    Search for cross-species transmission of porcine endogenous retrovirus in patients treated with living pig tissue. The XEN 111 Study Group (1999)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1999-08-24
    Description: Pig organs may offer a solution to the shortage of human donor organs for transplantation, but concerns remain about possible cross-species transmission of porcine endogenous retrovirus (PERV). Samples were collected from 160 patients who had been treated with various living pig tissues up to 12 years earlier. Reverse transcription-polymerase chain reaction (RT-PCR) and protein immunoblot analyses were performed on serum from all 160 patients. No viremia was detected in any patient. Peripheral blood mononuclear cells from 159 of the patients were analyzed by PCR using PERV-specific primers. No PERV infection was detected in any of the patients from whom sufficient DNA was extracted to allow complete PCR analysis (97 percent of the patients). Persistent microchimerism (presence of donor cells in the recipient) was observed in 23 patients for up to 8.5 years.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Paradis, K -- Langford, G -- Long, Z -- Heneine, W -- Sandstrom, P -- Switzer, W M -- Chapman, L E -- Lockey, C -- Onions, D -- Otto, E -- New York, N.Y. -- Science. 1999 Aug 20;285(5431):1236-41.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Imutran Ltd.

    Rare structural variants disrupt multiple genes in neurodevelopmental pathways in schizophrenia (2008)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2008-03-29
    Description: Schizophrenia is a devastating neurodevelopmental disorder whose genetic influences remain elusive. We hypothesize that individually rare structural variants contribute to the illness. Microdeletions and microduplications 〉100 kilobases were identified by microarray comparative genomic hybridization of genomic DNA from 150 individuals with schizophrenia and 268 ancestry-matched controls. All variants were validated by high-resolution platforms. Novel deletions and duplications of genes were present in 5% of controls versus 15% of cases and 20% of young-onset cases, both highly significant differences. The association was independently replicated in patients with childhood-onset schizophrenia as compared with their parents. Mutations in cases disrupted genes disproportionately from signaling networks controlling neurodevelopment, including neuregulin and glutamate pathways. These results suggest that multiple, individually rare mutations altering genes in neurodevelopmental pathways contribute to schizophrenia.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Walsh, Tom -- McClellan, Jon M -- McCarthy, Shane E -- Addington, Anjene M -- Pierce, Sarah B -- Cooper, Greg M -- Nord, Alex S -- Kusenda, Mary -- Malhotra, Dheeraj -- Bhandari, Abhishek -- Stray, Sunday M -- Rippey, Caitlin F -- Roccanova, Patricia -- Makarov, Vlad -- Lakshmi, B -- Findling, Robert L -- Sikich, Linmarie -- Stromberg, Thomas -- Merriman, Barry -- Gogtay, Nitin -- Butler, Philip -- Eckstrand, Kristen -- Noory, Laila -- Gochman, Peter -- Long, Robert -- Chen, Zugen -- Davis, Sean -- Baker, Carl -- Eichler, Evan E -- Meltzer, Paul S -- Nelson, Stanley F -- Singleton, Andrew B -- Lee, Ming K -- Rapoport, Judith L -- King, Mary-Claire -- Sebat, Jonathan -- HD043569/HD/NICHD NIH HHS/ -- M01 RR000046/RR/NCRR NIH HHS/ -- MH061355/MH/NIMH NIH HHS/ -- MH061464/MH/NIMH NIH HHS/ -- MH061528/MH/NIMH NIH HHS/ -- NS052108/NS/NINDS NIH HHS/ -- R01 HD043569/HD/NICHD NIH HHS/ -- RR000046/RR/NCRR NIH HHS/ -- RR025014/RR/NCRR NIH HHS/ -- U01 MH061355/MH/NIMH NIH HHS/ -- U01 MH061464/MH/NIMH NIH HHS/ -- U01 MH061528/MH/NIMH NIH HHS/ -- U24 NS052108/NS/NINDS NIH HHS/ -- UL1 RR025014/RR/NCRR NIH HHS/ -- Howard Hughes Medical Institute/ -- Intramural NIH HHS/ -- New York, N.Y. -- Science. 2008 Apr 25;320(5875):539-43. doi: 10.1126/science.1155174.

