    Cyanophora paradoxa genome elucidates origin of photosynthesis in algae and plants (2012)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2012-02-22
    Description: The primary endosymbiotic origin of the plastid in eukaryotes more than 1 billion years ago led to the evolution of algae and plants. We analyzed draft genome and transcriptome data from the basally diverging alga Cyanophora paradoxa and provide evidence for a single origin of the primary plastid in the eukaryote supergroup Plantae. C. paradoxa retains ancestral features of starch biosynthesis, fermentation, and plastid protein translocation common to plants and algae but lacks typical eukaryotic light-harvesting complex proteins. Traces of an ancient link to parasites such as Chlamydiae were found in the genomes of C. paradoxa and other Plantae. Apparently, Chlamydia-like bacteria donated genes that allow export of photosynthate from the plastid and its polymerization into storage polysaccharide in the cytosol.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Price, Dana C -- Chan, Cheong Xin -- Yoon, Hwan Su -- Yang, Eun Chan -- Qiu, Huan -- Weber, Andreas P M -- Schwacke, Rainer -- Gross, Jeferson -- Blouin, Nicolas A -- Lane, Chris -- Reyes-Prieto, Adrian -- Durnford, Dion G -- Neilson, Jonathan A D -- Lang, B Franz -- Burger, Gertraud -- Steiner, Jurgen M -- Loffelhardt, Wolfgang -- Meuser, Jonathan E -- Posewitz, Matthew C -- Ball, Steven -- Arias, Maria Cecilia -- Henrissat, Bernard -- Coutinho, Pedro M -- Rensing, Stefan A -- Symeonidi, Aikaterini -- Doddapaneni, Harshavardhan -- Green, Beverley R -- Rajah, Veeran D -- Boore, Jeffrey -- Bhattacharya, Debashish -- MSP-14226/Canadian Institutes of Health Research/Canada -- New York, N.Y. -- Science. 2012 Feb 17;335(6070):843-7. doi: 10.1126/science.1213561.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Ecology, Evolution, and Natural Resources, Rutgers University, New Brunswick, NJ 08901, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/22344442" target="_blank"〉PubMed〈/a〉

    Natively inhibited Trypanosoma brucei cathepsin B structure determined by using an X-ray laser (2012)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2012-12-01
    Description: The Trypanosoma brucei cysteine protease cathepsin B (TbCatB), which is involved in host protein degradation, is a promising target to develop new treatments against sleeping sickness, a fatal disease caused by this protozoan parasite. The structure of the mature, active form of TbCatB has so far not provided sufficient information for the design of a safe and specific drug against T. brucei. By combining two recent innovations, in vivo crystallization and serial femtosecond crystallography, we obtained the room-temperature 2.1 angstrom resolution structure of the fully glycosylated precursor complex of TbCatB. The structure reveals the mechanism of native TbCatB inhibition and demonstrates that new biomolecular information can be obtained by the "diffraction-before-destruction" approach of x-ray free-electron lasers from hundreds of thousands of individual microcrystals.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3786669/" 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/PMC3786669/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Redecke, Lars -- Nass, Karol -- DePonte, Daniel P -- White, Thomas A -- Rehders, Dirk -- Barty, Anton -- Stellato, Francesco -- Liang, Mengning -- Barends, Thomas R M -- Boutet, Sebastien -- Williams, Garth J -- Messerschmidt, Marc -- Seibert, M Marvin -- Aquila, Andrew -- Arnlund, David -- Bajt, Sasa -- Barth, Torsten -- Bogan, Michael J -- Caleman, Carl -- Chao, Tzu-Chiao -- Doak, R Bruce -- Fleckenstein, Holger -- Frank, Matthias -- Fromme, Raimund -- Galli, Lorenzo -- Grotjohann, Ingo -- Hunter, Mark S -- Johansson, Linda C -- Kassemeyer, Stephan -- Katona, Gergely -- Kirian, Richard A -- Koopmann, Rudolf -- Kupitz, Chris -- Lomb, Lukas -- Martin, Andrew V -- Mogk, Stefan -- Neutze, Richard -- Shoeman, Robert L -- Steinbrener, Jan -- Timneanu, Nicusor -- Wang, Dingjie -- Weierstall, Uwe -- Zatsepin, Nadia A -- Spence, John C H -- Fromme, Petra -- Schlichting, Ilme -- Duszenko, Michael -- Betzel, Christian -- Chapman, Henry N -- 1R01GM095583/GM/NIGMS NIH HHS/ -- R01 GM095583/GM/NIGMS NIH HHS/ -- U54 GM094599/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2013 Jan 11;339(6116):227-30. doi: 10.1126/science.1229663.

