels of H3K9 dimethylation in the nucleus accumbens. This reduction in histone methylation was mediated through the repression of G9a in this brain region, which was regulated by the cocaine-induced transcription factor DeltaFosB. Using conditional mutagenesis and viral-mediated gene transfer, we found that G9a down-regulation increased the dendritic spine plasticity of nucleus accumbens neurons and enhanced the preference for cocaine, thereby establishing a crucial role for histone methylation in the long-term actions of cocaine.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2820240/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2820240/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Maze, Ian -- Covington, Herbert E 3rd -- Dietz, David M -- LaPlant, Quincey -- Renthal, William -- Russo, Scott J -- Mechanic, Max -- Mouzon, Ezekiell -- Neve, Rachael L -- Haggarty, Stephen J -- Ren, Yanhua -- Sampath, Srihari C -- Hurd, Yasmin L -- Greengard, Paul -- Tarakhovsky, Alexander -- Schaefer, Anne -- Nestler, Eric J -- P01 DA008227/DA/NIDA NIH HHS/ -- P01 DA008227-120001/DA/NIDA NIH HHS/ -- P01 DA008227-129001/DA/NIDA NIH HHS/ -- P01 DA008227-13/DA/NIDA NIH HHS/ -- P01 DA008227-14/DA/NIDA NIH HHS/ -- P01 DA008227-15/DA/NIDA NIH HHS/ -- P01 DA008227-16/DA/NIDA NIH HHS/ -- P01 DA008227-170003/DA/NIDA NIH HHS/ -- P01 DA008227-180003/DA/NIDA NIH HHS/ -- P01 DA010044/DA/NIDA NIH HHS/ -- P01 DA010044-14/DA/NIDA NIH HHS/ -- P01 DA010044-140005/DA/NIDA NIH HHS/ -- P01 DA010044-149002/DA/NIDA NIH HHS/ -- P01 DA010044-14S1/DA/NIDA NIH HHS/ -- P01 DA010044-14S10005/DA/NIDA NIH HHS/ -- P01 DA010044-14S19002/DA/NIDA NIH HHS/ -- P01 DA010044-15/DA/NIDA NIH HHS/ -- P01 DA010044-150005/DA/NIDA NIH HHS/ -- P01 DA010044-159002/DA/NIDA NIH HHS/ -- P01 DA08227/DA/NIDA NIH HHS/ -- P0110044/PHS HHS/ -- R01 DA007359/DA/NIDA NIH HHS/ -- R01 DA007359-02/DA/NIDA NIH HHS/ -- R01 DA007359-17/DA/NIDA NIH HHS/ -- R01 DA007359-18/DA/NIDA NIH HHS/ -- R01 DA007359-19/DA/NIDA NIH HHS/ -- R01 DA007359-20/DA/NIDA NIH HHS/ -- R01 DA007359-21/DA/NIDA NIH HHS/ -- R01 DA007359-22/DA/NIDA NIH HHS/ -- R01 DA014133/DA/NIDA NIH HHS/ -- R01 DA07359/DA/NIDA NIH HHS/ -- New York, N.Y. -- Science. 2010 Jan 8;327(5962):213-6. doi: 10.1126/science.1179438.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Fishberg Department of Neuroscience, Mount Sinai School of Medicine, New York, NY, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20056891" target="_blank"〉PubMed〈/a〉

    Description: Extracellular matrices in diverse biological systems are cross-linked by dityrosine covalent bonds catalyzed by the peroxidase/oxidase system. We show that a peroxidase, secreted by the Anopheles gambiae midgut, and dual oxidase form a dityrosine network that decreases gut permeability to immune elicitors. This network protects the microbiota by preventing activation of epithelial immunity. It also provides a suitable environment for malaria parasites to develop within the midgut lumen without inducing nitric oxide synthase expression. Disruption of this barrier results in strong and effective pathogen-specific immune responses.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3510679/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3510679/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kumar, Sanjeev -- Molina-Cruz, Alvaro -- Gupta, Lalita -- Rodrigues, Janneth -- Barillas-Mury, Carolina -- ZIA AI000947-08/Intramural NIH HHS/ -- New York, N.Y. -- Science. 2010 Mar 26;327(5973):1644-8. doi: 10.1126/science.1184008.

    Description: The mammalian adenosine monophosphate-activated protein kinase (AMPK) is a serine-threonine kinase protein complex that is a central regulator of cellular energy homeostasis. However, the mechanisms by which AMPK mediates cellular responses to metabolic stress remain unclear. We found that AMPK activates transcription through direct association with chromatin and phosphorylation of histone H2B at serine 36. AMPK recruitment and H2B Ser36 phosphorylation colocalized within genes activated by AMPK-dependent pathways, both in promoters and in transcribed regions. Ectopic expression of H2B in which Ser36 was substituted by alanine reduced transcription and RNA polymerase II association to AMPK-dependent genes, and lowered cell survival in response to stress. Our results place AMPK-dependent H2B Ser36 phosphorylation in a direct transcriptional and chromatin regulatory pathway leading to cellular adaptation to stress.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3922052/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3922052/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bungard, David -- Fuerth, Benjamin J -- Zeng, Ping-Yao -- Faubert, Brandon -- Maas, Nancy L -- Viollet, Benoit -- Carling, David -- Thompson, Craig B -- Jones, Russell G -- Berger, Shelley L -- CA078831/CA/NCI NIH HHS/ -- CA09171/CA/NCI NIH HHS/ -- CA105463/CA/NCI NIH HHS/ -- MC_U120027537/Medical Research Council/United Kingdom -- MOP-93799/Canadian Institutes of Health Research/Canada -- P01 AG031862/AG/NIA NIH HHS/ -- P01 CA104838/CA/NCI NIH HHS/ -- R01 CA078831/CA/NCI NIH HHS/ -- R01 CA105463/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 2010 Sep 3;329(5996):1201-5. doi: 10.1126/science.1191241.

