Abstract

The peroxisome proliferator-activated receptor (PPAR) γ is one member of the nuclear receptor superfamily that contains in excess of 80 described receptors. PPARγ activators are a diverse group of agents that range from endogenous fatty acids or derivatives (linolenic, linoleic, and 15-deoxy-Δ 12,14-prostaglandin J 2) to Food and Drug Administration-approved thiazolidinedione drugs [pioglitazone (Actos) and rosiglitazone (Avandia)] for the treatment of diabetes, Once activated, PPARγ will preferentially bind with retinoid X receptor α and signal antiproliferative, antiangiogenic, and prodifferentiation pathways in several tissue types, thus making it a highly useful target for down-regulation of carcinogenesis. Although PPAR-γ activators show many anticancer effects on cell lines, their advancement into humen advanced cancer clinical trials has met with limited success. This article will review translational findings in PPARγ activation and targeting in carcinogenesis prevention as they relate to the potential use of PPARγ activators clinically as cancer chemoprevention strategies.
