    A mutant Drosophila insulin receptor homolog that extends life-span and impairs neuroendocrine function (2001)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 2001-04-09
    Beschreibung: The Drosophila melanogaster gene insulin-like receptor (InR) is homologous to mammalian insulin receptors as well as to Caenorhabditis elegans daf-2, a signal transducer regulating worm dauer formation and adult longevity. We describe a heteroallelic, hypomorphic genotype of mutant InR, which yields dwarf females with up to an 85% extension of adult longevity and dwarf males with reduced late age-specific mortality. Treatment of the long-lived InR dwarfs with a juvenile hormone analog restores life expectancy toward that of wild-type controls. We conclude that juvenile hormone deficiency, which results from InR signal pathway mutation, is sufficient to extend life-span, and that in flies, insulin-like ligands nonautonomously mediate aging through retardation of growth or activation of specific endocrine tissue.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Tatar, M -- Kopelman, A -- Epstein, D -- Tu, M P -- Yin, C M -- Garofalo, R S -- R01 AG16632/AG/NIA NIH HHS/ -- New York, N.Y. -- Science. 2001 Apr 6;292(5514):107-10.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Brown University, Providence, RI 02912, USA., University of Massachusetts, Amherst, MA 01003, USA.

    Molecular analysis of protein assembly in muscle development (1991)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 1991-03-01
    Beschreibung: The challenge presented by myofibril assembly in striated muscle is to understand the molecular mechanisms by which its protein components are arranged at each level of organization. Recent advances in the genetics and cell biology of muscle development have shown that in vivo assembly of the myofilaments requires a complex array of structural and associated proteins and that organization of whole sarcomeres occurs initially at the cell membrane. These studies have been complemented by in vitro analyses of the renaturation, polymerization, and three-dimensional structure of the purified proteins.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Epstein, H F -- Fischman, D A -- AR-32147/AR/NIAMS NIH HHS/ -- GM-33223/GM/NIGMS NIH HHS/ -- HL-42267/HL/NHLBI NIH HHS/ -- etc. -- New York, N.Y. -- Science. 1991 Mar 1;251(4997):1039-44.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Neurology, Baylor College of Medicine, Houston, TX 77030.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1998120" target="_blank"〉PubMed〈/a〉

    Interconversion between intestinal stem cell populations in distinct niches (2011)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 2011-11-15
    Beschreibung: Intestinal epithelial stem cell identity and location have been the subject of substantial research. Cells in the +4 niche are slow-cycling and label-retaining, whereas a different stem cell niche located at the crypt base is occupied by crypt base columnar (CBC) cells. CBCs are distinct from +4 cells, and the relationship between them is unknown, though both give rise to all intestinal epithelial lineages. We demonstrate that Hopx, an atypical homeobox protein, is a specific marker of +4 cells. Hopx-expressing cells give rise to CBCs and all mature intestinal epithelial lineages. Conversely, CBCs can give rise to +4 Hopx-positive cells. These findings demonstrate a bidirectional lineage relationship between active and quiescent stem cells in their niches.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3705713/" 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/PMC3705713/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Takeda, Norifumi -- Jain, Rajan -- LeBoeuf, Matthew R -- Wang, Qiaohong -- Lu, Min Min -- Epstein, Jonathan A -- R01 HL071546/HL/NHLBI NIH HHS/ -- U01 HL100405/HL/NHLBI NIH HHS/ -- New York, N.Y. -- Science. 2011 Dec 9;334(6061):1420-4. doi: 10.1126/science.1213214.

    A memory retrieval-extinction procedure to prevent drug craving and relapse (2012)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 2012-04-14
    Beschreibung: Drug use and relapse involve learned associations between drug-associated environmental cues and drug effects. Extinction procedures in the clinic can suppress conditioned responses to drug cues, but the extinguished responses typically reemerge after exposure to the drug itself (reinstatement), the drug-associated environment (renewal), or the passage of time (spontaneous recovery). We describe a memory retrieval-extinction procedure that decreases conditioned drug effects and drug seeking in rat models of relapse, and drug craving in abstinent heroin addicts. In rats, daily retrieval of drug-associated memories 10 minutes or 1 hour but not 6 hours before extinction sessions attenuated drug-induced reinstatement, spontaneous recovery, and renewal of conditioned drug effects and drug seeking. In heroin addicts, retrieval of drug-associated memories 10 minutes before extinction sessions attenuated cue-induced heroin craving 1, 30, and 180 days later. The memory retrieval-extinction procedure is a promising nonpharmacological method for decreasing drug craving and relapse during abstinence.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3695463/" 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/PMC3695463/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Xue, Yan-Xue -- Luo, Yi-Xiao -- Wu, Ping -- Shi, Hai-Shui -- Xue, Li-Fen -- Chen, Chen -- Zhu, Wei-Li -- Ding, Zeng-Bo -- Bao, Yan-ping -- Shi, Jie -- Epstein, David H -- Shaham, Yavin -- Lu, Lin -- Z99 DA999999/Intramural NIH HHS/ -- ZIA DA000434-12/Intramural NIH HHS/ -- New York, N.Y. -- Science. 2012 Apr 13;336(6078):241-5. doi: 10.1126/science.1215070.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉National Institute on Drug Dependence, Peking University, Beijing, China.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/22499948" target="_blank"〉PubMed〈/a〉