    Description: Despite the importance of myelin for the rapid conduction of action potentials, the molecular bases of oligodendrocyte differentiation and central nervous system (CNS) myelination are still incompletely understood. Recent results have greatly advanced this understanding, identifying new transcriptional regulators of myelin gene expression, elucidating vital roles for microRNAs in controlling myelination, and clarifying the extracellular signaling mechanisms that orchestrate the development of myelin. Studies have also demonstrated an unexpected level of plasticity of myelin in the adult CNS. These recent advances provide new insight into how remyelination may be stimulated in demyelinating disorders such as multiple sclerosis.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Emery, Ben -- New York, N.Y. -- Science. 2010 Nov 5;330(6005):779-82. doi: 10.1126/science.1190927.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Centre for Neuroscience and Florey Neuroscience Institutes, Level 2, Alan Gilbert Building, The University of Melbourne, 161 Barry Street, Carlton South, Victoria 3053, Australia. emeryb@unimelb.edu.au〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/21051629" target="_blank"〉PubMed〈/a〉

    Description: The mosquito Culex quinquefasciatus poses a substantial threat to human and veterinary health as a primary vector of West Nile virus (WNV), the filarial worm Wuchereria bancrofti, and an avian malaria parasite. Comparative phylogenomics revealed an expanded canonical C. quinquefasciatus immune gene repertoire compared with those of Aedes aegypti and Anopheles gambiae. Transcriptomic analysis of C. quinquefasciatus genes responsive to WNV, W. bancrofti, and non-native bacteria facilitated an unprecedented meta-analysis of 25 vector-pathogen interactions involving arboviruses, filarial worms, bacteria, and malaria parasites, revealing common and distinct responses to these pathogen types in three mosquito genera. Our findings provide support for the hypothesis that mosquito-borne pathogens have evolved to evade innate immune responses in three vector mosquito species of major medical importance.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3104938/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3104938/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bartholomay, Lyric C -- Waterhouse, Robert M -- Mayhew, George F -- Campbell, Corey L -- Michel, Kristin -- Zou, Zhen -- Ramirez, Jose L -- Das, Suchismita -- Alvarez, Kanwal -- Arensburger, Peter -- Bryant, Bart -- Chapman, Sinead B -- Dong, Yuemei -- Erickson, Sara M -- Karunaratne, S H P Parakrama -- Kokoza, Vladimir -- Kodira, Chinnappa D -- Pignatelli, Patricia -- Shin, Sang Woon -- Vanlandingham, Dana L -- Atkinson, Peter W -- Birren, Bruce -- Christophides, George K -- Clem, Rollie J -- Hemingway, Janet -- Higgs, Stephen -- Megy, Karine -- Ranson, Hilary -- Zdobnov, Evgeny M -- Raikhel, Alexander S -- Christensen, Bruce M -- Dimopoulos, George -- Muskavitch, Marc A T -- F31 AI080161/AI/NIAID NIH HHS/ -- F31 AI080161-01A1/AI/NIAID NIH HHS/ -- HHSN266200400001C/AO/NIAID NIH HHS/ -- HHSN266200400001C/PHS HHS/ -- HHSN266200400039C/AI/NIAID NIH HHS/ -- HHSN266200400039C/PHS HHS/ -- P20 RR017686/RR/NCRR NIH HHS/ -- P20 RR017686-01/RR/NCRR NIH HHS/ -- R01 AI019769/AI/NIAID NIH HHS/ -- R01 AI019769-26/AI/NIAID NIH HHS/ -- R01 AI059492/AI/NIAID NIH HHS/ -- R01 AI059492-05/AI/NIAID NIH HHS/ -- R01 AI061576/AI/NIAID NIH HHS/ -- R01 AI061576-08/AI/NIAID NIH HHS/ -- R01 AI067698/AI/NIAID NIH HHS/ -- R01 AI067698-05/AI/NIAID NIH HHS/ -- R01 AI078997/AI/NIAID NIH HHS/ -- R01 AI078997-02/AI/NIAID NIH HHS/ -- R01 AI095842/AI/NIAID NIH HHS/ -- R01 AI19769/AI/NIAID NIH HHS/ -- R01 AI59492/AI/NIAID NIH HHS/ -- R01 AI67698/AI/NIAID NIH HHS/ -- R21 AI067642/AI/NIAID NIH HHS/ -- R21 AI067642-01/AI/NIAID NIH HHS/ -- T01CCT622892/PHS HHS/ -- T32 A107536/PHS HHS/ -- T32 AI007414/AI/NIAID NIH HHS/ -- T32 AI007417/AI/NIAID NIH HHS/ -- Wellcome Trust/United Kingdom -- New York, N.Y. -- Science. 2010 Oct 1;330(6000):88-90. doi: 10.1126/science.1193162.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Entomology, Iowa State University, Ames, IA 50011, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20929811" target="_blank"〉PubMed〈/a〉

    Description: Circadian clocks align behavioral and biochemical processes with the day/night cycle. Nearly all vertebrate cells possess self-sustained clocks that couple endogenous rhythms with changes in cellular environment. Genetic disruption of clock genes in mice perturbs metabolic functions of specific tissues at distinct phases of the sleep/wake cycle. Circadian desynchrony, a characteristic of shift work and sleep disruption in humans, also leads to metabolic pathologies. Here, we review advances in understanding the interrelationship among circadian disruption, sleep deprivation, obesity, and diabetes and implications for rational therapeutics for these conditions.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3756146/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3756146/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bass, Joseph -- Takahashi, Joseph S -- P01 AG011412/AG/NIA NIH HHS/ -- P50 MH074924/MH/NIMH NIH HHS/ -- R01 HL097817/HL/NHLBI NIH HHS/ -- R01 MH078024/MH/NIMH NIH HHS/ -- R01HL097817/HL/NHLBI NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2010 Dec 3;330(6009):1349-54. doi: 10.1126/science.1195027.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Medicine, Northwestern University, Feinberg School of Medicine, Chicago, IL 60611, USA. j-bass@northwestern.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/21127246" target="_blank"〉PubMed〈/a〉

