    Description: The rhesus macaque (Macaca mulatta) is an abundant primate species that diverged from the ancestors of Homo sapiens about 25 million years ago. Because they are genetically and physiologically similar to humans, rhesus monkeys are the most widely used nonhuman primate in basic and applied biomedical research. We determined the genome sequence of an Indian-origin Macaca mulatta female and compared the data with chimpanzees and humans to reveal the structure of ancestral primate genomes and to identify evidence for positive selection and lineage-specific expansions and contractions of gene families. A comparison of sequences from individual animals was used to investigate their underlying genetic diversity. The complete description of the macaque genome blueprint enhances the utility of this animal model for biomedical research and improves our understanding of the basic biology of the species.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Rhesus Macaque Genome Sequencing and Analysis Consortium -- Gibbs, Richard A -- Rogers, Jeffrey -- Katze, Michael G -- Bumgarner, Roger -- Weinstock, George M -- Mardis, Elaine R -- Remington, Karin A -- Strausberg, Robert L -- Venter, J Craig -- Wilson, Richard K -- Batzer, Mark A -- Bustamante, Carlos D -- Eichler, Evan E -- Hahn, Matthew W -- Hardison, Ross C -- Makova, Kateryna D -- Miller, Webb -- Milosavljevic, Aleksandar -- Palermo, Robert E -- Siepel, Adam -- Sikela, James M -- Attaway, Tony -- Bell, Stephanie -- Bernard, Kelly E -- Buhay, Christian J -- Chandrabose, Mimi N -- Dao, Marvin -- Davis, Clay -- Delehaunty, Kimberly D -- Ding, Yan -- Dinh, Huyen H -- Dugan-Rocha, Shannon -- Fulton, Lucinda A -- Gabisi, Ramatu Ayiesha -- Garner, Toni T -- Godfrey, Jennifer -- Hawes, Alicia C -- Hernandez, Judith -- Hines, Sandra -- Holder, Michael -- Hume, Jennifer -- Jhangiani, Shalini N -- Joshi, Vandita -- Khan, Ziad Mohid -- Kirkness, Ewen F -- Cree, Andrew -- Fowler, R Gerald -- Lee, Sandra -- Lewis, Lora R -- Li, Zhangwan -- Liu, Yih-Shin -- Moore, Stephanie M -- Muzny, Donna -- Nazareth, Lynne V -- Ngo, Dinh Ngoc -- Okwuonu, Geoffrey O -- Pai, Grace -- Parker, David -- Paul, Heidie A -- Pfannkoch, Cynthia -- Pohl, Craig S -- Rogers, Yu-Hui -- Ruiz, San Juana -- Sabo, Aniko -- Santibanez, Jireh -- Schneider, Brian W -- Smith, Scott M -- Sodergren, Erica -- Svatek, Amanda F -- Utterback, Teresa R -- Vattathil, Selina -- Warren, Wesley -- White, Courtney Sherell -- Chinwalla, Asif T -- Feng, Yucheng -- Halpern, Aaron L -- Hillier, Ladeana W -- Huang, Xiaoqiu -- Minx, Pat -- Nelson, Joanne O -- Pepin, Kymberlie H -- Qin, Xiang -- Sutton, Granger G -- Venter, Eli -- Walenz, Brian P -- Wallis, John W -- Worley, Kim C -- Yang, Shiaw-Pyng -- Jones, Steven M -- Marra, Marco A -- Rocchi, Mariano -- Schein, Jacqueline E -- Baertsch, Robert -- Clarke, Laura -- Csuros, Miklos -- Glasscock, Jarret -- Harris, R Alan -- Havlak, Paul -- Jackson, Andrew R -- Jiang, Huaiyang -- Liu, Yue -- Messina, David N -- Shen, Yufeng -- Song, Henry Xing-Zhi -- Wylie, Todd -- Zhang, Lan -- Birney, Ewan -- Han, Kyudong -- Konkel, Miriam K -- Lee, Jungnam -- Smit, Arian F A -- Ullmer, Brygg -- Wang, Hui -- Xing, Jinchuan -- Burhans, Richard -- Cheng, Ze -- Karro, John E -- Ma, Jian -- Raney, Brian -- She, Xinwei -- Cox, Michael J -- Demuth, Jeffery P -- Dumas, Laura J -- Han, Sang-Gook -- Hopkins, Janet -- Karimpour-Fard, Anis -- Kim, Young H -- Pollack, Jonathan R -- Vinar, Tomas -- Addo-Quaye, Charles -- Degenhardt, Jeremiah -- Denby, Alexandra -- Hubisz, Melissa J -- Indap, Amit -- Kosiol, Carolin -- Lahn, Bruce T -- Lawson, Heather A -- Marklein, Alison -- Nielsen, Rasmus -- Vallender, Eric J -- Clark, Andrew G -- Ferguson, Betsy -- Hernandez, Ryan D -- Hirani, Kashif -- Kehrer-Sawatzki, Hildegard -- Kolb, Jessica -- Patil, Shobha -- Pu, Ling-Ling -- Ren, Yanru -- Smith, David Glenn -- Wheeler, David A -- Schenck, Ian -- Ball, Edward V -- Chen, Rui -- Cooper, David N -- Giardine, Belinda -- Hsu, Fan -- Kent, W James -- Lesk, Arthur -- Nelson, David L -- O'brien, William E -- Prufer, Kay -- Stenson, Peter D -- Wallace, James C -- Ke, Hui -- Liu, Xiao-Ming -- Wang, Peng -- Xiang, Andy Peng -- Yang, Fan -- Barber, Galt P -- Haussler, David -- Karolchik, Donna -- Kern, Andy D -- Kuhn, Robert M -- Smith, Kayla E -- Zwieg, Ann S -- 062023/Wellcome Trust/United Kingdom -- R01 HG002939/HG/NHGRI NIH HHS/ -- U54 HG003068/HG/NHGRI NIH HHS/ -- U54 HG003079/HG/NHGRI NIH HHS/ -- U54 HG003273/HG/NHGRI NIH HHS/ -- New York, N.Y. -- Science. 