    Description: The understanding of natural and sexual selection requires both field and laboratory studies to exploit the advantages and avoid the disadvantages of each approach. However, studies have tended to be polarized among the types of organisms studied, with vertebrates studied in the field and invertebrates in the lab. We used video monitoring combined with DNA profiling of all of the members of a wild population of field crickets across two generations to capture the factors predicting the reproductive success of males and females. The factors that predict a male's success in gaining mates differ from those that predict how many offspring he has. We confirm the fundamental prediction that males vary more in their reproductive success than females, and we find that females as well as males leave more offspring when they mate with more partners.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Rodriguez-Munoz, R -- Bretman, A -- Slate, J -- Walling, C A -- Tregenza, T -- New York, N.Y. -- Science. 2010 Jun 4;328(5983):1269-72. doi: 10.1126/science.1188102.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Centre for Ecology and Conservation, School of Biosciences, University of Exeter, Cornwall Campus, Penryn TR10 EZ, UK.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20522773" target="_blank"〉PubMed〈/a〉

    Description: Meiotic recombination events cluster into narrow segments of the genome, defined as hotspots. Here, we demonstrate that a major player for hotspot specification is the Prdm9 gene. First, two mouse strains that differ in hotspot usage are polymorphic for the zinc finger DNA binding array of PRDM9. Second, the human consensus PRDM9 allele is predicted to recognize the 13-mer motif enriched at human hotspots; this DNA binding specificity is verified by in vitro studies. Third, allelic variants of PRDM9 zinc fingers are significantly associated with variability in genome-wide hotspot usage among humans. Our results provide a molecular basis for the distribution of meiotic recombination in mammals, in which the binding of PRDM9 to specific DNA sequences targets the initiation of recombination at specific locations in the genome.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4295902/" 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/PMC4295902/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Baudat, F -- Buard, J -- Grey, C -- Fledel-Alon, A -- Ober, C -- Przeworski, M -- Coop, G -- de Massy, B -- 03S1/PHS HHS/ -- GM83098/GM/NIGMS NIH HHS/ -- HD21244/HD/NICHD NIH HHS/ -- HL085197/HL/NHLBI NIH HHS/ -- R01 GM083098/GM/NIGMS NIH HHS/ -- R01 HD021244/HD/NICHD NIH HHS/ -- R01 HL085197/HL/NHLBI NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2010 Feb 12;327(5967):836-40. doi: 10.1126/science.1183439.

    Description: The beta1- and beta2-adrenergic receptors (betaARs) on the surface of cardiomyocytes mediate distinct effects on cardiac function and the development of heart failure by regulating production of the second messenger cyclic adenosine monophosphate (cAMP). The spatial localization in cardiomyocytes of these betaARs, which are coupled to heterotrimeric guanine nucleotide-binding proteins (G proteins), and the functional implications of their localization have been unclear. We combined nanoscale live-cell scanning ion conductance and fluorescence resonance energy transfer microscopy techniques and found that, in cardiomyocytes from healthy adult rats and mice, spatially confined beta2AR-induced cAMP signals are localized exclusively to the deep transverse tubules, whereas functional beta1ARs are distributed across the entire cell surface. In cardiomyocytes derived from a rat model of chronic heart failure, beta2ARs were redistributed from the transverse tubules to the cell crest, which led to diffuse receptor-mediated cAMP signaling. Thus, the redistribution of beta(2)ARs in heart failure changes compartmentation of cAMP and might contribute to the failing myocardial phenotype.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Nikolaev, Viacheslav O -- Moshkov, Alexey -- Lyon, Alexander R -- Miragoli, Michele -- Novak, Pavel -- Paur, Helen -- Lohse, Martin J -- Korchev, Yuri E -- Harding, Sian E -- Gorelik, Julia -- 084064/Wellcome Trust/United Kingdom -- BB/D020875/1/Biotechnology and Biological Sciences Research Council/United Kingdom -- G0500373/Medical Research Council/United Kingdom -- Biotechnology and Biological Sciences Research Council/United Kingdom -- Medical Research Council/United Kingdom -- New York, N.Y. -- Science. 2010 Mar 26;327(5973):1653-7. doi: 10.1126/science.1185988.

    Description: For RNA viruses, rapid viral evolution and the biological similarity of closely related host species have been proposed as key determinants of the occurrence and long-term outcome of cross-species transmission. Using a data set of hundreds of rabies viruses sampled from 23 North American bat species, we present a general framework to quantify per capita rates of cross-species transmission and reconstruct historical patterns of viral establishment in new host species using molecular sequence data. These estimates demonstrate diminishing frequencies of both cross-species transmission and host shifts with increasing phylogenetic distance between bat species. Evolutionary constraints on viral host range indicate that host species barriers may trump the intrinsic mutability of RNA viruses in determining the fate of emerging host-virus interactions.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Streicker, Daniel G -- Turmelle, Amy S -- Vonhof, Maarten J -- Kuzmin, Ivan V -- McCracken, Gary F -- Rupprecht, Charles E -- 0430418/PHS HHS/ -- New York, N.Y. -- Science. 2010 Aug 6;329(5992):676-9. doi: 10.1126/science.1188836.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Rabies Team, Centers for Disease Control and Prevention, Atlanta, GA 30333, USA. dstrike@uga.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20689015" target="_blank"〉PubMed〈/a〉

    Description: CD4(+)Foxp3(+) regulatory T (T(reg)) cells are important for maintaining immune tolerance. Understanding the molecular mechanism that regulates T(reg) differentiation will facilitate the development of effective therapeutic strategies against autoimmune diseases. We report here that the SUMO E3 ligase PIAS1 restricts the differentiation of natural T(reg) cells by maintaining a repressive chromatin state of the Foxp3 promoter. PIAS1 acts by binding to the Foxp3 promoter to recruit DNA methyltransferases and heterochromatin protein 1 for epigenetic modifications. Pias1 deletion caused promoter demethylation, reduced histone H3 methylation at Lys(9), and enhanced promoter accessibility. Consistently, Pias1(-/-) mice displayed an increased natural T(reg) cell population and were resistant to the development of experimental autoimmune encephalomyelitis. Our studies have identified an epigenetic mechanism that negatively regulates the differentiation of natural T(reg) cells.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3043201/" 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/PMC3043201/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Liu, Bin -- Tahk, Samuel -- Yee, Kathleen M -- Fan, Guoping -- Shuai, Ke -- K01 AR52717-01/AR/NIAMS NIH HHS/ -- R01 AI063286/AI/NIAID NIH HHS/ -- R01 AI063286-05/AI/NIAID NIH HHS/ -- R01 GM085797/GM/NIGMS NIH HHS/ -- R01 GM085797-03/GM/NIGMS NIH HHS/ -- R01AI063286/AI/NIAID NIH HHS/ -- R01GM085797/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2010 Oct 22;330(6003):521-5. doi: 10.1126/science.1193787.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Division of Hematology-Oncology, Department of Medicine, 11-934 Factor Building, 10833 Le Conte Avenue, University of California, Los Angeles, Los Angeles, CA 90095, USA. bliu@ucla.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20966256" target="_blank"〉PubMed〈/a〉

    Description: Children's reading achievement is influenced by genetics as well as by family and school environments. The importance of teacher quality as a specific school environmental influence on reading achievement is unknown. We studied first- and second-grade students in Florida from schools representing diverse environments. Comparison of monozygotic and dizygotic twins, differentiating genetic similarities of 100% and 50%, provided an estimate of genetic variance in reading achievement. Teacher quality was measured by how much reading gain the non-twin classmates achieved. The magnitude of genetic variance associated with twins' oral reading fluency increased as the quality of their teacher increased. In circumstances where the teachers are all excellent, the variability in student reading achievement may appear to be largely due to genetics. However, poor teaching impedes the ability of children to reach their potential.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2905841/" 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/PMC2905841/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Taylor, J -- Roehrig, A D -- Soden Hensler, B -- Connor, C M -- Schatschneider, C -- P50 HD052120/HD/NICHD NIH HHS/ -- P50 HD052120-02/HD/NICHD NIH HHS/ -- P50 HD052120-020003/HD/NICHD NIH HHS/ -- P50 HD052120-030003/HD/NICHD NIH HHS/ -- P50 HD052120-040003/HD/NICHD NIH HHS/ -- New York, N.Y. -- Science. 2010 Apr 23;328(5977):512-4. doi: 10.1126/science.1186149.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Psychology, Florida State University, Tallahassee, FL 32306-4301, USA. taylor@psy.fsu.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20413504" target="_blank"〉PubMed〈/a〉

    Description: Most hosts, including humans, are simultaneously or sequentially infected with several parasites. A key question is whether patterns of coinfection arise because infection by one parasite species affects susceptibility to others or because of inherent differences between hosts. We used time-series data from individual hosts in natural populations to analyze patterns of infection risk for a microparasite community, detecting large positive and negative effects of other infections. Patterns remain once variations in host susceptibility and exposure are accounted for. Indeed, effects are typically of greater magnitude, and explain more variation in infection risk, than the effects associated with host and environmental factors more commonly considered in disease studies. We highlight the danger of mistaken inference when considering parasite species in isolation rather than parasite communities.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3033556/" 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/PMC3033556/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Telfer, Sandra -- Lambin, Xavier -- Birtles, Richard -- Beldomenico, Pablo -- Burthe, Sarah -- Paterson, Steve -- Begon, Mike -- 070675/Z/03/Z/Wellcome Trust/United Kingdom -- 075202/Wellcome Trust/United Kingdom -- 075202/Z/04/Z/Wellcome Trust/United Kingdom -- 081705/Wellcome Trust/United Kingdom -- New York, N.Y. -- Science. 2010 Oct 8;330(6001):243-6. doi: 10.1126/science.1190333.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉School of Biological Sciences, University of Liverpool, Crown Street, Liverpool L69 7ZB, UK. s.telfer@abdn.ac.uk〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20929776" target="_blank"〉PubMed〈/a〉

    Description: Many oomycete and fungal plant pathogens are obligate biotrophs, which extract nutrients only from living plant tissue and cannot grow apart from their hosts. Although these pathogens cause substantial crop losses, little is known about the molecular basis or evolution of obligate biotrophy. Here, we report the genome sequence of the oomycete Hyaloperonospora arabidopsidis (Hpa), an obligate biotroph and natural pathogen of Arabidopsis thaliana. In comparison with genomes of related, hemibiotrophic Phytophthora species, the Hpa genome exhibits dramatic reductions in genes encoding (i) RXLR effectors and other secreted pathogenicity proteins, (ii) enzymes for assimilation of inorganic nitrogen and sulfur, and (iii) proteins associated with zoospore formation and motility. These attributes comprise a genomic signature of evolution toward obligate biotrophy.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3971456/" 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/PMC3971456/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Baxter, Laura -- Tripathy, Sucheta -- Ishaque, Naveed -- Boot, Nico -- Cabral, Adriana -- Kemen, Eric -- Thines, Marco -- Ah-Fong, Audrey -- Anderson, Ryan -- Badejoko, Wole -- Bittner-Eddy, Peter -- Boore, Jeffrey L -- Chibucos, Marcus C -- Coates, Mary -- Dehal, Paramvir -- Delehaunty, Kim -- Dong, Suomeng -- Downton, Polly -- Dumas, Bernard -- Fabro, Georgina -- Fronick, Catrina -- Fuerstenberg, Susan I -- Fulton, Lucinda -- Gaulin, Elodie -- Govers, Francine -- Hughes, Linda -- Humphray, Sean -- Jiang, Rays H Y -- Judelson, Howard -- Kamoun, Sophien -- Kyung, Kim -- Meijer, Harold -- Minx, Patrick -- Morris, Paul -- Nelson, Joanne -- Phuntumart, Vipa -- Qutob, Dinah -- Rehmany, Anne -- Rougon-Cardoso, Alejandra -- Ryden, Peter -- Torto-Alalibo, Trudy -- Studholme, David -- Wang, Yuanchao -- Win, Joe -- Wood, Jo -- Clifton, Sandra W -- Rogers, Jane -- Van den Ackerveken, Guido -- Jones, Jonathan D G -- McDowell, John M -- Beynon, Jim -- Tyler, Brett M -- 079643/Wellcome Trust/United Kingdom -- BB/C509123/1/Biotechnology and Biological Sciences Research Council/United Kingdom -- BB/E007120/1/Biotechnology and Biological Sciences Research Council/United Kingdom -- BB/E024815/1/Biotechnology and Biological Sciences Research Council/United Kingdom -- BB/E024882/1/Biotechnology and Biological Sciences Research Council/United Kingdom -- BB/F0161901/Biotechnology and Biological Sciences Research Council/United Kingdom -- BB/G015244/1/Biotechnology and Biological Sciences Research Council/United Kingdom -- EP/F500025/1/Biotechnology and Biological Sciences Research Council/United Kingdom -- T12144/Biotechnology and Biological Sciences Research Council/United Kingdom -- Wellcome Trust/United Kingdom -- New York, N.Y. -- Science. 2010 Dec 10;330(6010):1549-51. doi: 10.1126/science.1195203.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉School of Life Sciences, Warwick University, Wellesbourne, CV35 9EF, UK.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/21148394" target="_blank"〉PubMed〈/a〉

    Description: Gain-of-function mutations in Kir6.2 (KCNJ11), the pore-forming subunit of the adenosine triphosphate (ATP)-sensitive potassium (KATP) channel, cause neonatal diabetes. Many patients also suffer from hypotonia (weak and flaccid muscles) and balance problems. The diabetes arises from suppressed insulin secretion by overactive KATP channels in pancreatic beta-cells, but the source of the motor phenotype is unknown. By using mice carrying a human Kir6.2 mutation (Val59--〉Met59) targeted to either muscle or nerve, we show that analogous motor impairments originate in the central nervous system rather than in muscle or peripheral nerves. We also identify locomotor hyperactivity as a feature of KATP channel overactivity. These findings suggest that drugs targeted against neuronal, rather than muscle, KATP channels are needed to treat the motor deficits and that such drugs require high blood-brain barrier permeability.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Clark, Rebecca H -- McTaggart, James S -- Webster, Richard -- Mannikko, Roope -- Iberl, Michaela -- Sim, Xiu Li -- Rorsman, Patrik -- Glitsch, Maike -- Beeson, David -- Ashcroft, Frances M -- 084655/Wellcome Trust/United Kingdom -- G0701521/Medical Research Council/United Kingdom -- Medical Research Council/United Kingdom -- Wellcome Trust/United Kingdom -- New York, N.Y. -- Science. 2010 Jul 23;329(5990):458-61. doi: 10.1126/science.1186146.

