Scholarly Interests

The myometrium plays a fundamental role in a variety of female reproductive events and has a significant impact on pregnancy outcome. The structural and functional abnormalities of myometrium can lead to reproductive disorders, such as implantation failure, preterm labor, and uterine rupture, some of which are severe causes of neonatal mortality and morbidity. Despite the long-recognized importance of myometrial function in pregnancy, key signaling pathways that control myometrial development and function are not well defined. Current studies in my laboratory are to identify the role of TGFß signaling and micro-RNA in myometrial contractility and pregnancy, and define the mechanistic contributions of dysregulated TGFß signaling to the development of myometrial defects. Results of these studies will guide the design of novel therapies for myometrial dysfunction and myometrium-associated diseases. Research in this area is supported by NIH grant. My lab is also interested in understanding the SMAD signaling pathway in ovarian follicular development and ovulation. SMAD proteins can be classified into receptor-regulated SMADs (Smad1, 2, 3, 5, 8), the common SMAD (Smad4), and inhibitory SMADs (Smad6, 7). Our previous studies have identified a key role of SMAD2/3 in the maintenance of female fertility and follicular cell function. Ongoing studies in my laboratory focus on defining the ovarian function of inhibitory Smad (i.e., Smads 6 and 7) signaling and the interrelationship between inhibitory Smad signaling and Smad2/3 and/or Smad1/5/8-mediated signaling in the ovary. The third area we are interested in is to develop novel approaches to treat infertility as well as safe contraceptives for contraception. We are currently seeking highly motivated Ph.D. Candidates.
