Research Interests:

Inherited predisposition to human cancer can occur by one of two genetic mechanisms. The first is by the inheritance or acquisition of a germline mutation in one of the genes involved in the pathway to malignant transformation of a particular cell type. The second is by the inheritance or acquisition of a germline mutation in a gene that controls the ability of a cell to replicate or repair its DNA and whose disruption consequently is associated with an increased mutation frequency throughout the genome. The disruption of such genes can be recognized clinically by an increased incidence of a particular tumor type in affected individuals or by an increased incidence of many tumor types in affected individuals. The study of these individuals and their families has been instrumental in the identification of important genes that control cell growth directly or that function to maintain genomic stability. Two examples of such genes are APC and BLM, mutations in which lead to adenomatous polyposis coli and Bloom's syndrome, respectively, and which encode a tumor suppressor and a RecQ-like helicase. Characteristics of each gene and their protein products are being studied in the laboratory in order to determine their normal functions and how their disruption leads to the development of cancer. Finally, mouse models of human cancers are being developed, using genetic alteration of both Apc and Blm, in order to study the formation of intestinal, lung, mammary and pancreatic tumors.
