Mar 5, 2021 Hexarelin is classified as a synthetic growth hormone-releasing peptide (GHRP) that has been widely studied within the context of cardioprotection and cell function. This peptide has been employed in laboratory conditions to elucidate the action of ghrelin, a hormone which requires acylation to bind to GHS-R1a and consists of 28 amino acids. Hexarelin gets part of its name from hexapeptide, as the peptide is made of 6 amino acids. The other part of its name is derived from the synthetic analog of ghrelin. Hexa(six) and (gh)relin, hexarelin. Autophagy management is considered a contributor to cardioprotection. One study investigated the function of potential governing mechanisms and autophagy and suggested that heart muscle cells’ hypertrophy, cell death, and oxidative stress were reportedly inhibited by Hexarelin exposure. Hexarelin peptide appeared to manage the upward autophagy signaling by slowing the mTOR phosphorylation. Researchers of this study proposed that Hexarelin may reduce hypertrophy of heart muscle cells and cell death. Hexarelin is researched primarily within the context of the pituitary gland, and studies have suggested it may also induce additional endogenous production of growth hormone. Similar to its growth hormone-releasing peptide counterparts, it may potentially act to inhibit somatostatin functions while elevating growth hormone levels through magnifying the GHRH signal transduction pathway.
