Cytochrome c plays a crucial role in the mitochondrial electron transport chain and can be used as a biomarker to measure mitochondrial damage and various diseases. The level of cytochrome c in the bloodstream is associated with cellular diseases and can be used to predict disease progression by analyzing serum samples.
In mitochondrial electron transport chain (ETC), cytochrome c (water-soluble heme metalloprotein) transfers the electrons between cytochrome c reductase (CcR) and cytochrome c oxidase (CcO). Recently it was reported that cytochrome c acts as an in-vivo biomarker for mitochondrial damage, resuscitation, cardiac arrest, organ injury & various kinds of cancers. All these observations provide significant importance to measure the cytochrome c. Cytochrome c also acts as a mediator biomolecule of DNA damage response by its release in the cytoplasm by the mitochondria to enhance the apoptosis. Under various pathological conditions, low level or high level of cyto-chrome c in bloodstream can lead to various diseases at the cellular level. Diagnosis of cytochrome c levels in serum samples of patients may help to predict earlier stages as well as the severity of the disease. In healthy persons, the normal level of cytochrome c is 39.8 ng/mL. This proposed review article explains various fabricated methods for the detection of cytochrome c with their principle, merits, and demerits.
