Effect of PPARγ ligands on TSU-Pr1 cell number. Cells were treated with ligand either alone or in the presence of 10 μM GW9662 at Day 0. A, Troglitazone (100 μM; TGZ) and ciglitazone (40 μM; CGZ). B, Rosiglitazone (10 μM; RGZ) and pioglitazone (20 μM; PGZ). C, 15-deoxy-prostaglandin J2 (15dPGJ2) 5.6 μM and 10 μM. Values are mean ± SEM of 2–3 experiments performed in triplicate expressed as percent control. Statistical significance * P < 0.01 (ANOVA followed by Dunnett post test).
