    Description: We report a draft sequence for the genome of the domesticated silkworm (Bombyx mori), covering 90.9% of all known silkworm genes. Our estimated gene count is 18,510, which exceeds the 13,379 genes reported for Drosophila melanogaster. Comparative analyses to fruitfly, mosquito, spider, and butterfly reveal both similarities and differences in gene content.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Xia, Qingyou -- Zhou, Zeyang -- Lu, Cheng -- Cheng, Daojun -- Dai, Fangyin -- Li, Bin -- Zhao, Ping -- Zha, Xingfu -- Cheng, Tingcai -- Chai, Chunli -- Pan, Guoqing -- Xu, Jinshan -- Liu, Chun -- Lin, Ying -- Qian, Jifeng -- Hou, Yong -- Wu, Zhengli -- Li, Guanrong -- Pan, Minhui -- Li, Chunfeng -- Shen, Yihong -- Lan, Xiqian -- Yuan, Lianwei -- Li, Tian -- Xu, Hanfu -- Yang, Guangwei -- Wan, Yongji -- Zhu, Yong -- Yu, Maode -- Shen, Weide -- Wu, Dayang -- Xiang, Zhonghuai -- Yu, Jun -- Wang, Jun -- Li, Ruiqiang -- Shi, Jianping -- Li, Heng -- Li, Guangyuan -- Su, Jianning -- Wang, Xiaoling -- Li, Guoqing -- Zhang, Zengjin -- Wu, Qingfa -- Li, Jun -- Zhang, Qingpeng -- Wei, Ning -- Xu, Jianzhe -- Sun, Haibo -- Dong, Le -- Liu, Dongyuan -- Zhao, Shengli -- Zhao, Xiaolan -- Meng, Qingshun -- Lan, Fengdi -- Huang, Xiangang -- Li, Yuanzhe -- Fang, Lin -- Li, Changfeng -- Li, Dawei -- Sun, Yongqiao -- Zhang, Zhenpeng -- Yang, Zheng -- Huang, Yanqing -- Xi, Yan -- Qi, Qiuhui -- He, Dandan -- Huang, Haiyan -- Zhang, Xiaowei -- Wang, Zhiqiang -- Li, Wenjie -- Cao, Yuzhu -- Yu, Yingpu -- Yu, Hong -- Li, Jinhong -- Ye, Jiehua -- Chen, Huan -- Zhou, Yan -- Liu, Bin -- Wang, Jing -- Ye, Jia -- Ji, Hai -- Li, Shengting -- Ni, Peixiang -- Zhang, Jianguo -- Zhang, Yong -- Zheng, Hongkun -- Mao, Bingyu -- Wang, Wen -- Ye, Chen -- Li, Songgang -- Wang, Jian -- Wong, Gane Ka-Shu -- Yang, Huanming -- Biology Analysis Group -- 1 P50 HG02351/HG/NHGRI NIH HHS/ -- New York, N.Y. -- Science. 2004 Dec 10;306(5703):1937-40.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Southwest Agricultural University, Chongqing Beibei, 400716, China. xiaqy@swau.cq.cn〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/15591204" target="_blank"〉PubMed〈/a〉

    Description: Diatoms are unicellular algae with plastids acquired by secondary endosymbiosis. They are responsible for approximately 20% of global carbon fixation. We report the 34 million-base pair draft nuclear genome of the marine diatom Thalassiosira pseudonana and its 129 thousand-base pair plastid and 44 thousand-base pair mitochondrial genomes. Sequence and optical restriction mapping revealed 24 diploid nuclear chromosomes. We identified novel genes for silicic acid transport and formation of silica-based cell walls, high-affinity iron uptake, biosynthetic enzymes for several types of polyunsaturated fatty acids, use of a range of nitrogenous compounds, and a complete urea cycle, all attributes that allow diatoms to prosper in aquatic environments.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Armbrust, E Virginia -- Berges, John A -- Bowler, Chris -- Green, Beverley R -- Martinez, Diego -- Putnam, Nicholas H -- Zhou, Shiguo -- Allen, Andrew E -- Apt, Kirk E -- Bechner, Michael -- Brzezinski, Mark A -- Chaal, Balbir K -- Chiovitti, Anthony -- Davis, Aubrey K -- Demarest, Mark S -- Detter, J Chris -- Glavina, Tijana -- Goodstein, David -- Hadi, Masood Z -- Hellsten, Uffe -- Hildebrand, Mark -- Jenkins, Bethany D -- Jurka, Jerzy -- Kapitonov, Vladimir V -- Kroger, Nils -- Lau, Winnie W Y -- Lane, Todd W -- Larimer, Frank W -- Lippmeier, J Casey -- Lucas, Susan -- Medina, Monica -- Montsant, Anton -- Obornik, Miroslav -- Parker, Micaela Schnitzler -- Palenik, Brian -- Pazour, Gregory J -- Richardson, Paul M -- Rynearson, Tatiana A -- Saito, Mak A -- Schwartz, David C -- Thamatrakoln, Kimberlee -- Valentin, Klaus -- Vardi, Assaf -- Wilkerson, Frances P -- Rokhsar, Daniel S -- New York, N.Y. -- Science. 2004 Oct 1;306(5693):79-86.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉School of Oceanography, University of Washington, Seattle, WA 98195, USA. armbrust@ocean.washington.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/15459382" target="_blank"〉PubMed〈/a〉

