    Description: A novel coronavirus (SCoV) is the etiological agent of severe acute respiratory syndrome (SARS). SCoV-like viruses were isolated from Himalayan palm civets found in a live-animal market in Guangdong, China. Evidence of virus infection was also detected in other animals (including a raccoon dog, Nyctereutes procyonoides) and in humans working at the same market. All the animal isolates retain a 29-nucleotide sequence that is not found in most human isolates. The detection of SCoV-like viruses in small, live wild mammals in a retail market indicates a route of interspecies transmission, although the natural reservoir is not known.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Guan, Y -- Zheng, B J -- He, Y Q -- Liu, X L -- Zhuang, Z X -- Cheung, C L -- Luo, S W -- Li, P H -- Zhang, L J -- Guan, Y J -- Butt, K M -- Wong, K L -- Chan, K W -- Lim, W -- Shortridge, K F -- Yuen, K Y -- Peiris, J S M -- Poon, L L M -- New York, N.Y. -- Science. 2003 Oct 10;302(5643):276-8.

    Description: DNA sequence and annotation of the entire human chromosome 7, encompassing nearly 158 million nucleotides of DNA and 1917 gene structures, are presented. To generate a higher order description, additional structural features such as imprinted genes, fragile sites, and segmental duplications were integrated at the level of the DNA sequence with medical genetic data, including 440 chromosome rearrangement breakpoints associated with disease. This approach enabled the discovery of candidate genes for developmental diseases including autism.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2882961/" 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/PMC2882961/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Scherer, Stephen W -- Cheung, Joseph -- MacDonald, Jeffrey R -- Osborne, Lucy R -- Nakabayashi, Kazuhiko -- Herbrick, Jo-Anne -- Carson, Andrew R -- Parker-Katiraee, Layla -- Skaug, Jennifer -- Khaja, Razi -- Zhang, Junjun -- Hudek, Alexander K -- Li, Martin -- Haddad, May -- Duggan, Gavin E -- Fernandez, Bridget A -- Kanematsu, Emiko -- Gentles, Simone -- Christopoulos, Constantine C -- Choufani, Sanaa -- Kwasnicka, Dorota -- Zheng, Xiangqun H -- Lai, Zhongwu -- Nusskern, Deborah -- Zhang, Qing -- Gu, Zhiping -- Lu, Fu -- Zeesman, Susan -- Nowaczyk, Malgorzata J -- Teshima, Ikuko -- Chitayat, David -- Shuman, Cheryl -- Weksberg, Rosanna -- Zackai, Elaine H -- Grebe, Theresa A -- Cox, Sarah R -- Kirkpatrick, Susan J -- Rahman, Nazneen -- Friedman, Jan M -- Heng, Henry H Q -- Pelicci, Pier Giuseppe -- Lo-Coco, Francesco -- Belloni, Elena -- Shaffer, Lisa G -- Pober, Barbara -- Morton, Cynthia C -- Gusella, James F -- Bruns, Gail A P -- Korf, Bruce R -- Quade, Bradley J -- Ligon, Azra H -- Ferguson, Heather -- Higgins, Anne W -- Leach, Natalia T -- Herrick, Steven R -- Lemyre, Emmanuelle -- Farra, Chantal G -- Kim, Hyung-Goo -- Summers, Anne M -- Gripp, Karen W -- Roberts, Wendy -- Szatmari, Peter -- Winsor, Elizabeth J T -- Grzeschik, Karl-Heinz -- Teebi, Ahmed -- Minassian, Berge A -- Kere, Juha -- Armengol, Lluis -- Pujana, Miguel Angel -- Estivill, Xavier -- Wilson, Michael D -- Koop, Ben F -- Tosi, Sabrina -- Moore, Gudrun E -- Boright, Andrew P -- Zlotorynski, Eitan -- Kerem, Batsheva -- Kroisel, Peter M -- Petek, Erwin -- Oscier, David G -- Mould, Sarah J -- Dohner, Hartmut -- Dohner, Konstanze -- Rommens, Johanna M -- Vincent, John B -- Venter, J Craig -- Li, Peter W -- Mural, Richard J -- Adams, Mark D -- Tsui, Lap-Chee -- 38103/Canadian Institutes of Health Research/Canada -- P01 GM061354/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2003 May 2;300(5620):767-72.

