7.Cytochrome C、mitochondria and apoptosis
Chinese Pharmacological Bulletin 1987;0(03):-
There is an evidence that mitochondrial cytochrome C has dual functions in controlling both cellular energetic metabolism and apoptosis. Once released, cytochrome C, in interaction with apoptotic protease activating factors (Apaf 1), initiates the activation of the execution caspases that lead to the subsequent apoptosis. Release of cytochrome C is the result of a perturbation of mitochondrial membrane permeability. Anti apoptotic Bcl 2 family proteins function as gatekeepers to prevent the release of cytochrome C. In addition to cytochrome C, mitochondria release other apoptogenic proteins including apoptosis inducing factor (AIF) during apoptosis. These two pathways may work together to induce complete apoptosis. After transient cerebral ischemia, the release of cytochrome C occurs from mitochondria, preceding DNA fragmentation.
