    Description: The interleukin-1beta (IL-1beta) converting enzyme (ICE) processes the inactive IL-1beta precursor to the proinflammatory cytokine. ICE was also shown to cleave the precursor of interferon-gamma inducing factor (IGIF) at the authentic processing site with high efficiency, thereby activating IGIF and facilitating its export. Lipopolysaccharide-activated ICE-deficient (ICE-/-) Kupffer cells synthesized the IGIF precursor but failed to process it into the active form. Interferon-gamma and IGIF were diminished in the sera of ICE-/- mice exposed to Propionibacterium acnes and lipopolysaccharide. The lack of multiple proinflammatory cytokines in ICE-/- mice may account for their protection from septic shock.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gu, Y -- Kuida, K -- Tsutsui, H -- Ku, G -- Hsiao, K -- Fleming, M A -- Hayashi, N -- Higashino, K -- Okamura, H -- Nakanishi, K -- Kurimoto, M -- Tanimoto, T -- Flavell, R A -- Sato, V -- Harding, M W -- Livingston, D J -- Su, M S -- New York, N.Y. -- Science. 1997 Jan 10;275(5297):206-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Vertex Pharmaceuticals, Inc., 130 Waverly Street, Cambridge, MA 02139, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8999548" target="_blank"〉PubMed〈/a〉

    Description: The Rho guanosine triphosphatases (GTPases) Rac1 and Rac2 are critical signaling regulators in mammalian cells. The deletion of both Rac1 and Rac2 murine alleles leads to a massive egress of hematopoietic stem/progenitor cells (HSC/Ps) into the blood from the marrow, whereas Rac1-/- but not Rac2-/- HSC/Ps fail to engraft in the bone marrow of irradiated recipient mice. In contrast, Rac2, but not Rac1, regulates superoxide production and directed migration in neutrophils, and in each cell type, the two GTPases play distinct roles in actin organization, cell survival, and proliferation. Thus, Rac1 and Rac2 regulate unique aspects of hematopoietic development and function.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gu, Yi -- Filippi, Marie-Dominique -- Cancelas, Jose A -- Siefring, Jamie E -- Williams, Emily P -- Jasti, Aparna C -- Harris, Chad E -- Lee, Andrew W -- Prabhakar, Rethinasamy -- Atkinson, Simon J -- Kwiatkowski, David J -- Williams, David A -- DK62757/DK/NIDDK NIH HHS/ -- New York, N.Y. -- Science. 2003 Oct 17;302(5644):445-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Division of Experimental Hematology, Cincinnati Children's Hospital Medical Center, Cincinnati, OH 45229, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/14564009" target="_blank"〉PubMed〈/a〉

    Description: We investigated extraneural manifestations in scrapie-infected transgenic mice expressing prion protein lacking the glycophosphatydylinositol membrane anchor. In the brain, blood, and heart, both abnormal protease-resistant prion protein (PrPres) and prion infectivity were readily detected by immunoblot and by inoculation into nontransgenic recipients. The titer of infectious scrapie in blood plasma exceeded 10(7) 50% infectious doses per milliliter. The hearts of these transgenic mice contained PrPres-positive amyloid deposits that led to myocardial stiffness and cardiac disease.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC1820586/" 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/PMC1820586/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Trifilo, Matthew J -- Yajima, Toshitaka -- Gu, Yusu -- Dalton, Nancy -- Peterson, Kirk L -- Race, Richard E -- Meade-White, Kimberly -- Portis, John L -- Masliah, Eliezer -- Knowlton, Kirk U -- Chesebro, Bruce -- Oldstone, Michael B A -- 5R01HL66424-04/HL/NHLBI NIH HHS/ -- AGO4342/PHS HHS/ -- NS041219-05/NS/NINDS NIH HHS/ -- P01 AG004342/AG/NIA NIH HHS/ -- New York, N.Y. -- Science. 2006 Jul 7;313(5783):94-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Viral-Immunobiology Laboratory, Departments of Molecular and Integrative Neurosciences and Infectology, Scripps Research Institute, La Jolla, CA 92037, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16825571" target="_blank"〉PubMed〈/a〉