    Description: Optical imaging in vivo with molecular specificity is important in biomedicine because of its high spatial resolution and sensitivity compared with magnetic resonance imaging. Stimulated Raman scattering (SRS) microscopy allows highly sensitive optical imaging based on vibrational spectroscopy without adding toxic or perturbative labels. However, SRS imaging in living animals and humans has not been feasible because light cannot be collected through thick tissues, and motion-blur arises from slow imaging based on backscattered light. In this work, we enable in vivo SRS imaging by substantially enhancing the collection of the backscattered signal and increasing the imaging speed by three orders of magnitude to video rate. This approach allows label-free in vivo imaging of water, lipid, and protein in skin and mapping of penetration pathways of topically applied drugs in mice and humans.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3462359/" 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/PMC3462359/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Saar, Brian G -- Freudiger, Christian W -- Reichman, Jay -- Stanley, C Michael -- Holtom, Gary R -- Xie, X Sunney -- 1R01EB010244-01/EB/NIBIB NIH HHS/ -- R01 EB010244/EB/NIBIB NIH HHS/ -- R01 EB010244-02/EB/NIBIB NIH HHS/ -- New York, N.Y. -- Science. 2010 Dec 3;330(6009):1368-70. doi: 10.1126/science.1197236.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Chemistry and Chemical Biology, Harvard University, Cambridge, MA 02138, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/21127249" target="_blank"〉PubMed〈/a〉

    Description: Fanconi anemia (FA) is caused by mutations in 13 Fanc genes and renders cells hypersensitive to DNA interstrand cross-linking (ICL) agents. A central event in the FA pathway is mono-ubiquitylation of the FANCI-FANCD2 (ID) protein complex. Here, we characterize a previously unrecognized nuclease, Fanconi anemia-associated nuclease 1 (FAN1), that promotes ICL repair in a manner strictly dependent on its ability to accumulate at or near sites of DNA damage and that relies on mono-ubiquitylation of the ID complex. Thus, the mono-ubiquitylated ID complex recruits the downstream repair protein FAN1 and facilitates the repair of DNA interstrand cross-links.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Liu, Ting -- Ghosal, Gargi -- Yuan, Jingsong -- Chen, Junjie -- Huang, Jun -- New York, N.Y. -- Science. 2010 Aug 6;329(5992):693-6. doi: 10.1126/science.1192656.

    Description: Visual, acoustic, and olfactory stimuli associated with a highly charged emotional situation take on the affective qualities of that situation. Where the emotional meaning of a given sensory experience is stored is a matter of debate. We found that excitotoxic lesions of auditory, visual, or olfactory secondary sensory cortices impaired remote, but not recent, fear memories in rats. Amnesia was modality-specific and not due to an interference with sensory or emotional processes. In these sites, memory persistence was dependent on ongoing protein kinase Mzeta activity and was associated with an increased activity of layers II-IV, thus suggesting a synaptic strengthening of corticocortical connections. Lesions of the same areas left intact the memory of sensory stimuli not associated with any emotional charge. We propose that secondary sensory cortices support memory storage and retrieval of sensory stimuli that have acquired a behavioral salience with the experience.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Sacco, Tiziana -- Sacchetti, Benedetto -- New York, N.Y. -- Science. 2010 Aug 6;329(5992):649-56. doi: 10.1126/science.1183165.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Neuroscience, University of Turin, Corso Raffaello 30, I-10125 Turin, Italy.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20689011" target="_blank"〉PubMed〈/a〉

    Description: Ghrelin is a gastric peptide hormone that stimulates weight gain in vertebrates. The biological activities of ghrelin require octanoylation of the peptide on Ser(3), an unusual posttranslational modification that is catalyzed by the enzyme ghrelin O-acyltransferase (GOAT). Here, we describe the design, synthesis, and characterization of GO-CoA-Tat, a peptide-based bisubstrate analog that antagonizes GOAT. GO-CoA-Tat potently inhibits GOAT in vitro, in cultured cells, and in mice. Intraperitoneal administration of GO-CoA-Tat improves glucose tolerance and reduces weight gain in wild-type mice but not in ghrelin-deficient mice, supporting the concept that its beneficial metabolic effects are due specifically to GOAT inhibition. In addition to serving as a research tool for mapping ghrelin actions, GO-CoA-Tat may help pave the way for clinical targeting of GOAT in metabolic diseases.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3068526/" 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/PMC3068526/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Barnett, Brad P -- Hwang, Yousang -- Taylor, Martin S -- Kirchner, Henriette -- Pfluger, Paul T -- Bernard, Vincent -- Lin, Yu-yi -- Bowers, Erin M -- Mukherjee, Chandrani -- Song, Woo-Jin -- Longo, Patti A -- Leahy, Daniel J -- Hussain, Mehboob A -- Tschop, Matthias H -- Boeke, Jef D -- Cole, Philip A -- P01 CA016519/CA/NCI NIH HHS/ -- P01 CA016519-35/CA/NCI NIH HHS/ -- P30 DK079637/DK/NIDDK NIH HHS/ -- P60 DK079637/DK/NIDDK NIH HHS/ -- P60 DK079637-05/DK/NIDDK NIH HHS/ -- R01 DK081472/DK/NIDDK NIH HHS/ -- R01 DK081472-01A1/DK/NIDDK NIH HHS/ -- R01 DK081472-02/DK/NIDDK NIH HHS/ -- R01 DK081472-03/DK/NIDDK NIH HHS/ -- R01 GM062437/GM/NIGMS NIH HHS/ -- R01 GM062437-04/GM/NIGMS NIH HHS/ -- R01 GM062437-11/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2010 Dec 17;330(6011):1689-92. doi: 10.1126/science.1196154.

    Description: The genetics of sex determination remain mysterious in many organisms, including some that are otherwise well studied. Here we report the discovery and analysis of the mating-type locus of the model organism Dictyostelium discoideum. Three forms of a single genetic locus specify this species' three mating types: two versions of the locus are entirely different in sequence, and the third resembles a composite of the other two. Single, unrelated genes are sufficient to determine two of the mating types, whereas homologs of both these genes are required in the composite type. The key genes encode polypeptides that possess no recognizable similarity to established protein families. Sex determination in the social amoebae thus appears to use regulators that are unrelated to any others currently known.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3648785/" 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/PMC3648785/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bloomfield, Gareth -- Skelton, Jason -- Ivens, Alasdair -- Tanaka, Yoshimasa -- Kay, Robert R -- 06724/Wellcome Trust/United Kingdom -- 076964/Wellcome Trust/United Kingdom -- MC_U105115237/Medical Research Council/United Kingdom -- Medical Research Council/United Kingdom -- New York, N.Y. -- Science. 2010 Dec 10;330(6010):1533-6. doi: 10.1126/science.1197423.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Medical Research Council Laboratory of Molecular Biology, Hills Road, Cambridge CB2 0QH, UK. garethb@mrc-lmb.cam.ac.uk〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/21148389" target="_blank"〉PubMed〈/a〉

    Description: Dendritic cells (DCs) play a vital role in initiating robust immunity against pathogens as well as maintaining immunological tolerance to self antigens. However, the intracellular signaling networks that program DCs to become tolerogenic remain unknown. We report here that the Wnt-beta-catenin signaling in intestinal dendritic cells regulates the balance between inflammatory versus regulatory responses in the gut. beta-catenin in intestinal dendritic cells was required for the expression of anti-inflammatory mediators such as retinoic acid-metabolizing enzymes, interleukin-10, and transforming growth factor-beta, and the stimulation of regulatory T cell induction while suppressing inflammatory effector T cells. Furthermore, ablation of beta-catenin expression in DCs enhanced inflammatory responses and disease in a mouse model of inflammatory bowel disease. Thus, beta-catenin signaling programs DCs to a tolerogenic state, limiting the inflammatory response.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3732486/" 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/PMC3732486/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Manicassamy, Santhakumar -- Reizis, Boris -- Ravindran, Rajesh -- Nakaya, Helder -- Salazar-Gonzalez, Rosa Maria -- Wang, Yi-Chong -- Pulendran, Bali -- HHSN266 200700006C/PHS HHS/ -- N01 AI50019/AI/NIAID NIH HHS/ -- N01 AI50025/AI/NIAID NIH HHS/ -- R01 AI048638/AI/NIAID NIH HHS/ -- R01 AI056499/AI/NIAID NIH HHS/ -- R01 DK057665/DK/NIDDK NIH HHS/ -- R01DK057665,/DK/NIDDK NIH HHS/ -- R37 AI048638/AI/NIAID NIH HHS/ -- R37 DK057665/DK/NIDDK NIH HHS/ -- R37AI48638,/AI/NIAID NIH HHS/ -- U19 AI057266/AI/NIAID NIH HHS/ -- U19AI057266,/AI/NIAID NIH HHS/ -- U54 AI057157/AI/NIAID NIH HHS/ -- U54AI057157/AI/NIAID NIH HHS/ -- New York, N.Y. -- Science. 2010 Aug 13;329(5993):849-53. doi: 10.1126/science.1188510.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Emory Vaccine Center, and Yerkes National Primate Research Center, 954 Gatewood Road, Atlanta, GA 30329, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20705860" target="_blank"〉PubMed〈/a〉

    Description: Active invasion of the dendritic tree by action potentials (APs) generated in the axon is essential for associative synaptic plasticity and neuronal ensemble formation. In cortical pyramidal cells (PCs), this AP back-propagation is supported by dendritic voltage-gated Na+ (Nav) channels, whose molecular identity is unknown. Using a highly sensitive electron microscopic immunogold technique, we revealed the presence of the Nav1.6 subunit in hippocampal CA1 PC proximal and distal dendrites. Here, the subunit density is lower by a factor of 35 to 80 than that found in axon initial segments. A gradual decrease in Nav1.6 density along the proximodistal axis of the dendritic tree was also detected without any labeling in dendritic spines. Our results reveal the characteristic subcellular distribution of the Nav1.6 subunit, identifying this molecule as a key substrate enabling dendritic excitability.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3546315/" 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/PMC3546315/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lorincz, Andrea -- Nusser, Zoltan -- 083484/Wellcome Trust/United Kingdom -- 090197/Wellcome Trust/United Kingdom -- Wellcome Trust/United Kingdom -- New York, N.Y. -- Science. 2010 May 14;328(5980):906-9. doi: 10.1126/science.1187958.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratory of Cellular Neurophysiology, Institute of Experimental Medicine, Hungarian Academy of Sciences, 1083 Budapest, Hungary. lorincz@koki.hu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20466935" target="_blank"〉PubMed〈/a〉

    Description: Differences in gene expression may play a major role in speciation and phenotypic diversity. We examined genome-wide differences in transcription factor (TF) binding in several humans and a single chimpanzee by using chromatin immunoprecipitation followed by sequencing. The binding sites of RNA polymerase II (PolII) and a key regulator of immune responses, nuclear factor kappaB (p65), were mapped in 10 lymphoblastoid cell lines, and 25 and 7.5% of the respective binding regions were found to differ between individuals. Binding differences were frequently associated with single-nucleotide polymorphisms and genomic structural variants, and these differences were often correlated with differences in gene expression, suggesting functional consequences of binding variation. Furthermore, comparing PolII binding between humans and chimpanzee suggests extensive divergence in TF binding. Our results indicate that many differences in individuals and species occur at the level of TF binding, and they provide insight into the genetic events responsible for these differences.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2938768/" 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/PMC2938768/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kasowski, Maya -- Grubert, Fabian -- Heffelfinger, Christopher -- Hariharan, Manoj -- Asabere, Akwasi -- Waszak, Sebastian M -- Habegger, Lukas -- Rozowsky, Joel -- Shi, Minyi -- Urban, Alexander E -- Hong, Mi-Young -- Karczewski, Konrad J -- Huber, Wolfgang -- Weissman, Sherman M -- Gerstein, Mark B -- Korbel, Jan O -- Snyder, Michael -- R01 CA077808/CA/NCI NIH HHS/ -- R01 CA077808-09/CA/NCI NIH HHS/ -- T32 GM007205/GM/NIGMS NIH HHS/ -- T32 GM007205-34/GM/NIGMS NIH HHS/ -- T32GM07205/GM/NIGMS NIH HHS/ -- U54 HG004558/HG/NHGRI NIH HHS/ -- U54 HG004558-04/HG/NHGRI NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2010 Apr 9;328(5975):232-5. doi: 10.1126/science.1183621.

