p53 loss of function: implications for the processes of immortalization and tumorigenesis.

Abstract excerpt

The complex process of cell immortalization and transformation is likely to involve the inactivation of growth regulatory genes. Mutations (deletions, missense mutations) in the p53 gene are the most frequently observed genetic alteration in human tumors, making p53 a candidate for a cellular protein involved in the control of cell growth. Two recent studies have examined the role of p53 in immortalization and...
