PM2.5 induces DNA and mitochondria damage in HK-2 cells. a Nuclear changes of HK-2 cells were detected following staining with a DNA-binding fluorochrome, Hoechst 33342. The apoptotic bodies or chromatin condensation was marked with red arrows. b Ultrastructural analysis in PM2.5 (400 μg/mL)-treated HK-2 cells. Black arrows indicate mitochondria. c JC-1 red/green fluorescence intensity ratio was used to express the changes of MMP. Decreased ratio indicated a decrease in MMP