2007 Apr 13;316(5822):222-34.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Human Genome Sequencing Center, Baylor College of Medicine, Houston, TX 77030, USA. agibbs@bcm.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17431167" target="_blank"〉PubMed〈/a〉

    Description: The imprints of domestication and breed development on the genomes of livestock likely differ from those of companion animals. A deep draft sequence assembly of shotgun reads from a single Hereford female and comparative sequences sampled from six additional breeds were used to develop probes to interrogate 37,470 single-nucleotide polymorphisms (SNPs) in 497 cattle from 19 geographically and biologically diverse breeds. These data show that cattle have undergone a rapid recent decrease in effective population size from a very large ancestral population, possibly due to bottlenecks associated with domestication, selection, and breed formation. Domestication and artificial selection appear to have left detectable signatures of selection within the cattle genome, yet the current levels of diversity within breeds are at least as great as exists within humans.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2735092/" 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/PMC2735092/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bovine HapMap Consortium -- Gibbs, Richard A -- Taylor, Jeremy F -- Van Tassell, Curtis P -- Barendse, William -- Eversole, Kellye A -- Gill, Clare A -- Green, Ronnie D -- Hamernik, Debora L -- Kappes, Steven M -- Lien, Sigbjorn -- Matukumalli, Lakshmi K -- McEwan, John C -- Nazareth, Lynne V -- Schnabel, Robert D -- Weinstock, George M -- Wheeler, David A -- Ajmone-Marsan, Paolo -- Boettcher, Paul J -- Caetano, Alexandre R -- Garcia, Jose Fernando -- Hanotte, Olivier -- Mariani, Paola -- Skow, Loren C -- Sonstegard, Tad S -- Williams, John L -- Diallo, Boubacar -- Hailemariam, Lemecha -- Martinez, Mario L -- Morris, Chris A -- Silva, Luiz O C -- Spelman, Richard J -- Mulatu, Woudyalew -- Zhao, Keyan -- Abbey, Colette A -- Agaba, Morris -- Araujo, Flabio R -- Bunch, Rowan J -- Burton, James -- Gorni, Chiara -- Olivier, Hanotte -- Harrison, Blair E -- Luff, Bill -- Machado, Marco A -- Mwakaya, Joel -- Plastow, Graham -- Sim, Warren -- Smith, Timothy -- Thomas, Merle B -- Valentini, Alessio -- Williams, Paul -- Womack, James -- Woolliams, John A -- Liu, Yue -- Qin, Xiang -- Worley, Kim C -- Gao, Chuan -- Jiang, Huaiyang -- Moore, Stephen S -- Ren, Yanru -- Song, Xing-Zhi -- Bustamante, Carlos D -- Hernandez, Ryan D -- Muzny, Donna M -- Patil, Shobha -- San Lucas, Anthony -- Fu, Qing -- Kent, Matthew P -- Vega, Richard -- Matukumalli, Aruna -- McWilliam, Sean -- Sclep, Gert -- Bryc, Katarzyna -- Choi, Jungwoo -- Gao, Hong -- Grefenstette, John J -- Murdoch, Brenda -- Stella, Alessandra -- Villa-Angulo, Rafael -- Wright, Mark -- Aerts, Jan -- Jann, Oliver -- Negrini, Riccardo -- Goddard, Mike E -- Hayes, Ben J -- Bradley, Daniel G -- Barbosa da Silva, Marcos -- Lau, Lilian P L -- Liu, George E -- Lynn, David J -- Panzitta, Francesca -- Dodds, Ken G -- R01 GM083606/GM/NIGMS NIH HHS/ -- R01 GM083606-02/GM/NIGMS NIH HHS/ -- U54 HG003273/HG/NHGRI NIH HHS/ -- New York, N.Y. -- Science. 2009 Apr 24;324(5926):528-32. doi: 10.1126/science.1167936.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19390050" target="_blank"〉PubMed〈/a〉

    Description: 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〉

