    Trim28 is required for epigenetic stability during mouse oocyte to embryo transition (2012)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2012-03-24
    Description: Phenotypic variability in genetic disease is usually attributed to genetic background variation or environmental influence. Here, we show that deletion of a single gene, Trim28 (Kap1 or Tif1beta), from the maternal germ line alone, on an otherwise identical genetic background, results in severe phenotypic and epigenetic variability that leads to embryonic lethality. We identify early and minute epigenetic variations in blastomeres of the preimplantation embryo of these animals, suggesting that the embryonic lethality may result from the misregulation of genomic imprinting in mice lacking maternal Trim28. Our results reveal the long-range effects of a maternal gene deletion on epigenetic memory and illustrate the delicate equilibrium of maternal and zygotic factors during nuclear reprogramming.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Messerschmidt, Daniel M -- de Vries, Wilhelmine -- Ito, Mitsuteru -- Solter, Davor -- Ferguson-Smith, Anne -- Knowles, Barbara B -- 079249/Wellcome Trust/United Kingdom -- 095606/Wellcome Trust/United Kingdom -- MR/J001597/1/Medical Research Council/United Kingdom -- Wellcome Trust/United Kingdom -- New York, N.Y. -- Science. 2012 Mar 23;335(6075):1499-502. doi: 10.1126/science.1216154.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Mammalian Development Group, Institute of Medical Biology, Singapore.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/22442485" target="_blank"〉PubMed〈/a〉

    Ancestral developmental potential facilitates parallel evolution in ants (2012)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2012-01-10
    Description: Complex worker caste systems have contributed to the evolutionary success of advanced ant societies; however, little is known about the developmental processes underlying their origin and evolution. We combined hormonal manipulation, gene expression, and phylogenetic analyses with field observations to understand how novel worker subcastes evolve. We uncovered an ancestral developmental potential to produce a "supersoldier" subcaste that has been actualized at least two times independently in the hyperdiverse ant genus Pheidole. This potential has been retained and can be environmentally induced throughout the genus. Therefore, the retention and induction of this potential have facilitated the parallel evolution of supersoldiers through a process known as genetic accommodation. The recurrent induction of ancestral developmental potential may facilitate the adaptive and parallel evolution of phenotypes.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Rajakumar, Rajendhran -- San Mauro, Diego -- Dijkstra, Michiel B -- Huang, Ming H -- Wheeler, Diana E -- Hiou-Tim, Francois -- Khila, Abderrahman -- Cournoyea, Michael -- Abouheif, Ehab -- New York, N.Y. -- Science. 2012 Jan 6;335(6064):79-82. doi: 10.1126/science.1211451.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biology, McGill University, 1205 Avenue Dr. Penfield, Montreal, Quebec, Canada, H3A 1B1.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/22223805" target="_blank"〉PubMed〈/a〉

    Rapamycin-induced insulin resistance is mediated by mTORC2 loss and uncoupled from longevity (2012)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2012-03-31
    Description: Rapamycin, an inhibitor of mechanistic target of rapamycin complex 1 (mTORC1), extends the life spans of yeast, flies, and mice. Calorie restriction, which increases life span and insulin sensitivity, is proposed to function by inhibition of mTORC1, yet paradoxically, chronic administration of rapamycin substantially impairs glucose tolerance and insulin action. We demonstrate that rapamycin disrupted a second mTOR complex, mTORC2, in vivo and that mTORC2 was required for the insulin-mediated suppression of hepatic gluconeogenesis. Further, decreased mTORC1 signaling was sufficient to extend life span independently from changes in glucose homeostasis, as female mice heterozygous for both mTOR and mLST8 exhibited decreased mTORC1 activity and extended life span but had normal glucose tolerance and insulin sensitivity. Thus, mTORC2 disruption is an important mediator of the effects of rapamycin in vivo.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3324089/" 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/PMC3324089/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lamming, Dudley W -- Ye, Lan -- Katajisto, Pekka -- Goncalves, Marcus D -- Saitoh, Maki -- Stevens, Deanna M -- Davis, James G -- Salmon, Adam B -- Richardson, Arlan -- Ahima, Rexford S -- Guertin, David A -- Sabatini, David M -- Baur, Joseph A -- 1F32AG032833-01A1/AG/NIA NIH HHS/ -- CA129105/CA/NCI NIH HHS/ -- F32 AG032833/AG/NIA NIH HHS/ -- P30DK19525/DK/NIDDK NIH HHS/ -- R01 CA129105/CA/NCI NIH HHS/ -- R01 CA129105-05/CA/NCI NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2012 Mar 30;335(6076):1638-43. doi: 10.1126/science.1215135.〈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/22461615" target="_blank"〉PubMed〈/a〉

    Hepcidin and the iron-infection axis (2012)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2012-11-10
    Description: Iron lies at the center of a battle for nutritional resource between higher organisms and their microbial pathogens. The iron status of the human host affects the pathogenicity of numerous infections including malaria, HIV-1, and tuberculosis. Hepcidin, an antimicrobial-like peptide hormone, has emerged as the master regulator of iron metabolism. Hepcidin controls the absorption of dietary iron and the distribution of iron among cell types in the body, and its synthesis is regulated by both iron and innate immunity. We describe how hepcidin integrates signals from diverse physiological inputs, forming a key molecular bridge between iron trafficking and response to infection.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Drakesmith, Hal -- Prentice, Andrew M -- G0700844/Medical Research Council/United Kingdom -- G0901149/Medical Research Council/United Kingdom -- MC-A760-5QX00/Medical Research Council/United Kingdom -- MC_U123292699/Medical Research Council/United Kingdom -- MC_U123292700/Medical Research Council/United Kingdom -- MC_U123292701/Medical Research Council/United Kingdom -- New York, N.Y. -- Science. 2012 Nov 9;338(6108):768-72. doi: 10.1126/science.1224577.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Molecular Immunology Group and Medical Research Council (MRC) Human Immunology Unit, MRC Weatherall Institute of Molecular Medicine, University of Oxford, John Radcliffe Hospital, Oxford, UK. alexander.drakesmith@ndm.ox.ac.uk〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/23139325" target="_blank"〉PubMed〈/a〉

    Erasure of a spinal memory trace of pain by a brief, high-dose opioid administration (2012)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2012-01-17
    Description: Painful stimuli activate nociceptive C fibers and induce synaptic long-term potentiation (LTP) at their spinal terminals. LTP at C-fiber synapses represents a cellular model for pain amplification (hyperalgesia) and for a memory trace of pain. mu-Opioid receptor agonists exert a powerful but reversible depression at C-fiber synapses that renders the continuous application of low opioid doses the gold standard in pain therapy. We discovered that brief application of a high opioid dose reversed various forms of activity-dependent LTP at C-fiber synapses. Depotentiation involved Ca(2+)-dependent signaling and normalization of the phosphorylation state of alpha-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid receptors. This also reversed hyperalgesia in behaving animals. Opioids thus not only temporarily dampen pain but may also erase a spinal memory trace of pain.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Drdla-Schutting, Ruth -- Benrath, Justus -- Wunderbaldinger, Gabriele -- Sandkuhler, Jurgen -- New York, N.Y. -- Science. 2012 Jan 13;335(6065):235-8. doi: 10.1126/science.1211726.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Neurophysiology, Center for Brain Research, Medical University of Vienna, A-1090 Vienna, Austria.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/22246779" target="_blank"〉PubMed〈/a〉

    Bateman in nature: predation on offspring reduces the potential for sexual selection (2012)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2012-11-10
    Description: Sexual selection is driven by competition for mates, and the advantage of a competitor is determined by the number of offspring it produces. Early experiments by Angus Bateman characterized this interaction, and the quantitative relationship between a male's number of mates and number of offspring is known as the Bateman slope. Sexual dimorphism, one of the most obvious results of sexual selection, largely requires a positive Bateman relationship, and the slope provides an estimate of the potential for sexual selection. However, natural selection from the environment can also influence male success, as can random effects, and some have argued for inclusion of the latter in calculations of mate success. Data from pronghorn (Antilocapra americana) reveal the presence of a positive Bateman slope in each year of a 10-year study. We found no evidence that random effects skewed male mating success; however, substantial yearly variation in the Bateman slope due to predation on fawns was evident. These results support the validity of the Bateman relationship, yet they also demonstrate that environmental or extrinsic influences can limit the potential for sexual selection.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Byers, John -- Dunn, Stacey -- New York, N.Y. -- Science. 2012 Nov 9;338(6108):802-4. doi: 10.1126/science.1224660.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biological Sciences, University of Idaho, Moscow, ID 83844-3051, USA. jbyers@uidaho.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/23139332" target="_blank"〉PubMed〈/a〉

