    Description: Coat color and type are essential characteristics of domestic dog breeds. Although the genetic basis of coat color has been well characterized, relatively little is known about the genes influencing coat growth pattern, length, and curl. We performed genome-wide association studies of more than 1000 dogs from 80 domestic breeds to identify genes associated with canine fur phenotypes. Taking advantage of both inter- and intrabreed variability, we identified distinct mutations in three genes, RSPO2, FGF5, and KRT71 (encoding R-spondin-2, fibroblast growth factor-5, and keratin-71, respectively), that together account for most coat phenotypes in purebred dogs in the United States. Thus, an array of varied and seemingly complex phenotypes can be reduced to the combinatorial effects of only a few genes.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2897713/" 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/PMC2897713/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Cadieu, Edouard -- Neff, Mark W -- Quignon, Pascale -- Walsh, Kari -- Chase, Kevin -- Parker, Heidi G -- Vonholdt, Bridgett M -- Rhue, Alison -- Boyko, Adam -- Byers, Alexandra -- Wong, Aaron -- Mosher, Dana S -- Elkahloun, Abdel G -- Spady, Tyrone C -- Andre, Catherine -- Lark, K Gordon -- Cargill, Michelle -- Bustamante, Carlos D -- Wayne, Robert K -- Ostrander, Elaine A -- 1R01GM83606/GM/NIGMS NIH HHS/ -- GM063056/GM/NIGMS NIH HHS/ -- R01 GM063056/GM/NIGMS NIH HHS/ -- R01 GM063056-09/GM/NIGMS NIH HHS/ -- Intramural NIH HHS/ -- New York, N.Y. -- Science. 2009 Oct 2;326(5949):150-3. doi: 10.1126/science.1177808.

    Description: RNA interference (RNAi), a gene-silencing pathway triggered by double-stranded RNA, is conserved in diverse eukaryotic species but has been lost in the model budding yeast Saccharomyces cerevisiae. Here, we show that RNAi is present in other budding yeast species, including Saccharomyces castellii and Candida albicans. These species use noncanonical Dicer proteins to generate small interfering RNAs, which mostly correspond to transposable elements and Y' subtelomeric repeats. In S. castellii, RNAi mutants are viable but have excess Y' messenger RNA levels. In S. cerevisiae, introducing Dicer and Argonaute of S. castellii restores RNAi, and the reconstituted pathway silences endogenous retrotransposons. These results identify a previously unknown class of Dicer proteins, bring the tool of RNAi to the study of budding yeasts, and bring the tools of budding yeast to the study of RNAi.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3786161/" 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/PMC3786161/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Drinnenberg, Ines A -- Weinberg, David E -- Xie, Kathleen T -- Mower, Jeffrey P -- Wolfe, Kenneth H -- Fink, Gerald R -- Bartel, David P -- GM0305010/GM/NIGMS NIH HHS/ -- GM040266/GM/NIGMS NIH HHS/ -- GM067031/GM/NIGMS NIH HHS/ -- R01 GM067031/GM/NIGMS NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2009 Oct 23;326(5952):544-50. doi: 10.1126/science.1176945.

    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: Prabhakar et al. (Reports, 5 September 2008, p. 1346) argued that the conserved noncoding sequence HACNS1 has undergone positive selection and contributed to human adaptation. However, the pattern of substitution in HACNS1 is more consistent with the neutral process of biased gene conversion (BGC). The reported human-specific gain of function is likely due to the accumulation of deleterious mutations driven by BGC, not positive selection.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Duret, Laurent -- Galtier, Nicolas -- New York, N.Y. -- Science. 2009 Feb 6;323(5915):714; author reply 714. doi: 10.1126/science.1165848.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Universite de Lyon, Universite Lyon 1, CNRS, UMR5558, Laboratoire de Biometrie et Biologie Evolutive, F-69622, Villeurbanne, France. duret@biomserv.univ-lyon1.fr〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19197042" target="_blank"〉PubMed〈/a〉

    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: Simocyclinones are bifunctional antibiotics that inhibit bacterial DNA gyrase by preventing DNA binding to the enzyme. We report the crystal structure of the complex formed between the N-terminal domain of the Escherichia coli gyrase A subunit and simocyclinone D8, revealing two binding pockets that separately accommodate the aminocoumarin and polyketide moieties of the antibiotic. These are close to, but distinct from, the quinolone-binding site, consistent with our observations that several mutations in this region confer resistance to both agents. Biochemical studies show that the individual moieties of simocyclinone D8 are comparatively weak inhibitors of gyrase relative to the parent compound, but their combination generates a more potent inhibitor.

    Description: Biodiversity hotspots, representing regions with high species endemism and conservation threat, have been mapped globally. Yet, biodiversity distribution data from within hotspots are too sparse for effective conservation in the face of rapid environmental change. Using frogs as indicators, ecological niche models under paleoclimates, and simultaneous Bayesian analyses of multispecies molecular data, we compare alternative hypotheses of assemblage-scale response to late Quaternary climate change. This reveals a hotspot within the Brazilian Atlantic forest hotspot. We show that the southern Atlantic forest was climatically unstable relative to the central region, which served as a large climatic refugium for neotropical species in the late Pleistocene. This sets new priorities for conservation in Brazil and establishes a validated approach to biodiversity prediction in other understudied, species-rich regions.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Carnaval, Ana Carolina -- Hickerson, Michael J -- Haddad, Celio F B -- Rodrigues, Miguel T -- Moritz, Craig -- New York, N.Y. -- Science. 2009 Feb 6;323(5915):785-9. doi: 10.1126/science.1166955.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Museum of Vertebrate Zoology, University of California, Berkeley, CA 94720-3160, USA. carnaval@berkeley.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19197066" target="_blank"〉PubMed〈/a〉