    Description: Some Toll and Toll-like receptors (TLRs) provide immunity to experimental infections in animal models, but their contribution to host defense in natural ecosystems is unknown. We report a dominant-negative TLR3 allele in otherwise healthy children with herpes simplex virus 1 (HSV-1) encephalitis. TLR3 is expressed in the central nervous system (CNS), where it is required to control HSV-1, which spreads from the epithelium to the CNS via cranial nerves. TLR3 is also expressed in epithelial and dendritic cells, which apparently use TLR3-independent pathways to prevent further dissemination of HSV-1 and to provide resistance to other pathogens in TLR3-deficient patients. Human TLR3 appears to be redundant in host defense to most microbes but is vital for natural immunity to HSV-1 in the CNS, which suggests that neurotropic viruses have contributed to the evolutionary maintenance of TLR3.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Zhang, Shen-Ying -- Jouanguy, Emmanuelle -- Ugolini, Sophie -- Smahi, Asma -- Elain, Gaelle -- Romero, Pedro -- Segal, David -- Sancho-Shimizu, Vanessa -- Lorenzo, Lazaro -- Puel, Anne -- Picard, Capucine -- Chapgier, Ariane -- Plancoulaine, Sabine -- Titeux, Matthias -- Cognet, Celine -- von Bernuth, Horst -- Ku, Cheng-Lung -- Casrouge, Armanda -- Zhang, Xin-Xin -- Barreiro, Luis -- Leonard, Joshua -- Hamilton, Claire -- Lebon, Pierre -- Heron, Benedicte -- Vallee, Louis -- Quintana-Murci, Lluis -- Hovnanian, Alain -- Rozenberg, Flore -- Vivier, Eric -- Geissmann, Frederic -- Tardieu, Marc -- Abel, Laurent -- Casanova, Jean-Laurent -- G0900867/Medical Research Council/United Kingdom -- New York, N.Y. -- Science. 2007 Sep 14;317(5844):1522-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Human Genetics of Infectious Diseases, Institut National de la Sante et de la Recherche Medicale (INSERM), U550, Faculty Necker, Paris 75015, France.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17872438" target="_blank"〉PubMed〈/a〉

    Description: Parasites can have strong impacts but are thought to contribute little biomass to ecosystems. We quantified the biomass of free-living and parasitic species in three estuaries on the Pacific coast of California and Baja California. Here we show that parasites have substantial biomass in these ecosystems. We found that parasite biomass exceeded that of top predators. The biomass of trematodes was particularly high, being comparable to that of the abundant birds, fishes, burrowing shrimps and polychaetes. Trophically transmitted parasites and parasitic castrators subsumed more biomass than did other parasitic functional groups. The extended phenotype biomass controlled by parasitic castrators sometimes exceeded that of their uninfected hosts. The annual production of free-swimming trematode transmission stages was greater than the combined biomass of all quantified parasites and was also greater than bird biomass. This biomass and productivity of parasites implies a profound role for infectious processes in these estuaries.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kuris, Armand M -- Hechinger, Ryan F -- Shaw, Jenny C -- Whitney, Kathleen L -- Aguirre-Macedo, Leopoldina -- Boch, Charlie A -- Dobson, Andrew P -- Dunham, Eleca J -- Fredensborg, Brian L -- Huspeni, Todd C -- Lorda, Julio -- Mababa, Luzviminda -- Mancini, Frank T -- Mora, Adrienne B -- Pickering, Maria -- Talhouk, Nadia L -- Torchin, Mark E -- Lafferty, Kevin D -- England -- Nature. 2008 Jul 24;454(7203):515-8. doi: 10.1038/nature06970.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Ecology, Evolution and Marine Biology and Marine Science Institute, University of California, Santa Barbara, California 93106, USA. kuris@lifesci.ucsb.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18650923" target="_blank"〉PubMed〈/a〉

