    Histone H2A deubiquitinase activity of the Polycomb repressive complex PR-DUB (2010)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2010-05-04
    Description: Polycomb group (PcG) proteins are transcriptional repressors that control processes ranging from the maintenance of cell fate decisions and stem cell pluripotency in animals to the control of flowering time in plants. In Drosophila, genetic studies identified more than 15 different PcG proteins that are required to repress homeotic (HOX) and other developmental regulator genes in cells where they must stay inactive. Biochemical analyses established that these PcG proteins exist in distinct multiprotein complexes that bind to and modify chromatin of target genes. Among those, Polycomb repressive complex 1 (PRC1) and the related dRing-associated factors (dRAF) complex contain an E3 ligase activity for monoubiquitination of histone H2A (refs 1-4). Here we show that the uncharacterized Drosophila PcG gene calypso encodes the ubiquitin carboxy-terminal hydrolase BAP1. Biochemically purified Calypso exists in a complex with the PcG protein ASX, and this complex, named Polycomb repressive deubiquitinase (PR-DUB), is bound at PcG target genes in Drosophila. Reconstituted recombinant Drosophila and human PR-DUB complexes remove monoubiquitin from H2A but not from H2B in nucleosomes. Drosophila mutants lacking PR-DUB show a strong increase in the levels of monoubiquitinated H2A. A mutation that disrupts the catalytic activity of Calypso, or absence of the ASX subunit abolishes H2A deubiquitination in vitro and HOX gene repression in vivo. Polycomb gene silencing may thus entail a dynamic balance between H2A ubiquitination by PRC1 and dRAF, and H2A deubiquitination by PR-DUB.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3182123/" 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/PMC3182123/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Scheuermann, Johanna C -- de Ayala Alonso, Andres Gaytan -- Oktaba, Katarzyna -- Ly-Hartig, Nga -- McGinty, Robert K -- Fraterman, Sven -- Wilm, Matthias -- Muir, Tom W -- Muller, Jurg -- R01 GM086868/GM/NIGMS NIH HHS/ -- R01 GM086868-13/GM/NIGMS NIH HHS/ -- RC2 CA148354/CA/NCI NIH HHS/ -- RC2 CA148354-02/CA/NCI NIH HHS/ -- RC2CA148354/CA/NCI NIH HHS/ -- England -- Nature. 2010 May 13;465(7295):243-7. doi: 10.1038/nature08966.

    Genome-wide RNAi screen identifies human host factors crucial for influenza virus replication (2010)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2010-01-19
    Description: Influenza A virus, being responsible for seasonal epidemics and reoccurring pandemics, represents a worldwide threat to public health. High mutation rates facilitate the generation of viral escape mutants, rendering vaccines and drugs directed against virus-encoded targets potentially ineffective. In contrast, targeting host cell determinants temporarily dispensable for the host but crucial for virus replication could prevent viral escape. Here we report the discovery of 287 human host cell genes influencing influenza A virus replication in a genome-wide RNA interference (RNAi) screen. Using an independent assay we confirmed 168 hits (59%) inhibiting either the endemic H1N1 (119 hits) or the current pandemic swine-origin (121 hits) influenza A virus strains, with an overlap of 60%. Notably, a subset of these common hits was also essential for replication of a highly pathogenic avian H5N1 strain. In-depth analyses of several factors provided insights into their infection stage relevance. Notably, SON DNA binding protein (SON) was found to be important for normal trafficking of influenza virions to late endosomes early in infection. We also show that a small molecule inhibitor of CDC-like kinase 1 (CLK1) reduces influenza virus replication by more than two orders of magnitude, an effect connected with impaired splicing of the viral M2 messenger RNA. Furthermore, influenza-virus-infected p27(-/-) (cyclin-dependent kinase inhibitor 1B; Cdkn1b) mice accumulated significantly lower viral titres in the lung, providing in vivo evidence for the importance of this gene. Thus, our results highlight the potency of genome-wide RNAi screening for the dissection of virus-host interactions and the identification of drug targets for a broad range of influenza viruses.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Karlas, Alexander -- Machuy, Nikolaus -- Shin, Yujin -- Pleissner, Klaus-Peter -- Artarini, Anita -- Heuer, Dagmar -- Becker, Daniel -- Khalil, Hany -- Ogilvie, Lesley A -- Hess, Simone -- Maurer, Andre P -- Muller, Elke -- Wolff, Thorsten -- Rudel, Thomas -- Meyer, Thomas F -- England -- Nature. 2010 Feb 11;463(7282):818-22. doi: 10.1038/nature08760.