    Description: Rapid antigenic evolution in the influenza A virus hemagglutinin precludes effective vaccination with existing vaccines. To understand this phenomenon, we passaged virus in mice immunized with influenza vaccine. Neutralizing antibodies selected mutants with single-amino acid hemagglutinin substitutions that increased virus binding to cell surface glycan receptors. Passaging these high-avidity binding mutants in naive mice, but not immune mice, selected for additional hemagglutinin substitutions that decreased cellular receptor binding avidity. Analyzing a panel of monoclonal antibody hemagglutinin escape mutants revealed a positive correlation between receptor binding avidity and escape from polyclonal antibodies. We propose that in response to variation in neutralizing antibody pressure between individuals, influenza A virus evolves by adjusting receptor binding avidity via amino acid substitutions throughout the hemagglutinin globular domain, many of which simultaneously alter antigenicity.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2784927/" 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/PMC2784927/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hensley, Scott E -- Das, Suman R -- Bailey, Adam L -- Schmidt, Loren M -- Hickman, Heather D -- Jayaraman, Akila -- Viswanathan, Karthik -- Raman, Rahul -- Sasisekharan, Ram -- Bennink, Jack R -- Yewdell, Jonathan W -- GM 57073/GM/NIGMS NIH HHS/ -- U54 GM62116/GM/NIGMS NIH HHS/ -- Z01 AI001014-01/Intramural NIH HHS/ -- New York, N.Y. -- Science. 2009 Oct 30;326(5953):734-6. doi: 10.1126/science.1178258.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratory of Viral Diseases, National Institute of Allergy and Infectious Diseases, Bethesda, MD 20892, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19900932" 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: 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: Rotavirus outer-layer protein VP7 is a principal target of protective antibodies. Removal of free calcium ions (Ca2+) dissociates VP7 trimers into monomers, releasing VP7 from the virion, and initiates penetration-inducing conformational changes in the other outer-layer protein, VP4. We report the crystal structure at 3.4 angstrom resolution of VP7 bound with the Fab fragment of a neutralizing monoclonal antibody. The Fab binds across the outer surface of the intersubunit contact, which contains two Ca2+ sites. Mutations that escape neutralization by other antibodies suggest that the same region bears the epitopes of most neutralizing antibodies. The monovalent Fab is sufficient to neutralize infectivity. We propose that neutralizing antibodies against VP7 act by stabilizing the trimer, thereby inhibiting the uncoating trigger for VP4 rearrangement. A disulfide-linked trimer is a potential subunit immunogen.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2995306/" 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/PMC2995306/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Aoki, Scott T -- Settembre, Ethan C -- Trask, Shane D -- Greenberg, Harry B -- Harrison, Stephen C -- Dormitzer, Philip R -- AI-21362/AI/NIAID NIH HHS/ -- CA-13202/CA/NCI NIH HHS/ -- DK-56339/DK/NIDDK NIH HHS/ -- R37 CA013202/CA/NCI NIH HHS/ -- R37 CA013202-38/CA/NCI NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2009 Jun 12;324(5933):1444-7. doi: 10.1126/science.1170481.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratory of Molecular Medicine, Children's Hospital, Boston, MA 02115, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19520960" 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. These findings revise widely accepted limits of acoustic behavior in mosquitoes.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2847473/" 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/PMC2847473/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Cator, Lauren J -- Arthur, Ben J -- Harrington, Laura C -- Hoy, Ronald R -- R01 DC000103/DC/NIDCD NIH HHS/ -- R01 DC000103-34/DC/NIDCD NIH HHS/ -- New York, N.Y. -- Science. 2009 Feb 20;323(5917):1077-9. doi: 10.1126/science.1166541.

    Description: Genes are not simply turned on or off, but instead their expression is fine-tuned to meet the needs of a cell. How genes are modulated so precisely is not well understood. The glucocorticoid receptor (GR) regulates target genes by associating with specific DNA binding sites, the sequences of which differ between genes. Traditionally, these binding sites have been viewed only as docking sites. Using structural, biochemical, and cell-based assays, we show that GR binding sequences, differing by as little as a single base pair, differentially affect GR conformation and regulatory activity. We therefore propose that DNA is a sequence-specific allosteric ligand of GR that tailors the activity of the receptor toward specific target genes.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2777810/" 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/PMC2777810/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Meijsing, Sebastiaan H -- Pufall, Miles A -- So, Alex Y -- Bates, Darren L -- Chen, Lin -- Yamamoto, Keith R -- GM08537/GM/NIGMS NIH HHS/ -- R01 CA020535/CA/NCI NIH HHS/ -- R01 CA020535-31/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 2009 Apr 17;324(5925):407-10. doi: 10.1126/science.1164265.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Cellular and Molecular Pharmacology, University of California, San Francisco, CA 94158, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19372434" target="_blank"〉PubMed〈/a〉

