Integration of the Mitochondrial and Death Receptors (DRs) Pathways and Role of c-FLIP

Two major signaling pathways, the intrinsic or mitochondrial pathway and the extrinsic or cell surface DRs pathway, regulate apoptosis (Fig. 1) (Lavrik et al. 2005; Micheau and Tschopp 2003; Safa et al. 2008). In the intrinsic pathway, various anti- and pro-apoptotic members of the Bcl-2 family form an interactive network that finally regulates the release of apoptosis-triggering factors such as cytochrome c, apoptosis-inducing factors including Smac/DIABLO, HtrA2/Omi, and Endonuclease G (endoG) from the mitochondria to the cytosol (Vaux 2011; Plati et al. 2011). Upon release, cytochrome cand dATP bind to apoptotic proteinase-activating factor-1 (Apaf-1), and this complex along with adenine nucleotides forms the apoptosome and promotes procaspase-9 autoactivation...
