    Description: Genetic exchange has not been shown to be a mechanism underlying the extensive diversity of Leishmania parasites. We report here evidence that the invertebrate stages of Leishmania are capable of having a sexual cycle consistent with a meiotic process like that described for African trypanosomes. Hybrid progeny were generated that bore full genomic complements from both parents, but kinetoplast DNA maxicircles from one parent. Mating occurred only in the sand fly vector, and hybrids were transmitted to the mammalian host by sand fly bite. Genetic exchange likely contributes to phenotypic diversity in natural populations, and analysis of hybrid progeny will be useful for positional cloning of the genes controlling traits such as virulence, tissue tropism, and drug resistance.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2729066/" 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/PMC2729066/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Akopyants, Natalia S -- Kimblin, Nicola -- Secundino, Nagila -- Patrick, Rachel -- Peters, Nathan -- Lawyer, Phillip -- Dobson, Deborah E -- Beverley, Stephen M -- Sacks, David L -- A1020941/PHS HHS/ -- A1029646/PHS HHS/ -- R01 AI029646/AI/NIAID NIH HHS/ -- R01 AI029646-20/AI/NIAID NIH HHS/ -- Intramural NIH HHS/ -- New York, N.Y. -- Science. 2009 Apr 10;324(5924):265-8. doi: 10.1126/science.1169464.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Molecular Microbiology, Washington University School of Medicine, St. Louis, MO 63110, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19359589" target="_blank"〉PubMed〈/a〉

    Description: Sleep deprivation can impair human health and performance. Habitual total sleep time and homeostatic sleep response to sleep deprivation are quantitative traits in humans. Genetic loci for these traits have been identified in model organisms, but none of these potential animal models have a corresponding human genotype and phenotype. We have identified a mutation in a transcriptional repressor (hDEC2-P385R) that is associated with a human short sleep phenotype. Activity profiles and sleep recordings of transgenic mice carrying this mutation showed increased vigilance time and less sleep time than control mice in a zeitgeber time- and sleep deprivation-dependent manner. These mice represent a model of human sleep homeostasis that provides an opportunity to probe the effect of sleep on human physical and mental health.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2884988/" 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/PMC2884988/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉He, Ying -- Jones, Christopher R -- Fujiki, Nobuhiro -- Xu, Ying -- Guo, Bin -- Holder, Jimmy L Jr -- Rossner, Moritz J -- Nishino, Seiji -- Fu, Ying-Hui -- HL059596/HL/NHLBI NIH HHS/ -- MH074924/MH/NIMH NIH HHS/ -- R01 HL059596/HL/NHLBI NIH HHS/ -- R01 HL059596-09/HL/NHLBI NIH HHS/ -- New York, N.Y. -- Science. 2009 Aug 14;325(5942):866-70. doi: 10.1126/science.1174443.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Neurology, University of California at San Francisco, Mission Bay, 1550 Fourth Street, San Francisco, CA 94158, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19679812" target="_blank"〉PubMed〈/a〉

    Description: Understanding of plant-pathogen coevolution in natural systems continues to develop as new theories at the population and species level are increasingly informed by studies unraveling the molecular basis of interactions between individual plants and their pathogens. The next challenge lies in further integration of these approaches to develop a comprehensive picture of how life history traits of both players interact with the environment to shape evolutionary trajectories.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2689373/" 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/PMC2689373/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Burdon, Jeremy J -- Thrall, Peter H -- R01 GM074265-01A2/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2009 May 8;324(5928):755-6. doi: 10.1126/science.1171663.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Commonwealth Scientific and Industrial Research Organization (CSIRO)-Plant Industry, Post Office Box 1600, Canberra, ACT 2601, Australia.

    Description: Fanconi anemia is a human cancer predisposition syndrome caused by mutations in 13 Fanc genes. The disorder is characterized by genomic instability and cellular hypersensitivity to chemicals that generate DNA interstrand cross-links (ICLs). A central event in the activation of the Fanconi anemia pathway is the mono-ubiquitylation of the FANCI-FANCD2 complex, but how this complex confers ICL resistance remains enigmatic. Using a cell-free system, we showed that FANCI-FANCD2 is required for replication-coupled ICL repair in S phase. Removal of FANCD2 from extracts inhibits both nucleolytic incisions near the ICL and translesion DNA synthesis past the lesion. Reversal of these defects requires ubiquitylated FANCI-FANCD2. Our results show that multiple steps of the essential S-phase ICL repair mechanism fail when the Fanconi anemia pathway is compromised.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2909596/" 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/PMC2909596/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Knipscheer, Puck -- Raschle, Markus -- Smogorzewska, Agata -- Enoiu, Milica -- Ho, The Vinh -- Scharer, Orlando D -- Elledge, Stephen J -- Walter, Johannes C -- GM62267/GM/NIGMS NIH HHS/ -- R01 GM062267/GM/NIGMS NIH HHS/ -- R01 GM062267-09/GM/NIGMS NIH HHS/ -- R37 GM044664/GM/NIGMS NIH HHS/ -- R37 GM044664-23/GM/NIGMS NIH HHS/ -- T32CA09216/CA/NCI NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2009 Dec 18;326(5960):1698-701. doi: 10.1126/science.1182372.

    Description: Ecological speciation occurs when ecologically based, divergent selection causes the evolution of reproductive isolation. There are many empirical examples of this process; however, there exists a poorly characterized stage during which the traits that distinguish species ecologically and reproductively segregate in a single population. By using a combination of genetic mapping, mate-choice experiments, field observations, and population genetics, we studied a butterfly population with a mimetic wing color polymorphism and found that the butterflies exhibited partial, color-based, assortative mate preference. These traits represent the divergent, ecologically based signal and preference components of sexual isolation that usually distinguish incipient and sibling species. The association between behavior and recognition trait in a single population may enhance the probability of speciation and provides an example of the missing link between an interbreeding population and isolated species.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2875868/" 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/PMC2875868/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Chamberlain, Nicola L -- Hill, Ryan I -- Kapan, Durrell D -- Gilbert, Lawrence E -- Kronforst, Marcus R -- GM068763/GM/NIGMS NIH HHS/ -- P50 GM068763/GM/NIGMS NIH HHS/ -- P50 GM068763-06/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2009 Nov 6;326(5954):847-50. doi: 10.1126/science.1179141.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Faculty of Arts and Sciences Center for Systems Biology, Harvard University, Cambridge, MA 02138, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19892982" target="_blank"〉PubMed〈/a〉

    Description: Children acquire their native language according to a well-defined time frame. Surprisingly, although children raised in bilingual environments have to learn roughly twice as much about language as their monolingual peers, the speed of acquisition is comparable in monolinguals and bilinguals. Here, we show that preverbal 12-month-old bilingual infants have become more flexible at learning speech structures than monolinguals. When given the opportunity to simultaneously learn two different regularities, bilingual infants learned both, whereas monolinguals learned only one of them. Hence, bilinguals may acquire two languages in the time in which monolinguals acquire one because they quickly become more flexible learners.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kovacs, Agnes Melinda -- Mehler, Jacques -- New York, N.Y. -- Science. 2009 Jul 31;325(5940):611-2. doi: 10.1126/science.1173947.

    Description: Throughout the history of mathematics, concepts of number and space have been tightly intertwined. We tested the hypothesis that cortical circuits for spatial attention contribute to mental arithmetic in humans. We trained a multivariate classifier algorithm to infer the direction of an eye movement, left or right, from the brain activation measured in the posterior parietal cortex. Without further training, the classifier then generalized to an arithmetic task. Its left versus right classification could be used to sort out subtraction versus addition trials, whether performed with symbols or with sets of dots. These findings are consistent with the suggestion that mental arithmetic co-opts parietal circuitry associated with spatial coding.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Knops, Andre -- Thirion, Bertrand -- Hubbard, Edward M -- Michel, Vincent -- Dehaene, Stanislas -- New York, N.Y. -- Science. 2009 Jun 19;324(5934):1583-5. doi: 10.1126/science.1171599.

    Description: Platelets play a critical role in the pathogenesis of malarial infections by encouraging the sequestration of infected red blood cells within the cerebral vasculature. But platelets also have well-established roles in innate protection against microbial infections. We found that purified human platelets killed Plasmodium falciparum parasites cultured in red blood cells. Inhibition of platelet function by aspirin and other platelet inhibitors abrogated the lethal effect human platelets exert on P. falciparum parasites. Likewise, platelet-deficient and aspirin-treated mice were more susceptible to death during erythrocytic infection with Plasmodium chabaudi. Both mouse and human platelets bind malarial-infected red cells and kill the parasite within. These results indicate a protective function for platelets in the early stages of erythrocytic infection distinct from their role in cerebral malaria.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉McMorran, Brendan J -- Marshall, Vikki M -- de Graaf, Carolyn -- Drysdale, Karen E -- Shabbar, Meriam -- Smyth, Gordon K -- Corbin, Jason E -- Alexander, Warren S -- Foote, Simon J -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2009 Feb 6;323(5915):797-800. doi: 10.1126/science.1166296.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Menzies Research Institute, University of Tasmania, Private Bag 23, Hobart, Tasmania 7000, Australia. brendan.mcmorran@utas.edu.au〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19197068" target="_blank"〉PubMed〈/a〉

    Description: Climate change could lead to mismatches between the reproductive cycles of marine organisms and their planktonic food. We tested this hypothesis by comparing shrimp (Pandalus borealis) egg hatching times and satellite-derived phytoplankton bloom dynamics throughout the North Atlantic. At large spatial and long temporal (10 years or longer) scales, hatching was correlated with the timing of the spring phytoplankton bloom. Annual egg development and hatching times were determined locally by bottom water temperature. We conclude that different populations of P. borealis have adapted to local temperatures and bloom timing, matching egg hatching to food availability under average conditions. This strategy is vulnerable to interannual oceanographic variability and long-term climatic changes.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Koeller, P -- Fuentes-Yaco, C -- Platt, T -- Sathyendranath, S -- Richards, A -- Ouellet, P -- Orr, D -- Skuladottir, U -- Wieland, K -- Savard, L -- Aschan, M -- New York, N.Y. -- Science. 2009 May 8;324(5928):791-3. doi: 10.1126/science.1170987.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Fisheries and Oceans, Bedford Institute of Oceanography, Post Office Box 1006, Dartmouth, B2Y 4A2 Nova Scotia, Canada. koellerp@mar.dfo-mpo.gc.ca〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19423827" target="_blank"〉PubMed〈/a〉

