    Arabidopsis transcription factors: genome-wide comparative analysis among eukaryotes (2000)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2000-12-16
    Description: The completion of the Arabidopsis thaliana genome sequence allows a comparative analysis of transcriptional regulators across the three eukaryotic kingdoms. Arabidopsis dedicates over 5% of its genome to code for more than 1500 transcription factors, about 45% of which are from families specific to plants. Arabidopsis transcription factors that belong to families common to all eukaryotes do not share significant similarity with those of the other kingdoms beyond the conserved DNA binding domains, many of which have been arranged in combinations specific to each lineage. The genome-wide comparison reveals the evolutionary generation of diversity in the regulation of transcription.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Riechmann, J L -- Heard, J -- Martin, G -- Reuber, L -- Jiang, C -- Keddie, J -- Adam, L -- Pineda, O -- Ratcliffe, O J -- Samaha, R R -- Creelman, R -- Pilgrim, M -- Broun, P -- Zhang, J Z -- Ghandehari, D -- Sherman, B K -- Yu, G -- New York, N.Y. -- Science. 2000 Dec 15;290(5499):2105-10.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Mendel Biotechnology, 21375 Cabot Boulevard, Hayward, CA 94545, USA. jriechmann@mendelbio.com〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/11118137" target="_blank"〉PubMed〈/a〉

    Sexual transmission and propagation of SIV and HIV in resting and activated CD4+ T cells (1999)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1999-11-13
    Description: In sexual transmission of simian immunodeficiency virus, and early and later stages of human immunodeficiency virus-type 1 (HIV-1) infection, both viruses were found to replicate predominantly in CD4(+) T cells at the portal of entry and in lymphoid tissues. Infection was propagated not only in activated and proliferating T cells but also, surprisingly, in resting T cells. The infected proliferating cells correspond to the short-lived population that produces the bulk of HIV-1. Most of the HIV-1-infected resting T cells persisted after antiretroviral therapy. Latently and chronically infected cells that may be derived from this population pose challenges to eradicating infection and developing an effective vaccine.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Zhang, Z -- Schuler, T -- Zupancic, M -- Wietgrefe, S -- Staskus, K A -- Reimann, K A -- Reinhart, T A -- Rogan, M -- Cavert, W -- Miller, C J -- Veazey, R S -- Notermans, D -- Little, S -- Danner, S A -- Richman, D D -- Havlir, D -- Wong, J -- Jordan, H L -- Schacker, T W -- Racz, P -- Tenner-Racz, K -- Letvin, N L -- Wolinsky, S -- Haase, A T -- AI 28246/AI/NIAID NIH HHS/ -- AI 38565/AI/NIAID NIH HHS/ -- RR 00168/RR/NCRR NIH HHS/ -- New York, N.Y. -- Science. 1999 Nov 12;286(5443):1353-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Microbiology, University of Minnesota Medical School, Minneapolis, MN 55455, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/10558989" target="_blank"〉PubMed〈/a〉

    Roles of PLC-beta2 and -beta3 and PI3Kgamma in chemoattractant-mediated signal transduction (2000)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2000-02-11
    Description: The roles of phosphoinositide 3-kinase (PI3K) and phospholipase C (PLC) in chemoattractant-elicited responses were studied in mice lacking these key enzymes. PI3Kgamma was required for chemoattractant-induced production of phosphatidylinositol 3,4,5-trisphosphate [PtdIns (3,4,5)P3] and has an important role in chemoattractant-induced superoxide production and chemotaxis in mouse neutrophils and in production of T cell-independent antigen-specific antibodies composed of the immunoglobulin lambda light chain (TI-IglambdaL). The study of the mice lacking PLC-beta2 and -beta3 revealed that the PLC pathways have an important role in chemoattractant-mediated production of superoxide and regulation of protein kinases, but not chemotaxis. The PLC pathways also appear to inhibit the chemotactic activity induced by certain chemoattractants and to suppress TI-IglambdaL production.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Li, Z -- Jiang, H -- Xie, W -- Zhang, Z -- Smrcka, A V -- Wu, D -- New York, N.Y. -- Science. 2000 Feb 11;287(5455):1046-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Pharmacology, University of Rochester, Rochester, NY 14642, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/10669417" target="_blank"〉PubMed〈/a〉