    Description: Amazon forests are a key but poorly understood component of the global carbon cycle. If, as anticipated, they dry this century, they might accelerate climate change through carbon losses and changed surface energy balances. We used records from multiple long-term monitoring plots across Amazonia to assess forest responses to the intense 2005 drought, a possible analog of future events. Affected forest lost biomass, reversing a large long-term carbon sink, with the greatest impacts observed where the dry season was unusually intense. Relative to pre-2005 conditions, forest subjected to a 100-millimeter increase in water deficit lost 5.3 megagrams of aboveground biomass of carbon per hectare. The drought had a total biomass carbon impact of 1.2 to 1.6 petagrams (1.2 x 10(15) to 1.6 x 10(15) grams). Amazon forests therefore appear vulnerable to increasing moisture stress, with the potential for large carbon losses to exert feedback on climate change.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Phillips, Oliver L -- Aragao, Luiz E O C -- Lewis, Simon L -- Fisher, Joshua B -- Lloyd, Jon -- Lopez-Gonzalez, Gabriela -- Malhi, Yadvinder -- Monteagudo, Abel -- Peacock, Julie -- Quesada, Carlos A -- van der Heijden, Geertje -- Almeida, Samuel -- Amaral, Ieda -- Arroyo, Luzmila -- Aymard, Gerardo -- Baker, Tim R -- Banki, Olaf -- Blanc, Lilian -- Bonal, Damien -- Brando, Paulo -- Chave, Jerome -- de Oliveira, Atila Cristina Alves -- Cardozo, Nallaret Davila -- Czimczik, Claudia I -- Feldpausch, Ted R -- Freitas, Maria Aparecida -- Gloor, Emanuel -- Higuchi, Niro -- Jimenez, Eliana -- Lloyd, Gareth -- Meir, Patrick -- Mendoza, Casimiro -- Morel, Alexandra -- Neill, David A -- Nepstad, Daniel -- Patino, Sandra -- Penuela, Maria Cristina -- Prieto, Adriana -- Ramirez, Fredy -- Schwarz, Michael -- Silva, Javier -- Silveira, Marcos -- Thomas, Anne Sota -- Steege, Hans Ter -- Stropp, Juliana -- Vasquez, Rodolfo -- Zelazowski, Przemyslaw -- Alvarez Davila, Esteban -- Andelman, Sandy -- Andrade, Ana -- Chao, Kuo-Jung -- Erwin, Terry -- Di Fiore, Anthony -- Honorio C, Euridice -- Keeling, Helen -- Killeen, Tim J -- Laurance, William F -- Pena Cruz, Antonio -- Pitman, Nigel C A -- Nunez Vargas, Percy -- Ramirez-Angulo, Hirma -- Rudas, Agustin -- Salamao, Rafael -- Silva, Natalino -- Terborgh, John -- Torres-Lezama, Armando -- New York, N.Y. -- Science. 2009 Mar 6;323(5919):1344-7. doi: 10.1126/science.1164033.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Ecology and Global Change, School of Geography, University of Leeds, Leeds LS2 9JT, UK. o.phillips@leeds.ac.uk〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19265020" target="_blank"〉PubMed〈/a〉

    Description: Microbial activities shape the biogeochemistry of the planet and macroorganism health. Determining the metabolic processes performed by microbes is important both for understanding and for manipulating ecosystems (for example, disruption of key processes that lead to disease, conservation of environmental services, and so on). Describing microbial function is hampered by the inability to culture most microbes and by high levels of genomic plasticity. Metagenomic approaches analyse microbial communities to determine the metabolic processes that are important for growth and survival in any given environment. Here we conduct a metagenomic comparison of almost 15 million sequences from 45 distinct microbiomes and, for the first time, 42 distinct viromes and show that there are strongly discriminatory metabolic profiles across environments. Most of the functional diversity was maintained in all of the communities, but the relative occurrence of metabolisms varied, and the differences between metagenomes predicted the biogeochemical conditions of each environment. The magnitude of the microbial metabolic capabilities encoded by the viromes was extensive, suggesting that they serve as a repository for storing and sharing genes among their microbial hosts and influence global evolutionary and metabolic processes.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Dinsdale, Elizabeth A -- Edwards, Robert A -- Hall, Dana -- Angly, Florent -- Breitbart, Mya -- Brulc, Jennifer M -- Furlan, Mike -- Desnues, Christelle -- Haynes, Matthew -- Li, Linlin -- McDaniel, Lauren -- Moran, Mary Ann -- Nelson, Karen E -- Nilsson, Christina -- Olson, Robert -- Paul, John -- Brito, Beltran Rodriguez -- Ruan, Yijun -- Swan, Brandon K -- Stevens, Rick -- Valentine, David L -- Thurber, Rebecca Vega -- Wegley, Linda -- White, Bryan A -- Rohwer, Forest -- England -- Nature. 2008 Apr 3;452(7187):629-32. doi: 10.1038/nature06810.