    Description: In March 2003, a novel coronavirus (SARS-CoV) was discovered in association with cases of severe acute respiratory syndrome (SARS). The sequence of the complete genome of SARS-CoV was determined, and the initial characterization of the viral genome is presented in this report. The genome of SARS-CoV is 29,727 nucleotides in length and has 11 open reading frames, and its genome organization is similar to that of other coronaviruses. Phylogenetic analyses and sequence comparisons showed that SARS-CoV is not closely related to any of the previously characterized coronaviruses.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Rota, Paul A -- Oberste, M Steven -- Monroe, Stephan S -- Nix, W Allan -- Campagnoli, Ray -- Icenogle, Joseph P -- Penaranda, Silvia -- Bankamp, Bettina -- Maher, Kaija -- Chen, Min-Hsin -- Tong, Suxiong -- Tamin, Azaibi -- Lowe, Luis -- Frace, Michael -- DeRisi, Joseph L -- Chen, Qi -- Wang, David -- Erdman, Dean D -- Peret, Teresa C T -- Burns, Cara -- Ksiazek, Thomas G -- Rollin, Pierre E -- Sanchez, Anthony -- Liffick, Stephanie -- Holloway, Brian -- Limor, Josef -- McCaustland, Karen -- Olsen-Rasmussen, Melissa -- Fouchier, Ron -- Gunther, Stephan -- Osterhaus, Albert D M E -- Drosten, Christian -- Pallansch, Mark A -- Anderson, Larry J -- Bellini, William J -- New York, N.Y. -- Science. 2003 May 30;300(5624):1394-9.

    Description: We report the design and total chemical synthesis of "synthetic erythropoiesis protein" (SEP), a 51-kilodalton protein-polymer construct consisting of a 166-amino-acid polypeptide chain and two covalently attached, branched, and monodisperse polymer moieties that are negatively charged. The ability to control the chemistry allowed us to synthesize a macromolecule of precisely defined covalent structure. SEP was homogeneous as shown by high-resolution analytical techniques, with a mass of 50,825 +/-10 daltons by electrospray mass spectrometry, and with a pI of 5.0. In cell and animal assays for erythropoiesis, SEP displayed potent biological activity and had significantly prolonged duration of action in vivo. These chemical methods are a powerful tool in the rational design of protein constructs with potential therapeutic applications.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kochendoerfer, Gerd G -- Chen, Shiah-Yun -- Mao, Feng -- Cressman, Sonya -- Traviglia, Stacey -- Shao, Haiyan -- Hunter, Christie L -- Low, Donald W -- Cagle, E Neil -- Carnevali, Maia -- Gueriguian, Vincent -- Keogh, Peter J -- Porter, Heather -- Stratton, Stephen M -- Wiedeke, M Con -- Wilken, Jill -- Tang, Jie -- Levy, Jay J -- Miranda, Les P -- Crnogorac, Milan M -- Kalbag, Suresh -- Botti, Paolo -- Schindler-Horvat, Janice -- Savatski, Laura -- Adamson, John W -- Kung, Ada -- Kent, Stephen B H -- Bradburne, James A -- New York, N.Y. -- Science. 2003 Feb 7;299(5608):884-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Gryphon Therapeutics, 250 East Grand Avenue, Suite 90, South San Francisco, CA 94080, USA.

