BACKGROUND: Although PPARgamma antagonists have shown considerable pre-clinical efficacy, recent studies suggest PPARgamma ligands induce PPARgamma-independent effects. There is a need to better define such effects to permit rational utilization of these agents. METHODS: We have studied the effects of a range of endogenous and synthetic PPARgamma ligands on proliferation, growth arrest (FACS analysis) and apoptosis (caspase-3/7 activation and DNA fragmentation) in multiple prostate carcinoma cell lines (DU145, PC-3 and LNCaP) and in a series of cell lines modelling metastatic transitional cell carcinoma of the bladder (TSU-Pr1, TSU-Pr1-B1 and TSU-Pr1-B2). RESULTS: 15-deoxy-prostaglandin J2 (..
