Gonadotropin-releasing hormone/gonadotropin-releasing hormone receptor signaling in the placenta

Current Opinion in Endocrinology, Diabetes & Obesity, 2011
This review summarizes our current understanding of the role of gonadotropin-releasing hormone (GnRH)/GnRH receptor (GnRHR) signaling at the maternal-fetal interface.Several isoforms of GnRH and GnRHR are described. The hypothalamic decapeptide, GnRH-I, binds to the anterior pituitary and induces the synthesis and secretion of luteinizing hormone and ...

Evolution of gonadotropin-releasing hormones

Trends in Endocrinology & Metabolism, 1992
GnRH was originally isolated as a hypothalamic peptide hormone that regulates the reproductive system by stimulating the release of gonadotropins from the anterior pituitary. However, multiple molecular forms of the peptide have evolved, which have been coopted for a variety of regulatory functions: as a neurotransmitter in the central and sympathetic ...

Conformation of gonadotropin releasing hormone

Biochemistry, 1976
The conformation of the gonadotropin releasing hormone (Gn-RH), whose primary sequence is pGlu-His-Trp-Ser-Tyr-Gly-Leu-Arg-Pro-GlyNH2, and of several of its structural analogues has been studied by circular dichroism, optical rotatory dispersion, and fluorescence spectroscopy.

Clinical applications of gonadotropin-releasing hormone and gonadotropin-releasing hormone analogs.

Fertility and sterility, 1983
Investigations have proved the clinical importance of hypothalmic gonadotropin-releasing hormone (GnRH) and its agonistic and antagonistic analogs. A pulsatile pattern of stimulation of specific receptors in the anterior pituitary gonadotrope has been shown to activate pituitary-gonadal function; continuous administration inhibits it.

Gonadotropin-Releasing Hormone

Annual Review of Medicine, 1975
The existence of a hypothalamic gonadotropin-releasing hormone long suspected from indirect evidence (1) has now been conclusively proven. In 1971, the primary structure of porcine (2) and subsequently ovine (3) luteinizing hormone-releasing hormone or factor (LRH or LRF) was determined to be the decapeptide pGlu-HisĀ­ Trp-Ser-Tyr-Gly-Leu-Arg-pro-Gly ...
