    S-nitrosylation of matrix metalloproteinases: signaling pathway to neuronal cell death (2002)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2002-08-17
    Description: Matrix metalloproteinases (MMPs) are implicated in the pathogenesis of neurodegenerative diseases and stroke. However, the mechanism of MMP activation remains unclear. We report that MMP activation involves S-nitrosylation. During cerebral ischemia in vivo, MMP-9 colocalized with neuronal nitric oxide synthase. S-Nitrosylation activated MMP-9 in vitro and induced neuronal apoptosis. Mass spectrometry identified the active derivative of MMP-9, both in vitro and in vivo, as a stable sulfinic or sulfonic acid, whose formation was triggered by S-nitrosylation. These findings suggest a potential extracellular proteolysis pathway to neuronal cell death in which S-nitrosylation activates MMPs, and further oxidation results in a stable posttranslational modification with pathological activity.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gu, Zezong -- Kaul, Marcus -- Yan, Boxu -- Kridel, Steven J -- Cui, Jiankun -- Strongin, Alex -- Smith, Jeffrey W -- Liddington, Robert C -- Lipton, Stuart A -- AR08505/AR/NIAMS NIH HHS/ -- P01 HD29587/HD/NICHD NIH HHS/ -- R01 AR42750/AR/NIAMS NIH HHS/ -- R01 CA 69306/CA/NCI NIH HHS/ -- R01 EY05477/EY/NEI NIH HHS/ -- R01 EY09024/EY/NEI NIH HHS/ -- R01 NS41207/NS/NINDS NIH HHS/ -- T32 AG00252/AG/NIA NIH HHS/ -- New York, N.Y. -- Science. 2002 Aug 16;297(5584):1186-90.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Center for Neuroscience and Aging, Program in Cell Adhesion and Extracellular Matrix Biology, The Burnham Institute, 10901 North Torrey Pines Road, La Jolla, CA 92037, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/12183632" target="_blank"〉PubMed〈/a〉

    HIV-1 coat protein neurotoxicity prevented by calcium channel antagonists (1990)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1990-04-20
    Description: Coat protein gp120 from the human immunodeficiency virus type-1 (HIV-1) increased intracellular free calcium and injured rodent retinal ganglion cells and hippocampal neurons in culture. Highly purified recombinant gp120 envelope protein produced these effects in a dose-dependent fashion at picomolar concentrations. Immunoprecipitation with antibody to gp120, but not with control immunoglobulin-containing serum, depleted solutions of the viral envelope protein and also prevented both the rise in intracellular calcium and neuronal toxicity. The gp120-induced increase in intracellular calcium was abrogated by transiently lowering extracellular calcium or by adding the dihydropyridine calcium channel antagonist nimodipine (100 nM). Calcium channel antagonists also prevented gp120-induced neuronal injury. In addition, intracellular stores appeared to contribute substantially to the increase in calcium elicited by gp120. Since increases in intracellular calcium have been associated with neurotoxicity, it is possible that an injurious effect of gp120 on neurons might be related to this mechanism and that treatment with calcium channel antagonists may prove useful in mitigating HIV-1-related neuronal injury.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Dreyer, E B -- Kaiser, P K -- Offermann, J T -- Lipton, S A -- EY 05477/EY/NEI NIH HHS/ -- NS 01395/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 1990 Apr 20;248(4953):364-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Neurology, Children's Hospital, Boston, MA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2326646" target="_blank"〉PubMed〈/a〉