    Description: To gain insight into how genomic information is translated into cellular and developmental programs, the Drosophila model organism Encyclopedia of DNA Elements (modENCODE) project is comprehensively mapping transcripts, histone modifications, chromosomal proteins, transcription factors, replication proteins and intermediates, and nucleosome properties across a developmental time course and in multiple cell lines. We have generated more than 700 data sets and discovered protein-coding, noncoding, RNA regulatory, replication, and chromatin elements, more than tripling the annotated portion of the Drosophila genome. Correlated activity patterns of these elements reveal a functional regulatory network, which predicts putative new functions for genes, reveals stage- and tissue-specific regulators, and enables gene-expression prediction. Our results provide a foundation for directed experimental and computational studies in Drosophila and related species and also a model for systematic data integration toward comprehensive genomic and functional annotation.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3192495/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3192495/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉modENCODE Consortium -- Roy, Sushmita -- Ernst, Jason -- Kharchenko, Peter V -- Kheradpour, Pouya -- Negre, Nicolas -- Eaton, Matthew L -- Landolin, Jane M -- Bristow, Christopher A -- Ma, Lijia -- Lin, Michael F -- Washietl, Stefan -- Arshinoff, Bradley I -- Ay, Ferhat -- Meyer, Patrick E -- Robine, Nicolas -- Washington, Nicole L -- Di Stefano, Luisa -- Berezikov, Eugene -- Brown, Christopher D -- Candeias, Rogerio -- Carlson, Joseph W -- Carr, Adrian -- Jungreis, Irwin -- Marbach, Daniel -- Sealfon, Rachel -- Tolstorukov, Michael Y -- Will, Sebastian -- Alekseyenko, Artyom A -- Artieri, Carlo -- Booth, Benjamin W -- Brooks, Angela N -- Dai, Qi -- Davis, Carrie A -- Duff, Michael O -- Feng, Xin -- Gorchakov, Andrey A -- Gu, Tingting -- Henikoff, Jorja G -- Kapranov, Philipp -- Li, Renhua -- MacAlpine, Heather K -- Malone, John -- Minoda, Aki -- Nordman, Jared -- Okamura, Katsutomo -- Perry, Marc -- Powell, Sara K -- Riddle, Nicole C -- Sakai, Akiko -- Samsonova, Anastasia -- Sandler, Jeremy E -- Schwartz, Yuri B -- Sher, Noa -- Spokony, Rebecca -- Sturgill, David -- van Baren, Marijke -- Wan, Kenneth H -- Yang, Li -- Yu, Charles -- Feingold, Elise -- Good, Peter -- Guyer, Mark -- Lowdon, Rebecca -- Ahmad, Kami -- Andrews, Justen -- Berger, Bonnie -- Brenner, Steven E -- Brent, Michael R -- Cherbas, Lucy -- Elgin, Sarah C R -- Gingeras, Thomas R -- Grossman, Robert -- Hoskins, Roger A -- Kaufman, Thomas C -- Kent, William -- Kuroda, Mitzi I -- Orr-Weaver, Terry -- Perrimon, Norbert -- Pirrotta, Vincenzo -- Posakony, James W -- Ren, Bing -- Russell, Steven -- Cherbas, Peter -- Graveley, Brenton R -- Lewis, Suzanna -- Micklem, Gos -- Oliver, Brian -- Park, Peter J -- Celniker, Susan E -- Henikoff, Steven -- Karpen, Gary H -- Lai, Eric C -- MacAlpine, David M -- Stein, Lincoln D -- White, Kevin P -- Kellis, Manolis -- R01 HG004037/HG/NHGRI NIH HHS/ -- R01HG004037/HG/NHGRI NIH HHS/ -- RC2HG005639/HG/NHGRI NIH HHS/ -- U01 HG004258/HG/NHGRI NIH HHS/ -- U01 HG004271/HG/NHGRI NIH HHS/ -- U01 HG004279/HG/NHGRI NIH HHS/ -- U01HG004258/HG/NHGRI NIH HHS/ -- U01HG004261/HG/NHGRI NIH HHS/ -- U01HG004264/HG/NHGRI NIH HHS/ -- U01HG004271/HG/NHGRI NIH HHS/ -- U01HG004274/HG/NHGRI NIH HHS/ -- U01HG004279/HG/NHGRI NIH HHS/ -- U41HG004269/HG/NHGRI NIH HHS/ -- ZIA DK015600-14/Intramural NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2010 Dec 24;330(6012):1787-97. doi: 10.1126/science.1198374.

    Description: Proper coordination of cholesterol biosynthesis and trafficking is essential to human health. The sterol regulatory element-binding proteins (SREBPs) are key transcription regulators of genes involved in cholesterol biosynthesis and uptake. We show here that microRNAs (miR-33a/b) embedded within introns of the SREBP genes target the adenosine triphosphate-binding cassette transporter A1 (ABCA1), an important regulator of high-density lipoprotein (HDL) synthesis and reverse cholesterol transport, for posttranscriptional repression. Antisense inhibition of miR-33 in mouse and human cell lines causes up-regulation of ABCA1 expression and increased cholesterol efflux, and injection of mice on a western-type diet with locked nucleic acid-antisense oligonucleotides results in elevated plasma HDL. Our findings indicate that miR-33 acts in concert with the SREBP host genes to control cholesterol homeostasis and suggest that miR-33 may represent a therapeutic target for ameliorating cardiometabolic diseases.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3840500/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3840500/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Najafi-Shoushtari, S Hani -- Kristo, Fjoralba -- Li, Yingxia -- Shioda, Toshi -- Cohen, David E -- Gerszten, Robert E -- Naar, Anders M -- P30 DK034854/DK/NIDDK NIH HHS/ -- P30 DK34854/DK/NIDDK NIH HHS/ -- R01 DK048873/DK/NIDDK NIH HHS/ -- R01 DK056626/DK/NIDDK NIH HHS/ -- R01 GM071449/GM/NIGMS NIH HHS/ -- R01DK48873/DK/NIDDK NIH HHS/ -- R01DK56626/DK/NIDDK NIH HHS/ -- R01GM071449/GM/NIGMS NIH HHS/ -- R21 DK084459/DK/NIDDK NIH HHS/ -- R21DK084459/DK/NIDDK NIH HHS/ -- R37 DK048873/DK/NIDDK NIH HHS/ -- New York, N.Y. -- Science. 2010 Jun 18;328(5985):1566-9. doi: 10.1126/science.1189123.

