Activation of apoptosis pathway induced by PM2.5 in HK-2 cells. a Cells were treated with the indicated concentrations of PM2.5 for 24 h (left) or PM2.5 (200 μg/mL) at different time intervals (right) to examine the total protein expression of apoptosis-related proteins. b Intensity of protein bands was quantified using ImageJ software and normalized to β-actin. Data are expressed as mean ± SD from three independent experiments. *p < 0.05 and **p < 0.01, compared with control group