    Interleukin-22 drives endogenous thymic regeneration in mice (2012)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2012-03-03
    Description: Endogenous thymic regeneration is a crucial function that allows for renewal of immune competence after stress, infection, or immunodepletion. However, the mechanisms governing this regeneration remain poorly understood. We detail such a mechanism, centered on interleukin-22 (IL-22) and triggered by the depletion of CD4(+)CD8(+) double-positive thymocytes. Intrathymic levels of IL-22 were increased after thymic insult, and thymic recovery was impaired in IL-22-deficient mice. IL-22, which signaled through thymic epithelial cells and promoted their proliferation and survival, was up-regulated by radio-resistant RORgamma(t)(+)CCR6(+)NKp46(-) lymphoid tissue inducer cells after thymic injury in an IL-23-dependent manner. Administration of IL-22 enhanced thymic recovery after total body irradiation. These studies reveal mechanisms of endogenous thymic repair and offer innovative regenerative strategies for improving immune competence.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3616391/" 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/PMC3616391/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Dudakov, Jarrod A -- Hanash, Alan M -- Jenq, Robert R -- Young, Lauren F -- Ghosh, Arnab -- Singer, Natalie V -- West, Mallory L -- Smith, Odette M -- Holland, Amanda M -- Tsai, Jennifer J -- Boyd, Richard L -- van den Brink, Marcel R M -- AI080455/AI/NIAID NIH HHS/ -- CA107096/CA/NCI NIH HHS/ -- HL069929/HL/NHLBI NIH HHS/ -- HL095075/HL/NHLBI NIH HHS/ -- R01 AI080455/AI/NIAID NIH HHS/ -- R01 CA107096/CA/NCI NIH HHS/ -- R01 HL069929/HL/NHLBI NIH HHS/ -- R01 HL095075/HL/NHLBI NIH HHS/ -- T32 CA009207/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 2012 Apr 6;336(6077):91-5. doi: 10.1126/science.1218004.

    Evolution and functional impact of rare coding variation from deep sequencing of human exomes (2012)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2012-05-19
    Description: As a first step toward understanding how rare variants contribute to risk for complex diseases, we sequenced 15,585 human protein-coding genes to an average median depth of 111x in 2440 individuals of European (n = 1351) and African (n = 1088) ancestry. We identified over 500,000 single-nucleotide variants (SNVs), the majority of which were rare (86% with a minor allele frequency less than 0.5%), previously unknown (82%), and population-specific (82%). On average, 2.3% of the 13,595 SNVs each person carried were predicted to affect protein function of ~313 genes per genome, and ~95.7% of SNVs predicted to be functionally important were rare. This excess of rare functional variants is due to the combined effects of explosive, recent accelerated population growth and weak purifying selection. Furthermore, we show that large sample sizes will be required to associate rare variants with complex traits.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3708544/" 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/PMC3708544/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Tennessen, Jacob A -- Bigham, Abigail W -- O'Connor, Timothy D -- Fu, Wenqing -- Kenny, Eimear E -- Gravel, Simon -- McGee, Sean -- Do, Ron -- Liu, Xiaoming -- Jun, Goo -- Kang, Hyun Min -- Jordan, Daniel -- Leal, Suzanne M -- Gabriel, Stacey -- Rieder, Mark J -- Abecasis, Goncalo -- Altshuler, David -- Nickerson, Deborah A -- Boerwinkle, Eric -- Sunyaev, Shamil -- Bustamante, Carlos D -- Bamshad, Michael J -- Akey, Joshua M -- Broad GO -- Seattle GO -- NHLBI Exome Sequencing Project -- R01 HG003229/HG/NHGRI NIH HHS/ -- RC2 HL-102923/HL/NHLBI NIH HHS/ -- RC2 HL-102924/HL/NHLBI NIH HHS/ -- RC2 HL-102925/HL/NHLBI NIH HHS/ -- RC2 HL-102926/HL/NHLBI NIH HHS/ -- RC2 HL-103010/HL/NHLBI NIH HHS/ -- RC2 HL102926/HL/NHLBI NIH HHS/ -- New York, N.Y. -- Science. 2012 Jul 6;337(6090):64-9. doi: 10.1126/science.1219240.

    Ecological context influences epidemic size and parasite-driven evolution (2012)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2012-03-31
    Description: The occurrence and magnitude of disease outbreaks can strongly influence host evolution. In particular, when hosts face a resistance-fecundity trade-off, they might evolve increased resistance to infection during larger epidemics but increased susceptibility during smaller ones. We tested this theoretical prediction by using a zooplankton-yeast host-parasite system in which ecological factors determine epidemic size. Lakes with high productivity and low predation pressure had large yeast epidemics; during these outbreaks, hosts became more resistant to infection. However, with low productivity and high predation, epidemics remained small and hosts evolved increased susceptibility. Thus, by modulating disease outbreaks, ecological context (productivity and predation) shaped host evolution during epidemics. Consequently, anthropogenic alteration of productivity and predation might strongly influence both ecological and evolutionary outcomes of disease.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Duffy, Meghan A -- Ochs, Jessica Housley -- Penczykowski, Rachel M -- Civitello, David J -- Klausmeier, Christopher A -- Hall, Spencer R -- New York, N.Y. -- Science. 2012 Mar 30;335(6076):1636-8. doi: 10.1126/science.1215429.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉School of Biology, Georgia Institute of Technology, Atlanta, GA 30332-0230, USA. duffy@gatech.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/22461614" target="_blank"〉PubMed〈/a〉

    A Bruce effect in wild geladas (2012)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2012-03-01
    Description: Female rodents are known to terminate pregnancies after exposure to unfamiliar males ("Bruce effect"). Although laboratory support abounds, direct evidence for a Bruce effect under natural conditions is lacking. Here, we report a strong Bruce effect in a wild primate, the gelada (Theropithecus gelada). Female geladas terminate 80% of pregnancies in the weeks after a dominant male is replaced. Further, data on interbirth intervals suggest that pregnancy termination offers fitness benefits for females whose offspring would otherwise be susceptible to infanticide. Taken together, data support the hypothesis that the Bruce effect can be an adaptive strategy for females.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Roberts, Eila K -- Lu, Amy -- Bergman, Thore J -- Beehner, Jacinta C -- New York, N.Y. -- Science. 2012 Mar 9;335(6073):1222-5. doi: 10.1126/science.1213600.

    Wnt5a potentiates TGF-beta signaling to promote colonic crypt regeneration after tissue injury (2012)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2012-09-08
    Description: Reestablishing homeostasis after tissue damage depends on the proper organization of stem cells and their progeny, though the repair mechanisms are unclear. The mammalian intestinal epithelium is well suited to approach this problem, as it is composed of well-delineated units called crypts of Lieberkuhn. We found that Wnt5a, a noncanonical Wnt ligand, was required for crypt regeneration after injury in mice. Unlike controls, Wnt5a-deficient mice maintained an expanded population of proliferative epithelial cells in the wound. We used an in vitro system to enrich for intestinal epithelial stem cells to discover that Wnt5a inhibited proliferation of these cells. Surprisingly, the effects of Wnt5a were mediated by activation of transforming growth factor-beta (TGF-beta) signaling. These findings suggest a Wnt5a-dependent mechanism for forming new crypt units to reestablish homeostasis.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3706630/" 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/PMC3706630/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Miyoshi, Hiroyuki -- Ajima, Rieko -- Luo, Christine T -- Yamaguchi, Terry P -- Stappenbeck, Thaddeus S -- 5T35DK074375/DK/NIDDK NIH HHS/ -- DK90251/DK/NIDDK NIH HHS/ -- P30-DK52574/DK/NIDDK NIH HHS/ -- R01 DK071619/DK/NIDDK NIH HHS/ -- Intramural NIH HHS/ -- New York, N.Y. -- Science. 2012 Oct 5;338(6103):108-13. doi: 10.1126/science.1223821.