    Airborne transmission of influenza A/H5N1 virus between ferrets (2012)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2012-06-23
    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〉

    Synchronizing nuclear import of ribosomal proteins with ribosome assembly (2012)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2012-11-03
    Description: Ribosomal proteins are synthesized in the cytoplasm, before nuclear import and assembly with ribosomal RNA (rRNA). Little is known about coordination of nucleocytoplasmic transport with ribosome assembly. Here, we identify a transport adaptor, symportin 1 (Syo1), that facilitates synchronized coimport of the two 5S-rRNA binding proteins Rpl5 and Rpl11. In vitro studies revealed that Syo1 concomitantly binds Rpl5-Rpl11 and furthermore recruits the import receptor Kap104. The Syo1-Rpl5-Rpl11 import complex is released from Kap104 by RanGTP and can be directly transferred onto the 5S rRNA. Syo1 can shuttle back to the cytoplasm by interaction with phenylalanine-glycine nucleoporins. X-ray crystallography uncovered how the alpha-solenoid symportin accommodates the Rpl5 amino terminus, normally bound to 5S rRNA, in an extended groove. Symportin-mediated coimport of Rpl5-Rpl11 could ensure coordinated and stoichiometric incorporation of these proteins into pre-60S ribosomes.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kressler, Dieter -- Bange, Gert -- Ogawa, Yutaka -- Stjepanovic, Goran -- Bradatsch, Bettina -- Pratte, Dagmar -- Amlacher, Stefan -- Strauss, Daniela -- Yoneda, Yoshihiro -- Katahira, Jun -- Sinning, Irmgard -- Hurt, Ed -- New York, N.Y. -- Science. 2012 Nov 2;338(6107):666-71. doi: 10.1126/science.1226960.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Biochemie-Zentrum der Universitat Heidelberg, Im Neuenheimer Feld 328, Heidelberg D-69120, Germany. dieter.kressler@unifr.ch〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/23118189" target="_blank"〉PubMed〈/a〉

    Ancestral developmental potential facilitates parallel evolution in ants (2012)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2012-01-10
    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〉

    Highly conserved protective epitopes on influenza B viruses (2012)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2012-08-11
    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.

    Identification of small molecule activators of cryptochrome (2012)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2012-07-17
    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.

    A DOC2 protein identified by mutational profiling is essential for apicomplexan parasite exocytosis (2012)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2012-01-17
    Description: Exocytosis is essential to the lytic cycle of apicomplexan parasites and required for the pathogenesis of toxoplasmosis and malaria. DOC2 proteins recruit the membrane fusion machinery required for exocytosis in a Ca(2+)-dependent fashion. Here, the phenotype of a Toxoplasma gondii conditional mutant impaired in host cell invasion and egress was pinpointed to a defect in secretion of the micronemes, an apicomplexan-specific organelle that contains adhesion proteins. Whole-genome sequencing identified the etiological point mutation in TgDOC2.1. A conditional allele of the orthologous gene engineered into Plasmodium falciparum was also defective in microneme secretion. However, the major effect was on invasion, suggesting that microneme secretion is dispensable for Plasmodium egress.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3354045/" 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/PMC3354045/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Farrell, Andrew -- Thirugnanam, Sivasakthivel -- Lorestani, Alexander -- Dvorin, Jeffrey D -- Eidell, Keith P -- Ferguson, David J P -- Anderson-White, Brooke R -- Duraisingh, Manoj T -- Marth, Gabor T -- Gubbels, Marc-Jan -- AI057919/AI/NIAID NIH HHS/ -- AI081220/AI/NIAID NIH HHS/ -- AI087874/AI/NIAID NIH HHS/ -- AI088314/AI/NIAID NIH HHS/ -- HG004719/HG/NHGRI NIH HHS/ -- K08 AI087874/AI/NIAID NIH HHS/ -- K08 AI087874-02/AI/NIAID NIH HHS/ -- R01 AI057919/AI/NIAID NIH HHS/ -- R01 HG004719/HG/NHGRI NIH HHS/ -- R21 AI081220/AI/NIAID NIH HHS/ -- R21 AI088314/AI/NIAID NIH HHS/ -- Wellcome Trust/United Kingdom -- New York, N.Y. -- Science. 2012 Jan 13;335(6065):218-21. doi: 10.1126/science.1210829.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biology, Boston College, Chestnut Hill, MA 02467, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/22246776" target="_blank"〉PubMed〈/a〉

