    Reconstructing Native American population history (2012)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2012-07-18
    Description: The peopling of the Americas has been the subject of extensive genetic, archaeological and linguistic research; however, central questions remain unresolved. One contentious issue is whether the settlement occurred by means of a single migration or multiple streams of migration from Siberia. The pattern of dispersals within the Americas is also poorly understood. To address these questions at a higher resolution than was previously possible, we assembled data from 52 Native American and 17 Siberian groups genotyped at 364,470 single nucleotide polymorphisms. Here we show that Native Americans descend from at least three streams of Asian gene flow. Most descend entirely from a single ancestral population that we call 'First American'. However, speakers of Eskimo-Aleut languages from the Arctic inherit almost half their ancestry from a second stream of Asian gene flow, and the Na-Dene-speaking Chipewyan from Canada inherit roughly one-tenth of their ancestry from a third stream. We show that the initial peopling followed a southward expansion facilitated by the coast, with sequential population splits and little gene flow after divergence, especially in South America. A major exception is in Chibchan speakers on both sides of the Panama isthmus, who have ancestry from both North and South America.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3615710/" 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/PMC3615710/" 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 -- Patterson, Nick -- Campbell, Desmond -- Tandon, Arti -- Mazieres, Stephane -- Ray, Nicolas -- Parra, Maria V -- Rojas, Winston -- Duque, Constanza -- Mesa, Natalia -- Garcia, Luis F -- Triana, Omar -- Blair, Silvia -- Maestre, Amanda -- Dib, Juan C -- Bravi, Claudio M -- Bailliet, Graciela -- Corach, Daniel -- Hunemeier, Tabita -- Bortolini, Maria Catira -- Salzano, Francisco M -- Petzl-Erler, Maria Luiza -- Acuna-Alonzo, Victor -- Aguilar-Salinas, Carlos -- Canizales-Quinteros, Samuel -- Tusie-Luna, Teresa -- Riba, Laura -- Rodriguez-Cruz, Maricela -- Lopez-Alarcon, Mardia -- Coral-Vazquez, Ramon -- Canto-Cetina, Thelma -- Silva-Zolezzi, Irma -- Fernandez-Lopez, Juan Carlos -- Contreras, Alejandra V -- Jimenez-Sanchez, Gerardo -- Gomez-Vazquez, Maria Jose -- Molina, Julio -- Carracedo, Angel -- Salas, Antonio -- Gallo, Carla -- Poletti, Giovanni -- Witonsky, David B -- Alkorta-Aranburu, Gorka -- Sukernik, Rem I -- Osipova, Ludmila -- Fedorova, Sardana A -- Vasquez, Rene -- Villena, Mercedes -- Moreau, Claudia -- Barrantes, Ramiro -- Pauls, David -- Excoffier, Laurent -- Bedoya, Gabriel -- Rothhammer, Francisco -- Dugoujon, Jean-Michel -- Larrouy, Georges -- Klitz, William -- Labuda, Damian -- Kidd, Judith -- Kidd, Kenneth -- Di Rienzo, Anna -- Freimer, Nelson B -- Price, Alkes L -- Ruiz-Linares, Andres -- BB/1021213/1/Biotechnology and Biological Sciences Research Council/United Kingdom -- GM057672/GM/NIGMS NIH HHS/ -- GM079558/GM/NIGMS NIH HHS/ -- GM079558-S1/GM/NIGMS NIH HHS/ -- HG006399/HG/NHGRI NIH HHS/ -- MH075007/MH/NIMH NIH HHS/ -- NS037484/NS/NINDS NIH HHS/ -- NS043538/NS/NINDS NIH HHS/ -- R01 GM079558/GM/NIGMS NIH HHS/ -- R01 GM100233/GM/NIGMS NIH HHS/ -- R01 HG006399/HG/NHGRI NIH HHS/ -- R21 DK073818/DK/NIDDK NIH HHS/ -- Canadian Institutes of Health Research/Canada -- England -- Nature. 2012 Aug 16;488(7411):370-4. doi: 10.1038/nature11258.〈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/22801491" target="_blank"〉PubMed〈/a〉