    Pheromonal induction of spatial learning in mice (2012)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2012-12-15
    Description: Many mammals use scent marking for sexual and competitive advertisement, but little is known about the mechanism by which scents are used to locate mates and competitors. We show that darcin, an involatile protein sex pheromone in male mouse urine, can rapidly condition preference for its remembered location among females and competitor males so that animals prefer to spend time in the site even when scent is absent. Learned spatial preference is conditioned through contact with darcin in a single trial and remembered for approximately 14 days. This pheromone-induced learning allows animals to relocate sites of particular social relevance and provides proof that pheromones such as darcin can be highly potent stimuli for social learning.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Roberts, Sarah A -- Davidson, Amanda J -- McLean, Lynn -- Beynon, Robert J -- Hurst, Jane L -- BB/J002631/1/Biotechnology and Biological Sciences Research Council/United Kingdom -- BBC503897/Biotechnology and Biological Sciences Research Council/United Kingdom -- New York, N.Y. -- Science. 2012 Dec 14;338(6113):1462-5. doi: 10.1126/science.1225638.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Mammalian Behaviour and Evolution Group, Institute of Integrative Biology, University of Liverpool, Leahurst Campus, Neston CH64 7TE, UK.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/23239735" target="_blank"〉PubMed〈/a〉

    Functional supramolecular polymers (2012)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2012-02-22
    Description: Supramolecular polymers can be random and entangled coils with the mechanical properties of plastics and elastomers, but with great capacity for processability, recycling, and self-healing due to their reversible monomer-to-polymer transitions. At the other extreme, supramolecular polymers can be formed by self-assembly among designed subunits to yield shape-persistent and highly ordered filaments. The use of strong and directional interactions among molecular subunits can achieve not only rich dynamic behavior but also high degrees of internal order that are not known in ordinary polymers. They can resemble, for example, the ordered and dynamic one-dimensional supramolecular assemblies of the cell cytoskeleton and possess useful biological and electronic functions.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3291483/" 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/PMC3291483/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Aida, T -- Meijer, E W -- Stupp, S I -- 2R01DE015920-06/DE/NIDCR NIH HHS/ -- 2R01EB003806-06A2/EB/NIBIB NIH HHS/ -- R01 DE015920/DE/NIDCR NIH HHS/ -- R01 DE015920-06/DE/NIDCR NIH HHS/ -- R01 EB003806/EB/NIBIB NIH HHS/ -- R01 EB003806-06A2/EB/NIBIB NIH HHS/ -- New York, N.Y. -- Science. 2012 Feb 17;335(6070):813-7. doi: 10.1126/science.1205962.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Chemistry and Biotechnology, School of Engineering, University of Tokyo, Tokyo, Japan.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/22344437" target="_blank"〉PubMed〈/a〉

    Publication Date: 2012-04-14
    Description: Computational approaches are breaking new ground in understanding how embryos form. Here, we discuss recent studies that couple precise measurements in the embryo with appropriately matched modeling and computational methods to investigate classic embryonic patterning strategies. We include signaling gradients, activator-inhibitor systems, and coupled oscillators, as well as emerging paradigms such as tissue deformation. Parallel progress in theory and experiment will play an increasingly central role in deciphering developmental patterning.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Morelli, Luis G -- Uriu, Koichiro -- Ares, Saul -- Oates, Andrew C -- New York, N.Y. -- Science. 2012 Apr 13;336(6078):187-91. doi: 10.1126/science.1215478.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Max Planck Institute of Molecular Cell Biology and Genetics, Dresden, Germany.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/22499940" target="_blank"〉PubMed〈/a〉

    Asymmetric division of Drosophila male germline stem cell shows asymmetric histone distribution (2012)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2012-11-03
    Description: Stem cells can self-renew and generate differentiating daughter cells. It is not known whether these cells maintain their epigenetic information during asymmetric division. Using a dual-color method to differentially label "old" versus "new" histones in Drosophila male germline stem cells (GSCs), we show that preexisting canonical H3, but not variant H3.3, histones are selectively segregated to the GSC, whereas newly synthesized histones incorporated during DNA replication are enriched in the differentiating daughter cell. The asymmetric histone distribution occurs in GSCs but not in symmetrically dividing progenitor cells. Furthermore, if GSCs are genetically manipulated to divide symmetrically, this asymmetric mode is lost. This work suggests that stem cells retain preexisting canonical histones during asymmetric cell divisions, probably as a mechanism to maintain their unique molecular properties.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3532436/" 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/PMC3532436/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Tran, Vuong -- Lim, Cindy -- Xie, Jing -- Chen, Xin -- R01 HD065816/HD/NICHD NIH HHS/ -- R01HD065816/HD/NICHD NIH HHS/ -- R21 HD065089/HD/NICHD NIH HHS/ -- R21HD065089/HD/NICHD NIH HHS/ -- T32 GM007231/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2012 Nov 2;338(6107):679-82. doi: 10.1126/science.1226028.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biology, Johns Hopkins University, Baltimore, MD 21218, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/23118191" target="_blank"〉PubMed〈/a〉

    Description: The composition and activity of the gut microbiota codevelop with the host from birth and is subject to a complex interplay that depends on the host genome, nutrition, and life-style. The gut microbiota is involved in the regulation of multiple host metabolic pathways, giving rise to interactive host-microbiota metabolic, signaling, and immune-inflammatory axes that physiologically connect the gut, liver, muscle, and brain. A deeper understanding of these axes is a prerequisite for optimizing therapeutic strategies to manipulate the gut microbiota to combat disease and improve health.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Nicholson, Jeremy K -- Holmes, Elaine -- Kinross, James -- Burcelin, Remy -- Gibson, Glenn -- Jia, Wei -- Pettersson, Sven -- R01AA020212/AA/NIAAA NIH HHS/ -- Biotechnology and Biological Sciences Research Council/United Kingdom -- Medical Research Council/United Kingdom -- Wellcome Trust/United Kingdom -- New York, N.Y. -- Science. 2012 Jun 8;336(6086):1262-7. doi: 10.1126/science.1223813.

    Description: Although people often tend to consider themselves and others as unique individuals, there are many situations in which they think, feel, and act primarily as group members. This can bring out the best in them, as when they are inspired to help fellow citizens in need, or the worst, as when they show hostility against others simply because they represent another religious or ethnic group. Understanding when and why the group self becomes more important than the individual self, and how this affects people's thoughts, feelings, and behaviors, can help to prevent and redirect unwelcome aspects of human behavior by addressing them at the appropriate level of self.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ellemers, Naomi -- New York, N.Y. -- Science. 2012 May 18;336(6083):848-52. doi: 10.1126/science.1220987.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Institute for Psychological Research, Department of Social and Organizational Psychology, Leiden University, Post Office Box 9555, 2300 RB Leiden, Netherlands.