    Description: Luminal cells are believed to be the cells of origin for human prostate cancer, because the disease is characterized by luminal cell expansion and the absence of basal cells. Yet functional studies addressing the origin of human prostate cancer have not previously been reported because of a lack of relevant in vivo human models. Here we show that basal cells from primary benign human prostate tissue can initiate prostate cancer in immunodeficient mice. The cooperative effects of AKT, ERG, and androgen receptor in basal cells recapitulated the histological and molecular features of human prostate cancer, with loss of basal cells and expansion of luminal cells expressing prostate-specific antigen and alpha-methylacyl-CoA racemase. Our results demonstrate that histological characterization of cancers does not necessarily correlate with the cellular origins of the disease.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2917982/" 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/PMC2917982/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Goldstein, Andrew S -- Huang, Jiaoti -- Guo, Changyong -- Garraway, Isla P -- Witte, Owen N -- GM07185/GM/NIGMS NIH HHS/ -- P50 CA092131/CA/NCI NIH HHS/ -- P50 CA092131-06/CA/NCI NIH HHS/ -- T32 GM007185/GM/NIGMS NIH HHS/ -- T32 GM007185-35/GM/NIGMS NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2010 Jul 30;329(5991):568-71. doi: 10.1126/science.1189992.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Molecular Biology Institute, University of California, Los Angeles (UCLA), Los Angeles, CA 90095, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20671189" target="_blank"〉PubMed〈/a〉

    Description: Proliferating cells, including cancer cells, require altered metabolism to efficiently incorporate nutrients such as glucose into biomass. The M2 isoform of pyruvate kinase (PKM2) promotes the metabolism of glucose by aerobic glycolysis and contributes to anabolic metabolism. Paradoxically, decreased pyruvate kinase enzyme activity accompanies the expression of PKM2 in rapidly dividing cancer cells and tissues. We demonstrate that phosphoenolpyruvate (PEP), the substrate for pyruvate kinase in cells, can act as a phosphate donor in mammalian cells because PEP participates in the phosphorylation of the glycolytic enzyme phosphoglycerate mutase (PGAM1) in PKM2-expressing cells. We used mass spectrometry to show that the phosphate from PEP is transferred to the catalytic histidine (His11) on human PGAM1. This reaction occurred at physiological concentrations of PEP and produced pyruvate in the absence of PKM2 activity. The presence of histidine-phosphorylated PGAM1 correlated with the expression of PKM2 in cancer cell lines and tumor tissues. Thus, decreased pyruvate kinase activity in PKM2-expressing cells allows PEP-dependent histidine phosphorylation of PGAM1 and may provide an alternate glycolytic pathway that decouples adenosine triphosphate production from PEP-mediated phosphotransfer, allowing for the high rate of glycolysis to support the anabolic metabolism observed in many proliferating cells.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3030121/" 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/PMC3030121/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Vander Heiden, Matthew G -- Locasale, Jason W -- Swanson, Kenneth D -- Sharfi, Hadar -- Heffron, Greg J -- Amador-Noguez, Daniel -- Christofk, Heather R -- Wagner, Gerhard -- Rabinowitz, Joshua D -- Asara, John M -- Cantley, Lewis C -- 1K08CA136983/CA/NCI NIH HHS/ -- 1P01CA120964-01A/CA/NCI NIH HHS/ -- 5 T32 CA009361-28/CA/NCI NIH HHS/ -- 5P30CA006516-43/CA/NCI NIH HHS/ -- K08 CA136983/CA/NCI NIH HHS/ -- K08 CA136983-02/CA/NCI NIH HHS/ -- P01 CA089021/CA/NCI NIH HHS/ -- P01 CA089021-10/CA/NCI NIH HHS/ -- P01 CA120964/CA/NCI NIH HHS/ -- P01 CA120964-01A1/CA/NCI NIH HHS/ -- P01 GM047467/GM/NIGMS NIH HHS/ -- P01 GM047467-20/GM/NIGMS NIH HHS/ -- P01CA089021/CA/NCI NIH HHS/ -- P01GM047467/GM/NIGMS NIH HHS/ -- P30 CA006516/CA/NCI NIH HHS/ -- P30 CA006516-43S1/CA/NCI NIH HHS/ -- R01 AI078063/AI/NIAID NIH HHS/ -- R01 GM056203/GM/NIGMS NIH HHS/ -- R01-GM56302/GM/NIGMS NIH HHS/ -- R21 CA128620/CA/NCI NIH HHS/ -- R21/R33 DK070299/DK/NIDDK NIH HHS/ -- R33 DK070299/DK/NIDDK NIH HHS/ -- R33 DK070299-03/DK/NIDDK NIH HHS/ -- T32 CA009172/CA/NCI NIH HHS/ -- T32 CA009361/CA/NCI NIH HHS/ -- T32 CA009361-28/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 2010 Sep 17;329(5998):1492-9. doi: 10.1126/science.1188015.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Dana Farber Cancer Institute, Harvard Medical School, Boston, MA 02115, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20847263" target="_blank"〉PubMed〈/a〉

    Description: Obesity results from chronic energy surplus and excess lipid storage in white adipose tissue (WAT). In contrast, brown adipose tissue (BAT) efficiently burns lipids through adaptive thermogenesis. Studying mouse models, we show that cyclooxygenase (COX)-2, a rate-limiting enzyme in prostaglandin (PG) synthesis, is a downstream effector of beta-adrenergic signaling in WAT and is required for the induction of BAT in WAT depots. PG shifted the differentiation of defined mesenchymal progenitors toward a brown adipocyte phenotype. Overexpression of COX-2 in WAT induced de novo BAT recruitment in WAT, increased systemic energy expenditure, and protected mice against high-fat diet-induced obesity. Thus, COX-2 appears integral to de novo BAT recruitment, which suggests that the PG pathway regulates systemic energy homeostasis.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Vegiopoulos, Alexandros -- Muller-Decker, Karin -- Strzoda, Daniela -- Schmitt, Iris -- Chichelnitskiy, Evgeny -- Ostertag, Anke -- Berriel Diaz, Mauricio -- Rozman, Jan -- Hrabe de Angelis, Martin -- Nusing, Rolf M -- Meyer, Carola W -- Wahli, Walter -- Klingenspor, Martin -- Herzig, Stephan -- New York, N.Y. -- Science. 2010 May 28;328(5982):1158-61. doi: 10.1126/science.1186034.

    Description: The evolutionary appearance of p53 protein probably preceded its role in tumor suppression, suggesting that there may be unappreciated functions for this protein. Using genetic reporters as proxies to follow in vivo activation of the p53 network in Drosophila, we discovered that the process of meiotic recombination instigates programmed activation of p53 in the germ line. Specifically, double-stranded breaks in DNA generated by the topoisomerase Spo11 provoked functional p53 activity, which was prolonged in cells defective for meiotic DNA repair. This intrinsic stimulus for the p53 regulatory network is highly conserved because Spo11-dependent activation of p53 also occurs in mice. Our findings establish a physiological role for p53 in meiosis and suggest that tumor-suppressive functions may have been co-opted from primordial activities linked to recombination.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2917750/" 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/PMC2917750/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lu, Wan-Jin -- Chapo, Joseph -- Roig, Ignasi -- Abrams, John M -- R01 AA017328/AA/NIAAA NIH HHS/ -- R01 AA017328-03/AA/NIAAA NIH HHS/ -- R01 AA017328-04/AA/NIAAA NIH HHS/ -- R01 GM072124/GM/NIGMS NIH HHS/ -- R01 GM072124-10/GM/NIGMS NIH HHS/ -- R01 GM072124-11/GM/NIGMS NIH HHS/ -- R01 GM072124-12/GM/NIGMS NIH HHS/ -- R01 GM072124-13/GM/NIGMS NIH HHS/ -- R01 GM072124-14A1/GM/NIGMS NIH HHS/ -- R01 GM072124-15/GM/NIGMS NIH HHS/ -- R01 HD040916/HD/NICHD NIH HHS/ -- R01 HD040916-09/HD/NICHD NIH HHS/ -- R01 HD040916-10/HD/NICHD NIH HHS/ -- R01AA017328/AA/NIAAA NIH HHS/ -- R01GM072124/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2010 Jun 4;328(5983):1278-81. doi: 10.1126/science.1185640.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Cell Biology, 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/20522776" target="_blank"〉PubMed〈/a〉

    Description: All insects in the order Hymenoptera have haplodiploid sex determination, in which males emerge from haploid unfertilized eggs and females are diploid. Sex determination in the honeybee Apis mellifera is controlled by the complementary sex determination (csd) locus, but the mechanisms controlling sex determination in other Hymenoptera without csd are unknown. We identified the sex-determination system of the parasitic wasp Nasonia, which has no csd locus. Instead, maternal input of Nasonia vitripennis transformer (Nvtra) messenger RNA, in combination with specific zygotic Nvtra transcription, in which Nvtra autoregulates female-specific splicing, is essential for female development. Our data indicate that males develop as a result of maternal imprinting that prevents zygotic transcription of the maternally derived Nvtra allele in unfertilized eggs. Upon fertilization, zygotic Nvtra transcription is initiated, which autoregulates the female-specific transcript, leading to female development.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Verhulst, Eveline C -- Beukeboom, Leo W -- van de Zande, Louis -- New York, N.Y. -- Science. 2010 Apr 30;328(5978):620-3. doi: 10.1126/science.1185805.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Evolutionary Genetics, Centre for Ecological and Evolutionary Studies, University of Groningen, Netherlands.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20431014" target="_blank"〉PubMed〈/a〉

    Description: Lymphocyte survival during immune responses is controlled by the relative expression of pro- and anti-apoptotic molecules, regulating the magnitude, quality, and duration of the response. We investigated the consequences of deleting genes encoding the anti-apoptotic molecules Mcl1 and Bcl2l1 (Bcl-x(L)) from B cells using an inducible system synchronized with expression of activation-induced cytidine deaminase (Aicda) after immunization. This revealed Mcl1 and not Bcl2l1 to be indispensable for the formation and persistence of germinal centers (GCs). Limiting Mcl1 expression reduced the magnitude of the GC response with an equivalent, but not greater, effect on memory B cell formation and no effect on persistence. Our results identify Mcl1 as the main anti-apoptotic regulator of activated B cell survival and suggest distinct mechanisms controlling survival of GC and memory B cells.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2991396/" 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/PMC2991396/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Vikstrom, Ingela -- Carotta, Sebastian -- Luthje, Katja -- Peperzak, Victor -- Jost, Philipp J -- Glaser, Stefan -- Busslinger, Meinrad -- Bouillet, Philippe -- Strasser, Andreas -- Nutt, Stephen L -- Tarlinton, David M -- CA43540/CA/NCI NIH HHS/ -- CA80188/CA/NCI NIH HHS/ -- R01 CA043540/CA/NCI NIH HHS/ -- R01 CA043540-22/CA/NCI NIH HHS/ -- R01 CA080188-08/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 2010 Nov 19;330(6007):1095-9. doi: 10.1126/science.1191793.

    Description: Metabolic syndrome is a group of obesity-related metabolic abnormalities that increase an individual's risk of developing type 2 diabetes and cardiovascular disease. Here, we show that mice genetically deficient in Toll-like receptor 5 (TLR5), a component of the innate immune system that is expressed in the gut mucosa and that helps defend against infection, exhibit hyperphagia and develop hallmark features of metabolic syndrome, including hyperlipidemia, hypertension, insulin resistance, and increased adiposity. These metabolic changes correlated with changes in the composition of the gut microbiota, and transfer of the gut microbiota from TLR5-deficient mice to wild-type germ-free mice conferred many features of metabolic syndrome to the recipients. Food restriction prevented obesity, but not insulin resistance, in the TLR5-deficient mice. These results support the emerging view that the gut microbiota contributes to metabolic disease and suggest that malfunction of the innate immune system may promote the development of metabolic syndrome.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4714868/" 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/PMC4714868/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Vijay-Kumar, Matam -- Aitken, Jesse D -- Carvalho, Frederic A -- Cullender, Tyler C -- Mwangi, Simon -- Srinivasan, Shanthi -- Sitaraman, Shanthi V -- Knight, Rob -- Ley, Ruth E -- Gewirtz, Andrew T -- DK061417/DK/NIDDK NIH HHS/ -- DK06439/DK/NIDDK NIH HHS/ -- DK083275/DK/NIDDK NIH HHS/ -- K01 DK083275/DK/NIDDK NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2010 Apr 9;328(5975):228-31. doi: 10.1126/science.1179721.

    Description: During embryonic development, many organs form by extensive branching of epithelia through the formation of clefts and buds. In cleft formation, buds are delineated by the conversion of epithelial cell-cell adhesions to cell-matrix adhesions, but the mechanisms of cleft formation are not clear. We have identified Btbd7 as a dynamic regulator of branching morphogenesis. Btbd7 provides a mechanistic link between the extracellular matrix and cleft propagation through its highly focal expression leading to local regulation of Snail2 (Slug), E-cadherin, and epithelial cell motility. Inhibition experiments show that Btbd7 is required for branching of embryonic mammalian salivary glands and lungs. Hence, Btbd7 is a regulatory gene that promotes epithelial tissue remodeling and formation of branched organs.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3412157/" 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/PMC3412157/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Onodera, Tomohiro -- Sakai, Takayoshi -- Hsu, Jeff Chi-feng -- Matsumoto, Kazue -- Chiorini, John A -- Yamada, Kenneth M -- ZIA DE000525-20/Intramural NIH HHS/ -- New York, N.Y. -- Science. 2010 Jul 30;329(5991):562-5. doi: 10.1126/science.1191880.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratory of Cell and Developmental Biology, National Institute of Dental and Craniofacial Research, National Institutes of Health, Bethesda, MD 20892-4370, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20671187" target="_blank"〉PubMed〈/a〉

    Description: Mammalian meiotic recombination, which preferentially occurs at specialized sites called hotspots, ensures the orderly segregation of meiotic chromosomes and creates genetic variation among offspring. A locus on mouse chromosome 17, which controls activation of recombination at multiple distant hotspots, has been mapped within a 181-kilobase interval, three of whose genes can be eliminated as candidates. The remaining gene, Prdm9, codes for a zinc finger containing histone H3K4 trimethylase that is expressed in early meiosis and whose deficiency results in sterility in both sexes. Mus musculus exhibits five alleles of Prdm9; human populations exhibit two predominant alleles and multiple minor alleles. The identification of Prdm9 as a protein regulating mammalian recombination hotspots initiates molecular studies of this important biological control system.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2821451/" 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/PMC2821451/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Parvanov, Emil D -- Petkov, Petko M -- Paigen, Kenneth -- 076468/PHS HHS/ -- 078452/PHS HHS/ -- 083408/PHS HHS/ -- CA 34196/CA/NCI NIH HHS/ -- GM 078643/GM/NIGMS NIH HHS/ -- P30 CA034196-26/CA/NCI NIH HHS/ -- P50 GM076468/GM/NIGMS NIH HHS/ -- P50 GM076468-030004/GM/NIGMS NIH HHS/ -- R01 GM078452/GM/NIGMS NIH HHS/ -- R01 GM078452-02/GM/NIGMS NIH HHS/ -- R01 GM078643/GM/NIGMS NIH HHS/ -- R01 GM078643-03/GM/NIGMS NIH HHS/ -- R01 GM083408/GM/NIGMS NIH HHS/ -- R01 GM083408-02/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2010 Feb 12;327(5967):835. doi: 10.1126/science.1181495.