    Description: Synonymous mutations do not alter the encoded protein, but they can influence gene expression. To investigate how, we engineered a synthetic library of 154 genes that varied randomly at synonymous sites, but all encoded the same green fluorescent protein (GFP). When expressed in Escherichia coli, GFP protein levels varied 250-fold across the library. GFP messenger RNA (mRNA) levels, mRNA degradation patterns, and bacterial growth rates also varied, but codon bias did not correlate with gene expression. Rather, the stability of mRNA folding near the ribosomal binding site explained more than half the variation in protein levels. In our analysis, mRNA folding and associated rates of translation initiation play a predominant role in shaping expression levels of individual genes, whereas codon bias influences global translation efficiency and cellular fitness.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3902468/" 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/PMC3902468/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kudla, Grzegorz -- Murray, Andrew W -- Tollervey, David -- Plotkin, Joshua B -- BB/D019621/1/Biotechnology and Biological Sciences Research Council/United Kingdom -- BB/DO19621/1/Biotechnology and Biological Sciences Research Council/United Kingdom -- BB/DO19621/1/Wellcome Trust/United Kingdom -- P50 GM068763/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2009 Apr 10;324(5924):255-8. doi: 10.1126/science.1170160.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biology and Program in Applied Mathematics and Computational Science, University of Pennsylvania, Philadelphia, PA 19104, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19359587" 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: Oxygen deprivation is rapidly deleterious for most organisms. However, Caenorhabditis elegans has developed the ability to survive anoxia for at least 48 hours. Mutations in the DAF-2/DAF-16 insulin-like signaling pathway promote such survival. We describe a pathway involving the HYL-2 ceramide synthase that acts independently of DAF-2. Loss of the ceramide synthase gene hyl-2 results in increased sensitivity of C. elegans to anoxia. C. elegans has two ceramide synthases, hyl-1 and hyl-2, that participate in ceramide biogenesis and affect its ability to survive anoxic conditions. In contrast to hyl-2(lf) mutants, hyl-1(lf) mutants are more resistant to anoxia than normal animals. HYL-1 and HYL-2 have complementary specificities for fatty acyl chains. These data indicate that specific ceramides produced by HYL-2 confer resistance to anoxia.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Menuz, Vincent -- Howell, Kate S -- Gentina, Sebastien -- Epstein, Sharon -- Riezman, Isabelle -- Fornallaz-Mulhauser, Monique -- Hengartner, Michael O -- Gomez, Marie -- Riezman, Howard -- Martinou, Jean-Claude -- New York, N.Y. -- Science. 2009 Apr 17;324(5925):381-4. doi: 10.1126/science.1168532.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Cell Biology, University of Geneva, CH-1211 Geneva 4, Switzerland.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19372430" target="_blank"〉PubMed〈/a〉

    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: The YODA (YDA) mitogen-activated protein kinase pathway promotes elongation of the Arabidopsis zygote and development of its basal daughter cell into the extra-embryonic suspensor. Here, we show that the interleukin-1 receptor-associated kinase (IRAK)/Pelle-like kinase gene SHORT SUSPENSOR (SSP) regulates this pathway through a previously unknown parent-of-origin effect. SSP transcripts are produced in mature pollen but do not appear to be translated. Instead, they are delivered via the sperm cells to the zygote and the endosperm, where SSP protein transiently accumulates. Ectopic expression of SSP protein in the leaf epidermis is sufficient to activate YDA-dependent signaling. We propose that SSP protein produced from paternal transcripts upon fertilization triggers zygotic YDA activity, providing an essential temporal cue for the regulation of the asymmetric first division.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bayer, Martin -- Nawy, Tal -- Giglione, Carmela -- Galli, Mary -- Meinnel, Thierry -- Lukowitz, Wolfgang -- New York, N.Y. -- Science. 2009 Mar 13;323(5920):1485-8. doi: 10.1126/science.1167784.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Cold Spring Harbor Laboratory, Cold Spring Harbor, NY 11724, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19286558" target="_blank"〉PubMed〈/a〉

    Description: Histone deacetylase 4 (HDAC4) shuttles between the nucleus and cytoplasm and serves as a nuclear co-repressor that regulates bone and muscle development. We report that HDAC4 regulates the survival of retinal neurons in the mouse in normal and pathological conditions. Reduction in HDAC4 expression during normal retinal development led to apoptosis of rod photoreceptors and bipolar (BP) interneurons, whereas overexpression reduced naturally occurring cell death of the BP cells. HDAC4 overexpression in a mouse model of retinal degeneration prolonged photoreceptor survival. The survival effect was due to the activity of HDAC4 in the cytoplasm and relied at least partly on the activity of hypoxia-inducible factor 1alpha (HIF1alpha). These data provide evidence that HDAC4 plays an important role in promoting the survival of retinal neurons.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3339762/" 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/PMC3339762/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Chen, Bo -- Cepko, Constance L -- EYO 14466/PHS HHS/ -- R01 EY014466/EY/NEI NIH HHS/ -- R01 EY014466-05/EY/NEI NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2009 Jan 9;323(5911):256-9. doi: 10.1126/science.1166226.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Genetics and Howard Hughes Medical Institute, Harvard Medical School, 77 Avenue Louis Pasteur, Boston, MA 02115, USA. bochen@genetics.med.harvard.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19131628" target="_blank"〉PubMed〈/a〉

    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). Preventing nitrosylation of Drp1 by cysteine mutation abrogated these neurotoxic events. SNO-Drp1 is increased in brains of human Alzheimer's disease patients and may thus contribute to the pathogenesis of neurodegeneration.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2823371/" 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/PMC2823371/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Cho, Dong-Hyung -- Nakamura, Tomohiro -- Fang, Jianguo -- Cieplak, Piotr -- Godzik, Adam -- Gu, Zezong -- Lipton, Stuart A -- P01 ES016738/ES/NIEHS NIH HHS/ -- P01 ES016738-01/ES/NIEHS NIH HHS/ -- P01 ES016738-010003/ES/NIEHS NIH HHS/ -- P01 ES016738-02/ES/NIEHS NIH HHS/ -- P01 ES016738-020003/ES/NIEHS NIH HHS/ -- P01 HD029587/HD/NICHD NIH HHS/ -- P01 HD029587-16/HD/NICHD NIH HHS/ -- P01 HD29587/HD/NICHD NIH HHS/ -- P30 NS057096/NS/NINDS NIH HHS/ -- P30 NS057096-04/NS/NINDS NIH HHS/ -- R01 EY005477/EY/NEI NIH HHS/ -- R01 EY005477-25/EY/NEI NIH HHS/ -- R01 EY05477/EY/NEI NIH HHS/ -- New York, N.Y. -- Science. 2009 Apr 3;324(5923):102-5. doi: 10.1126/science.1171091.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Center for Neuroscience, Aging, and Stem Cell Research, Burnham Institute for Medical Research, 10901 North Torrey Pines Road, La Jolla, CA 92037, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19342591" 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: 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 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: The nematode Caenorhabditis elegans responds to pathogenic bacteria with conserved innate immune responses and pathogen avoidance behaviors. We investigated natural variation in C. elegans resistance to pathogen infection. With the use of quantitative genetic analysis, we determined that the pathogen susceptibility difference between the laboratory wild-type strain N2 and the wild isolate CB4856 is caused by a polymorphism in the npr-1 gene, which encodes a homolog of the mammalian neuropeptide Y receptor. We show that the mechanism of NPR-1-mediated pathogen resistance is through oxygen-dependent behavioral avoidance rather than direct regulation of innate immunity.

