Bcl-2 inhibits most types of apoptotic cell death, implying a common mechanism of lethality. Bcl-2 is localized to intracellular sites of oxygen free radical generation including mitochondria, endoplasmic reticula, and nuclear membranes. Antioxidants that scavenge peroxides, N-acetylcysteine and glutathione peroxidase, countered apoptotic death, while manganese superoxide dismutase did not. Bcl-2 protected cells from H2O2- and menadione-induced oxidative deaths. Bcl-2 did not prevent the… CONTINUE READING
