Targeting ATM enhances radiation sensitivity of colorectal cancer by potentiating radiation-induced cell death and antitumor immunity.

Introduction: The efficacy of radiotherapy in colorectal cancer (CRC) is often limited by radiation resistance. Ataxia telangiectasia mutated (ATM) is well known for its role in repairing double-strand DNA breaks within the DNA damage response (DDR) pathway. However, whether ATM mediates other mechanisms contributing to radiation resistance remains insufficiently investigated.

Risk factors associated with short-term mortality in patients with candidemia and the predictive value of serum cytokine level.
