    Heterozygous germ line hCHK2 mutations in Li-Fraumeni syndrome (2000)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 2000-01-05
    Beschreibung: The hCHK2 gene encodes the human homolog of the yeast Cds1 and Rad53 G2 checkpoint kinases, whose activation in response to DNA damage prevents cellular entry into mitosis. Here, it is shown that heterozygous germ line mutations in hCHK2 occur in Li-Fraumeni syndrome, a highly penetrant familial cancer phenotype usually associated with inherited mutations in the TP53 gene. These observations suggest that hCHK2 is a tumor suppressor gene conferring predisposition to sarcoma, breast cancer, and brain tumors, and they also provide a link between the central role of p53 inactivation in human cancer and the well-defined G2 checkpoint in yeast.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bell, D W -- Varley, J M -- Szydlo, T E -- Kang, D H -- Wahrer, D C -- Shannon, K E -- Lubratovich, M -- Verselis, S J -- Isselbacher, K J -- Fraumeni, J F -- Birch, J M -- Li, F P -- Garber, J E -- Haber, D A -- New York, N.Y. -- Science. 1999 Dec 24;286(5449):2528-31.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Massachusetts General Hospital Center for Cancer Risk Analysis and Harvard Medical School, Building 149, Charlestown, MA 02129, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/10617473" target="_blank"〉PubMed〈/a〉

    A Systematic Search for Short-term Variability of EGRET Sources (2000)
    In:  CASI
    Details
    Publikationsdatum: 2013-08-29
    Beschreibung: The 3rd EGRET Catalog of High-energy Gamma-ray Sources contains 170 unidentified sources, and there is great interest in the nature of these sources. One means of determining source class is the study of flux variability on time scales of days; pulsars are believed to be stable on these time scales while blazers are known to be highly variable. In addition, previous work has demonstrated that 3EG J0241-6103 and 3EG J1837-0606 are candidates for a new gamma-ray source class. These sources near the Galactic plane display transient behavior but cannot be associated with any known blazers. Although, many instances of flaring AGN have been reported, the EGRET database has not been systematically searched for occurrences of short-timescale (approximately 1 day) variability. These considerations have led us to conduct a systematic search for short-term variability in EGRET data, covering all viewing periods through proposal cycle 4. Six 3EG catalog sources are reported here to display variability on short time scales; four of them are unidentified. In addition, three non-catalog variable sources are discussed.

    Neurodegeneration prevented by lentiviral vector delivery of GDNF in primate models of Parkinson's disease (2000)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 2000-10-29
    Beschreibung: Lentiviral delivery of glial cell line-derived neurotrophic factor (lenti-GDNF) was tested for its trophic effects upon degenerating nigrostriatal neurons in nonhuman primate models of Parkinson's disease (PD). We injected lenti-GDNF into the striatum and substantia nigra of nonlesioned aged rhesus monkeys or young adult rhesus monkeys treated 1 week prior with 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP). Extensive GDNF expression with anterograde and retrograde transport was seen in all animals. In aged monkeys, lenti-GDNF augmented dopaminergic function. In MPTP-treated monkeys, lenti-GDNF reversed functional deficits and completely prevented nigrostriatal degeneration. Additionally, lenti-GDNF injections to intact rhesus monkeys revealed long-term gene expression (8 months). In MPTP-treated monkeys, lenti-GDNF treatment reversed motor deficits in a hand-reach task. These data indicate that GDNF delivery using a lentiviral vector system can prevent nigrostriatal degeneration and induce regeneration in primate models of PD and might be a viable therapeutic strategy for PD patients.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kordower, J H -- Emborg, M E -- Bloch, J -- Ma, S Y -- Chu, Y -- Leventhal, L -- McBride, J -- Chen, E Y -- Palfi, S -- Roitberg, B Z -- Brown, W D -- Holden, J E -- Pyzalski, R -- Taylor, M D -- Carvey, P -- Ling, Z -- Trono, D -- Hantraye, P -- Deglon, N -- Aebischer, P -- NS40578/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 2000 Oct 27;290(5492):767-73.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Neurological Sciences, Rush Presbyterian-St. Luke's Medical Center, Chicago, IL 60612, USA. jkordowe@rush.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/11052933" target="_blank"〉PubMed〈/a〉