    Description: X-linked adrenoleukodystrophy (ALD) is a severe brain demyelinating disease in boys that is caused by a deficiency in ALD protein, an adenosine triphosphate-binding cassette transporter encoded by the ABCD1 gene. ALD progression can be halted by allogeneic hematopoietic cell transplantation (HCT). We initiated a gene therapy trial in two ALD patients for whom there were no matched donors. Autologous CD34+ cells were removed from the patients, genetically corrected ex vivo with a lentiviral vector encoding wild-type ABCD1, and then re-infused into the patients after they had received myeloablative treatment. Over a span of 24 to 30 months of follow-up, we detected polyclonal reconstitution, with 9 to 14% of granulocytes, monocytes, and T and B lymphocytes expressing the ALD protein. These results strongly suggest that hematopoietic stem cells were transduced in the patients. Beginning 14 to 16 months after infusion of the genetically corrected cells, progressive cerebral demyelination in the two patients stopped, a clinical outcome comparable to that achieved by allogeneic HCT. Thus, lentiviral-mediated gene therapy of hematopoietic stem cells can provide clinical benefits in ALD.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Cartier, Nathalie -- Hacein-Bey-Abina, Salima -- Bartholomae, Cynthia C -- Veres, Gabor -- Schmidt, Manfred -- Kutschera, Ina -- Vidaud, Michel -- Abel, Ulrich -- Dal-Cortivo, Liliane -- Caccavelli, Laure -- Mahlaoui, Nizar -- Kiermer, Veronique -- Mittelstaedt, Denice -- Bellesme, Celine -- Lahlou, Najiba -- Lefrere, Francois -- Blanche, Stephane -- Audit, Muriel -- Payen, Emmanuel -- Leboulch, Philippe -- l'Homme, Bruno -- Bougneres, Pierre -- Von Kalle, Christof -- Fischer, Alain -- Cavazzana-Calvo, Marina -- Aubourg, Patrick -- New York, N.Y. -- Science. 2009 Nov 6;326(5954):818-23. doi: 10.1126/science.1171242.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉INSERM UMR745, University Paris-Descartes, 75279 Paris, France.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19892975" target="_blank"〉PubMed〈/a〉

    Description: Cytokines such as interleukin-6 induce tyrosine and serine phosphorylation of Stat3 that results in activation of Stat3-responsive genes. We provide evidence that Stat3 is present in the mitochondria of cultured cells and primary tissues, including the liver and heart. In Stat3(-/-) cells, the activities of complexes I and II of the electron transport chain (ETC) were significantly decreased. We identified Stat3 mutants that selectively restored the protein's function as a transcription factor or its functions within the ETC. In mice that do not express Stat3 in the heart, there were also selective defects in the activities of complexes I and II of the ETC. These data indicate that Stat3 is required for optimal function of the ETC, which may allow it to orchestrate responses to cellular homeostasis.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2758306/" 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/PMC2758306/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wegrzyn, Joanna -- Potla, Ramesh -- Chwae, Yong-Joon -- Sepuri, Naresh B V -- Zhang, Qifang -- Koeck, Thomas -- Derecka, Marta -- Szczepanek, Karol -- Szelag, Magdalena -- Gornicka, Agnieszka -- Moh, Akira -- Moghaddas, Shadi -- Chen, Qun -- Bobbili, Santha -- Cichy, Joanna -- Dulak, Jozef -- Baker, Darren P -- Wolfman, Alan -- Stuehr, Dennis -- Hassan, Medhat O -- Fu, Xin-Yuan -- Avadhani, Narayan -- Drake, Jennifer I -- Fawcett, Paul -- Lesnefsky, Edward J -- Larner, Andrew C -- CA098924/CA/NCI NIH HHS/ -- P01AG15885/AG/NIA NIH HHS/ -- R01 AI059710/AI/NIAID NIH HHS/ -- R01 AI059710-03/AI/NIAID NIH HHS/ -- R01 AI059710-04/AI/NIAID NIH HHS/ -- R01 CA098924/CA/NCI NIH HHS/ -- R01 CA098924-03/CA/NCI NIH HHS/ -- R01 CA098924-04/CA/NCI NIH HHS/ -- R01 CA098924-05/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 2009 Feb 6;323(5915):793-7. doi: 10.1126/science.1164551.

    Description: Despite tremendous progress in understanding the nature of the immune system, the full diversity of an organism's antibody repertoire is unknown. We used high-throughput sequencing of the variable domain of the antibody heavy chain from 14 zebrafish to analyze VDJ usage and antibody sequence. Zebrafish were found to use between 50 and 86% of all possible VDJ combinations and shared a similar frequency distribution, with some correlation of VDJ patterns between individuals. Zebrafish antibodies retained a few thousand unique heavy chains that also exhibited a shared frequency distribution. We found evidence of convergence, in which different individuals made the same antibody. This approach provides insight into the breadth of the expressed antibody repertoire and immunological diversity at the level of an individual organism.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3086368/" 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/PMC3086368/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Weinstein, Joshua A -- Jiang, Ning -- White, Richard A 3rd -- Fisher, Daniel S -- Quake, Stephen R -- DP1 OD000251/OD/NIH HHS/ -- DP1 OD000251-04/OD/NIH HHS/ -- DP1 OD000251-05/OD/NIH HHS/ -- DP1 OD000251-06/OD/NIH HHS/ -- New York, N.Y. -- Science. 2009 May 8;324(5928):807-10. doi: 10.1126/science.1170020.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Biophysics Program, Stanford University, Stanford, CA 94305, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19423829" target="_blank"〉PubMed〈/a〉

    Description: Compared with more explicit racial slurs and statements, biased facial expressions and body language may resist conscious identification and thus produce a hidden social influence. In four studies, we show that race biases can be subtly transmitted via televised nonverbal behavior. Characters on 11 popular television shows exhibited more negative nonverbal behavior toward black than toward status-matched white characters. Critically, exposure to prowhite (versus problack) nonverbal bias increased viewers' bias even though patterns of nonverbal behavior could not be consciously reported. These findings suggest that hidden patterns of televised nonverbal behavior influence bias among viewers.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3764987/" 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/PMC3764987/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Weisbuch, Max -- Pauker, Kristin -- Ambady, Nalini -- F32 MH078350/MH/NIMH NIH HHS/ -- F32MH078350/MH/NIMH NIH HHS/ -- R01 MH070833/MH/NIMH NIH HHS/ -- R01 MH070833-02/MH/NIMH NIH HHS/ -- New York, N.Y. -- Science. 2009 Dec 18;326(5960):1711-4. doi: 10.1126/science.1178358.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Psychology, Tufts University, 490 Boston Avenue, Medford, MA 02155, USA. max.weisbuch@tufts.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20019288" target="_blank"〉PubMed〈/a〉

    Description: Pleuropulmonary blastoma (PPB) is a rare pediatric lung tumor that is often part of an inherited cancer syndrome. PPBs consist of mesenchymal cells that are susceptible to malignant transformation and cysts lined by epithelial cells. In a subset of patients, overgrowth of the cysts by mesenchymal cells leads to sarcoma formation. Here, we show that 11 multiplex PPB families harbor heterozygous germline mutations in DICER1, a gene encoding an endoribonuclease critical to the generation of small noncoding regulatory RNAs. Expression of DICER1 protein was undetectable in the epithelial component of PPB tumors but was retained in the malignant mesenchyme (sarcoma). We hypothesize that loss of DICER1 in the epithelium of the developing lung alters the regulation of diffusible factors that promote mesenchymal proliferation.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3098036/" 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/PMC3098036/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hill, D Ashley -- Ivanovich, Jennifer -- Priest, John R -- Gurnett, Christina A -- Dehner, Louis P -- Desruisseau, David -- Jarzembowski, Jason A -- Wikenheiser-Brokamp, Kathryn A -- Suarez, Brian K -- Whelan, Alison J -- Williams, Gretchen -- Bracamontes, Dawn -- Messinger, Yoav -- Goodfellow, Paul J -- P30 CA091842/CA/NCI NIH HHS/ -- P30 CA091842-07/CA/NCI NIH HHS/ -- P30 CA091842-08/CA/NCI NIH HHS/ -- R01 CA143167/CA/NCI NIH HHS/ -- R01 HL109265/HL/NHLBI NIH HHS/ -- UL1 RR024992/RR/NCRR NIH HHS/ -- New York, N.Y. -- Science. 2009 Aug 21;325(5943):965. doi: 10.1126/science.1174334.

    Description: Existing research reports inconsistent findings with regard to the effect of color on cognitive task performances. Some research suggests that blue or green leads to better performances than red; other studies record the opposite. Current work reconciles this discrepancy. We demonstrate that red (versus blue) color induces primarily an avoidance (versus approach) motivation (study 1, n = 69) and that red enhances performance on a detail-oriented task, whereas blue enhances performance on a creative task (studies 2 and 3, n = 208 and 118). Further, we replicate these results in the domains of product design (study 4, n = 42) and persuasive message evaluation (study 5, n = 161) and show that these effects occur outside of individuals' consciousness (study 6, n = 68). We also provide process evidence suggesting that the activation of alternative motivations mediates the effect of color on cognitive task performances.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Mehta, Ravi -- Zhu, Rui Juliet -- New York, N.Y. -- Science. 2009 Feb 27;323(5918):1226-9. doi: 10.1126/science.1169144.

    Description: Sexual conflict occurs when males and females act against each others' interest, typically resulting in selection favoring harmful males. We performed laboratory experiments on sexual conflict that both confined individuals in isolated groups, which prevents selection acting counter to this conflict, and provided more naturalistic multigroup population structures. We show that in water striders, aggressive male mating behavior was strongly favored within groups but not favored in a multigroup population when individuals can freely disperse among groups. These observations explain the persistence of less-aggressive males within natural populations.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Eldakar, Omar Tonsi -- Dlugos, Michael J -- Pepper, John W -- Wilson, David Sloan -- 5 K12 GM000708/GM/NIGMS NIH HHS/ -- K12 GM000708/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2009 Nov 6;326(5954):816. doi: 10.1126/science.1180183.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Center for Insect Science, University of Arizona, Tucson, AZ 85721, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19892974" target="_blank"〉PubMed〈/a〉

    Description: The familiar buzz of flying mosquitoes is an important mating signal, with the fundamental frequency of the female's flight tone signaling her presence. In the yellow fever and dengue vector Aedes aegypti, both sexes interact acoustically by shifting their flight tones to match, resulting in a courtship duet. Matching is made not at the fundamental frequency of 400 hertz (female) or 600 hertz (male) but at a shared harmonic of 1200 hertz, which exceeds the previously known upper limit of hearing in mosquitoes. Physiological recordings from Johnston's organ (the mosquito's "ear") reveal sensitivity up to 2000 hertz, consistent with our observed courtship behavior.

