Abstract:

Recent study has showed that Ginsenoside Rg1, the mian active compound of Panax ginseng, could ameliorate oxidative stress and myocardial apoptosis in diabetes mellitus. However, the roles and mechanisms of Rg1 in proliferative diabetic retinopathy (PDR) are still unclear. In the present study, we aimed to investigate the effects of Rg1 on mesenchymal activation of high-glucose (HG) cultured müller cells. High glucose conditions up-regulate MMP-2, MMP-9 and down-regulate TIMP-2, and promote mesenchymal activation in Müller cells. And Rg1 inhibits the HG-induced mesenchymal activation and HG-increased MMP-2 and MMP-9 and HG-decreased TIMP-2 in Müller cells. HG up-regulates Zeb1 and lncRNA RP11-982M15.8, and down-regulates miR-2113, and Rg1 inhibits these effects of HG. Both inhibition of miR-2113 and over-expression of RP11-982M15.8 significantly restored the HG induced mesenchymal activasion. Taken together, our findings suggested that Rg1 inhibited HG-induced mesenchymal activation and fibrosis via regulating miR-2113/RP11-982M15.8/Zeb1 pathway.
