SIRT3 inhibits Ang II-induced transdifferentiation of cardiac fibroblasts through beta-catenin/PPAR-gamma signaling

摘要

Aims: Cardiac fibrosis is an inevitable process of numerous cardiovascular diseases in which the transdifferentiation of cardiac fibroblasts plays a pivotal role. Sirtuin3 (SIRT3) has been believed to protect against cardiac fibrosis. However, the mechanism underlying this beneficial effect has not yet been elucidated. In this study, we investigated the potential mechanism of SIRT3 on the inhibition of fibroblast-to-myoblast transdifferentiation.
