Murine tumor suppressor models.
Tumor suppressor genes have been shown to be necessary for proper maintenance of cell growth control. Inactivation of these genes in the germline of humans is linked to inherited cancer predisposition. Moreover, sporadically arising human tumors often have somatic mutations in tumor suppressor genes. During the past few years, advances in molecular and cellular biology have led to the creation of animal models that have germline mutations of various tumor suppressor genes. Such mice potentially represent important animal models for familial cancer predisposition syndromes, and the study of the tumorigenesis process has been greatly assisted by their development. Such models have also demonstrated the importance of tumor suppressor function in embryonic development. In this review, we describe mice with inactivated germline tumor suppressor genes that are genetically analogous to 10 different inherited cancer syndromes in humans. We describe the variable usefulness of the mutant mice as models for human disease.
