    Publikationsdatum: 2008-10-25
    Beschreibung: Determining the genetic basis of cancer requires comprehensive analyses of large collections of histopathologically well-classified primary tumours. Here we report the results of a collaborative study to discover somatic mutations in 188 human lung adenocarcinomas. DNA sequencing of 623 genes with known or potential relationships to cancer revealed more than 1,000 somatic mutations across the samples. Our analysis identified 26 genes that are mutated at significantly high frequencies and thus are probably involved in carcinogenesis. The frequently mutated genes include tyrosine kinases, among them the EGFR homologue ERBB4; multiple ephrin receptor genes, notably EPHA3; vascular endothelial growth factor receptor KDR; and NTRK genes. These data provide evidence of somatic mutations in primary lung adenocarcinoma for several tumour suppressor genes involved in other cancers--including NF1, APC, RB1 and ATM--and for sequence changes in PTPRD as well as the frequently deleted gene LRP1B. The observed mutational profiles correlate with clinical features, smoking status and DNA repair defects. These results are reinforced by data integration including single nucleotide polymorphism array and gene expression array. Our findings shed further light on several important signalling pathways involved in lung adenocarcinoma, and suggest new molecular targets for treatment.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2694412/" 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/PMC2694412/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ding, Li -- Getz, Gad -- Wheeler, David A -- Mardis, Elaine R -- McLellan, Michael D -- Cibulskis, Kristian -- Sougnez, Carrie -- Greulich, Heidi -- Muzny, Donna M -- Morgan, Margaret B -- Fulton, Lucinda -- Fulton, Robert S -- Zhang, Qunyuan -- Wendl, Michael C -- Lawrence, Michael S -- Larson, David E -- Chen, Ken -- Dooling, David J -- Sabo, Aniko -- Hawes, Alicia C -- Shen, Hua -- Jhangiani, Shalini N -- Lewis, Lora R -- Hall, Otis -- Zhu, Yiming -- Mathew, Tittu -- Ren, Yanru -- Yao, Jiqiang -- Scherer, Steven E -- Clerc, Kerstin -- Metcalf, Ginger A -- Ng, Brian -- Milosavljevic, Aleksandar -- Gonzalez-Garay, Manuel L -- Osborne, John R -- Meyer, Rick -- Shi, Xiaoqi -- Tang, Yuzhu -- Koboldt, Daniel C -- Lin, Ling -- Abbott, Rachel -- Miner, Tracie L -- Pohl, Craig -- Fewell, Ginger -- Haipek, Carrie -- Schmidt, Heather -- Dunford-Shore, Brian H -- Kraja, Aldi -- Crosby, Seth D -- Sawyer, Christopher S -- Vickery, Tammi -- Sander, Sacha -- Robinson, Jody -- Winckler, Wendy -- Baldwin, Jennifer -- Chirieac, Lucian R -- Dutt, Amit -- Fennell, Tim -- Hanna, Megan -- Johnson, Bruce E -- Onofrio, Robert C -- Thomas, Roman K -- Tonon, Giovanni -- Weir, Barbara A -- Zhao, Xiaojun -- Ziaugra, Liuda -- Zody, Michael C -- Giordano, Thomas -- Orringer, Mark B -- Roth, Jack A -- Spitz, Margaret R -- Wistuba, Ignacio I -- Ozenberger, Bradley -- Good, Peter J -- Chang, Andrew C -- Beer, David G -- Watson, Mark A -- Ladanyi, Marc -- Broderick, Stephen -- Yoshizawa, Akihiko -- Travis, William D -- Pao, William -- Province, Michael A -- Weinstock, George M -- Varmus, Harold E -- Gabriel, Stacey B -- Lander, Eric S -- Gibbs, Richard A -- Meyerson, Matthew -- Wilson, Richard K -- P50 CA070907/CA/NCI NIH HHS/ -- R01 CA154365/CA/NCI NIH HHS/ -- U19 CA084953/CA/NCI NIH HHS/ -- U19 CA084953-050003/CA/NCI NIH HHS/ -- U54 HG003067/HG/NHGRI NIH HHS/ -- U54 HG003067-04/HG/NHGRI NIH HHS/ -- U54 HG003273/HG/NHGRI NIH HHS/ -- England -- Nature. 2008 Oct 23;455(7216):1069-75. doi: 10.1038/nature07423.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉The Genome Center at Washington University, Department of Genetics, Washington University School of Medicine, St Louis, Missouri 63108, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18948947" target="_blank"〉PubMed〈/a〉

    Substrate-targeting gamma-secretase modulators (2008)
