Abstract
Based on the binding between peroxisome proliferators-activated receptor γ (PPARγ) and steroid receptor co-activator-1 (SRC-1), an enzyme-linked immunosorbent assay (ELISA) was used to screen new PPARγ ligands from various benzylidinethiazole derivatives, which have anti-inflammatory activity. Among those derivatives, 5-(3,5-di-tert-butyl-4- hydroxybenzylidene) thiazolidine-2,4-dione (BTZD) increased the binding between PPARγ and SRC-1. BTZD was found to induce adipogenesis and PPARγ trans-activation in 3T3-L1 pre-adipocyte, and increased the binding between PPARγ and SRC-1 in in vitro binding assay and complex consisting of PPARγ and SRC-1 in the co-immunoprecipitaion. Chromatin immunoprecipitation (ChIP) analysis revealed that BTZD induced the binding of PPARγ-SRC-1 complex to PPAR response element (PPRE) in the same pattern of other PPARγ ligand. From these studies, we have identified and studied the function of a new PPARγ ligand, BTZD. We suggest that BTZD can be used as a modulator of PPARγ. This study applying ELISA and ChIP assay can offer new methods to screen PPARγ ligand and understand the effects of PPARγ ligands on inflammation.