    Protection against malaria by intravenous immunization with a nonreplicating sporozoite vaccine (2013)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 2013-08-10
    Beschreibung: Consistent, high-level, vaccine-induced protection against human malaria has only been achieved by inoculation of Plasmodium falciparum (Pf) sporozoites (SPZ) by mosquito bites. We report that the PfSPZ Vaccine--composed of attenuated, aseptic, purified, cryopreserved PfSPZ--was safe and well tolerated when administered four to six times intravenously (IV) to 40 adults. Zero of six subjects receiving five doses and three of nine subjects receiving four doses of 1.35 x 10(5) PfSPZ Vaccine and five of six nonvaccinated controls developed malaria after controlled human malaria infection (P = 0.015 in the five-dose group and P = 0.028 for overall, both versus controls). PfSPZ-specific antibody and T cell responses were dose-dependent. These data indicate that there is a dose-dependent immunological threshold for establishing high-level protection against malaria that can be achieved with IV administration of a vaccine that is safe and meets regulatory standards.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Seder, Robert A -- Chang, Lee-Jah -- Enama, Mary E -- Zephir, Kathryn L -- Sarwar, Uzma N -- Gordon, Ingelise J -- Holman, LaSonji A -- James, Eric R -- Billingsley, Peter F -- Gunasekera, Anusha -- Richman, Adam -- Chakravarty, Sumana -- Manoj, Anita -- Velmurugan, Soundarapandian -- Li, MingLin -- Ruben, Adam J -- Li, Tao -- Eappen, Abraham G -- Stafford, Richard E -- Plummer, Sarah H -- Hendel, Cynthia S -- Novik, Laura -- Costner, Pamela J M -- Mendoza, Floreliz H -- Saunders, Jamie G -- Nason, Martha C -- Richardson, Jason H -- Murphy, Jittawadee -- Davidson, Silas A -- Richie, Thomas L -- Sedegah, Martha -- Sutamihardja, Awalludin -- Fahle, Gary A -- Lyke, Kirsten E -- Laurens, Matthew B -- Roederer, Mario -- Tewari, Kavita -- Epstein, Judith E -- Sim, B Kim Lee -- Ledgerwood, Julie E -- Graham, Barney S -- Hoffman, Stephen L -- VRC 312 Study Team -- 3R44AI055229-06S1/AI/NIAID NIH HHS/ -- 4R44AI055229-08/AI/NIAID NIH HHS/ -- 5R44AI058499-05/AI/NIAID NIH HHS/ -- N01-AI-40096/AI/NIAID NIH HHS/ -- Intramural NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2013 Sep 20;341(6152):1359-65. doi: 10.1126/science.1241800.

    Role of the myosin assembly protein UNC-45 as a molecular chaperone for myosin (2002)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 2002-01-26
    Beschreibung: The organization of myosin into motile cellular structures requires precise temporal and spatial regulation. Proteins containing a UCS (UNC-45/CRO1/She4p) domain are necessary for the incorporation of myosin into the contractile ring during cytokinesis and into thick filaments during muscle development. We report that the carboxyl-terminal regions of UNC-45 bound and exerted chaperone activity on the myosin head. The amino-terminal tetratricopeptide repeat domain of UNC-45 bound the molecular chaperone Hsp90. Thus, UNC-45 functions both as a molecular chaperone and as an Hsp90 co-chaperone for myosin, which can explain previous findings of altered assembly and decreased accumulation of myosin in UNC-45 mutants of Caenorhabditis elegans.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Barral, Jose M -- Hutagalung, Alex H -- Brinker, Achim -- Hartl, F Ulrich -- Epstein, Henry F -- New York, N.Y. -- Science. 2002 Jan 25;295(5555):669-71.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biochemistry and Molecular Biology, Baylor College of Medicine, Houston, TX 77030, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/11809970" target="_blank"〉PubMed〈/a〉

