Effect of PPARα agonist fenofibrate (A) and PPARγ agonist pioglitazone (B) on osteoprotegerin (OPG) release from MC3T3-E1 preosteoblast cells. Amount of OPG is related to the amount of total protein in each sample. Data is presented in mean ± SD in % of control (unstimulated cells) from two parallels, and the figure represents data from four different experiments. *P < 0.05, **P < 0.01, ***P < 0.001 significantly different compared to control.
