Research Summary

My laboratory’s focus is hereditary cancer predisposition. One project in the laboratory arose from studies of the nevoid basal cell carcinoma syndrome (NBCCS), a human genetic disease characterized by skin cancer and brain tumors as well as a variety of birth defects. We isolated the NBCCS gene and showed that it is homologous to Drosophila "patched," a key gene in Drosophila embryonic development. We are now examining human homologs of other members of the patched pathway and investigating their roles in human cancer. In addition, we have become involved in large molecular epidemiology studies, using high throughput sequencing to search in an unbiased way for novel skin cancer genes and the interaction between genes and environment in cancer causation.

Extensive Research Description

Genes involved in carcinogenesis often play a critical role in embryonic development and cellular differentiation. My laboratory focuses on analyzing the normal function of these genes and the mechanisms by which mutations lead to cancer. One emphasis of the laboratory is the gene underlying the nevoid basal cell carcinoma syndrome (NBCCS), an autosomal dominant disorder characterized by skin cancer, ovarian tumors, and brain tumors as well as developmental defects of the brain, bones, and teeth. We isolated the NBCCS gene by positional cloning and showed that it is homologous to Drosophila "patched". The Drosophila version of this gene encodes a cell surface protein that plays a role in segment polarity; i.e., distinguishing anterior from posterior in the developing fly. We are examining other segment polarity genes in human cancer. Other disease genes under study include MEN1 (multiple endocrine neoplasia type 1) and BRCA1 (the main gene responsible for hereditary breast cancer).

A second area of interest is the application of new molecular techniques, such as high throughput sequencing, to clinical diagnosis of cancer predispostion syndromes. Through collaboration with other investigators in the Department of Genetics and elsewhere in the medical school, we carry the most recent discoveries about genetic disorders and novel methodology from the research laboratory to the medical setting.