    Origin of the human malaria parasite Plasmodium falciparum in gorillas (2010)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2010-09-25
    Description: Plasmodium falciparum is the most prevalent and lethal of the malaria parasites infecting humans, yet the origin and evolutionary history of this important pathogen remain controversial. Here we develop a single-genome amplification strategy to identify and characterize Plasmodium spp. DNA sequences in faecal samples from wild-living apes. Among nearly 3,000 specimens collected from field sites throughout central Africa, we found Plasmodium infection in chimpanzees (Pan troglodytes) and western gorillas (Gorilla gorilla), but not in eastern gorillas (Gorilla beringei) or bonobos (Pan paniscus). Ape plasmodial infections were highly prevalent, widely distributed and almost always made up of mixed parasite species. Analysis of more than 1,100 mitochondrial, apicoplast and nuclear gene sequences from chimpanzees and gorillas revealed that 99% grouped within one of six host-specific lineages representing distinct Plasmodium species within the subgenus Laverania. One of these from western gorillas comprised parasites that were nearly identical to P. falciparum. In phylogenetic analyses of full-length mitochondrial sequences, human P. falciparum formed a monophyletic lineage within the gorilla parasite radiation. These findings indicate that P. falciparum is of gorilla origin and not of chimpanzee, bonobo or ancient human origin.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2997044/" 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/PMC2997044/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Liu, Weimin -- Li, Yingying -- Learn, Gerald H -- Rudicell, Rebecca S -- Robertson, Joel D -- Keele, Brandon F -- Ndjango, Jean-Bosco N -- Sanz, Crickette M -- Morgan, David B -- Locatelli, Sabrina -- Gonder, Mary K -- Kranzusch, Philip J -- Walsh, Peter D -- Delaporte, Eric -- Mpoudi-Ngole, Eitel -- Georgiev, Alexander V -- Muller, Martin N -- Shaw, George M -- Peeters, Martine -- Sharp, Paul M -- Rayner, Julian C -- Hahn, Beatrice H -- P30 AI 7767/AI/NIAID NIH HHS/ -- P30 AI027767/AI/NIAID NIH HHS/ -- P30 AI027767-21A1/AI/NIAID NIH HHS/ -- R01 AI058715/AI/NIAID NIH HHS/ -- R01 AI058715-06A1/AI/NIAID NIH HHS/ -- R01 AI058715-07/AI/NIAID NIH HHS/ -- R01 AI50529/AI/NIAID NIH HHS/ -- R01 I58715/PHS HHS/ -- R03 AI074778/AI/NIAID NIH HHS/ -- R03 AI074778-02/AI/NIAID NIH HHS/ -- R37 AI050529/AI/NIAID NIH HHS/ -- R37 AI050529-07/AI/NIAID NIH HHS/ -- R37 AI050529-08/AI/NIAID NIH HHS/ -- T32 AI007245/AI/NIAID NIH HHS/ -- T32 AI007245-26/AI/NIAID NIH HHS/ -- T32 GM008111/GM/NIGMS NIH HHS/ -- T32 GM008111-13/GM/NIGMS NIH HHS/ -- U19 AI 067854/AI/NIAID NIH HHS/ -- U19 AI067854/AI/NIAID NIH HHS/ -- U19 AI067854-06/AI/NIAID NIH HHS/ -- Howard Hughes Medical Institute/ -- Wellcome Trust/United Kingdom -- England -- Nature. 2010 Sep 23;467(7314):420-5. doi: 10.1038/nature09442.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Medicine, University of Alabama at Birmingham, Birmingham, Alabama 35294, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20864995" target="_blank"〉PubMed〈/a〉