    Description: CD4+ T cells are critical for host defense but are also major drivers of immune-mediated disease. These T cells specialize to become distinct subsets and produce restricted patterns of cytokines, which are tailored to combat various microbial pathogens. Although classically viewed as distinct lineages, recent work calls into question whether helper CD4+ T cell subsets are more appropriately viewed as terminally differentiated cells or works in progress. Herein, we review recent advances that pertain to this topic and the mechanisms that contribute to helper CD4+ T cell commitment and plasticity. The therapeutic implications of these new findings are also considered.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2997673/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2997673/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉O'Shea, John J -- Paul, William E -- Z01 AR041106-13/Intramural NIH HHS/ -- Z01 AR041106-14/Intramural NIH HHS/ -- Z01 AR041132-07/Intramural NIH HHS/ -- Z01 AR041159-01/Intramural NIH HHS/ -- Z01 AR041160-01/Intramural NIH HHS/ -- Z01 AR041167-01/Intramural NIH HHS/ -- ZIA AR041106-15/Intramural NIH HHS/ -- ZIA AR041159-02/Intramural NIH HHS/ -- ZIA AR041161-02/Intramural NIH HHS/ -- ZIA AR041167-02/Intramural NIH HHS/ -- New York, N.Y. -- Science. 2010 Feb 26;327(5969):1098-102. doi: 10.1126/science.1178334.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Molecular Immunology and Inflammation Branch, National Institute of Arthritis and Musculoskeletal and Skin Diseases, National Institutes of Health, Bethesda, MD 20892-1616, USA. osheajo@mail.nih.gov〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20185720" target="_blank"〉PubMed〈/a〉

    Description: Population density-dependent dispersal is a well-characterized strategy of animal behavior in which dispersal rate increases when population density is higher. Caenorhabditis elegans shows positive chemotaxis to a set of odorants, but the chemotaxis switches from attraction to dispersal after prolonged exposure to the odorants. We show here that this plasticity of olfactory behavior is dependent on population density and that this regulation is mediated by pheromonal signaling. We show that a peptide, suppressor of NEP-2 (SNET-1), negatively regulates olfactory plasticity and that its expression is down-regulated by the pheromone. NEP-2, a homolog of the extracellular peptidase neprilysin, antagonizes SNET-1, and this function is essential for olfactory plasticity. These results suggest that population density information is transmitted through the external pheromone and endogenous peptide signaling to modulate chemotactic behavior.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3021133/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3021133/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Yamada, Koji -- Hirotsu, Takaaki -- Matsuki, Masahiro -- Butcher, Rebecca A -- Tomioka, Masahiro -- Ishihara, Takeshi -- Clardy, Jon -- Kunitomo, Hirofumi -- Iino, Yuichi -- CA24487/CA/NCI NIH HHS/ -- GM087533/GM/NIGMS NIH HHS/ -- K99 GM087533/GM/NIGMS NIH HHS/ -- K99 GM087533-01/GM/NIGMS NIH HHS/ -- R00 GM087533/GM/NIGMS NIH HHS/ -- R00 GM087533-03/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2010 Sep 24;329(5999):1647-50. doi: 10.1126/science.1192020.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biophysics and Biochemistry, Graduate School of Science, University of Tokyo, Tokyo 113-0032, Japan.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20929849" target="_blank"〉PubMed〈/a〉

    Description: Sestrins are conserved proteins that accumulate in cells exposed to stress, potentiate adenosine monophosphate-activated protein kinase (AMPK), and inhibit activation of target of rapamycin (TOR). We show that the abundance of Drosophila sestrin (dSesn) is increased upon chronic TOR activation through accumulation of reactive oxygen species that cause activation of c-Jun amino-terminal kinase and transcription factor Forkhead box O (FoxO). Loss of dSesn resulted in age-associated pathologies including triglyceride accumulation, mitochondrial dysfunction, muscle degeneration, and cardiac malfunction, which were prevented by pharmacological activation of AMPK or inhibition of TOR. Hence, dSesn appears to be a negative feedback regulator of TOR that integrates metabolic and stress inputs and prevents pathologies caused by chronic TOR activation that may result from diminished autophagic clearance of damaged mitochondria, protein aggregates, or lipids.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2866632/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2866632/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lee, Jun Hee -- Budanov, Andrei V -- Park, Eek Joong -- Birse, Ryan -- Kim, Teddy E -- Perkins, Guy A -- Ocorr, Karen -- Ellisman, Mark H -- Bodmer, Rolf -- Bier, Ethan -- Karin, Michael -- AI070654/AI/NIAID NIH HHS/ -- CA118165/CA/NCI NIH HHS/ -- DK082080/DK/NIDDK NIH HHS/ -- ES006376/ES/NIEHS NIH HHS/ -- NS29870/NS/NINDS NIH HHS/ -- P30 CA023100/CA/NCI NIH HHS/ -- P30-CA23100/CA/NCI NIH HHS/ -- P41-RR004050/RR/NCRR NIH HHS/ -- P42 ES010337/ES/NIEHS NIH HHS/ -- P42 ES010337-10S20010/ES/NIEHS NIH HHS/ -- P42-ES010337/ES/NIEHS NIH HHS/ -- R01 CA118165/CA/NCI NIH HHS/ -- R01 CA118165-04/CA/NCI NIH HHS/ -- R01 ES006376/ES/NIEHS NIH HHS/ -- R01 ES006376-17/ES/NIEHS NIH HHS/ -- New York, N.Y. -- Science. 2010 Mar 5;327(5970):1223-8. doi: 10.1126/science.1182228.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratory of Gene Regulation and Signal Transduction, Department of Pharmacology, School of Medicine, University of California San Diego (UCSD), La Jolla, CA 92093-0723, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20203043" target="_blank"〉PubMed〈/a〉

    Description: Cholesterol metabolism is tightly regulated at the cellular level. Here we show that miR-33, an intronic microRNA (miRNA) located within the gene encoding sterol-regulatory element-binding factor-2 (SREBF-2), a transcriptional regulator of cholesterol synthesis, modulates the expression of genes involved in cellular cholesterol transport. In mouse and human cells, miR-33 inhibits the expression of the adenosine triphosphate-binding cassette (ABC) transporter, ABCA1, thereby attenuating cholesterol efflux to apolipoprotein A1. In mouse macrophages, miR-33 also targets ABCG1, reducing cholesterol efflux to nascent high-density lipoprotein (HDL). Lentiviral delivery of miR-33 to mice represses ABCA1 expression in the liver, reducing circulating HDL levels. Conversely, silencing of miR-33 in vivo increases hepatic expression of ABCA1 and plasma HDL levels. Thus, miR-33 appears to regulate both HDL biogenesis in the liver and cellular cholesterol efflux.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3114628/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3114628/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Rayner, Katey J -- Suarez, Yajaira -- Davalos, Alberto -- Parathath, Saj -- Fitzgerald, Michael L -- Tamehiro, Norimasa -- Fisher, Edward A -- Moore, Kathryn J -- Fernandez-Hernando, Carlos -- 1P30HL101270-01/HL/NHLBI NIH HHS/ -- P30 HL101270/HL/NHLBI NIH HHS/ -- R01 AG020255/AG/NIA NIH HHS/ -- R01 AG020255-09/AG/NIA NIH HHS/ -- R01AG02055/AG/NIA NIH HHS/ -- R01HL074136/HL/NHLBI NIH HHS/ -- R01HL084312/HL/NHLBI NIH HHS/ -- New York, N.Y. -- Science. 2010 Jun 18;328(5985):1570-3. doi: 10.1126/science.1189862.