    Description: Approximately 80% of the maize genome comprises highly repetitive sequences interspersed with single-copy, gene-rich sequences, and standard genome sequencing strategies are not readily adaptable to this type of genome. Methodologies that enrich for genic sequences might more rapidly generate useful results from complex genomes. Equivalent numbers of clones from maize selected by techniques called methylation filtering and High C0t selection were sequenced to generate approximately 200,000 reads (approximately 132 megabases), which were assembled into contigs. Combination of the two techniques resulted in a sixfold reduction in the effective genome size and a fourfold increase in the gene identification rate in comparison to a nonenriched library.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Whitelaw, C A -- Barbazuk, W B -- Pertea, G -- Chan, A P -- Cheung, F -- Lee, Y -- Zheng, L -- van Heeringen, S -- Karamycheva, S -- Bennetzen, J L -- SanMiguel, P -- Lakey, N -- Bedell, J -- Yuan, Y -- Budiman, M A -- Resnick, A -- Van Aken, S -- Utterback, T -- Riedmuller, S -- Williams, M -- Feldblyum, T -- Schubert, K -- Beachy, R -- Fraser, C M -- Quackenbush, J -- New York, N.Y. -- Science. 2003 Dec 19;302(5653):2118-20.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉The Institute for Genomic Research (TIGR), 9712 Medical Center Drive, Rockville, MD 20850, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/14684821" target="_blank"〉PubMed〈/a〉

    Description: A survey of the dog genome sequence (6.22 million sequence reads; 1.5x coverage) demonstrates the power of sample sequencing for comparative analysis of mammalian genomes and the generation of species-specific resources. More than 650 million base pairs (〉25%) of dog sequence align uniquely to the human genome, including fragments of putative orthologs for 18,473 of 24,567 annotated human genes. Mutation rates, conserved synteny, repeat content, and phylogeny can be compared among human, mouse, and dog. A variety of polymorphic elements are identified that will be valuable for mapping the genetic basis of diseases and traits in the dog.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kirkness, Ewen F -- Bafna, Vineet -- Halpern, Aaron L -- Levy, Samuel -- Remington, Karin -- Rusch, Douglas B -- Delcher, Arthur L -- Pop, Mihai -- Wang, Wei -- Fraser, Claire M -- Venter, J Craig -- New York, N.Y. -- Science. 2003 Sep 26;301(5641):1898-903.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉The Institute for Genomic Research, Rockville, MD 20850, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/14512627" target="_blank"〉PubMed〈/a〉

    Description: Vancomycin is usually reserved for treatment of serious infections, including those caused by multidrug-resistant Staphylococcus aureus. A clinical isolate of S. aureus with high-level resistance to vancomycin (minimal inhibitory concentration = 1024 microg/ml) was isolated in June 2002. This isolate harbored a 57.9-kilobase multiresistance conjugative plasmid within which Tn1546 (vanA) was integrated. Additional elements on the plasmid encoded resistance to trimethoprim (dfrA), beta-lactams (blaZ), aminoglycosides (aacA-aphD), and disinfectants (qacC). Genetic analyses suggest that the long-anticipated transfer of vancomycin resistance to a methicillin-resistant S. aureus occurred in vivo by interspecies transfer of Tn1546 from a co-isolate of Enterococcus faecalis.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Weigel, Linda M -- Clewell, Don B -- Gill, Steven R -- Clark, Nancye C -- McDougal, Linda K -- Flannagan, Susan E -- Kolonay, James F -- Shetty, Jyoti -- Killgore, George E -- Tenover, Fred C -- N01-AI-95359/AI/NIAID NIH HHS/ -- New York, N.Y. -- Science. 2003 Nov 28;302(5650):1569-71.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Division of Healthcare Quality Promotion, Centers for Disease Control and Prevention, Atlanta, GA 30333, USA. lweigel@cdc.gov〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/14645850" target="_blank"〉PubMed〈/a〉

