    Description: We present a DNA library preparation method that has allowed us to reconstruct a high-coverage (30x) genome sequence of a Denisovan, an extinct relative of Neandertals. The quality of this genome allows a direct estimation of Denisovan heterozygosity indicating that genetic diversity in these archaic hominins was extremely low. It also allows tentative dating of the specimen on the basis of "missing evolution" in its genome, detailed measurements of Denisovan and Neandertal admixture into present-day human populations, and the generation of a near-complete catalog of genetic changes that swept to high frequency in modern humans since their divergence from Denisovans.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3617501/" 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/PMC3617501/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Meyer, Matthias -- Kircher, Martin -- Gansauge, Marie-Theres -- Li, Heng -- Racimo, Fernando -- Mallick, Swapan -- Schraiber, Joshua G -- Jay, Flora -- Prufer, Kay -- de Filippo, Cesare -- Sudmant, Peter H -- Alkan, Can -- Fu, Qiaomei -- Do, Ron -- Rohland, Nadin -- Tandon, Arti -- Siebauer, Michael -- Green, Richard E -- Bryc, Katarzyna -- Briggs, Adrian W -- Stenzel, Udo -- Dabney, Jesse -- Shendure, Jay -- Kitzman, Jacob -- Hammer, Michael F -- Shunkov, Michael V -- Derevianko, Anatoli P -- Patterson, Nick -- Andres, Aida M -- Eichler, Evan E -- Slatkin, Montgomery -- Reich, David -- Kelso, Janet -- Paabo, Svante -- GM100233/GM/NIGMS NIH HHS/ -- R01 GM040282/GM/NIGMS NIH HHS/ -- R01 GM100233/GM/NIGMS NIH HHS/ -- R01-GM40282/GM/NIGMS NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2012 Oct 12;338(6104):222-6. doi: 10.1126/science.1224344.

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

    Description: Development of fertilization-competent oocytes depends on integrated processes controlling meiosis, cytoplasmic development, and maintenance of genomic integrity. We show that meiosis arrest female 1 (MARF1) is required for these processes in mammalian oocytes. Mutations of Marf1 cause female infertility characterized by up-regulation of a cohort of transcripts, increased retrotransposon expression, defective cytoplasmic maturation, and meiotic arrest. Up-regulation of protein phosphatase 2 catalytic subunit (PPP2CB) is key to the meiotic arrest phenotype. Moreover, Iap and Line1 retrotransposon messenger RNAs are also up-regulated, and, concomitantly, DNA double-strand breaks are elevated in mutant oocytes. Therefore MARF1, by suppressing levels of specific transcripts, is an essential regulator of important oogenic processes leading to female fertility and the development of healthy offspring.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3612990/" 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/PMC3612990/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Su, You-Qiang -- Sugiura, Koji -- Sun, Fengyun -- Pendola, Janice K -- Cox, Gregory A -- Handel, Mary Ann -- Schimenti, John C -- Eppig, John J -- CA34196/CA/NCI NIH HHS/ -- HD42137/HD/NICHD NIH HHS/ -- P01 HD042137/HD/NICHD NIH HHS/ -- P30 CA034196/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 2012 Mar 23;335(6075):1496-9. doi: 10.1126/science.1214680.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉The Jackson Laboratory, Bar Harbor, ME 04609, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/22442484" target="_blank"〉PubMed〈/a〉

    Description: Highly pathogenic avian influenza A/H5N1 virus can cause morbidity and mortality in humans but thus far has not acquired the ability to be transmitted by aerosol or respiratory droplet ("airborne transmission") between humans. To address the concern that the virus could acquire this ability under natural conditions, we genetically modified A/H5N1 virus by site-directed mutagenesis and subsequent serial passage in ferrets. The genetically modified A/H5N1 virus acquired mutations during passage in ferrets, ultimately becoming airborne transmissible in ferrets. None of the recipient ferrets died after airborne infection with the mutant A/H5N1 viruses. Four amino acid substitutions in the host receptor-binding protein hemagglutinin, and one in the polymerase complex protein basic polymerase 2, were consistently present in airborne-transmitted viruses. The transmissible viruses were sensitive to the antiviral drug oseltamivir and reacted well with antisera raised against H5 influenza vaccine strains. Thus, avian A/H5N1 influenza viruses can acquire the capacity for airborne transmission between mammals without recombination in an intermediate host and therefore constitute a risk for human pandemic influenza.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Herfst, Sander -- Schrauwen, Eefje J A -- Linster, Martin -- Chutinimitkul, Salin -- de Wit, Emmie -- Munster, Vincent J -- Sorrell, Erin M -- Bestebroer, Theo M -- Burke, David F -- Smith, Derek J -- Rimmelzwaan, Guus F -- Osterhaus, Albert D M E -- Fouchier, Ron A M -- DP1-OD000490-01/OD/NIH HHS/ -- HHSN266200700010C/PHS HHS/ -- New York, N.Y. -- Science. 2012 Jun 22;336(6088):1534-41. doi: 10.1126/science.1213362.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Virology, Erasmus Medical Center, Rotterdam, The Netherlands.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/22723413" target="_blank"〉PubMed〈/a〉