    Body cues, not facial expressions, discriminate between intense positive and negative emotions (2012)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2012-12-01
    Description: The distinction between positive and negative emotions is fundamental in emotion models. Intriguingly, neurobiological work suggests shared mechanisms across positive and negative emotions. We tested whether similar overlap occurs in real-life facial expressions. During peak intensities of emotion, positive and negative situations were successfully discriminated from isolated bodies but not faces. Nevertheless, viewers perceived illusory positivity or negativity in the nondiagnostic faces when seen with bodies. To reveal the underlying mechanisms, we created compounds of intense negative faces combined with positive bodies, and vice versa. Perceived affect and mimicry of the faces shifted systematically as a function of their contextual body emotion. These findings challenge standard models of emotion expression and highlight the role of the body in expressing and perceiving emotions.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Aviezer, Hillel -- Trope, Yaacov -- Todorov, Alexander -- New York, N.Y. -- Science. 2012 Nov 30;338(6111):1225-9. doi: 10.1126/science.1224313.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Psychology, Princeton University, Princeton, NJ 08540, USA. haviezer@mail.huji.ac.il〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/23197536" target="_blank"〉PubMed〈/a〉

    Publication Date: 2012-07-28
    Description: In order to understand the nervous system, it is necessary to know the synaptic connections between the neurons, yet to date, only the wiring diagram of the adult hermaphrodite of the nematode Caenorhabditis elegans has been determined. Here, we present the wiring diagram of the posterior nervous system of the C. elegans adult male, reconstructed from serial electron micrograph sections. This region of the male nervous system contains the sexually dimorphic circuits for mating. The synaptic connections, both chemical and gap junctional, form a neural network with four striking features: multiple, parallel, short synaptic pathways directly connecting sensory neurons to end organs; recurrent and reciprocal connectivity among sensory neurons; modular substructure; and interneurons acting in feedforward loops. These features help to explain how the network robustly and rapidly selects and executes the steps of a behavioral program on the basis of the inputs from multiple sensory neurons.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Jarrell, Travis A -- Wang, Yi -- Bloniarz, Adam E -- Brittin, Christopher A -- Xu, Meng -- Thomson, J Nichol -- Albertson, Donna G -- Hall, David H -- Emmons, Scott W -- OD 010943/OD/NIH HHS/ -- R21MH63223/MH/NIMH NIH HHS/ -- Medical Research Council/United Kingdom -- New York, N.Y. -- Science. 2012 Jul 27;337(6093):437-44. doi: 10.1126/science.1221762.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Genetics, Albert Einstein College of Medicine, 1300 Morris Park Avenue, Bronx, NY 10461, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/22837521" target="_blank"〉PubMed〈/a〉

    Chitin-induced dimerization activates a plant immune receptor (2012)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2012-06-02
    Description: Pattern recognition receptors confer plant resistance to pathogen infection by recognizing the conserved pathogen-associated molecular patterns. The cell surface receptor chitin elicitor receptor kinase 1 of Arabidopsis (AtCERK1) directly binds chitin through its lysine motif (LysM)-containing ectodomain (AtCERK1-ECD) to activate immune responses. The crystal structure that we solved of an AtCERK1-ECD complexed with a chitin pentamer reveals that their interaction is primarily mediated by a LysM and three chitin residues. By acting as a bivalent ligand, a chitin octamer induces AtCERK1-ECD dimerization that is inhibited by shorter chitin oligomers. A mutation attenuating chitin-induced AtCERK1-ECD dimerization or formation of nonproductive AtCERK1 dimer by overexpression of AtCERK1-ECD compromises AtCERK1-mediated signaling in plant cells. Together, our data support the notion that chitin-induced AtCERK1 dimerization is critical for its activation.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Liu, Tingting -- Liu, Zixu -- Song, Chuanjun -- Hu, Yunfei -- Han, Zhifu -- She, Ji -- Fan, Fangfang -- Wang, Jiawei -- Jin, Changwen -- Chang, Junbiao -- Zhou, Jian-Min -- Chai, Jijie -- New York, N.Y. -- Science. 2012 Jun 1;336(6085):1160-4. doi: 10.1126/science.1218867.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Graduate Program in Chinese Academy of Medical Sciences and Peking Union Medical College, Beijing 100730, China.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/22654057" target="_blank"〉PubMed〈/a〉

    The pulvinar regulates information transmission between cortical areas based on attention demands (2012)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2012-08-11
    Description: Selective attention mechanisms route behaviorally relevant information through large-scale cortical networks. Although evidence suggests that populations of cortical neurons synchronize their activity to preferentially transmit information about attentional priorities, it is unclear how cortical synchrony across a network is accomplished. Based on its anatomical connectivity with the cortex, we hypothesized that the pulvinar, a thalamic nucleus, regulates cortical synchrony. We mapped pulvino-cortical networks within the visual system, using diffusion tensor imaging, and simultaneously recorded spikes and field potentials from these interconnected network sites in monkeys performing a visuospatial attention task. The pulvinar synchronized activity between interconnected cortical areas according to attentional allocation, suggesting a critical role for the thalamus not only in attentional selection but more generally in regulating information transmission across the visual cortex.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3714098/" 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/PMC3714098/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Saalmann, Yuri B -- Pinsk, Mark A -- Wang, Liang -- Li, Xin -- Kastner, Sabine -- R01 EY017699/EY/NEI NIH HHS/ -- R21 EY021078/EY/NEI NIH HHS/ -- New York, N.Y. -- Science. 2012 Aug 10;337(6095):753-6. doi: 10.1126/science.1223082.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Princeton Neuroscience Institute, Princeton University, Princeton, NJ 08544, USA. saalmann@princeton.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/22879517" target="_blank"〉PubMed〈/a〉

    Adaptive sleep loss in polygynous pectoral sandpipers (2012)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2012-08-11
    Description: The functions of sleep remain elusive. Extensive evidence suggests that sleep performs restorative processes that sustain waking brain performance. An alternative view proposes that sleep simply enforces adaptive inactivity to conserve energy when activity is unproductive. Under this hypothesis, animals may evolve the ability to dispense with sleep when ecological demands favor wakefulness. Here, we show that male pectoral sandpipers (Calidris melanotos), a polygynous Arctic breeding shorebird, are able to maintain high neurobehavioral performance despite greatly reducing their time spent sleeping during a 3-week period of intense male-male competition for access to fertile females. Males that slept the least sired the most offspring. Our results challenge the view that decreased performance is an inescapable outcome of sleep loss.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lesku, John A -- Rattenborg, Niels C -- Valcu, Mihai -- Vyssotski, Alexei L -- Kuhn, Sylvia -- Kuemmeth, Franz -- Heidrich, Wolfgang -- Kempenaers, Bart -- New York, N.Y. -- Science. 2012 Sep 28;337(6102):1654-8.

    Orbitofrontal cortex supports behavior and learning using inferred but not cached values (2012)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2012-11-20
    Description: Computational and learning theory models propose that behavioral control reflects value that is both cached (computed and stored during previous experience) and inferred (estimated on the fly on the basis of knowledge of the causal structure of the environment). The latter is thought to depend on the orbitofrontal cortex. Yet some accounts propose that the orbitofrontal cortex contributes to behavior by signaling "economic" value, regardless of the associative basis of the information. We found that the orbitofrontal cortex is critical for both value-based behavior and learning when value must be inferred but not when a cached value is sufficient. The orbitofrontal cortex is thus fundamental for accessing model-based representations of the environment to compute value rather than for signaling value per se.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3592380/" 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/PMC3592380/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Jones, Joshua L -- Esber, Guillem R -- McDannald, Michael A -- Gruber, Aaron J -- Hernandez, Alex -- Mirenzi, Aaron -- Schoenbaum, Geoffrey -- F32 DA031517/DA/NIDA NIH HHS/ -- F32-031517/PHS HHS/ -- R01 DA015718/DA/NIDA NIH HHS/ -- R01-DA015718/DA/NIDA NIH HHS/ -- ZIA DA000587-01/Intramural NIH HHS/ -- New York, N.Y. -- Science. 2012 Nov 16;338(6109):953-6. doi: 10.1126/science.1227489.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Anatomy and Neurobiology, University of Maryland School of Medicine, 20 Penn Street, Baltimore, MD 21201, USA. josh.jones@nih.gov〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/23162000" target="_blank"〉PubMed〈/a〉

    Evolution of shape by multiple regulatory changes to a growth gene (2012)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2012-03-01
    Description: The genetic changes responsible for morphological differences between species are largely unidentified. Such changes can involve modifications of growth that are relevant to understanding evolution, development, and disease. We identified a gene that induces male-specific wing size and shape differences between Nasonia wasp species. Fine-scale mapping and in situ hybridization reveal that changes in at least three regions (two strictly in noncoding sequence) around the gene unpaired-like (upd-like) cause changes in spatial and temporal expression of upd-like in the developing wing and corresponding changes in wing width. Upd-like shows homology to the Drosophila unpaired gene, a well-studied signaling protein that regulates cell proliferation and differentiation. Our results indicate how multiple changes in the regulation of upd-like are involved in microevolution of morphological and sex-specific differences between species.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3520604/" 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/PMC3520604/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Loehlin, David W -- Werren, John H -- 5R01 GM070026-04/GM/NIGMS NIH HHS/ -- 5R24 GM084917-04/GM/NIGMS NIH HHS/ -- R01 GM070026/GM/NIGMS NIH HHS/ -- R24 GM084917/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2012 Feb 24;335(6071):943-7. doi: 10.1126/science.1215193.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biology, University of Rochester, Rochester, NY 14627, USA. loehlin@wisc.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/22363002" target="_blank"〉PubMed〈/a〉