    Bottom-up effects of plant diversity on multitrophic interactions in a biodiversity experiment (2010)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2010-10-29
    Description: Biodiversity is rapidly declining, and this may negatively affect ecosystem processes, including economically important ecosystem services. Previous studies have shown that biodiversity has positive effects on organisms and processes across trophic levels. However, only a few studies have so far incorporated an explicit food-web perspective. In an eight-year biodiversity experiment, we studied an unprecedented range of above- and below-ground organisms and multitrophic interactions. A multitrophic data set originating from a single long-term experiment allows mechanistic insights that would not be gained from meta-analysis of different experiments. Here we show that plant diversity effects dampen with increasing trophic level and degree of omnivory. This was true both for abundance and species richness of organisms. Furthermore, we present comprehensive above-ground/below-ground biodiversity food webs. Both above ground and below ground, herbivores responded more strongly to changes in plant diversity than did carnivores or omnivores. Density and richness of carnivorous taxa was independent of vegetation structure. Below-ground responses to plant diversity were consistently weaker than above-ground responses. Responses to increasing plant diversity were generally positive, but were negative for biological invasion, pathogen infestation and hyperparasitism. Our results suggest that plant diversity has strong bottom-up effects on multitrophic interaction networks, with particularly strong effects on lower trophic levels. Effects on higher trophic levels are indirectly mediated through bottom-up trophic cascades.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Scherber, Christoph -- Eisenhauer, Nico -- Weisser, Wolfgang W -- Schmid, Bernhard -- Voigt, Winfried -- Fischer, Markus -- Schulze, Ernst-Detlef -- Roscher, Christiane -- Weigelt, Alexandra -- Allan, Eric -- Bessler, Holger -- Bonkowski, Michael -- Buchmann, Nina -- Buscot, Francois -- Clement, Lars W -- Ebeling, Anne -- Engels, Christof -- Halle, Stefan -- Kertscher, Ilona -- Klein, Alexandra-Maria -- Koller, Robert -- Konig, Stephan -- Kowalski, Esther -- Kummer, Volker -- Kuu, Annely -- Lange, Markus -- Lauterbach, Dirk -- Middelhoff, Cornelius -- Migunova, Varvara D -- Milcu, Alexandru -- Muller, Ramona -- Partsch, Stephan -- Petermann, Jana S -- Renker, Carsten -- Rottstock, Tanja -- Sabais, Alexander -- Scheu, Stefan -- Schumacher, Jens -- Temperton, Vicky M -- Tscharntke, Teja -- England -- Nature. 2010 Nov 25;468(7323):553-6. doi: 10.1038/nature09492.

    Encoding of conditioned fear in central amygdala inhibitory circuits (2010)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2010-11-12
    Description: The central amygdala (CEA), a nucleus predominantly composed of GABAergic inhibitory neurons, is essential for fear conditioning. How the acquisition and expression of conditioned fear are encoded within CEA inhibitory circuits is not understood. Using in vivo electrophysiological, optogenetic and pharmacological approaches in mice, we show that neuronal activity in the lateral subdivision of the central amygdala (CEl) is required for fear acquisition, whereas conditioned fear responses are driven by output neurons in the medial subdivision (CEm). Functional circuit analysis revealed that inhibitory CEA microcircuits are highly organized and that cell-type-specific plasticity of phasic and tonic activity in the CEl to CEm pathway may gate fear expression and regulate fear generalization. Our results define the functional architecture of CEA microcircuits and their role in the acquisition and regulation of conditioned fear behaviour.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ciocchi, Stephane -- Herry, Cyril -- Grenier, Francois -- Wolff, Steffen B E -- Letzkus, Johannes J -- Vlachos, Ioannis -- Ehrlich, Ingrid -- Sprengel, Rolf -- Deisseroth, Karl -- Stadler, Michael B -- Muller, Christian -- Luthi, Andreas -- England -- Nature. 2010 Nov 11;468(7321):277-82. doi: 10.1038/nature09559.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Friedrich Miescher Institute for Biomedical Research, Maulbeerstrasse 66, 4058 Basel, Switzerland.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/21068837" target="_blank"〉PubMed〈/a〉