    Description: Although dimorphic sexes have evolved repeatedly in multicellular eukaryotes, their origins are unknown. The mating locus (MT) of the sexually dimorphic multicellular green alga Volvox carteri specifies the production of eggs and sperm and has undergone a remarkable expansion and divergence relative to MT from Chlamydomonas reinhardtii, which is a closely related unicellular species that has equal-sized gametes. Transcriptome analysis revealed a rewired gametic expression program for Volvox MT genes relative to Chlamydomonas and identified multiple gender-specific and sex-regulated transcripts. The retinoblastoma tumor suppressor homolog MAT3 is a Volvox MT gene that displays sexually regulated alternative splicing and evidence of gender-specific selection, both of which are indicative of cooption into the sexual cycle. Thus, sex-determining loci affect the evolution of both sex-related and non-sex-related genes.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2880461/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2880461/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ferris, Patrick -- Olson, Bradley J S C -- De Hoff, Peter L -- Douglass, Stephen -- Casero, David -- Prochnik, Simon -- Geng, Sa -- Rai, Rhitu -- Grimwood, Jane -- Schmutz, Jeremy -- Nishii, Ichiro -- Hamaji, Takashi -- Nozaki, Hisayoshi -- Pellegrini, Matteo -- Umen, James G -- F32 GM086037/GM/NIGMS NIH HHS/ -- R01 GM078376/GM/NIGMS NIH HHS/ -- R01 GM078376-01/GM/NIGMS NIH HHS/ -- R01 GM078376-02/GM/NIGMS NIH HHS/ -- R01 GM078376-03/GM/NIGMS NIH HHS/ -- R01 GM078376-04/GM/NIGMS NIH HHS/ -- R01 GM078376-04S1/GM/NIGMS NIH HHS/ -- T32-HG002536/HG/NHGRI NIH HHS/ -- New York, N.Y. -- Science. 2010 Apr 16;328(5976):351-4. doi: 10.1126/science.1186222.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉The Salk Institute for Biological Studies, La Jolla, CA 92037, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20395508" target="_blank"〉PubMed〈/a〉

    Description: Eukaryotic cytosine methylation represses transcription but also occurs in the bodies of active genes, and the extent of methylation biology conservation is unclear. We quantified DNA methylation in 17 eukaryotic genomes and found that gene body methylation is conserved between plants and animals, whereas selective methylation of transposons is not. We show that methylation of plant transposons in the CHG context extends to green algae and that exclusion of histone H2A.Z from methylated DNA is conserved between plants and animals, and we present evidence for RNA-directed DNA methylation of fungal genes. Our data demonstrate that extant DNA methylation systems are mosaics of conserved and derived features, and indicate that gene body methylation is an ancient property of eukaryotic genomes.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Zemach, Assaf -- McDaniel, Ivy E -- Silva, Pedro -- Zilberman, Daniel -- New York, N.Y. -- Science. 2010 May 14;328(5980):916-9. doi: 10.1126/science.1186366.

    Description: Human and murine mononuclear phagocytes express a high-affinity receptor for immunoglobulin G that plays a central role in macrophage antibody-dependent cellular cytotoxicity and clearance of immune complexes. The receptor (FcRI) may also be involved in CD4-independent infection of human macrophages by human immunodeficiency virus. This report describes the isolation of cDNA clones encoding the human FcRI by a ligand-mediated selection technique. Expression of the cDNAs in COS cells gave rise to immunoglobulin G binding of the expected affinity and subtype specificity. RNA blot analysis revealed expression of a 1.7-kilobase transcript in macrophages and in cells of the promonocytic cell line U937 induced with interferon-gamma. The extracellular region of FcRI consists of three immunoglobulin-like domains, two of which share homology with low-affinity receptor domains.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Allen, J M -- Seed, B -- New York, N.Y. -- Science. 1989 Jan 20;243(4889):378-81.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Molecular Biology, Massachusetts General Hospital, Boston 02114.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2911749" target="_blank"〉PubMed〈/a〉

    Description: Tumor promoters may bring about events that lead to neoplastic transformation by inducing specific promotion-relevant effector genes. Functional activation of the transacting transcription factor AP-1 by the phorbol ester 12-O-tetradecanoylphorbol-13-acetate (TPA) may play an essential role in this process. Clonal genetic variants of mouse epidermal JB6 cells that are genetically susceptible (P+) or resistant (P-) to promotion of transformation by TPA were transfected with 3XTRE-CAT, a construct that has AP-1 cis-enhancer sequences attached to a reporter gene encoding chloramphenicol acetyltransferase (CAT). Transfected JB6 P+, but not P- variants, showed TPA-inducible CAT synthesis. Epidermal growth factor, another transformation promoter in JB6 cells, also caused P+ specific induction of CAT gene expression. These results demonstrate an association between induced AP-1 function and sensitivity to promotion of neoplastic transformation.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bernstein, L R -- Colburn, N H -- New York, N.Y. -- Science. 1989 May 5;244(4904):566-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Johns Hopkins University, Department of Biology, Baltimore, MD 21218.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2541502" target="_blank"〉PubMed〈/a〉

