Research Profile

My long-term research interests focus on understanding mechanisms of oncogenic transformation. We have recently studied the role of thymidylate synthase (TS) in tumorigenesis since TS plays a central role in DNA synthesis/repair and high levels of TS have correlated with a poor prognostic outcome in patients with lung, pancreas, colon, and rectal carcinomas. We demonstrated that ectopic expression of catalytically active human TS (hTS) was sufficient to induce a transformed phenotype in mammalian cells both in culture and in transgenic models confirming that it serves as a bona fide cancer therapeutic target. Our current work is focused on defining patterns of cooperation between TS and other cancer genes using a series of defined mouse models. Our goal is to use these transgenic animals to study the in vivo consequences of elevated TS on DNA stability, to test how this relates to tumorigenesis, and to improve the use of TS as a biomarker and therapeutic target.
