Although the role of cytochrome c in apoptosis is well established, details of its participation in signaling pathways in vivo are not completely understood. ... The knockout for the somatic isoform of cytochrome c caused embryonic lethality in mice, but derived embryonic fibroblasts were shown to be resistant to...

This study analyses the relationship of cytochrome c oxidase (COX)-deficient neurones with the neuropathological markers of AD, neurofibrillary tangles (NFTs) and amyloid plaques, as well as markers of neuronal apoptosis known to occur in AD brains.

In stress-mediated apoptosis, a cytosolic DISC equivalent, the apoptosome is formed that activates the effector caspases. We have characterised this complex in THP.1 cells, and shown that this is a cytochrome c dependent process that induces the formation of an approximately 700 kDa apoptosome caspase processing complex.

The release of cytochrome c from mitochondria is necessary for the formation of the Apaf-1 apoptosome and subsequent activation of caspase-9 in mammalian cells. However, the role of cytochrome c in caspase activation in Drosophila cells is not well understood.

Apaf-1 plays a critical role in apoptosis by binding to and activating procaspase-9. ... The product of this Apaf-1 cDNA activated procaspase-9 in a cytochrome c and dATP/ATP-dependent manner. We used this Apaf-1 to show that Apaf-1 requires dATP/ATP hydrolysis to interact with cytochrome c, self-associate and bind to...