    Nature Publishing Group (NPG)
    Details
    Publikationsdatum: 2008-06-13
    Beschreibung: Selective lowering of Abeta42 levels (the 42-residue isoform of the amyloid-beta peptide) with small-molecule gamma-secretase modulators (GSMs), such as some non-steroidal anti-inflammatory drugs, is a promising therapeutic approach for Alzheimer's disease. To identify the target of these agents we developed biotinylated photoactivatable GSMs. GSM photoprobes did not label the core proteins of the gamma-secretase complex, but instead labelled the beta-amyloid precursor protein (APP), APP carboxy-terminal fragments and amyloid-beta peptide in human neuroglioma H4 cells. Substrate labelling was competed by other GSMs, and labelling of an APP gamma-secretase substrate was more efficient than a Notch substrate. GSM interaction was localized to residues 28-36 of amyloid-beta, a region critical for aggregation. We also demonstrate that compounds known to interact with this region of amyloid-beta act as GSMs, and some GSMs alter the production of cell-derived amyloid-beta oligomers. Furthermore, mutation of the GSM binding site in the APP alters the sensitivity of the substrate to GSMs. These findings indicate that substrate targeting by GSMs mechanistically links two therapeutic actions: alteration in Abeta42 production and inhibition of amyloid-beta aggregation, which may synergistically reduce amyloid-beta deposition in Alzheimer's disease. These data also demonstrate the existence and feasibility of 'substrate targeting' by small-molecule effectors of proteolytic enzymes, which if generally applicable may significantly broaden the current notion of 'druggable' targets.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2678541/" 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/PMC2678541/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kukar, Thomas L -- Ladd, Thomas B -- Bann, Maralyssa A -- Fraering, Patrick C -- Narlawar, Rajeshwar -- Maharvi, Ghulam M -- Healy, Brent -- Chapman, Robert -- Welzel, Alfred T -- Price, Robert W -- Moore, Brenda -- Rangachari, Vijayaraghavan -- Cusack, Bernadette -- Eriksen, Jason -- Jansen-West, Karen -- Verbeeck, Christophe -- Yager, Debra -- Eckman, Christopher -- Ye, Wenjuan -- Sagi, Sarah -- Cottrell, Barbara A -- Torpey, Justin -- Rosenberry, Terrone L -- Fauq, Abdul -- Wolfe, Michael S -- Schmidt, Boris -- Walsh, Dominic M -- Koo, Edward H -- Golde, Todd E -- P01 AG020206/AG/NIA NIH HHS/ -- P01 AG020206-010002/AG/NIA NIH HHS/ -- R01 AG017574/AG/NIA NIH HHS/ -- R01 AG017574-08/AG/NIA NIH HHS/ -- R01 AG017574-09/AG/NIA NIH HHS/ -- R01 NS041355/NS/NINDS NIH HHS/ -- R01 NS041355-06A2/NS/NINDS NIH HHS/ -- R01 NS041355-07/NS/NINDS NIH HHS/ -- England -- Nature. 2008 Jun 12;453(7197):925-9. doi: 10.1038/nature07055.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Neuroscience, Mayo Clinic, Mayo Clinic College of Medicine, 4500 San Pablo Road, Jacksonville, Florida 32224, USA. kukar.thomas@mayo.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18548070" target="_blank"〉PubMed〈/a〉

    DNA double-strand breaks activate a multi-functional genetic program in developing lymphocytes (2008)
    Nature Publishing Group (NPG)
    Details
    Publikationsdatum: 2008-10-14
    Beschreibung: DNA double-strand breaks are generated by genotoxic agents and by cellular endonucleases as intermediates of several important physiological processes. The cellular response to genotoxic DNA breaks includes the activation of transcriptional programs known primarily to regulate cell-cycle checkpoints and cell survival. DNA double-strand breaks are generated in all developing lymphocytes during the assembly of antigen receptor genes, a process that is essential for normal lymphocyte development. Here we show that in murine lymphocytes these physiological DNA breaks activate a broad transcriptional program. This program transcends the canonical DNA double-strand break response and includes many genes that regulate diverse cellular processes important for lymphocyte development. Moreover, the expression of several of these genes is regulated similarly in response to genotoxic DNA damage. Thus, physiological DNA double-strand breaks provide cues that can regulate cell-type-specific processes not directly involved in maintaining the integrity of the genome, and genotoxic DNA breaks could disrupt normal cellular functions by corrupting these processes.