    Severe fibronectin-deposit renal glomerular disease in mice lacking uteroglobin (1997)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1997-05-30
    Description: Despite myriads of biological activities ascribed to uteroglobin (UG), a steroid-inducible secreted protein, its physiological functions are unknown. Mice in which the uteroglobin gene was disrupted had severe renal disease that was associated with massive glomerular deposition of predominantly multimeric fibronectin (Fn). The molecular mechanism that normally prevents Fn deposition appears to involve high-affinity binding of UG with Fn to form Fn-UG heteromers that counteract Fn self-aggregation, which is required for abnormal tissue deposition. Thus, UG is essential for maintaining normal renal function in mice, which raises the possibility that an analogous pathogenic mechanism may underlie genetic Fn-deposit human glomerular disease.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Zhang, Z -- Kundu, G C -- Yuan, C J -- Ward, J M -- Lee, E J -- DeMayo, F -- Westphal, H -- Mukherjee, A B -- HL47620/HL/NHLBI NIH HHS/ -- New York, N.Y. -- Science. 1997 May 30;276(5317):1408-12.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Section on Developmental Genetics, Heritable Disorders Branch, National Institute of Child Health and Human Development (NICHD), National Insitutes of Health (NIH), Bethesda, MD 20892-1830, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9162006" target="_blank"〉PubMed〈/a〉

    The sequence and de novo assembly of the giant panda genome (2009)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2009-12-17
    Description: Using next-generation sequencing technology alone, we have successfully generated and assembled a draft sequence of the giant panda genome. The assembled contigs (2.25 gigabases (Gb)) cover approximately 94% of the whole genome, and the remaining gaps (0.05 Gb) seem to contain carnivore-specific repeats and tandem repeats. Comparisons with the dog and human showed that the panda genome has a lower divergence rate. The assessment of panda genes potentially underlying some of its unique traits indicated that its bamboo diet might be more dependent on its gut microbiome than its own genetic composition. We also identified more than 2.7 million heterozygous single nucleotide polymorphisms in the diploid genome. Our data and analyses provide a foundation for promoting mammalian genetic research, and demonstrate the feasibility for using next-generation sequencing technologies for accurate, cost-effective and rapid de novo assembly of large eukaryotic genomes.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3951497/" 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/PMC3951497/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Li, Ruiqiang -- Fan, Wei -- Tian, Geng -- Zhu, Hongmei -- He, Lin -- Cai, Jing -- Huang, Quanfei -- Cai, Qingle -- Li, Bo -- Bai, Yinqi -- Zhang, Zhihe -- Zhang, Yaping -- Wang, Wen -- Li, Jun -- Wei, Fuwen -- Li, Heng -- Jian, Min -- Li, Jianwen -- Zhang, Zhaolei -- Nielsen, Rasmus -- Li, Dawei -- Gu, Wanjun -- Yang, Zhentao -- Xuan, Zhaoling -- Ryder, Oliver A -- Leung, Frederick Chi-Ching -- Zhou, Yan -- Cao, Jianjun -- Sun, Xiao -- Fu, Yonggui -- Fang, Xiaodong -- Guo, Xiaosen -- Wang, Bo -- Hou, Rong -- Shen, Fujun -- Mu, Bo -- Ni, Peixiang -- Lin, Runmao -- Qian, Wubin -- Wang, Guodong -- Yu, Chang -- Nie, Wenhui -- Wang, Jinhuan -- Wu, Zhigang -- Liang, Huiqing -- Min, Jiumeng -- Wu, Qi -- Cheng, Shifeng -- Ruan, Jue -- Wang, Mingwei -- Shi, Zhongbin -- Wen, Ming -- Liu, Binghang -- Ren, Xiaoli -- Zheng, Huisong -- Dong, Dong -- Cook, Kathleen -- Shan, Gao -- Zhang, Hao -- Kosiol, Carolin -- Xie, Xueying -- Lu, Zuhong -- Zheng, Hancheng -- Li, Yingrui -- Steiner, Cynthia C -- Lam, Tommy Tsan-Yuk -- Lin, Siyuan -- Zhang, Qinghui -- Li, Guoqing -- Tian, Jing -- Gong, Timing -- Liu, Hongde -- Zhang, Dejin -- Fang, Lin -- Ye, Chen -- Zhang, Juanbin -- Hu, Wenbo -- Xu, Anlong -- Ren, Yuanyuan -- Zhang, Guojie -- Bruford, Michael W -- Li, Qibin -- Ma, Lijia -- Guo, Yiran -- An, Na -- Hu, Yujie -- Zheng, Yang -- Shi, Yongyong -- Li, Zhiqiang -- Liu, Qing -- Chen, Yanling -- Zhao, Jing -- Qu, Ning -- Zhao, Shancen -- Tian, Feng -- Wang, Xiaoling -- Wang, Haiyin -- Xu, Lizhi -- Liu, Xiao -- Vinar, Tomas -- Wang, Yajun -- Lam, Tak-Wah -- Yiu, Siu-Ming -- Liu, Shiping -- Zhang, Hemin -- Li, Desheng -- Huang, Yan -- Wang, Xia -- Yang, Guohua -- Jiang, Zhi -- Wang, Junyi -- Qin, Nan -- Li, Li -- Li, Jingxiang -- Bolund, Lars -- Kristiansen, Karsten -- Wong, Gane Ka-Shu -- Olson, Maynard -- Zhang, Xiuqing -- Li, Songgang -- Yang, Huanming -- Wang, Jian -- Wang, Jun -- R01 HG003229/HG/NHGRI NIH HHS/ -- R01 HG003229-05/HG/NHGRI NIH HHS/ -- England -- Nature. 2010 Jan 21;463(7279):311-7. doi: 10.1038/nature08696.

