Role of DNA Methylation in Adipogenesis

Chen, Yii-Shyuan 12 August 2014 (has links)
The increase in the prevalence of obesity and obesity-related diseases has caused greater attention to be placed on the molecular mechanisms controlling adipogenesis. In this study, we studied the role of 5-aza-2'-deoxycytidine (5-Aza-dC), an inhibitor of DNA methylation, on adipocyte differentiation. We found that inhibiting DNA methylation by 5-Aza-dC significantly inhibited adipocyte differentiation whereas promoting osteoblastogenesis. Wnt10a was up-regulated by 5-Aza-dC treatment and it was suggested that Wnt10a might play a vital role in suppressing adipogenesis and promoting osteoblastogenesis by inhibiting DNA methylation. In 3T3-L1 cells, Wnt signaling inhibitor IWP-2 was found to reverse the inhibitory effect of 5-Aza-dC on Adipocyte differentiation, whereas in mesenchymal stem cell line, ST2 cells, IWP-2 treatment reversed the effect of 5-Aza-dC on promoting osteoblastogenesis. These studies will provide a better understanding to the cause and treatment of obesity and bone-related diseases.
