    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.

    Complex landscapes of somatic rearrangement in human breast cancer genomes (2009)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2009-12-25
    Description: Multiple somatic rearrangements are often found in cancer genomes; however, the underlying processes of rearrangement and their contribution to cancer development are poorly characterized. Here we use a paired-end sequencing strategy to identify somatic rearrangements in breast cancer genomes. There are more rearrangements in some breast cancers than previously appreciated. Rearrangements are more frequent over gene footprints and most are intrachromosomal. Multiple rearrangement architectures are present, but tandem duplications are particularly common in some cancers, perhaps reflecting a specific defect in DNA maintenance. Short overlapping sequences at most rearrangement junctions indicate that these have been mediated by non-homologous end-joining DNA repair, although varying sequence patterns indicate that multiple processes of this type are operative. Several expressed in-frame fusion genes were identified but none was recurrent. The study provides a new perspective on cancer genomes, highlighting the diversity of somatic rearrangements and their potential contribution to cancer development.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3398135/" 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/PMC3398135/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Stephens, Philip J -- McBride, David J -- Lin, Meng-Lay -- Varela, Ignacio -- Pleasance, Erin D -- Simpson, Jared T -- Stebbings, Lucy A -- Leroy, Catherine -- Edkins, Sarah -- Mudie, Laura J -- Greenman, Chris D -- Jia, Mingming -- Latimer, Calli -- Teague, Jon W -- Lau, King Wai -- Burton, John -- Quail, Michael A -- Swerdlow, Harold -- Churcher, Carol -- Natrajan, Rachael -- Sieuwerts, Anieta M -- Martens, John W M -- Silver, Daniel P -- Langerod, Anita -- Russnes, Hege E G -- Foekens, John A -- Reis-Filho, Jorge S -- van 't Veer, Laura -- Richardson, Andrea L -- Borresen-Dale, Anne-Lise -- Campbell, Peter J -- Futreal, P Andrew -- Stratton, Michael R -- 077012/Z/05/Z/Wellcome Trust/United Kingdom -- 088340/Wellcome Trust/United Kingdom -- CA089393/CA/NCI NIH HHS/ -- England -- Nature. 2009 Dec 24;462(7276):1005-10. doi: 10.1038/nature08645.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Wellcome Trust Sanger Institute, Hinxton, Cambridge CB10 1SA, UK.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20033038" target="_blank"〉PubMed〈/a〉

    Secreted semaphorins control spine distribution and morphogenesis in the postnatal CNS (2009)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2009-12-17
    Description: The majority of excitatory synapses in the mammalian CNS (central nervous system) are formed on dendritic spines, and spine morphology and distribution are critical for synaptic transmission, synaptic integration and plasticity. Here, we show that a secreted semaphorin, Sema3F, is a negative regulator of spine development and synaptic structure. Mice with null mutations in genes encoding Sema3F, and its holoreceptor components neuropilin-2 (Npn-2, also known as Nrp2) and plexin A3 (PlexA3, also known as Plxna3), exhibit increased dentate gyrus (DG) granule cell (GC) and cortical layer V pyramidal neuron spine number and size, and also aberrant spine distribution. Moreover, Sema3F promotes loss of spines and excitatory synapses in dissociated neurons in vitro, and in Npn-2(-/-) brain slices cortical layer V and DG GCs exhibit increased mEPSC (miniature excitatory postsynaptic current) frequency. In contrast, a distinct Sema3A-Npn-1/PlexA4 signalling cascade controls basal dendritic arborization in layer V cortical neurons, but does not influence spine morphogenesis or distribution. These disparate effects of secreted semaphorins are reflected in the restricted dendritic localization of Npn-2 to apical dendrites and of Npn-1 (also known as Nrp1) to all dendrites of cortical pyramidal neurons. Therefore, Sema3F signalling controls spine distribution along select dendritic processes, and distinct secreted semaphorin signalling events orchestrate CNS connectivity through the differential control of spine morphogenesis, synapse formation, and the elaboration of dendritic morphology.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2842559/" 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/PMC2842559/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Tran, Tracy S -- Rubio, Maria E -- Clem, Roger L -- Johnson, Dontais -- Case, Lauren -- Tessier-Lavigne, Marc -- Huganir, Richard L -- Ginty, David D -- Kolodkin, Alex L -- F32 NS051003/NS/NINDS NIH HHS/ -- P50 MH06883/MH/NIMH NIH HHS/ -- R01 DC-006881/DC/NIDCD NIH HHS/ -- R01 MH059199/MH/NIMH NIH HHS/ -- R01 MH059199-07/MH/NIMH NIH HHS/ -- R01 MH059199-08/MH/NIMH NIH HHS/ -- R01 MH059199-09/MH/NIMH NIH HHS/ -- R01 MH059199-10/MH/NIMH NIH HHS/ -- R01 MH59199/MH/NIMH NIH HHS/ -- Howard Hughes Medical Institute/ -- England -- Nature. 2009 Dec 24;462(7276):1065-9. doi: 10.1038/nature08628.