    Description: When selection favors sexual dimorphism, high-fitness parents often produce low-fitness progeny of the opposite sex. This sexual conflict is thought to overwhelm the genetic benefits of mate choice because preferred males incur a cost through the production of low-fitness daughters. We provide a counterpoint in a lizard (Anolis sagrei) that exhibits sexual conflict over body size. By using mate-choice experiments, we show that female brown anoles produce more sons than daughters via large sires but more daughters than sons via small sires. Measures of progeny fitness in the wild suggest that maximal fitness payoffs can be achieved by shifting offspring production from daughters to sons as sire size increases. These results illustrate how the resolution of sexual conflict can restore the genetic benefits of mate choice.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Cox, Robert M -- Calsbeek, Ryan -- New York, N.Y. -- Science. 2010 Apr 2;328(5974):92-4. doi: 10.1126/science.1185550.

    Description: Genomic imprinting results in preferential gene expression from paternally versus maternally inherited chromosomes. We used a genome-wide approach to uncover sex-specific parent-of-origin allelic effects in the adult mouse brain. Our study identified preferential selection of the maternally inherited X chromosome in glutamatergic neurons of the female cortex. Moreover, analysis of the cortex and hypothalamus identified 347 autosomal genes with sex-specific imprinting features. In the hypothalamus, sex-specific imprinted genes were mostly found in females, which suggests parental influence over the hypothalamic function of daughters. We show that interleukin-18, a gene linked to diseases with sex-specific prevalence, is subject to complex, regional, and sex-specific parental effects in the brain. Parent-of-origin effects thus provide new avenues for investigation of sexual dimorphism in brain function and disease.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2997643/" 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/PMC2997643/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gregg, Christopher -- Zhang, Jiangwen -- Butler, James E -- Haig, David -- Dulac, Catherine -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2010 Aug 6;329(5992):682-5. doi: 10.1126/science.1190831.

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

    Description: Genomic imprinting results in preferential expression of the paternal or maternal allele of certain genes. We have performed a genome-wide characterization of imprinting in the mouse embryonic and adult brain. This approach uncovered parent-of-origin allelic effects of more than 1300 loci. We identified parental bias in the expression of individual genes and of specific transcript isoforms, with differences between brain regions. Many imprinted genes are expressed in neural systems associated with feeding and motivated behaviors, and parental biases preferentially target genetic pathways governing metabolism and cell adhesion. We observed a preferential maternal contribution to gene expression in the developing brain and a major paternal contribution in the adult brain. Thus, parental expression bias emerges as a major mode of epigenetic regulation in the brain.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3005244/" 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/PMC3005244/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gregg, Christopher -- Zhang, Jiangwen -- Weissbourd, Brandon -- Luo, Shujun -- Schroth, Gary P -- Haig, David -- Dulac, Catherine -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2010 Aug 6;329(5992):643-8. doi: 10.1126/science.1190830.

    Description: A hallmark of mitosis is the appearance of high levels of histone phosphorylation, yet the roles of these modifications remain largely unknown. Here, we demonstrate that histone H3 phosphorylated at threonine 3 is directly recognized by an evolutionarily conserved binding pocket in the BIR domain of Survivin, which is a member of the chromosomal passenger complex (CPC). This binding mediates recruitment of the CPC to chromosomes and the resulting activation of its kinase subunit Aurora B. Consistently, modulation of the kinase activity of Haspin, which phosphorylates H3T3, leads to defects in the Aurora B-dependent processes of spindle assembly and inhibition of nuclear reformation. These findings establish a direct cellular role for mitotic histone H3T3 phosphorylation, which is read and translated by the CPC to ensure accurate cell division.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3177562/" 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/PMC3177562/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kelly, Alexander E -- Ghenoiu, Cristina -- Xue, John Z -- Zierhut, Christian -- Kimura, Hiroshi -- Funabiki, Hironori -- GM075249/GM/NIGMS NIH HHS/ -- R01 GM075249/GM/NIGMS NIH HHS/ -- R01 GM075249-01/GM/NIGMS NIH HHS/ -- R01 GM075249-02/GM/NIGMS NIH HHS/ -- R01 GM075249-03/GM/NIGMS NIH HHS/ -- R01 GM075249-04/GM/NIGMS NIH HHS/ -- R01 GM075249-05/GM/NIGMS NIH HHS/ -- R01 GM075249-05S1/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2010 Oct 8;330(6001):235-9. doi: 10.1126/science.1189505.

    Description: Hybrids between species are often sterile or inviable because the long-diverged genomes of their parents cause developmental problems when they come together in a single individual. According to the Dobzhansky-Muller (DM) model, the number of genes involved in these "intrinsic postzygotic incompatibilities" should increase faster than linearly with the divergence time between species. This straightforward prediction of the DM model has remained contentious owing to a lack of explicit tests. Examining two pairs of Drosophila species, we show that the number of genes involved in postzygotic isolation increases at least as fast as the square of the number of substitutions (an index of divergence time) between species. This observation verifies a key prediction of the DM model.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Matute, Daniel R -- Butler, Ian A -- Turissini, David A -- Coyne, Jerry A -- R01GM058260/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2010 Sep 17;329(5998):1518-21. doi: 10.1126/science.1193440.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Ecology and Evolution, The University of Chicago, 1101 East 57th Street, Chicago, IL 60637, USA. dmatute@uchicago.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20847270" target="_blank"〉PubMed〈/a〉

    Description: Shelterin is an essential telomeric protein complex that prevents DNA damage signaling and DNA repair at mammalian chromosome ends. Here we report on the role of the TRF2-interacting factor Rap1, a conserved shelterin subunit of unknown function. We removed Rap1 from mouse telomeres either through gene deletion or by replacing TRF2 with a mutant that does not bind Rap1. Rap1 was dispensable for the essential functions of TRF2--repression of ATM kinase signaling and nonhomologous end joining (NHEJ)--and mice lacking telomeric Rap1 were viable and fertile. However, Rap1 was critical for the repression of homology-directed repair (HDR), which can alter telomere length. The data reveal that HDR at telomeres can take place in the absence of DNA damage foci and underscore the functional compartmentalization within shelterin.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2864730/" 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/PMC2864730/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Sfeir, Agnel -- Kabir, Shaheen -- van Overbeek, Megan -- Celli, Giulia B -- de Lange, Titia -- AG016642/AG/NIA NIH HHS/ -- GM049046/GM/NIGMS NIH HHS/ -- R01 AG016642/AG/NIA NIH HHS/ -- R01 AG016642-01/AG/NIA NIH HHS/ -- R01 AG016642-02/AG/NIA NIH HHS/ -- R01 AG016642-03/AG/NIA NIH HHS/ -- R01 AG016642-04/AG/NIA NIH HHS/ -- R01 AG016642-05/AG/NIA NIH HHS/ -- R01 AG016642-06/AG/NIA NIH HHS/ -- R01 AG016642-07/AG/NIA NIH HHS/ -- R01 AG016642-08/AG/NIA NIH HHS/ -- R01 AG016642-09/AG/NIA NIH HHS/ -- R01 AG016642-10/AG/NIA NIH HHS/ -- R01 AG016642-11/AG/NIA NIH HHS/ -- R01 GM049046/GM/NIGMS NIH HHS/ -- R01 GM049046-07/GM/NIGMS NIH HHS/ -- R01 GM049046-08/GM/NIGMS NIH HHS/ -- R01 GM049046-09/GM/NIGMS NIH HHS/ -- R01 GM049046-10/GM/NIGMS NIH HHS/ -- R01 GM049046-11/GM/NIGMS NIH HHS/ -- R01 GM049046-12/GM/NIGMS NIH HHS/ -- R37 GM049046/GM/NIGMS NIH HHS/ -- R37 GM049046-13/GM/NIGMS NIH HHS/ -- R37 GM049046-14/GM/NIGMS NIH HHS/ -- R37 GM049046-15/GM/NIGMS NIH HHS/ -- R37 GM049046-16/GM/NIGMS NIH HHS/ -- R37 GM049046-17/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2010 Mar 26;327(5973):1657-61. doi: 10.1126/science.1185100.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉The Rockefeller University, 1230 York Avenue, New York, NY 10065, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20339076" target="_blank"〉PubMed〈/a〉

    Description: Legume plants host nitrogen-fixing endosymbiotic Rhizobium bacteria in root nodules. In Medicago truncatula, the bacteria undergo an irreversible (terminal) differentiation mediated by hitherto unidentified plant factors. We demonstrated that these factors are nodule-specific cysteine-rich (NCR) peptides that are targeted to the bacteria and enter the bacterial membrane and cytosol. Obstruction of NCR transport in the dnf1-1 signal peptidase mutant correlated with the absence of terminal bacterial differentiation. On the contrary, ectopic expression of NCRs in legumes devoid of NCRs or challenge of cultured rhizobia with peptides provoked symptoms of terminal differentiation. Because NCRs resemble antimicrobial peptides, our findings reveal a previously unknown innovation of the host plant, which adopts effectors of the innate immune system for symbiosis to manipulate the cell fate of endosymbiotic bacteria.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Van de Velde, Willem -- Zehirov, Grigor -- Szatmari, Agnes -- Debreczeny, Monika -- Ishihara, Hironobu -- Kevei, Zoltan -- Farkas, Attila -- Mikulass, Kata -- Nagy, Andrea -- Tiricz, Hilda -- Satiat-Jeunemaitre, Beatrice -- Alunni, Benoit -- Bourge, Mickael -- Kucho, Ken-ichi -- Abe, Mikiko -- Kereszt, Attila -- Maroti, Gergely -- Uchiumi, Toshiki -- Kondorosi, Eva -- Mergaert, Peter -- New York, N.Y. -- Science. 2010 Feb 26;327(5969):1122-6. doi: 10.1126/science.1184057.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Institut des Sciences du Vegetal, Centre National de la Recherche Scientifique, 91198 Gif-sur-Yvette Cedex, France.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20185722" target="_blank"〉PubMed〈/a〉

    Description: Alzheimer's disease is hypothesized to be caused by an imbalance between beta-amyloid (Abeta) production and clearance that leads to Abeta accumulation in the central nervous system (CNS). Abeta production and clearance are key targets in the development of disease-modifying therapeutic agents for Alzheimer's disease. However, there has not been direct evidence of altered Abeta production or clearance in Alzheimer's disease. By using metabolic labeling, we measured Abeta42 and Abeta40 production and clearance rates in the CNS of participants with Alzheimer's disease and cognitively normal controls. Clearance rates for both Abeta42 and Abeta40 were impaired in Alzheimer's disease compared with controls. On average, there were no differences in Abeta40 or Abeta42 production rates. Thus, the common late-onset form of Alzheimer's disease is characterized by an overall impairment in Abeta clearance.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3073454/" 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/PMC3073454/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Mawuenyega, Kwasi G -- Sigurdson, Wendy -- Ovod, Vitaliy -- Munsell, Ling -- Kasten, Tom -- Morris, John C -- Yarasheski, Kevin E -- Bateman, Randall J -- K08 AG027091/AG/NIA NIH HHS/ -- K08 AG027091-03/AG/NIA NIH HHS/ -- K23 AG030946/AG/NIA NIH HHS/ -- K23 AG030946-04/AG/NIA NIH HHS/ -- P01 AG003991/AG/NIA NIH HHS/ -- P01 AG003991-28/AG/NIA NIH HHS/ -- P01 AG03991/AG/NIA NIH HHS/ -- P30 DK056341/DK/NIDDK NIH HHS/ -- P30 DK056341-10/DK/NIDDK NIH HHS/ -- P41 GM103422/GM/NIGMS NIH HHS/ -- P41 RR000954/RR/NCRR NIH HHS/ -- P41 RR000954-34/RR/NCRR NIH HHS/ -- P50 AG005681/AG/NIA NIH HHS/ -- P50 AG005681-28/AG/NIA NIH HHS/ -- P50 AG05681/AG/NIA NIH HHS/ -- P60 DK020579/DK/NIDDK NIH HHS/ -- P60 DK020579-31/DK/NIDDK NIH HHS/ -- R01 NS065667/NS/NINDS NIH HHS/ -- R01 NS065667-03/NS/NINDS NIH HHS/ -- UL1 RR024992/RR/NCRR NIH HHS/ -- UL1 RR024992-05/RR/NCRR NIH HHS/ -- New York, N.Y. -- Science. 2010 Dec 24;330(6012):1774. doi: 10.1126/science.1197623.

