Figure 6. The addition of NAC suppressed cell death and restored the MMP. (A and B) Apoptotic A549 cells transfected with shPRDX5 and Mock A549 cells were detected via Mito-SOX staining and observed under fluorescence microscopy after treatment with PAM. (C and D) Imaging of shPRDX5-transfected A549 cells and Mock A549 cells exposed to PAM and stained with JC-1. The data are presented as the mean ± standard deviation of three independent experiments. Significant differences are indicated at *p < 0.05; **p < 0.01; ***p < 0.001 vs. the control. Con, control.