    A selective inhibitor of eIF2alpha dephosphorylation protects cells from ER stress (2005)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2005-02-12
    Description: Most protein phosphatases have little intrinsic substrate specificity, making selective pharmacological inhibition of specific dephosphorylation reactions a challenging problem. In a screen for small molecules that protect cells from endoplasmic reticulum (ER) stress, we identified salubrinal, a selective inhibitor of cellular complexes that dephosphorylate eukaryotic translation initiation factor 2 subunit alpha (eIF2alpha). Salubrinal also blocks eIF2alpha dephosphorylation mediated by a herpes simplex virus protein and inhibits viral replication. These results suggest that selective chemical inhibitors of eIF2alpha dephosphorylation may be useful in diseases involving ER stress or viral infection. More broadly, salubrinal demonstrates the feasibility of selective pharmacological targeting of cellular dephosphorylation events.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Boyce, Michael -- Bryant, Kevin F -- Jousse, Celine -- Long, Kai -- Harding, Heather P -- Scheuner, Donalyn -- Kaufman, Randal J -- Ma, Dawei -- Coen, Donald M -- Ron, David -- Yuan, Junying -- AI19838/AI/NIAID NIH HHS/ -- AI26077/AI/NIAID NIH HHS/ -- DDK42394/DK/NIDDK NIH HHS/ -- DK47119/DK/NIDDK NIH HHS/ -- ES08681/ES/NIEHS NIH HHS/ -- GM64703/GM/NIGMS NIH HHS/ -- NS35138/NS/NINDS NIH HHS/ -- R37-AG012859/AG/NIA NIH HHS/ -- New York, N.Y. -- Science. 2005 Feb 11;307(5711):935-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Cell Biology, Harvard Medical School, Boston, MA 02115, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/15705855" target="_blank"〉PubMed〈/a〉

    Extensive gene traffic on the mammalian X chromosome (2004)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2004-01-24
    Description: Mammalian sex chromosomes have undergone profound changes since evolving from ancestral autosomes. By examining retroposed genes in the human and mouse genomes, we demonstrate that, during evolution, the mammalian X chromosome has generated and recruited a disproportionately high number of functional retroposed genes, whereas the autosomes experienced lower gene turnover. Most autosomal copies originating from X-linked genes exhibited testis-biased expression. Such export is incompatible with mutational bias and is likely driven by natural selection to attain male germline function. However, the excess recruitment is consistent with a combination of both natural selection and mutational bias.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Emerson, J J -- Kaessmann, Henrik -- Betran, Esther -- Long, Manyuan -- GM-065429-01A1/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2004 Jan 23;303(5657):537-40.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Ecology and Evolution, University of Chicago, Chicago, IL 60637, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/14739461" target="_blank"〉PubMed〈/a〉

    Transcriptional maps of 10 human chromosomes at 5-nucleotide resolution (2005)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2005-03-26
    Description: Sites of transcription of polyadenylated and nonpolyadenylated RNAs for 10 human chromosomes were mapped at 5-base pair resolution in eight cell lines. Unannotated, nonpolyadenylated transcripts comprise the major proportion of the transcriptional output of the human genome. Of all transcribed sequences, 19.4, 43.7, and 36.9% were observed to be polyadenylated, nonpolyadenylated, and bimorphic, respectively. Half of all transcribed sequences are found only in the nucleus and for the most part are unannotated. Overall, the transcribed portions of the human genome are predominantly composed of interlaced networks of both poly A+ and poly A- annotated transcripts and unannotated transcripts of unknown function. This organization has important implications for interpreting genotype-phenotype associations, regulation of gene expression, and the definition of a gene.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Cheng, Jill -- Kapranov, Philipp -- Drenkow, Jorg -- Dike, Sujit -- Brubaker, Shane -- Patel, Sandeep -- Long, Jeffrey -- Stern, David -- Tammana, Hari -- Helt, Gregg -- Sementchenko, Victor -- Piccolboni, Antonio -- Bekiranov, Stefan -- Bailey, Dione K -- Ganesh, Madhavan -- Ghosh, Srinka -- Bell, Ian -- Gerhard, Daniela S -- Gingeras, Thomas R -- New York, N.Y. -- Science. 2005 May 20;308(5725):1149-54.

    Naturally occurring variation in bristle number and DNA polymorphisms at the scabrous locus of Drosophila melanogaster (1994)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1994-12-09
    Description: The association between quantitative genetic variation in bristle number and molecular variation at a candidate neurogenic locus, scabrous, was examined in Drosophila melanogaster. Approximately 32 percent of the genetic variation in abdominal bristle number (21 percent for sternopleural bristle number) among 47 second chromosomes from a natural population was correlated with DNA sequence polymorphisms at this locus. Several polymorphic sites associated with large phenotypic effects occurred at intermediate frequency. Quantitative genetic variation in natural populations caused by alleles that have large effects at a few loci and that segregate at intermediate frequencies conflicts with the classical infinitesimal model of the genetic basis of quantitative variation.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lai, C -- Lyman, R F -- Long, A D -- Langley, C H -- Mackay, T F -- GM45146/GM/NIGMS NIH HHS/ -- GM45344/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1994 Dec 9;266(5191):1697-702.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Center for Population Biology, University of California at Davis 95616.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7992053" target="_blank"〉PubMed〈/a〉