    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: 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: 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: 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: The LKB1 tumor suppressor is a protein kinase that controls the activity of adenosine monophosphate-activated protein kinase (AMPK). LKB1 activity is regulated by the pseudokinase STRADalpha and the scaffolding protein MO25alpha through an unknown, phosphorylation-independent, mechanism. We describe the structure of the core heterotrimeric LKB1-STRADalpha-MO25alpha complex, revealing an unusual allosteric mechanism of LKB1 activation. STRADalpha adopts a closed conformation typical of active protein kinases and binds LKB1 as a pseudosubstrate. STRADalpha and MO25alpha promote the active conformation of LKB1, which is stabilized by MO25alpha interacting with the LKB1 activation loop. This previously undescribed mechanism of kinase activation may be relevant to understanding the evolution of other pseudokinases. The structure also reveals how mutations found in Peutz-Jeghers syndrome and in various sporadic cancers impair LKB1 function.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3518268/" 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/PMC3518268/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Zeqiraj, Elton -- Filippi, Beatrice Maria -- Deak, Maria -- Alessi, Dario R -- van Aalten, Daan M F -- 087590/Wellcome Trust/United Kingdom -- C33794/A10969/Cancer Research UK/United Kingdom -- G0900138/Medical Research Council/United Kingdom -- MC_U127070193/Medical Research Council/United Kingdom -- Wellcome Trust/United Kingdom -- New York, N.Y. -- Science. 2009 Dec 18;326(5960):1707-11. doi: 10.1126/science.1178377.

    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: 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. These data add to our understanding of the domestication processes and may have applications in devising pest control strategies and advancing the use of silkworms as efficient bioreactors.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3951477/" 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/PMC3951477/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Xia, Qingyou -- Guo, Yiran -- Zhang, Ze -- Li, Dong -- Xuan, Zhaoling -- Li, Zhuo -- Dai, Fangyin -- Li, Yingrui -- Cheng, Daojun -- Li, Ruiqiang -- Cheng, Tingcai -- Jiang, Tao -- Becquet, Celine -- Xu, Xun -- Liu, Chun -- Zha, Xingfu -- Fan, Wei -- Lin, Ying -- Shen, Yihong -- Jiang, Lan -- Jensen, Jeffrey -- Hellmann, Ines -- Tang, Si -- Zhao, Ping -- Xu, Hanfu -- Yu, Chang -- Zhang, Guojie -- Li, Jun -- Cao, Jianjun -- Liu, Shiping -- He, Ningjia -- Zhou, Yan -- Liu, Hui -- Zhao, Jing -- Ye, Chen -- Du, Zhouhe -- Pan, Guoqing -- Zhao, Aichun -- Shao, Haojing -- Zeng, Wei -- Wu, Ping -- Li, Chunfeng -- Pan, Minhui -- Li, Jingjing -- Yin, Xuyang -- Li, Dawei -- Wang, Juan -- Zheng, Huisong -- Wang, Wen -- Zhang, Xiuqing -- Li, Songgang -- Yang, Huanming -- Lu, Cheng -- Nielsen, Rasmus -- Zhou, Zeyang -- Wang, Jian -- Xiang, Zhonghuai -- Wang, Jun -- R01 HG003229/HG/NHGRI NIH HHS/ -- R01 HG003229-05/HG/NHGRI NIH HHS/ -- New York, N.Y. -- Science. 2009 Oct 16;326(5951):433-6. doi: 10.1126/science.1176620.

