Expression of peroxisome proliferator‐activated receptor (PPAR) in human prostate cancer

Recent studies have demonstrated that peroxisome proliferator activator‐receptors (PPAR)‐γ is expressed in some cancer cells such as breast, lung, and gastric cancer, and its ligand induces growth arrest of these cancer cells through apoptosis. However, the expression and localization of PPARs in prostate have not been examined. In this study, PPARs expression was investigated in human prostate cancer (PC), prostatic intraepithelial neoplasia (PIN), benign prostatic hyperplasia (BPH), and normal prostate (NP) tissues.
