Recent findings regarding nitric oxide-induced neuronal apoptosis are reviewed. In particular, the intracellular mechanism on NOC18, a new type of NO donor, -induced apoptosis in human neuroblastoma SH-SY5Y. Upon the induction of apoptosis by NOC18, an increase in caspase-3-like protease activity, but not caspase-1, was observed. Oxyhemoglobin, an NO trapper, blocked the decrease of pro-caspase-2 and the cleavage of PARP by NOC18 in a concentration-dependent manner. Moreover, NO elicited the release of cytochrome c into the cytosol during apoptosis.
