Description
Growth hormone releasing hexapeptide (GHRP-6) is a synthetic met-enkephalin analog that induces the release of growth hormone in vivo through binding of the ghrelin receptor. GHRP-6 increases proliferation in astrocytes through a mechanism that involves PI3K/Akt signaling. GHRP-6 also inhibits development of restraint stress-induced gastric lesions and reverses ovariectomy-induced effects on serum glucose and insulin levels. Additionally, GHRP-6 decreases locomotor activity and increases food intake in vivo.