    Glucocorticoids can induce PTSD-like memory impairments in mice (2012)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2012-03-01
    Description: Posttraumatic stress disorder (PTSD) is characterized by a hypermnesia of the trauma and by a memory impairment that decreases the ability to restrict fear to the appropriate context. Infusion of glucocorticoids in the hippocampus after fear conditioning induces PTSD-like memory impairments and an altered pattern of neural activation in the hippocampal-amygdalar circuit. Mice become unable to identify the context as the correct predictor of the threat and show fear responses to a discrete cue not predicting the threat in normal conditions. These data demonstrate PTSD-like memory impairments in rodents and identify a potential pathophysiological mechanism of this condition.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kaouane, Nadia -- Porte, Yves -- Vallee, Monique -- Brayda-Bruno, Laurent -- Mons, Nicole -- Calandreau, Ludovic -- Marighetto, Aline -- Piazza, Pier Vincenzo -- Desmedt, Aline -- New York, N.Y. -- Science. 2012 Mar 23;335(6075):1510-3. doi: 10.1126/science.1207615.

    Removal of shelterin reveals the telomere end-protection problem (2012)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2012-05-05
    Description: The telomere end-protection problem is defined by the aggregate of DNA damage signaling and repair pathways that require repression at telomeres. To define the end-protection problem, we removed the whole shelterin complex from mouse telomeres through conditional deletion of TRF1 and TRF2 in nonhomologous end-joining (NHEJ) deficient cells. The data reveal two DNA damage response pathways not previously observed upon deletion of individual shelterin proteins. The shelterin-free telomeres are processed by microhomology-mediated alternative-NHEJ when Ku70/80 is absent and are attacked by nucleolytic degradation in the absence of 53BP1. The data establish that the end-protection problem is specified by six pathways [ATM (ataxia telangiectasia mutated) and ATR (ataxia telangiectasia and Rad3 related) signaling, classical-NHEJ, alt-NHEJ, homologous recombination, and resection] and show how shelterin acts with general DNA damage response factors to solve this problem.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3477646/" 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/PMC3477646/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Sfeir, Agnel -- de Lange, Titia -- AG016642/AG/NIA NIH HHS/ -- GM49046/GM/NIGMS NIH HHS/ -- R01 AG016642/AG/NIA NIH HHS/ -- R01 CA076027/CA/NCI NIH HHS/ -- R37 GM049046/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2012 May 4;336(6081):593-7. doi: 10.1126/science.1218498.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratory for Cell Biology and 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/22556254" target="_blank"〉PubMed〈/a〉

    Network resets in medial prefrontal cortex mark the onset of behavioral uncertainty (2012)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2012-10-09
    Description: Regions within the prefrontal cortex are thought to process beliefs about the world, but little is known about the circuit dynamics underlying the formation and modification of these beliefs. Using a task that permits dissociation between the activity encoding an animal's internal state and that encoding aspects of behavior, we found that transient increases in the volatility of activity in the rat medial prefrontal cortex accompany periods when an animal's belief is modified after an environmental change. Activity across the majority of sampled neurons underwent marked, abrupt, and coordinated changes when prior belief was abandoned in favor of exploration of alternative strategies. These dynamics reflect network switches to a state of instability, which diminishes over the period of exploration as new stable representations are formed.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Karlsson, Mattias P -- Tervo, Dougal G R -- Karpova, Alla Y -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2012 Oct 5;338(6103):135-9. doi: 10.1126/science.1226518.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Janelia Farm Research Campus, Howard Hughes Medical Institute, 19700 Helix Drive, Ashburn, VA 20147, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/23042898" target="_blank"〉PubMed〈/a〉

    Some consequences of having too little (2012)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2012-11-03
    Description: Poor individuals often engage in behaviors, such as excessive borrowing, that reinforce the conditions of poverty. Some explanations for these behaviors focus on personality traits of the poor. Others emphasize environmental factors such as housing or financial access. We instead consider how certain behaviors stem simply from having less. We suggest that scarcity changes how people allocate attention: It leads them to engage more deeply in some problems while neglecting others. Across several experiments, we show that scarcity leads to attentional shifts that can help to explain behaviors such as overborrowing. We discuss how this mechanism might also explain other puzzles of poverty.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Shah, Anuj K -- Mullainathan, Sendhil -- Shafir, Eldar -- New York, N.Y. -- Science. 2012 Nov 2;338(6107):682-5. doi: 10.1126/science.1222426.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Booth School of Business, University of Chicago, Chicago, IL 60637, USA. anuj.shah@chicagobooth.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/23118192" target="_blank"〉PubMed〈/a〉

    Probing meiotic recombination and aneuploidy of single sperm cells by whole-genome sequencing (2012)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2012-12-22
    Description: Meiotic recombination creates genetic diversity and ensures segregation of homologous chromosomes. Previous population analyses yielded results averaged among individuals and affected by evolutionary pressures. We sequenced 99 sperm from an Asian male by using the newly developed amplification method-multiple annealing and looping-based amplification cycles-to phase the personal genome and map recombination events at high resolution, which are nonuniformly distributed across the genome in the absence of selection pressure. The paucity of recombination near transcription start sites observed in individual sperm indicates that such a phenomenon is intrinsic to the molecular mechanism of meiosis. Interestingly, a decreased crossover frequency combined with an increase of autosomal aneuploidy is observable on a global per-sperm basis.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3590491/" 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/PMC3590491/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lu, Sijia -- Zong, Chenghang -- Fan, Wei -- Yang, Mingyu -- Li, Jinsen -- Chapman, Alec R -- Zhu, Ping -- Hu, Xuesong -- Xu, Liya -- Yan, Liying -- Bai, Fan -- Qiao, Jie -- Tang, Fuchou -- Li, Ruiqiang -- Xie, X Sunney -- HG005097-1/HG/NHGRI NIH HHS/ -- HG005613-01/HG/NHGRI NIH HHS/ -- R01 HG005097/HG/NHGRI NIH HHS/ -- RC2 HG005613/HG/NHGRI NIH HHS/ -- New York, N.Y. -- Science. 2012 Dec 21;338(6114):1627-30. doi: 10.1126/science.1229112.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Chemistry and Chemical Biology, Harvard University, Cambridge, MA 02138, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/23258895" target="_blank"〉PubMed〈/a〉

    Multiplex targeted sequencing identifies recurrently mutated genes in autism spectrum disorders (2012)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2012-11-20
    Description: Exome sequencing studies of autism spectrum disorders (ASDs) have identified many de novo mutations but few recurrently disrupted genes. We therefore developed a modified molecular inversion probe method enabling ultra-low-cost candidate gene resequencing in very large cohorts. To demonstrate the power of this approach, we captured and sequenced 44 candidate genes in 2446 ASD probands. We discovered 27 de novo events in 16 genes, 59% of which are predicted to truncate proteins or disrupt splicing. We estimate that recurrent disruptive mutations in six genes-CHD8, DYRK1A, GRIN2B, TBR1, PTEN, and TBL1XR1-may contribute to 1% of sporadic ASDs. Our data support associations between specific genes and reciprocal subphenotypes (CHD8-macrocephaly and DYRK1A-microcephaly) and replicate the importance of a beta-catenin-chromatin-remodeling network to ASD etiology.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3528801/" 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/PMC3528801/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉O'Roak, Brian J -- Vives, Laura -- Fu, Wenqing -- Egertson, Jarrett D -- Stanaway, Ian B -- Phelps, Ian G -- Carvill, Gemma -- Kumar, Akash -- Lee, Choli -- Ankenman, Katy -- Munson, Jeff -- Hiatt, Joseph B -- Turner, Emily H -- Levy, Roie -- O'Day, Diana R -- Krumm, Niklas -- Coe, Bradley P -- Martin, Beth K -- Borenstein, Elhanan -- Nickerson, Deborah A -- Mefford, Heather C -- Doherty, Dan -- Akey, Joshua M -- Bernier, Raphael -- Eichler, Evan E -- Shendure, Jay -- HD065285/HD/NICHD NIH HHS/ -- HL-102923/HL/NHLBI NIH HHS/ -- HL-102924/HL/NHLBI NIH HHS/ -- HL-102925/HL/NHLBI NIH HHS/ -- HL-102926/HL/NHLBI NIH HHS/ -- HL-103010/HL/NHLBI NIH HHS/ -- NS069605/NS/NINDS NIH HHS/ -- R01 HD065285/HD/NICHD NIH HHS/ -- R01 NS064077/NS/NINDS NIH HHS/ -- R01 NS069605/NS/NINDS NIH HHS/ -- RC2 HL102926/HL/NHLBI NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2012 Dec 21;338(6114):1619-22. doi: 10.1126/science.1227764.

