Abstract excerpt
SH-SY5Y cells transfected with the enzymatically inactive Cu,Zn superoxide dismutase mutant H46R were more resistant to S-nitrosoglutathione (GSNO)-induced apoptosis. Cytochrome c release from mitochondria, caspase 3 activation, p53 up-regulation, p21 cleavage and Bcl-2 modulation, all involved in the apoptotic process, were significantly less altered with respect to untransfected cells. The H46R resistance to NO...