    Description: The maintenance of a progenitor cell population as a reservoir of undifferentiated cells is required for organ development and regeneration. However, the mechanisms by which epithelial progenitor cells are maintained during organogenesis are poorly understood. We report that removal of the parasympathetic ganglion in mouse explant organ culture decreased the number and morphogenesis of keratin 5-positive epithelial progenitor cells. These effects were rescued with an acetylcholine analog. We demonstrate that acetylcholine signaling, via the muscarinic M1 receptor and epidermal growth factor receptor, increased epithelial morphogenesis and proliferation of the keratin 5-positive progenitor cells. Parasympathetic innervation maintained the epithelial progenitor cell population in an undifferentiated state, which was required for organogenesis. This mechanism for epithelial progenitor cell maintenance may be targeted for organ repair or regeneration.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3376907/" 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/PMC3376907/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Knox, S M -- Lombaert, I M A -- Reed, X -- Vitale-Cross, L -- Gutkind, J S -- Hoffman, M P -- Z99 DE999999/Intramural NIH HHS/ -- ZIA DE000707-08/Intramural NIH HHS/ -- ZIA DE000722-04/Intramural NIH HHS/ -- New York, N.Y. -- Science. 2010 Sep 24;329(5999):1645-7. doi: 10.1126/science.1192046.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Matrix and Morphogenesis Unit, Laboratory of Cell and Developmental Biology, National Institute of Dental and Craniofacial Research, NIH, 30 Convent Drive, Bethesda, MD 20892, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20929848" target="_blank"〉PubMed〈/a〉

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

    Description: The rapid dissemination of the 2009 pandemic influenza virus underscores the need for universal influenza vaccines that elicit protective immunity to diverse viral strains. Here, we show that vaccination with plasmid DNA encoding H1N1 influenza hemagglutinin (HA) and boosting with seasonal vaccine or replication-defective adenovirus 5 vector encoding HA stimulated the production of broadly neutralizing influenza antibodies. This prime/boost combination increased the neutralization of diverse H1N1 strains dating from 1934 to 2007 as compared to either component alone and conferred protection against divergent H1N1 viruses in mice and ferrets. These antibodies were directed to the conserved stem region of HA and were also elicited in nonhuman primates. Cross-neutralization of H1N1 subtypes elicited by this approach provides a basis for the development of a universal influenza vaccine for humans.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wei, Chih-Jen -- Boyington, Jeffrey C -- McTamney, Patrick M -- Kong, Wing-Pui -- Pearce, Melissa B -- Xu, Ling -- Andersen, Hanne -- Rao, Srinivas -- Tumpey, Terrence M -- Yang, Zhi-Yong -- Nabel, Gary J -- Intramural NIH HHS/ -- New York, N.Y. -- Science. 2010 Aug 27;329(5995):1060-4. doi: 10.1126/science.1192517.

    Description: Bacteria form communities known as biofilms, which disassemble over time. In our studies outlined here, we found that, before biofilm disassembly, Bacillus subtilis produced a factor that prevented biofilm formation and could break down existing biofilms. The factor was shown to be a mixture of D-leucine, D-methionine, D-tyrosine, and D-tryptophan that could act at nanomolar concentrations. D-amino acid treatment caused the release of amyloid fibers that linked cells in the biofilm together. Mutants able to form biofilms in the presence of D-amino acids contained alterations in a protein (YqxM) required for the formation and anchoring of the fibers to the cell. D-amino acids also prevented biofilm formation by Staphylococcus aureus and Pseudomonas aeruginosa. D-amino acids are produced by many bacteria and, thus, may be a widespread signal for biofilm disassembly.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2921573/" 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/PMC2921573/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kolodkin-Gal, Ilana -- Romero, Diego -- Cao, Shugeng -- Clardy, Jon -- Kolter, Roberto -- Losick, Richard -- CA24487/CA/NCI NIH HHS/ -- GM086258/GM/NIGMS NIH HHS/ -- GM18546/GM/NIGMS NIH HHS/ -- GM58213/GM/NIGMS NIH HHS/ -- R01 GM018568/GM/NIGMS NIH HHS/ -- R01 GM018568-39/GM/NIGMS NIH HHS/ -- R01 GM058213/GM/NIGMS NIH HHS/ -- R01 GM086258/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2010 Apr 30;328(5978):627-9. doi: 10.1126/science.1188628.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Molecular and Cellular Biology, Harvard University, Cambridge, MA 02138, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20431016" target="_blank"〉PubMed〈/a〉

    Description: The heme-copper oxidases (HCOs) accomplish the key event of aerobic respiration; they couple O2 reduction and transmembrane proton pumping. To gain new insights into the still enigmatic process, we structurally characterized a C-family HCO--essential for the pathogenicity of many bacteria--that differs from the two other HCO families, A and B, that have been structurally analyzed. The x-ray structure of the C-family cbb3 oxidase from Pseudomonas stutzeri at 3.2 angstrom resolution shows an electron supply system different from families A and B. Like family-B HCOs, C HCOs have only one pathway, which conducts protons via an alternative tyrosine-histidine cross-link. Structural differences around hemes b and b3 suggest a different redox-driven proton-pumping mechanism and provide clues to explain the higher activity of family-C HCOs at low oxygen concentrations.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Buschmann, Sabine -- Warkentin, Eberhard -- Xie, Hao -- Langer, Julian D -- Ermler, Ulrich -- Michel, Hartmut -- New York, N.Y. -- Science. 2010 Jul 16;329(5989):327-30. doi: 10.1126/science.1187303.

    Description: CKAMP44, identified here by a proteomic approach, is a brain-specific type I transmembrane protein that associates with AMPA receptors in synaptic spines. CKAMP44 expressed in Xenopus oocytes reduced GluA1- and A2-mediated steady-state currents, but did not affect kainate- or N-methyl-D-aspartate (NMDA) receptor-mediated currents. Mouse hippocampal CA1 pyramidal neurons expressed CKAMP44 at low abundance, and overexpression of CKAMP44 led to stronger and faster AMPA receptor desensitization, slower recovery from desensitization, and a reduction in the paired-pulse ratio of AMPA currents. By contrast, dentate gyrus granule cells exhibited strong CKAMP44 expression, and CKAMP44 knockout increased the paired-pulse ratio of AMPA currents in lateral and medial perforant path-granule cell synapses. CKAMP44 thus modulates short-term plasticity at specific excitatory synapses.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉von Engelhardt, Jakob -- Mack, Volker -- Sprengel, Rolf -- Kavenstock, Netta -- Li, Ka Wan -- Stern-Bach, Yael -- Smit, August B -- Seeburg, Peter H -- Monyer, Hannah -- New York, N.Y. -- Science. 2010 Mar 19;327(5972):1518-22. doi: 10.1126/science.1184178.

    Description: Hamilton's theory of inclusive fitness showed how natural selection could lead to behaviors that decrease the relative fitness of the actor and also either benefit (altruism) or harm (spite) other individuals. However, several fundamental issues in the evolution of altruism and spite have remained contentious. Here, we show how recent work has resolved three key debates, helping clarify how Hamilton's theoretical overview links to real-world examples, in organisms ranging from bacteria to humans: Is the evolution of extreme altruism, represented by the sterile workers of social insects, driven by genetics or ecology? Does spite really exist in nature? And, can altruism be favored between individuals who are not close kin but share a "greenbeard" gene for altruism?〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉West, Stuart A -- Gardner, Andy -- New York, N.Y. -- Science. 2010 Mar 12;327(5971):1341-4. doi: 10.1126/science.1178332.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Zoology, Oxford University, South Parks Road, Oxford OX1 3PS, UK. stuart.west@zoo.ox.ac.uk〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20223978" target="_blank"〉PubMed〈/a〉

    Description: We report here genome sequences and comparative analyses of three closely related parasitoid wasps: Nasonia vitripennis, N. giraulti, and N. longicornis. Parasitoids are important regulators of arthropod populations, including major agricultural pests and disease vectors, and Nasonia is an emerging genetic model, particularly for evolutionary and developmental genetics. Key findings include the identification of a functional DNA methylation tool kit; hymenopteran-specific genes including diverse venoms; lateral gene transfers among Pox viruses, Wolbachia, and Nasonia; and the rapid evolution of genes involved in nuclear-mitochondrial interactions that are implicated in speciation. Newly developed genome resources advance Nasonia for genetic research, accelerate mapping and cloning of quantitative trait loci, and will ultimately provide tools and knowledge for further increasing the utility of parasitoids as pest insect-control agents.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2849982/" 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/PMC2849982/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Werren, John H -- Richards, Stephen -- Desjardins, Christopher A -- Niehuis, Oliver -- Gadau, Jurgen -- Colbourne, John K -- Nasonia Genome Working Group -- Beukeboom, Leo W -- Desplan, Claude -- Elsik, Christine G -- Grimmelikhuijzen, Cornelis J P -- Kitts, Paul -- Lynch, Jeremy A -- Murphy, Terence -- Oliveira, Deodoro C S G -- Smith, Christopher D -- van de Zande, Louis -- Worley, Kim C -- Zdobnov, Evgeny M -- Aerts, Maarten -- Albert, Stefan -- Anaya, Victor H -- Anzola, Juan M -- Barchuk, Angel R -- Behura, Susanta K -- Bera, Agata N -- Berenbaum, May R -- Bertossa, Rinaldo C -- Bitondi, Marcia M G -- Bordenstein, Seth R -- Bork, Peer -- Bornberg-Bauer, Erich -- Brunain, Marleen -- Cazzamali, Giuseppe -- Chaboub, Lesley -- Chacko, Joseph -- Chavez, Dean -- Childers, Christopher P -- Choi, Jeong-Hyeon -- Clark, Michael E -- Claudianos, Charles -- Clinton, Rochelle A -- Cree, Andrew G -- Cristino, Alexandre S -- Dang, Phat M -- Darby, Alistair C -- de Graaf, Dirk C -- Devreese, Bart -- Dinh, Huyen H -- Edwards, Rachel -- Elango, Navin -- Elhaik, Eran -- Ermolaeva, Olga -- Evans, Jay D -- Foret, Sylvain -- Fowler, Gerald R -- Gerlach, Daniel -- Gibson, Joshua D -- Gilbert, Donald G -- Graur, Dan -- Grunder, Stefan -- Hagen, Darren E -- Han, Yi -- Hauser, Frank -- Hultmark, Da -- Hunter, Henry C 4th -- Hurst, Gregory D D -- Jhangian, Shalini N -- Jiang, Huaiyang -- Johnson, Reed M -- Jones, Andrew K -- Junier, Thomas -- Kadowaki, Tatsuhiko -- Kamping, Albert -- Kapustin, Yuri -- Kechavarzi, Bobak -- Kim, Jaebum -- Kim, Jay -- Kiryutin, Boris -- Koevoets, Tosca -- Kovar, Christie L -- Kriventseva, Evgenia V -- Kucharski, Robert -- Lee, Heewook -- Lee, Sandra L -- Lees, Kristin -- Lewis, Lora R -- Loehlin, David W -- Logsdon, John M Jr -- Lopez, Jacqueline A -- Lozado, Ryan J -- Maglott, Donna -- Maleszka, Ryszard -- Mayampurath, Anoop -- Mazur, Danielle J -- McClure, Marcella A -- Moore, Andrew D -- Morgan, Margaret B -- Muller, Jean -- Munoz-Torres, Monica C -- Muzny, Donna M -- Nazareth, Lynne V -- Neupert, Susanne -- Nguyen, Ngoc B -- Nunes, Francis M F -- Oakeshott, John G -- Okwuonu, Geoffrey O -- Pannebakker, Bart A -- Pejaver, Vikas R -- Peng, Zuogang -- Pratt, Stephen C -- Predel, Reinhard -- Pu, Ling-Ling -- Ranson, Hilary -- Raychoudhury, Rhitoban -- Rechtsteiner, Andreas -- Reese, Justin T -- Reid, Jeffrey G -- Riddle, Megan -- Robertson, Hugh M -- Romero-Severson, Jeanne -- Rosenberg, Miriam -- Sackton, Timothy B -- Sattelle, David B -- Schluns, Helge -- Schmitt, Thomas -- Schneider, Martina -- Schuler, Andreas -- Schurko, Andrew M -- Shuker, David M -- Simoes, Zila L P -- Sinha, Saurabh -- Smith, Zachary -- Solovyev, Victor -- Souvorov, Alexandre -- Springauf, Andreas -- Stafflinger, Elisabeth -- Stage, Deborah E -- Stanke, Mario -- Tanaka, Yoshiaki -- Telschow, Arndt -- Trent, Carol -- Vattathil, Selina -- Verhulst, Eveline C -- Viljakainen, Lumi -- Wanner, Kevin W -- Waterhouse, Robert M -- Whitfield, James B -- Wilkes, Timothy E -- Williamson, Michael -- Willis, Judith H -- Wolschin, Florian -- Wyder, Stefan -- Yamada, Takuji -- Yi, Soojin V -- Zecher, Courtney N -- Zhang, Lan -- Gibbs, Richard A -- 5R01GM070026-04/GM/NIGMS NIH HHS/ -- 5R01HG000747-14/HG/NHGRI NIH HHS/ -- 5R24GM084917-02/GM/NIGMS NIH HHS/ -- AI028309-13A2/AI/NIAID NIH HHS/ -- R01 AI055624/AI/NIAID NIH HHS/ -- R01 GM064864/GM/NIGMS NIH HHS/ -- R01 GM064864-04/GM/NIGMS NIH HHS/ -- R01 GM064864-05A2/GM/NIGMS NIH HHS/ -- R01 GM070026/GM/NIGMS NIH HHS/ -- R01 GM070026-04S1/GM/NIGMS NIH HHS/ -- R01 GM079484/GM/NIGMS NIH HHS/ -- R01 GM085163/GM/NIGMS NIH HHS/ -- R01 GM085163-01/GM/NIGMS NIH HHS/ -- R01 GM085233/GM/NIGMS NIH HHS/ -- R01 HG000747/HG/NHGRI NIH HHS/ -- R01 HG000747-14/HG/NHGRI NIH HHS/ -- R01GM064864/GM/NIGMS NIH HHS/ -- R24 GM084917/GM/NIGMS NIH HHS/ -- R24 GM084917-01/GM/NIGMS NIH HHS/ -- R24 GM084917-02/GM/NIGMS NIH HHS/ -- U54 HG003273/HG/NHGRI NIH HHS/ -- U54 HG003273-03/HG/NHGRI NIH HHS/ -- Intramural NIH HHS/ -- New York, N.Y. -- Science. 2010 Jan 15;327(5963):343-8. doi: 10.1126/science.1178028.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20075255" target="_blank"〉PubMed〈/a〉

