    Role of substrates and products of PI 3-kinase in regulating activation of Rac-related guanosine triphosphatases by Vav (1998)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1998-02-07
    Description: Mitogen stimulation of cytoskeletal changes and c-jun amino-terminal kinases is mediated by Rac small guanine nucleotide-binding proteins. Vav, a guanosine diphosphate (GDP)-guanosine triphosphate (GTP) exchange factor for Rac that stimulates the exchange of bound GDP for GTP, bound to and was directly controlled by substrates and products of phosphoinositide (PI) 3-kinase. The PI 3-kinase substrate phosphatidylinositol-4,5-bisphosphate inhibited activation of Vav by the tyrosine kinase Lck, whereas the product phosphatidylinositol-3,4,5-trisphosphate enhanced phosphorylation and activation of Vav by Lck. Control of Vav in response to mitogens by the products of PI 3-kinase suggests a mechanism for Ras-dependent activation of Rac.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Han, J -- Luby-Phelps, K -- Das, B -- Shu, X -- Xia, Y -- Mosteller, R D -- Krishna, U M -- Falck, J R -- White, M A -- Broek, D -- CA50261/CA/NCI NIH HHS/ -- CA71443/CA/NCI NIH HHS/ -- GM31278/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1998 Jan 23;279(5350):558-60.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biochemistry and Molecular Biology, Norris Comprehensive Cancer Center, University of Southern California, Los Angeles, CA 90033-0800, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9438848" target="_blank"〉PubMed〈/a〉

    Specific and nonhepatotoxic degradation of nuclear hepatitis B virus cccDNA (2014)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2014-02-22
    Description: Current antiviral agents can control but not eliminate hepatitis B virus (HBV), because HBV establishes a stable nuclear covalently closed circular DNA (cccDNA). Interferon-alpha treatment can clear HBV but is limited by systemic side effects. We describe how interferon-alpha can induce specific degradation of the nuclear viral DNA without hepatotoxicity and propose lymphotoxin-beta receptor activation as a therapeutic alternative. Interferon-alpha and lymphotoxin-beta receptor activation up-regulated APOBEC3A and APOBEC3B cytidine deaminases, respectively, in HBV-infected cells, primary hepatocytes, and human liver needle biopsies. HBV core protein mediated the interaction with nuclear cccDNA, resulting in cytidine deamination, apurinic/apyrimidinic site formation, and finally cccDNA degradation that prevented HBV reactivation. Genomic DNA was not affected. Thus, inducing nuclear deaminases-for example, by lymphotoxin-beta receptor activation-allows the development of new therapeutics that, in combination with existing antivirals, may cure hepatitis B.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lucifora, Julie -- Xia, Yuchen -- Reisinger, Florian -- Zhang, Ke -- Stadler, Daniela -- Cheng, Xiaoming -- Sprinzl, Martin F -- Koppensteiner, Herwig -- Makowska, Zuzanna -- Volz, Tassilo -- Remouchamps, Caroline -- Chou, Wen-Min -- Thasler, Wolfgang E -- Huser, Norbert -- Durantel, David -- Liang, T Jake -- Munk, Carsten -- Heim, Markus H -- Browning, Jeffrey L -- Dejardin, Emmanuel -- Dandri, Maura -- Schindler, Michael -- Heikenwalder, Mathias -- Protzer, Ulrike -- New York, N.Y. -- Science. 2014 Mar 14;343(6176):1221-8. doi: 10.1126/science.1243462.