    A steroid receptor-microRNA switch regulates life span in response to signals from the gonad (2012)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2012-12-15
    Description: Although the gonad primarily functions in procreation, it also affects animal life span. Here, we show that removal of the Caenorhabditis elegans germ line triggers a switch in the regulatory state of the organism to promote longevity, co-opting components involved in larval developmental timing circuits. These components include the DAF-12 steroid receptor, which is involved in the larval stage two-to-stage three (L2-L3) transition and up-regulates members of the let-7 microRNA (miRNA) family. The miRNAs target an early larval nuclear factor lin-14 and akt-1/kinase, thereby stimulating DAF-16/FOXO signaling to extend life. Our studies suggest that metazoan life span is coupled to the gonad through elements of a developmental timer.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3909774/" 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/PMC3909774/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Shen, Yidong -- Wollam, Joshua -- Magner, Daniel -- Karalay, Oezlem -- Antebi, Adam -- R01 AG027498/AG/NIA NIH HHS/ -- T32 GM008231/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2012 Dec 14;338(6113):1472-6. doi: 10.1126/science.1228967.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Max Planck Institute for Biology of Ageing, Joseph-Stelzmann-Strasse 9b, D-50931 Cologne, Germany.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/23239738" target="_blank"〉PubMed〈/a〉

    Oxytocin/vasopressin-related peptides have an ancient role in reproductive behavior (2012)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2012-11-01
    Description: Many biological functions are conserved, but the extent to which conservation applies to integrative behaviors is unknown. Vasopressin and oxytocin neuropeptides are strongly implicated in mammalian reproductive and social behaviors, yet rodent loss-of-function mutants have relatively subtle behavioral defects. Here we identify an oxytocin/vasopressin-like signaling system in Caenorhabditis elegans, consisting of a peptide and two receptors that are expressed in sexually dimorphic patterns. Males lacking the peptide or its receptors perform poorly in reproductive behaviors, including mate search, mate recognition, and mating, but other sensorimotor behaviors are intact. Quantitative analysis indicates that mating motor patterns are fragmented and inefficient in mutants, suggesting that oxytocin/vasopressin peptides increase the coherence of mating behaviors. These results indicate that conserved molecules coordinate diverse behavioral motifs in reproductive behavior.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3597094/" 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/PMC3597094/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Garrison, Jennifer L -- Macosko, Evan Z -- Bernstein, Samantha -- Pokala, Navin -- Albrecht, Dirk R -- Bargmann, Cornelia I -- GM07739/GM/NIGMS NIH HHS/ -- K99 GM092859/GM/NIGMS NIH HHS/ -- K99GM092859/GM/NIGMS NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2012 Oct 26;338(6106):540-3. doi: 10.1126/science.1226201.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Howard Hughes Medical Institute, Lulu and Anthony Wang Laboratory of Neural Circuits and Behavior, The Rockefeller University, New York, NY 10065, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/23112335" target="_blank"〉PubMed〈/a〉

    dSarm/Sarm1 is required for activation of an injury-induced axon death pathway (2012)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2012-06-09
    Description: Axonal and synaptic degeneration is a hallmark of peripheral neuropathy, brain injury, and neurodegenerative disease. Axonal degeneration has been proposed to be mediated by an active autodestruction program, akin to apoptotic cell death; however, loss-of-function mutations capable of potently blocking axon self-destruction have not been described. Here, we show that loss of the Drosophila Toll receptor adaptor dSarm (sterile alpha/Armadillo/Toll-Interleukin receptor homology domain protein) cell-autonomously suppresses Wallerian degeneration for weeks after axotomy. Severed mouse Sarm1 null axons exhibit remarkable long-term survival both in vivo and in vitro, indicating that Sarm1 prodegenerative signaling is conserved in mammals. Our results provide direct evidence that axons actively promote their own destruction after injury and identify dSarm/Sarm1 as a member of an ancient axon death signaling pathway.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Osterloh, Jeannette M -- Yang, Jing -- Rooney, Timothy M -- Fox, A Nicole -- Adalbert, Robert -- Powell, Eric H -- Sheehan, Amy E -- Avery, Michelle A -- Hackett, Rachel -- Logan, Mary A -- MacDonald, Jennifer M -- Ziegenfuss, Jennifer S -- Milde, Stefan -- Hou, Ying-Ju -- Nathan, Carl -- Ding, Aihao -- Brown, Robert H Jr -- Conforti, Laura -- Coleman, Michael -- Tessier-Lavigne, Marc -- Zuchner, Stephan -- Freeman, Marc R -- 5R01-NS050557-05/NS/NINDS NIH HHS/ -- AI030165/AI/NIAID NIH HHS/ -- R01NS059991/NS/NINDS NIH HHS/ -- R01NS072248/NS/NINDS NIH HHS/ -- RC2-NS070-342/NS/NINDS NIH HHS/ -- U54NS065712/NS/NINDS NIH HHS/ -- Biotechnology and Biological Sciences Research Council/United Kingdom -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2012 Jul 27;337(6093):481-4. doi: 10.1126/science.1223899.

    Vasopressin/oxytocin-related signaling regulates gustatory associative learning in C. elegans (2012)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2012-11-01
    Description: Vasopressin- and oxytocin-related neuropeptides are key regulators of animal physiology, including water balance and reproduction. Although these neuropeptides also modulate social behavior and cognition in mammals, the mechanism for influencing behavioral plasticity and the evolutionary origin of these effects are not well understood. Here, we present a functional vasopressin- and oxytocin-like signaling system in the nematode Caenorhabditis elegans. Through activation of its receptor NTR-1, a vasopressin/oxytocin-related neuropeptide, designated nematocin, facilitates the experience-driven modulation of salt chemotaxis, a type of gustatory associative learning in C. elegans. Our study suggests that vasopressin and oxytocin neuropeptides have ancient roles in modulating sensory processing in neural circuits that underlie behavioral plasticity.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Beets, Isabel -- Janssen, Tom -- Meelkop, Ellen -- Temmerman, Liesbet -- Suetens, Nick -- Rademakers, Suzanne -- Jansen, Gert -- Schoofs, Liliane -- New York, N.Y. -- Science. 2012 Oct 26;338(6106):543-5. doi: 10.1126/science.1226860.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biology, Functional Genomics and Proteomics Unit, KU Leuven, 3000 Leuven, Belgium.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/23112336" target="_blank"〉PubMed〈/a〉

    Illusions promote mating success in great bowerbirds (2012)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2012-01-24
    Description: Sexual selection studies normally compare signal strengths, but signal components and sensory processing may interact to create misleading or attention-capturing illusions. Visual illusions can be produced by altering object and scene geometry in ways that trick the viewer when seen from a particular direction. Male great bowerbirds actively maintain size-distance gradients of objects on their bower courts that create forced-perspective illusions for females viewing their displays from within the bower avenue. We show a significant relationship between mating success and the female's view of the gradient; this view explains substantially more variance in mating success than the strength of the gradients. Illusions may be widespread in other animals because males of most species display to females with characteristic orientation and distance, providing excellent conditions for illusions.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kelley, Laura A -- Endler, John A -- New York, N.Y. -- Science. 2012 Jan 20;335(6066):335-8. doi: 10.1126/science.1212443.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Centre for Integrative Ecology, School of Life & Environmental Sciences, Deakin University, Geelong, VIC 3216, Australia.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/22267812" target="_blank"〉PubMed〈/a〉