    Role of brain insulin receptor in control of body weight and reproduction (2000)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 2000-09-23
    Beschreibung: Insulin receptors (IRs) and insulin signaling proteins are widely distributed throughout the central nervous system (CNS). To study the physiological role of insulin signaling in the brain, we created mice with a neuron-specific disruption of the IR gene (NIRKO mice). Inactivation of the IR had no impact on brain development or neuronal survival. However, female NIRKO mice showed increased food intake, and both male and female mice developed diet-sensitive obesity with increases in body fat and plasma leptin levels, mild insulin resistance, elevated plasma insulin levels, and hypertriglyceridemia. NIRKO mice also exhibited impaired spermatogenesis and ovarian follicle maturation because of hypothalamic dysregulation of luteinizing hormone. Thus, IR signaling in the CNS plays an important role in regulation of energy disposal, fuel metabolism, and reproduction.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bruning, J C -- Gautam, D -- Burks, D J -- Gillette, J -- Schubert, M -- Orban, P C -- Klein, R -- Krone, W -- Muller-Wieland, D -- Kahn, C R -- DK31036/DK/NIDDK NIH HHS/ -- DK55326-01A2/DK/NIDDK NIH HHS/ -- New York, N.Y. -- Science. 2000 Sep 22;289(5487):2122-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Klinik II und Poliklinik fur Innere Medizin and Center of Molecular Medicine (ZMMK) der Universitat zu Koln, Joseph Stelzmann Strasse 9, 50931 Cologne, Germany. jens.bruening@uni-koeln.de〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/11000114" target="_blank"〉PubMed〈/a〉

    CCD-Based XRD/XRF for Determining Environmental Mineralogy on Mars (2000)
    In:  CASI
    Details
    Publikationsdatum: 2004-12-03
    Beschreibung: Health effects from Martian dusts will be a concern for any manned Mars missions. Nuisance dusts plagued the Apollo astronauts, but dusts of more hazardous mineralogy, in habitats occupied by Mars astronauts weakened by a long-duration mission, may be more than a nuisance. Chemical hazards in Martian regolith attributable to S, Cl, Br, Cd, and Pb are known or strongly suspected to be present, but terrestrial studies of the health effects of dusts indicate that accurate determination of mineralogy is a critical factor in evaluating inhalation hazards. Mineral inhalation hazards such as the Group-I carcinogenic zeolite erionite, which is demonstrated to cause mesothelioma, cannot be identified by chemical analysis alone. Studies of palagonite analogs raise the possibility that erionite may occur on Mars. In addition to health effects concerns, environmental mineralogy has significant importance in resource extraction, groundwater use, and sustained agriculture. The high sulfur and chlorine content of Martian regolith will affect all of these uses, but the nature of mineralogic reservoirs for S and Cl will determine their uptake and concentration in extracted groundwater and in agricultural applications of regolith. Wet chemistry experiments planned for the Mars Environmental Compatibility Assessment (MECA) will define some of the consequences of water/soil interaction, but an understanding of the mineralogic basis for water-rock reactions is needed to understand the mechanisms of reaction and to apply the results of a few experiments to larger scales and different conditions.

