Uterine fibroids are the most common tumors of the female reproductive tract, clinically relevant in 20-40% of reproductive aged women, occurring in up to 70% of white and 80% of black women by the age of 50 years. Uterine fibroids account for over 200,000 hysterectomies annually in the United States alone. Currently there is no approved drug for the long-term medical therapy of fibroids. One of our research interests is to understand the biology of an aberrantly expressed G protein-coupled receptor that contributes to the fibroids tumor growth. We utilize genetically modified animal models as well as primary human fibroids cells to study the etiology of uterine leiomyomas. Our goal is to develop small molecule and peptidomimetic drugs for the treatment of uterine fibroids.
My laboratory also studies the biology of a sperm-specific sodium-proton exchanger that regulates intracellular pH and motility of the sperm. In addition we are interested in novel cancer testis antigens and development of targeted cancer therapies.
