Brief description The steroid hormone estrogen plays a critical role in the development of human breast cancer. Anti-estrogen therapy has been believed to be an effective treatment of breast cancer over more than 100 years. However, the anti-estrogen therapy is still restricted mainly because of that estrogen has fundamental physiological actions and a wide range of beneficial effects on bone, brain, cardiovascular and other targeted tissues. Thus, it has become a primary focus of inquiry to understand how estrogen specifically functions in breast cancer but not in normal tissues. Estrogen serves different functions involving a series of biochemical reactions called signal transduction pathways that can couple estrogen to a specific function, such as cancer formation. We have recently found that a enzyme named sphingosine kinase (SK) activation triggers a novel signal transduction pathway in regulation of cell growth and tumour formation, and that this pathway was activated by estrogen in human breast cancer cells. Thus, we seek to identify how estrogen activate SK and how they contribute to the development of breast cancer. It will ultimately provide a potential target for therapeutic intervention and may yield new compounds that have clinical benefit for anti-breast-cancer.