    E2f1-3 switch from activators in progenitor cells to repressors in differentiating cells (2009)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2009-12-18
    Description: In the established model of mammalian cell cycle control, the retinoblastoma protein (Rb) functions to restrict cells from entering S phase by binding and sequestering E2f activators (E2f1, E2f2 and E2f3), which are invariably portrayed as the ultimate effectors of a transcriptional program that commit cells to enter and progress through S phase. Using a panel of tissue-specific cre-transgenic mice and conditional E2f alleles we examined the effects of E2f1, E2f2 and E2f3 triple deficiency in murine embryonic stem cells, embryos and small intestines. We show that in normal dividing progenitor cells E2f1-3 function as transcriptional activators, but contrary to the current view, are dispensable for cell division and instead are necessary for cell survival. In differentiating cells E2f1-3 function in a complex with Rb as repressors to silence E2f targets and facilitate exit from the cell cycle. The inactivation of Rb in differentiating cells resulted in a switch of E2f1-3 from repressors to activators, leading to the superactivation of E2f responsive targets and ectopic cell divisions. Loss of E2f1-3 completely suppressed these phenotypes caused by Rb deficiency. This work contextualizes the activator versus repressor functions of E2f1-3 in vivo, revealing distinct roles in dividing versus differentiating cells and in normal versus cancer-like cell cycles.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2806193/" 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/PMC2806193/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Chong, Jean-Leon -- Wenzel, Pamela L -- Saenz-Robles, M Teresa -- Nair, Vivek -- Ferrey, Antoney -- Hagan, John P -- Gomez, Yorman M -- Sharma, Nidhi -- Chen, Hui-Zi -- Ouseph, Madhu -- Wang, Shu-Huei -- Trikha, Prashant -- Culp, Brian -- Mezache, Louise -- Winton, Douglas J -- Sansom, Owen J -- Chen, Danian -- Bremner, Rod -- Cantalupo, Paul G -- Robinson, Michael L -- Pipas, James M -- Leone, Gustavo -- 5 T32 CA106196-04/CA/NCI NIH HHS/ -- CA098956/CA/NCI NIH HHS/ -- P01CA097189/CA/NCI NIH HHS/ -- R01 CA098956/CA/NCI NIH HHS/ -- R01 CA098956-06A2/CA/NCI NIH HHS/ -- R01CA82259/CA/NCI NIH HHS/ -- R01CA85619/CA/NCI NIH HHS/ -- R01HD04470/HD/NICHD NIH HHS/ -- England -- Nature. 2009 Dec 17;462(7275):930-4. doi: 10.1038/nature08677.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Molecular Virology, Immunology and Medical Genetics, College of Medicine, The Ohio State University, Columbus, Ohio 43210, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20016602" target="_blank"〉PubMed〈/a〉

