Fig 4. NaHS decreased TGF-β1-stimulated overexpression of phosphorylated ERK1/2.

Fig 4

(A) HK-2 cells were incubated with TGF-β1 for several specific time periods, and the phosphorylated ERK1/2 was detected by western blot assay. (B) Western blot assay for phospho-ERK1/2 expression in HK-2 cells. Pretreatment by the several concentrations of NaHS is given to HK-2 cells for 12 hours and then TGF-β1 was given to the cells for 30 minutes at which time the phosphorylated ERK1/2 express the most (C) Graphical representation of the relative quantification for phospho-ERK1/2. The relative values were calculated by the density of phospho-ERK1/2 vs GAPDH (%). The values of mean ± SEM (n = 3) were gained from relative abundance quantified by densitometry and normalized to GAPDH. #P<0.05 vs. control group, *P<0.05 vs TGF-β1 group. One-way ANOVA followed by Tukey’s multiple comparison test.