    Description: Protein phosphorylation is a fundamental mechanism regulating nearly every aspect of cellular life. Several secreted proteins are phosphorylated, but the kinases responsible are unknown. We identified a family of atypical protein kinases that localize within the Golgi apparatus and are secreted. Fam20C appears to be the Golgi casein kinase that phosphorylates secretory pathway proteins within S-x-E motifs. Fam20C phosphorylates the caseins and several secreted proteins implicated in biomineralization, including the small integrin-binding ligand, N-linked glycoproteins (SIBLINGs). Consequently, mutations in Fam20C cause an osteosclerotic bone dysplasia in humans known as Raine syndrome. Fam20C is thus a protein kinase dedicated to the phosphorylation of extracellular proteins.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3754843/" 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/PMC3754843/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Tagliabracci, Vincent S -- Engel, James L -- Wen, Jianzhong -- Wiley, Sandra E -- Worby, Carolyn A -- Kinch, Lisa N -- Xiao, Junyu -- Grishin, Nick V -- Dixon, Jack E -- DK018024-37/DK/NIDDK NIH HHS/ -- DK018849-36/DK/NIDDK NIH HHS/ -- GM094575/GM/NIGMS NIH HHS/ -- R01 DK018849/DK/NIDDK NIH HHS/ -- R37 DK018024/DK/NIDDK NIH HHS/ -- T32 CA009523/CA/NCI NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2012 Jun 1;336(6085):1150-3. doi: 10.1126/science.1217817.

    Description: Most living species exploit a limited range of resources. However, little is known about how tight associations build up during evolution between such specialist species and the hosts they use. We examined the dependence of Drosophila pachea on its single host, the senita cactus. Several amino acid changes in the Neverland oxygenase rendered D. pachea unable to transform cholesterol into 7-dehydrocholesterol (the first reaction in the steroid hormone biosynthetic pathway in insects) and thus made D. pachea dependent on the uncommon sterols of its host plant. The neverland mutations increase survival on the cactus's unusual sterols and are in a genomic region that faced recent positive selection. This study illustrates how relatively few genetic changes in a single gene may restrict the ecological niche of a species.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4729188/" 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/PMC4729188/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lang, Michael -- Murat, Sophie -- Clark, Andrew G -- Gouppil, Geraldine -- Blais, Catherine -- Matzkin, Luciano M -- Guittard, Emilie -- Yoshiyama-Yanagawa, Takuji -- Kataoka, Hiroshi -- Niwa, Ryusuke -- Lafont, Rene -- Dauphin-Villemant, Chantal -- Orgogozo, Virginie -- AI064950/AI/NIAID NIH HHS/ -- R01 AI064950/AI/NIAID NIH HHS/ -- R01 HG003229/HG/NHGRI NIH HHS/ -- New York, N.Y. -- Science. 2012 Sep 28;337(6102):1658-61.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉CNRS UMR7592, Universite Paris Diderot, Sorbonne Paris Cite, Institut Jacques Monod, Paris, France.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/23019649" target="_blank"〉PubMed〈/a〉

    Description: The transport of pyruvate, the end product of glycolysis, into mitochondria is an essential process that provides the organelle with a major oxidative fuel. Although the existence of a specific mitochondrial pyruvate carrier (MPC) has been anticipated, its molecular identity remained unknown. We report that MPC is a heterocomplex formed by two members of a family of previously uncharacterized membrane proteins that are conserved from yeast to mammals. Members of the MPC family were found in the inner mitochondrial membrane, and yeast mutants lacking MPC proteins showed severe defects in mitochondrial pyruvate uptake. Coexpression of mouse MPC1 and MPC2 in Lactococcus lactis promoted transport of pyruvate across the membrane. These observations firmly establish these proteins as essential components of the MPC.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Herzig, Sebastien -- Raemy, Etienne -- Montessuit, Sylvie -- Veuthey, Jean-Luc -- Zamboni, Nicola -- Westermann, Benedikt -- Kunji, Edmund R S -- Martinou, Jean-Claude -- MC_U105663139/Medical Research Council/United Kingdom -- New York, N.Y. -- Science. 2012 Jul 6;337(6090):93-6. doi: 10.1126/science.1218530.

