WebConsidering that the action of gonadotropin-releasing hormone (GnRH) may be mediated via different signaling pathways in extrapituitary tissues, in the present study we investigated the role of the human GnRH receptor (GnRHR) in activating mitogen-activated protein kinases (MAPKs), which regulate cell growth, division, and differentiation. WebThe hypothalamic GnRH (Gonadotropin Releasing Hormone) plays a key role in coordinating the levels of hormones in the hypothalamic-pituitary-gonadal axis. Thus, GnRH plays a decisive role in the neuroendocrine regulation of human reproduction. GnRH acts via a specific GPCR: GnRHR and triggers the synthesis of the common α- and β-chains of …
