title: A paradigm for cancer treatment using the retinoblastoma gene in a mouse model.
abstract: Discovery of tumor suppressor genes has provided a rational approach to cancer prevention and treatment. Loss of retinoblastoma susceptibility gene (Rb) function is a rate-limiting event in the development of human and mouse cancers. Establishment of animal models of cancer associated with Rb deficiency allowed us to develop and test long-awaited approaches to genetic correction for treating tumors in vivo. Recent studies demonstrated that (1) prevention of carcinogenesis is achieved by correction of gene copy number in Rb+/- mice, and (2) reconstitution of Rb gene functions is sufficient for suppression of neoplasia in immunocompetent mice. These results fulfill a promise of cancer treatment by reconstitution of tumor suppressor function.
