Effects of rosiglitazone on PPARγ mRNA level in cultured GLCs. A. Relative expression of PPARγ after rosiglitazone (Rosi) treatment for 72 h in different doses. B. Time course of rosiglitazone on PPARγ mRNA level in cultured GLCs. C. Relative expression of PPARγ in cultured GLCs in response to rosiglitazone treatment for 72 h in the presence or absence of GW9662 and hCG. Results are expressed in ratio to β-actin, and presented as means ± SD of six independent experiments. Statistical significances compared to the DMSO control are shown with one asterisk (P < 0.05).