    Description: Adult neurogenesis arises from neural stem cells within specialized niches. Neuronal activity and experience, presumably acting on this local niche, regulate multiple stages of adult neurogenesis, from neural progenitor proliferation to new neuron maturation, synaptic integration and survival. It is unknown whether local neuronal circuitry has a direct impact on adult neural stem cells. Here we show that, in the adult mouse hippocampus, nestin-expressing radial glia-like quiescent neural stem cells (RGLs) respond tonically to the neurotransmitter gamma-aminobutyric acid (GABA) by means of gamma2-subunit-containing GABAA receptors. Clonal analysis of individual RGLs revealed a rapid exit from quiescence and enhanced symmetrical self-renewal after conditional deletion of gamma2. RGLs are in close proximity to terminals expressing 67-kDa glutamic acid decarboxylase (GAD67) of parvalbumin-expressing (PV+) interneurons and respond tonically to GABA released from these neurons. Functionally, optogenetic control of the activity of dentate PV+ interneurons, but not that of somatostatin-expressing or vasoactive intestinal polypeptide (VIP)-expressing interneurons, can dictate the RGL choice between quiescence and activation. Furthermore, PV+ interneuron activation restores RGL quiescence after social isolation, an experience that induces RGL activation and symmetrical division. Our study identifies a niche cell-signal-receptor trio and a local circuitry mechanism that control the activation and self-renewal mode of quiescent adult neural stem cells in response to neuronal activity and experience.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3438284/" 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/PMC3438284/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Song, Juan -- Zhong, Chun -- Bonaguidi, Michael A -- Sun, Gerald J -- Hsu, Derek -- Gu, Yan -- Meletis, Konstantinos -- Huang, Z Josh -- Ge, Shaoyu -- Enikolopov, Grigori -- Deisseroth, Karl -- Luscher, Bernhard -- Christian, Kimberly M -- Ming, Guo-li -- Song, Hongjun -- AG040209/AG/NIA NIH HHS/ -- HD069184/HD/NICHD NIH HHS/ -- MH089111/MH/NIMH NIH HHS/ -- NS048271/NS/NINDS NIH HHS/ -- R01 AG040209/AG/NIA NIH HHS/ -- R01 HD069184/HD/NICHD NIH HHS/ -- R01 NS047344/NS/NINDS NIH HHS/ -- R01 NS048271/NS/NINDS NIH HHS/ -- R01 NS065915/NS/NINDS NIH HHS/ -- R21 ES021957/ES/NIEHS NIH HHS/ -- R56 NS047344/NS/NINDS NIH HHS/ -- England -- Nature. 2012 Sep 6;489(7414):150-4. doi: 10.1038/nature11306.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Institute for Cell Engineering, Johns Hopkins University School of Medicine, Baltimore, Maryland 21205, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/22842902" target="_blank"〉PubMed〈/a〉

    Description: Zebrafish have become a popular organism for the study of vertebrate gene function. The virtually transparent embryos of this species, and the ability to accelerate genetic studies by gene knockdown or overexpression, have led to the widespread use of zebrafish in the detailed investigation of vertebrate gene function and increasingly, the study of human genetic disease. However, for effective modelling of human genetic disease it is important to understand the extent to which zebrafish genes and gene structures are related to orthologous human genes. To examine this, we generated a high-quality sequence assembly of the zebrafish genome, made up of an overlapping set of completely sequenced large-insert clones that were ordered and oriented using a high-resolution high-density meiotic map. Detailed automatic and manual annotation provides evidence of more than 26,000 protein-coding genes, the largest gene set of any vertebrate so far sequenced. Comparison to the human reference genome shows that approximately 70% of human genes have at least one obvious zebrafish orthologue. In addition, the high quality of this genome assembly provides a clearer understanding of key genomic features such as a unique repeat content, a scarcity of pseudogenes, an enrichment of zebrafish-specific genes on chromosome 4 and chromosomal regions that influence sex determination.