    Description: Global patterns of human DNA sequence variation (haplotypes) defined by common single nucleotide polymorphisms (SNPs) have important implications for identifying disease associations and human traits. We have used high-density oligonucleotide arrays, in combination with somatic cell genetics, to identify a large fraction of all common human chromosome 21 SNPs and to directly observe the haplotype structure defined by these SNPs. This structure reveals blocks of limited haplotype diversity in which more than 80% of a global human sample can typically be characterized by only three common haplotypes.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Patil, N -- Berno, A J -- Hinds, D A -- Barrett, W A -- Doshi, J M -- Hacker, C R -- Kautzer, C R -- Lee, D H -- Marjoribanks, C -- McDonough, D P -- Nguyen, B T -- Norris, M C -- Sheehan, J B -- Shen, N -- Stern, D -- Stokowski, R P -- Thomas, D J -- Trulson, M O -- Vyas, K R -- Frazer, K A -- Fodor, S P -- Cox, D R -- New York, N.Y. -- Science. 2001 Nov 23;294(5547):1719-23.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Perlegen Sciences, Inc., 2021 Stierlin Court, Mountain View, CA 94043, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/11721056" target="_blank"〉PubMed〈/a〉

    Description: Chemokine receptors serve as portals of entry for certain intracellular pathogens, most notably human immunodeficiency virus (HIV). Myxoma virus is a member of the poxvirus family that induces a lethal systemic disease in rabbits, but no poxvirus receptor has ever been defined. Rodent fibroblasts (3T3) that cannot be infected with myxoma virus could be made fully permissive for myxoma virus infection by expression of any one of several human chemokine receptors, including CCR1, CCR5, and CXCR4. Conversely, infection of 3T3-CCR5 cells can be inhibited by RANTES, anti-CCR5 polyclonal antibody, or herbimycin A but not by monoclonal antibodies that block HIV-1 infection or by pertussis toxin. These findings suggest that poxviruses, like HIV, are able to use chemokine receptors to infect specific cell subtypes, notably migratory leukocytes, but that their mechanisms of receptor interactions are distinct.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lalani, A S -- Masters, J -- Zeng, W -- Barrett, J -- Pannu, R -- Everett, H -- Arendt, C W -- McFadden, G -- New York, N.Y. -- Science. 1999 Dec 3;286(5446):1968-71.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉The John P.

    Description: Two families of small peptides that bind to the human thrombopoietin receptor and compete with the binding of the natural ligand thrombopoietin (TPO) were identified from recombinant peptide libraries. The sequences of these peptides were not found in the primary sequence of TPO. Screening libraries of variants of one of these families under affinity-selective conditions yielded a 14-amino acid peptide (Ile-Glu-Gly-Pro-Thr-Leu-Arg-Gln-Trp-Leu-Ala-Ala-Arg-Ala) with high affinity (dissociation constant approximately 2 nanomolar) that stimulates the proliferation of a TPO-responsive Ba/F3 cell line with a median effective concentration (EC50) of 400 nanomolar. Dimerization of this peptide by a carboxyl-terminal linkage to a lysine branch produced a compound with an EC50 of 100 picomolar, which was equipotent to the 332-amino acid natural cytokine in cell-based assays. The peptide dimer also stimulated the in vitro proliferation and maturation of megakaryocytes from human bone marrow cells and promoted an increase in platelet count when administered to normal mice.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Cwirla, S E -- Balasubramanian, P -- Duffin, D J -- Wagstrom, C R -- Gates, C M -- Singer, S C -- Davis, A M -- Tansik, R L -- Mattheakis, L C -- Boytos, C M -- Schatz, P J -- Baccanari, D P -- Wrighton, N C -- Barrett, R W -- Dower, W J -- New York, N.Y. -- Science. 1997 Jun 13;276(5319):1696-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Affymax Research Institute, 4001 Miranda Avenue, Palo Alto, CA 94304, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9180079" target="_blank"〉PubMed〈/a〉

    Description: The Sir2 deacetylase regulates chromatin silencing and lifespan in Saccharomyces cerevisiae. In mice, deficiency for the Sir2 family member SIRT6 leads to a shortened lifespan and a premature ageing-like phenotype. However, the molecular mechanisms of SIRT6 function are unclear. SIRT6 is a chromatin-associated protein, but no enzymatic activity of SIRT6 at chromatin has yet been detected, and the identity of physiological SIRT6 substrates is unknown. Here we show that the human SIRT6 protein is an NAD+-dependent, histone H3 lysine 9 (H3K9) deacetylase that modulates telomeric chromatin. SIRT6 associates specifically with telomeres, and SIRT6 depletion leads to telomere dysfunction with end-to-end chromosomal fusions and premature cellular senescence. Moreover, SIRT6-depleted cells exhibit abnormal telomere structures that resemble defects observed in Werner syndrome, a premature ageing disorder. At telomeric chromatin, SIRT6 deacetylates H3K9 and is required for the stable association of WRN, the factor that is mutated in Werner syndrome. We propose that SIRT6 contributes to the propagation of a specialized chromatin state at mammalian telomeres, which in turn is required for proper telomere metabolism and function. Our findings constitute the first identification of a physiological enzymatic activity of SIRT6, and link chromatin regulation by SIRT6 to telomere maintenance and a human premature ageing syndrome.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2646112/" 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/PMC2646112/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Michishita, Eriko -- McCord, Ronald A -- Berber, Elisabeth -- Kioi, Mitomu -- Padilla-Nash, Hesed -- Damian, Mara -- Cheung, Peggie -- Kusumoto, Rika -- Kawahara, Tiara L A -- Barrett, J Carl -- Chang, Howard Y -- Bohr, Vilhelm A -- Ried, Thomas -- Gozani, Or -- Chua, Katrin F -- K08 AG028961/AG/NIA NIH HHS/ -- K08 AG028961-03/AG/NIA NIH HHS/ -- R01 AG028867/AG/NIA NIH HHS/ -- R01 AG028867-03/AG/NIA NIH HHS/ -- R01 GM079641/GM/NIGMS NIH HHS/ -- R01 GM079641-02/GM/NIGMS NIH HHS/ -- England -- Nature. 2008 Mar 27;452(7186):492-6. doi: 10.1038/nature06736.

