Biography

Cecily Bishop, Ph.D., is an Adjunct Research Assistant Professor in the Division of Reproductive & Developmental Sciences at ONPRC.  Her research aims to investigate the incompletely understood molecular pathways associated with normal and pathologic ovarian and uterine angiogenesis.

The mid-cycle surge of luteinizing hormone (LH) is responsible for reorganizing the ovulatory follicle into a corpus luteum (CL), which produces the progesterone necessary for implantation of the embryo. As part of the structural and cellular changes that happen after ovulation, a wave of neovascularization occurs resulting in the formation of a CL with a network of highly permeable capillaries. In turn, this newly formed vasculature allows for the significant levels of progesterone produced by the CL to enter the circulation and support implantation/ pregnancy. Assisted reproduction protocols used to treat infertility in women often lead to the development of ovaries with many CL. In women and old world primates, development of multiple CL following ovarian stimulation result in abnormal ovarian/luteal vascularization and ovarian hyperpermeability that, in turn, may lead to abdominal ascites and systemic vascular dysfunction (known as ovarian hyperstimulation syndrome, or OHSS). Dr. Bishop’s research aims to identify novel targets for preventing OHSS from occurring in women undergoing infertility treatments.

Techniques used to interrogate mediators of ovarian and uterine angiogenesis range from molecular (i.e. gene expression and shRNA-knockdown of select gene targets), to contrast-enhanced ultrasound (CEUS) and dynamic contrast enhanced magnetic resonance imaging (DCE-MRI) of reproductive tissue blood flow, volume, and permeability.

Dr. Bishop is also involved in use of CEUS and 3D/4D ultrasound technology to assist studies of other novel genes involved in folliculogenesis, evaluate ovarian tissue engraftment following cryopreservation, and the role of the steroid hormone progesterone in normal ovarian function using shRNA-knockdown of specific progesterone receptors during luteal formation. Finally, she is also part of studies into the role of androgens and diet in a nonhuman primate model of polycystic ovarian syndrome (PCOS) funded by a NICHD National Center for Translational Research in Reproduction and Infertility (NCTRI) grant.
