Role of cytochrome c in apoptosis
WebWhen mitochondria are involved in the apoptotic mechanism, cytochrome c represents the critical link that communicates changes in mitochondrial permeability with activation of cytosolic procaspases. Cytochrome c activates caspases through its effects on a protein called apoptosis protease-activating factor-1 (Apaf-1). WebCytochrome c is highly water-soluble, unlike other cytochromes. It is capable of undergoing oxidation and reduction as its iron atom converts between the ferrous and ferric forms, but does not bind oxygen. It also plays a …

As mentioned in the introduction, release of cytochrome c from mitochondria into the cytosol is considered a sign of apoptosis in several plants (Sun et al. 1999). For this reason, we tested release of cytochrome c from the mitochondria in the presence of FA by Western blot analysis (Fig. 8).
Web28 Mar 2024 · The proteins Bcl-2 and Bcl-X L prevent apoptosis, but their mechanism of action is unclear. We examined the role of Bcl-2 and Bcl-X L in the regulation of cytosolic Ca 2+, nitric oxide production (NO), c-Jun NH 2-terminal kinase (JNK) activation, and apoptosis in Jurkat T cells.Thapsigargin (TG), an inhibitor of the endoplasmic reticulum-associated … WebCytochrome c is a signaling molecule essential for apoptotic cell death released from mitochondria to the cytosol allowing the interaction with protease, as the apoptosis protease activation factor, which lead to the activation of factor-1 and procaspase 9.