    Sexual deprivation increases ethanol intake in Drosophila (2012)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2012-03-17
    Description: The brain's reward systems reinforce behaviors required for species survival, including sex, food consumption, and social interaction. Drugs of abuse co-opt these neural pathways, which can lead to addiction. Here, we used Drosophila melanogaster to investigate the relationship between natural and drug rewards. In males, mating increased, whereas sexual deprivation reduced, neuropeptide F (NPF) levels. Activation or inhibition of the NPF system in turn reduced or enhanced ethanol preference. These results thus link sexual experience, NPF system activity, and ethanol consumption. Artificial activation of NPF neurons was in itself rewarding and precluded the ability of ethanol to act as a reward. We propose that activity of the NPF-NPF receptor axis represents the state of the fly reward system and modifies behavior accordingly.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3909676/" 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/PMC3909676/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Shohat-Ophir, G -- Kaun, K R -- Azanchi, R -- Mohammed, H -- Heberlein, U -- R01 AA010035/AA/NIAAA NIH HHS/ -- New York, N.Y. -- Science. 2012 Mar 16;335(6074):1351-5. doi: 10.1126/science.1215932.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Anatomy, University of California, San Francisco, CA 94143-2822, USA. shohatophirg@janelia.hhmi.org〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/22422983" target="_blank"〉PubMed〈/a〉

    Analytic thinking promotes religious disbelief (2012)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2012-04-28
    Description: Scientific interest in the cognitive underpinnings of religious belief has grown in recent years. However, to date, little experimental research has focused on the cognitive processes that may promote religious disbelief. The present studies apply a dual-process model of cognitive processing to this problem, testing the hypothesis that analytic processing promotes religious disbelief. Individual differences in the tendency to analytically override initially flawed intuitions in reasoning were associated with increased religious disbelief. Four additional experiments provided evidence of causation, as subtle manipulations known to trigger analytic processing also encouraged religious disbelief. Combined, these studies indicate that analytic processing is one factor (presumably among several) that promotes religious disbelief. Although these findings do not speak directly to conversations about the inherent rationality, value, or truth of religious beliefs, they illuminate one cognitive factor that may influence such discussions.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gervais, Will M -- Norenzayan, Ara -- New York, N.Y. -- Science. 2012 Apr 27;336(6080):493-6. doi: 10.1126/science.1215647.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉University of British Columbia, Vancouver, BC, Canada. will@psych.ubc.ca〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/22539725" target="_blank"〉PubMed〈/a〉

    Kinship categories across languages reflect general communicative principles (2012)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2012-05-26
    Description: Languages vary in their systems of kinship categories, but the scope of possible variation appears to be constrained. Previous accounts of kin classification have often emphasized constraints that are specific to the domain of kinship and are not derived from general principles. Here, we propose an account that is founded on two domain-general principles: Good systems of categories are simple, and they enable informative communication. We show computationally that kin classification systems in the world's languages achieve a near-optimal trade-off between these two competing principles. We also show that our account explains several specific constraints on kin classification proposed previously. Because the principles of simplicity and informativeness are also relevant to other semantic domains, the trade-off between them may provide a domain-general foundation for variation in category systems across languages.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kemp, Charles -- Regier, Terry -- New York, N.Y. -- Science. 2012 May 25;336(6084):1049-54. doi: 10.1126/science.1218811.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Psychology, Carnegie Mellon University, Pittsburgh, PA 15213, USA. ckemp@cmu.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/22628658" target="_blank"〉PubMed〈/a〉

    Closed-loop control of epilepsy by transcranial electrical stimulation (2012)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2012-08-11
    Description: Many neurological and psychiatric diseases are associated with clinically detectable, altered brain dynamics. The aberrant brain activity, in principle, can be restored through electrical stimulation. In epilepsies, abnormal patterns emerge intermittently, and therefore, a closed-loop feedback brain control that leaves other aspects of brain functions unaffected is desirable. Here, we demonstrate that seizure-triggered, feedback transcranial electrical stimulation (TES) can dramatically reduce spike-and-wave episodes in a rodent model of generalized epilepsy. Closed-loop TES can be an effective clinical tool to reduce pathological brain patterns in drug-resistant patients.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Berenyi, Antal -- Belluscio, Mariano -- Mao, Dun -- Buzsaki, Gyorgy -- MH54671/MH/NIMH NIH HHS/ -- NS074015/NS/NINDS NIH HHS/ -- NS34994/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 2012 Aug 10;337(6095):735-7. doi: 10.1126/science.1223154.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Center for Molecular and Behavioral Neuroscience, Rutgers University, Newark, NJ 07102, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/22879515" target="_blank"〉PubMed〈/a〉

    Drosophila dosage compensation involves enhanced Pol II recruitment to male X-linked promoters (2012)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2012-07-24
    Description: Through hyperacetylation of histone H4 lysine 16 (H4K16), the male-specific lethal (MSL) complex in Drosophila approximately doubles transcription from the single male X chromosome in order to match X-linked expression in females and expression from diploid autosomes. By obtaining accurate measurements of RNA polymerase II (Pol II) occupancies and short promoter-proximal RNA production, we detected a consistent, genome-scale increase in Pol II activity at the promoters of male X-linked genes. Moreover, we found that enhanced Pol II recruitment to male X-linked promoters is largely dependent on the MSL complex. These observations provide insights into how global modulation of chromatin structure by histone acetylation contributes to the precise control of Pol II function.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Conrad, Thomas -- Cavalli, Florence M G -- Vaquerizas, Juan M -- Luscombe, Nicholas M -- Akhtar, Asifa -- Cancer Research UK/United Kingdom -- New York, N.Y. -- Science. 2012 Aug 10;337(6095):742-6. doi: 10.1126/science.1221428.

    Copy number variation of multiple genes at Rhg1 mediates nematode resistance in soybean (2012)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2012-10-16
    Description: The rhg1-b allele of soybean is widely used for resistance against soybean cyst nematode (SCN), the most economically damaging pathogen of soybeans in the United States. Gene silencing showed that genes in a 31-kilobase segment at rhg1-b, encoding an amino acid transporter, an alpha-SNAP protein, and a WI12 (wound-inducible domain) protein, each contribute to resistance. There is one copy of the 31-kilobase segment per haploid genome in susceptible varieties, but 10 tandem copies are present in an rhg1-b haplotype. Overexpression of the individual genes in roots was ineffective, but overexpression of the genes together conferred enhanced SCN resistance. Hence, SCN resistance mediated by the soybean quantitative trait locus Rhg1 is conferred by copy number variation that increases the expression of a set of dissimilar genes in a repeated multigene segment.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Cook, David E -- Lee, Tong Geon -- Guo, Xiaoli -- Melito, Sara -- Wang, Kai -- Bayless, Adam M -- Wang, Jianping -- Hughes, Teresa J -- Willis, David K -- Clemente, Thomas E -- Diers, Brian W -- Jiang, Jiming -- Hudson, Matthew E -- Bent, Andrew F -- New York, N.Y. -- Science. 2012 Nov 30;338(6111):1206-9. doi: 10.1126/science.1228746.

    Germ cell migration across Sertoli cell tight junctions (2012)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2012-09-22
    Description: The blood-testis barrier includes strands of tight junctions between somatic Sertoli cells that restricts solutes from crossing the paracellular space, creating a microenvironment within seminiferous tubules and providing immune privilege to meiotic and postmeiotic cells. Large cysts of germ cells transit the Sertoli cell tight junctions (SCTJs) without compromising their integrity. We used confocal microscopy to visualize SCTJ components during germ cell cyst migration across the SCTJs. Cysts become enclosed within a network of transient compartments fully bounded by old and new tight junctions. Dissolution of the old tight junctions releases the germ cells into the adluminal compartment, thus completing transit across the blood-testis barrier. Claudin 3, a tight junction protein, is transiently incorporated into new tight junctions and then replaced by claudin 11.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3694388/" 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/PMC3694388/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Smith, Benjamin E -- Braun, Robert E -- CA34196/CA/NCI NIH HHS/ -- HD12629/HD/NICHD NIH HHS/ -- P30 CA034196/CA/NCI NIH HHS/ -- U54 HD012629/HD/NICHD NIH HHS/ -- New York, N.Y. -- Science. 2012 Nov 9;338(6108):798-802. doi: 10.1126/science.1219969.

