WISP1 decreases PPARγ transcriptional activity. (a) Increasing amounts of expression vector for WISP1 (0.2, 0.4, 0.8 µg) were transfected into HEK or MEF cells along with 0.1 µg of PPRE-TK-Luc and 0.02 µg of an RSV-β-galactosidase construct as an internal control, alone or in combinations with 0.1 µg of PPARγ expressing vector. (b) Increasing amounts of WISP1 (0.2, 0.4, 0.8 µg) were transfected into HEK and MEF cells along with 0.1 µg of UAS-TK-Luc and 0.02 µg of an RSV-β-galactosidase construct as an internal control, alone or in combination with 0.1 µg of an expression vector for the Gal4-PPARγ-LBD fusion protein. Five hours after transfection, cells were treated (black bars) or not (open bars) with 1 µM rosiglitazone for 24 hours and assayed for luciferase and β-galactosidase activities. The results represent the average of at least three independent experiments each done in triplicate. Results are presented as means ± SEM; *p < 0.05; **p < 0.01; ***p < 0.005.