    Description: Nerve growth factor (NGF) interacts with both high affinity (Kd = 10(-10)-10(-11)M) and low affinity (Kd = 10(-8)-10(-9)M) receptors; the binding of NGF to the high affinity receptor is correlated with biological actions of NGF. To determine whether a single NGF binding protein is common to both forms of the receptor, a full-length receptor cDNA was introduced in the NR18 cell line, an NGF receptor-deficient variant of the PC12 pheochromocytoma cell line. The transformant displayed (i) both high and low affinity receptors detectable by receptor binding; (ii) an affinity cross-linking pattern with 125I-labeled NGF similar to that of the parent PC12 cell line; and (iii) biological responsiveness to NGF as assayed by induction of c-fos transcription. These findings support the hypothesis that a single binding protein is common to both forms of the NGF receptor and suggest that an additional protein is required to produce the high affinity form of the NGF receptor.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hempstead, B L -- Schleifer, L S -- Chao, M V -- HD23315/HD/NICHD NIH HHS/ -- NS-21072/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 1989 Jan 20;243(4889):373-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Division of Hematology/Oncology, Cornell University Medical College, New York, NY 10021.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2536190" target="_blank"〉PubMed〈/a〉

    Description: Soybean cultivars resistant to Pseudomonas syringae pathovar glycinea (Psg), the causal agent of bacterial blight, exhibit a hypersensitive (necrosis) reaction (HR) to infection. Psg strains carrying the avrB gene elicit the HR in soybean cultivars carrying the resistance gene Rpg1. Psg expressing avrB at a high level and capable of eliciting the HR in the absence of de novo bacterial RNA synthesis have been obtained in in vitro culture. Nutritional signals and regions within the Psg hrp gene cluster, an approximately 20-kilobase genomic region also necessary for pathogenicity, control avrB transcription.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Huynh, T V -- Dahlbeck, D -- Staskawicz, B J -- New York, N.Y. -- Science. 1989 Sep 22;245(4924):1374-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Plant Pathology, University of California, Berkeley 94720.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2781284" target="_blank"〉PubMed〈/a〉

    Description: Biochemical and electrophysiological studies suggest that odorants induce responses in olfactory sensory neurons via an adenylate cyclase cascade mediated by a G protein. An olfactory-specific guanosine triphosphate (GTP)-binding protein alpha subunit has now been characterized and evidence is presented suggesting that this G protein, termed Golf, mediates olfaction. Messenger RNA that encodes Golf alpha is expressed in olfactory neuroephithelium but not in six other tissues tested. Moreover, within the olfactory epithelium, Golf alpha appears to be expressed only by the sensory neurons. Specific antisera were used to localize Golf alpha protein to the sensory apparatus of the receptor neurons. Golf alpha shares extensive amino acid identity (88 percent) with the stimulatory G protein, Gs alpha. The expression of Golf alpha in S49 cyc- kin- cells, a line deficient in endogenous stimulatory G proteins, demonstrates its capacity to stimulate adenylate cyclase in a heterologous system.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Jones, D T -- Reed, R R -- New York, N.Y. -- Science. 1989 May 19;244(4906):790-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Howard Hughes Medical Institute, Department of Molecular Biology and Genetic Johns Hopkins School of Medicine, Baltimore, MD 21205.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2499043" target="_blank"〉PubMed〈/a〉

    Description: During sporulation in Bacillus subtilis, expression of developmental genes spoIVCB and cotD is induced in the mother cell compartment of the sporangium at morphological stages IV and V, respectively. A 27-kilodalton RNA polymerase sigma factor called sigma K (or sigma 27) has been found that causes weak transcription of spoIVCB and strong transcription of cotD. A 14-kD protein was also discovered that changes the specificity of sigma K-containing RNA polymerase, greatly stimulating spoIVCB transcription and markedly repressing cotD transcription. Both sigma K and the 14-kD protein are products of genes known to be required for expression of specific genes in the mother cell. Thus, sigma K directs gene expression in the mother cell and it is proposed that inactivation or sequestering of the 14-kD protein switches the temporal pattern of gene expression during the transition from stages IV to V of development.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kroos, L -- Kunkel, B -- Losick, R -- GM18568/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1989 Jan 27;243(4890):526-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Cellular and Developmental Biology, Harvard University, Cambridge, Massachusetts 02138.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2492118" target="_blank"〉PubMed〈/a〉

    Description: Quiescent T cells can be induced to express many genes by mitogen or antigen stimulation. The messenger RNAs of some of these genes undergo relatively rapid degradation compared to messenger RNAs from constitutively expressed genes. A T cell activation pathway that specifically regulates the stability of messenger RNAs for the lymphokines interleukin-2, interferon-gamma, tumor necrosis factor-alpha, and granulocyte-macrophage colony-stimulating factor is induced by stimulation of the CD28 surface molecule. This pathway does not directly affect the steady-state messenger RNA level, transcription, or messenger RNA half-life of other T cell activation genes, including c-myc, c-fos, IL-2 receptor, and the 4F2HC surface antigen. These data show that stimuli received at the cell surface can alter gene expression by inducing specific changes in messenger RNA degradation.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lindstein, T -- June, C H -- Ledbetter, J A -- Stella, G -- Thompson, C B -- New York, N.Y. -- Science. 1989 Apr 21;244(4902):339-43.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Howard Hughes Medical Institute, University of Michigan, Ann Arbor 48109.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2540528" target="_blank"〉PubMed〈/a〉

The complementary DNA sequence of KGF demonstrates that it is a member of the fibroblast growth factor family. The KGF transcript was present in stromal cells derived from epithelial tissues. By comparison with the expression of other epithelial cell mitogens, only KGF, among known human growth factors, has the properties of a stromal mediator of epithelial cell proliferation.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Finch, P W -- Rubin, J S -- Miki, T -- Ron, D -- Aaronson, S A -- New York, N.Y. -- Science. 1989 Aug 18;245(4919):752-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratory of Cellular and Molecular Biology, National Cancer Institute, Bethesda, MD 20892.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2475908" target="_blank"〉PubMed〈/a〉