    Description: Humans regulate intergroup conflict through parochial altruism; they self-sacrifice to contribute to in-group welfare and to aggress against competing out-groups. Parochial altruism has distinct survival functions, and the brain may have evolved to sustain and promote in-group cohesion and effectiveness and to ward off threatening out-groups. Here, we have linked oxytocin, a neuropeptide produced in the hypothalamus, to the regulation of intergroup conflict. In three experiments using double-blind placebo-controlled designs, male participants self-administered oxytocin or placebo and made decisions with financial consequences to themselves, their in-group, and a competing out-group. Results showed that oxytocin drives a "tend and defend" response in that it promoted in-group trust and cooperation, and defensive, but not offensive, aggression toward competing out-groups.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉De Dreu, Carsten K W -- Greer, Lindred L -- Handgraaf, Michel J J -- Shalvi, Shaul -- Van Kleef, Gerben A -- Baas, Matthijs -- Ten Velden, Femke S -- Van Dijk, Eric -- Feith, Sander W W -- New York, N.Y. -- Science. 2010 Jun 11;328(5984):1408-11. doi: 10.1126/science.1189047.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Psychology, University of Amsterdam, Roetersstraat 15, 1018 WB Amsterdam, Netherlands. c.k.w.dedreu@uva.nl〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20538951" target="_blank"〉PubMed〈/a〉

    Description: Heterozygous somatic mutations in the genes encoding isocitrate dehydrogenase-1 and -2 (IDH1 and IDH2) were recently discovered in human neoplastic disorders. These mutations disable the enzymes' normal ability to convert isocitrate to 2-ketoglutarate (2-KG) and confer on the enzymes a new function: the ability to convert 2-KG to d-2-hydroxyglutarate (D-2-HG). We have detected heterozygous germline mutations in IDH2 that alter enzyme residue Arg(140) in 15 unrelated patients with d-2-hydroxyglutaric aciduria (D-2-HGA), a rare neurometabolic disorder characterized by supraphysiological levels of D-2-HG. These findings provide additional impetus for investigating the role of D-2-HG in the pathophysiology of metabolic disease and cancer.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kranendijk, Martijn -- Struys, Eduard A -- van Schaftingen, Emile -- Gibson, K Michael -- Kanhai, Warsha A -- van der Knaap, Marjo S -- Amiel, Jeanne -- Buist, Neil R -- Das, Anibh M -- de Klerk, Johannis B -- Feigenbaum, Annette S -- Grange, Dorothy K -- Hofstede, Floris C -- Holme, Elisabeth -- Kirk, Edwin P -- Korman, Stanley H -- Morava, Eva -- Morris, Andrew -- Smeitink, Jan -- Sukhai, Ram N -- Vallance, Hilary -- Jakobs, Cornelis -- Salomons, Gajja S -- New York, N.Y. -- Science. 2010 Oct 15;330(6002):336. doi: 10.1126/science.1192632.

    Description: Group functional connectivity magnetic resonance imaging (fcMRI) studies have documented reliable changes in human functional brain maturity over development. Here we show that support vector machine-based multivariate pattern analysis extracts sufficient information from fcMRI data to make accurate predictions about individuals' brain maturity across development. The use of only 5 minutes of resting-state fcMRI data from 238 scans of typically developing volunteers (ages 7 to 30 years) allowed prediction of individual brain maturity as a functional connectivity maturation index. The resultant functional maturation curve accounted for 55% of the sample variance and followed a nonlinear asymptotic growth curve shape. The greatest relative contribution to predicting individual brain maturity was made by the weakening of short-range functional connections between the adult brain's major functional networks.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3135376/" 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/PMC3135376/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Dosenbach, Nico U F -- Nardos, Binyam -- Cohen, Alexander L -- Fair, Damien A -- Power, Jonathan D -- Church, Jessica A -- Nelson, Steven M -- Wig, Gagan S -- Vogel, Alecia C -- Lessov-Schlaggar, Christina N -- Barnes, Kelly Anne -- Dubis, Joseph W -- Feczko, Eric -- Coalson, Rebecca S -- Pruett, John R Jr -- Barch, Deanna M -- Petersen, Steven E -- Schlaggar, Bradley L -- DA027046/DA/NIDA NIH HHS/ -- EY16336/EY/NEI NIH HHS/ -- HD057076/HD/NICHD NIH HHS/ -- MH62130/MH/NIMH NIH HHS/ -- NS00169011/NS/NINDS NIH HHS/ -- NS053425/NS/NINDS NIH HHS/ -- NS32979/NS/NINDS NIH HHS/ -- NS41255/NS/NINDS NIH HHS/ -- NS46424/NS/NINDS NIH HHS/ -- NS51281/NS/NINDS NIH HHS/ -- NS55582/NS/NINDS NIH HHS/ -- R01 HD057076/HD/NICHD NIH HHS/ -- R01 HD057076-04/HD/NICHD NIH HHS/ -- New York, N.Y. -- Science. 2010 Sep 10;329(5997):1358-61. doi: 10.1126/science.1194144.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Neurology, Washington University School of Medicine, St. Louis, MO 63110, USA. ndosenbach@wustl.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20829489" target="_blank"〉PubMed〈/a〉

    Description: Over the past two decades, HIV resistance to antiretroviral drugs (ARVs) has risen to high levels in the wealthier countries of the world, which are able to afford widespread treatment. We have gained insights into the evolution and transmission dynamics of ARV resistance by designing a biologically complex multistrain network model. With this model, we traced the evolutionary history of ARV resistance in San Francisco and predict its future dynamics. By using classification and regression trees, we identified the key immunologic, virologic, and treatment factors that increase ARV resistance. Our modeling shows that 60% of the currently circulating ARV-resistant strains in San Francisco are capable of causing self-sustaining epidemics, because each individual infected with one of these strains can cause, on average, more than one new resistant infection. It is possible that a new wave of ARV-resistant strains that pose a substantial threat to global public health is emerging.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Smith, Robert J -- Okano, Justin T -- Kahn, James S -- Bodine, Erin N -- Blower, Sally -- K24RR024369/RR/NCRR NIH HHS/ -- P30-AI27763/AI/NIAID NIH HHS/ -- R01 AI041935/AI/NIAID NIH HHS/ -- R18-HS017784/HS/AHRQ HHS/ -- New York, N.Y. -- Science. 2010 Feb 5;327(5966):697-701. doi: 10.1126/science.1180556.

    Description: Self-incompatibility in flowering plants prevents inbreeding and promotes outcrossing to generate genetic diversity. In Solanaceae, a multiallelic gene, S-locus F-box (SLF), was previously shown to encode the pollen determinant in self-incompatibility. It was postulated that an SLF allelic product specifically detoxifies its non-self S-ribonucleases (S-RNases), allelic products of the pistil determinant, inside pollen tubes via the ubiquitin-26S-proteasome system, thereby allowing compatible pollinations. However, it remained puzzling how SLF, with much lower allelic sequence diversity than S-RNase, might have the capacity to recognize a large repertoire of non-self S-RNases. We used in vivo functional assays and protein interaction assays to show that in Petunia, at least three types of divergent SLF proteins function as the pollen determinant, each recognizing a subset of non-self S-RNases. Our findings reveal a collaborative non-self recognition system in plants.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kubo, Ken-ichi -- Entani, Tetsuyuki -- Takara, Akie -- Wang, Ning -- Fields, Allison M -- Hua, Zhihua -- Toyoda, Mamiko -- Kawashima, Shin-ichi -- Ando, Toshio -- Isogai, Akira -- Kao, Teh-hui -- Takayama, Seiji -- New York, N.Y. -- Science. 2010 Nov 5;330(6005):796-9. doi: 10.1126/science.1195243.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Graduate School of Biological Sciences, Nara Institute of Science and Technology, 8916-5 Takayama, Ikoma 630-0192, Japan.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/21051632" target="_blank"〉PubMed〈/a〉

    Description: Queens of ants and bees normally obtain a lifetime supply of sperm on a single day of sexual activity, and sperm competition is expected to occur in lineages where queens receive sperm from multiple males. We compared singly mated (monandrous) and multiply mated (polyandrous) sister groups of ants and bees and show that seminal fluid of polyandrous species has a more positive effect on the survival of a male's own sperm than on other males' sperm. This difference was not observed in the monandrous species, suggesting that incapacitation of competing sperm may have independently evolved in both bees and ants. In Atta leafcutter ants, the negative effect of the seminal fluid of other males was negated by secretion from the queen sperm-storage organ, suggesting that queens may control ejaculate competition after sperm storage.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉den Boer, Susanne P A -- Baer, Boris -- Boomsma, Jacobus J -- New York, N.Y. -- Science. 2010 Mar 19;327(5972):1506-9. doi: 10.1126/science.1184709.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Centre for Social Evolution, Department of Biology, University of Copenhagen, Universitetsparken 15, 2100 Copenhagen, Denmark.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20299595" target="_blank"〉PubMed〈/a〉

    Description: Genetic crosses in many organisms have shown that alleles of unlinked genes generally assort independently of one another during gamete formation. However, variation in chromosome size may affect the process of meiosis and lead to nonindependent assortment of chromosomes. We therefore examined chromosomes with insertions and found that they preferentially segregated away from the X chromosome during meiosis in Caenorhabditis elegans males. Conversely, chromosomes with deletions preferentially segregated with the X chromosome. The degree of segregation bias was significantly associated with the length of the insertion or deletion. Simulations revealed that this segregation bias leads to genome size reduction in hermaphroditic species, a pattern consistent with differences in genome sizes in the genus Caenorhabditis. These results suggest that insertions and deletions may affect chromosome segregation patterns.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wang, John -- Chen, Pei-Jiun -- Wang, George J -- Keller, Laurent -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2010 Jul 16;329(5989):293. doi: 10.1126/science.1190130.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Ecology and Evolution, University of Lausanne, CH-1015 Lausanne, Switzerland.

    Description: Dopamine (DA) has long been implicated in impulsivity, but the precise mechanisms linking human variability in DA signaling to differences in impulsive traits remain largely unknown. By using a dual-scan positron emission tomography approach in healthy human volunteers with amphetamine and the D2/D3 ligand [18F]fallypride, we found that higher levels of trait impulsivity were predicted by diminished midbrain D2/D3 autoreceptor binding and greater amphetamine-induced DA release in the striatum, which was in turn associated with stimulant craving. Path analysis confirmed that the impact of decreased midbrain D2/D3 autoreceptor availability on trait impulsivity is mediated in part through its effect on stimulated striatal DA release.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3161413/" 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/PMC3161413/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Buckholtz, Joshua W -- Treadway, Michael T -- Cowan, Ronald L -- Woodward, Neil D -- Li, Rui -- Ansari, M Sib -- Baldwin, Ronald M -- Schwartzman, Ashley N -- Shelby, Evan S -- Smith, Clarence E -- Kessler, Robert M -- Zald, David H -- R01 DA019670/DA/NIDA NIH HHS/ -- R01 DA019670-04/DA/NIDA NIH HHS/ -- R01DA019670-04/DA/NIDA NIH HHS/ -- T32 MH018921/MH/NIMH NIH HHS/ -- T32 MH018921-22/MH/NIMH NIH HHS/ -- New York, N.Y. -- Science. 2010 Jul 30;329(5991):532. doi: 10.1126/science.1185778.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Psychology, Vanderbilt University, Nashville, TN 37240, USA. joshua.buckholtz@vanderbilt.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20671181" target="_blank"〉PubMed〈/a〉

    Description: Current methods for differentiating isolates of predominant lineages of pathogenic bacteria often do not provide sufficient resolution to define precise relationships. Here, we describe a high-throughput genomics approach that provides a high-resolution view of the epidemiology and microevolution of a dominant strain of methicillin-resistant Staphylococcus aureus (MRSA). This approach reveals the global geographic structure within the lineage, its intercontinental transmission through four decades, and the potential to trace person-to-person transmission within a hospital environment. The ability to interrogate and resolve bacterial populations is applicable to a range of infectious diseases, as well as microbial ecology.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2821690/" 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/PMC2821690/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Harris, Simon R -- Feil, Edward J -- Holden, Matthew T G -- Quail, Michael A -- Nickerson, Emma K -- Chantratita, Narisara -- Gardete, Susana -- Tavares, Ana -- Day, Nick -- Lindsay, Jodi A -- Edgeworth, Jonathan D -- de Lencastre, Herminia -- Parkhill, Julian -- Peacock, Sharon J -- Bentley, Stephen D -- 076964/Wellcome Trust/United Kingdom -- Department of Health/United Kingdom -- Wellcome Trust/United Kingdom -- New York, N.Y. -- Science. 2010 Jan 22;327(5964):469-74. doi: 10.1126/science.1182395.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉The Wellcome Trust Sanger Institute, Wellcome Trust Genome Campus, Hinxton, Cambridge CB10 15A, UK.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20093474" target="_blank"〉PubMed〈/a〉

