HeLa cells were transfected with the reporter construct (AcoA.TK.CAT or pCAT-promIBABP), and full-length mPPARα, mPPARβ, mPPARγ, or hFXR expression plasmids. They were then treated for 36 h with specific ligands and increasing concentrations of SR-202 as indicated. Each bar represents the mean ± sem of three experiments. CAT values were normalized to the β-galactosidase activity resulting from the expression of a cotransfected vector.

3. Fig. 3. SR-202 Is a Potent Antagonist of PPARγ-Induced Adipocyte Differentiation A, Effect of SR-202 on BRL induced adipogenesis of 3T3-L1 cells. Cells were pretreated with SR-202 or vehicle (water) for 24 h and then treated with BRL (25 nm) and insulin (5 μg/ml), with or without SR-202. After 6 d of treatment, cells were stained with Oil Red O. B, Effect of SR-202 on hormone-induced adipocyte differentiation of 3T3-L1 cells. Cells were pretreated with SR-202 and then induced with dexamethasone/IBMX/Ins with or without SR-202 for 2 d. Thereafter, the medium was changed to insulin alone with or without SR-202 for an additional 2 d. Cells were then stained with Oil Red O. C, Effect of SR-202 on the mRNA levels of aP2 adipocyte differentiation marker. Ribonuclease protection assay was performed on 10 μg of total RNA from 3T3-L1 cells treated as indicated above.

SR-202 Prevents Weight Gain and Adipose Tissue Deposit Content in Mice Body weight (A) and fat weight (B and C) of wt and PPARγ +/− male mice treated or not with SR-202 (400 mg/kg) under both SD and HFD. SR-202 was given as food admixture and the treatment was started just after weaning during a consecutive 10 wk. Each bar represents the mean ± sem of at least 10 mice per group (* and $, P < 0.05; NS, no significative difference). *, Comparison between CTL and SR-202-treated mice; $, comparison between SD and HFD.

6. Fig. 6. SR-202 Decreases PPARγ Activity in Vivo Amounts of the mRNA of the following PPARγ target genes were determined in WAT of wt and PPARγ +/− mice under HFD treated or not with SR-202: LPL, FAT/CD36, aP2, and SREBP-1c. The mRNA level of each target was determined by reverse transcription followed by real-time PCR using the Light-cycler-FastStart DNA Master SYBR Green I as described in Materials and Methods. Each bar represents the mean ± sem (n = 5). *, P < 0.05 (comparison with CTL wt mice).
