Effects of CQ and zinc on the apoptosis of HeLa cells. a and b: Cells were treated with 5 μM CQ and 10 μM zinc for 4 h prior to treatment with 6 Gy of irradiation. Apoptosis was measured using propidium iodide (PI)/annexin V double staining in HeLa cells. Representative images of three independent experiments are shown. *P < 0.05