    Description: Commensal bacteria in the lower intestine of mammals are 10 times as numerous as the body's cells. We investigated the relative importance of different immune mechanisms in limiting the spread of the intestinal microbiota. Here, we reveal a flexible continuum between innate and adaptive immune function in containing commensal microbes. Mice deficient in critical innate immune functions such as Toll-like receptor signaling or oxidative burst production spontaneously produce high-titer serum antibodies against their commensal microbiota. These antibody responses are functionally essential to maintain host-commensal mutualism in vivo in the face of innate immune deficiency. Spontaneous hyper-activation of adaptive immunity against the intestinal microbiota, secondary to innate immune deficiency, may clarify the underlying mechanisms of inflammatory diseases where immune dysfunction is implicated.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3730530/" 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/PMC3730530/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Slack, Emma -- Hapfelmeier, Siegfried -- Stecher, Barbel -- Velykoredko, Yuliya -- Stoel, Maaike -- Lawson, Melissa A E -- Geuking, Markus B -- Beutler, Bruce -- Tedder, Thomas F -- Hardt, Wolf-Dietrich -- Bercik, Premysl -- Verdu, Elena F -- McCoy, Kathy D -- Macpherson, Andrew J -- AI56363/AI/NIAID NIH HHS/ -- CA105001/CA/NCI NIH HHS/ -- R01 CA105001/CA/NCI NIH HHS/ -- U19 AI056363/AI/NIAID NIH HHS/ -- New York, N.Y. -- Science. 2009 Jul 31;325(5940):617-20. doi: 10.1126/science.1172747.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Farncombe Family Digestive Health Research Institute, McMaster University, Hamilton, ON L8S 4L8, Canada. andrew.macpherson@insel.ch〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19644121" target="_blank"〉PubMed〈/a〉

    Description: Schizophrenia is a devastating, highly heritable brain disorder of unknown etiology. Recently, the first common genetic variant associated on a genome-wide level with schizophrenia and possibly bipolar disorder was discovered in ZNF804A (rs1344706). We show, by using an imaging genetics approach, that healthy carriers of rs1344706 risk genotypes exhibit no changes in regional activity but pronounced gene dosage-dependent alterations in functional coupling (correlated activity) of dorsolateral prefrontal cortex (DLPFC) across hemispheres and with hippocampus, mirroring findings in patients, and abnormal coupling of amygdala. Our findings establish disturbed connectivity as a neurogenetic risk mechanism for psychosis supported by genome-wide association, show that rs1344706 or variation in linkage disequilibrium is functional in human brain, and validate the intermediate phenotype strategy in psychiatry.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Esslinger, Christine -- Walter, Henrik -- Kirsch, Peter -- Erk, Susanne -- Schnell, Knut -- Arnold, Claudia -- Haddad, Leila -- Mier, Daniela -- Opitz von Boberfeld, Carola -- Raab, Kyeon -- Witt, Stephanie H -- Rietschel, Marcella -- Cichon, Sven -- Meyer-Lindenberg, Andreas -- New York, N.Y. -- Science. 2009 May 1;324(5927):605. doi: 10.1126/science.1167768.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Psychiatry and Psychotherapy, Central Institute of Mental Health, University of Heidelberg, J5, 68159 Mannheim, Germany.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19407193" target="_blank"〉PubMed〈/a〉

    Description: A major transition in evolution is the origin of a division between reproduction and work among individuals. Nowhere is this divide more striking than in social insects, where workers rarely produce offspring even though they are often capable of reproduction should the queen or king die. The molecular mechanisms that control worker reproduction remain largely unknown. We used a combination of behavioral assays and RNA interference (RNAi) to identify a gene required for the reproductive division of labor between the queen and the workers.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Korb, Judith -- Weil, Tobias -- Hoffmann, Katharina -- Foster, Kevin R -- Rehli, Michael -- New York, N.Y. -- Science. 2009 May 8;324(5928):758. doi: 10.1126/science.1170660.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Behavioral Biology, University of Osnabrueck, Barbarastrasse 11, D-49076 Osnabrueck, Germany. judith.korb@biologie.uni-osnabrueck.de〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19423819" target="_blank"〉PubMed〈/a〉

    Description: Hominid fossils predating the emergence of Australopithecus have been sparse and fragmentary. The evolution of our lineage after the last common ancestor we shared with chimpanzees has therefore remained unclear. Ardipithecus ramidus, recovered in ecologically and temporally resolved contexts in Ethiopia's Afar Rift, now illuminates earlier hominid paleobiology and aspects of extant African ape evolution. More than 110 specimens recovered from 4.4-million-year-old sediments include a partial skeleton with much of the skull, hands, feet, limbs, and pelvis. This hominid combined arboreal palmigrade clambering and careful climbing with a form of terrestrial bipedality more primitive than that of Australopithecus. Ar. ramidus had a reduced canine/premolar complex and a little-derived cranial morphology and consumed a predominantly C3 plant-based diet (plants using the C3 photosynthetic pathway). Its ecological habitat appears to have been largely woodland-focused. Ar. ramidus lacks any characters typical of suspension, vertical climbing, or knuckle-walking. Ar. ramidus indicates that despite the genetic similarities of living humans and chimpanzees, the ancestor we last shared probably differed substantially from any extant African ape. Hominids and extant African apes have each become highly specialized through very different evolutionary pathways. This evidence also illuminates the origins of orthogrady, bipedality, ecology, diet, and social behavior in earliest Hominidae and helps to define the basal hominid adaptation, thereby accentuating the derived nature of Australopithecus.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉White, Tim D -- Asfaw, Berhane -- Beyene, Yonas -- Haile-Selassie, Yohannes -- Lovejoy, C Owen -- Suwa, Gen -- WoldeGabriel, Giday -- New York, N.Y. -- Science. 2009 Oct 2;326(5949):75-86.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Human Evolution Research Center and Department of Integrative Biology, 3101 Valley Life Sciences Building, University of California, Berkeley, CA 94720, USA. timwhite@berkeley.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19810190" target="_blank"〉PubMed〈/a〉

    Description: Chronic viral infection is often associated with the dysfunction of virus-specific T cells. Our studies using Il21r-deficient (Il21r-/-) mice now suggest that interleukin-21 (IL-21) is critical for the long-term maintenance and functionality of CD8+ T cells and the control of chronic lymphocytic choriomeningitis virus infection in mice. Cell-autonomous IL-21 receptor (IL-21R)-dependent signaling by CD8+ T cells was required for sustained cell proliferation and cytokine production during chronic infection. Il21r-/- mice showed normal CD8+ T cell expansion, effector function, memory homeostasis, and recall responses during acute and after resolved infection with several other nonpersistent viruses. These data suggest that IL-21R signaling is required for the maintenance of polyfunctional T cells during chronic viral infections and have implications for understanding the immune response to other persisting antigens, such as tumors.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Frohlich, Anja -- Kisielow, Jan -- Schmitz, Iwana -- Freigang, Stefan -- Shamshiev, Abdijapar T -- Weber, Jacqueline -- Marsland, Benjamin J -- Oxenius, Annette -- Kopf, Manfred -- New York, N.Y. -- Science. 2009 Jun 19;324(5934):1576-80. doi: 10.1126/science.1172815.

    Description: Hybrid sterility of the heterogametic sex is one of the first postzygotic reproductive barriers to evolve during speciation, yet the molecular basis of hybrid sterility is poorly understood. We show that the hybrid male sterility gene Odysseus-site homeobox (OdsH) encodes a protein that localizes to evolutionarily dynamic loci within heterochromatin and leads to their decondensation. In Drosophila mauritiana x Drosophila simulans male hybrids, OdsH from D. mauritiana (OdsHmau) acts as a sterilizing factor by associating with the heterochromatic Y chromosome of D. simulans, whereas D. simulans OdsH (OdsHsim) does not. Characterization of sterile hybrid testes revealed that OdsH abundance and localization in the premeiotic phases of spermatogenesis differ between species. These results reveal that rapid heterochromatin evolution affects the onset of hybrid sterility.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2987944/" 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/PMC2987944/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bayes, Joshua J -- Malik, Harmit S -- R01 GM074108/GM/NIGMS NIH HHS/ -- R01 GM074108-05/GM/NIGMS NIH HHS/ -- R01-GM74108/GM/NIGMS NIH HHS/ -- T32 GM07270/GM/NIGMS NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2009 Dec 11;326(5959):1538-41. doi: 10.1126/science.1181756.

    Description: Precise wiring of the nervous system depends on coordinating the action of conserved families of proteins that direct axons to their appropriate targets. Slit-roundabout repulsion and netrin-deleted in colorectal cancer (DCC) (frazzled) attraction must be tightly regulated to control midline axon guidance in vertebrates and invertebrates, but the mechanism mediating this regulation is poorly defined. Here, we show that the Fra receptor has two genetically separable functions in regulating midline guidance in Drosophila. First, Fra mediates canonical chemoattraction in response to netrin, and, second, it functions independently of netrin to activate commissureless transcription, allowing attraction to be coupled to the down-regulation of repulsion in precrossing commissural axons.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4078765/" 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/PMC4078765/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Yang, Long -- Garbe, David S -- Bashaw, Greg J -- NS046333/NS/NINDS NIH HHS/ -- NS054739/NS/NINDS NIH HHS/ -- R01 NS046333/NS/NINDS NIH HHS/ -- R01 NS046333-07/NS/NINDS NIH HHS/ -- R01 NS054739/NS/NINDS NIH HHS/ -- R01 NS054739-03/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 2009 May 15;324(5929):944-7. doi: 10.1126/science.1171320.

    Description: Mitochondria continuously undergo two opposing processes, fission and fusion. The disruption of this dynamic equilibrium may herald cell injury or death and may contribute to developmental and neurodegenerative disorders. Nitric oxide functions as a signaling molecule, but in excess it mediates neuronal injury, in part via mitochondrial fission or fragmentation. However, the underlying mechanism for nitric oxide-induced pathological fission remains unclear. We found that nitric oxide produced in response to beta-amyloid protein, thought to be a key mediator of Alzheimer's disease, triggered mitochondrial fission, synaptic loss, and neuronal damage, in part via S-nitrosylation of dynamin-related protein 1 (forming SNO-Drp1).

    Description: To explore the mechanisms and evolution of cell-cycle control, we analyzed the position and conservation of large numbers of phosphorylation sites for the cyclin-dependent kinase Cdk1 in the budding yeast Saccharomyces cerevisiae. We combined specific chemical inhibition of Cdk1 with quantitative mass spectrometry to identify the positions of 547 phosphorylation sites on 308 Cdk1 substrates in vivo. Comparisons of these substrates with orthologs throughout the ascomycete lineage revealed that the position of most phosphorylation sites is not conserved in evolution; instead, clusters of sites shift position in rapidly evolving disordered regions. We propose that the regulation of protein function by phosphorylation often depends on simple nonspecific mechanisms that disrupt or enhance protein-protein interactions. The gain or loss of phosphorylation sites in rapidly evolving regions could facilitate the evolution of kinase-signaling circuits.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2813701/" 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/PMC2813701/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Holt, Liam J -- Tuch, Brian B -- Villen, Judit -- Johnson, Alexander D -- Gygi, Steven P -- Morgan, David O -- GM037049/GM/NIGMS NIH HHS/ -- GM50684/GM/NIGMS NIH HHS/ -- HG3456/HG/NHGRI NIH HHS/ -- R01 GM069901/GM/NIGMS NIH HHS/ -- R01 GM069901-06/GM/NIGMS NIH HHS/ -- R01 HG003456/HG/NHGRI NIH HHS/ -- R01 HG003456-06/HG/NHGRI NIH HHS/ -- New York, N.Y. -- Science. 2009 Sep 25;325(5948):1682-6. doi: 10.1126/science.1172867.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Departments of Physiology and Biochemistry and Biophysics, University of California, San Francisco, San Francisco, CA 94158, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19779198" target="_blank"〉PubMed〈/a〉

