Peroxisome proliferator activated receptors (PPAR)s are nuclear transcription factors of the steroid receptor super-family. One member, PPARγ, a critical transcription factor in adipogenesis, is expressed in ECV304 cells, and when activated participates in the induction of cell death by apoptosis. Here we describe a clone of ECV304 cells, ECV-ACO.Luc, which stably expresses a reporter gene for PPAR activation. ECV-ACO.Luc respond to the PPARγ agonists, 15-deoxy-Δ12,14 PGJ2, and ciglitizone, by inducing luciferase expression. Furthermore, using ECV-ACO.Luc, we demonstrate that a newly described PPARγ antagonist, bisphenol A diglycidyl ether (BADGE) has agonist activities. Similar to 15-deoxy-Δ12,14 PGJ2, BADGE induces PPARγ activation, nuclear localization of the receptor, and induces cell death.