Gene silencing showed that genes in a 31-kilobase segment at rhg1-b, encoding an amino acid transporter, an alpha-SNAP protein, and a WI12 (wound-inducible domain) protein, each contribute to resistance. There is one copy of the 31-kilobase segment per haploid genome in susceptible varieties, but 10 tandem copies are present in an rhg1-b haplotype. Overexpression of the individual genes in roots was ineffective, but overexpression of the genes together conferred enhanced SCN resistance. Hence, SCN resistance mediated by the soybean quantitative trait locus Rhg1 is conferred by copy number variation that increases the expression of a set of dissimilar genes in a repeated multigene segment.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Cook, David E -- Lee, Tong Geon -- Guo, Xiaoli -- Melito, Sara -- Wang, Kai -- Bayless, Adam M -- Wang, Jianping -- Hughes, Teresa J -- Willis, David K -- Clemente, Thomas E -- Diers, Brian W -- Jiang, Jiming -- Hudson, Matthew E -- Bent, Andrew F -- New York, N.Y. -- Science. 2012 Nov 30;338(6111):1206-9. doi: 10.1126/science.1228746.

    Description: Innate immune responses are vital for pathogen defense but can result in septic shock when excessive. A key mediator of septic shock is tumor necrosis factor-alpha (TNFalpha), which is shed from the plasma membrane after cleavage by the TNFalpha convertase (TACE). We report that the rhomboid family member iRhom2 interacted with TACE and regulated TNFalpha shedding. iRhom2 was critical for TACE maturation and trafficking to the cell surface in hematopoietic cells. Gene-targeted iRhom2-deficient mice showed reduced serum TNFalpha in response to lipopolysaccharide (LPS) and could survive a lethal LPS dose. Furthermore, iRhom2-deficient mice failed to control the replication of Listeria monocytogenes. Our study has identified iRhom2 as a regulator of innate immunity that may be an important target for modulating sepsis and pathogen defense.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4250273/" 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/PMC4250273/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉McIlwain, David R -- Lang, Philipp A -- Maretzky, Thorsten -- Hamada, Koichi -- Ohishi, Kazuhito -- Maney, Sathish Kumar -- Berger, Thorsten -- Murthy, Aditya -- Duncan, Gordon -- Xu, Haifeng C -- Lang, Karl S -- Haussinger, Dieter -- Wakeham, Andrew -- Itie-Youten, Annick -- Khokha, Rama -- Ohashi, Pamela S -- Blobel, Carl P -- Mak, Tak W -- GM64750/GM/NIGMS NIH HHS/ -- R01 GM064750/GM/NIGMS NIH HHS/ -- Canadian Institutes of Health Research/Canada -- New York, N.Y. -- Science. 2012 Jan 13;335(6065):229-32. doi: 10.1126/science.1214448.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Campell Family Institute for Breast Cancer Research, Ontario Cancer Institute, University Health Network (UHN), 620 University Avenue, Toronto, Ontario M5G 2C1, Canada.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/22246778" target="_blank"〉PubMed〈/a〉