    Description: Two critical stages of mammalian oocyte regulation are prophase I arrest, which is important for sustaining the oocyte pool, and the progression through meiosis I (MI) to produce fertilizable eggs. We have found that the spindle assembly checkpoint protein BubR1 regulates both stages in mouse oocytes. We show that oocytes depleted of BubR1 cannot sustain prophase I arrest and readily undergo germinal vesicle breakdown, a marker for reentry into MI. BubR1-depleted oocytes then arrest before completing MI, marked by failure of polar body extrusion. Both meiotic defects in BubR1-depleted oocytes are due to reduced activity of the master regulator known as the anaphase-promoting complex (APC), brought about through diminished levels of the APC coactivator Cdh1.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3428834/" 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/PMC3428834/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Homer, Hayden -- Gui, Liming -- Carroll, John -- 082587/Wellcome Trust/United Kingdom -- 082587/Z/07/Z/Wellcome Trust/United Kingdom -- G0400530/Medical Research Council/United Kingdom -- Medical Research Council/United Kingdom -- New York, N.Y. -- Science. 2009 Nov 13;326(5955):991-4. doi: 10.1126/science.1175326.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Oocyte and Embryo Research Laboratory, Department of Cell and Developmental Biology, Division of Biosciences and Institute for Women's Health, University College London, London, UK. h.homer@ucl.ac.uk〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19965510" target="_blank"〉PubMed〈/a〉

    Description: Like many species, the model plant Arabidopsis thaliana exhibits multiple different life histories in natural environments. We grew mutants impaired in different signaling pathways in field experiments across the species' native European range in order to dissect the mechanisms underlying this variation. Unexpectedly, mutational loss at loci implicated in the cold requirement for flowering had little effect on life history except in late-summer cohorts. A genetically informed photothermal model of progression toward flowering explained most of the observed variation and predicted an abrupt transition from autumn flowering to spring flowering in late-summer germinants. Environmental signals control the timing of this transition, creating a critical window of acute sensitivity to genetic and climatic change that may be common for seasonally regulated life history traits.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wilczek, Amity M -- Roe, Judith L -- Knapp, Mary C -- Cooper, Martha D -- Lopez-Gallego, Cristina -- Martin, Laura J -- Muir, Christopher D -- Sim, Sheina -- Walker, Alexis -- Anderson, Jillian -- Egan, J Franklin -- Moyers, Brook T -- Petipas, Renee -- Giakountis, Antonis -- Charbit, Erika -- Coupland, George -- Welch, Stephen M -- Schmitt, Johanna -- New York, N.Y. -- Science. 2009 Feb 13;323(5916):930-4. doi: 10.1126/science.1165826.

    Description: Patten recognition receptors, which recognize pathogens or components of injured cells (danger), trigger activation of the innate immune system. Whether and how the host distinguishes between danger- versus pathogen-associated molecular patterns remains unresolved. We report that CD24-deficient mice exhibit increased susceptibility to danger- but not pathogen-associated molecular patterns. CD24 associates with high mobility group box 1, heat shock protein 70, and heat shock protein 90; negatively regulates their stimulatory activity; and inhibits nuclear factor kappaB (NF-kappaB) activation. This occurs at least in part through CD24 association with Siglec-10 in humans or Siglec-G in mice. Our results reveal that the CD24-Siglec G pathway protects the host against a lethal response to pathological cell death and discriminates danger- versus pathogen-associated molecular patterns.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2765686/" 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/PMC2765686/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Chen, Guo-Yun -- Tang, Jie -- Zheng, Pan -- Liu, Yang -- AI064350/AI/NIAID NIH HHS/ -- CA112001/CA/NCI NIH HHS/ -- CA58033/CA/NCI NIH HHS/ -- R01 AI064350/AI/NIAID NIH HHS/ -- R01 AI064350-04/AI/NIAID NIH HHS/ -- R01 CA058033/CA/NCI NIH HHS/ -- R01 CA058033-16A2/CA/NCI NIH HHS/ -- R01 CA112001/CA/NCI NIH HHS/ -- R01 CA112001-02/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 2009 Mar 27;323(5922):1722-5. doi: 10.1126/science.1168988.

    Description: Amyotrophic lateral sclerosis (ALS) is a fatal degenerative motor neuron disorder. Ten percent of cases are inherited; most involve unidentified genes. We report here 13 mutations in the fused in sarcoma/translated in liposarcoma (FUS/TLS) gene on chromosome 16 that were specific for familial ALS. The FUS/TLS protein binds to RNA, functions in diverse processes, and is normally located predominantly in the nucleus. In contrast, the mutant forms of FUS/TLS accumulated in the cytoplasm of neurons, a pathology that is similar to that of the gene TAR DNA-binding protein 43 (TDP43), whose mutations also cause ALS. Neuronal cytoplasmic protein aggregation and defective RNA metabolism thus appear to be common pathogenic mechanisms involved in ALS and possibly in other neurodegenerative disorders.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kwiatkowski, T J Jr -- Bosco, D A -- Leclerc, A L -- Tamrazian, E -- Vanderburg, C R -- Russ, C -- Davis, A -- Gilchrist, J -- Kasarskis, E J -- Munsat, T -- Valdmanis, P -- Rouleau, G A -- Hosler, B A -- Cortelli, P -- de Jong, P J -- Yoshinaga, Y -- Haines, J L -- Pericak-Vance, M A -- Yan, J -- Ticozzi, N -- Siddique, T -- McKenna-Yasek, D -- Sapp, P C -- Horvitz, H R -- Landers, J E -- Brown, R H Jr -- New York, N.Y. -- Science. 2009 Feb 27;323(5918):1205-8. doi: 10.1126/science.1166066.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Neurology, Massachusetts General Hospital, 114 16th Street, Charlestown, MA 02129, USA. tkwiatkowski@partners.org〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19251627" target="_blank"〉PubMed〈/a〉

    Description: Although the nematode Caenorhabditis elegans produces self-fertile hermaphrodites, it descended from a male/female species, so hermaphroditism provides a model for the origin of novel traits. In the related species C. remanei, which has only male and female sexes, lowering the activity of tra-2 by RNA interference created XX animals that made spermatids as well as oocytes, but their spermatids could not activate without the addition of male seminal fluid. However, by lowering the expression of both tra-2 and swm-1, a gene that regulates sperm activation in C. elegans, we produced XX animals with active sperm that were self-fertile. Thus, the evolution of hermaphroditism in Caenorhabditis probably required two steps: a mutation in the sex-determination pathway that caused XX spermatogenesis and a mutation that allowed these spermatids to self-activate.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Baldi, Chris -- Cho, Soochin -- Ellis, Ronald E -- New York, N.Y. -- Science. 2009 Nov 13;326(5955):1002-5. doi: 10.1126/science.1176013.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Graduate School of Biomedical Sciences, University of Medicine and Dentistry of New Jersey, Stratford, NJ 08084, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19965511" target="_blank"〉PubMed〈/a〉

    Description: The Hedgehog (Hh) signaling pathway is inappropriately activated in certain human cancers, including medulloblastoma, an aggressive brain tumor. GDC-0449, a drug that inhibits Hh signaling by targeting the serpentine receptor Smoothened (SMO), has produced promising anti-tumor responses in early clinical studies of cancers driven by mutations in this pathway. To evaluate the mechanism of resistance in a medulloblastoma patient who had relapsed after an initial response to GDC-0449, we determined the mutational status of Hh signaling genes in the tumor after disease progression. We identified an amino acid substitution at a conserved aspartic acid residue of SMO that had no effect on Hh signaling but disrupted the ability of GDC-0449 to bind SMO and suppress this pathway. A mutation altering the same amino acid also arose in a GDC-0449-resistant mouse model of medulloblastoma. These findings show that acquired mutations in a serpentine receptor with features of a G protein-coupled receptor can serve as a mechanism of drug resistance in human cancer.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Yauch, Robert L -- Dijkgraaf, Gerrit J P -- Alicke, Bruno -- Januario, Thomas -- Ahn, Christina P -- Holcomb, Thomas -- Pujara, Kanan -- Stinson, Jeremy -- Callahan, Christopher A -- Tang, Tracy -- Bazan, J Fernando -- Kan, Zhengyan -- Seshagiri, Somasekar -- Hann, Christine L -- Gould, Stephen E -- Low, Jennifer A -- Rudin, Charles M -- de Sauvage, Frederic J -- New York, N.Y. -- Science. 2009 Oct 23;326(5952):572-4. doi: 10.1126/science.1179386.

    Description: The evolution of cis regulatory elements (enhancers) of developmentally regulated genes plays a large role in the evolution of animal morphology. However, the mutational path of enhancer evolution--the number, origin, effect, and order of mutations that alter enhancer function--has not been elucidated. Here, we localized a suite of substitutions in a modular enhancer of the ebony locus responsible for adaptive melanism in a Ugandan Drosophila population. We show that at least five mutations with varied effects arose recently from a combination of standing variation and new mutations and combined to create an allele of large phenotypic effect. We underscore how enhancers are distinct macromolecular entities, subject to fundamentally different, and generally more relaxed, functional constraints relative to protein sequences.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3363996/" 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/PMC3363996/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Rebeiz, Mark -- Pool, John E -- Kassner, Victoria A -- Aquadro, Charles F -- Carroll, Sean B -- F32GM78972/GM/NIGMS NIH HHS/ -- F32HG004182/HG/NHGRI NIH HHS/ -- GM036431/GM/NIGMS NIH HHS/ -- R01 GM036431/GM/NIGMS NIH HHS/ -- R01 GM036431-22/GM/NIGMS NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2009 Dec 18;326(5960):1663-7. doi: 10.1126/science.1178357.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Howard Hughes Medical Institute and Laboratory of Molecular Biology, University of Wisconsin, Madison, WI 53706, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20019281" target="_blank"〉PubMed〈/a〉

    Description: To understand basic principles of bacterial metabolism organization and regulation, but also the impact of genome size, we systematically studied one of the smallest bacteria, Mycoplasma pneumoniae. A manually curated metabolic network of 189 reactions catalyzed by 129 enzymes allowed the design of a defined, minimal medium with 19 essential nutrients. More than 1300 growth curves were recorded in the presence of various nutrient concentrations. Measurements of biomass indicators, metabolites, and 13C-glucose experiments provided information on directionality, fluxes, and energetics; integration with transcription profiling enabled the global analysis of metabolic regulation. Compared with more complex bacteria, the M. pneumoniae metabolic network has a more linear topology and contains a higher fraction of multifunctional enzymes; general features such as metabolite concentrations, cellular energetics, adaptability, and global gene expression responses are similar, however.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Yus, Eva -- Maier, Tobias -- Michalodimitrakis, Konstantinos -- van Noort, Vera -- Yamada, Takuji -- Chen, Wei-Hua -- Wodke, Judith A H -- Guell, Marc -- Martinez, Sira -- Bourgeois, Ronan -- Kuhner, Sebastian -- Raineri, Emanuele -- Letunic, Ivica -- Kalinina, Olga V -- Rode, Michaela -- Herrmann, Richard -- Gutierrez-Gallego, Ricardo -- Russell, Robert B -- Gavin, Anne-Claude -- Bork, Peer -- Serrano, Luis -- New York, N.Y. -- Science. 2009 Nov 27;326(5957):1263-8. doi: 10.1126/science.1177263.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Centre for Genomic Regulation (CRG) and Universitat Pompeu Fabra, Avenida Dr. Aiguader 88, 08003 Barcelona, Spain.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19965476" target="_blank"〉PubMed〈/a〉