    Description: The life cycles of sexually reproducing animals and flowering plants begin with male and female gametes and their fusion to form a zygote. Selection at this earliest stage is crucial for offspring quality and raises similar evolutionary issues, yet zoology and botany use dissimilar approaches. There are striking parallels in the role of prezygotic competition for sexual selection on males, cryptic female choice, sexual conflict, and against selfish genetic elements and genetic incompatibility. In both groups, understanding the evolution of sex-specific and reproductive traits will require an appreciation of the effects of prezygotic competition on fitness.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bernasconi, G -- Ashman, T-L -- Birkhead, T R -- Bishop, J D D -- Grossniklaus, U -- Kubli, E -- Marshall, D L -- Schmid, B -- Skogsmyr, I -- Snook, R R -- Taylor, D -- Till-Bottraud, I -- Ward, P I -- Zeh, D W -- Hellriegel, B -- New York, N.Y. -- Science. 2004 Feb 13;303(5660):971-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Institute of Environmental Sciences, University of Zurich, Winterthurerstrasse 190, CH-8057 Zurich, Switzerland. bernasco@uwinst.unizh.ch〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/14963320" target="_blank"〉PubMed〈/a〉

    Description: To initiate studies on how protein-protein interaction (or "interactome") networks relate to multicellular functions, we have mapped a large fraction of the Caenorhabditis elegans interactome network. Starting with a subset of metazoan-specific proteins, more than 4000 interactions were identified from high-throughput, yeast two-hybrid (HT=Y2H) screens. Independent coaffinity purification assays experimentally validated the overall quality of this Y2H data set. Together with already described Y2H interactions and interologs predicted in silico, the current version of the Worm Interactome (WI5) map contains approximately 5500 interactions. Topological and biological features of this interactome network, as well as its integration with phenome and transcriptome data sets, lead to numerous biological hypotheses.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC1698949/" 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/PMC1698949/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Li, Siming -- Armstrong, Christopher M -- Bertin, Nicolas -- Ge, Hui -- Milstein, Stuart -- Boxem, Mike -- Vidalain, Pierre-Olivier -- Han, Jing-Dong J -- Chesneau, Alban -- Hao, Tong -- Goldberg, Debra S -- Li, Ning -- Martinez, Monica -- Rual, Jean-Francois -- Lamesch, Philippe -- Xu, Lai -- Tewari, Muneesh -- Wong, Sharyl L -- Zhang, Lan V -- Berriz, Gabriel F -- Jacotot, Laurent -- Vaglio, Philippe -- Reboul, Jerome -- Hirozane-Kishikawa, Tomoko -- Li, Qianru -- Gabel, Harrison W -- Elewa, Ahmed -- Baumgartner, Bridget -- Rose, Debra J -- Yu, Haiyuan -- Bosak, Stephanie -- Sequerra, Reynaldo -- Fraser, Andrew -- Mango, Susan E -- Saxton, William M -- Strome, Susan -- Van Den Heuvel, Sander -- Piano, Fabio -- Vandenhaute, Jean -- Sardet, Claude -- Gerstein, Mark -- Doucette-Stamm, Lynn -- Gunsalus, Kristin C -- Harper, J Wade -- Cusick, Michael E -- Roth, Frederick P -- Hill, David E -- Vidal, Marc -- R01 AG011085/AG/NIA NIH HHS/ -- R01 GM034059/GM/NIGMS NIH HHS/ -- R01 GM034059-18/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2004 Jan 23;303(5657):540-3.

    Description: We describe the efficacy of L-870812, an inhibitor of HIV-1 and SIV integrase, in rhesus macaques infected with the simian-human immunodeficiency virus (SHIV) 89.6P. When initiated before CD4 cell depletion, L-870812 therapy mediated a sustained suppression of viremia, preserving CD4 levels and permitting the induction of virus-specific cellular immunity. L-870812 was also active in chronic infection; however, the magnitude and durability of the effect varied in conjunction with the pretreatment immune response and viral load. These studies demonstrate integrase inhibitor activity in vivo and suggest that cellular immunity facilitates chemotherapeutic efficacy in retroviral infections.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hazuda, Daria J -- Young, Steven D -- Guare, James P -- Anthony, Neville J -- Gomez, Robert P -- Wai, John S -- Vacca, Joseph P -- Handt, Larry -- Motzel, Sherri L -- Klein, Hilton J -- Dornadula, Geethanjali -- Danovich, Robert M -- Witmer, Marc V -- Wilson, Keith A A -- Tussey, Lynda -- Schleif, William A -- Gabryelski, Lori S -- Jin, Lixia -- Miller, Michael D -- Casimiro, Danilo R -- Emini, Emilio A -- Shiver, John W -- New York, N.Y. -- Science. 2004 Jul 23;305(5683):528-32.

