title: Bisphenol a diglycidyl ether (BADGE) suppresses tumor necrosis factor-alpha production as a PPARgamma agonist in the murine macrophage-like cell line, RAW 264.7.
abstract: Bisphenol A diglycidyl ether (BADGE) is a newly described peroxisome proliferator-activated receptor gamma (PPARgamma) antagonist in adipogenic cells. In contrast, in the macrophage-like cell line RAW 264.7, BADGE, like the PPARgamma agonist pioglitazone hydrochloride, not only increased promoter activity of the PPARgamma-luciferase reporter gene, but also suppressed lipopolysaccharide (LPS)-induced tumor necrosis factor-alpha (TNF-alpha) production. These results suggest that BADGE is a PPARgamma agonist in RAW 264.7 cells. Furthermore, overexpression of the coactivator p300 restored BADGE- or pioglitazone hydrochloride-suppressed promoter activity of the nuclear factor-kappa B (NF-kappaB)-luciferase reporter gene, suggesting that PPARgamma may interfere with NF-kappaB transcriptional activity via coactivator competition.
