There is an urgent need in oncology to link molecular aberrations in tumors with therapeutics that can be administered in a personalized fashion. One approach identifies synthetic-lethal genetic interactions or emergent dependencies that cancer cells acquire in the presence of specific mutations. Using breast epithelial cells as a base we have developed methodologies to connect tumor mutations with drug sensitivity using quantitative functional genomic screens to create chemical-genetic interaction maps. The focus of the lab is to use these maps to uncover new synthetic-lethal relationships and identify new biomarkers for targeted as well as chemotherapy. I will describe new approaches to use these quantitative maps to uncover drug mechanism of action as well as integrate with cancer cell line collections to predict drug responses in cancer.
