Knockdown of NFBD1 expression affects radiosensitivity. (a and b) Cells were plated at low density, irradiated and colonies counted after 14 days. Results are normalized for effects of NFBD1 and fitted to a standard linear quadratic model. (c) The percentage of apoptotic cells (early apoptosis+late apoptosis) was measured using Annexin V and propidium iodide with flow cytometry. *P<0.05, **P<0.01 and ***P<0.001
