Luteinizing Hormone Releasing Hormone (LH-RH), salmon is the hypophysiotropic decapeptide synthesized in the hypothalamus that plays a crucial role in the control of reproductive functions.
Luteinizing hormone-releasing hormone (LHRH) is the key hormone in the control of reproductive functions.LHRH acts as an antimitogenic factor through the activation of the Gi-cAMP intracellular signaling pathway. LHRH might act as an inhibitory factor on both cell proliferation and metastatic behavior in melanoma cells[1]. The hypothalamic decapeptide luteinizing hormone-releasing hormone (LHRH) plays a central role in the control of reproduction by stimulating the release of pituitary luteinizing hormone (LH) and follicle-stimulating hormone (FSH), which in turn promote gonadal functions and regulate sex steroid secretion. The effects of LHRH are mediated by high-affinity G protein-coupled LHRH-receptor (LHRH-R) on pituitary gonadotropes. The responses to LHRH vary under different conditions and critically depend on the regimens of administration and doses delivered to gonadotrope cells[2].
