| Cytochrome c ** The term "release of cytochrome c" ** an increase in level for the cytosol. Small hemeprotein found loosely associated with the inner membrane of the mitochondrion where it plays a critical role in cellular respiration. Cytochrome 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 major role in cell apoptosis. The term "release of cytochrome c" refers to a critical step in the process of programmed cell death, also known as apoptosis. In its new location—the cytosol—cytochrome c participates in the apoptotic signaling pathway by helping to form the apoptosome, which activates caspases that execute cell death. Cytochrome c is a small protein normally located in the mitochondrial intermembrane space. Its primary role in healthy cells is to participate in the electron transport chain, a process that helps produce energy (ATP) through oxidative phosphorylation. Mitochondrial outer membrane permeability leads to the release of cytochrome c from the mitochondria into the cytosol. The release of cytochrome c is a pivotal event in apoptosis where cytochrome c moves from the mitochondria to the cytosol, initiating a chain reaction that leads to programmed cell death. On the one hand, cytochrome c can promote cancer cell survival and proliferation by regulating the activity of various signaling pathways, such as the PI3K/AKT pathway. This can lead to increased cell growth and resistance to apoptosis, which are hallmarks of cancer. On the other hand, cytochrome c can also induce apoptosis in cancer cells by interacting with other proteins, such as Apaf-1 and caspase-9. This can lead to the activation of the intrinsic apoptotic pathway, which can result in the death of cancer cells. Overexpressed in Breast, Lung, Colon, and Prostrate. Underexpressed in Ovarian, and Pancreatic. |