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2605662/" 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/PMC2605662/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bredemeyer, Andrea L -- Helmink, Beth A -- Innes, Cynthia L -- Calderon, Boris -- McGinnis, Lisa M -- Mahowald, Grace K -- Gapud, Eric J -- Walker, Laura M -- Collins, Jennifer B -- Weaver, Brian K -- Mandik-Nayak, Laura -- Schreiber, Robert D -- Allen, Paul M -- May, Michael J -- Paules, Richard S -- Bassing, Craig H -- Sleckman, Barry P -- R01 AI047829/AI/NIAID NIH HHS/ -- R01 AI047829-09/AI/NIAID NIH HHS/ -- R01 CA125195/CA/NCI NIH HHS/ -- R01 CA125195-02/CA/NCI NIH HHS/ -- England -- Nature. 2008 Dec 11;456(7223):819-23. doi: 10.1038/nature07392.

    The sequence and de novo assembly of the giant panda genome (2009)
    Nature Publishing Group (NPG)
    Details
    Publikationsdatum: 2009-12-17
    Beschreibung: 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.

    Predicting new molecular targets for known drugs (2009)
    Nature Publishing Group (NPG)
    Details
    Publikationsdatum: 2009-11-03
    Beschreibung: Although drugs are intended to be selective, at least some bind to several physiological targets, explaining side effects and efficacy. Because many drug-target combinations exist, it would be useful to explore possible interactions computationally. Here we compared 3,665 US Food and Drug Administration (FDA)-approved and investigational drugs against hundreds of targets, defining each target by its ligands. Chemical similarities between drugs and ligand sets predicted thousands of unanticipated associations. Thirty were tested experimentally, including the antagonism of the beta(1) receptor by the transporter inhibitor Prozac, the inhibition of the 5-hydroxytryptamine (5-HT) transporter by the ion channel drug Vadilex, and antagonism of the histamine H(4) receptor by the enzyme inhibitor Rescriptor. Overall, 23 new drug-target associations were confirmed, five of which were potent (〈100 nM). The physiological relevance of one, the drug N,N-dimethyltryptamine (DMT) on serotonergic receptors, was confirmed in a knockout mouse. The chemical similarity approach is systematic and comprehensive, and may suggest side-effects and new indications for many drugs.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2784146/" 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/PMC2784146/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Keiser, Michael J -- Setola, Vincent -- Irwin, John J -- Laggner, Christian -- Abbas, Atheir I -- Hufeisen, Sandra J -- Jensen, Niels H -- Kuijer, Michael B -- Matos, Roberto C -- Tran, Thuy B -- Whaley, Ryan -- Glennon, Richard A -- Hert, Jerome -- Thomas, Kelan L H -- Edwards, Douglas D -- Shoichet, Brian K -- Roth, Bryan L -- R01 DA017204/DA/NIDA NIH HHS/ -- R01 DA017204-04/DA/NIDA NIH HHS/ -- R01 DA017204-05/DA/NIDA NIH HHS/ -- R01 MH061887/MH/NIMH NIH HHS/ -- R01 MH061887-09/MH/NIMH NIH HHS/ -- R01 MH061887-10/MH/NIMH NIH HHS/ -- U19 MH082441/MH/NIMH NIH HHS/ -- U19 MH082441-01/MH/NIMH NIH HHS/ -- U19 MH082441-010001/MH/NIMH NIH HHS/ -- U19 MH082441-019002/MH/NIMH NIH HHS/ -- U19 MH082441-019003/MH/NIMH NIH HHS/ -- U19 MH082441-02/MH/NIMH NIH HHS/ -- U19 MH082441-020001/MH/NIMH NIH HHS/ -- U19 MH082441-029002/MH/NIMH NIH HHS/ -- U19 MH082441-03/MH/NIMH NIH HHS/ -- U19 MH082441-030001/MH/NIMH NIH HHS/ -- U19 MH082441-039002/MH/NIMH NIH HHS/ -- England -- Nature. 2009 Nov 12;462(7270):175-81. doi: 10.1038/nature08506.

