Figure 3. — Apoptosis induced by X-irradiation in DNA-PKcs knockdown and control cells. Cells were irradiated with 4 Gy X-ray. Apoptosis was assessed 48 hours after radiation treatment. A, Representative images of sub-G1 population in different cell lines 48 hours after 4 Gy irradiation. B, Representative images of annexin V/PI double staining in different cell lines 48 hours after 4 Gy irradiation. DNA-PKcs indicates DNA-dependent catalytic subunit of protein kinase; PI, propidium iodide.
