Overview

Gonadotropin-releasing hormone (GnRH) is a key regulator of mammalian reproduction. After its release from the hypothalamus, this decapeptide hormone is transported from the brain via the portal blood circulation to the anterior pituitary gland, where it stimulates the synthesis and release of the gonadotropins that play pivotal roles in the regulation of the gonads (i.e. ovary and testis). In addition, GnRH has been implicated as an autocrine regulator in several extra-pituitary tissues, including the ovary and placenta, but the specific functions are still unknown. Numerous synthetic analogs of GnRH are now being used in different areas of reproductive medicine, such as assisted reproduction. The long-term goal of my research program is to understand the multi-faceted role of GnRH in reproductive health and medicine.

Research

Normal and neoplastic ovarian surface epithelium -endocrine and hereditary influences
The epithelial ovarian carcinomas, which comprise over 85% of human ovarian cancers, arise in the ovarian surface epithelium (OSE). The etiology and early events in the progression of these carcinomas are among the least understood of all major human malignancies because there are no appropriate animal models, and because methods to culture OSE have become available only recently. The purpose of this project is to define the molecular mechanisms which underlie the control of normal and neoplastic OSE cell growth, differentiation and expression of indicators of neoplastic progression, by GnRH and other key reproductive hormones. Also, the hormonal response of OSE isolated from overtly normal ovaries of women with and without family histories of ovarian cancer will be examined, in order to define the specific abnormalities in the OSE that lead to a high risk of developing ovarian cancer. The results of this research will be relevant to the development of more efficient chemotherapeutic methods for ovarian cancer treatment.

Function of GnRH in endometrium and placenta
The establishment of a successful pregnancy is dependent on the coordinated development of the implanting embryo and the lining of the uterus (endometrium). To date, the regulatory factors involved in the development of a uterine environment that promotes embryonic implantation and/or the formation of functional placenta remain poorly characterized. In this project, the regulation of GnRH in endometrial and trophoblast cells undergoing differentiation in culture will be examined. A better understanding of the role of GnRH and related hormones in implantation and placentation is likely to reduce the number of couples assigned the frustrating and costly diagnosis of unexplained infertility.

Endocrine control of reproduction
The aim of this project is to better understand the hormonal control of reproductive function by GnRH. Experiments are designed to test the hypothesis that, in addition to its well-known role in the regulation of pituitary hormone secretion, GnRH is also an autocrine regulator of ovarian hormone production. Further experiments are proposed to examine the regulation of the human GnRH receptor, at the level of gene transcription. It is expected that this research will lead to a better understanding on the cellular and molecular basis underlying the use of GnRH analogs in many different areas of reproductive medicine, such as fertility and sterility, control of ovulation and assisted reproductive technology.