    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: Mammals have single-rowed dentitions, whereas many nonmammalian vertebrates have teeth in multiple rows. Neither the molecular mechanism regulating iterative tooth initiation nor that restricting mammalian tooth development in one row is known. We found that mice lacking the transcription factor odd-skipped related-2 (Osr2) develop supernumerary teeth lingual to their molars because of expansion of the odontogenic field. Osr2 was expressed in a lingual-to-buccal gradient and restricted expression of bone morphogenetic protein 4 (Bmp4), an essential odontogenic signal, in the developing tooth mesenchyme. Expansion of odontogenic field in Osr2-deficient mice required Msx1, a feedback activator of Bmp4 expression. These findings suggest that the Bmp4-Msx1 pathway propagates mesenchymal activation for sequential tooth induction and that spatial modulation of this pathway provides a mechanism for patterning vertebrate dentition.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2650836/" 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/PMC2650836/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Zhang, Zunyi -- Lan, Yu -- Chai, Yang -- Jiang, Rulang -- R01 DE013681/DE/NIDCR NIH HHS/ -- R01 DE013681-06/DE/NIDCR NIH HHS/ -- R01 DE013681-07/DE/NIDCR NIH HHS/ -- R01 DE013681-08/DE/NIDCR NIH HHS/ -- R01 DE013681-09/DE/NIDCR NIH HHS/ -- R01DE013681/DE/NIDCR NIH HHS/ -- T32DE007202/DE/NIDCR NIH HHS/ -- New York, N.Y. -- Science. 2009 Feb 27;323(5918):1232-4. doi: 10.1126/science.1167418.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Center for Oral Biology and Department of Biomedical Genetics, University of Rochester Medical Center, Rochester, NY 14642, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19251632" 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: Temperature affects the physiology, behavior, and evolution of organisms. We conducted mutagenesis and screens for mutants with altered temperature preference in Drosophila melanogaster and identified a cryophilic (cold-seeking) mutant, named atsugari (atu). Reduced expression of the Drosophila ortholog of dystroglycan (DmDG) induced tolerance to cold as well as preference for the low temperature. A sustained increase in mitochondrial oxidative metabolism caused by the reduced expression of DmDG accounted for the cryophilic phenotype of the atu mutant. Although most ectothermic animals do not use metabolically produced heat to regulate body temperature, our results indicate that their thermoregulatory behavior is closely linked to rates of mitochondrial oxidative metabolism and that a mutation in a single gene can induce a sustained change in energy homeostasis and the thermal responses.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Takeuchi, Ken-Ichi -- Nakano, Yoshiro -- Kato, Utako -- Kaneda, Mizuho -- Aizu, Masako -- Awano, Wakae -- Yonemura, Shigenobu -- Kiyonaka, Shigeki -- Mori, Yasuo -- Yamamoto, Daisuke -- Umeda, Masato -- New York, N.Y. -- Science. 2009 Mar 27;323(5922):1740-3. doi: 10.1126/science.1165712.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Institute for Chemical Research, Kyoto University, Uji, Kyoto 611-0011, Japan.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19325118" 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: Knowing when and where a given protein is activated within intact animals assists in elucidating its in vivo function. With the use of a genetically encoded A-probe (activation bioprobe), we revealed that Cdc42 guanosine triphosphatase (GTPase) remains inactive within Drosophila embryos during the first two-thirds of embryogenesis. Within the central nervous system where Cdc42 activity first becomes up-regulated, individual neurons display patterns restricted to specific subcellular compartments. At both organismal and cellular levels, Cdc42's endogenous activation patterns in the wild type allow predictions of where loss-of-function phenotypes will emerge in cdc42/cdc42 mutants. Genetic tests support the importance of suppressing endogenous Cdc42 activities until needed. Thus, bioprobe-assisted analysis uncovers how ubiquitously expressed signaling proteins control cellular events through continual regulation of their activities within animals.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2729367/" 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/PMC2729367/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kamiyama, Daichi -- Chiba, Akira -- R01 MH068650-01A2/MH/NIMH NIH HHS/ -- R01 MH079432-01A1/MH/NIMH NIH HHS/ -- New York, N.Y. -- Science. 2009 Jun 5;324(5932):1338-40. doi: 10.1126/science.1170615.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biology and Miami Institute of Molecular Imaging and Computation, University of Miami, Coral Gables, FL 33146, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19498173" target="_blank"〉PubMed〈/a〉

    Description: The "royal disease," a blood disorder transmitted from Queen Victoria to European royal families, is a striking example of X-linked recessive inheritance. Although the disease is widely recognized to be a form of the blood clotting disorder hemophilia, its molecular basis has never been identified, and the royal disease is now likely extinct. We identified the likely disease-causing mutation by applying genomic methodologies (multiplex target amplification and massively parallel sequencing) to historical specimens from the Romanov branch of the royal family. The mutation occurs in F9, a gene on the X chromosome that encodes blood coagulation factor IX, and is predicted to alter RNA splicing and to lead to production of a truncated form of factor IX. Thus, the royal disease is the severe form of hemophilia, also known as hemophilia B or Christmas disease.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Rogaev, Evgeny I -- Grigorenko, Anastasia P -- Faskhutdinova, Gulnaz -- Kittler, Ellen L W -- Moliaka, Yuri K -- New York, N.Y. -- Science. 2009 Nov 6;326(5954):817. doi: 10.1126/science.1180660.

    Description: John Nash showed that within a complex system, individuals are best off if they make the best decision that they can, taking into account the decisions of the other individuals. Here, we investigate whether similar principles influence the evolution of signaling networks in multicellular animals. Specifically, by analyzing a set of metazoan species we observed a striking negative correlation of genomically encoded tyrosine content with biological complexity (as measured by the number of cell types in each organism). We discuss how this observed tyrosine loss correlates with the expansion of tyrosine kinases in the evolution of the metazoan lineage and how it may relate to the optimization of signaling systems in multicellular animals. We propose that this phenomenon illustrates genome-wide adaptive evolution to accommodate beneficial genetic perturbation.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3066034/" 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/PMC3066034/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Tan, Chris Soon Heng -- Pasculescu, Adrian -- Lim, Wendell A -- Pawson, Tony -- Bader, Gary D -- Linding, Rune -- R01 GM055040/GM/NIGMS NIH HHS/ -- R01 GM055040-11/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2009 Sep 25;325(5948):1686-8. doi: 10.1126/science.1174301.