    Natural selection shapes genome-wide patterns of copy-number polymorphism in Drosophila melanogaster (2008)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2008-06-07
    Description: The role that natural selection plays in governing the locations and early evolution of copy-number mutations remains largely unexplored. We used high-density full-genome tiling arrays to create a fine-scale genomic map of copy-number polymorphisms (CNPs) in Drosophila melanogaster. We inferred a total of 2658 independent CNPs, 56% of which overlap genes. These include CNPs that are likely to be under positive selection, most notably high-frequency duplications encompassing toxin-response genes. The locations and frequencies of CNPs are strongly shaped by purifying selection, with deletions under stronger purifying selection than duplications. Among duplications, those overlapping exons or introns, as well as those falling on the X chromosome, seem to be subject to stronger purifying selection.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Emerson, J J -- Cardoso-Moreira, Margarida -- Borevitz, Justin O -- Long, Manyuan -- New York, N.Y. -- Science. 2008 Jun 20;320(5883):1629-31. doi: 10.1126/science.1158078.

    Postnatal genome editing partially restores dystrophin expression in a mouse model of muscular dystrophy (2016)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2016-01-02
    Description: CRISPR/Cas9-mediated genome editing holds clinical potential for treating genetic diseases, such as Duchenne muscular dystrophy (DMD), which is caused by mutations in the dystrophin gene. To correct DMD by skipping mutant dystrophin exons in postnatal muscle tissue in vivo, we used adeno-associated virus-9 (AAV9) to deliver gene-editing components to postnatal mdx mice, a model of DMD. Different modes of AAV9 delivery were systematically tested, including intraperitoneal at postnatal day 1 (P1), intramuscular at P12, and retro-orbital at P18. Each of these methods restored dystrophin protein expression in cardiac and skeletal muscle to varying degrees, and expression increased from 3 to 12 weeks after injection. Postnatal gene editing also enhanced skeletal muscle function, as measured by grip strength tests 4 weeks after injection. This method provides a potential means of correcting mutations responsible for DMD and other monogenic disorders after birth.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4760628/" 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/PMC4760628/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Long, Chengzu -- Amoasii, Leonela -- Mireault, Alex A -- McAnally, John R -- Li, Hui -- Sanchez-Ortiz, Efrain -- Bhattacharyya, Samadrita -- Shelton, John M -- Bassel-Duby, Rhonda -- Olson, Eric N -- DK-099653/DK/NIDDK NIH HHS/ -- HL-077439/HL/NHLBI NIH HHS/ -- HL-093039/HL/NHLBI NIH HHS/ -- HL-111665/HL/NHLBI NIH HHS/ -- R01 DK099653/DK/NIDDK NIH HHS/ -- R01 HL077439/HL/NHLBI NIH HHS/ -- R01 HL093039/HL/NHLBI NIH HHS/ -- R01 HL111665/HL/NHLBI NIH HHS/ -- U01 HL100401/HL/NHLBI NIH HHS/ -- U01-HL-100401/HL/NHLBI NIH HHS/ -- U54 HD 087351/HD/NICHD NIH HHS/ -- New York, N.Y. -- Science. 2016 Jan 22;351(6271):400-3. doi: 10.1126/science.aad5725.

    Neural circuits. Inhibition protects acquired song segments during vocal learning in zebra finches (2016)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2016-01-28
    Description: Vocal imitation involves incorporating instructive auditory information into relevant motor circuits through processes that are poorly understood. In zebra finches, we found that exposure to a tutor's song drives spiking activity within premotor neurons in the juvenile, whereas inhibition suppresses such responses upon learning in adulthood. We measured inhibitory currents evoked by the tutor song throughout development while simultaneously quantifying each bird's learning trajectory. Surprisingly, we found that the maturation of synaptic inhibition onto premotor neurons is correlated with learning but not age. We used synthetic tutoring to demonstrate that inhibition is selective for specific song elements that have already been learned and not those still in refinement. Our results suggest that structured inhibition plays a crucial role during song acquisition, enabling a piece-by-piece mastery of complex tasks.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Vallentin, Daniela -- Kosche, Georg -- Lipkind, Dina -- Long, Michael A -- R01NS075044/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 2016 Jan 15;351(6270):267-71. doi: 10.1126/science.aad3023.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉NYU Neuroscience Institute and Department of Otolaryngology, New York University Langone Medical Center, New York, NY 10016, USA.