    Cancer-associated IDH1 mutations produce 2-hydroxyglutarate (2009)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2009-11-26
    Description: Mutations in the enzyme cytosolic isocitrate dehydrogenase 1 (IDH1) are a common feature of a major subset of primary human brain cancers. These mutations occur at a single amino acid residue of the IDH1 active site, resulting in loss of the enzyme's ability to catalyse conversion of isocitrate to alpha-ketoglutarate. However, only a single copy of the gene is mutated in tumours, raising the possibility that the mutations do not result in a simple loss of function. Here we show that cancer-associated IDH1 mutations result in a new ability of the enzyme to catalyse the NADPH-dependent reduction of alpha-ketoglutarate to R(-)-2-hydroxyglutarate (2HG). Structural studies demonstrate that when arginine 132 is mutated to histidine, residues in the active site are shifted to produce structural changes consistent with reduced oxidative decarboxylation of isocitrate and acquisition of the ability to convert alpha-ketoglutarate to 2HG. Excess accumulation of 2HG has been shown to lead to an elevated risk of malignant brain tumours in patients with inborn errors of 2HG metabolism. Similarly, in human malignant gliomas harbouring IDH1 mutations, we find markedly elevated levels of 2HG. These data demonstrate that the IDH1 mutations result in production of the onco-metabolite 2HG, and indicate that the excess 2HG which accumulates in vivo contributes to the formation and malignant progression of gliomas.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2818760/" 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/PMC2818760/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Dang, Lenny -- White, David W -- Gross, Stefan -- Bennett, Bryson D -- Bittinger, Mark A -- Driggers, Edward M -- Fantin, Valeria R -- Jang, Hyun Gyung -- Jin, Shengfang -- Keenan, Marie C -- Marks, Kevin M -- Prins, Robert M -- Ward, Patrick S -- Yen, Katharine E -- Liau, Linda M -- Rabinowitz, Joshua D -- Cantley, Lewis C -- Thompson, Craig B -- Vander Heiden, Matthew G -- Su, Shinsan M -- P01 CA104838/CA/NCI NIH HHS/ -- P01 CA104838-05/CA/NCI NIH HHS/ -- P30 EB009998/EB/NIBIB NIH HHS/ -- R01 CA105463/CA/NCI NIH HHS/ -- R01 CA105463-06/CA/NCI NIH HHS/ -- R21 CA128620/CA/NCI NIH HHS/ -- England -- Nature. 2009 Dec 10;462(7274):739-44. doi: 10.1038/nature08617.

    Genetic variation in IL28B and spontaneous clearance of hepatitis C virus (2009)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2009-09-18
    Description: Hepatitis C virus (HCV) infection is the most common blood-borne infection in the United States, with estimates of 4 million HCV-infected individuals in the United States and 170 million worldwide. Most (70-80%) HCV infections persist and about 30% of individuals with persistent infection develop chronic liver disease, including cirrhosis and hepatocellular carcinoma. Epidemiological, viral and host factors have been associated with the differences in HCV clearance or persistence, and studies have demonstrated that a strong host immune response against HCV favours viral clearance. Thus, variation in genes involved in the immune response may contribute to the ability to clear the virus. In a recent genome-wide association study, a single nucleotide polymorphism (rs12979860) 3 kilobases upstream of the IL28B gene, which encodes the type III interferon IFN-3, was shown to associate strongly with more than a twofold difference in response to HCV drug treatment. To determine the potential effect of rs12979860 variation on outcome to HCV infection in a natural history setting, we genotyped this variant in HCV cohorts comprised of individuals who spontaneously cleared the virus (n = 388) or had persistent infection (n = 620). We show that the C/C genotype strongly enhances resolution of HCV infection among individuals of both European and African ancestry. To our knowledge, this is the strongest and most significant genetic effect associated with natural clearance of HCV, and these results implicate a primary role for IL28B in resolution of HCV infection.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3172006/" 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/PMC3172006/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Thomas, David L -- Thio, Chloe L -- Martin, Maureen P -- Qi, Ying -- Ge, Dongliang -- O'Huigin, Colm -- Kidd, Judith -- Kidd, Kenneth -- Khakoo, Salim I -- Alexander, Graeme -- Goedert, James J -- Kirk, Gregory D -- Donfield, Sharyne M -- Rosen, Hugo R -- Tobler, Leslie H -- Busch, Michael P -- McHutchison, John G -- Goldstein, David B -- Carrington, Mary -- HHSN261200800001E/CO/NCI NIH HHS/ -- HHSN261200800001E/PHS HHS/ -- R01 DA004334/DA/NIDA NIH HHS/ -- R01DA004334/DA/NIDA NIH HHS/ -- R01DA013324/DA/NIDA NIH HHS/ -- R01DK60590/DK/NIDDK NIH HHS/ -- R01HD41224/HD/NICHD NIH HHS/ -- R01HL076902/HL/NHLBI NIH HHS/ -- R56 DA004334/DA/NIDA NIH HHS/ -- Intramural NIH HHS/ -- England -- Nature. 2009 Oct 8;461(7265):798-801. doi: 10.1038/nature08463.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Johns Hopkins University, Division of Infectious Diseases, Baltimore, Maryland 21205, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19759533" target="_blank"〉PubMed〈/a〉

