Fig. 5From: Cilastatin protects against tacrolimus-induced nephrotoxicity via anti-oxidative and anti-apoptotic propertiesEffect of CL on proximal tubular cells with TAC treatment. a Viability of HK-2 cells in TAC treatment with or without CL cotreatment. Note that CL cotreatment improved cell viability in TAC-treated cells. b Evaluation of apoptosis using FITC–annexin V staining followed by flow cytometry and graphing showed that the mean percentage of annexin V-positive cells was decreased in the TAC + CL group as compared to the TAC group. #P < 0.05 vs. VH; @P < 0.05 vs. TACBack to article page
