Effects of CQ and zinc on the DNA damage dynamics of HeLa cells. a and b: Cells were treated with 5 μM CQ and 10 μM zinc in the presence or absence of 4 Gy of irradiation for 0.5–24 h. The cells were stained with propidium iodide (PI) for 10 min and were examined under a confocal microscope. c: Cell lysates were prepared, loaded onto 12% SDS PAGE gels (40 μg per well), and blotted with antibodies against γ-H2AX and β-actin. Shown are representative images of two independent experiments