    iPS cells produce viable mice through tetraploid complementation (2009)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2009-08-13
    Description: Since the initial description of induced pluripotent stem (iPS) cells created by forced expression of four transcription factors in mouse fibroblasts, the technique has been used to generate embryonic stem (ES)-cell-like pluripotent cells from a variety of cell types in other species, including primates and rat. It has become a popular means to reprogram somatic genomes into an embryonic-like pluripotent state, and a preferred alternative to somatic-cell nuclear transfer and somatic-cell fusion with ES cells. However, iPS cell reprogramming remains slow and inefficient. Notably, no live animals have been produced by the most stringent tetraploid complementation assay, indicative of a failure to create fully pluripotent cells. Here we report the generation of several iPS cell lines that are capable of generating viable, fertile live-born progeny by tetraploid complementation. These iPS cells maintain a pluripotent potential that is very close to ES cells generated from in vivo or nuclear transfer embryos. We demonstrate the practicality of using iPS cells as useful tools for the characterization of cellular reprogramming and developmental potency, and confirm that iPS cells can attain true pluripotency that is similar to that of ES cells.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Zhao, Xiao-yang -- Li, Wei -- Lv, Zhuo -- Liu, Lei -- Tong, Man -- Hai, Tang -- Hao, Jie -- Guo, Chang-long -- Ma, Qing-wen -- Wang, Liu -- Zeng, Fanyi -- Zhou, Qi -- England -- Nature. 2009 Sep 3;461(7260):86-90. doi: 10.1038/nature08267.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉State Key Laboratory of Reproductive Biology, Institute of Zoology, Chinese Academy of Sciences, Beijing 100101, China.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19672241" target="_blank"〉PubMed〈/a〉

    GOLPH3 modulates mTOR signalling and rapamycin sensitivity in cancer (2009)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2009-06-26
    Description: Genome-wide copy number analyses of human cancers identified a frequent 5p13 amplification in several solid tumour types, including lung (56%), ovarian (38%), breast (32%), prostate (37%) and melanoma (32%). Here, using integrative analysis of a genomic profile of the region, we identify a Golgi protein, GOLPH3, as a candidate targeted for amplification. Gain- and loss-of-function studies in vitro and in vivo validated GOLPH3 as a potent oncogene. Physically, GOLPH3 localizes to the trans-Golgi network and interacts with components of the retromer complex, which in yeast has been linked to target of rapamycin (TOR) signalling. Mechanistically, GOLPH3 regulates cell size, enhances growth-factor-induced mTOR (also known as FRAP1) signalling in human cancer cells, and alters the response to an mTOR inhibitor in vivo. Thus, genomic and genetic, biological, functional and biochemical data in yeast and humans establishes GOLPH3 as a new oncogene that is commonly targeted for amplification in human cancer, and is capable of modulating the response to rapamycin, a cancer drug in clinical use.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2753613/" 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/PMC2753613/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Scott, Kenneth L -- Kabbarah, Omar -- Liang, Mei-Chih -- Ivanova, Elena -- Anagnostou, Valsamo -- Wu, Joyce -- Dhakal, Sabin -- Wu, Min -- Chen, Shujuan -- Feinberg, Tamar -- Huang, Joseph -- Saci, Abdel -- Widlund, Hans R -- Fisher, David E -- Xiao, Yonghong -- Rimm, David L -- Protopopov, Alexei -- Wong, Kwok-Kin -- Chin, Lynda -- 5-T32-AR07098-31/AR/NIAMS NIH HHS/ -- P50 CA090578/CA/NCI NIH HHS/ -- P50 CA093683/CA/NCI NIH HHS/ -- P50 CA093683-06A20011/CA/NCI NIH HHS/ -- P50 CA93683/CA/NCI NIH HHS/ -- R0-1 CA 114277/CA/NCI NIH HHS/ -- R01 AG2400401/AG/NIA NIH HHS/ -- R01 CA093947/CA/NCI NIH HHS/ -- R01 CA093947-08/CA/NCI NIH HHS/ -- R01 CA114277/CA/NCI NIH HHS/ -- R01 CA114277-04/CA/NCI NIH HHS/ -- R01 CA122794/CA/NCI NIH HHS/ -- R01 CA122794-03/CA/NCI NIH HHS/ -- R01 CA93947/CA/NCI NIH HHS/ -- T32 AR007098/AR/NIAMS NIH HHS/ -- T32 AR007098-32/AR/NIAMS NIH HHS/ -- England -- Nature. 2009 Jun 25;459(7250):1085-90. doi: 10.1038/nature08109.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Medical Oncology, Dana-Farber Cancer Institute, Boston, Massachusetts, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19553991" target="_blank"〉PubMed〈/a〉