    Raman Lidar Measurements of Water Vapor and Cirrus Clouds During the Passage of Hurricane Bonnie (2000)
    In:  Other Sources
    Details
    Publikationsdatum: 2019-07-17
    Beschreibung: The NASA/GSFC Scanning Raman Lidar (SRL) was stationed on Andros Island in the Bahamas during August - September, 1998 as a part of the third Convection and Moisture Experiment (CAMEX-3) which focussed on hurricane development and tracking. During the period August 21 - 24, hurricane Bonnie passed near Andros Island and influenced the water vapor and cirrus cloud measurements acquired by the SRL. Two drying signatures related to the hurricane were recorded by the SRL and other sensors. Cirrus cloud optical depths (at 351 nm) were also measured during this period. Optical depth values ranged from approximately 0.01 to 1.4. The influence of multiple scattering on these optical depth measurements was studied with the conclusion that the measured values of optical depth are less than the actual value by up to 20%. The UV/lR cirrus cloud optical depth ratio was estimated based on a comparison of lidar and GOES measurements. Simple radiative transfer model calculations compared with GOES satellite brightness temperatures indicate that satellite radiances are significantly affected by the presence of cirrus clouds if IR optical depths are approximately 0.02 or greater. This has implications for satellite cirrus detection requirements.

    Effects of environment on compensatory mutations to ameliorate costs of antibiotic resistance (2000)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 2000-02-26
    Beschreibung: Most types of antibiotic resistance impose a biological cost on bacterial fitness. These costs can be compensated, usually without loss of resistance, by second-site mutations during the evolution of the resistant bacteria in an experimental host or in a laboratory medium. Different fitness-compensating mutations were selected depending on whether the bacteria evolved through serial passage in mice or in a laboratory medium. This difference in mutation spectra was caused by either a growth condition-specific formation or selection of the compensated mutants. These results suggest that bacterial evolution to reduce the costs of antibiotic resistance can take different trajectories within and outside a host.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bjorkman, J -- Nagaev, I -- Berg, O G -- Hughes, D -- Andersson, D I -- New York, N.Y. -- Science. 2000 Feb 25;287(5457):1479-82.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Bacteriology, Swedish Institute for Infectious Disease Control, S-171 82 Solna, Sweden.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/10688795" target="_blank"〉PubMed〈/a〉

    Insect population control using a dominant, repressible, lethal genetic system (2000)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 2000-03-31
    Beschreibung: A major modification to the sterile insect technique is described, in which transgenic insects homozygous for a dominant, repressible, female-specific lethal gene system are used. We demonstrate two methods that give the required genetic characteristics in an otherwise wild-type genetic background. The first system uses a sex-specific promoter or enhancer to drive the expression of a repressible transcription factor, which in turn controls the expression of a toxic gene product. The second system uses non-sex-specific expression of the repressible transcription factor to regulate a selectively lethal gene product. Both methods work efficiently in Drosophila melanogaster, and we expect these principles to be widely applicable to more economically important organisms.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Thomas, D D -- Donnelly, C A -- Wood, R J -- Alphey, L S -- New York, N.Y. -- Science. 2000 Mar 31;287(5462):2474-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Zoology, Wellcome Trust Centre for the Epidemiology of Infectious Disease, Department of Zoology, University of Oxford, South Parks Road, Oxford OX1 3PS, UK.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/10741964" target="_blank"〉PubMed〈/a〉

    Structure of the RNA polymerase domain of E. coli primase (2000)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 2000-03-31
    Beschreibung: All cellular organisms use specialized RNA polymerases called "primases" to synthesize RNA primers for the initiation of DNA replication. The high-resolution crystal structure of a primase, comprising the catalytic core of the Escherichia coli DnaG protein, was determined. The core structure contains an active-site architecture that is unrelated to other DNA or RNA polymerase palm folds, but is instead related to the "toprim" fold. On the basis of the structure, it is likely that DnaG binds nucleic acid in a groove clustered with invariant residues and that DnaG is positioned within the replisome to accept single-stranded DNA directly from the replicative helicase.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Keck, J L -- Roche, D D -- Lynch, A S -- Berger, J M -- New York, N.Y. -- Science. 2000 Mar 31;287(5462):2482-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Molecular and Cell Biology, University of California, Berkeley, 229 Stanley Hall, no. 3206, Berkeley, CA 94720, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/10741967" target="_blank"〉PubMed〈/a〉
