Autophagy in cardiomyocytes was upregulated by hypoxia/reoxygenation (H/R).
H2S inhibited autophagy in cardiomyocytes exposed to H/R significantly.
PI3K/SGK1/GSK3β signaling pathway is involved in the anti-autophagy effect of H2S.
The cardioprotection of H2S attributed partly to its anti-autophagy property.
