Fig. 5

(A) The inhibitory effects of TDAG51 on the promoter activity of aP2-Luc induced by PPARγ-RXRα coexpression. Reporter plasmids (aP2-Luc [0.1 µg] and pcDNA3.1/His/LacZ [0.1 µg]) were cotransfected with epitope-tagged expression plasmids (Flag-PPARγ [0.25 µg], Myc-RXRα [0.1 µg], and/or Xp-TDAG51 [0.25-0.5 µg]) into 293T cells. The expression of transfected plasmids was analyzed by immunoblotting against anti-epitope antibodies. β-Actin was used as the loading control. (B) The inhibitory effects of TDAG51 on the promoter activity of aP2-Luc induced by PPARγ expression with rosiglitazone treatment. (C) The inhibitory effects of TDAG51 deletion mutants on the promoter activity of aP2-Luc induced by PPARγ-RXRα coexpression. Reporter plasmids were cotransfected with epitope-tagged expression plasmids (Flag-PPARγ [0.25 µg], Myc-RXRα [0.1 µg], and/or GST-TDAG51 [0.5 µg]) into 293T cells. GST alone (mock) was used as a control. **P < 0.01; ***P < 0.001; n.s., not significant.