    Description: Colonization of the land by plants most likely occurred in a stepwise fashion starting in the Mid-Ordovician. The earliest flora of bryophyte-like plants appears to have been cosmopolitan and dominated the planet, relatively unchanged, for some 30 million years. It is represented by fossilized dispersed cryptospores and fragmentary plant remains. In the Early Silurian, cryptospore abundance and diversity diminished abruptly as trilete spores appeared, became abundant, and underwent rapid diversification. This change coincides approximately with the appearance of vascular plant megafossils and probably represents the origin and adaptive radiation of vascular plants. We have obtained a diverse trilete spore occurrence from the Late Ordovician that suggests that vascular plants originated and diversified earlier than previously hypothesized, in Gondwana, before migrating elsewhere and secondarily diversifying.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Steemans, Philippe -- Herisse, Alain Le -- Melvin, John -- Miller, Merrell A -- Paris, Florentin -- Verniers, Jacques -- Wellman, Charles H -- New York, N.Y. -- Science. 2009 Apr 17;324(5925):353. doi: 10.1126/science.1169659.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Palaeobotany, B-18, University of Liege, 4000 Liege, Belgium.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19372423" target="_blank"〉PubMed〈/a〉

    Description: The brain's sensitivity to unexpected outcomes plays a fundamental role in an organism's ability to adapt and learn new behaviors. Emerging research suggests that midbrain dopaminergic neurons encode these unexpected outcomes. We used microelectrode recordings during deep brain stimulation surgery to study neuronal activity in the human substantia nigra (SN) while patients with Parkinson's disease engaged in a probabilistic learning task motivated by virtual financial rewards. Based on a model of the participants' expected reward, we divided trial outcomes into expected and unexpected gains and losses. SN neurons exhibited significantly higher firing rates after unexpected gains than unexpected losses. No such differences were observed after expected gains and losses. This result provides critical support for the hypothesized role of the SN in human reinforcement learning.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2839450/" 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/PMC2839450/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Zaghloul, Kareem A -- Blanco, Justin A -- Weidemann, Christoph T -- McGill, Kathryn -- Jaggi, Jurg L -- Baltuch, Gordon H -- Kahana, Michael J -- MH062196/MH/NIMH NIH HHS/ -- MH61975/MH/NIMH NIH HHS/ -- P50 MH062196/MH/NIMH NIH HHS/ -- P50 MH062196-090008/MH/NIMH NIH HHS/ -- R01 MH061975/MH/NIMH NIH HHS/ -- R01 MH061975-08/MH/NIMH NIH HHS/ -- R01 NS048598/NS/NINDS NIH HHS/ -- R01 NS048598-04/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 2009 Mar 13;323(5920):1496-9. doi: 10.1126/science.1167342.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Neurosurgery, University of Pennsylvania, Philadelphia, PA 19104, USA. zaghlouk@uphs.upenn.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19286561" target="_blank"〉PubMed〈/a〉

    Description: Virtually all of the 560 human proteases are stored as inactive proenyzmes and are strictly regulated. We report the identification and characterization of the first small molecules that directly activate proenzymes, the apoptotic procaspases-3 and -6. It is surprising that these compounds induce autoproteolytic activation by stabilizing a conformation that is both more active and more susceptible to intermolecular proteolysis. These procaspase activators bypass the normal upstream proapoptotic signaling cascades and induce rapid apoptosis in a variety of cell lines. Systematic biochemical and biophysical analyses identified a cluster of mutations in procaspase-3 that resist small-molecule activation both in vitro and in cells. Compounds that induce gain of function are rare, and the activators reported here will enable direct control of the executioner caspases in apoptosis and in cellular differentiation. More generally, these studies presage the discovery of other proenzyme activators to explore fundamental processes of proenzyme activation and their fate-determining roles in biology.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2886848/" 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/PMC2886848/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wolan, Dennis W -- Zorn, Julie A -- Gray, Daniel C -- Wells, James A -- F32 CA119641/CA/NCI NIH HHS/ -- F32 CA119641-03/CA/NCI NIH HHS/ -- R01 CA136779/CA/NCI NIH HHS/ -- R21 N5057022/PHS HHS/ -- New York, N.Y. -- Science. 2009 Nov 6;326(5954):853-8. doi: 10.1126/science.1177585.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Pharmaceutical Chemistry, University of California, San Francisco, Byers Hall, 1700 4th Street, San Francisco, CA 94158, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19892984" target="_blank"〉PubMed〈/a〉

    Description: We tested whether classroom activities that encourage students to connect course materials to their lives will increase student motivation and learning. We hypothesized that this effect will be stronger for students who have low expectations of success. In a randomized field experiment with high school students, we found that a relevance intervention, which encouraged students to make connections between their lives and what they were learning in their science courses, increased interest in science and course grades for students with low success expectations. The results have implications for the development of science curricula and theories of motivation.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hulleman, Chris S -- Harackiewicz, Judith M -- New York, N.Y. -- Science. 2009 Dec 4;326(5958):1410-2. doi: 10.1126/science.1177067.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Graduate Psychology, James Madison University, Harrisonburg, VA 22807, USA. hullemcs@jmu.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19965759" target="_blank"〉PubMed〈/a〉

    Description: Effective B cell-mediated immunity and antibody responses often require help from CD4+ T cells. It is thought that a distinct CD4+ effector T cell subset, called T follicular helper cells (T(FH)), provides this help; however, the molecular requirements for T(FH) differentiation are unknown. We found that expression of the transcription factor Bcl6 in CD4+ T cells is both necessary and sufficient for in vivo T(FH) differentiation and T cell help to B cells in mice. In contrast, the transcription factor Blimp-1, an antagonist of Bcl6, inhibits T(FH) differentiation and help, thereby preventing B cell germinal center and antibody responses. These findings demonstrate that T(FH) cells are required for proper B cell responses in vivo and that Bcl6 and Blimp-1 play central but opposing roles in T(FH) differentiation.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2766560/" 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/PMC2766560/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Johnston, Robert J -- Poholek, Amanda C -- DiToro, Daniel -- Yusuf, Isharat -- Eto, Danelle -- Barnett, Burton -- Dent, Alexander L -- Craft, Joe -- Crotty, Shane -- AR40072/AR/NIAMS NIH HHS/ -- AR44076/AR/NIAMS NIH HHS/ -- P30 AR053495/AR/NIAMS NIH HHS/ -- R01 063107/PHS HHS/ -- R01 072543/PHS HHS/ -- R01 AI063107/AI/NIAID NIH HHS/ -- R01 AI063107-01A1/AI/NIAID NIH HHS/ -- R01 AI072543/AI/NIAID NIH HHS/ -- R01 AI072543-01A1/AI/NIAID NIH HHS/ -- New York, N.Y. -- Science. 2009 Aug 21;325(5943):1006-10. doi: 10.1126/science.1175870.

    Description: Evolution may be dominated by biotic factors, as in the Red Queen model, or abiotic factors, as in the Court Jester model, or a mixture of both. The two models appear to operate predominantly over different geographic and temporal scales: Competition, predation, and other biotic factors shape ecosystems locally and over short time spans, but extrinsic factors such as climate and oceanographic and tectonic events shape larger-scale patterns regionally and globally, and through thousands and millions of years. Paleobiological studies suggest that species diversity is driven largely by abiotic factors such as climate, landscape, or food supply, and comparative phylogenetic approaches offer new insights into clade dynamics.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Benton, Michael J -- New York, N.Y. -- Science. 2009 Feb 6;323(5915):728-32. doi: 10.1126/science.1157719.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Earth Sciences, University of Bristol, Bristol BS8 1RJ, UK. mike.benton@bristol.ac.uk〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19197051" target="_blank"〉PubMed〈/a〉

    Description: The dentate gyrus (DG) of the mammalian hippocampus is hypothesized to mediate pattern separation-the formation of distinct and orthogonal representations of mnemonic information-and also undergoes neurogenesis throughout life. How neurogenesis contributes to hippocampal function is largely unknown. Using adult mice in which hippocampal neurogenesis was ablated, we found specific impairments in spatial discrimination with two behavioral assays: (i) a spatial navigation radial arm maze task and (ii) a spatial, but non-navigable, task in the mouse touch screen. Mice with ablated neurogenesis were impaired when stimuli were presented with little spatial separation, but not when stimuli were more widely separated in space. Thus, newborn neurons may be necessary for normal pattern separation function in the DG of adult mice.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2997634/" 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/PMC2997634/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Clelland, C D -- Choi, M -- Romberg, C -- Clemenson, G D Jr -- Fragniere, A -- Tyers, P -- Jessberger, S -- Saksida, L M -- Barker, R A -- Gage, F H -- Bussey, T J -- NS-050217/NS/NINDS NIH HHS/ -- R01 NS050217/NS/NINDS NIH HHS/ -- R01 NS050217-05/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 2009 Jul 10;325(5937):210-3. doi: 10.1126/science.1173215.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratory of Genetics, 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/19590004" target="_blank"〉PubMed〈/a〉

    Description: Ever since the integration of Mendelian genetics into evolutionary biology in the early 20th century, evolutionary geneticists have for the most part treated genes and mutations as generic entities. However, recent observations indicate that all genes are not equal in the eyes of evolution. Evolutionarily relevant mutations tend to accumulate in hotspot genes and at specific positions within genes. Genetic evolution is constrained by gene function, the structure of genetic networks, and population biology. The genetic basis of evolution may be predictable to some extent, and further understanding of this predictability requires incorporation of the specific functions and characteristics of genes into evolutionary theory.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3184636/" 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/PMC3184636/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Stern, David L -- Orgogozo, Virginie -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2009 Feb 6;323(5915):746-51. doi: 10.1126/science.1158997.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Ecology and Evolutionary Biology, Howard Hughes Medical Institute, Princeton University, Princeton, NJ 08544, USA. dstern@princeton.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19197055" target="_blank"〉PubMed〈/a〉

    Description: Picoeukaryotes are a taxonomically diverse group of organisms less than 2 micrometers in diameter. Photosynthetic marine picoeukaryotes in the genus Micromonas thrive in ecosystems ranging from tropical to polar and could serve as sentinel organisms for biogeochemical fluxes of modern oceans during climate change. These broadly distributed primary producers belong to an anciently diverged sister clade to land plants. Although Micromonas isolates have high 18S ribosomal RNA gene identity, we found that genomes from two isolates shared only 90% of their predicted genes. Their independent evolutionary paths were emphasized by distinct riboswitch arrangements as well as the discovery of intronic repeat elements in one isolate, and in metagenomic data, but not in other genomes. Divergence appears to have been facilitated by selection and acquisition processes that actively shape the repertoire of genes that are mutually exclusive between the two isolates differently than the core genes. Analyses of the Micromonas genomes offer valuable insights into ecological differentiation and the dynamic nature of early plant evolution.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Worden, Alexandra Z -- Lee, Jae-Hyeok -- Mock, Thomas -- Rouze, Pierre -- Simmons, Melinda P -- Aerts, Andrea L -- Allen, Andrew E -- Cuvelier, Marie L -- Derelle, Evelyne -- Everett, Meredith V -- Foulon, Elodie -- Grimwood, Jane -- Gundlach, Heidrun -- Henrissat, Bernard -- Napoli, Carolyn -- McDonald, Sarah M -- Parker, Micaela S -- Rombauts, Stephane -- Salamov, Aasf -- Von Dassow, Peter -- Badger, Jonathan H -- Coutinho, Pedro M -- Demir, Elif -- Dubchak, Inna -- Gentemann, Chelle -- Eikrem, Wenche -- Gready, Jill E -- John, Uwe -- Lanier, William -- Lindquist, Erika A -- Lucas, Susan -- Mayer, Klaus F X -- Moreau, Herve -- Not, Fabrice -- Otillar, Robert -- Panaud, Olivier -- Pangilinan, Jasmyn -- Paulsen, Ian -- Piegu, Benoit -- Poliakov, Aaron -- Robbens, Steven -- Schmutz, Jeremy -- Toulza, Eve -- Wyss, Tania -- Zelensky, Alexander -- Zhou, Kemin -- Armbrust, E Virginia -- Bhattacharya, Debashish -- Goodenough, Ursula W -- Van de Peer, Yves -- Grigoriev, Igor V -- New York, N.Y. -- Science. 2009 Apr 10;324(5924):268-72. doi: 10.1126/science.1167222.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Monterey Bay Aquarium Research Institute, Moss Landing, CA 95039 USA. azworden@mbari.org〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19359590" target="_blank"〉PubMed〈/a〉