    Description: The biological effects of ras oncogene activation in B cells were studied by using amphotropic retroviral vectors to introduce H- or N-ras oncogenes into human B lymphoblasts immortalized by Epstein-Barr virus. Expression of both H- and N-ras oncogenes led to malignant transformation of these cells, as shown by clonogenicity in semisolid media and tumorigenicity in immunodeficient mice. In addition, terminal differentiation into plasma cells was detectable as specific changes in morphology, immunoglobulin secretion, and cell surface antigen expression. This combined effect, promoting growth and differentiation in human lymphoblasts, represents a novel biological action of ras oncogenes and has implications for the pathogenesis of terminally differentiated B-lymphoid malignancies such as multiple myeloma.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Seremetis, S -- Inghirami, G -- Ferrero, D -- Newcomb, E W -- Knowles, D M -- Dotto, G P -- Dalla-Favera, R -- CA-37165/CA/NCI NIH HHS/ -- CA49236/CA/NCI NIH HHS/ -- EY 06337/EY/NEI NIH HHS/ -- New York, N.Y. -- Science. 1989 Feb 3;243(4891):660-3.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Pathology, New York University, NY 10016.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2536954" target="_blank"〉PubMed〈/a〉

    Description: Parasitic protozoans and helminths pose considerable medical as well as scientific challenges. Investigations of the complex and very different life cycles of these organisms, their adaptation to the obligate parasitic mode of life, and their ability to face the hostile host environment have resulted in many exciting discoveries. Invasion of host erythrocytes by plasmodial sporozoites and intact skin by schistosomal cercariae are outlined as examples of the elaborate mechanisms of parasitism. Isolation and characterization of single protective antigens or subunit vaccines from these two organisms are examined as models for vaccine development. Finally, developments in exploring gene regulation in protozoans and free and parasitic nematodes are briefly outlined.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Mahmoud, A A -- New York, N.Y. -- Science. 1989 Nov 24;246(4933):1015-22.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Medicine, Case Western Reserve University School of Medicine, Cleveland, OH 44106.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2686024" target="_blank"〉PubMed〈/a〉

    Description: Mice transgenic for a hybrid gene containing the liver promoter of the mouse amylase gene (Amy-1a) fused to the SV40 tumor antigen coding region unexpected developed malignant brown adipose tissue tumors (malignant hibernomas). Expression of the alpha-amylase gene had previously been thought to be confined to the liver parotid, and pancreas; however, analysis of white and brown adipose tissue from nontransgenic mice revealed expression of the endogenous Amy-1a gene in these tissues. Gene constructs driven by the Amy-1a liver promoter thus provide a means of targeting gene expression to the adipocyte cell lineage in transgenic mice. Moreover the high frequency of metastases in the liver, lungs, spleen, heart, and adrenals of these mice provides an experimental system in which to study the development of disseminated malignancy.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Fox, N -- Crooke, R -- Hwang, L H -- Schibler, U -- Knowles, B B -- Solter, D -- CA-10815/CA/NCI NIH HHS/ -- CA-18470/CA/NCI NIH HHS/ -- CA-21124/CA/NCI NIH HHS/ -- etc. -- New York, N.Y. -- Science. 1989 Apr 28;244(4903):460-3.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Wistar Institute, Philadelphia, PA 19104.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2785714" target="_blank"〉PubMed〈/a〉

    Description: Promonocytic (U1) and T lymphocytic (ACH-2) cell lines chronically infected with human immunodeficiency virus type 1 (HIV-1) constitutively express low levels of virus, but expression can be induced by phorbol esters and cytokines. Whereas ACH-2 cells produce infectious virions, U1 cells produce defective, noninfectious particles. Although 3'-azido-3'-deoxythimidine (AZT) prevented acute HIV infection of susceptible cells, it did not prevent the induction of HIV expression in the infected cell lines. In contrast, interferon alpha (IFN-alpha) inhibited the release of reverse transcriptase and viral antigens into the culture supernatant after phorbol ester stimulation of both cell lines. Further, IFN-alpha suppressed the production or release (or both) of whole HIV virions, but had no effect on the amount of cell-associated viral proteins. Also, after phorbol ester stimulation of ACH-2 cells, IFN-alpha reduced the number of infectious viral particles secreted into the culture supernatant, but had no effect on the infectivity of cell-associated virus. These findings lend support to the combined use of antiviral agents that have action at both the early (AZT) and the late (IFN-alpha) stages of HIV replication.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Poli, G -- Orenstein, J M -- Kinter, A -- Folks, T M -- Fauci, A S -- New York, N.Y. -- Science. 1989 May 5;244(4904):575-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratory of Immunoregulation, National Institute of Allergy and Infectious Diseases, Bethesda, MD 20892.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2470148" target="_blank"〉PubMed〈/a〉

    Description: Specialized regions of muscle fibers may result from differential gene expression within a single fiber. In order to investigate the range of action of individual nuclei in multinucleated myotubes, C2 myoblasts were transfected to obtain stable cell lines that express a reporter protein that is targeted to the nucleus. Hybrid myotubes were then formed containing one or a few transfected nuclei as well as a large number of nuclei from the parental strain. In order to determine how far the products of a single nucleus extend, transfected nuclei were labeled with [3H]thymidine before fusion and the myotubes were stained to identify the reporter protein. In such myotubes the fusion protein was not confined to its nucleus of origin, but was restricted to nearby nuclei.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ralston, E -- Hall, Z W -- NS 20107/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 1989 Jun 2;244(4908):1066-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Physiology, School of Medicine, University of California, San Francisco 94143-0444.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2543074" target="_blank"〉PubMed〈/a〉

    Description: Adipsin is a serine protease that is secreted by adipocytes into the bloodstream; it is deficient in several animal models of obesity, representing a striking example of defective gene expression in this disorder. Recombinant mouse adipsin was purified and its biochemical and enzymatic properties were studied in order to elucidate the function of this protein. Activated adipsin has little or no proteolytic activity toward most substrates but has the same activity as human complement factor D, cleaving complement factor B when it is complexed with activated complement component C3. Like authentic factor D, adipsin can activate the alternative pathway of complement, resulting in red blood cell lysis. Decreased (58 to 80 percent) complement factor D activity, relative to lean controls, was observed as a common feature of several experimental models of obesity, including the ob/ob, db/db, and monosodium glutamate (MSG)-injected mouse and the fa/fa rat. These results suggest that adipsin and the alternative pathway of complement may play an unexpected but important role in the regulation of systemic energy balance in vivo.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Rosen, B S -- Cook, K S -- Yaglom, J -- Groves, D L -- Volanakis, J E -- Damm, D -- White, T -- Spiegelman, B M -- DK31403/DK/NIDDK NIH HHS/ -- DK34605/DK/NIDDK NIH HHS/ -- New York, N.Y. -- Science. 1989 Jun 23;244(4911):1483-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Dana-Farber Cancer Institute, Boston, MA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2734615" target="_blank"〉PubMed〈/a〉