    Phosphorylation of histone H3T6 by PKCbeta(I) controls demethylation at histone H3K4 (2010)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2010-03-17
    Description: Demethylation at distinct lysine residues in histone H3 by lysine-specific demethylase 1 (LSD1) causes either gene repression or activation. As a component of co-repressor complexes, LSD1 contributes to target gene repression by removing mono- and dimethyl marks from lysine 4 of histone H3 (H3K4). In contrast, during androgen receptor (AR)-activated gene expression, LSD1 removes mono- and dimethyl marks from lysine 9 of histone H3 (H3K9). Yet, the mechanisms that control this dual specificity of demethylation are unknown. Here we show that phosphorylation of histone H3 at threonine 6 (H3T6) by protein kinase C beta I (PKCbeta(I), also known as PRKCbeta) is the key event that prevents LSD1 from demethylating H3K4 during AR-dependent gene activation. In vitro, histone H3 peptides methylated at lysine 4 and phosphorylated at threonine 6 are no longer LSD1 substrates. In vivo, PKCbeta(I) co-localizes with AR and LSD1 on target gene promoters and phosphorylates H3T6 after androgen-induced gene expression. RNA interference (RNAi)-mediated knockdown of PKCbeta(I) abrogates H3T6 phosphorylation, enhances demethylation at H3K4, and inhibits AR-dependent transcription. Activation of PKCbeta(I) requires androgen-dependent recruitment of the gatekeeper kinase protein kinase C (PKC)-related kinase 1 (PRK1). Notably, increased levels of PKCbeta(I) and phosphorylated H3T6 (H3T6ph) positively correlate with high Gleason scores of prostate carcinomas, and inhibition of PKCbeta(I) blocks AR-induced tumour cell proliferation in vitro and cancer progression of tumour xenografts in vivo. Together, our data establish that androgen-dependent kinase signalling leads to the writing of the new chromatin mark H3T6ph, which in consequence prevents removal of active methyl marks from H3K4 during AR-stimulated gene expression.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Metzger, Eric -- Imhof, Axel -- Patel, Dharmeshkumar -- Kahl, Philip -- Hoffmeyer, Katrin -- Friedrichs, Nicolaus -- Muller, Judith M -- Greschik, Holger -- Kirfel, Jutta -- Ji, Sujuan -- Kunowska, Natalia -- Beisenherz-Huss, Christian -- Gunther, Thomas -- Buettner, Reinhard -- Schule, Roland -- England -- Nature. 2010 Apr 1;464(7289):792-6. doi: 10.1038/nature08839.

    Structure of the F-actin-tropomyosin complex (2014)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2014-12-04
    Description: Filamentous actin (F-actin) is the major protein of muscle thin filaments, and actin microfilaments are the main component of the eukaryotic cytoskeleton. Mutations in different actin isoforms lead to early-onset autosomal dominant non-syndromic hearing loss, familial thoracic aortic aneurysms and dissections, and multiple variations of myopathies. In striated muscle fibres, the binding of myosin motors to actin filaments is mainly regulated by tropomyosin and troponin. Tropomyosin also binds to F-actin in smooth muscle and in non-muscle cells and stabilizes and regulates the filaments there in the absence of troponin. Although crystal structures for monomeric actin (G-actin) are available, a high-resolution structure of F-actin is still missing, hampering our understanding of how disease-causing mutations affect the function of thin muscle filaments and microfilaments. Here we report the three-dimensional structure of F-actin at a resolution of 3.7 A in complex with tropomyosin at a resolution of 6.5 A, determined by electron cryomicroscopy. The structure reveals that the D-loop is ordered and acts as a central region for hydrophobic and electrostatic interactions that stabilize the F-actin filament. We clearly identify map density corresponding to ADP and Mg(2+) and explain the possible effect of prominent disease-causing mutants. A comparison of F-actin with G-actin reveals the conformational changes during filament formation and identifies the D-loop as their key mediator. We also confirm that negatively charged tropomyosin interacts with a positively charged groove on F-actin. Comparison of the position of tropomyosin in F-actin-tropomyosin with its position in our previously determined F-actin-tropomyosin-myosin structure reveals a myosin-induced transition of tropomyosin. Our results allow us to understand the role of individual mutations in the genesis of actin- and tropomyosin-related diseases and will serve as a strong foundation for the targeted development of drugs.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4477711/" 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/PMC4477711/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉von der Ecken, Julian -- Muller, Mirco -- Lehman, William -- Manstein, Dietmar J -- Penczek, Pawel A -- Raunser, Stefan -- R01 60635/PHS HHS/ -- R01 GM060635/GM/NIGMS NIH HHS/ -- R37HL036153/HL/NHLBI NIH HHS/ -- U54 094598/PHS HHS/ -- U54 GM094598/GM/NIGMS NIH HHS/ -- England -- Nature. 2015 Mar 5;519(7541):114-7. doi: 10.1038/nature14033.

    Cyclooxygenase-2 controls energy homeostasis in mice by de novo recruitment of brown adipocytes (2010)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2010-05-08
    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: 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〉
