Fas-driven apoptosis in Jurkat cells results in the inactivation of cytochrome c with cessation of oxygen consumption. Overexpression of Bcl-2 was found to protect against acidification and apoptosis mediated by Fas ligation in these cells. Bcl-2 is present in the outer mitochondrial membrane, but the molecular mechanism by which it protects cells is unknown. Because Bcl-2 projects into the mitochondrial intermembrane space and cytochrome c is located in the intermembrane space, we considered the possibility that Bcl-2 might protect cytochrome c from inactivation during Fas-mediated apoptosis. The present study shows that 1) in Jurkat cells, cytochrome c inactivation during Fas-driven apoptosis requires the permeabilization of the outer mitochondrial membrane; and 2) the post-mitochondrial fraction from CEM cells that overexpress Bcl-2 both prevents and reverses cytochrome c inactivation.
