5.Effect of peroxisome proliferator activated receptor γ agonist on the proliferation and differentiation of rat osteoblasts in vitro
Chinese Journal of Geriatrics 2011;30(3):241-244
Objective To study the effect of rosiglitazone (RSG), the agonist of peroxisome proliferator activated receptor γ (PPARγ), on the proliferation and differentiation of rat osteoblasts and the related mechanisms. Methods The identification of rat primary osteoblasts was performed by alkaline phosphatase (ALP) staining and mineralized nodules. The 3-(4,5)-dimethylthiahiazo (-z-y1)-3,5-di-phenytetrazoliumromide (MTT) assay and p-nitrophenyl phosphate (PNPP) assay were used to observe the effects of different concentrations of RSG on proliferation and differentiation of the osteoblasts. The reverse transcription polymerase chain reaction (RT-PCR) were used to detect the expression of connective tissue growth factor (CTGF) mRNA. The effects of the different concentrations (0,1,2,5,10 and 20 μmol/L) of RSG on TGF-β1-induced CTGF mRNA expression in osteoblasts were detected. Results (1)Different concentrations of RSG could not change the proliferation of osteoblasts (P>0. 05). (2)Compared with control group, all different concentrations of RSG could suppress ALP activity in osteoblasts (P<0. 01 ). (3) RSG suppressed the osteoblats CTGF mRNA expression induced by TGF-β1 in a dose-dependent manner (P<0. 01). Conclusions In vitro, RSG can inhibit the TGF-β1 induced rat osteoblasts CTGF mRNA expression. RSG may play a potential role in preventing the differentiation of the rat osteoblasts.