    Description: Amyloid-beta (Abeta) accumulation in the brain extracellular space is a hallmark of Alzheimer's disease. The factors regulating this process are only partly understood. Abeta aggregation is a concentration-dependent process that is likely responsive to changes in brain interstitial fluid (ISF) levels of Abeta. Using in vivo microdialysis in mice, we found that the amount of ISF Abeta correlated with wakefulness. The amount of ISF Abeta also significantly increased during acute sleep deprivation and during orexin infusion, but decreased with infusion of a dual orexin receptor antagonist. Chronic sleep restriction significantly increased, and a dual orexin receptor antagonist decreased, Abeta plaque formation in amyloid precursor protein transgenic mice. Thus, the sleep-wake cycle and orexin may play a role in the pathogenesis of Alzheimer's disease.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2789838/" 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/PMC2789838/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kang, Jae-Eun -- Lim, Miranda M -- Bateman, Randall J -- Lee, James J -- Smyth, Liam P -- Cirrito, John R -- Fujiki, Nobuhiro -- Nishino, Seiji -- Holtzman, David M -- AG025824/AG/NIA NIH HHS/ -- AG029524/AG/NIA NIH HHS/ -- AG030946/AG/NIA NIH HHS/ -- K01 AG029524/AG/NIA NIH HHS/ -- K01 AG029524-03/AG/NIA NIH HHS/ -- K23 AG030946/AG/NIA NIH HHS/ -- K23 AG030946-03/AG/NIA NIH HHS/ -- MH072525/MH/NIMH NIH HHS/ -- NS065667/NS/NINDS NIH HHS/ -- P30 DK056341/DK/NIDDK NIH HHS/ -- P30 DK056341-09/DK/NIDDK NIH HHS/ -- P30 NS057105/NS/NINDS NIH HHS/ -- P30 NS057105-04/NS/NINDS NIH HHS/ -- P50 AG005681/AG/NIA NIH HHS/ -- R01 AG025824/AG/NIA NIH HHS/ -- R01 AG025824-03/AG/NIA NIH HHS/ -- R01 MH072525/MH/NIMH NIH HHS/ -- R01 MH072525-04/MH/NIMH NIH HHS/ -- R01 NS065667/NS/NINDS NIH HHS/ -- R01 NS065667-02/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 2009 Nov 13;326(5955):1005-7. doi: 10.1126/science.1180962.

    Description: Speciation often involves the evolution of incompatible gene interactions that cause sterility or lethality in hybrids between populations. These so-called hybrid incompatibilities occur between two or more functionally divergent loci. We show that the nucleoporin 160kDa (Nup160) gene of the fruitfly Drosophila simulans is incompatible with one or more factors on the D. melanogaster X chromosome, causing hybrid lethality. Nup160 encodes a nuclear pore complex protein and shows evidence of adaptive evolution. Furthermore, the protein encoded by Nup160 directly interacts with that of another hybrid lethality gene, Nup96, indicating that at least two lethal hybrid incompatibility genes have evolved as byproducts of divergent coevolution among interacting components of the Drosophila nuclear pore complex.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2826207/" 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/PMC2826207/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Tang, Shanwu -- Presgraves, Daven C -- R01 GM079543/GM/NIGMS NIH HHS/ -- R01 GM079543-01A1/GM/NIGMS NIH HHS/ -- R01-GM079543/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2009 Feb 6;323(5915):779-82. doi: 10.1126/science.1169123.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biology, University of Rochester, Rochester, NY 14627, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19197064" target="_blank"〉PubMed〈/a〉

    Description: Membrane fusion between vesicles and target membranes involves the zippering of a four-helix bundle generated by constituent helices derived from target- and vesicle-soluble N-ethylmaleimide-sensitive factor attachment protein receptors (SNAREs). In neurons, the protein complexin clamps otherwise spontaneous fusion by SNARE proteins, allowing neurotransmitters and other mediators to be secreted when and where they are needed as this clamp is released. The membrane-proximal accessory helix of complexin is necessary for clamping, but its mechanism of action is unknown. Here, we present experiments using a reconstituted fusion system that suggest a simple model in which the complexin accessory helix forms an alternative four-helix bundle with the target-SNARE near the membrane, preventing the vesicle-SNARE from completing its zippering.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3736854/" 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/PMC3736854/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Giraudo, Claudio G -- Garcia-Diaz, Alejandro -- Eng, William S -- Chen, Yuhang -- Hendrickson, Wayne A -- Melia, Thomas J -- Rothman, James E -- R01 GM071458/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2009 Jan 23;323(5913):512-6. doi: 10.1126/science.1166500.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Physiology and Cellular Biophysics, Columbia University, College of Physicians and Surgeons, 1150 Saint Nicholas Avenue, Russ Berrie Building, Room 520, New York, NY 10032, USA. claudio.giraudo@yale.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19164750" target="_blank"〉PubMed〈/a〉

    Description: Caloric restriction (CR), without malnutrition, delays aging and extends life span in diverse species; however, its effect on resistance to illness and mortality in primates has not been clearly established. We report findings of a 20-year longitudinal adult-onset CR study in rhesus monkeys aimed at filling this critical gap in aging research. In a population of rhesus macaques maintained at the Wisconsin National Primate Research Center, moderate CR lowered the incidence of aging-related deaths. At the time point reported, 50% of control fed animals survived as compared with 80% of the CR animals. Furthermore, CR delayed the onset of age-associated pathologies. Specifically, CR reduced the incidence of diabetes, cancer, cardiovascular disease, and brain atrophy. These data demonstrate that CR slows aging in a primate species.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2812811/" 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/PMC2812811/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Colman, Ricki J -- Anderson, Rozalyn M -- Johnson, Sterling C -- Kastman, Erik K -- Kosmatka, Kristopher J -- Beasley, T Mark -- Allison, David B -- Cruzen, Christina -- Simmons, Heather A -- Kemnitz, Joseph W -- Weindruch, Richard -- P01 AG-11915/AG/NIA NIH HHS/ -- P01 AG011915/AG/NIA NIH HHS/ -- P01 AG011915-11A29002/AG/NIA NIH HHS/ -- P51 RR000167/RR/NCRR NIH HHS/ -- RR020141-01/RR/NCRR NIH HHS/ -- RR15459-01/RR/NCRR NIH HHS/ -- New York, N.Y. -- Science. 2009 Jul 10;325(5937):201-4. doi: 10.1126/science.1173635.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Wisconsin National Primate Research Center, University of Wisconsin, Madison, WI 53715, USA. rcolman@primate.wisc.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19590001" target="_blank"〉PubMed〈/a〉