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3703927/" 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/PMC3703927/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Howe, Kerstin -- Clark, Matthew D -- Torroja, Carlos F -- Torrance, James -- Berthelot, Camille -- Muffato, Matthieu -- Collins, John E -- Humphray, Sean -- McLaren, Karen -- Matthews, Lucy -- McLaren, Stuart -- Sealy, Ian -- Caccamo, Mario -- Churcher, Carol -- Scott, Carol -- Barrett, Jeffrey C -- Koch, Romke -- Rauch, Gerd-Jorg -- White, Simon -- Chow, William -- Kilian, Britt -- Quintais, Leonor T -- Guerra-Assuncao, Jose A -- Zhou, Yi -- Gu, Yong -- Yen, Jennifer -- Vogel, Jan-Hinnerk -- Eyre, Tina -- Redmond, Seth -- Banerjee, Ruby -- Chi, Jianxiang -- Fu, Beiyuan -- Langley, Elizabeth -- Maguire, Sean F -- Laird, Gavin K -- Lloyd, David -- Kenyon, Emma -- Donaldson, Sarah -- Sehra, Harminder -- Almeida-King, Jeff -- Loveland, Jane -- Trevanion, Stephen -- Jones, Matt -- Quail, Mike -- Willey, Dave -- Hunt, Adrienne -- Burton, John -- Sims, Sarah -- McLay, Kirsten -- Plumb, Bob -- Davis, Joy -- Clee, Chris -- Oliver, Karen -- Clark, Richard -- Riddle, Clare -- Elliot, David -- Threadgold, Glen -- Harden, Glenn -- Ware, Darren -- Begum, Sharmin -- Mortimore, Beverley -- Kerry, Giselle -- Heath, Paul -- Phillimore, Benjamin -- Tracey, Alan -- Corby, Nicole -- Dunn, Matthew -- Johnson, Christopher -- Wood, Jonathan -- Clark, Susan -- Pelan, Sarah -- Griffiths, Guy -- Smith, Michelle -- Glithero, Rebecca -- Howden, Philip -- Barker, Nicholas -- Lloyd, Christine -- Stevens, Christopher -- Harley, Joanna -- Holt, Karen -- Panagiotidis, Georgios -- Lovell, Jamieson -- Beasley, Helen -- Henderson, Carl -- Gordon, Daria -- Auger, Katherine -- Wright, Deborah -- Collins, Joanna -- Raisen, Claire -- Dyer, Lauren -- Leung, Kenric -- Robertson, Lauren -- Ambridge, Kirsty -- Leongamornlert, Daniel -- McGuire, Sarah -- Gilderthorp, Ruth -- Griffiths, Coline -- Manthravadi, Deepa -- Nichol, Sarah -- Barker, Gary -- Whitehead, Siobhan -- Kay, Michael -- Brown, Jacqueline -- Murnane, Clare -- Gray, Emma -- Humphries, Matthew -- Sycamore, Neil -- Barker, Darren -- Saunders, David -- Wallis, Justene -- Babbage, Anne -- Hammond, Sian -- Mashreghi-Mohammadi, Maryam -- Barr, Lucy -- Martin, Sancha -- Wray, Paul -- Ellington, Andrew -- Matthews, Nicholas -- Ellwood, Matthew -- Woodmansey, Rebecca -- Clark, Graham -- Cooper, James D -- Tromans, Anthony -- Grafham, Darren -- Skuce, Carl -- Pandian, Richard -- Andrews, Robert -- Harrison, Elliot -- Kimberley, Andrew -- Garnett, Jane -- Fosker, Nigel -- Hall, Rebekah -- Garner, Patrick -- Kelly, Daniel -- Bird, Christine -- Palmer, Sophie -- Gehring, Ines -- Berger, Andrea -- Dooley, Christopher M -- Ersan-Urun, Zubeyde -- Eser, Cigdem -- Geiger, Horst -- Geisler, Maria -- Karotki, Lena -- Kirn, Anette -- Konantz, Judith -- Konantz, Martina -- Oberlander, Martina -- Rudolph-Geiger, Silke -- Teucke, Mathias -- Lanz, Christa -- Raddatz, Gunter -- Osoegawa, Kazutoyo -- Zhu, Baoli -- Rapp, Amanda -- Widaa, Sara -- Langford, Cordelia -- Yang, Fengtang -- Schuster, Stephan C -- Carter, Nigel P -- Harrow, Jennifer -- Ning, Zemin -- Herrero, Javier -- Searle, Steve M J -- Enright, Anton -- Geisler, Robert -- Plasterk, Ronald H A -- Lee, Charles -- Westerfield, Monte -- de Jong, Pieter J -- Zon, Leonard I -- Postlethwait, John H -- Nusslein-Volhard, Christiane -- Hubbard, Tim J P -- Roest Crollius, Hugues -- Rogers, Jane -- Stemple, Derek L -- 095908/Wellcome Trust/United Kingdom -- 098051/Wellcome Trust/United Kingdom -- 1 R01 DK55377-01A1/DK/NIDDK NIH HHS/ -- P01 HD022486/HD/NICHD NIH HHS/ -- P01 HD22486/HD/NICHD NIH HHS/ -- R01 GM085318/GM/NIGMS NIH HHS/ -- R01 OD011116/OD/NIH HHS/ -- R01 RR010715/RR/NCRR NIH HHS/ -- R01 RR020833/RR/NCRR NIH HHS/ -- England -- Nature. 2013 Apr 25;496(7446):498-503. doi: 10.1038/nature12111.

