Figure 2From: Mediation of exogenous hydrogen sulfide in recovery of ischemic post-conditioning-induced cardioprotection via down-regulating oxidative stress and up-regulating PI3K/Akt/GSK-3β pathway in isolated aging rat hearts H 2 S production rate and CSE expressions. The H2S production rate (A and C). The expression of CSE protein (B and D). The intensity of each band was quantified by densitometry, and data were normalized to the GAPDH signal. All data were from four independent experiments. * p < 0.05 vs. control group; # p < 0.05 vs. I/R group.Back to article page
