描述
Coenzyme Q functions as an electron carrier and reversibly changes to either an oxidized (CoQ), intermediate (CoQ), or reduced (CoQH2) form within a biomembrane. The Coenzyme Q2 (CoQH2) form also acts as an antioxidant and prevents cell death, and thus has been successfully used as a supplement. On the other hand, the value of the CoQ/CoQH2 ratio has been shown to increase in a number of diseases, presumably due to an anti-proliferative effect involving CoQ. Induction of apoptosis by CoQ2 is dependent on p53 protein levels. Moreover, CoQ2 induces reactive oxygen species (ROS) and the phosphorylation of p53. An antioxidant, l-ascorbic acid, inhibited CoQ2-induced p53 phosphorylation and further apoptotic stimuli. (PMID: 15905035) [HMDB]
