Collaborative Power of Nrf2 and PPAR gamma Activators against Metabolic and Drug-Induced Oxidative Injury

초록

Mammalian cells have evolved a unique strategy to protect themselves against oxidative damage induced by reactive oxygen species (ROS). Especially, two transcription factors, nuclear factor erythroid 2p45-related factor 2 (Nrf2) and peroxisome proliferatoractivated receptor gamma (PPAR gamma), have been shown to play key roles in establishing this cellular antioxidative defense system. Recently, several researchers reported ameliorating effects of pharmacological activators for these Nrf2 and PPAR gamma pathways on the progression of various metabolic disorders and drug-induced organ injuries by oxidative stress. In this review, general features of Nrf2 and PPAR gamma pathways in the context of oxidative protection will be summarized first. Then, a number of successful applications of natural and synthetic Nrf2 and PPAR gamma activators to the alleviation of pathological and drug-related oxidative damage will be discussed later.