    Description: Epigenetic modifiers have fundamental roles in defining unique cellular identity through the establishment and maintenance of lineage-specific chromatin and methylation status. Several DNA modifications such as 5-hydroxymethylcytosine (5hmC) are catalysed by the ten eleven translocation (Tet) methylcytosine dioxygenase family members, and the roles of Tet proteins in regulating chromatin architecture and gene transcription independently of DNA methylation have been gradually uncovered. However, the regulation of immunity and inflammation by Tet proteins independent of their role in modulating DNA methylation remains largely unknown. Here we show that Tet2 selectively mediates active repression of interleukin-6 (IL-6) transcription during inflammation resolution in innate myeloid cells, including dendritic cells and macrophages. Loss of Tet2 resulted in the upregulation of several inflammatory mediators, including IL-6, at late phase during the response to lipopolysaccharide challenge. Tet2-deficient mice were more susceptible to endotoxin shock and dextran-sulfate-sodium-induced colitis, displaying a more severe inflammatory phenotype and increased IL-6 production compared to wild-type mice. IkappaBzeta, an IL-6-specific transcription factor, mediated specific targeting of Tet2 to the Il6 promoter, further indicating opposite regulatory roles of IkappaBzeta at initial and resolution phases of inflammation. For the repression mechanism, independent of DNA methylation and hydroxymethylation, Tet2 recruited Hdac2 and repressed transcription of Il6 via histone deacetylation. We provide mechanistic evidence for the gene-specific transcription repression activity of Tet2 via histone deacetylation and for the prevention of constant transcription activation at the chromatin level for resolving inflammation.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4697747/" 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/PMC4697747/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Zhang, Qian -- Zhao, Kai -- Shen, Qicong -- Han, Yanmei -- Gu, Yan -- Li, Xia -- Zhao, Dezhi -- Liu, Yiqi -- Wang, Chunmei -- Zhang, Xiang -- Su, Xiaoping -- Liu, Juan -- Ge, Wei -- Levine, Ross L -- Li, Nan -- Cao, Xuetao -- P30 CA008748/CA/NCI NIH HHS/ -- R01 CA173636/CA/NCI NIH HHS/ -- England -- Nature. 2015 Sep 17;525(7569):389-93. doi: 10.1038/nature15252.

    Description: Lung disease is the major cause of morbidity and mortality in cystic fibrosis, an autosomal recessive disease caused by mutations in CFTR. In cystic fibrosis, chronic infection and dysregulated neutrophilic inflammation lead to progressive airway destruction. The severity of cystic fibrosis lung disease has considerable heritability, independent of CFTR genotype. To identify genetic modifiers, here we performed a genome-wide single nucleotide polymorphism scan in one cohort of cystic fibrosis patients, replicating top candidates in an independent cohort. This approach identified IFRD1 as a modifier of cystic fibrosis lung disease severity. IFRD1 is a histone-deacetylase-dependent transcriptional co-regulator expressed during terminal neutrophil differentiation. Neutrophils, but not macrophages, from Ifrd1-deficient mice showed blunted effector function, associated with decreased NF-kappaB p65 transactivation. In vivo, IFRD1 deficiency caused delayed bacterial clearance from the airway, but also less inflammation and disease-a phenotype primarily dependent on haematopoietic cell expression, or lack of expression, of IFRD1. In humans, IFRD1 polymorphisms were significantly associated with variation in neutrophil effector function. These data indicate that IFRD1 modulates the pathogenesis of cystic fibrosis lung disease through the regulation of neutrophil effector function.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2841516/" 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/PMC2841516/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gu, YuanYuan -- Harley, Isaac T W -- Henderson, Lindsay B -- Aronow, Bruce J -- Vietor, Ilja -- Huber, Lukas A -- Harley, John B -- Kilpatrick, Jeffrey R -- Langefeld, Carl D -- Williams, Adrienne H -- Jegga, Anil G -- Chen, Jing -- Wills-Karp, Marsha -- Arshad, S Hasan -- Ewart, Susan L -- Thio, Chloe L -- Flick, Leah M -- Filippi, Marie-Dominique -- Grimes, H Leighton -- Drumm, Mitchell L -- Cutting, Garry R -- Knowles, Michael R -- Karp, Christopher L -- R01 AI024717/AI/NIAID NIH HHS/ -- R01 HL068890/HL/NHLBI NIH HHS/ -- R01 HL068890-01/HL/NHLBI NIH HHS/ -- R01 HL068927/HL/NHLBI NIH HHS/ -- R01 HL068927-01/HL/NHLBI NIH HHS/ -- R01 HL079312/HL/NHLBI NIH HHS/ -- R01 HL079312-01A1/HL/NHLBI NIH HHS/ -- R37 AI024717/AI/NIAID NIH HHS/ -- England -- Nature. 2009 Apr 23;458(7241):1039-42. doi: 10.1038/nature07811.