    Genome analysis of the platypus reveals unique signatures of evolution (2008)
    Nature Publishing Group (NPG)
    Details
    Publikationsdatum: 2008-05-10
    Beschreibung: We present a draft genome sequence of the platypus, Ornithorhynchus anatinus. This monotreme exhibits a fascinating combination of reptilian and mammalian characters. For example, platypuses have a coat of fur adapted to an aquatic lifestyle; platypus females lactate, yet lay eggs; and males are equipped with venom similar to that of reptiles. Analysis of the first monotreme genome aligned these features with genetic innovations. We find that reptile and platypus venom proteins have been co-opted independently from the same gene families; milk protein genes are conserved despite platypuses laying eggs; and immune gene family expansions are directly related to platypus biology. Expansions of protein, non-protein-coding RNA and microRNA families, as well as repeat elements, are identified. Sequencing of this genome now provides a valuable resource for deep mammalian comparative analyses, as well as for monotreme biology and conservation.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2803040/" 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/PMC2803040/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Warren, Wesley C -- Hillier, LaDeana W -- Marshall Graves, Jennifer A -- Birney, Ewan -- Ponting, Chris P -- Grutzner, Frank -- Belov, Katherine -- Miller, Webb -- Clarke, Laura -- Chinwalla, Asif T -- Yang, Shiaw-Pyng -- Heger, Andreas -- Locke, Devin P -- Miethke, Pat -- Waters, Paul D -- Veyrunes, Frederic -- Fulton, Lucinda -- Fulton, Bob -- Graves, Tina -- Wallis, John -- Puente, Xose S -- Lopez-Otin, Carlos -- Ordonez, Gonzalo R -- Eichler, Evan E -- Chen, Lin -- Cheng, Ze -- Deakin, Janine E -- Alsop, Amber -- Thompson, Katherine -- Kirby, Patrick -- Papenfuss, Anthony T -- Wakefield, Matthew J -- Olender, Tsviya -- Lancet, Doron -- Huttley, Gavin A -- Smit, Arian F A -- Pask, Andrew -- Temple-Smith, Peter -- Batzer, Mark A -- Walker, Jerilyn A -- Konkel, Miriam K -- Harris, Robert S -- Whittington, Camilla M -- Wong, Emily S W -- Gemmell, Neil J -- Buschiazzo, Emmanuel -- Vargas Jentzsch, Iris M -- Merkel, Angelika -- Schmitz, Juergen -- Zemann, Anja -- Churakov, Gennady -- Kriegs, Jan Ole -- Brosius, Juergen -- Murchison, Elizabeth P -- Sachidanandam, Ravi -- Smith, Carly -- Hannon, Gregory J -- Tsend-Ayush, Enkhjargal -- McMillan, Daniel -- Attenborough, Rosalind -- Rens, Willem -- Ferguson-Smith, Malcolm -- Lefevre, Christophe M -- Sharp, Julie A -- Nicholas, Kevin R -- Ray, David A -- Kube, Michael -- Reinhardt, Richard -- Pringle, Thomas H -- Taylor, James -- Jones, Russell C -- Nixon, Brett -- Dacheux, Jean-Louis -- Niwa, Hitoshi -- Sekita, Yoko -- Huang, Xiaoqiu -- Stark, Alexander -- Kheradpour, Pouya -- Kellis, Manolis -- Flicek, Paul -- Chen, Yuan -- Webber, Caleb -- Hardison, Ross -- Nelson, Joanne -- Hallsworth-Pepin, Kym -- Delehaunty, Kim -- Markovic, Chris -- Minx, Pat -- Feng, Yucheng -- Kremitzki, Colin -- Mitreva, Makedonka -- Glasscock, Jarret -- Wylie, Todd -- Wohldmann, Patricia -- Thiru, Prathapan -- Nhan, Michael N -- Pohl, Craig S -- Smith, Scott M -- Hou, Shunfeng -- Nefedov, Mikhail -- de Jong, Pieter J -- Renfree, Marilyn B -- Mardis, Elaine R -- Wilson, Richard K -- 062023/Wellcome Trust/United Kingdom -- HG002238/HG/NHGRI NIH HHS/ -- MC_U137761446/Medical Research Council/United Kingdom -- P01 CA013106/CA/NCI NIH HHS/ -- P01 CA013106-37/CA/NCI NIH HHS/ -- R01 GM59290/GM/NIGMS NIH HHS/ -- R01 HG002939/HG/NHGRI NIH HHS/ -- R01 HG004037/HG/NHGRI NIH HHS/ -- R01 HG004037-02/HG/NHGRI NIH HHS/ -- R01HG02385/HG/NHGRI NIH HHS/ -- Medical Research Council/United Kingdom -- England -- Nature. 2008 May 8;453(7192):175-83. doi: 10.1038/nature06936.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Genome Sequencing Center, Washington University School of Medicine, Campus Box 8501, 4444 Forest Park Avenue, St Louis, Missouri 63108, USA. wwarren@wustl.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18464734" target="_blank"〉PubMed〈/a〉

    Proteomic analysis of active multiple sclerosis lesions reveals therapeutic targets (2008)
    Nature Publishing Group (NPG)
    Details
    Publikationsdatum: 2008-02-19
    Beschreibung: Understanding the neuropathology of multiple sclerosis (MS) is essential for improved therapies. Therefore, identification of targets specific to pathological types of MS may have therapeutic benefits. Here we identify, by laser-capture microdissection and proteomics, proteins unique to three major types of MS lesions: acute plaque, chronic active plaque and chronic plaque. Comparative proteomic profiles identified tissue factor and protein C inhibitor within chronic active plaque samples, suggesting dysregulation of molecules associated with coagulation. In vivo administration of hirudin or recombinant activated protein C reduced disease severity in experimental autoimmune encephalomyelitis and suppressed Th1 and Th17 cytokines in astrocytes and immune cells. Administration of mutant forms of recombinant activated protein C showed that both its anticoagulant and its signalling functions were essential for optimal amelioration of experimental autoimmune encephalomyelitis. A proteomic approach illuminated potential therapeutic targets selective for specific pathological stages of MS and implicated participation of the coagulation cascade.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Han, May H -- Hwang, Sun-Il -- Roy, Dolly B -- Lundgren, Deborah H -- Price, Jordan V -- Ousman, Shalina S -- Fernald, Guy Haskin -- Gerlitz, Bruce -- Robinson, William H -- Baranzini, Sergio E -- Grinnell, Brian W -- Raine, Cedric S -- Sobel, Raymond A -- Han, David K -- Steinman, Lawrence -- T32 AI007290/AI/NIAID NIH HHS/ -- England -- Nature. 2008 Feb 28;451(7182):1076-81. doi: 10.1038/nature06559.

