Cytochrome c role in apoptosis
WebFeb 21, 1997 · The increase in cytosolic holocytochrome c upon apoptosis suggests that mitochondria may participate in apoptosis by releasing cytochrome c. This observation raises the possibility that Bcl-2, located on the outer membrane of mitochondria, may prevent cell death by blocking the release of cytochrome c. WebJan 27, 2024 · However, the roles of apoptosis are still perplexing and complex, with multiple pro- and anti-death factors underlying the diversity of events (Everett and McFadden, 1999; Rudel et al., 2010).