    A mechanically stabilized receptor-ligand flex-bond important in the vasculature (2010)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2010-08-21
    Description: Haemostasis in the arteriolar circulation mediated by von Willebrand factor (VWF) binding to platelets is an example of an adhesive interaction that must withstand strong hydrodynamic forces acting on cells. VWF is a concatenated, multifunctional protein that has binding sites for platelets as well as subendothelial collagen. Binding of the A1 domain in VWF to the glycoprotein Ib alpha subunit (GPIbalpha) on the surface of platelets mediates crosslinking of platelets to one another and the formation of a platelet plug for arterioles. The importance of VWF is illustrated by its mutation in von Willebrand disease, a bleeding diathesis. Here, we describe a novel mechanochemical specialization of the A1-GPIbalpha bond for force-resistance. We have developed a method that enables, for the first time, repeated measurements of the binding and unbinding of a receptor and ligand in a single molecule (ReaLiSM). We demonstrate two states of the receptor-ligand bond, that is, a flex-bond. One state is seen at low force; a second state begins to engage at 10 pN with a approximately 20-fold longer lifetime and greater force resistance. The lifetimes of the two states, how force exponentiates lifetime, and the kinetics of switching between the two states are all measured. For the first time, single-molecule measurements on this system are in agreement with bulk phase measurements. The results have important implications not only for how platelets bound to VWF are able to resist force to plug arterioles, but also how increased flow activates platelet plug formation.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4117310/" 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/PMC4117310/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kim, Jongseong -- Zhang, Cheng-Zhong -- Zhang, Xiaohui -- Springer, Timothy A -- HL-48675/HL/NHLBI NIH HHS/ -- P01 HL048675/HL/NHLBI NIH HHS/ -- England -- Nature. 2010 Aug 19;466(7309):992-5. doi: 10.1038/nature09295.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Immune Disease Institute, Children's Hospital Boston and Department of Pathology, Harvard Medical School, 3 Blackfan Circle, Boston, Massachusetts 02115, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20725043" target="_blank"〉PubMed〈/a〉

    Description: The spread of H5N1 avian influenza viruses (AIVs) from China to Europe has raised global concern about their potential to infect humans and cause a pandemic. In spite of their substantial threat to human health, remarkably little AIV whole-genome information is available. We report here a preliminary analysis of the first large-scale sequencing of AIVs, including 2196 AIV genes and 169 complete genomes. We combine this new information with public AIV data to identify new gene alleles, persistent genotypes, compensatory mutations, and a potential virulence determinant.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Obenauer, John C -- Denson, Jackie -- Mehta, Perdeep K -- Su, Xiaoping -- Mukatira, Suraj -- Finkelstein, David B -- Xu, Xiequn -- Wang, Jinhua -- Ma, Jing -- Fan, Yiping -- Rakestraw, Karen M -- Webster, Robert G -- Hoffmann, Erich -- Krauss, Scott -- Zheng, Jie -- Zhang, Ziwei -- Naeve, Clayton W -- AI95357/AI/NIAID NIH HHS/ -- CA 21765/CA/NCI NIH HHS/ -- R01 GM061739/GM/NIGMS NIH HHS/ -- R01 GM069916/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2006 Mar 17;311(5767):1576-80.