    AIDS-Kaposi's sarcoma-derived cells express cytokines with autocrine and paracrine growth effects (1989)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1989-01-13
    Description: When grown in vitro, cells from Kaposi's sarcoma lesions of AIDS patients (AIDS-KS cells) constitutively release several growth promoting activities. When inoculated into nude mice, the AIDS-KS cells induce a KS-like lesion of mouse origin. Here it is shown that the AIDS-KS cells express messenger RNA for a complex mixture of cytokines that correlate with several of the biological activities of these cells. Basic fibroblast growth factor, which is a potent angiogenic factor, and interleukin-1 messenger RNAs are expressed at very high levels and seem to account for a large proportion of the activities, since their corresponding proteins are released in biologically active form into the culture media where they induce autocrine and paracrine growth effects.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ensoli, B -- Nakamura, S -- Salahuddin, S Z -- Biberfeld, P -- Larsson, L -- Beaver, B -- Wong-Staal, F -- Gallo, R C -- New York, N.Y. -- Science. 1989 Jan 13;243(4888):223-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratory of Tumor Cell Biology, National Cancer Institute, Bethesda, MD 20892.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2643161" target="_blank"〉PubMed〈/a〉

    Identification of RANTES, MIP-1 alpha, and MIP-1 beta as the major HIV-suppressive factors produced by CD8+ T cells (1995)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1995-12-15
    Description: Evidence suggests that CD8+ T lymphocytes are involved in the control of human immunodeficiency virus (HIV) infection in vivo, either by cytolytic mechanisms or by the release of HIV-suppressive factors (HIV-SF). The chemokines RANTES, MIP-1 alpha, and MIP-1 beta were identified as the major HIV-SF produced by CD8+ T cells. Two active proteins purified from the culture supernatant of an immortalized CD8+ T cell clone revealed sequence identity with human RANTES and MIP-1 alpha. RANTES, MIP-1 alpha, and MIP-1 beta were released by both immortalized and primary CD8+ T cells. HIV-SF activity produced by these cells was completely blocked by a combination of neutralizing antibodies against RANTES, MIP-1 alpha, and MIP-1 beta. Recombinant human RANTES, MIP-1 alpha, and MIP-1 beta induced a dose-dependent inhibition of different strains of HIV-1, HIV-2, and simian immunodeficiency virus (SIV). These data may have relevance for the prevention and therapy of AIDS.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Cocchi, F -- DeVico, A L -- Garzino-Demo, A -- Arya, S K -- Gallo, R C -- Lusso, P -- New York, N.Y. -- Science. 1995 Dec 15;270(5243):1811-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratory of Tumor Cell Biology, National Cancer Institute, Bethesda, MD 20892, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8525373" target="_blank"〉PubMed〈/a〉

    Hydroxyurea as an inhibitor of human immunodeficiency virus-type 1 replication (1994)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1994-11-04
    Description: Hydroxyurea, a drug widely used in therapy of several human diseases, inhibits deoxynucleotide synthesis--and, consequently, DNA synthesis--by blocking the cellular enzyme ribonucleotide reductase. Hydroxyurea inhibits human immunodeficiency virus-type 1 (HIV-1) DNA synthesis in activated peripheral blood lymphocytes by decreasing the amount of intracellular deoxynucleotides, thus suggesting that this drug has an antiviral effect. Hydroxyurea has now been shown to block HIV-1 replication in acutely infected primary human lymphocytes (quiescent and activated) and macrophages, as well as in blood cells infected in vivo obtained from individuals with acquired immunodeficiency syndrome (AIDS). The antiviral effect was achieved at nontoxic doses of hydroxyurea, lower than those currently used in human therapy. Combination of hydroxyurea with the nucleoside analog didanosine (2',3'-dideoxyinosine, or ddl) generated a synergistic inhibitory effect without increasing toxicity. In some instances, inhibition of HIV-1 by hydroxyurea was irreversible, even several weeks after suspension of drug treatment. The indirect inhibition of HIV-1 by hydroxyurea is not expected to generate high rates of escape mutants. Hydroxyurea therefore appears to be a possible candidate for AIDS therapy.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lori, F -- Malykh, A -- Cara, A -- Sun, D -- Weinstein, J N -- Lisziewicz, J -- Gallo, R C -- New York, N.Y. -- Science. 1994 Nov 4;266(5186):801-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratory of Tumor Cell Biology, National Cancer Institute, National Institutes of Health, Bethesda, MD 20892-4255.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7973634" target="_blank"〉PubMed〈/a〉