    Description: Genomes of animals as different as sponges and humans show conservation of global architecture. Here we show that multiple genomic features including transposon diversity, developmental gene repertoire, physical gene order, and intron-exon organization are shattered in the tunicate Oikopleura, belonging to the sister group of vertebrates and retaining chordate morphology. Ancestral architecture of animal genomes can be deeply modified and may therefore be largely nonadaptive. This rapidly evolving animal lineage thus offers unique perspectives on the level of genome plasticity. It also illuminates issues as fundamental as the mechanisms of intron gain.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3760481/" 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/PMC3760481/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Denoeud, France -- Henriet, Simon -- Mungpakdee, Sutada -- Aury, Jean-Marc -- Da Silva, Corinne -- Brinkmann, Henner -- Mikhaleva, Jana -- Olsen, Lisbeth Charlotte -- Jubin, Claire -- Canestro, Cristian -- Bouquet, Jean-Marie -- Danks, Gemma -- Poulain, Julie -- Campsteijn, Coen -- Adamski, Marcin -- Cross, Ismael -- Yadetie, Fekadu -- Muffato, Matthieu -- Louis, Alexandra -- Butcher, Stephen -- Tsagkogeorga, Georgia -- Konrad, Anke -- Singh, Sarabdeep -- Jensen, Marit Flo -- Huynh Cong, Evelyne -- Eikeseth-Otteraa, Helen -- Noel, Benjamin -- Anthouard, Veronique -- Porcel, Betina M -- Kachouri-Lafond, Rym -- Nishino, Atsuo -- Ugolini, Matteo -- Chourrout, Pascal -- Nishida, Hiroki -- Aasland, Rein -- Huzurbazar, Snehalata -- Westhof, Eric -- Delsuc, Frederic -- Lehrach, Hans -- Reinhardt, Richard -- Weissenbach, Jean -- Roy, Scott W -- Artiguenave, Francois -- Postlethwait, John H -- Manak, J Robert -- Thompson, Eric M -- Jaillon, Olivier -- Du Pasquier, Louis -- Boudinot, Pierre -- Liberles, David A -- Volff, Jean-Nicolas -- Philippe, Herve -- Lenhard, Boris -- Roest Crollius, Hugues -- Wincker, Patrick -- Chourrout, Daniel -- Z01 LM000073-12/Intramural NIH HHS/ -- New York, N.Y. -- Science. 2010 Dec 3;330(6009):1381-5. doi: 10.1126/science.1194167.

    Description: Touch is both the first sense to develop and a critical means of information acquisition and environmental manipulation. Physical touch experiences may create an ontological scaffold for the development of intrapersonal and interpersonal conceptual and metaphorical knowledge, as well as a springboard for the application of this knowledge. In six experiments, holding heavy or light clipboards, solving rough or smooth puzzles, and touching hard or soft objects nonconsciously influenced impressions and decisions formed about unrelated people and situations. Among other effects, heavy objects made job candidates appear more important, rough objects made social interactions appear more difficult, and hard objects increased rigidity in negotiations. Basic tactile sensations are thus shown to influence higher social cognitive processing in dimension-specific and metaphor-specific ways.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3005631/" 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/PMC3005631/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ackerman, Joshua M -- Nocera, Christopher C -- Bargh, John A -- MH60767/MH/NIMH NIH HHS/ -- R01 MH060767-10/MH/NIMH NIH HHS/ -- New York, N.Y. -- Science. 2010 Jun 25;328(5986):1712-5. doi: 10.1126/science.1189993.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Sloan School of Management, Massachusetts Institute of Technology, 77 Massachusetts Avenue, E62, Cambridge, MA 02142, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20576894" target="_blank"〉PubMed〈/a〉

    Description: Tibetans have lived at very high altitudes for thousands of years, and they have a distinctive suite of physiological traits that enable them to tolerate environmental hypoxia. These phenotypes are clearly the result of adaptation to this environment, but their genetic basis remains unknown. We report genome-wide scans that reveal positive selection in several regions that contain genes whose products are likely involved in high-altitude adaptation. Positively selected haplotypes of EGLN1 and PPARA were significantly associated with the decreased hemoglobin phenotype that is unique to this highland population. Identification of these genes provides support for previously hypothesized mechanisms of high-altitude adaptation and illuminates the complexity of hypoxia-response pathways in humans.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Simonson, Tatum S -- Yang, Yingzhong -- Huff, Chad D -- Yun, Haixia -- Qin, Ga -- Witherspoon, David J -- Bai, Zhenzhong -- Lorenzo, Felipe R -- Xing, Jinchuan -- Jorde, Lynn B -- Prchal, Josef T -- Ge, RiLi -- 1P01CA108671-01A2/CA/NCI NIH HHS/ -- DK069513/DK/NIDDK NIH HHS/ -- GM059290/GM/NIGMS NIH HHS/ -- HL50077/HL/NHLBI NIH HHS/ -- R00 HG005846/HG/NHGRI NIH HHS/ -- New York, N.Y. -- Science. 2010 Jul 2;329(5987):72-5. doi: 10.1126/science.1189406.

    Description: The biological effects and expected fate of the vast amount of oil in the Gulf of Mexico from the Deepwater Horizon blowout are unknown owing to the depth and magnitude of this event. Here, we report that the dispersed hydrocarbon plume stimulated deep-sea indigenous gamma-Proteobacteria that are closely related to known petroleum degraders. Hydrocarbon-degrading genes coincided with the concentration of various oil contaminants. Changes in hydrocarbon composition with distance from the source and incubation experiments with environmental isolates demonstrated faster-than-expected hydrocarbon biodegradation rates at 5 degrees C. Based on these results, the potential exists for intrinsic bioremediation of the oil plume in the deep-water column without substantial oxygen drawdown.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hazen, Terry C -- Dubinsky, Eric A -- DeSantis, Todd Z -- Andersen, Gary L -- Piceno, Yvette M -- Singh, Navjeet -- Jansson, Janet K -- Probst, Alexander -- Borglin, Sharon E -- Fortney, Julian L -- Stringfellow, William T -- Bill, Markus -- Conrad, Mark E -- Tom, Lauren M -- Chavarria, Krystle L -- Alusi, Thana R -- Lamendella, Regina -- Joyner, Dominique C -- Spier, Chelsea -- Baelum, Jacob -- Auer, Manfred -- Zemla, Marcin L -- Chakraborty, Romy -- Sonnenthal, Eric L -- D'haeseleer, Patrik -- Holman, Hoi-Ying N -- Osman, Shariff -- Lu, Zhenmei -- Van Nostrand, Joy D -- Deng, Ye -- Zhou, Jizhong -- Mason, Olivia U -- New York, N.Y. -- Science. 2010 Oct 8;330(6001):204-8. doi: 10.1126/science.1195979.

    Description: Proton-pumping respiratory complex I is one of the largest and most complicated membrane protein complexes. Its function is critical for efficient energy supply in aerobic cells, and malfunctions are implicated in many neurodegenerative disorders. Here, we report an x-ray crystallographic analysis of mitochondrial complex I. The positions of all iron-sulfur clusters relative to the membrane arm were determined in the complete enzyme complex. The ubiquinone reduction site resides close to 30 angstroms above the membrane domain. The arrangement of functional modules suggests conformational coupling of redox chemistry with proton pumping and essentially excludes direct mechanisms. We suggest that a approximately 60-angstrom-long helical transmission element is critical for transducing conformational energy to proton-pumping elements in the distal module of the membrane arm.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hunte, Carola -- Zickermann, Volker -- Brandt, Ulrich -- New York, N.Y. -- Science. 2010 Jul 23;329(5990):448-51. doi: 10.1126/science.1191046.

    Description: Semiconservative DNA replication ensures the faithful duplication of genetic information during cell divisions. However, how epigenetic information carried by histone modifications propagates through mitotic divisions remains elusive. To address this question, the DNA replication-dependent nucleosome partition pattern must be clarified. Here, we report significant amounts of H3.3-H4 tetramers split in vivo, whereas most H3.1-H4 tetramers remained intact. Inhibiting DNA replication-dependent deposition greatly reduced the level of splitting events, which suggests that (i) the replication-independent H3.3 deposition pathway proceeds largely by cooperatively incorporating two new H3.3-H4 dimers and (ii) the majority of splitting events occurred during replication-dependent deposition. Our results support the idea that "silent" histone modifications within large heterochromatic regions are maintained by copying modifications from neighboring preexisting histones without the need for H3-H4 splitting events.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Xu, Mo -- Long, Chengzu -- Chen, Xiuzhen -- Huang, Chang -- Chen, She -- Zhu, Bing -- New York, N.Y. -- Science. 2010 Apr 2;328(5974):94-8. doi: 10.1126/science.1178994.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Graduate Program, Peking Union Medical College and Chinese Academy of Medical Sciences, Beijing 100730, People's Republic of China.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20360108" target="_blank"〉PubMed〈/a〉

    Description: The 2009 H1N1 swine flu is the first influenza pandemic in decades. The crystal structure of the hemagglutinin from the A/California/04/2009 H1N1 virus shows that its antigenic structure, particularly within the Sa antigenic site, is extremely similar to those of human H1N1 viruses circulating early in the 20th century. The cocrystal structure of the 1918 hemagglutinin with 2D1, an antibody from a survivor of the 1918 Spanish flu that neutralizes both 1918 and 2009 H1N1 viruses, reveals an epitope that is conserved in both pandemic viruses. Thus, antigenic similarity between the 2009 and 1918-like viruses provides an explanation for the age-related immunity to the current influenza pandemic.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2897825/" 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/PMC2897825/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Xu, Rui -- Ekiert, Damian C -- Krause, Jens C -- Hai, Rong -- Crowe, James E Jr -- Wilson, Ian A -- AI057157/AI/NIAID NIH HHS/ -- AI058113/AI/NIAID NIH HHS/ -- GM080209/GM/NIGMS NIH HHS/ -- P01 AI058113/AI/NIAID NIH HHS/ -- P01 AI058113-050002/AI/NIAID NIH HHS/ -- T32 GM080209/GM/NIGMS NIH HHS/ -- T32 GM080209-01A2/GM/NIGMS NIH HHS/ -- U54 AI057157/AI/NIAID NIH HHS/ -- U54 AI057157-06/AI/NIAID NIH HHS/ -- Y1-CO-1020/CO/NCI NIH HHS/ -- Y1-GM-1104/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2010 Apr 16;328(5976):357-60. doi: 10.1126/science.1186430.

    Description: Mirror movements are involuntary contralateral movements that mirror voluntary ones and are often associated with defects in midline crossing of the developing central nervous system. We studied two large families, one French Canadian and one Iranian, in which isolated congenital mirror movements were inherited as an autosomal dominant trait. We found that affected individuals carried protein-truncating mutations in DCC (deleted in colorectal carcinoma), a gene on chromosome 18q21.2 that encodes a receptor for netrin-1, a diffusible protein that helps guide axon growth across the midline. Functional analysis of the mutant DCC protein from the French Canadian family revealed a defect in netrin-1 binding. Thus, DCC has an important role in lateralization of the human nervous system.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Srour, Myriam -- Riviere, Jean-Baptiste -- Pham, Jessica M T -- Dube, Marie-Pierre -- Girard, Simon -- Morin, Steves -- Dion, Patrick A -- Asselin, Geraldine -- Rochefort, Daniel -- Hince, Pascale -- Diab, Sabrina -- Sharafaddinzadeh, Naser -- Chouinard, Sylvain -- Theoret, Hugo -- Charron, Frederic -- Rouleau, Guy A -- New York, N.Y. -- Science. 2010 Apr 30;328(5978):592. doi: 10.1126/science.1186463.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Center of Excellence in Neuromics, Universite de Montreal, Montreal, QC H2L 2W5, Canada.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20431009" target="_blank"〉PubMed〈/a〉

    Description: The anterior prefrontal cortex (APC) confers on humans the ability to simultaneously pursue several goals. How does the brain's motivational system, including the medial frontal cortex (MFC), drive the pursuit of concurrent goals? Using brain imaging, we observed that the left and right MFC, which jointly drive single-task performance according to expected rewards, divide under dual-task conditions: While the left MFC encodes the rewards driving one task, the right MFC concurrently encodes those driving the other task. The same dichotomy was observed in the lateral frontal cortex, whereas the APC combined the rewards driving both tasks. The two frontal lobes thus divide for representing simultaneously two concurrent goals coordinated by the APC. The human frontal function seems limited to driving the pursuit of two concurrent goals simultaneously.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Charron, Sylvain -- Koechlin, Etienne -- New York, N.Y. -- Science. 2010 Apr 16;328(5976):360-3. doi: 10.1126/science.1183614.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Institut National de la Sante et de la Recherche Medicale, Paris F-75654 Cedex 13, France.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20395509" target="_blank"〉PubMed〈/a〉

    Description: Most firefly species (Coleoptera: Lampyridae) use bioluminescent flashes for signaling. In some species, the flashing between males occurs rhythmically and repeatedly (synchronically) with millisecond precision. We studied synchrony's behavioral role in the North American firefly, Photinus carolinus. We placed a female in a virtual environment containing artificial males that flashed at varying degrees of synchrony. Females responded to an average of 82% of synchronous flashes compared with as few as 3% of asynchronous flashes. We conclude that one function of flash synchrony is to facilitate a female's ability to recognize her conspecific male's flashing by eliminating potential visual clutter from other flashing males.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Moiseff, Andrew -- Copeland, Jonathan -- New York, N.Y. -- Science. 2010 Jul 9;329(5988):181. doi: 10.1126/science.1190421.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Physiology and Neurobiology, University of Connecticut, Storrs, CT 06269, USA.

