With respect to the nervous system, HNO donors have been shown to attenuate NMDA receptor activity and neuronal injury, suggesting that its production may be protective against cerebral ischemic damage. Hence, we studied the effect of the classical HNO\u2010donor, Angeli\u2019s salt (AS), on a cerebral ischemia\/reperfusion injury in a mouse model of experimental stroke and on related<jats:italic>in vitro<\/jats:italic>paradigms of neurotoxicity. I.p. injection of AS (40\u2003\u03bcmol\/kg) in mice prior to middle cerebral artery occlusion exacerbated cortical infarct size and worsened the persistent neurological deficit. AS not only decreased systolic blood pressure, but also induced systemic oxidative stress<jats:italic>in vivo<\/jats:italic>indicated by increased isoprostane levels in urine and serum.<jats:italic>In vitro<\/jats:italic>, neuronal damage induced by oxygen\u2010glucose\u2010deprivation of mature neuronal cultures was exacerbated by AS, although there was no direct effect on glutamate excitotoxicity. Finally, AS exacerbated oxidative glutamate toxicity \u2013 that is, cell death propagated via oxidative stress in immature neurons devoid of ionotropic glutamate receptors. Taken together, our data indicate that HNO might worsen cerebral ischemia\u2010reperfusion injury by increasing oxidative stress and decreasing brain perfusion at concentrations shown to be cardioprotective<jats:italic>in vivo<\/jats:italic>.<\/jats:p>","DOI":"10.1111\/j.1471-4159.2009.06266.x","type":"journal-article","created":{"date-parts":[[2009,7,10]],"date-time":"2009-07-10T00:17:23Z","timestamp":1247185043000},"page":"1766-1773","source":"Crossref","is-referenced-by-count":27,"title":["Nitroxyl exacerbates ischemic cerebral injury and oxidative neurotoxicity"],"prefix":"10.1111","volume":"110","author":[{"given":"Chi\u2010un","family":"Choe","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jan","family":"Lewerenz","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Gerry","family":"Fischer","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tracy F.","family":"Uliasz","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Michael Graham","family":"Espey","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Friedhelm C.","family":"Hummel","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Stephen Bruce","family":"King","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Edzard","family":"Schwedhelm","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Rainer H.","family":"B\u00f6ger","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Christian","family":"Gerloff","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sandra J.","family":"Hewett","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tim","family":"Magnus","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sonia","family":"Donzelli","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2009,9,3]]},"reference":[{"key":"e_1_2_7_2_1","doi-asserted-by":"crossref","first-page":"248","DOI":"10.2310\/7290.2008.00025","article-title":"Dynamic analysis of the blood\u2010brain barrier disruption in experimental stroke using time domain in vivo fluorescence imaging","volume":"7","author":"Abulrob A.","year":"2008","journal-title":"Mol.
