Figure 4. Hydrogen sulfide (H2S) regulated the expression of apoptosis-related proteins. A, Representative immunoblots showing the expression of Bax, Bcl-2, and activated caspase 3 p17 in the H9c2 cells. Bax (B) and Bcl-2 (C) expression normalized to GAPDH (n=6). D, Densitometric analysis of the ratio of Bcl-2 to Bax. E, Activated caspase 3 p17 expression normalized to GAPDH. Data are reported as means±SE (n=6) (ANOVA followed by Student-Newman-Keuls post hoc test). NS: not significant.