    Description: In Drosophila, five "terminal" polarity genes must be active in females in order for them to produce embryos with normal anterior and posterior ends. Hypoactivity mutations in one such gene, torso, result in the loss of the most posterior domain of fushi tarazu expression and the terminal cuticular structures. In contrast, a torso hyperactivity mutation causes the loss of central fushi tarazu expression and central cuticular structures. Cytoplasmic leakage, transplantation, and temperature-shift experiments suggest that the latter effect is caused by abnormal persistence of the torso product in the central region of the embryo during early development. Thus, the amount and timing of torso activity is key to distinguishing the central and terminal regions of the embryo. Mutations in the tailless terminal gene act as dominant maternal suppressors of the hyperactive torso allele, indicating that the torso product acts through, or in concert with, the tailless product.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Strecker, T R -- Halsell, S R -- Fisher, W W -- Lipshitz, H D -- GM07616/GM/NIGMS NIH HHS/ -- HD23099/HD/NICHD NIH HHS/ -- New York, N.Y. -- Science. 1989 Feb 24;243(4894 Pt 1):1062-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Division of Biology, California Institute of Technology, Pasadena 91125.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2922596" target="_blank"〉PubMed〈/a〉

    Description: T cell receptors are the antigen-recognizing elements found on the effector cells of the immune system. Two isotypes have been discovered, TCR-gamma delta and TCR-alpha beta, which appear in that order during ontogeny. The maturation of prothymocytes that colonize the thymic rudiment at defined gestational stages occurs principally within the thymus, although some evidence for extrathymic maturation also exists. The maturation process includes the rearrangement and expression of the T cell receptor genes. Determination of these mechanisms, the lineages of the cells, and the subsequent thymic selection that results in self-tolerance is the central problem in developmental immunology and is important for the understanding of autoimmune diseases.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Strominger, J L -- New York, N.Y. -- Science. 1989 May 26;244(4907):943-50.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biochemistry and Molecular Biology, Harvard University, Cambridge, MA 02138.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2658058" target="_blank"〉PubMed〈/a〉

    Description: Current therapies for most human genetic diseases are inadequate. In response to the need for effective treatments, modern molecular genetics is providing tools for an unprecedented new approach to disease treatment through an attack directly on mutant genes. Recent results with several target organs and gene transfer techniques have led to broad medical and scientific acceptance of the feasibility of this "gene therapy" concept for disorders of the bone marrow, liver, and central nervous system; some kinds of cancer; and deficiencies of circulating enzymes, hormones, and coagulation factors. The most well-developed models involve alteration of mutant target genes by gene transfer with recombinant pathogenic viruses in order to express new genetic information and to correct disease phenotypes--the conversion of the swords of pathology into the plowshares of therapy.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Friedmann, T -- New York, N.Y. -- Science. 1989 Jun 16;244(4910):1275-81.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Pediatrics, School of Medicine, University of California, San Diego, La Jolla 92093.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2660259" target="_blank"〉PubMed〈/a〉

    Description: Interleukin-2 (IL-2) binds to two distinct receptor molecules, the IL-2 receptor alpha (IL-2R alpha, p55) chain and the newly identified IL-2 receptor beta (IL-2R beta, p70-75) chain. The cDNA encoding the human IL-2R beta chain has now been isolated. The overall primary structure of the IL-2R beta chain shows no apparent homology to other known receptors. Unlike the IL-2R alpha chain, the IL-2R beta chain has a large cytoplasmic region in which a functional domain (or domains) mediating an intracellular signal transduction pathway (or pathways) may be embodied. The cDNA-encoded beta chain binds and internalizes IL-2 when expressed on T lymphoid cells but not fibroblast cells. Furthermore, the cDNA gives rise to the generation of high-affinity IL-2 receptor when co-expressed with the IL-2R alpha chain cDNA.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hatakeyama, M -- Tsudo, M -- Minamoto, S -- Kono, T -- Doi, T -- Miyata, T -- Miyasaka, M -- Taniguchi, T -- New York, N.Y. -- Science. 1989 May 5;244(4904):551-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Institute for Molecular and Cellular Biology, Osaka University, Japan.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2785715" target="_blank"〉PubMed〈/a〉

    Description: A genomic sequence and cloned complementary DNA has been identified for a novel receptor-like gene of the PDGF receptor/CSF1 receptor subfamily (platelet-derived growth factor receptor/colony-stimulating factor type 1 receptor). The gene recognized a 6.4-kilobase transcript that was coexpressed in normal human tissues with the 5.3-kilobase PDGF receptor messenger RNA. Introduction of complementary DNA of the novel gene into COS-1 cells led to expression of proteins that were specifically detected with antiserum directed against a predicted peptide. When the new gene was transfected into COS-1 cells, a characteristic pattern of binding of the PDGF isoforms was observed, which was different from the pattern observed with the known PDGF receptor. Tyrosine phosphorylation of the receptor in response to the PDGF isoforms was also different from the known receptor. The new PDGF receptor gene was localized to chromosome 4q11-4q12. The existence of genes encoding two PDGF receptors that interact in a distinct manner with three different PDGF isoforms likely confers considerable regulatory flexibility in the functional responses to PDGF.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Matsui, T -- Heidaran, M -- Miki, T -- Popescu, N -- La Rochelle, W -- Kraus, M -- Pierce, J -- Aaronson, S -- New York, N.Y. -- Science. 1989 Feb 10;243(4892):800-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratory of Cellular and Molecular Biology, National Cancer Institute, Bethesda, MD 20892.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2536956" target="_blank"〉PubMed〈/a〉

    Description: The cloning of genes encoding mammalian DNA binding transcription factors for RNA polymerase II has provided the opportunity to analyze the structure and function of these proteins. This review summarizes recent studies that define structural domains for DNA binding and transcriptional activation functions in sequence-specific transcription factors. The mechanisms by which these factors may activate transcriptional initiation and by which they may be regulated to achieve differential gene expression are also discussed.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Mitchell, P J -- Tjian, R -- New York, N.Y. -- Science. 1989 Jul 28;245(4916):371-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Howard Hughes Medical Institute, Department of Biochemistry, University of California, Berkeley 94720.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2667136" target="_blank"〉PubMed〈/a〉
