DNA-dependent protein kinase inhibitor induces apoptosis in colon cancer cells

Among all types of DNA damage, DNA double-strand breaks (DSBs) are considered the most deleterious form induced by either endogenous factors (oxi-dative damages, mismatches, altered chromatin structures, and missing, or modified nucleotides) or exogenous factors, i.e., ultraviolet (UV) radiation, ionizing radiation (IR), and chemicals or drugs. This study aimed: To evaluate the effect of DNAPKi NU7441 on the HCT116 cell line.
