A LDH activity assay showed that 100 mM alcohol can induce the upregulation of LDH expression in hiPSC-CMs 2.5 times (n = 7). B HTS analysis showed that the red-green fluorescence ratio has significantly dropped (n = 7). C The representative immunofluorescence image of JC-1 labeling showed that the green fluorescence expression of hiPSC-CMs significantly increased after treatment with 100-mM alcohol for 2 h. Scale bar = 25 μm. D, E Flow cytometry and quantitative analysis showed that 100-mM alcohol increased early apoptosis of hiPSC-CMs (n = 3). Results are presented as means ± standard error of the mean (**P < 0.01; two-sided Student’s t-test or one-way analysis of variance).