    A variant associated with nicotine dependence, lung cancer and peripheral arterial disease (2008)
    Nature Publishing Group (NPG)
    Details
    Publikationsdatum: 2008-04-04
    Beschreibung: Smoking is a leading cause of preventable death, causing about 5 million premature deaths worldwide each year. Evidence for genetic influence on smoking behaviour and nicotine dependence (ND) has prompted a search for susceptibility genes. Furthermore, assessing the impact of sequence variants on smoking-related diseases is important to public health. Smoking is the major risk factor for lung cancer (LC) and is one of the main risk factors for peripheral arterial disease (PAD). Here we identify a common variant in the nicotinic acetylcholine receptor gene cluster on chromosome 15q24 with an effect on smoking quantity, ND and the risk of two smoking-related diseases in populations of European descent. The variant has an effect on the number of cigarettes smoked per day in our sample of smokers. The same variant was associated with ND in a previous genome-wide association study that used low-quantity smokers as controls, and with a similar approach we observe a highly significant association with ND. A comparison of cases of LC and PAD with population controls each showed that the variant confers risk of LC and PAD. The findings provide a case study of a gene-environment interaction, highlighting the role of nicotine addiction in the pathology of other serious diseases.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4539558/" 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/PMC4539558/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Thorgeirsson, Thorgeir E -- Geller, Frank -- Sulem, Patrick -- Rafnar, Thorunn -- Wiste, Anna -- Magnusson, Kristinn P -- Manolescu, Andrei -- Thorleifsson, Gudmar -- Stefansson, Hreinn -- Ingason, Andres -- Stacey, Simon N -- Bergthorsson, Jon T -- Thorlacius, Steinunn -- Gudmundsson, Julius -- Jonsson, Thorlakur -- Jakobsdottir, Margret -- Saemundsdottir, Jona -- Olafsdottir, Olof -- Gudmundsson, Larus J -- Bjornsdottir, Gyda -- Kristjansson, Kristleifur -- Skuladottir, Halla -- Isaksson, Helgi J -- Gudbjartsson, Tomas -- Jones, Gregory T -- Mueller, Thomas -- Gottsater, Anders -- Flex, Andrea -- Aben, Katja K H -- de Vegt, Femmie -- Mulders, Peter F A -- Isla, Dolores -- Vidal, Maria J -- Asin, Laura -- Saez, Berta -- Murillo, Laura -- Blondal, Thorsteinn -- Kolbeinsson, Halldor -- Stefansson, Jon G -- Hansdottir, Ingunn -- Runarsdottir, Valgerdur -- Pola, Roberto -- Lindblad, Bengt -- van Rij, Andre M -- Dieplinger, Benjamin -- Haltmayer, Meinhard -- Mayordomo, Jose I -- Kiemeney, Lambertus A -- Matthiasson, Stefan E -- Oskarsson, Hogni -- Tyrfingsson, Thorarinn -- Gudbjartsson, Daniel F -- Gulcher, Jeffrey R -- Jonsson, Steinn -- Thorsteinsdottir, Unnur -- Kong, Augustine -- Stefansson, Kari -- R01 DA017932/DA/NIDA NIH HHS/ -- England -- Nature. 2008 Apr 3;452(7187):638-42. doi: 10.1038/nature06846.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉deCODE Genetics, 101 Reykjavik, Iceland. thorgeir@decode.is〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18385739" target="_blank"〉PubMed〈/a〉

    Biodiversity and biogeography of phages in modern stromatolites and thrombolites (2008)
    Nature Publishing Group (NPG)
    Details
    Publikationsdatum: 2008-03-04
    Beschreibung: Viruses, and more particularly phages (viruses that infect bacteria), represent one of the most abundant living entities in aquatic and terrestrial environments. The biogeography of phages has only recently been investigated and so far reveals a cosmopolitan distribution of phage genetic material (or genotypes). Here we address this cosmopolitan distribution through the analysis of phage communities in modern microbialites, the living representatives of one of the most ancient life forms on Earth. On the basis of a comparative metagenomic analysis of viral communities associated with marine (Highborne Cay, Bahamas) and freshwater (Pozas Azules II and Rio Mesquites, Mexico) microbialites, we show that some phage genotypes are geographically restricted. The high percentage of unknown sequences recovered from the three metagenomes (〉97%), the low percentage similarities with sequences from other environmental viral (n = 42) and microbial (n = 36) metagenomes, and the absence of viral genotypes shared among microbialites indicate that viruses are genetically unique in these environments. Identifiable sequences in the Highborne Cay metagenome were dominated by single-stranded DNA microphages that were not detected in any other samples examined, including sea water, fresh water, sediment, terrestrial, extreme, metazoan-associated and marine microbial mats. Finally, a marine signature was present in the phage community of the Pozas Azules II microbialites, even though this environment has not been in contact with the ocean for tens of millions of years. Taken together, these results prove that viruses in modern microbialites display biogeographical variability and suggest that they may be derived from an ancient community.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Desnues, Christelle -- Rodriguez-Brito, Beltran -- Rayhawk, Steve -- Kelley, Scott -- Tran, Tuong -- Haynes, Matthew -- Liu, Hong -- Furlan, Mike -- Wegley, Linda -- Chau, Betty -- Ruan, Yijun -- Hall, Dana -- Angly, Florent E -- Edwards, Robert A -- Li, Linlin -- Thurber, Rebecca Vega -- Reid, R Pamela -- Siefert, Janet -- Souza, Valeria -- Valentine, David L -- Swan, Brandon K -- Breitbart, Mya -- Rohwer, Forest -- England -- Nature. 2008 Mar 20;452(7185):340-3. doi: 10.1038/nature06735.

    Stream denitrification across biomes and its response to anthropogenic nitrate loading (2008)
    Nature Publishing Group (NPG)
    Details
    Publikationsdatum: 2008-03-14
    Beschreibung: Anthropogenic addition of bioavailable nitrogen to the biosphere is increasing and terrestrial ecosystems are becoming increasingly nitrogen-saturated, causing more bioavailable nitrogen to enter groundwater and surface waters. Large-scale nitrogen budgets show that an average of about 20-25 per cent of the nitrogen added to the biosphere is exported from rivers to the ocean or inland basins, indicating that substantial sinks for nitrogen must exist in the landscape. Streams and rivers may themselves be important sinks for bioavailable nitrogen owing to their hydrological connections with terrestrial systems, high rates of biological activity, and streambed sediment environments that favour microbial denitrification. Here we present data from nitrogen stable isotope tracer experiments across 72 streams and 8 regions representing several biomes. We show that total biotic uptake and denitrification of nitrate increase with stream nitrate concentration, but that the efficiency of biotic uptake and denitrification declines as concentration increases, reducing the proportion of in-stream nitrate that is removed from transport. Our data suggest that the total uptake of nitrate is related to ecosystem photosynthesis and that denitrification is related to ecosystem respiration. In addition, we use a stream network model to demonstrate that excess nitrate in streams elicits a disproportionate increase in the fraction of nitrate that is exported to receiving waters and reduces the relative role of small versus large streams as nitrate sinks.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Mulholland, Patrick J -- Helton, Ashley M -- Poole, Geoffrey C -- Hall, Robert O -- Hamilton, Stephen K -- Peterson, Bruce J -- Tank, Jennifer L -- Ashkenas, Linda R -- Cooper, Lee W -- Dahm, Clifford N -- Dodds, Walter K -- Findlay, Stuart E G -- Gregory, Stanley V -- Grimm, Nancy B -- Johnson, Sherri L -- McDowell, William H -- Meyer, Judy L -- Valett, H Maurice -- Webster, Jackson R -- Arango, Clay P -- Beaulieu, Jake J -- Bernot, Melody J -- Burgin, Amy J -- Crenshaw, Chelsea L -- Johnson, Laura T -- Niederlehner, B R -- O'Brien, Jonathan M -- Potter, Jody D -- Sheibley, Richard W -- Sobota, Daniel J -- Thomas, Suzanne M -- England -- Nature. 2008 Mar 13;452(7184):202-5. doi: 10.1038/nature06686.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Environmental Sciences Division, Oak Ridge National Laboratory, Oak Ridge, Tennessee 37831, USA. mulhollandpj@ornl.gov〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18337819" target="_blank"〉PubMed〈/a〉
