The role of the ataxia telangiectasia mutated gene in lung cancer: recent advances in research.

ABSTRACT: Lung cancer is the leading cause of death due to cancer worldwide. It is estimated that approximately 1.2 million new cases of lung cancer are diagnosed each year. Early detection and treatment are crucial for improvements in both prognosis and quality of life of lung cancer patients. The ataxia telangiectasia mutated (ATM) gene is a cancer-susceptibility gene that encodes a key apical kinase in the DNA damage response pathway. It has recently been shown to play an important role in the development of lung cancer. The main functions of the ATM gene and protein includes participation in cell cycle regulation, and identification and repair of DNA damage. ATM gene mutation can lead to multiple system dysfunctions as well as a concomitant increase in tumor tendency. In recent years, many studies have indicated that single nucleotide polymorphism of the ATM gene is associated with increased incidence of lung cancer. At the same time, the ATM gene and its encoding product ATM protein predicts the response to radiotherapy, chemotherapy, and prognosis of lung cancer, thus suggesting that the ATM gene may be a new potential target for the diagnosis and treatment of lung cancer.
