| abstractText | Silent mating type information regulation 2 homolog 3 (SIRT3) is a major protective mediator that ameliorates oxidative stress and mitochondrial dysfunction, which are associated with the pathogenesis of epithelial-mesenchymal transition (EMT). The present study was aimed to investigate the potential role of SIRT3 in renal tubular EMT both in vitro and in vivo. Firstly, we showed that the expression of SIRT3 was repressed in angiotensin II-induced EMT. SIRT3 deficiency triggered EMT response, while over-expression of SIRT3 attenuated EMT response. In addition, over-expression of SIRT3 repressed Ang-induced excessive production of mitochondrial superoxide, as well as mitochondrial dysfunction evidenced by the maintenance of mitochondrial number and morphology, and the stabilization of mitochondrial membrane potential. In conclusion, these findings identify a protective role of SIRT3 against angiotensin II-induced EMT in the kidney, and suggest SIRT3 upregulation is a potential therapeutic strategy for the treatment of renal tubulointerstitial fibrosis. |