    EZH2 oncogenic activity in castration-resistant prostate cancer cells is Polycomb-independent (2012)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2012-12-15
    Description: Epigenetic regulators represent a promising new class of therapeutic targets for cancer. Enhancer of zeste homolog 2 (EZH2), a subunit of Polycomb repressive complex 2 (PRC2), silences gene expression via its histone methyltransferase activity. We found that the oncogenic function of EZH2 in cells of castration-resistant prostate cancer is independent of its role as a transcriptional repressor. Instead, it involves the ability of EZH2 to act as a coactivator for critical transcription factors including the androgen receptor. This functional switch is dependent on phosphorylation of EZH2 and requires an intact methyltransferase domain. Hence, targeting the non-PRC2 function of EZH2 may have therapeutic efficacy for treating metastatic, hormone-refractory prostate cancer.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3625962/" 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/PMC3625962/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Xu, Kexin -- Wu, Zhenhua Jeremy -- Groner, Anna C -- He, Housheng Hansen -- Cai, Changmeng -- Lis, Rosina T -- Wu, Xiaoqiu -- Stack, Edward C -- Loda, Massimo -- Liu, Tao -- Xu, Han -- Cato, Laura -- Thornton, James E -- Gregory, Richard I -- Morrissey, Colm -- Vessella, Robert L -- Montironi, Rodolfo -- Magi-Galluzzi, Cristina -- Kantoff, Philip W -- Balk, Steven P -- Liu, X Shirley -- Brown, Myles -- CA090381/CA/NCI NIH HHS/ -- CA097186/CA/NCI NIH HHS/ -- CA111803/CA/NCI NIH HHS/ -- CA131945/CA/NCI NIH HHS/ -- CA166507/CA/NCI NIH HHS/ -- CA85859/CA/NCI NIH HHS/ -- CA89021/CA/NCI NIH HHS/ -- CA90381/CA/NCI NIH HHS/ -- GM99409/GM/NIGMS NIH HHS/ -- K99 CA166507/CA/NCI NIH HHS/ -- P50 CA090381/CA/NCI NIH HHS/ -- R01 GM099409/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2012 Dec 14;338(6113):1465-9. doi: 10.1126/science.1227604.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Center for Functional Cancer Epigenetics, Dana-Farber Cancer Institute, Boston, MA 02215, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/23239736" target="_blank"〉PubMed〈/a〉

    A memory retrieval-extinction procedure to prevent drug craving and relapse (2012)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2012-04-14
    Description: Drug use and relapse involve learned associations between drug-associated environmental cues and drug effects. Extinction procedures in the clinic can suppress conditioned responses to drug cues, but the extinguished responses typically reemerge after exposure to the drug itself (reinstatement), the drug-associated environment (renewal), or the passage of time (spontaneous recovery). We describe a memory retrieval-extinction procedure that decreases conditioned drug effects and drug seeking in rat models of relapse, and drug craving in abstinent heroin addicts. In rats, daily retrieval of drug-associated memories 10 minutes or 1 hour but not 6 hours before extinction sessions attenuated drug-induced reinstatement, spontaneous recovery, and renewal of conditioned drug effects and drug seeking. In heroin addicts, retrieval of drug-associated memories 10 minutes before extinction sessions attenuated cue-induced heroin craving 1, 30, and 180 days later. The memory retrieval-extinction procedure is a promising nonpharmacological method for decreasing drug craving and relapse during abstinence.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3695463/" 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/PMC3695463/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Xue, Yan-Xue -- Luo, Yi-Xiao -- Wu, Ping -- Shi, Hai-Shui -- Xue, Li-Fen -- Chen, Chen -- Zhu, Wei-Li -- Ding, Zeng-Bo -- Bao, Yan-ping -- Shi, Jie -- Epstein, David H -- Shaham, Yavin -- Lu, Lin -- Z99 DA999999/Intramural NIH HHS/ -- ZIA DA000434-12/Intramural NIH HHS/ -- New York, N.Y. -- Science. 2012 Apr 13;336(6078):241-5. doi: 10.1126/science.1215070.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉National Institute on Drug Dependence, Peking University, Beijing, China.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/22499948" target="_blank"〉PubMed〈/a〉

    A mutation in EGF repeat-8 of Notch discriminates between Serrate/Jagged and Delta family ligands (2012)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2012-12-01
    Description: Notch signaling affects many developmental and cellular processes and has been implicated in congenital disorders, stroke, and numerous cancers. The Notch receptor binds its ligands Delta and Serrate and is able to discriminate between them in different contexts. However, the specific domains in Notch responsible for this selectivity are poorly defined. Through genetic screens in Drosophila, we isolated a mutation, Notch(jigsaw), that affects Serrate- but not Delta-dependent signaling. Notch(jigsaw) carries a missense mutation in epidermal growth factor repeat-8 (EGFr-8) and is defective in Serrate binding. A homologous point mutation in mammalian Notch2 also exhibits defects in signaling of a mammalian Serrate homolog, Jagged1. Hence, an evolutionarily conserved valine in EGFr-8 is essential for ligand selectivity and provides a molecular handle to study numerous Notch-dependent signaling events.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3663443/" 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/PMC3663443/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Yamamoto, Shinya -- Charng, Wu-Lin -- Rana, Nadia A -- Kakuda, Shinako -- Jaiswal, Manish -- Bayat, Vafa -- Xiong, Bo -- Zhang, Ke -- Sandoval, Hector -- David, Gabriela -- Wang, Hao -- Haltiwanger, Robert S -- Bellen, Hugo J -- 1RC4GM096355-01/GM/NIGMS NIH HHS/ -- 5K12GM084897/GM/NIGMS NIH HHS/ -- 5P30HD024064/HD/NICHD NIH HHS/ -- 5R01GM061126-12/GM/NIGMS NIH HHS/ -- 5R01GM067858/GM/NIGMS NIH HHS/ -- 5T32-HD055200/HD/NICHD NIH HHS/ -- K12 GM084897/GM/NIGMS NIH HHS/ -- P30 HD024064/HD/NICHD NIH HHS/ -- R01 GM061126/GM/NIGMS NIH HHS/ -- R01 GM067858/GM/NIGMS NIH HHS/ -- RC4 GM096355/GM/NIGMS NIH HHS/ -- T32 HD055200/HD/NICHD NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2012 Nov 30;338(6111):1229-32. doi: 10.1126/science.1228745.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Program in Developmental Biology, Baylor College of Medicine, Houston, TX 77030, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/23197537" target="_blank"〉PubMed〈/a〉

    Bacterial quorum sensing and metabolic incentives to cooperate (2012)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2012-10-16
    Description: The opportunistic pathogen Pseudomonas aeruginosa uses a cell-cell communication system termed "quorum sensing" to control production of public goods, extracellular products that can be used by any community member. Not all individuals respond to quorum-sensing signals and synthesize public goods. Such social cheaters enjoy the benefits of the products secreted by cooperators. There are some P. aeruginosa cellular enzymes controlled by quorum sensing, and we show that quorum sensing-controlled expression of such private goods can put a metabolic constraint on social cheating and prevent a tragedy of the commons. Metabolic constraint of social cheating provides an explanation for private-goods regulation by a cooperative system and has general implications for population biology, infection control, and stabilization of quorum-sensing circuits in synthetic biology.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3587168/" 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/PMC3587168/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Dandekar, Ajai A -- Chugani, Sudha -- Greenberg, E Peter -- GM-59026/GM/NIGMS NIH HHS/ -- P30 DK 89507/DK/NIDDK NIH HHS/ -- P30 DK089507/DK/NIDDK NIH HHS/ -- R01 GM059026/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2012 Oct 12;338(6104):264-6. doi: 10.1126/science.1227289.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Division of Pulmonary and Critical Care Medicine, University of Washington School of Medicine, Seattle, WA 98195, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/23066081" target="_blank"〉PubMed〈/a〉
