Physiology of Gonadotropin-Releasing Hormone (GnRH): Beyond the Control of Reproductive Functions
GnRH is the hypothalamic main regulator of the hypothalamic-pituitary-gonadal reproductive axis, but it was found to exert additional functions due to the wide distribution of its receptors both in central nervous system (from cortex to spinal cord) and in peripheral organs and tissues. The possible activity of GnRH/GnRHR system at the level of the hippocampus has raised the interest on the eff...
متن کاملGonadotropin-Releasing Hormone (GnRH) Receptor Structure and GnRH Binding
Gonadotropin-releasing hormone (GnRH) regulates reproduction. The human GnRH receptor lacks a cytoplasmic carboxy-terminal tail but has amino acid sequence motifs characteristic of rhodopsin-like, class A, G protein-coupled receptors (GPCRs). This review will consider how recent descriptions of X-ray crystallographic structures of GPCRs in inactive and active conformations may contribute to und...
متن کاملRole of gonadotropin-releasing hormone (GnRH) in ovarian cancer
The expression of GnRH (GnRH-I, LHRH) and its receptor as a part of an autocrine regulatory system of cell proliferation has been demonstrated in a number of human malignant tumors, including cancers of the ovary. The proliferation of human ovarian cancer cell lines is time- and dose-dependently reduced by GnRH and its superagonistic analogs. The classical GnRH receptor signal-transduction mech...
متن کاملHypothalamic gonadotropin-releasing hormone (GnRH) receptor neurons fire in synchrony with the female reproductive cycle.
Gonadotropin-releasing hormone (GnRH) controls mammalian reproduction via the hypothalamic-pituitary-gonadal (hpg) axis, acting on gonadotrope cells in the pituitary gland that express the GnRH receptor (GnRHR). Cells expressing the GnRHR have also been identified in the brain. However, the mechanism by which GnRH acts on these potential target cells remains poorly understood due to the difficu...
متن کاملPolygenic expression of gonadotropin-releasing hormone (GnRH) in human?
A non-mammalian lamprey-like gonadotropin-releasing hormone (lGnRH) has been detected in human hypothalami using a combination of immunocytochemistry, high performance liquid chromatography and radioimmunoassay. The hypothalamic distribution of immunopositive lGnRH neurons is similar to that observed for those containing the mammalian gonadotropin-releasing hormone (mGnRH), indicating a possibl...
