The mTOR pathway: Implications for DNA replication

DNA replication plays a central role in genome health. Deleterious alteration of replication dynamics, or “replication stress”, is a key driver of genome instability and oncogenesis. The replication stress response is regulated by the ATR kinase, which functions to mitigate replication abnormalities through coordinated efforts that arrest the cell cycle and repair damaged replication forks. mTOR kinase regulates signaling networks that control...
