PQ reduces cell viability and induces apoptosis of mouse AT-II cells (A) Mouse AT-II cells were treated with PQ (200, 400, 800, 1600 μM) for 24 h. The values are given as the means ± SD from 4 independent experiments. The IC50 value of PQ against AT-II cells was 675μM. ** P < 0.01 vs control group. (B) Mouse AT-II cells were treated with 600 μM PQ for 24 h. The apoptosis of the cells was detected by using a FACSalibur flow cytometer. The values are given as the means ± SD from 4 independent experiments. ** P < 0.01 vs control group. (C) Mouse AT-II cells were treated with 600 μM PQ for 24 h and then stained with Hoechst 33342. The cells were detected by a fluorescence microscope (Scale bar: 100 μm).
