Abstract:Objective: To investigate the influence of fasudil on the proliferation and fibrosis of human renal tubular epithelial cells incubated with high glucose. Methods: HK-2 cells were divided into normal control group (D-glucose 5.5 mmol/L), high tension group (D-glucose 5.5 mmol/L+54.5 mmol/L mannitol), high glucose group (D-glucose 60 mmol/L), high glucose+fasudil treatment group (the concentrations of fasudil were 5, 10 and 20 μmol/L). Cell proliferation was assessed with MTT assay. Changes in the p-MYPT1-Thr853 were detected with co-immunoprecipitation assay. The expression of connective tissue growth factor (CTGF) was detected with western blot, the protein content of transforming growth factor-β1 (TGF-β1) and fibronectin (Fn) in the supernatant were detected by ELISA. Results: Compared with normal control group, cell proliferation and the expression of p-MYPT1-Thr853, TGF-β1, CTGF and Fn were significantly increased in high glucose group. Compared with high glucose group, cell proliferation and the expression of p-MYPT1-Thr853, TGF-β1, CTGF and Fn were significantly decreased in fasudil treatment group. Conclusion: Fasudil can inhibit high glucose-induced proliferation and fibrosis of HK-2 and it may produce effect through the inhibition of Rho kinase activity.
