Our previous studies in ovariectomized ewes have provided direct evidence that FSH secretion is comprised of basal and episodic modes. In those studies, each GnRH pulse coincided with an FSH pulse, but additional FSH pulses were noted. To determine w

Four different GnRHs and one GnRH receptor are reported to be expressed in various mammals, whereas 13 GnRHs and numerous GnRH receptors have been identified in various nonmammalian vertebrates. The nucleotide sequencing of the human genome provided

Mammalian gonadotropin-releasing hormone (GnRH I) is a hypothalamic decapeptide that governs gonadotropin secretion through interaction with its seven transmembrane (7TM), G protein-coupled receptor (GPCR) expressed by anterior pituitary cells. A sec

Mammalian gonadotropin-releasing hormone (GnRH I) is a hypothalamic decapeptide that stimulates gonadotropic hormone secretion upon interaction with its membrane receptors (type I) on pituitary cells, thereby governing reproductive processes. A secon

The level of LH secretion is determined by both alterations in gonadotrope responsiveness and alterations in GnRH secretion. The molecular mechanisms underlying gonadotrope responsiveness are unknown, but may include G protein-coupled receptor kinase

The mechanisms of GnRH-induced desensitization of LH secretion are poorly understood. Protein kinase C (PKC) and protein kinase A (PKA) desensitize some receptors of the 7-membrane type, and the GnRH receptor has consensus phosphorylation sites for P

The molecular cloning and nucleotide sequencing of the gonadotropin-releasing hormone (GnRH) receptor represented an enhanced step in the experimental effort to understand this key molecule in the reproductive process at a cell and molecular level. A

Inhibition of the growth of hormone related human tumor cells in vitro by GnRH agonists and antagonists suggests a direct effect on cell growth and proliferation, and this effect may be achieved through its receptors present in tumor cells. However,

Secretogranin II (SgII) is an acidic 86-kD protein which is synthesized by most neuroendocrine cells but occurs in greatest abundance in the anterior pituitary gland where it is localized primarily in gonadotrophs. In the present studies, we investig
