    Regulation of daily locomotor activity and sleep by hypothalamic EGF receptor signaling (2001)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2001-12-26
    Description: The circadian clock in the suprachiasmatic nucleus (SCN) is thought to drive daily rhythms of behavior by secreting factors that act locally within the hypothalamus. In a systematic screen, we identified transforming growth factor-alpha (TGF-alpha) as a likely SCN inhibitor of locomotion. TGF-alpha is expressed rhythmically in the SCN, and when infused into the third ventricle it reversibly inhibited locomotor activity and disrupted circadian sleep-wake cycles. These actions are mediated by epidermal growth factor (EGF) receptors on neurons in the hypothalamic subparaventricular zone. Mice with a hypomorphic EGF receptor mutation exhibited excessive daytime locomotor activity and failed to suppress activity when exposed to light. These results implicate EGF receptor signaling in the daily control of locomotor activity, and identify a neural circuit in the hypothalamus that likely mediates the regulation of behavior both by the SCN and the retina.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kramer, A -- Yang, F C -- Snodgrass, P -- Li, X -- Scammell, T E -- Davis, F C -- Weitz, C J -- HD-18686/HD/NICHD NIH HHS/ -- MH62589/MH/NIMH NIH HHS/ -- New York, N.Y. -- Science. 2001 Dec 21;294(5551):2511-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Neurobiology, Harvard Medical School, Boston, MA 02115, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/11752569" target="_blank"〉PubMed〈/a〉

    Tissue-specific regulation of retinal and pituitary precursor cell proliferation (2002)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2002-07-20
    Description: Mammalian organogenesis requires the expansion of pluripotent precursor cells before the subsequent determination of specific cell types, but the tissue-specific molecular mechanisms that regulate the initial expansion of primordial cells remain poorly defined. We have genetically established that Six6 homeodomain factor, acting as a strong tissue-specific repressor, regulates early progenitor cell proliferation during mammalian retinogenesis and pituitary development. Six6, in association with Dach corepressors, regulates proliferation by directly repressing cyclin-dependent kinase inhibitors, including the p27Kip1 promoter. These data reveal a molecular mechanism by which a tissue-specific transcriptional repressor-corepressor complex can provide an organ-specific strategy for physiological expansion of precursor populations.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Li, Xue -- Perissi, Valentina -- Liu, Forrest -- Rose, David W -- Rosenfeld, Michael G -- 484/B/Telethon/Italy -- 5F32DK09814/DK/NIDDK NIH HHS/ -- New York, N.Y. -- Science. 2002 Aug 16;297(5584):1180-3.

    Induction and suppression of RNA silencing by an animal virus (2002)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2002-05-23
    Description: RNA silencing is a sequence-specific RNA degradation mechanism that is operational in plants and animals. Here, we show that flock house virus (FHV) is both an initiator and a target of RNA silencing in Drosophila host cells and that FHV infection requires suppression of RNA silencing by an FHV-encoded protein, B2. These findings establish RNA silencing as an adaptive antiviral defense in animal cells. B2 also inhibits RNA silencing in transgenic plants, providing evidence for a conserved RNA silencing pathway in the plant and animal kingdoms.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Li, Hongwei -- Li, Wan Xiang -- Ding, Shou Wei -- New York, N.Y. -- Science. 2002 May 17;296(5571):1319-21.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Plant Pathology and Center for Plant Cell Biology, University of California, Riverside, CA 92521, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/12016316" target="_blank"〉PubMed〈/a〉

    S-nitrosylation of parkin regulates ubiquitination and compromises parkin's protective function (2004)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2004-04-24
    Description: Parkin is an E3 ubiquitin ligase involved in the ubiquitination of proteins that are important in the survival of dopamine neurons in Parkinson's disease (PD). We show that parkin is S-nitrosylated in vitro, as well as in vivo in a mouse model of PD and in brains of patients with PD and diffuse Lewy body disease. Moreover, S-nitrosylation inhibits parkin's ubiquitin E3 ligase activity and its protective function. The inhibition of parkin's ubiquitin E3 ligase activity by S-nitrosylation could contribute to the degenerative process in these disorders by impairing the ubiquitination of parkin substrates.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Chung, Kenny K K -- Thomas, Bobby -- Li, Xiaojie -- Pletnikova, Olga -- Troncoso, Juan C -- Marsh, Laura -- Dawson, Valina L -- Dawson, Ted M -- NS38377/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 2004 May 28;304(5675):1328-31.