    Description: Gorillas are humans' closest living relatives after chimpanzees, and are of comparable importance for the study of human origins and evolution. Here we present the assembly and analysis of a genome sequence for the western lowland gorilla, and compare the whole genomes of all extant great ape genera. We propose a synthesis of genetic and fossil evidence consistent with placing the human-chimpanzee and human-chimpanzee-gorilla speciation events at approximately 6 and 10 million years ago. In 30% of the genome, gorilla is closer to human or chimpanzee than the latter are to each other; this is rarer around coding genes, indicating pervasive selection throughout great ape evolution, and has functional consequences in gene expression. A comparison of protein coding genes reveals approximately 500 genes showing accelerated evolution on each of the gorilla, human and chimpanzee lineages, and evidence for parallel acceleration, particularly of genes involved in hearing. We also compare the western and eastern gorilla species, estimating an average sequence divergence time 1.75 million years ago, but with evidence for more recent genetic exchange and a population bottleneck in the eastern species. The use of the genome sequence in these and future analyses will promote a deeper understanding of great ape biology and evolution.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3303130/" 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/PMC3303130/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Scally, Aylwyn -- Dutheil, Julien Y -- Hillier, LaDeana W -- Jordan, Gregory E -- Goodhead, Ian -- Herrero, Javier -- Hobolth, Asger -- Lappalainen, Tuuli -- Mailund, Thomas -- Marques-Bonet, Tomas -- McCarthy, Shane -- Montgomery, Stephen H -- Schwalie, Petra C -- Tang, Y Amy -- Ward, Michelle C -- Xue, Yali -- Yngvadottir, Bryndis -- Alkan, Can -- Andersen, Lars N -- Ayub, Qasim -- Ball, Edward V -- Beal, Kathryn -- Bradley, Brenda J -- Chen, Yuan -- Clee, Chris M -- Fitzgerald, Stephen -- Graves, Tina A -- Gu, Yong -- Heath, Paul -- Heger, Andreas -- Karakoc, Emre -- Kolb-Kokocinski, Anja -- Laird, Gavin K -- Lunter, Gerton -- Meader, Stephen -- Mort, Matthew -- Mullikin, James C -- Munch, Kasper -- O'Connor, Timothy D -- Phillips, Andrew D -- Prado-Martinez, Javier -- Rogers, Anthony S -- Sajjadian, Saba -- Schmidt, Dominic -- Shaw, Katy -- Simpson, Jared T -- Stenson, Peter D -- Turner, Daniel J -- Vigilant, Linda -- Vilella, Albert J -- Whitener, Weldon -- Zhu, Baoli -- Cooper, David N -- de Jong, Pieter -- Dermitzakis, Emmanouil T -- Eichler, Evan E -- Flicek, Paul -- Goldman, Nick -- Mundy, Nicholas I -- Ning, Zemin -- Odom, Duncan T -- Ponting, Chris P -- Quail, Michael A -- Ryder, Oliver A -- Searle, Stephen M -- Warren, Wesley C -- Wilson, Richard K -- Schierup, Mikkel H -- Rogers, Jane -- Tyler-Smith, Chris -- Durbin, Richard -- 062023/Wellcome Trust/United Kingdom -- 075491/Z/04/Wellcome Trust/United Kingdom -- 077009/Wellcome Trust/United Kingdom -- 077192/Wellcome Trust/United Kingdom -- 077198/Wellcome Trust/United Kingdom -- 089066/Wellcome Trust/United Kingdom -- 090532/Wellcome Trust/United Kingdom -- 095908/Wellcome Trust/United Kingdom -- 15603/Cancer Research UK/United Kingdom -- 202218/European Research Council/International -- A15603/Cancer Research UK/United Kingdom -- G0501331/Medical Research Council/United Kingdom -- G0701805/Medical Research Council/United Kingdom -- HG002385/HG/NHGRI NIH HHS/ -- U54 HG003079/HG/NHGRI NIH HHS/ -- WT062023/Wellcome Trust/United Kingdom -- WT077009/Wellcome Trust/United Kingdom -- WT077192/Wellcome Trust/United Kingdom -- WT077198/Wellcome Trust/United Kingdom -- WT089066/Wellcome Trust/United Kingdom -- Medical Research Council/United Kingdom -- Biotechnology and Biological Sciences Research Council/United Kingdom -- Howard Hughes Medical Institute/ -- Intramural NIH HHS/ -- England -- Nature. 2012 Mar 7;483(7388):169-75. doi: 10.1038/nature10842.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Wellcome Trust Sanger Institute, Wellcome Trust Genome Campus, Hinxton CB10 1SA, UK.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/22398555" target="_blank"〉PubMed〈/a〉
