Mechanisms of Ovarian Carcinogenesis

Ovarian cancer is the eighth most common cancer in women and ranks first as the cause of death for gynecological cancers. Obviously, there is an urgent need to develop novel prevention and treatment methods for ovarian cancer. To do this, we must better understand key early events associated with ovarian cancer initiation and progression to identify important pathways that can ultimately be targeted with therapeutics.

The main focus of the laboratory is to understand the molecular and cellular basis of ovarian cancer initiation and progression. Specifically, we are interested in the role of cellular senescence, a state of irreversible cell growth arrest, in suppressor of epithelial ovarian cancer development. In addition, we are investigating how alterations in Wnt signaling pathway contribute to ovarian cancer development. The knowledge gained from these studies may ultimately lead to development of novel markers for ovarian cancer early detection and prognosis, and identification of novel therapeutic targets for ovarian cancer treatment.
