Fig. 6

Exogenous H2S inhibited PERK-eIF 2α-ATF 4 pathway. a PERK; b eIF 2α; c ATF 4; d ATF 6. The graphs represent the optical density of the bands of phosphorylated PERK and eIF 2α normalized with the expression of total PERK and eIF 2α, respectively. The graphs represent the optical density of the bands of ATF 4 and ATF 6 normalized with the expression of 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 three determinations. *p < 0.05, **p < 0.01 vs. control group; #p < 0.05, ##p < 0.01 vs. H/R group; &&p < 0.01 vs. PC group; $p < 0.05 vs. H/R + NaHS group