    Description: A major cause for biodiversity may be biodiversity itself. As new species form, they may create new niches for others to exploit, potentially catalyzing a chain reaction of speciation events across trophic levels. We tested for such sequential radiation in the Rhagoletis pomonella (Diptera: Tephritidae) complex, a model for sympatric speciation via host plant shifting. We report that the parasitic wasp Diachasma alloeum (Hymenoptera: Braconidae) has formed new incipient species as a result of specializing on diversifying fly hosts, including the recently derived apple-infesting race of R. pomonella. Furthermore, we show that traits that differentially adapt R. pomonella flies to their host plants have also quickly evolved and serve as ecological barriers to reproduction, isolating the wasps. Speciation therefore cascades as the effects of new niche construction move across trophic levels.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Forbes, Andrew A -- Powell, Thomas H Q -- Stelinski, Lukasz L -- Smith, James J -- Feder, Jeffrey L -- New York, N.Y. -- Science. 2009 Feb 6;323(5915):776-9. doi: 10.1126/science.1166981.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biological Sciences, University of Notre Dame, Galvin Life Sciences Building, Notre Dame, IN 46556, USA. aaforbes@ucdavis.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19197063" target="_blank"〉PubMed〈/a〉

    Description: Expression and signaling of CD30, a tumor necrosis factor receptor family member, is up-regulated in numerous lymphoid-derived neoplasias, most notably anaplastic large-cell lymphoma (ALCL) and Hodgkin's lymphoma. To gain insight into the mechanism of CD30 signaling, we used an affinity purification strategy that led to the identification of the aryl hydrocarbon receptor nuclear translocator (ARNT) as a CD30-interacting protein that modulated the activity of the RelB subunit of the transcription factor nuclear factor kappaB (NF-kappaB). ALCL cells that were deficient in ARNT exhibited defects in RelB recruitment to NF-kappaB-responsive promoters, whereas RelA recruitment to the same sites was potentiated, resulting in the augmented expression of these NF-kappaB-responsive genes. These findings indicate that ARNT functions in concert with RelB in a CD30-induced negative feedback mechanism.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2682336/" 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/PMC2682336/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wright, Casey W -- Duckett, Colin S -- R01 GM067827/GM/NIGMS NIH HHS/ -- R01 GM067827-04/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2009 Jan 9;323(5911):251-5. doi: 10.1126/science.1162818.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Pathology, University of Michigan Medical School, Ann Arbor, MI 48109, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19131627" target="_blank"〉PubMed〈/a〉

    Description: The head and mouthpart structures of 11 species of Eurasian scorpionflies represent three extinct and closely related families during a 62-million-year interval from the late Middle Jurassic to the late Early Cretaceous. These taxa had elongate, siphonate (tubular) proboscides and fed on ovular secretions of extinct gymnosperms. Five potential ovulate host-plant taxa co-occur with these insects: a seed fern, conifer, ginkgoopsid, pentoxylalean, and gnetalean. The presence of scorpionfly taxa suggests that siphonate proboscides fed on gymnosperm pollination drops and likely engaged in pollination mutualisms with gymnosperms during the mid-Mesozoic, long before the similar and independent coevolution of nectar-feeding flies, moths, and beetles on angiosperms. All three scorpionfly families became extinct during the later Early Cretaceous, coincident with global gymnosperm-to-angiosperm turnover.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2944650/" 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/PMC2944650/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ren, Dong -- Labandeira, Conrad C -- Santiago-Blay, Jorge A -- Rasnitsyn, Alexandr -- Shih, ChungKun -- Bashkuev, Alexei -- Logan, M Amelia V -- Hotton, Carol L -- Dilcher, David -- Z99 LM999999/Intramural NIH HHS/ -- New York, N.Y. -- Science. 2009 Nov 6;326(5954):840-7. doi: 10.1126/science.1178338.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉College of Life Sciences, Capital Normal University, Beijing 100048, China.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19892981" target="_blank"〉PubMed〈/a〉

    Description: Plants possess inducible systemic defense responses when locally infected by pathogens. Bacterial infection results in the increased accumulation of the mobile metabolite azelaic acid, a nine-carbon dicarboxylic acid, in the vascular sap of Arabidopsis that confers local and systemic resistance against the pathogen Pseudomonas syringae. Azelaic acid primes plants to accumulate salicylic acid (SA), a known defense signal, upon infection. Mutation of the AZELAIC ACID INDUCED 1 (AZI1) gene, which is induced by azelaic acid, results in the specific loss of systemic immunity triggered by pathogen or azelaic acid and of the priming of SA induction in plants. Furthermore, the predicted secreted protein AZI1 is also important for generating vascular sap that confers disease resistance. Thus, azelaic acid and AZI1 are components of plant systemic immunity involved in priming defenses.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Jung, Ho Won -- Tschaplinski, Timothy J -- Wang, Lin -- Glazebrook, Jane -- Greenberg, Jean T -- New York, N.Y. -- Science. 2009 Apr 3;324(5923):89-91. doi: 10.1126/science.1170025.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Molecular Genetics and Cell Biology, University of Chicago, 1103 East 57th Street EBC410, Chicago, IL 60637, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19342588" target="_blank"〉PubMed〈/a〉

    Description: Biologists have long been fascinated by the exceptionally high diversity displayed by some evolutionary groups. Adaptive radiation in such clades is not only spectacular, but is also an extremely complex process influenced by a variety of ecological, genetic, and developmental factors and strongly dependent on historical contingencies. Using modeling approaches, we identify 10 general patterns concerning the temporal, spatial, and genetic/morphological properties of adaptive radiation. Some of these are strongly supported by empirical work, whereas for others, empirical support is more tentative. In almost all cases, more data are needed. Future progress in our understanding of adaptive radiation will be most successful if theoretical and empirical approaches are integrated, as has happened in other areas of evolutionary biology.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gavrilets, Sergey -- Losos, Jonathan B -- GM56693/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2009 Feb 6;323(5915):732-7. doi: 10.1126/science.1157966.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Ecology, National Institute for Mathematical and Biological Synthesis, University of Tennessee, Knoxville, TN 37996, USA. sergey@tiem.utk.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19197052" target="_blank"〉PubMed〈/a〉

    Description: The extracellular matrix (ECM) and ECM proteins are important in phenomena as diverse as developmental patterning, stem cell niches, cancer, and genetic diseases. The ECM has many effects beyond providing structural support. ECM proteins typically include multiple, independently folded domains whose sequences and arrangement are highly conserved. Some of these domains bind adhesion receptors such as integrins that mediate cell-matrix adhesion and also transduce signals into cells. However, ECM proteins also bind soluble growth factors and regulate their distribution, activation, and presentation to cells. As organized, solid-phase ligands, ECM proteins can integrate complex, multivalent signals to cells in a spatially patterned and regulated fashion. These properties need to be incorporated into considerations of the functions of the ECM.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3536535/" 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/PMC3536535/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hynes, Richard O -- P01 HL066105/HL/NHLBI NIH HHS/ -- R01 CA017007/CA/NCI NIH HHS/ -- U54 CA126515/CA/NCI NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2009 Nov 27;326(5957):1216-9. doi: 10.1126/science.1176009.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Howard Hughes Medical Institute, David H.

    Description: Sensory information detected by the peripheral nervous system is represented as a topographic map in the brain. It has long been thought that the topography of the map is determined by graded positional cues that are expressed by the target. Here, we analyzed the pre-target axon sorting for olfactory map formation in mice. In olfactory sensory neurons, an axon guidance receptor, Neuropilin-1, and its repulsive ligand, Semaphorin-3A, are expressed in a complementary manner. We found that expression levels of Neuropilin-1 determined both pre-target sorting and projection sites of axons. Olfactory sensory neuron-specific knockout of Semaphorin-3A perturbed axon sorting and altered the olfactory map topography. Thus, pre-target axon sorting plays an important role in establishing the topographic order based on the relative levels of guidance molecules expressed by axons.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Imai, Takeshi -- Yamazaki, Takahiro -- Kobayakawa, Reiko -- Kobayakawa, Ko -- Abe, Takaya -- Suzuki, Misao -- Sakano, Hitoshi -- New York, N.Y. -- Science. 2009 Jul 31;325(5940):585-90. doi: 10.1126/science.1173596.

    Description: An emerging set of methods enables an experimental dialogue with biological systems composed of many interacting cell types--in particular, with neural circuits in the brain. These methods are sometimes called "optogenetic" because they use light-responsive proteins ("opto-") encoded in DNA ("-genetic"). Optogenetic devices can be introduced into tissues or whole organisms by genetic manipulation and be expressed in anatomically or functionally defined groups of cells. Two kinds of devices perform complementary functions: Light-driven actuators control electrochemical signals, while light-emitting sensors report them. Actuators pose questions by delivering targeted perturbations; sensors (and other measurements) signal answers. These catechisms are beginning to yield previously unattainable insight into the organization of neural circuits, the regulation of their collective dynamics, and the causal relationships between cellular activity patterns and behavior.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Miesenbock, Gero -- G0700888/Medical Research Council/United Kingdom -- G0701225/Medical Research Council/United Kingdom -- Medical Research Council/United Kingdom -- New York, N.Y. -- Science. 2009 Oct 16;326(5951):395-9. doi: 10.1126/science.1174520.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Physiology, Anatomy and Genetics, University of Oxford, Parks Road, Oxford, OX1 3PT, UK. gero.miesenboeck@dpag.ox.ac.uk〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19833960" target="_blank"〉PubMed〈/a〉

    Description: A single-base pair resolution silkworm genetic variation map was constructed from 40 domesticated and wild silkworms, each sequenced to approximately threefold coverage, representing 99.88% of the genome. We identified ~16 million single-nucleotide polymorphisms, many indels, and structural variations. We find that the domesticated silkworms are clearly genetically differentiated from the wild ones, but they have maintained large levels of genetic variability, suggesting a short domestication event involving a large number of individuals. We also identified signals of selection at 354 candidate genes that may have been important during domestication, some of which have enriched expression in the silk gland, midgut, and testis.

