    Association of BRCA1 with the hRad50-hMre11-p95 complex and the DNA damage response (1999)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1999-07-31
    Description: BRCA1 encodes a tumor suppressor that is mutated in familial breast and ovarian cancers. Here, it is shown that BRCA1 interacts in vitro and in vivo with hRad50, which forms a complex with hMre11 and p95/nibrin. Upon irradiation, BRCA1 was detected in discrete foci in the nucleus, which colocalize with hRad50. Formation of irradiation-induced foci positive for BRCA1, hRad50, hMre11, or p95 was dramatically reduced in HCC/1937 breast cancer cells carrying a homozygous mutation in BRCA1 but was restored by transfection of wild-type BRCA1. Ectopic expression of wild-type, but not mutated, BRCA1 in these cells rendered them less sensitive to the DNA damage agent, methyl methanesulfonate. These data suggest that BRCA1 is important for the cellular responses to DNA damage that are mediated by the hRad50-hMre11-p95 complex.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Zhong, Q -- Chen, C F -- Li, S -- Chen, Y -- Wang, C C -- Xiao, J -- Chen, P L -- Sharp, Z D -- Lee, W H -- CA 30195/CA/NCI NIH HHS/ -- CA 58183/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 1999 Jul 30;285(5428):747-50.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Molecular Medicine, Institute of Biotechnology, University of Texas Health Science Center at San Antonio, 15355 Lambda Drive, San Antonio, TX 78245, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/10426999" target="_blank"〉PubMed〈/a〉

    DNA topoisomerase IIbeta and neural development (1999)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1999-12-30
    Description: DNA topoisomerase IIbeta is shown to have an unsuspected and critical role in neural development. Neurogenesis was normal in IIbeta mutant mice, but motor axons failed to contact skeletal muscles, and sensory axons failed to enter the spinal cord. Despite an absence of innervation, clusters of acetylcholine receptors were concentrated in the central region of skeletal muscles, thereby revealing patterning mechanisms that are autonomous to skeletal muscle. The defects in motor axon growth in IIbeta mutant mice resulted in a breathing impairment and death of the pups shortly after birth.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Yang, X -- Li, W -- Prescott, E D -- Burden, S J -- Wang, J C -- NS10537/NS/NINDS NIH HHS/ -- NS27963/NS/NINDS NIH HHS/ -- NS36193/NS/NINDS NIH HHS/ -- R01 NS036193/NS/NINDS NIH HHS/ -- R01 NS036193-02/NS/NINDS NIH HHS/ -- R01 NS041311/NS/NINDS NIH HHS/ -- R01 NS041311-03/NS/NINDS NIH HHS/ -- etc. -- New York, N.Y. -- Science. 2000 Jan 7;287(5450):131-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Skirball Institute of Molecular Medicine, New York University Medical School, 540 First Avenue, New York, NY 10016, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/10615047" target="_blank"〉PubMed〈/a〉

    Induction of apoptosis in uninfected lymphocytes by HIV-1 Tat protein (1995)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1995-04-21
    Description: Infection by human immunodeficiency virus-type 1 (HIV-1) is typified by the progressive depletion of CD4 T lymphocytes and deterioration of immune function in most patients. A central unresolved issue in acquired immunodeficiency syndrome (AIDS) pathogenesis is the mechanism underlying this T cell depletion. HIV-1 Tat protein was shown to induce cell death by apoptosis in a T cell line and in cultured peripheral blood mononuclear cells from uninfected donors. This Tat-induced apoptosis was inhibitable by growth factors and was associated with enhanced activation of cyclin-dependent kinases.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Li, C J -- Friedman, D J -- Wang, C -- Metelev, V -- Pardee, A B -- AI-35511/AI/NIAID NIH HHS/ -- New York, N.Y. -- Science. 1995 Apr 21;268(5209):429-31.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Division of Cell Growth and Regulation, Dana-Farber Cancer Institute, Boston, MA, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7716549" target="_blank"〉PubMed〈/a〉

    Atomic-scale desorption through electronic and vibrational excitation mechanisms (1995)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1995-06-16
    Description: The scanning tunneling microscope has been used to desorb hydrogen from hydrogen-terminated silicon (100) surfaces. As a result of control of the dose of incident electrons, a countable number of desorption sites can be created and the yield and cross section are thereby obtained. Two distinct desorption mechanisms are observed: (i) direct electronic excitation of the Si-H bond by field-emitted electrons and (ii) an atomic resolution mechanism that involves multiple-vibrational excitation by tunneling electrons at low applied voltages. This vibrational heating effect offers significant potential for controlling surface reactions involving adsorbed individual atoms and molecules.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Shen, T C -- Wang, C -- Abeln, G C -- Tucker, J R -- Lyding, J W -- Avouris, P -- Walkup, R E -- New York, N.Y. -- Science. 1995 Jun 16;268(5217):1590-2.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17754609" target="_blank"〉PubMed〈/a〉

    Theory of quasielastic light scattering of a ternary solution consisting of two homopolymers with arbitrary optical, hydrodynamic, and thermodynamic properties (1997)

    Notes: The temporal dependence of the time correlation function detected by quasielastic light (QEL) scattering in solution consisting of two homopolymers with arbitrary hydrodynamic and thermodynamic properties is investigated. New results appropriate for the ternary polymer solution in various concentrations are obtained. These new results should facilitate the analysis of the QEL scattering data of a ternary solution in any concentrations. Information about tracer diffusion coefficients of the constitutive polymers and their excluded volume interaction parameter is shown to be obtainable from the QEL experiment of the ternary polymer solution. Applications to ternary polymer solutions with one polymer isorefractive with the solvent, solutions with two polymers differing only in molecular weight, and solutions with two polymers having arbitrary refractive index increments are discussed. Clarification in regard to the ternary solution under the zero average contrast (ZAC) condition is also made. It is shown that under the ZAC condition, the autocorrelation function of the composition fluctuation in general decays with two exponentials, even at 1:1 symmetric composition. © 1997 American Institute of Physics.

    Quasielastic light scattering study of ternary polymer solutions of polystyrene and poly(methyl methacrylate) in dioxane (1997)

    Notes: The dynamic behavior of the mixture polystyrene (PS)–poly(methyl methacrylate) (PMMA)–dioxane in the semidilute concentration regime has been investigated by quasielastic light scattering. Two types of PS–PMMA–dioxane solution have been studied: One at a fixed composition but with different total polymer concentrations, and the other at a fixed total polymer concentration but with different compositions. For each solution, two distinct modes have been observed in the autocorrelation function of the scattered light; their relaxation times and relative amplitudes are studied as functions of composition and total polymer concentration. The present method differ from the previous one by not requiring one polymer to be isorefractive with solvent. By using the experimental results and with the help of theory, the self-diffusion coefficients of PS and PMMA and the Flory–Huggins interaction parameter χF have been deduced. The χF values obtained in this work are in good agreement with that obtained by other methods. © 1997 American Institute of Physics.

    Effects of external electric field on semidilute polymer solutions probed by dynamic light scattering (1997)

    Notes: Dynamic light scattering studies of polystyrene (PS) in tetrahydrofuran (THF) in 1,4-dioxane (DO) and in THF/DO mixed solvent, subject to an external dc field, have been carried out. In THF the rate constant for the decay of the intensity autocorrelation function (IACF) is found to increase with increasing the external applied electric field; in DO, the electric field is found to have only a negligible effect on the IACF; in the mixed solvent it exhibits an intermediate effect, depending on the THF content. A hydrodynamic theory is proposed to account for the observed electric field induced effect in THF. © 1997 American Institute of Physics.
