ATM is the most significant molecule involved in monitoring the genomic integrity of the cell. Any damage done to DNA relentlessly
challenges the cellular machinery involved in recognition, processing and repair of these insults. ATM kinase is activated
early to detect and signal lesions in DNA, arrest the cell cycle, establish DNA repair signaling and faithfully restore the
damaged chromatin. ATM activation plays an important role as a barrier to tumorigenesis, metabolic syndrome and neurodegeneration.
Therefore, studies of ATM-dependent DNA damage signaling pathways hold promise for treatment of a variety of debilitating
diseases through the development of new therapeutics capable of modulating cellular responses to stress. In this review, we
have tried to untangle the complex web of ATM signaling pathways with the purpose of pinpointing multiple roles of ATM underlying
the complex phenotypes observed in AT patients. 相似文献
