MECHANISMS OF CELL-CYCLE CHECKPOINTS: AT THE CROSSROADS OF CARCINOGENESIS AND DRUG DISCOVERY*
1 Jan 2000
Abstract excerpt
Human tumors arise from multiple genetic changes that gradually transform growth-limited cells into highly invasive cells that are unresponsive to growth controls. The genetic evolution of normal cells into cancer cells is largely determined by the fidelity of DNA replication, repair, and division. Cell-cycle arrest in response to stress is integral to the maintenance of genomic integrity. The control mechanisms...
