Preferred Label : Gonadotropin-Releasing Hormone Signaling Pathway;
NCIt related terms : GnRH signaling pathway;
Alternative definition : KEGG: Gonadotropin-releasing hormone (GnRH) secretion from the hypothalamus acts upon
its receptor in the anterior pituitary to regulate the production and release of the
gonadotropins, LH and FSH. The GnRHR is coupled to Gq/11 proteins to activate phospholipase
C which transmits its signal to diacylglycerol (DAG) and inositol 1,4,5-trisphosphate
(IP3). DAG activates the intracellular protein kinase C (PKC) pathway and IP3 stimulates
release of intracellular calcium. In addition to the classical Gq/11, coupling of
Gs is occasionally observed in a cell-specific fashion. Signaling downstream of protein
kinase C (PKC) leads to transactivation of the epidermal growth factor (EGF) receptor
and activation of mitogen-activated protein kinases (MAPKs), including extracellular-signal-regulated
kinase (ERK), Jun N-terminal kinase (JNK) and p38 MAPK. Active MAPKs translocate to
the nucleus, resulting in activation of transcription factors and rapid induction
of early genes.;