    Description: The control of cellular senescence by specific human chromosomes was examined in interspecies cell hybrids between diploid human fibroblasts and an immortal, Syrian hamster cell line. Most such hybrids exhibited a limited life span comparable to that of the human fibroblasts, indicating that cellular senescence is dominant in these hybrids. Karyotypic analyses of the hybrid clones that did not senesce revealed that all these clones had lost both copies of human chromosome 1, whereas all other human chromosomes were observed in at least some of the immortal hybrids. The application of selective pressure for retention of human chromosome 1 to the cell hybrids resulted in an increased percentage of hybrids that senesced. Further, the introduction of a single copy of human chromosome 1 to the hamster cells by microcell fusion caused typical signs of cellular senescence. Transfer of chromosome 11 had no effect on the growth of the cells. These findings indicate that human chromosome 1 may participate in the control of cellular senescence and further support a genetic basis for cellular senescence.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Sugawara, O -- Oshimura, M -- Koi, M -- Annab, L A -- Barrett, J C -- New York, N.Y. -- Science. 1990 Feb 9;247(4943):707-10.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉National Institute of Environmental Health Sciences, National Institutes of Health, Research Triangle Park, NC 27709.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2300822" target="_blank"〉PubMed〈/a〉

    Description: Obesity is a serious international health problem that increases the risk of several common diseases. The genetic factors predisposing to obesity are poorly understood. A genome-wide search for type 2 diabetes-susceptibility genes identified a common variant in the FTO (fat mass and obesity associated) gene that predisposes to diabetes through an effect on body mass index (BMI). An additive association of the variant with BMI was replicated in 13 cohorts with 38,759 participants. The 16% of adults who are homozygous for the risk allele weighed about 3 kilograms more and had 1.67-fold increased odds of obesity when compared with those not inheriting a risk allele. This association was observed from age 7 years upward and reflects a specific increase in fat mass.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2646098/" 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/PMC2646098/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Frayling, Timothy M -- Timpson, Nicholas J -- Weedon, Michael N -- Zeggini, Eleftheria -- Freathy, Rachel M -- Lindgren, Cecilia M -- Perry, John R B -- Elliott, Katherine S -- Lango, Hana -- Rayner, Nigel W -- Shields, Beverley -- Harries, Lorna W -- Barrett, Jeffrey C -- Ellard, Sian -- Groves, Christopher J -- Knight, Bridget -- Patch, Ann-Marie -- Ness, Andrew R -- Ebrahim, Shah -- Lawlor, Debbie A -- Ring, Susan M -- Ben-Shlomo, Yoav -- Jarvelin, Marjo-Riitta -- Sovio, Ulla -- Bennett, Amanda J -- Melzer, David -- Ferrucci, Luigi -- Loos, Ruth J F -- Barroso, Ines -- Wareham, Nicholas J -- Karpe, Fredrik -- Owen, Katharine R -- Cardon, Lon R -- Walker, Mark -- Hitman, Graham A -- Palmer, Colin N A -- Doney, Alex S F -- Morris, Andrew D -- Smith, George Davey -- Hattersley, Andrew T -- McCarthy, Mark I -- 079557/Wellcome Trust/United Kingdom -- 090532/Wellcome Trust/United Kingdom -- G0000934/Medical Research Council/United Kingdom -- G0500070/Medical Research Council/United Kingdom -- G0600705/Medical Research Council/United Kingdom -- G9815508/Medical Research Council/United Kingdom -- MC_U106179471/Medical Research Council/United Kingdom -- MC_U106188470/Medical Research Council/United Kingdom -- Z99 AG999999/Intramural NIH HHS/ -- Wellcome Trust/United Kingdom -- New York, N.Y. -- Science. 2007 May 11;316(5826):889-94.

    Description: Food security is a growing concern worldwide. More than 1 billion people are estimated to lack sufficient dietary energy availability, and at least twice that number suffer micronutrient deficiencies. Because indicators inform action, much current research focuses on improving food insecurity measurement. Yet estimated prevalence rates and patterns remain tenuous because measuring food security, an elusive concept, remains difficult.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Barrett, Christopher B -- New York, N.Y. -- Science. 2010 Feb 12;327(5967):825-8. doi: 10.1126/science.1182768.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Applied Economics and Management, Warren Hall, Cornell University, Ithaca, NY 14853-7801, USA. cbb2@cornell.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20150491" target="_blank"〉PubMed〈/a〉