    S-nitrosylation of Drp1 mediates beta-amyloid-related mitochondrial fission and neuronal injury (2009)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2009-04-04
    Description: Mitochondria continuously undergo two opposing processes, fission and fusion. The disruption of this dynamic equilibrium may herald cell injury or death and may contribute to developmental and neurodegenerative disorders. Nitric oxide functions as a signaling molecule, but in excess it mediates neuronal injury, in part via mitochondrial fission or fragmentation. However, the underlying mechanism for nitric oxide-induced pathological fission remains unclear. We found that nitric oxide produced in response to beta-amyloid protein, thought to be a key mediator of Alzheimer's disease, triggered mitochondrial fission, synaptic loss, and neuronal damage, in part via S-nitrosylation of dynamin-related protein 1 (forming SNO-Drp1). Preventing nitrosylation of Drp1 by cysteine mutation abrogated these neurotoxic events. SNO-Drp1 is increased in brains of human Alzheimer's disease patients and may thus contribute to the pathogenesis of neurodegeneration.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2823371/" 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/PMC2823371/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Cho, Dong-Hyung -- Nakamura, Tomohiro -- Fang, Jianguo -- Cieplak, Piotr -- Godzik, Adam -- Gu, Zezong -- Lipton, Stuart A -- P01 ES016738/ES/NIEHS NIH HHS/ -- P01 ES016738-01/ES/NIEHS NIH HHS/ -- P01 ES016738-010003/ES/NIEHS NIH HHS/ -- P01 ES016738-02/ES/NIEHS NIH HHS/ -- P01 ES016738-020003/ES/NIEHS NIH HHS/ -- P01 HD029587/HD/NICHD NIH HHS/ -- P01 HD029587-16/HD/NICHD NIH HHS/ -- P01 HD29587/HD/NICHD NIH HHS/ -- P30 NS057096/NS/NINDS NIH HHS/ -- P30 NS057096-04/NS/NINDS NIH HHS/ -- R01 EY005477/EY/NEI NIH HHS/ -- R01 EY005477-25/EY/NEI NIH HHS/ -- R01 EY05477/EY/NEI NIH HHS/ -- New York, N.Y. -- Science. 2009 Apr 3;324(5923):102-5. doi: 10.1126/science.1171091.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Center for Neuroscience, Aging, and Stem Cell Research, Burnham Institute for Medical Research, 10901 North Torrey Pines Road, La Jolla, CA 92037, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19342591" target="_blank"〉PubMed〈/a〉

    Description: Ganglion cells were dissociated from postnatal rat retinas, identified by specific fluorescent labels, and maintained in culture on a variety of substrates. Regeneration of processes by retinal ganglion cells was enhanced when the cells were plated on glass coated with a monoclonal antibody against the Thy-1 determinant. Plain glass and glass coated with polylysine, collagen, fibronectin, or other monoclonal antibodies supported the growth of neural processes, but were less effective than antibody to Thy-1.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Leifer, D -- Lipton, S A -- Barnstable, C J -- Masland, R H -- EY01075/EY/NEI NIH HHS/ -- EY03735/EY/NEI NIH HHS/ -- EY04179/EY/NEI NIH HHS/ -- New York, N.Y. -- Science. 1984 Apr 20;224(4646):303-6.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/6143400" target="_blank"〉PubMed〈/a〉

    Nicotinic antagonists enhance process outgrowth by rat retinal ganglion cells in culture (1988)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1988-03-11
    Description: Functional nicotinic cholinergic receptors are found on mammalian retinal ganglion cell neurons in culture. The neurotransmitter acetylcholine (ACh) can be detected in the medium of many of these retinal cultures, after release presumably from the choline acetyltransferase-positive amacrine cells. The postsynaptic effect of endogenous or applied ACh on the ganglion cells can be blocked with specific nicotinic antagonists. Here it is shown that within 24 hours of producing such a pharmacologic blockade, the retinal ganglion cells begin to sprout or regenerate neuronal processes. Thus, the growth-enhancing effect of nicotinic antagonists may be due to the removal of inhibition to growth by tonic levels of ACh present in the culture medium. Since there is a spontaneous leak of ACh in the intact retina, the effects of nicotinic cholinergic drugs on process outgrowth in culture may reflect a normal control mechanism for growth or regeneration of retinal ganglion cell processes that is exerted by ACh in vivo.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lipton, S A -- Frosch, M P -- Phillips, M D -- Tauck, D L -- Aizenman, E -- EY05477/EY/NEI NIH HHS/ -- EY06087/EY/NEI NIH HHS/ -- NS00879/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 1988 Mar 11;239(4845):1293-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Division of Neuroscience, Children's Hospital, Boston, MA 02115.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3344435" target="_blank"〉PubMed〈/a〉

    Neuronal apoptosis versus necrosis induced by glutamate or free radicals (1996)

    Notes: Abstract The type of cell death encountered in neuronal cell cultures exposed to excitatory amino acids — such as glutamate, the major excitatory neurotransmitter in the central nervous system, or free radicals, such as nitric oxide (NO.) and superoxide anoin (O2. −), which react to form peroxynitrite (ONOO−) — appears to depend on the intensity of the exposure and may involve two temporarily distinct phases. Following relatively fulminant insults, an initial phase of necrosis — associated with extreme energy depletion — may simply reflect the failure of neurons to carry out the ‘default’ apoptotic death program used to efficiently dispose of aged or otherwise unwanted cells. Neurons recovering mitochondrial energy potential after an initial fulminant insult or following a more subtle inciting injury may subsequently undergo apoptosis, possibly associated with a factor released from mitochondria that triggers this death program. The maintenance of balanced energy production may be a decisive factor in detemining the degree, type, and progression of neuronal injury caused by ‘excitotoxins’ and free radicals. Similar events could possibly occur in vivo after ischemia or other insults.
