μa. Upper: LC3 Western blot. At steady state, LC3-II levels normalized to GAPDH decreased in both DMSO and SAHA groups after 2 hours of ischemia plus 2 hours of reperfusion (I2hR2h). However, after Bafilomycin A treatment, SAHA treatment induced increases in LC3II levels after simulated I/R (n=3, p<0.05). Lower: Quantification. b. LDH cell death assay. SAHA treatment (2μM) reduced cell death around 20% after sI/R (5 hour/1.5 hour) (n=3, p<0.05). Suppression of ATG7 abolished SAHA's cardioprotective effects after sI/R (n=3, p<0.05).