    Description: Many species of parasitoid wasps inject polydnavirus particles in order to manipulate host defenses and development. Because the DNA packaged in these particles encodes almost no viral structural proteins, their relation to viruses has been debated. Characterization of complementary DNAs derived from braconid wasp ovaries identified genes encoding subunits of a viral RNA polymerase and structural components of polydnavirus particles related most closely to those of nudiviruses--a sister group of baculoviruses. The conservation of this viral machinery in different braconid wasp lineages sharing polydnaviruses suggests that parasitoid wasps incorporated a nudivirus-related genome into their own genetic material. We found that the nudiviral genes themselves are no longer packaged but are actively transcribed and produce particles used to deliver genes essential for successful parasitism in lepidopteran hosts.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bezier, Annie -- Annaheim, Marc -- Herbiniere, Juline -- Wetterwald, Christoph -- Gyapay, Gabor -- Bernard-Samain, Sylvie -- Wincker, Patrick -- Roditi, Isabel -- Heller, Manfred -- Belghazi, Maya -- Pfister-Wilhem, Rita -- Periquet, Georges -- Dupuy, Catherine -- Huguet, Elisabeth -- Volkoff, Anne-Nathalie -- Lanzrein, Beatrice -- Drezen, Jean-Michel -- New York, N.Y. -- Science. 2009 Feb 13;323(5916):926-30. doi: 10.1126/science.1166788.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Institut de Recherche sur la Biologie de l'Insecte, CNRS UMR 6035, Universite Francois Rabelais, Parc de Grandmont, 37200 Tours, France.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19213916" target="_blank"〉PubMed〈/a〉

    Description: Environmental perturbations during mass extinctions were likely manifested differently in epicontinental seas than in open-ocean-facing habitats of comparable depth. Here, we present a dissection of origination and extinction in epicontinental seas versus open-ocean-facing coastal regions in the Permian through Cretaceous periods, an interval through which both settings are well represented in the fossil record. Results demonstrate that extinction rates were significantly higher in open-ocean settings than in epicontinental seas during major mass extinctions but not at other times and that origination rates were significantly higher in open-ocean settings for a protracted interval from the Late Jurassic through the Late Cretaceous. These patterns are manifested even when other paleogeographic and environmental variables are held fixed, indicating that epicontinental seas and open-ocean-facing coastlines carry distinct macroevolutionary signatures.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Miller, Arnold I -- Foote, Michael -- New York, N.Y. -- Science. 2009 Nov 20;326(5956):1106-9. doi: 10.1126/science.1180061.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Geology, University of Cincinnati, Post Office Box 210013, Cincinnati, OH 45221, USA. arnold.miller@uc.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19965428" target="_blank"〉PubMed〈/a〉

    Description: Holometabolous insects undergo complete metamorphosis to become sexually mature adults. Metamorphosis is initiated by brain-derived prothoracicotropic hormone (PTTH), which stimulates the production of the molting hormone ecdysone via an incompletely defined signaling pathway. Here we demonstrate that Torso, a receptor tyrosine kinase that regulates embryonic terminal cell fate in Drosophila, is the PTTH receptor. Trunk, the embryonic Torso ligand, is related to PTTH, and ectopic expression of PTTH in the embryo partially rescues trunk mutants. In larvae, torso is expressed specifically in the prothoracic gland (PG), and its loss phenocopies the removal of PTTH. The activation of Torso by PTTH stimulates extracellular signal-regulated kinase (ERK) phosphorylation, and the loss of ERK in the PG phenocopies the loss of PTTH and Torso. We conclude that PTTH initiates metamorphosis by activation of the Torso/ERK pathway.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Rewitz, Kim F -- Yamanaka, Naoki -- Gilbert, Lawrence I -- O'Connor, Michael B -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2009 Dec 4;326(5958):1403-5. doi: 10.1126/science.1176450.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Genetics, Cell Biology, and Development, University of Minnesota, Minneapolis, MN 55455, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19965758" target="_blank"〉PubMed〈/a〉

    Description: The cytoskeleton, integrin-mediated adhesion, and substrate stiffness control a common set of cell functions required for development and homeostasis that are often deranged in cancer. The connection between these mechanical elements and chemical signaling processes is not known. Here, we show that alpha(5)beta(1) integrin switches between relaxed and tensioned states in response to myosin II-generated cytoskeletal force. Force combines with extracellular matrix stiffness to generate tension that triggers the integrin switch. This switch directly controls the alpha(5)beta(1)-fibronectin bond strength through engaging the synergy site in fibronectin and is required to generate signals through phosphorylation of focal adhesion kinase. In the context of tissues, this integrin switch connects cytoskeleton and extracellular matrix mechanics to adhesion-dependent motility and signaling pathways.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Friedland, Julie C -- Lee, Mark H -- Boettiger, David -- GM57388/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2009 Jan 30;323(5914):642-4. doi: 10.1126/science.1168441.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Institute for Medicine and Engineering, University of Pennsylvania, Philadelphia, PA 19104, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19179533" target="_blank"〉PubMed〈/a〉

    Description: Integrins are transmembrane cell-adhesion molecules that carry signals from the outside to the inside of the cell and vice versa. Like other cell surface receptors, integrins signal in response to ligand binding; however, events within the cell can also regulate the affinity of integrins for ligands. This feature is important in physiological situations such as those in blood, in which cells are always in close proximity to their ligands, yet cell-ligand interactions occur only after integrin activation in response to specific external cues. This review focuses on the mechanisms whereby two key proteins, talin and the kindlins, regulate integrin activation by binding the tails of integrin-beta subunits.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Moser, Markus -- Legate, Kyle R -- Zent, Roy -- Fassler, Reinhard -- DK 69921/DK/NIDDK NIH HHS/ -- DK075594/DK/NIDDK NIH HHS/ -- DK65138/DK/NIDDK NIH HHS/ -- New York, N.Y. -- Science. 2009 May 15;324(5929):895-9. doi: 10.1126/science.1163865.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Max Planck Institute of Biochemistry, 82152 Martinsried, Germany.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19443776" target="_blank"〉PubMed〈/a〉

    Description: Heterozygous mutations in the gene encoding isocitrate dehydrogenase-1 (IDH1) occur in certain human brain tumors, but their mechanistic role in tumor development is unknown. We have shown that tumor-derived IDH1 mutations impair the enzyme's affinity for its substrate and dominantly inhibit wild-type IDH1 activity through the formation of catalytically inactive heterodimers. Forced expression of mutant IDH1 in cultured cells reduces formation of the enzyme product, alpha-ketoglutarate (alpha-KG), and increases the levels of hypoxia-inducible factor subunit HIF-1alpha, a transcription factor that facilitates tumor growth when oxygen is low and whose stability is regulated by alpha-KG. The rise in HIF-1alpha levels was reversible by an alpha-KG derivative. HIF-1alpha levels were higher in human gliomas harboring an IDH1 mutation than in tumors without a mutation. Thus, IDH1 appears to function as a tumor suppressor that, when mutationally inactivated, contributes to tumorigenesis in part through induction of the HIF-1 pathway.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3251015/" 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/PMC3251015/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Zhao, Shimin -- Lin, Yan -- Xu, Wei -- Jiang, Wenqing -- Zha, Zhengyu -- Wang, Pu -- Yu, Wei -- Li, Zhiqiang -- Gong, Lingling -- Peng, Yingjie -- Ding, Jianping -- Lei, Qunying -- Guan, Kun-Liang -- Xiong, Yue -- R01 CA068377/CA/NCI NIH HHS/ -- R01 CA068377-14/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 2009 Apr 10;324(5924):261-5. doi: 10.1126/science.1170944.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Molecular and Cell Biology Laboratory, Institute of Biomedical Sciences, Fudan University, 130 Dong-An Road, Shanghai 200032, China.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19359588" target="_blank"〉PubMed〈/a〉

    Description: The toolbox of rat genetics currently lacks the ability to introduce site-directed, heritable mutations into the genome to create knockout animals. By using engineered zinc-finger nucleases (ZFNs) designed to target an integrated reporter and two endogenous rat genes, Immunoglobulin M (IgM) and Rab38, we demonstrate that a single injection of DNA or messenger RNA encoding ZFNs into the one-cell rat embryo leads to a high frequency of animals carrying 25 to 100% disruption at the target locus. These mutations are faithfully and efficiently transmitted through the germline. Our data demonstrate the feasibility of targeted gene disruption in multiple rat strains within 4 months time, paving the way to a humanized monoclonal antibody platform and additional human disease models.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2831805/" 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/PMC2831805/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Geurts, Aron M -- Cost, Gregory J -- Freyvert, Yevgeniy -- Zeitler, Bryan -- Miller, Jeffrey C -- Choi, Vivian M -- Jenkins, Shirin S -- Wood, Adam -- Cui, Xiaoxia -- Meng, Xiangdong -- Vincent, Anna -- Lam, Stephen -- Michalkiewicz, Mieczyslaw -- Schilling, Rebecca -- Foeckler, Jamie -- Kalloway, Shawn -- Weiler, Hartmut -- Menoret, Severine -- Anegon, Ignacio -- Davis, Gregory D -- Zhang, Lei -- Rebar, Edward J -- Gregory, Philip D -- Urnov, Fyodor D -- Jacob, Howard J -- Buelow, Roland -- 5P01HL082798-03/HL/NHLBI NIH HHS/ -- 5U01HL066579-08/HL/NHLBI NIH HHS/ -- P01 HL082798/HL/NHLBI NIH HHS/ -- P01 HL082798-03/HL/NHLBI NIH HHS/ -- U01 HL066579/HL/NHLBI NIH HHS/ -- U01 HL066579-08/HL/NHLBI NIH HHS/ -- New York, N.Y. -- Science. 2009 Jul 24;325(5939):433. doi: 10.1126/science.1172447.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Human and Molecular Genetics Center, Medical College of Wisconsin, Milwaukee, WI 52336, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19628861" target="_blank"〉PubMed〈/a〉