    Description: The 1918 influenza pandemic resulted in about 20 million deaths. This enormous impact, coupled with renewed interest in emerging infections, makes characterization of the virus involved a priority. Receptor binding, the initial event in virus infection, is a major determinant of virus transmissibility that, for influenza viruses, is mediated by the hemagglutinin (HA) membrane glycoprotein. We have determined the crystal structures of the HA from the 1918 virus and two closely related HAs in complex with receptor analogs. They explain how the 1918 HA, while retaining receptor binding site amino acids characteristic of an avian precursor HA, is able to bind human receptors and how, as a consequence, the virus was able to spread in the human population.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gamblin, S J -- Haire, L F -- Russell, R J -- Stevens, D J -- Xiao, B -- Ha, Y -- Vasisht, N -- Steinhauer, D A -- Daniels, R S -- Elliot, A -- Wiley, D C -- Skehel, J J -- AI-13654/AI/NIAID NIH HHS/ -- New York, N.Y. -- Science. 2004 Mar 19;303(5665):1838-42.

    Description: In the developing brain, transcription factors (TFs) direct the formation of a diverse array of neurons and glia. We identifed 1445 putative TFs in the mouse genome. We used in situ hybridization to map the expression of over 1000 of these TFs and TF-coregulator genes in the brains of developing mice. We found that 349 of these genes showed restricted expression patterns that were adequate to describe the anatomical organization of the brain. We provide a comprehensive inventory of murine TFs and their expression patterns in a searchable brain atlas database.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gray, Paul A -- Fu, Hui -- Luo, Ping -- Zhao, Qing -- Yu, Jing -- Ferrari, Annette -- Tenzen, Toyoaki -- Yuk, Dong-In -- Tsung, Eric F -- Cai, Zhaohui -- Alberta, John A -- Cheng, Le-Ping -- Liu, Yang -- Stenman, Jan M -- Valerius, M Todd -- Billings, Nathan -- Kim, Haesun A -- Greenberg, Michael E -- McMahon, Andrew P -- Rowitch, David H -- Stiles, Charles D -- Ma, Qiufu -- New York, N.Y. -- Science. 2004 Dec 24;306(5705):2255-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Neurobiology, Harvard Medical School, Boston, MA 02115, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/15618518" target="_blank"〉PubMed〈/a〉

    Description: The structure of an RNA polymerase II-transcribing complex has been determined in the posttranslocation state, with a vacancy at the growing end of the RNA-DNA hybrid helix. At the opposite end of the hybrid helix, the RNA separates from the template DNA. This separation of nucleic acid strands is brought about by interaction with a set of proteins loops in a strand/loop network. Formation of the network must occur in the transition from abortive initiation to promoter escape.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Westover, Kenneth D -- Bushnell, David A -- Kornberg, Roger D -- GM49985/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2004 Feb 13;303(5660):1014-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Structural Biology, Stanford University School of Medicine, Stanford, CA 94305-5126, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/14963331" target="_blank"〉PubMed〈/a〉

    Description: Unlike major histocompatibility proteins, which bind peptides, CD1 proteins display lipid antigens to T cells. Here, we report that CD1a presents a family of previously unknown lipopeptides from Mycobacterium tuberculosis, named didehydroxymycobactins because of their structural relation to mycobactin siderophores. T cell activation was mediated by the alphabeta T cell receptors and was specific for structure of the acyl and peptidic components of these antigens. These studies identify a means of intracellular pathogen detection and identify lipopeptides as a biochemical class of antigens for T cells, which, like conventional peptides, have a potential for marked structural diversity.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Moody, D Branch -- Young, David C -- Cheng, Tan-Yun -- Rosat, Jean-Pierre -- Roura-Mir, Carme -- O'Connor, Peter B -- Zajonc, Dirk M -- Walz, Andrew -- Miller, Marvin J -- Levery, Steven B -- Wilson, Ian A -- Costello, Catherine E -- Brenner, Michael B -- AI30988/AI/NIAID NIH HHS/ -- AI50216/AI/NIAID NIH HHS/ -- AR48632/AR/NIAMS NIH HHS/ -- CA58896/CA/NCI NIH HHS/ -- GM25845/GM/NIGMS NIH HHS/ -- GM62116/GM/NIGMS NIH HHS/ -- P20 RR16459/RR/NCRR NIH HHS/ -- P41-RR10888/RR/NCRR NIH HHS/ -- S10-RR10493/RR/NCRR NIH HHS/ -- New York, N.Y. -- Science. 2004 Jan 23;303(5657):527-31.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Division of Rheumatology, Immunology and Allergy, Brigham and Women's Hospital and Harvard Medical School, Smith Building Room 514, 1 Jimmy Fund Way, Boston, MA 02115, USA. bmoody@rics.bwh.harvard.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/14739458" target="_blank"〉PubMed〈/a〉
