Objective To investigate the effects of 5-Aza-CdR( methylation transferase inhibitor) on the expression levels of leptin gene in chondrocytes and methylation states of leptin promoter region between osteoarthritis (OA) group and control. Methods The chondrocytes in osteoarthritis group were treated with 5-Aza-CdR with different doses and time-points, and the expression level of leptin was detected by real-time polymerase chain reaction for picking up the optimum dose and time-point. Next, the chondrocytes in 5 osteoarthritis patients and 5 control patients (amputation due to severe trauma) were treated with 5-Aza-CdR. Lastly, leptin mRNA expression levels in the four groups osteoarthritis and control chondrocytes treated with/without 5-Aza-CdR were measured by real-time PCR and the methylation state of promoter region ( - 280- + 79) was detected by epityper quantitative DNA methylation analysis. Results ( 1 ) After treating the chondrocytes in OA groups with 10 μmol/L 5-Aza-CdR for 72 h, the mRNA expression levels of leptin were increased significantly. ( 2 ) The mRNA expression levels of leptin were significantly different among the four groups ( P ＜ 0. 05 ), and the chondrocytes in osteoarthritis groups treated with 5-Aza-CdR showed a marked induction of leptin mRNA expression. (3) Analysis of quantitative methylation data using an unsupervised hierarchical clustering algorithm, showed that methylation patterns of leptin promoter was different between control and osteoarthritis chondrocyte treated with/without 5-Aza-CdR. Conclusion Demethylation of leptin promoter might up-regulate leptin gene expression level and it might contribute to osteoarthritis.

Neovascularization is one of the early pathologic changes of rheumatoid arthritis(RA)synovium and is the major players in the promotion and perpetuation of pannus.Endostatin has antiangiogenic effect via inhibition of endothelial cell proliferation,migration and induction of apoptosis.The inhibition of angiogenesis in synovium by endostatin appears to be a promising means for the future treatment of RA.Also,endostatin has a therapeutic effect on RA by the inhibition of proliferation and induction of apoptosis in fibroblast-like synoviocytes.