    The genomic landscapes of human breast and colorectal cancers (2007)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2007-10-13
    Description: Human cancer is caused by the accumulation of mutations in oncogenes and tumor suppressor genes. To catalog the genetic changes that occur during tumorigenesis, we isolated DNA from 11 breast and 11 colorectal tumors and determined the sequences of the genes in the Reference Sequence database in these samples. Based on analysis of exons representing 20,857 transcripts from 18,191 genes, we conclude that the genomic landscapes of breast and colorectal cancers are composed of a handful of commonly mutated gene "mountains" and a much larger number of gene "hills" that are mutated at low frequency. We describe statistical and bioinformatic tools that may help identify mutations with a role in tumorigenesis. These results have implications for understanding the nature and heterogeneity of human cancers and for using personal genomics for tumor diagnosis and therapy.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wood, Laura D -- Parsons, D Williams -- Jones, Sian -- Lin, Jimmy -- Sjoblom, Tobias -- Leary, Rebecca J -- Shen, Dong -- Boca, Simina M -- Barber, Thomas -- Ptak, Janine -- Silliman, Natalie -- Szabo, Steve -- Dezso, Zoltan -- Ustyanksky, Vadim -- Nikolskaya, Tatiana -- Nikolsky, Yuri -- Karchin, Rachel -- Wilson, Paul A -- Kaminker, Joshua S -- Zhang, Zemin -- Croshaw, Randal -- Willis, Joseph -- Dawson, Dawn -- Shipitsin, Michail -- Willson, James K V -- Sukumar, Saraswati -- Polyak, Kornelia -- Park, Ben Ho -- Pethiyagoda, Charit L -- Pant, P V Krishna -- Ballinger, Dennis G -- Sparks, Andrew B -- Hartigan, James -- Smith, Douglas R -- Suh, Erick -- Papadopoulos, Nickolas -- Buckhaults, Phillip -- Markowitz, Sanford D -- Parmigiani, Giovanni -- Kinzler, Kenneth W -- Velculescu, Victor E -- Vogelstein, Bert -- CA 43460/CA/NCI NIH HHS/ -- CA 57345/CA/NCI NIH HHS/ -- CA109274/CA/NCI NIH HHS/ -- CA112828/CA/NCI NIH HHS/ -- CA121113/CA/NCI NIH HHS/ -- CA62924/CA/NCI NIH HHS/ -- GM070219/GM/NIGMS NIH HHS/ -- GM07309/GM/NIGMS NIH HHS/ -- P30-CA43703/CA/NCI NIH HHS/ -- RR017698/RR/NCRR NIH HHS/ -- New York, N.Y. -- Science. 2007 Nov 16;318(5853):1108-13.

    DUBA: a deubiquitinase that regulates type I interferon production (2007)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2007-11-10
    Description: Production of type I interferon (IFN-I) is a critical host defense triggered by pattern-recognition receptors (PRRs) of the innate immune system. Deubiquitinating enzyme A (DUBA), an ovarian tumor domain-containing deubiquitinating enzyme, was discovered in a small interfering RNA-based screen as a regulator of IFN-I production. Reduction of DUBA augmented the PRR-induced IFN-I response, whereas ectopic expression of DUBA had the converse effect. DUBA bound tumor necrosis factor receptor-associated factor 3 (TRAF3), an adaptor protein essential for the IFN-I response. TRAF3 is an E3 ubiquitin ligase that preferentially assembled lysine-63-linked polyubiquitin chains. DUBA selectively cleaved the lysine-63-linked polyubiquitin chains on TRAF3, resulting in its dissociation from the downstream signaling complex containing TANK-binding kinase 1. A discrete ubiquitin interaction motif within DUBA was required for efficient deubiquitination of TRAF3 and optimal suppression of IFN-I. Our data identify DUBA as a negative regulator of innate immune responses.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kayagaki, Nobuhiko -- Phung, Qui -- Chan, Salina -- Chaudhari, Ruchir -- Quan, Casey -- O'Rourke, Karen M -- Eby, Michael -- Pietras, Eric -- Cheng, Genhong -- Bazan, J Fernando -- Zhang, Zemin -- Arnott, David -- Dixit, Vishva M -- New York, N.Y. -- Science. 2007 Dec 7;318(5856):1628-32.

    Description: Acetylation of histone H3 lysine 56 (H3-K56) occurs in S phase, and cells lacking H3-K56 acetylation are sensitive to DNA-damaging agents. However, the histone acetyltransferase (HAT) that catalyzes global H3-K56 acetylation has not been found. Here we show that regulation of Ty1 transposition gene product 109 (Rtt109) is an H3-K56 HAT. Cells lacking Rtt109 or expressing rtt109 mutants with alterations at a conserved aspartate residue lose H3-K56 acetylation and exhibit increased sensitivity toward genotoxic agents, as well as elevated levels of spontaneous chromosome breaks. Thus, Rtt109, which shares no sequence homology with any other known HATs, is a unique HAT that acetylates H3-K56.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Han, Junhong -- Zhou, Hui -- Horazdovsky, Bruce -- Zhang, Kangling -- Xu, Rui-Ming -- Zhang, Zhiguo -- New York, N.Y. -- Science. 2007 Feb 2;315(5812):653-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biochemistry and Molecular Biology, Mayo Clinic College of Medicine, 200 First Street SW, Rochester, MN 55905, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17272723" target="_blank"〉PubMed〈/a〉