    Description: The catalytic engine of RNA interference (RNAi) is the RNA-induced silencing complex (RISC), wherein the endoribonuclease Argonaute and single-stranded small interfering RNA (siRNA) direct target mRNA cleavage. We reconstituted long double-stranded RNA- and duplex siRNA-initiated RISC activities with the use of recombinant Drosophila Dicer-2, R2D2, and Ago2 proteins. We used this core reconstitution system to purify an RNAi regulator that we term C3PO (component 3 promoter of RISC), a complex of Translin and Trax. C3PO is a Mg2+-dependent endoribonuclease that promotes RISC activation by removing siRNA passenger strand cleavage products. These studies establish an in vitro RNAi reconstitution system and identify C3PO as a key activator of the core RNAi machinery.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2855623/" 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/PMC2855623/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Liu, Ying -- Ye, Xuecheng -- Jiang, Feng -- Liang, Chunyang -- Chen, Dongmei -- Peng, Junmin -- Kinch, Lisa N -- Grishin, Nick V -- Liu, Qinghua -- AG025688/AG/NIA NIH HHS/ -- GM078163/GM/NIGMS NIH HHS/ -- GM084010/GM/NIGMS NIH HHS/ -- R01 GM078163/GM/NIGMS NIH HHS/ -- R01 GM078163-03/GM/NIGMS NIH HHS/ -- R01 GM084010/GM/NIGMS NIH HHS/ -- R01 GM084010-02/GM/NIGMS NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2009 Aug 7;325(5941):750-3. doi: 10.1126/science.1176325.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biochemistry, University of Texas Southwestern Medical Center, Dallas, TX 75390, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19661431" target="_blank"〉PubMed〈/a〉

    Description: Despite the costs of mating, females of most taxa mate with multiple males. Polyandrous females are hypothesized to gain genetic benefits for their offspring, but this assumes paternity bias favoring male genotypes that enhance offspring viability. We determined net male genetic effects on female and offspring fitness in a seed beetle and then tested whether fertilization success was biased in favor of high-quality male genotypes in double mating experiments. Contrary to expectations, high-quality male genotypes consistently had a lower postmating fertilization success in two independent assays. Our results imply that sexually antagonistic adaptations have a major and unappreciated influence on male postmating fertilization success. Such genetic variation renders indirect genetic benefits an unlikely driver of the evolution of polyandry.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bilde, Trine -- Foged, Anne -- Schilling, Nadia -- Arnqvist, Goran -- New York, N.Y. -- Science. 2009 Jun 26;324(5935):1705-6. doi: 10.1126/science.1171675.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Ecology and Evolution, Evolutionary Biology Centre, University of Uppsala, Norbyvagen 18d, SE - 752 36 Uppsala, Sweden. trine.bilde@biology.au.dk〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19556506" target="_blank"〉PubMed〈/a〉

    Description: Male animals of many species deploy conditional reproductive strategies that contain distinct alternative phenotypes. Such facultatively expressed male tactics are assumed to be due to a single developmental threshold mechanism switching between the expression of two alternative phenotypes. However, we discovered a clade of dung beetles that commonly expresses two threshold mechanisms, resulting in three alternative phenotypes (male trimorphism). Once recognized, we found trimorphism in other beetle families that involves different types of male weapons. Evidence that insects assumed to be dimorphic can express three facultative male forms suggests that we need to adjust how we think about animal mating systems and the evolution of conditional strategies.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Rowland, J Mark -- Emlen, Douglas J -- New York, N.Y. -- Science. 2009 Feb 6;323(5915):773-6. doi: 10.1126/science.1167345.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biology, University of New Mexico, Albuquerque, NM 87131, USA. rowland@unm.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19197062" target="_blank"〉PubMed〈/a〉

    Description: Bacterial nitric oxide synthases (bNOS) are present in many Gram-positive species and have been demonstrated to synthesize NO from arginine in vitro and in vivo. However, the physiological role of bNOS remains largely unknown. We show that NO generated by bNOS increases the resistance of bacteria to a broad spectrum of antibiotics, enabling the bacteria to survive and share habitats with antibiotic-producing microorganisms. NO-mediated resistance is achieved through both the chemical modification of toxic compounds and the alleviation of the oxidative stress imposed by many antibiotics. Our results suggest that the inhibition of NOS activity may increase the effectiveness of antimicrobial therapy.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2929644/" 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/PMC2929644/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gusarov, Ivan -- Shatalin, Konstantin -- Starodubtseva, Marina -- Nudler, Evgeny -- DP1 OD000799/OD/NIH HHS/ -- DP1 OD000799-02/OD/NIH HHS/ -- DP1 OD000799-03/OD/NIH HHS/ -- DP1 OD000799-04/OD/NIH HHS/ -- New York, N.Y. -- Science. 2009 Sep 11;325(5946):1380-4. doi: 10.1126/science.1175439.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biochemistry, New York University School of Medicine, 550 First Avenue, New York, NY 10016, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19745150" target="_blank"〉PubMed〈/a〉

