Cellular redox regulation and prooxidant signaling systems: a new perspective on the free radical theory of aging.

Abstract

The overarching role of coenzyme Q(10) in gene regulation, bioenergy formation, cellular redox poise regulation, and hydrogen peroxide formation is presented. Coenzyme Q(10) has a central role acting as a prooxidant in the generation of H(2)O(2). Contrary to the dogma that superoxide and H(2)O(2) formation are highly deleterious to cell survival this… (More)