    Description: The cell surface receptor CED-1 mediates apoptotic cell recognition by phagocytic cells, enabling cell corpse clearance in Caenorhabditis elegans. Here, we found that the C. elegans intracellular protein sorting complex, retromer, was required for cell corpse clearance by mediating the recycling of CED-1. Retromer was recruited to the surfaces of phagosomes containing cell corpses, and its loss of function caused defective cell corpse removal. The retromer probably acted through direct interaction with CED-1 in the cell corpse recognition pathway. In the absence of retromer function, CED-1 associated with lysosomes and failed to recycle from phagosomes and cytosol to the plasma membrane. Thus, retromer is an essential mediator of apoptotic cell clearance by regulating phagocytic receptor(s) during cell corpse engulfment.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Chen, Didi -- Xiao, Hui -- Zhang, Kai -- Wang, Bin -- Gao, Zhiyang -- Jian, Youli -- Qi, Xiaying -- Sun, Jianwei -- Miao, Long -- Yang, Chonglin -- New York, N.Y. -- Science. 2010 Mar 5;327(5970):1261-4. doi: 10.1126/science.1184840.

    Description: Residents of the Tibetan Plateau show heritable adaptations to extreme altitude. We sequenced 50 exomes of ethnic Tibetans, encompassing coding sequences of 92% of human genes, with an average coverage of 18x per individual. Genes showing population-specific allele frequency changes, which represent strong candidates for altitude adaptation, were identified. The strongest signal of natural selection came from endothelial Per-Arnt-Sim (PAS) domain protein 1 (EPAS1), a transcription factor involved in response to hypoxia. One single-nucleotide polymorphism (SNP) at EPAS1 shows a 78% frequency difference between Tibetan and Han samples, representing the fastest allele frequency change observed at any human gene to date. This SNP's association with erythrocyte abundance supports the role of EPAS1 in adaptation to hypoxia. Thus, a population genomic survey has revealed a functionally important locus in genetic adaptation to high altitude.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3711608/" 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/PMC3711608/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Yi, Xin -- Liang, Yu -- Huerta-Sanchez, Emilia -- Jin, Xin -- Cuo, Zha Xi Ping -- Pool, John E -- Xu, Xun -- Jiang, Hui -- Vinckenbosch, Nicolas -- Korneliussen, Thorfinn Sand -- Zheng, Hancheng -- Liu, Tao -- He, Weiming -- Li, Kui -- Luo, Ruibang -- Nie, Xifang -- Wu, Honglong -- Zhao, Meiru -- Cao, Hongzhi -- Zou, Jing -- Shan, Ying -- Li, Shuzheng -- Yang, Qi -- Asan -- Ni, Peixiang -- Tian, Geng -- Xu, Junming -- Liu, Xiao -- Jiang, Tao -- Wu, Renhua -- Zhou, Guangyu -- Tang, Meifang -- Qin, Junjie -- Wang, Tong -- Feng, Shuijian -- Li, Guohong -- Huasang -- Luosang, Jiangbai -- Wang, Wei -- Chen, Fang -- Wang, Yading -- Zheng, Xiaoguang -- Li, Zhuo -- Bianba, Zhuoma -- Yang, Ge -- Wang, Xinping -- Tang, Shuhui -- Gao, Guoyi -- Chen, Yong -- Luo, Zhen -- Gusang, Lamu -- Cao, Zheng -- Zhang, Qinghui -- Ouyang, Weihan -- Ren, Xiaoli -- Liang, Huiqing -- Zheng, Huisong -- Huang, Yebo -- Li, Jingxiang -- Bolund, Lars -- Kristiansen, Karsten -- Li, Yingrui -- Zhang, Yong -- Zhang, Xiuqing -- Li, Ruiqiang -- Li, Songgang -- Yang, Huanming -- Nielsen, Rasmus -- Wang, Jun -- Wang, Jian -- R01 HG003229/HG/NHGRI NIH HHS/ -- R01 MH084695/MH/NIMH NIH HHS/ -- R01HG003229/HG/NHGRI NIH HHS/ -- R01MHG084695/PHS HHS/ -- New York, N.Y. -- Science. 2010 Jul 2;329(5987):75-8. doi: 10.1126/science.1190371.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉BGI-Shenzhen, Shenzhen 518083, China.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20595611" target="_blank"〉PubMed〈/a〉

    Description: Chlorophylls are essential for light-harvesting and energy transduction in photosynthesis. Four chemically distinct varieties have been known for the past 60 years. Here we report isolation of a fifth, which we designate chlorophyll f. Its in vitro absorption (706 nanometers) and fluorescence (722 nanometers) maxima are red-shifted compared to all other chlorophylls from oxygenic phototrophs. On the basis of the optical, mass, and nuclear magnetic resonance spectra, we propose that chlorophyll f is [2-formyl]-chlorophyll a (C55H70O6N4Mg). This finding suggests that oxygenic photosynthesis can be extended further into the infrared region and may open associated bioenergy applications.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Chen, Min -- Schliep, Martin -- Willows, Robert D -- Cai, Zheng-Li -- Neilan, Brett A -- Scheer, Hugo -- New York, N.Y. -- Science. 2010 Sep 10;329(5997):1318-9. doi: 10.1126/science.1191127.

    Description: Many plant pathogens, including those in the lineage of the Irish potato famine organism Phytophthora infestans, evolve by host jumps followed by specialization. However, how host jumps affect genome evolution remains largely unknown. To determine the patterns of sequence variation in the P. infestans lineage, we resequenced six genomes of four sister species. This revealed uneven evolutionary rates across genomes with genes in repeat-rich regions showing higher rates of structural polymorphisms and positive selection. These loci are enriched in genes induced in planta, implicating host adaptation in genome evolution. Unexpectedly, genes involved in epigenetic processes formed another class of rapidly evolving residents of the gene-sparse regions. These results demonstrate that dynamic repeat-rich genome compartments underpin accelerated gene evolution following host jumps in this pathogen lineage.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Raffaele, Sylvain -- Farrer, Rhys A -- Cano, Liliana M -- Studholme, David J -- MacLean, Daniel -- Thines, Marco -- Jiang, Rays H Y -- Zody, Michael C -- Kunjeti, Sridhara G -- Donofrio, Nicole M -- Meyers, Blake C -- Nusbaum, Chad -- Kamoun, Sophien -- New York, N.Y. -- Science. 2010 Dec 10;330(6010):1540-3. doi: 10.1126/science.1193070.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉The Sainsbury Laboratory, Norwich Research Park, Norwich NR4 7UH, UK.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/21148391" target="_blank"〉PubMed〈/a〉

    Description: In cases where uninvolved bystanders pay to punish defectors, this behavior has typically been interpreted in terms of group-level rather than individual-level benefits. Male cleaner fish, Labroides dimidiatus, punish their female partner if she cheats while inspecting model clients. Punishment promotes female cooperation and thereby yields direct foraging benefits to the male. Thus, third-party punishment can evolve via self-serving tendencies in a nonhuman species, and this finding may shed light on the evolutionary dynamics of more complex behavior in other animal species, including humans.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Raihani, Nichola J -- Grutter, Alexandra S -- Bshary, Redouan -- New York, N.Y. -- Science. 2010 Jan 8;327(5962):171. doi: 10.1126/science.1183068.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Institute of Zoology, Zoological Society of London, Regent's Park, London NW1 4RY, UK. nichola.raihani@ioz.ac.uk〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20056883" target="_blank"〉PubMed〈/a〉

    Description: Horizontal gene transfer has been postulated to occur between crops to co-occurring parasitic plants, but empirical evidence has been lacking. We present evidence that an HGT event moved a nuclear monocot gene into the genome of the eudicot parasite witchweed (Striga hermonthica), which infects many grass species in Africa. Analysis of expressed sequence tags revealed that the genome of S. hermonthica contains a nuclear gene that is widely conserved among grass species but is not found in other eudicots. Phylogenetically, this gene clusters with sorghum genes, the monocot host of the parasitic weed, suggesting that nuclear genes can be captured by parasitic weeds in nature.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Yoshida, Satoko -- Maruyama, Shinichiro -- Nozaki, Hisayoshi -- Shirasu, Ken -- New York, N.Y. -- Science. 2010 May 28;328(5982):1128. doi: 10.1126/science.1187145.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉RIKEN Plant Science Center, Tsurumi, Yokohama 230-0045, Japan.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20508124" target="_blank"〉PubMed〈/a〉

    Description: Cross-reactive neutralizing antibodies (NAbs) are found in the sera of many HIV-1-infected individuals, but the virologic basis of their neutralization remains poorly understood. We used knowledge of HIV-1 envelope structure to develop antigenically resurfaced glycoproteins specific for the structurally conserved site of initial CD4 receptor binding. These probes were used to identify sera with NAbs to the CD4-binding site (CD4bs) and to isolate individual B cells from such an HIV-1-infected donor. By expressing immunoglobulin genes from individual cells, we identified three monoclonal antibodies, including a pair of somatic variants that neutralized over 90% of circulating HIV-1 isolates. Exceptionally broad HIV-1 neutralization can be achieved with individual antibodies targeted to the functionally conserved CD4bs of glycoprotein 120, an important insight for future HIV-1 vaccine design.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2965066/" 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/PMC2965066/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wu, Xueling -- Yang, Zhi-Yong -- Li, Yuxing -- Hogerkorp, Carl-Magnus -- Schief, William R -- Seaman, Michael S -- Zhou, Tongqing -- Schmidt, Stephen D -- Wu, Lan -- Xu, Ling -- Longo, Nancy S -- McKee, Krisha -- O'Dell, Sijy -- Louder, Mark K -- Wycuff, Diane L -- Feng, Yu -- Nason, Martha -- Doria-Rose, Nicole -- Connors, Mark -- Kwong, Peter D -- Roederer, Mario -- Wyatt, Richard T -- Nabel, Gary J -- Mascola, John R -- Z99 AI999999/Intramural NIH HHS/ -- New York, N.Y. -- Science. 2010 Aug 13;329(5993):856-61. doi: 10.1126/science.1187659.

    Description: Staphylococcus aureus is a major human pathogen that is resistant to numerous antibiotics in clinical use. We found two nonribosomal peptide secondary metabolites--the aureusimines, made by S. aureus--that are not antibiotics, but function as regulators of virulence factor expression and are necessary for productive infections. In vivo mouse models of bacteremia showed that strains of S. aureus unable to produce aureusimines were attenuated and/or cleared from major organs, including the spleen, liver, and heart. Targeting aureusimine synthesis may offer novel leads for anti-infective drugs.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wyatt, Morgan A -- Wang, Wenliang -- Roux, Christelle M -- Beasley, Federico C -- Heinrichs, David E -- Dunman, Paul M -- Magarvey, Nathan A -- MOP-38002/Canadian Institutes of Health Research/Canada -- RA107380/RA/ARRA NIH HHS/ -- New York, N.Y. -- Science. 2010 Jul 16;329(5989):294-6. doi: 10.1126/science.1188888.

    Description: Carotenoids are colored compounds produced by plants, fungi, and microorganisms and are required in the diet of most animals for oxidation control or light detection. Pea aphids display a red-green color polymorphism, which influences their susceptibility to natural enemies, and the carotenoid torulene occurs only in red individuals. Unexpectedly, we found that the aphid genome itself encodes multiple enzymes for carotenoid biosynthesis. Phylogenetic analyses show that these aphid genes are derived from fungal genes, which have been integrated into the genome and duplicated. Red individuals have a 30-kilobase region, encoding a single carotenoid desaturase that is absent from green individuals. A mutation causing an amino acid replacement in this desaturase results in loss of torulene and of red body color. Thus, aphids are animals that make their own carotenoids.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Moran, Nancy A -- Jarvik, Tyler -- New York, N.Y. -- Science. 2010 Apr 30;328(5978):624-7. doi: 10.1126/science.1187113.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Ecology and Evolutionary Biology, 1041 East Lowell Street, University of Arizona, Tucson, AZ 85721, USA. nancy.moran@yale.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20431015" target="_blank"〉PubMed〈/a〉

    Description: In everyday life, many people believe that two heads are better than one. Our ability to solve problems together appears to be fundamental to the current dominance and future survival of the human species. But are two heads really better than one? We addressed this question in the context of a collective low-level perceptual decision-making task. For two observers of nearly equal visual sensitivity, two heads were definitely better than one, provided they were given the opportunity to communicate freely, even in the absence of any feedback about decision outcomes. But for observers with very different visual sensitivities, two heads were actually worse than the better one. These seemingly discrepant patterns of group behavior can be explained by a model in which two heads are Bayes optimal under the assumption that individuals accurately communicate their level of confidence on every trial.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3371582/" 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/PMC3371582/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bahrami, Bahador -- Olsen, Karsten -- Latham, Peter E -- Roepstorff, Andreas -- Rees, Geraint -- Frith, Chris D -- 082334/Wellcome Trust/United Kingdom -- Wellcome Trust/United Kingdom -- New York, N.Y. -- Science. 2010 Aug 27;329(5995):1081-5. doi: 10.1126/science.1185718.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉University College London Institute of Cognitive Neuroscience, University College London, Alexandra House, 17 Queen Square, London WC1N 3AR, UK. bbahrami@gmail.com〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20798320" target="_blank"〉PubMed〈/a〉
