Role of nerve growth factor and FSH receptor in epithelial ovarian cancer.
The neurotrophins (NT) including nerve growth factor (NGF) are a family of related growth factors that are of major importance in the regulation of neuronal survival and differentiation. In the ovary, they can help in follicular maturation and ovulation by inducing the FSH receptor (FSHR). Current literature shows that perimenopausal ovarian surface epithelium (OSE) can also express FSHR. By G protein link, this FSHR is capable of precipitating neoplasia of OSE, which is the commonest in the ovary. NT are implicated as the cause of this aberrant expression of FSHR in OSE. By central action NT can lower serum FSH, as is found in ovarian cancer. Thus, NGF deregulates expression of FSHR in OSE and secretion of FSH from the pituitary. This phenomenon may hold the key to the hitherto unexplained carcinogenic process of sporadic epithelial ovarian cancer.