    Description: Identification of broadly neutralizing antibodies against influenza A viruses has raised hopes for the development of monoclonal antibody-based immunotherapy and "universal" vaccines for influenza. However, a substantial part of the annual flu burden is caused by two cocirculating, antigenically distinct lineages of influenza B viruses. Here, we report human monoclonal antibodies, CR8033, CR8071, and CR9114, that protect mice against lethal challenge from both lineages. Antibodies CR8033 and CR8071 recognize distinct conserved epitopes in the head region of the influenza B hemagglutinin (HA), whereas CR9114 binds a conserved epitope in the HA stem and protects against lethal challenge with influenza A and B viruses. These antibodies may inform on development of monoclonal antibody-based treatments and a universal flu vaccine for all influenza A and B viruses.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3538841/" 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/PMC3538841/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Dreyfus, Cyrille -- Laursen, Nick S -- Kwaks, Ted -- Zuijdgeest, David -- Khayat, Reza -- Ekiert, Damian C -- Lee, Jeong Hyun -- Metlagel, Zoltan -- Bujny, Miriam V -- Jongeneelen, Mandy -- van der Vlugt, Remko -- Lamrani, Mohammed -- Korse, Hans J W M -- Geelen, Eric -- Sahin, Ozcan -- Sieuwerts, Martijn -- Brakenhoff, Just P J -- Vogels, Ronald -- Li, Olive T W -- Poon, Leo L M -- Peiris, Malik -- Koudstaal, Wouter -- Ward, Andrew B -- Wilson, Ian A -- Goudsmit, Jaap -- Friesen, Robert H E -- GM080209/GM/NIGMS NIH HHS/ -- P41RR001209/RR/NCRR NIH HHS/ -- RR017573/RR/NCRR NIH HHS/ -- T32 GM080209/GM/NIGMS NIH HHS/ -- U54 GM094586/GM/NIGMS NIH HHS/ -- Y1-CO-1020/CO/NCI NIH HHS/ -- Y1-GM-1104/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2012 Sep 14;337(6100):1343-8. doi: 10.1126/science.1222908.

    Description: Impairment of the circadian clock has been associated with numerous disorders, including metabolic disease. Although small molecules that modulate clock function might offer therapeutic approaches to such diseases, only a few compounds have been identified that selectively target core clock proteins. From an unbiased cell-based circadian phenotypic screen, we identified KL001, a small molecule that specifically interacts with cryptochrome (CRY). KL001 prevented ubiquitin-dependent degradation of CRY, resulting in lengthening of the circadian period. In combination with mathematical modeling, our studies using KL001 revealed that CRY1 and CRY2 share a similar functional role in the period regulation. Furthermore, KL001-mediated CRY stabilization inhibited glucagon-induced gluconeogenesis in primary hepatocytes. KL001 thus provides a tool to study the regulation of CRY-dependent physiology and aid development of clock-based therapeutics of diabetes.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3589997/" 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/PMC3589997/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hirota, Tsuyoshi -- Lee, Jae Wook -- St John, Peter C -- Sawa, Mariko -- Iwaisako, Keiko -- Noguchi, Takako -- Pongsawakul, Pagkapol Y -- Sonntag, Tim -- Welsh, David K -- Brenner, David A -- Doyle, Francis J 3rd -- Schultz, Peter G -- Kay, Steve A -- GM074868/GM/NIGMS NIH HHS/ -- GM085764/GM/NIGMS NIH HHS/ -- GM096873/GM/NIGMS NIH HHS/ -- MH051573/MH/NIMH NIH HHS/ -- MH082945/MH/NIMH NIH HHS/ -- P50 GM085764/GM/NIGMS NIH HHS/ -- R01 GM041804/GM/NIGMS NIH HHS/ -- R01 GM074868/GM/NIGMS NIH HHS/ -- R01 GM096873/GM/NIGMS NIH HHS/ -- R01 MH051573/MH/NIMH NIH HHS/ -- R01 MH082945/MH/NIMH NIH HHS/ -- New York, N.Y. -- Science. 2012 Aug 31;337(6098):1094-7. doi: 10.1126/science.1223710.

    Description: Symbioses between nitrogen (N)(2)-fixing prokaryotes and photosynthetic eukaryotes are important for nitrogen acquisition in N-limited environments. Recently, a widely distributed planktonic uncultured nitrogen-fixing cyanobacterium (UCYN-A) was found to have unprecedented genome reduction, including the lack of oxygen-evolving photosystem II and the tricarboxylic acid cycle, which suggested partnership in a symbiosis. We showed that UCYN-A has a symbiotic association with a unicellular prymnesiophyte, closely related to calcifying taxa present in the fossil record. The partnership is mutualistic, because the prymnesiophyte receives fixed N in exchange for transferring fixed carbon to UCYN-A. This unusual partnership between a cyanobacterium and a unicellular alga is a model for symbiosis and is analogous to plastid and organismal evolution, and if calcifying, may have important implications for past and present oceanic N(2) fixation.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Thompson, Anne W -- Foster, Rachel A -- Krupke, Andreas -- Carter, Brandon J -- Musat, Niculina -- Vaulot, Daniel -- Kuypers, Marcel M M -- Zehr, Jonathan P -- New York, N.Y. -- Science. 2012 Sep 21;337(6101):1546-50.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Ocean Sciences, University of California, Santa Cruz, CA 95064, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/22997339" target="_blank"〉PubMed〈/a〉
