Growth hormone secretion

“Growth hormone secretion” refers to the physiological process by which growth hormone (GH) is released from the anterior pituitary gland, regulated by stimulatory (growth hormone-releasing hormone, ghrelin) and inhibitory (somatostatin) signals from the hypothalamus, as well as feedback from peripheral hormones like insulin-like growth factor 1 (IGF-1)[1][2][3][4][5][6]. It is not a discrete molecule, gene, protein, or receptor, but rather a complex process mediated primarily through the growth hormone-releasing hormone receptor (a G protein-coupled receptor, GHRHR), growth hormone receptor (type I cytokine receptor, GHR), and somatostatin receptors (GPCRs)[1][4][6]. Disruption in the secretion process can result in conditions like growth hormone deficiency or excess (acromegaly, gigantism)[2][3][6]. Therapeutic targeting in this context means modulating relevant hormones or their receptors, not targeting "growth hormone secretion" as a singular molecular entity.
