abstract：:DNA double-strand breaks (DSBs) can result in cell death or genetic alterations when cells are subjected to radiation, exposure to toxins, or other environmental stresses. A complex DNA-damage-response pathway is activated to repair the damage, and the inability to repair these breaks can lead to carcinogenesis. One o...
