Abstract |
The reduced bone mineral density (BMD) observed in osteoporosis results, in part, from reduced activity of bone-forming osteoblasts. We examined the effect of peroxisome proliferator-activated receptor (PPAR) activators on MC3T3-E1 preosteoblast maturation. Activators of PPARalpha, delta and gamma induced alkaline phosphatase activity, matrix calcification and the expression of osteoblast genes as determined by reverse transcriptase-polymerase chain reaction. However, at relatively high concentrations of the specific PPARgamma ligands, ciglitazone and troglitazone, maturation was inhibited. PPARalpha, delta and gamma1 were expressed in MC3T3-E1 cells. PPARgamma1 mRNA and protein levels were induced early during osteoblastic maturation. We speculate that endogenous and pharmacological PPAR activators may affect BMD by modulating osteoblastic maturation. |
