Uterine endometrial cancer incidence (~65,950 new cases/year) and deaths (~12,550 deaths/year) are on the rise. To help endometrial cancer patients and cure endometrial cancer, we need understand the characteristics of this disease. The current focus of our work is to understand molecular mechanisms of endometrial tumor progression and utilize target therapy or molecular enhanced hormonal therapy to treat endometrial cancer and other hormone-driven cancers.
