My research focuses on the mechanisms of embryo implantation and placentation (development of a functional placenta), in particular, the influence exerted by the uterus. The endometrium or lining of the uterus is hostile to the implantation of an embryo except during a few days in each menstrual cycle. Using state-of-the-art technology, we have identified a number of molecules that are highly regulated at the time of uterine receptivity, embryo implantation and placentation. These molecules include a number of proteases such the proprotein convertase family and the HtrA family proteases. In particular, we identified and cloned the third member of the HtrA family, HtrA3. We are interested in both understanding the functions of these proteases at the molecular level and exploring the potentials of these molecules to be targets for treating infertility and for the development of post-coital contraception.