    Identification of a major growth factor for AIDS-Kaposi's sarcoma cells as oncostatin M (1992)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1992-03-13
    Description: Conditioned medium from human T cell leukemia virus type 2 (HTLV-II)-infected T cells supports the growth and long-term culture of cells derived from acquired immunodeficiency syndrome (AIDS)-associated Kaposi's sarcoma lesions (AIDS-KS cells). A protein of 30 kilodaltons was purified from conditioned medium that supports the growth of AIDS-KS cells. The amino-terminal sequence of this protein was identical to the amino-terminal sequence of Oncostatin M, a glycoprotein that inhibits the growth of a variety of cancer cells. Oncostatin M from conditioned medium stimulated a twofold increase in the growth of AIDS-KS cells at a concentration of less than 1 nanogram of the protein per milliliter of medium.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Nair, B C -- DeVico, A L -- Nakamura, S -- Copeland, T D -- Chen, Y -- Patel, A -- O'Neil, T -- Oroszlan, S -- Gallo, R C -- Sarngadharan, M G -- N01-CO-74101/CO/NCI NIH HHS/ -- N01-CP-73723/CP/NCI NIH HHS/ -- New York, N.Y. -- Science. 1992 Mar 13;255(5050):1430-2.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Cell Biology, Advanced BioScience Laboratories, Inc., Kensington, MD.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1542792" target="_blank"〉PubMed〈/a〉

    Inhibition of development of Kaposi's sarcoma-related lesions by a bacterial cell wall complex (1992)

    Details
    Publication Date: 1992-03-13
    Description: In vitro and in vivo model systems for the study of human immunodeficiency virus (HIV)-associated Kaposi's sarcoma (KS) were used to evaluate compounds for their potential as therapeutic agents. A sulfated polysaccharide-peptidoglycan compound (SP-PG) produced by bacteria controlled the in vitro growth of acquired immunodeficiency syndrome (AIDS)-associated, KS-derived spindle-shaped cells (AIDS-KS cells) at noncytotoxic concentrations. Angiogenesis induced by AIDS-KS cells in the chicken chorioallantoic membrane assay was blocked by SP-PG, which also inhibited the vascular hyperpermeability response and the angiogenesis associated with the induction of KS-like lesions that develop after subcutaneous inoculation of AIDS-KS cells into nude mice. Suramin, pentosan polysulfate, and interferon alpha, which are currently in use for therapy of KS, were either less effective than SP-PG or much more cytotoxic, or both.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Nakamura, S -- Sakurada, S -- Salahuddin, S Z -- Osada, Y -- Tanaka, N G -- Sakamoto, N -- Sekiguchi, M -- Gallo, R C -- New York, N.Y. -- Science. 1992 Mar 13;255(5050):1437-40.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Internal Medicine, University of Southern California, Los Angeles 90033.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1371891" target="_blank"〉PubMed〈/a〉

    Kaposi's sarcoma cells: long-term culture with growth factor from retrovirus-infected CD4+ T cells (1988)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1988-10-21
    Description: Studies of the biology and pathogenesis of Kaposi's sarcoma (KS) have been hampered by the inability to maintain long-term cultures of KS cells in vitro. In this study AIDS-KS-derived cells with characteristic spindle-like morphology were cultured with a growth factor (or factors) released by CD4+ T lymphocytes infected with human T-lymphotropic virus type I or II (HTLV-I or HTLV-II) or with human immunodeficiency virus type 1 or 2 (HIV-1 or HIV-2). Medium conditioned by HTLV-II-infected, transformed lines of T cells (HTLV-II CM) contained large amounts of this growth activity and also supported the temporary growth of normal vascular endothelial cells, but not fibroblasts. Interleukin-1 and tumor necrosis factor-alpha stimulated the growth of the KS-derived cells, but the growth was only transient and these could be distinguished from that in HTLV-II CM. Other known endothelial cell growth promoting factors, such as acidic and basic fibroblast growth factors and epidermal growth factor, did not support the long-term growth of the AIDS-KS cells. The factor released by CD4+ T cells infected with human retroviruses should prove useful in studies of the pathogenesis of KS.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Nakamura, S -- Salahuddin, S Z -- Biberfeld, P -- Ensoli, B -- Markham, P D -- Wong-Staal, F -- Gallo, R C -- New York, N.Y. -- Science. 1988 Oct 21;242(4877):426-30.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratory of Tumor Cell Biology, National Cancer Institute, Bethesda, MD 20892.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3262925" target="_blank"〉PubMed〈/a〉

