A central role for S-nitrosylation in apoptosis

Moran Benhar & Jonathan S. Stamler

Nitric oxide (NO) has long been known to mediate cell death, best exemplified in cellular models of endotoxic shock and NMDA-induced neurodegeneration. Cell death was initially presumed to be the result of NO reacting with superoxide, generating toxic peroxynitrite.
