Figure 1: Protective effect of SM on UVB radiation-induced mitochondrial membrane potential (Δψm) alteration in HDFa. Δψm changes were observed under a fluorescence microscope after Rh-123 (bright red and green color) staining. UVB exposure increased loss of Δψm and emitted green fluorescence. SM treatment (8, 40 and 80 µM) before UVB exposure improved membrane potential loss and emitted red fluorescence. The percentage of fluorescence intensity was increased in a dose-dependent manner. values are given as means ± SD of three experiments in each group. values not sharing a common marking (a, b, c, …) differ significantly at P<0.05 (DMRT), (a) Control, (b) SM (80μM), (c) UVB-irradiation, (d) UVB + SM (8μM), (e) UVB + SM (40μM), (f) UVB + SM (80 μM)