    Description: Activated CD8+ T cells play a critical role in host defense against viruses, intracellular microbes, and tumors. It is not clear if a key regulatory transcription factor unites the effector functions of CD8+ T cells. We now show that Eomesodermin (Eomes), a paralogue of T-bet, is induced in effector CD8+ T cells in vitro and in vivo. Ectopic expression of Eomes was sufficient to invoke attributes of effector CD8+ T cells, including interferon-gamma (IFN-gamma), perforin, and granzyme B. Loss-of-function analysis suggests Eomes may also be necessary for full effector differentiation of CD8+ T cells. We suggest that Eomesodermin is likely to complement the actions of T-bet and act as a key regulatory gene in the development of cell-mediated immunity.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Pearce, Erika L -- Mullen, Alan C -- Martins, Gislaine A -- Krawczyk, Connie M -- Hutchins, Anne S -- Zediak, Valerie P -- Banica, Monica -- DiCioccio, Catherine B -- Gross, Darrick A -- Mao, Chai-An -- Shen, Hao -- Cereb, Nezih -- Yang, Soo Y -- Lindsten, Tullia -- Rossant, Janet -- Hunter, Christopher A -- Reiner, Steven L -- AI-042370/AI/NIAID NIH HHS/ -- GM-07229/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2003 Nov 7;302(5647):1041-3.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Abramson Family Cancer Research Institute, and Department of Medicine, University of Pennsylvania, Philadelphia, PA 19104, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/14605368" target="_blank"〉PubMed〈/a〉

    Description: Phototropins are light-activated kinases important for plant responses to blue light. Light initiates signaling in these proteins by generating a covalent protein-flavin mononucleotide (FMN) adduct within sensory Per-ARNT-Sim (PAS) domains. We characterized the light-dependent changes of a phototropin PAS domain by solution nuclear magnetic resonance spectroscopy and found that an alpha helix located outside the canonical domain plays a key role in this activation process. Although this helix associates with the PAS core in the dark, photoinduced changes in the domain structure disrupt this interaction. We propose that this mechanism couples light-dependent bond formation to kinase activation and identifies a signaling pathway conserved among PAS domains.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Harper, Shannon M -- Neil, Lori C -- Gardner, Kevin H -- CA90601/CA/NCI NIH HHS/ -- GM08297/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2003 Sep 12;301(5639):1541-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Departments of Biochemistry and Pharmacology, University of Texas Southwestern Medical Center, 5323 Harry Hines Boulevard, Dallas, TX 75390-9038, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/12970567" target="_blank"〉PubMed〈/a〉

    Description: Human antibody 2G12 neutralizes a broad range of human immunodeficiency virus type 1 (HIV-1) isolates by binding an unusually dense cluster of carbohydrate moieties on the "silent" face of the gp120 envelope glycoprotein. Crystal structures of Fab 2G12 and its complexes with the disaccharide Manalpha1-2Man and with the oligosaccharide Man9GlcNAc2 revealed that two Fabs assemble into an interlocked VH domain-swapped dimer. Further biochemical, biophysical, and mutagenesis data strongly support a Fab-dimerized antibody as the prevalent form that recognizes gp120. The extraordinary configuration of this antibody provides an extended surface, with newly described binding sites, for multivalent interaction with a conserved cluster of oligomannose type sugars on the surface of gp120. The unique interdigitation of Fab domains within an antibody uncovers a previously unappreciated mechanism for high-affinity recognition of carbohydrate or other repeating epitopes on cell or microbial surfaces.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Calarese, Daniel A -- Scanlan, Christopher N -- Zwick, Michael B -- Deechongkit, Songpon -- Mimura, Yusuke -- Kunert, Renate -- Zhu, Ping -- Wormald, Mark R -- Stanfield, Robyn L -- Roux, Kenneth H -- Kelly, Jeffery W -- Rudd, Pauline M -- Dwek, Raymond A -- Katinger, Hermann -- Burton, Dennis R -- Wilson, Ian A -- AI33292/AI/NIAID NIH HHS/ -- GM46192/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2003 Jun 27;300(5628):2065-71.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Molecular Biology, The Scripps Research Institute, 10550 North Torrey Pines Road, La Jolla, CA 92037, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/12829775" target="_blank"〉PubMed〈/a〉
