Ionizing Radiation-Induced DNA Damage, Response, and Repair

Significance: Ionizing radiation (IR) is an effective and commonly employed treatment in the management of more than half of human malignancies. Because IR's ability to control tumors mainly relies on DNA damage, the cell's DNA damage response and repair (DRR) processes may hold the key to determining tumor responses. IR-induced DNA damage activates a number of DRR signaling cascades that control cell cycle arrest, DNA repair, and the cell's...
