Effects of resveratrol on cell proliferation in glomerular mesangial cells cultured under high glucose by inhibiting SphK1/AP-1 signal pathway / 中国药理学通报

ABSTRACT

Aim To observe the expression of FN and TGF-β1 in the glomerular mesangial cells induced by high-glucose after the intervention of resveratrol, and further discuss its influence on SphK1/AP-1 signaling pathway. Methods The rat glomerular mesangial cells induced by high glucose were used to observe the effects of resveratrol on cell proliferation after interven-tion. The survival vitality and proliferation of glomeru-lar mesangial cells were determined by MTT, and then FN, TGF-β1 and SphK1 protein expression were deter-mined by Western blot. Also, AP-1 activity was deter- mined by EMSA assay. Results Resveratrol could obviously inhibit the proliferation of high glucose-in-duced glomerular mesangial cells, lower SphK1 expres-sion, inhibit AP-1 activity and thus inhibit the expres-sion of FN, TGF-β1. Conclusions Resveratrol inhib-its the proliferation of high glucose-induced glomerular mesangial cells, which may be closely related to the in-hibition of SphK1/AP-1 signaling pathway.