    Description: Words, grammar, and phonology are linguistically distinct, yet their neural substrates are difficult to distinguish in macroscopic brain regions. We investigated whether they can be separated in time and space at the circuit level using intracranial electrophysiology (ICE), namely by recording local field potentials from populations of neurons using electrodes implanted in language-related brain regions while people read words verbatim or grammatically inflected them (present/past or singular/plural). Neighboring probes within Broca's area revealed distinct neuronal activity for lexical (approximately 200 milliseconds), grammatical (approximately 320 milliseconds), and phonological (approximately 450 milliseconds) processing, identically for nouns and verbs, in a region activated in the same patients and task in functional magnetic resonance imaging. This suggests that a linguistic processing sequence predicted on computational grounds is implemented in the brain in fine-grained spatiotemporally patterned activity.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4030760/" 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/PMC4030760/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Sahin, Ned T -- Pinker, Steven -- Cash, Sydney S -- Schomer, Donald -- Halgren, Eric -- HD18381/HD/NICHD NIH HHS/ -- NS18741/NS/NINDS NIH HHS/ -- NS44623/NS/NINDS NIH HHS/ -- P41 RR014075/RR/NCRR NIH HHS/ -- P41 RR014075-02/RR/NCRR NIH HHS/ -- P41-RR14075/RR/NCRR NIH HHS/ -- R01 HD018381-18/HD/NICHD NIH HHS/ -- R01 NS018741/NS/NINDS NIH HHS/ -- R01 NS018741-22/NS/NINDS NIH HHS/ -- R01 NS044623/NS/NINDS NIH HHS/ -- R01 NS044623-03/NS/NINDS NIH HHS/ -- T32 MH070328-03/MH/NIMH NIH HHS/ -- T32-MH070328/MH/NIMH NIH HHS/ -- New York, N.Y. -- Science. 2009 Oct 16;326(5951):445-9. doi: 10.1126/science.1174481.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Radiology, University of California-San Diego, La Jolla, CA 92037, USA. sahin@post.harvard.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19833971" target="_blank"〉PubMed〈/a〉

    Description: After the domestication of animals and crops in the Near East some 11,000 years ago, farming had reached much of central Europe by 7500 years before the present. The extent to which these early European farmers were immigrants or descendants of resident hunter-gatherers who had adopted farming has been widely debated. We compared new mitochondrial DNA (mtDNA) sequences from late European hunter-gatherer skeletons with those from early farmers and from modern Europeans. We find large genetic differences between all three groups that cannot be explained by population continuity alone. Most (82%) of the ancient hunter-gatherers share mtDNA types that are relatively rare in central Europeans today. Together, these analyses provide persuasive evidence that the first farmers were not the descendants of local hunter-gatherers but immigrated into central Europe at the onset of the Neolithic.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bramanti, B -- Thomas, M G -- Haak, W -- Unterlaender, M -- Jores, P -- Tambets, K -- Antanaitis-Jacobs, I -- Haidle, M N -- Jankauskas, R -- Kind, C-J -- Lueth, F -- Terberger, T -- Hiller, J -- Matsumura, S -- Forster, P -- Burger, J -- New York, N.Y. -- Science. 2009 Oct 2;326(5949):137-40. doi: 10.1126/science.1176869.

    Description: The traditional view that proteins possess absolute functional specificity and a single, fixed structure conflicts with their marked ability to adapt and evolve new functions and structures. We consider an alternative, "avant-garde view" in which proteins are conformationally dynamic and exhibit functional promiscuity. We surmise that these properties are the foundation stones of protein evolvability; they facilitate the divergence of new functions within existing folds and the evolution of entirely new folds. Packing modes of proteins also affect their evolvability, and poorly packed, disordered, and conformationally diverse proteins may exhibit high evolvability. This dynamic view of protein structure, function, and evolvability is extrapolated to describe hypothetical scenarios for the evolution of the early proteins and future research directions in the area of protein dynamism and evolution.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Tokuriki, Nobuhiko -- Tawfik, Dan S -- New York, N.Y. -- Science. 2009 Apr 10;324(5924):203-7. doi: 10.1126/science.1169375.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biological Chemistry, Weizmann Institute of Science, Rehovot 76100, Israel.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19359577" target="_blank"〉PubMed〈/a〉

    Description: Ten-month-old infants persistently search for a hidden object at its initial hiding place even after observing it being hidden at another location. Recent evidence suggests that communicative cues from the experimenter contribute to the emergence of this perseverative search error. We replicated these results with dogs (Canis familiaris), who also commit more search errors in ostensive-communicative (in 75% of the total trials) than in noncommunicative (39%) or nonsocial (17%) hiding contexts. However, comparative investigations suggest that communicative signals serve different functions for dogs and infants, whereas human-reared wolves (Canis lupus) do not show doglike context-dependent differences of search errors. We propose that shared sensitivity to human communicative signals stems from convergent social evolution of the Homo and the Canis genera.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Topal, Jozsef -- Gergely, Gyorgy -- Erdohegyi, Agnes -- Csibra, Gergely -- Miklosi, Adam -- G9715587/Medical Research Council/United Kingdom -- New York, N.Y. -- Science. 2009 Sep 4;325(5945):1269-72. doi: 10.1126/science.1176960.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Research Institute for Psychology, Hungarian Academy of Sciences, 1132 Budapest, Hungary. topaljozsef@gmail.com〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19729660" target="_blank"〉PubMed〈/a〉

    Description: Aging induces gradual yet massive cell death in higher organisms, including annual plants. Even so, the underlying regulatory mechanisms are barely known, despite the long-standing interest in this topic. Here, we demonstrate that ORE1, which is a NAC (NAM, ATAF, and CUC) transcription factor, positively regulates aging-induced cell death in Arabidopsis leaves. ORE1 expression is up-regulated concurrently with leaf aging by EIN2 but is negatively regulated by miR164. miR164 expression gradually decreases with aging through negative regulation by EIN2, which leads to the elaborate up-regulation of ORE1 expression. However, EIN2 still contributes to aging-induced cell death in the absence of ORE1. The trifurcate feed-forward pathway involving ORE1, miR164, and EIN2 provides a highly robust regulation to ensure that aging induces cell death in Arabidopsis leaves.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kim, Jin Hee -- Woo, Hye Ryun -- Kim, Jeongsik -- Lim, Pyung Ok -- Lee, In Chul -- Choi, Seung Hee -- Hwang, Daehee -- Nam, Hong Gil -- New York, N.Y. -- Science. 2009 Feb 20;323(5917):1053-7. doi: 10.1126/science.1166386.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Division of Molecular Life Sciences, Pohang University of Science and Technology, Hyoja-dong, Pohang, Kyungbuk, 790-784, Republic of Korea.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19229035" target="_blank"〉PubMed〈/a〉