    Rab5 is necessary for the biogenesis of the endolysosomal system in vivo (2012)
    Nature Publishing Group (NPG)
    Details
    Publikationsdatum: 2012-05-25
    Beschreibung: An outstanding question is how cells control the number and size of membrane organelles. The small GTPase Rab5 has been proposed to be a master regulator of endosome biogenesis. Here, to test this hypothesis, we developed a mathematical model of endosome dependency on Rab5 and validated it by titrating down all three Rab5 isoforms in adult mouse liver using state-of-the-art RNA interference technology. Unexpectedly, the endocytic system was resilient to depletion of Rab5 and collapsed only when Rab5 decreased to a critical level. Loss of Rab5 below this threshold caused a marked reduction in the number of early endosomes, late endosomes and lysosomes, associated with a block of low-density lipoprotein endocytosis. Loss of endosomes caused failure to deliver apical proteins to the bile canaliculi, suggesting a requirement for polarized cargo sorting. Our results demonstrate for the first time, to our knowledge, the role of Rab5 as an endosome organizer in vivo and reveal the resilience mechanisms of the endocytic system.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Zeigerer, Anja -- Gilleron, Jerome -- Bogorad, Roman L -- Marsico, Giovanni -- Nonaka, Hidenori -- Seifert, Sarah -- Epstein-Barash, Hila -- Kuchimanchi, Satya -- Peng, Chang Geng -- Ruda, Vera M -- Del Conte-Zerial, Perla -- Hengstler, Jan G -- Kalaidzidis, Yannis -- Koteliansky, Victor -- Zerial, Marino -- England -- Nature. 2012 May 23;485(7399):465-70. doi: 10.1038/nature11133.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Max Planck Institute of Molecular Cell Biology and Genetics, 01307 Dresden, Germany.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/22622570" target="_blank"〉PubMed〈/a〉

    Isolation and characterization of a bat SARS-like coronavirus that uses the ACE2 receptor (2013)
    Nature Publishing Group (NPG)
    Details
    Publikationsdatum: 2013-11-01
    Beschreibung: The 2002-3 pandemic caused by severe acute respiratory syndrome coronavirus (SARS-CoV) was one of the most significant public health events in recent history. An ongoing outbreak of Middle East respiratory syndrome coronavirus suggests that this group of viruses remains a key threat and that their distribution is wider than previously recognized. Although bats have been suggested to be the natural reservoirs of both viruses, attempts to isolate the progenitor virus of SARS-CoV from bats have been unsuccessful. Diverse SARS-like coronaviruses (SL-CoVs) have now been reported from bats in China, Europe and Africa, but none is considered a direct progenitor of SARS-CoV because of their phylogenetic disparity from this virus and the inability of their spike proteins to use the SARS-CoV cellular receptor molecule, the human angiotensin converting enzyme II (ACE2). Here we report whole-genome sequences of two novel bat coronaviruses from Chinese horseshoe bats (family: Rhinolophidae) in Yunnan, China: RsSHC014 and Rs3367. These viruses are far more closely related to SARS-CoV than any previously identified bat coronaviruses, particularly in the receptor binding domain of the spike protein. Most importantly, we report the first recorded isolation of a live SL-CoV (bat SL-CoV-WIV1) from bat faecal samples in Vero E6 cells, which has typical coronavirus morphology, 99.9% sequence identity to Rs3367 and uses ACE2 from humans, civets and Chinese horseshoe bats for cell entry. Preliminary in vitro testing indicates that WIV1 also has a broad species tropism. Our results provide the strongest evidence to date that Chinese horseshoe bats are natural reservoirs of SARS-CoV, and that intermediate hosts may not be necessary for direct human infection by some bat SL-CoVs. They also highlight the importance of pathogen-discovery programs targeting high-risk wildlife groups in emerging disease hotspots as a strategy for pandemic preparedness.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ge, Xing-Yi -- Li, Jia-Lu -- Yang, Xing-Lou -- Chmura, Aleksei A -- Zhu, Guangjian -- Epstein, Jonathan H -- Mazet, Jonna K -- Hu, Ben -- Zhang, Wei -- Peng, Cheng -- Zhang, Yu-Ji -- Luo, Chu-Ming -- Tan, Bing -- Wang, Ning -- Zhu, Yan -- Crameri, Gary -- Zhang, Shu-Yi -- Wang, Lin-Fa -- Daszak, Peter -- Shi, Zheng-Li -- R01AI079231/AI/NIAID NIH HHS/ -- R01TW005869/TW/FIC NIH HHS/ -- R56TW009502/TW/FIC NIH HHS/ -- England -- Nature. 2013 Nov 28;503(7477):535-8. doi: 10.1038/nature12711.