    Bmi1 regulates mitochondrial function and the DNA damage response pathway (2009)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2009-05-01
    Description: Mice deficient in the Polycomb repressor Bmi1 develop numerous abnormalities including a severe defect in stem cell self-renewal, alterations in thymocyte maturation and a shortened lifespan. Previous work has implicated de-repression of the Ink4a/Arf (also known as Cdkn2a) locus as mediating many of the aspects of the Bmi1(-/-) phenotype. Here we demonstrate that cells derived from Bmi1(-/-) mice also have impaired mitochondrial function, a marked increase in the intracellular levels of reactive oxygen species and subsequent engagement of the DNA damage response pathway. Furthermore, many of the deficiencies normally observed in Bmi1(-/-) mice improve after either pharmacological treatment with the antioxidant N-acetylcysteine or genetic disruption of the DNA damage response pathway by Chk2 (also known as Chek2) deletion. These results demonstrate that Bmi1 has an unexpected role in maintaining mitochondrial function and redox homeostasis and indicate that the Polycomb family of proteins can coordinately regulate cellular metabolism with stem and progenitor cell function.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4721521/" 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/PMC4721521/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Liu, Jie -- Cao, Liu -- Chen, Jichun -- Song, Shiwei -- Lee, In Hye -- Quijano, Celia -- Liu, Hongjun -- Keyvanfar, Keyvan -- Chen, Haoqian -- Cao, Long-Yue -- Ahn, Bong-Hyun -- Kumar, Neil G -- Rovira, Ilsa I -- Xu, Xiao-Ling -- van Lohuizen, Maarten -- Motoyama, Noboru -- Deng, Chu-Xia -- Finkel, Toren -- R00 AG032356/AG/NIA NIH HHS/ -- Z01 HL005012-11/Intramural NIH HHS/ -- Howard Hughes Medical Institute/ -- England -- Nature. 2009 May 21;459(7245):387-92. doi: 10.1038/nature08040.

    Reconstructing Indian population history (2009)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2009-09-26
    Description: India has been underrepresented in genome-wide surveys of human variation. We analyse 25 diverse groups in India to provide strong evidence for two ancient populations, genetically divergent, that are ancestral to most Indians today. One, the 'Ancestral North Indians' (ANI), is genetically close to Middle Easterners, Central Asians, and Europeans, whereas the other, the 'Ancestral South Indians' (ASI), is as distinct from ANI and East Asians as they are from each other. By introducing methods that can estimate ancestry without accurate ancestral populations, we show that ANI ancestry ranges from 39-71% in most Indian groups, and is higher in traditionally upper caste and Indo-European speakers. Groups with only ASI ancestry may no longer exist in mainland India. However, the indigenous Andaman Islanders are unique in being ASI-related groups without ANI ancestry. Allele frequency differences between groups in India are larger than in Europe, reflecting strong founder effects whose signatures have been maintained for thousands of years owing to endogamy. We therefore predict that there will be an excess of recessive diseases in India, which should be possible to screen and map genetically.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2842210/" 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/PMC2842210/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Reich, David -- Thangaraj, Kumarasamy -- Patterson, Nick -- Price, Alkes L -- Singh, Lalji -- HG004168/HG/NHGRI NIH HHS/ -- R01 HG006399/HG/NHGRI NIH HHS/ -- U01 HG004168/HG/NHGRI NIH HHS/ -- U01 HG004168-03/HG/NHGRI NIH HHS/ -- England -- Nature. 2009 Sep 24;461(7263):489-94. doi: 10.1038/nature08365.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Genetics, Harvard Medical School, Boston, Massachusetts 02115, USA. reich@genetics.med.harvard.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19779445" target="_blank"〉PubMed〈/a〉
