The effect of exogenous H2S on the expression of apoptotic relative factors. a Cleaved caspase-9; b Cleaved caspase-3; c Cyt c; d Bcl-2. The intensity of each band was quantified by densitometry, and data were normalized to the GAPDH signal. The expression levels in the control group were considered the basal levels, and the others are expressed as fold change from the control group. The fold change values represent the mean ± S.E.M. of four determinations. *p < 0.05, **p < 0.01 vs. control group; #p < 0.05 vs. H/R group; &&p < 0.01 vs. PC group; $p < 0.05 vs. H/R + NaHS group