    Angiogenic properties of Kaposi's sarcoma-derived cells after long-term culture in vitro (1988)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1988-10-21
    Description: Cells derived from lung biopsies and pleural effusions from AIDS patients with Kaposi's sarcoma (KS) of the lungs were established in long-term culture with the aid of conditioned medium from HTLV-II-transformed T cells (HTLV-II CM). These AIDS-KS cells were similar to the so-called spindle cells in KS lesions and had some of their features. They produced factors that supported their own growth (autocrine) and the growth of other cells (paracrine), including umbilical vein endothelium and fibroblasts. That the AIDS-KS cells also expressed potent angiogenic activity was demonstrated by the chorioallantoic membrane assay and by subcutaneous inoculation of AIDS-KS cells into nude mice, which resulted in the development of angiogenic lesions composed of mouse cells and showing histological features similar to those of human KS lesions. These data suggest that AIDS-associated KS and possibly other types of KS may be initiated by signals that induce the growth of particular cells (spindle cells of lymphatic or vascular origin) and the expression of autocrine and paracrine activities.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Salahuddin, S Z -- Nakamura, S -- Biberfeld, P -- Kaplan, M H -- Markham, P D -- Larsson, L -- Gallo, R C -- New York, N.Y. -- Science. 1988 Oct 21;242(4877):430-3.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratory of Tumor Cell Biology, National Cancer Institute, Bethesda, MD 20892.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2459779" target="_blank"〉PubMed〈/a〉

    Toll-like receptor triggering of a vitamin D-mediated human antimicrobial response (2006)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2006-02-25
    Description: In innate immune responses, activation of Toll-like receptors (TLRs) triggers direct antimicrobial activity against intracellular bacteria, which in murine, but not human, monocytes and macrophages is mediated principally by nitric oxide. We report here that TLR activation of human macrophages up-regulated expression of the vitamin D receptor and the vitamin D-1-hydroxylase genes, leading to induction of the antimicrobial peptide cathelicidin and killing of intracellular Mycobacterium tuberculosis. We also observed that sera from African-American individuals, known to have increased susceptibility to tuberculosis, had low 25-hydroxyvitamin D and were inefficient in supporting cathelicidin messenger RNA induction. These data support a link between TLRs and vitamin D-mediated innate immunity and suggest that differences in ability of human populations to produce vitamin D may contribute to susceptibility to microbial infection.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Liu, Philip T -- Stenger, Steffen -- Li, Huiying -- Wenzel, Linda -- Tan, Belinda H -- Krutzik, Stephan R -- Ochoa, Maria Teresa -- Schauber, Jurgen -- Wu, Kent -- Meinken, Christoph -- Kamen, Diane L -- Wagner, Manfred -- Bals, Robert -- Steinmeyer, Andreas -- Zugel, Ulrich -- Gallo, Richard L -- Eisenberg, David -- Hewison, Martin -- Hollis, Bruce W -- Adams, John S -- Bloom, Barry R -- Modlin, Robert L -- AI052453/AI/NIAID NIH HHS/ -- AI22553/AI/NIAID NIH HHS/ -- AI47868/AI/NIAID NIH HHS/ -- AI48176/AI/NIAID NIH HHS/ -- AR45676/AR/NIAMS NIH HHS/ -- AR50626/AR/NIAMS NIH HHS/ -- HD043921/HD/NICHD NIH HHS/ -- K22 AI085025/AI/NIAID NIH HHS/ -- RR00425/RR/NCRR NIH HHS/ -- New York, N.Y. -- Science. 2006 Mar 24;311(5768):1770-3.
