Abstract

The response of cancer cells to treatment with anticancer agents is mediated in part by proteins controlling both the cell cycle progression and the genomic integrity, including p53, p73 and checkpoint proteins chk1 and chk2. We here summarized the cellular functions of these proteins, their alterations in human tumors and the impact of their mutations/alterations on cellular response to treatment, Particular attention has been paid for those studies performed in isogenic cell systems, to minimize as much as possible interference by other alterations invariably present when different cell types are considered. Focus has also be given to the approaches taken to exploit the differential expression of these proteins between normal and tumor cells to improve the selectivity of treatment with anticancer agents.