    Description: A current paradigm states that monocytes circulate freely and patrol blood vessels but differentiate irreversibly into dendritic cells (DCs) or macrophages upon tissue entry. Here we show that bona fide undifferentiated monocytes reside in the spleen and outnumber their equivalents in circulation. The reservoir monocytes assemble in clusters in the cords of the subcapsular red pulp and are distinct from macrophages and DCs. In response to ischemic myocardial injury, splenic monocytes increase their motility, exit the spleen en masse, accumulate in injured tissue, and participate in wound healing. These observations uncover a role for the spleen as a site for storage and rapid deployment of monocytes and identify splenic monocytes as a resource that the body exploits to regulate inflammation.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2803111/" 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/PMC2803111/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Swirski, Filip K -- Nahrendorf, Matthias -- Etzrodt, Martin -- Wildgruber, Moritz -- Cortez-Retamozo, Virna -- Panizzi, Peter -- Figueiredo, Jose-Luiz -- Kohler, Rainer H -- Chudnovskiy, Aleksey -- Waterman, Peter -- Aikawa, Elena -- Mempel, Thorsten R -- Libby, Peter -- Weissleder, Ralph -- Pittet, Mikael J -- 1R01HL095612/HL/NHLBI NIH HHS/ -- P01 A154904/PHS HHS/ -- P01 AI054904/AI/NIAID NIH HHS/ -- P01 AI054904-010001/AI/NIAID NIH HHS/ -- P50 CA086355/CA/NCI NIH HHS/ -- P50 CA086355-07/CA/NCI NIH HHS/ -- P50 CA86355/CA/NCI NIH HHS/ -- R00 HL094533/HL/NHLBI NIH HHS/ -- R01 HL095629/HL/NHLBI NIH HHS/ -- R01 HL096576/HL/NHLBI NIH HHS/ -- R24 CA69246/CA/NCI NIH HHS/ -- U01 HL080731/HL/NHLBI NIH HHS/ -- U01 HL080731-05/HL/NHLBI NIH HHS/ -- U54 CA126515/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 2009 Jul 31;325(5940):612-6. doi: 10.1126/science.1175202.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Center for Systems Biology, Massachusetts General Hospital and Harvard Medical School, Boston, MA 02114, USA. fswirski@mgh.harvard.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19644120" target="_blank"〉PubMed〈/a〉

    Description: Sex determination mechanisms differ among animal species, but it is not clear how these differences evolve. New sex determiners may arise in response to sexual conflicts, which occur when traits benefit one sex but hinder the other. We identified the genetic basis for the orange-blotch (OB) color pattern, a trait under sexually antagonistic selection in the cichlid fish of Lake Malawi, East Africa. The OB phenotype is due to a cis-regulatory mutation in the Pax7 gene. OB provides benefits of camouflage to females but disrupts the species-specific male color patterns used for mate recognition. We suggest that the resulting sexual conflict over the OB allele has been resolved by selection for a novel female sex determination locus that has invaded populations with an ancestral male sex determination system.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3174268/" 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/PMC3174268/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Roberts, Reade B -- Ser, Jennifer R -- Kocher, Thomas D -- F32HD051383/HD/NICHD NIH HHS/ -- R01 HD058635/HD/NICHD NIH HHS/ -- R01 HD058635-04/HD/NICHD NIH HHS/ -- R01HD058635/HD/NICHD NIH HHS/ -- New York, N.Y. -- Science. 2009 Nov 13;326(5955):998-1001. doi: 10.1126/science.1174705.

    Description: The imprints of domestication and breed development on the genomes of livestock likely differ from those of companion animals. A deep draft sequence assembly of shotgun reads from a single Hereford female and comparative sequences sampled from six additional breeds were used to develop probes to interrogate 37,470 single-nucleotide polymorphisms (SNPs) in 497 cattle from 19 geographically and biologically diverse breeds. These data show that cattle have undergone a rapid recent decrease in effective population size from a very large ancestral population, possibly due to bottlenecks associated with domestication, selection, and breed formation. Domestication and artificial selection appear to have left detectable signatures of selection within the cattle genome, yet the current levels of diversity within breeds are at least as great as exists within humans.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2735092/" 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/PMC2735092/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bovine HapMap Consortium -- Gibbs, Richard A -- Taylor, Jeremy F -- Van Tassell, Curtis P -- Barendse, William -- Eversole, Kellye A -- Gill, Clare A -- Green, Ronnie D -- Hamernik, Debora L -- Kappes, Steven M -- Lien, Sigbjorn -- Matukumalli, Lakshmi K -- McEwan, John C -- Nazareth, Lynne V -- Schnabel, Robert D -- Weinstock, George M -- Wheeler, David A -- Ajmone-Marsan, Paolo -- Boettcher, Paul J -- Caetano, Alexandre R -- Garcia, Jose Fernando -- Hanotte, Olivier -- Mariani, Paola -- Skow, Loren C -- Sonstegard, Tad S -- Williams, John L -- Diallo, Boubacar -- Hailemariam, Lemecha -- Martinez, Mario L -- Morris, Chris A -- Silva, Luiz O C -- Spelman, Richard J -- Mulatu, Woudyalew -- Zhao, Keyan -- Abbey, Colette A -- Agaba, Morris -- Araujo, Flabio R -- Bunch, Rowan J -- Burton, James -- Gorni, Chiara -- Olivier, Hanotte -- Harrison, Blair E -- Luff, Bill -- Machado, Marco A -- Mwakaya, Joel -- Plastow, Graham -- Sim, Warren -- Smith, Timothy -- Thomas, Merle B -- Valentini, Alessio -- Williams, Paul -- Womack, James -- Woolliams, John A -- Liu, Yue -- Qin, Xiang -- Worley, Kim C -- Gao, Chuan -- Jiang, Huaiyang -- Moore, Stephen S -- Ren, Yanru -- Song, Xing-Zhi -- Bustamante, Carlos D -- Hernandez, Ryan D -- Muzny, Donna M -- Patil, Shobha -- San Lucas, Anthony -- Fu, Qing -- Kent, Matthew P -- Vega, Richard -- Matukumalli, Aruna -- McWilliam, Sean -- Sclep, Gert -- Bryc, Katarzyna -- Choi, Jungwoo -- Gao, Hong -- Grefenstette, John J -- Murdoch, Brenda -- Stella, Alessandra -- Villa-Angulo, Rafael -- Wright, Mark -- Aerts, Jan -- Jann, Oliver -- Negrini, Riccardo -- Goddard, Mike E -- Hayes, Ben J -- Bradley, Daniel G -- Barbosa da Silva, Marcos -- Lau, Lilian P L -- Liu, George E -- Lynn, David J -- Panzitta, Francesca -- Dodds, Ken G -- R01 GM083606/GM/NIGMS NIH HHS/ -- R01 GM083606-02/GM/NIGMS NIH HHS/ -- U54 HG003273/HG/NHGRI NIH HHS/ -- New York, N.Y. -- Science. 2009 Apr 24;324(5926):528-32. doi: 10.1126/science.1167936.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19390050" target="_blank"〉PubMed〈/a〉

    Description: In the early stages of viral infection, outcomes depend on a race between expansion of infection and the immune response generated to contain it. We combined in situ tetramer staining with in situ hybridization to visualize, map, and quantify relationships between immune effector cells and their targets in tissues. In simian immunodeficiency virus infections in macaques and lymphocytic choriomeningitis virus infections in mice, the magnitude and timing of the establishment of an excess of effector cells versus targets were found to correlate with the extent of control and the infection outcome (i.e., control and clearance versus partial or poor control and persistent infection). This method highlights the importance of the location, timing, and magnitude of the immune response needed for a vaccine to be effective against agents of persistent infection, such as HIV-1.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2753492/" 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/PMC2753492/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Li, Qingsheng -- Skinner, Pamela J -- Ha, Sang-Jun -- Duan, Lijie -- Mattila, Teresa L -- Hage, Aaron -- White, Cara -- Barber, Daniel L -- O'Mara, Leigh -- Southern, Peter J -- Reilly, Cavan S -- Carlis, John V -- Miller, Christopher J -- Ahmed, Rafi -- Haase, Ashley T -- AI066314/AI/NIAID NIH HHS/ -- AI20048/AI/NIAID NIH HHS/ -- AI48484/AI/NIAID NIH HHS/ -- P01 AI066314/AI/NIAID NIH HHS/ -- P01 AI066314-010003/AI/NIAID NIH HHS/ -- P01 AI066314-020003/AI/NIAID NIH HHS/ -- P01 AI066314-030003/AI/NIAID NIH HHS/ -- P01 AI066314-040003/AI/NIAID NIH HHS/ -- P51 RR000169/RR/NCRR NIH HHS/ -- P51 RR000169-430198/RR/NCRR NIH HHS/ -- R01 AI048484/AI/NIAID NIH HHS/ -- R01 AI048484-01/AI/NIAID NIH HHS/ -- R01 AI048484-02/AI/NIAID NIH HHS/ -- R01 AI048484-03/AI/NIAID NIH HHS/ -- R01 AI048484-04/AI/NIAID NIH HHS/ -- RR00169/RR/NCRR NIH HHS/ -- New York, N.Y. -- Science. 2009 Mar 27;323(5922):1726-9. doi: 10.1126/science.1168676.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Microbiology, Medical School, University of Minnesota, Minneapolis, MN 55455, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19325114" target="_blank"〉PubMed〈/a〉

    Description: Two experiments revealed that (i) people can more accurately predict their affective reactions to a future event when they know how a neighbor in their social network reacted to the event than when they know about the event itself and (ii) people do not believe this. Undergraduates made more accurate predictions about their affective reactions to a 5-minute speed date (n = 25) and to a peer evaluation (n = 88) when they knew only how another undergraduate had reacted to these events than when they had information about the events themselves. Both participants and independent judges mistakenly believed that predictions based on information about the event would be more accurate than predictions based on information about how another person had reacted to it.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gilbert, Daniel T -- Killingsworth, Matthew A -- Eyre, Rebecca N -- Wilson, Timothy D -- New York, N.Y. -- Science. 2009 Mar 20;323(5921):1617-9. doi: 10.1126/science.1166632.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Psychology, Harvard University, Cambridge, MA 02138, USA. gilbert@wjh.harvard.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19299622" target="_blank"〉PubMed〈/a〉

    Description: Sleep is universal, strictly regulated, and necessary for cognition. Why this is so remains a mystery, although recent work suggests that sleep, memory, and plasticity are linked. However, little is known about how wakefulness and sleep affect synapses. Using Western blots and confocal microscopy in Drosophila, we found that protein levels of key components of central synapses were high after waking and low after sleep. These changes were related to behavioral state rather than time of day and occurred in all major areas of the Drosophila brain. The decrease of synaptic markers during sleep was progressive, and sleep was necessary for their decline. Thus, sleep may be involved in maintaining synaptic homeostasis altered by waking activities.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2715914/" 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/PMC2715914/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gilestro, Giorgio F -- Tononi, Giulio -- Cirelli, Chiara -- DP1 OD000579/OD/NIH HHS/ -- DP1 OD000579-01/OD/NIH HHS/ -- DP1 OD000579-02/OD/NIH HHS/ -- DP1 OD000579-03/OD/NIH HHS/ -- DP1 OD000579-04/OD/NIH HHS/ -- R01 GM075315/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2009 Apr 3;324(5923):109-12. doi: 10.1126/science.1166673.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Psychiatry, University of Wisconsin, Madison, WI 53719, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19342593" target="_blank"〉PubMed〈/a〉

    Description: To intercept invading microbes that threaten growth and reproduction, plants evolved a sophisticated innate immune system. Recognition of specialized pathogens is mediated by resistance proteins that function as molecular switches. Pathogen perception by these multidomain proteins seems to trigger a series of conformational changes dependent on nucleotide exchange. The activated resistance protein switches on host defenses, often culminating in the death of infected cells. Given their control over life and death, activity of these proteins requires tight regulation that involves intramolecular interactions between the various domains.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Takken, F L W -- Tameling, W I L -- New York, N.Y. -- Science. 2009 May 8;324(5928):744-6. doi: 10.1126/science.1171666.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Plant Pathology, Swammerdam Institute for Life Sciences (SILS), University of Amsterdam, Post Office Box 94215, 1090 GE Amsterdam, the Netherlands.