    Description: Acute myeloid leukaemia is a highly malignant haematopoietic tumour that affects about 13,000 adults in the United States each year. The treatment of this disease has changed little in the past two decades, because most of the genetic events that initiate the disease remain undiscovered. Whole-genome sequencing is now possible at a reasonable cost and timeframe to use this approach for the unbiased discovery of tumour-specific somatic mutations that alter the protein-coding genes. Here we present the results obtained from sequencing a typical acute myeloid leukaemia genome, and its matched normal counterpart obtained from the same patient's skin. We discovered ten genes with acquired mutations; two were previously described mutations that are thought to contribute to tumour progression, and eight were new mutations present in virtually all tumour cells at presentation and relapse, the function of which is not yet known. Our study establishes whole-genome sequencing as an unbiased method for discovering cancer-initiating mutations in previously unidentified genes that may respond to targeted therapies.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2603574/" 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/PMC2603574/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ley, Timothy J -- Mardis, Elaine R -- Ding, Li -- Fulton, Bob -- McLellan, Michael D -- Chen, Ken -- Dooling, David -- Dunford-Shore, Brian H -- McGrath, Sean -- Hickenbotham, Matthew -- Cook, Lisa -- Abbott, Rachel -- Larson, David E -- Koboldt, Dan C -- Pohl, Craig -- Smith, Scott -- Hawkins, Amy -- Abbott, Scott -- Locke, Devin -- Hillier, Ladeana W -- Miner, Tracie -- Fulton, Lucinda -- Magrini, Vincent -- Wylie, Todd -- Glasscock, Jarret -- Conyers, Joshua -- Sander, Nathan -- Shi, Xiaoqi -- Osborne, John R -- Minx, Patrick -- Gordon, David -- Chinwalla, Asif -- Zhao, Yu -- Ries, Rhonda E -- Payton, Jacqueline E -- Westervelt, Peter -- Tomasson, Michael H -- Watson, Mark -- Baty, Jack -- Ivanovich, Jennifer -- Heath, Sharon -- Shannon, William D -- Nagarajan, Rakesh -- Walter, Matthew J -- Link, Daniel C -- Graubert, Timothy A -- DiPersio, John F -- Wilson, Richard K -- U54 HG002042/HG/NHGRI NIH HHS/ -- U54 HG002042-05/HG/NHGRI NIH HHS/ -- England -- Nature. 2008 Nov 6;456(7218):66-72. doi: 10.1038/nature07485.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Medicine, 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/18987736" target="_blank"〉PubMed〈/a〉

    Description: Aortic aneurysm and dissection are manifestations of Marfan syndrome (MFS), a disorder caused by mutations in the gene that encodes fibrillin-1. Selected manifestations of MFS reflect excessive signaling by the transforming growth factor-beta (TGF-beta) family of cytokines. We show that aortic aneurysm in a mouse model of MFS is associated with increased TGF-beta signaling and can be prevented by TGF-beta antagonists such as TGF-beta-neutralizing antibody or the angiotensin II type 1 receptor (AT1) blocker, losartan. AT1 antagonism also partially reversed noncardiovascular manifestations of MFS, including impaired alveolar septation. These data suggest that losartan, a drug already in clinical use for hypertension, merits investigation as a therapeutic strategy for patients with MFS and has the potential to prevent the major life-threatening manifestation of this disorder.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC1482474/" 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/PMC1482474/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Habashi, Jennifer P -- Judge, Daniel P -- Holm, Tammy M -- Cohn, Ronald D -- Loeys, Bart L -- Cooper, Timothy K -- Myers, Loretha -- Klein, Erin C -- Liu, Guosheng -- Calvi, Carla -- Podowski, Megan -- Neptune, Enid R -- Halushka, Marc K -- Bedja, Djahida -- Gabrielson, Kathleen -- Rifkin, Daniel B -- Carta, Luca -- Ramirez, Francesco -- Huso, David L -- Dietz, Harry C -- K08 HL067056/HL/NHLBI NIH HHS/ -- New York, N.Y. -- Science. 2006 Apr 7;312(5770):117-21.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Howard Hughes Medical Institute and Department of Pediatrics, Johns Hopkins University School of Medicine, Baltimore, MD 21205, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16601194" target="_blank"〉PubMed〈/a〉
