Abstract:

Ginsenoside Rg1 exerts a beneficial effect in many kidney diseases. But little work has been done to confirm whether ginsenoside Rg1 could also exert a protective effect on anti-glomerular basement membrane (anti-GBM) glomerular nephritis (GN). We aimed to explore the role of ginsenoside Rg1 in attenuating anti-GBM GN in vitro and in vivo and investigate the mechanism under its action.Interleukin-1β (IL-1β) treated podocytes were used as a cell model. A total of 20 mice were used to build the Anti-GBM GN mice model. Real-time PCR analysis (RT-PCR), Western blot analysis and ELISA assay were conducted to detect related indicators in this study. The statistical analysis was performed using GraphPad Prism software 6.0.Ginsenoside Rg1 attenuates IL-1β-induced inflammation and apoptosis in podocytes. NRF2 expression can be inhibited by IL-1β, whereas reversed by ginsenoside Rg1. NRF2 inhibitor ML385 can significantly reverse the effects of ginsenoside Rg1 on inflammation and apoptosis induced by IL-1β, and block the inhibitory effect of ginsenoside Rg1 on IL-1β activated MAPK pathway. In addition, ginsenoside Rg1 could improve anti-GBM GN injury.Ginsenoside Rg1 inhibits the anti-GBM GN damage through regulating NRF2 pathwayand. Our findings provide new insight and mechanism of ginsenoside Rg1 to prevent anti-GBM GN.
