GnRH is a hormone that is produced in the hypothalamus region of the brain. Once produced, GnRH moves through the bloodstream to the pituitary gland. There, it binds to certain receptors, which signals the pituitary gland to create two more hormones: LH and follicle-stimulating hormone (FSH).
Growth-hormone-releasing hormone (GHRH), also known as growth-hormone-releasing factor (GRF, GHRF), as well as somatorelin (INN), somatoliberin, and somatocrinin, is a releasing hormone of growth hormone (GH).It is a 44 - amino acid peptide hormone produced in the arcuate nucleus of the hypothalamus.GHRH first appears in the human hypothalamus between 18 and 29 weeks of gestation, which corresponds to the start of production of growth hormone and other somatotropes in fetuses.ain article: Growth hormone-releasing hormone receptor. The GHRHR is a member of the secretin family of G protein-coupled receptors, and is located on chromosome 7. This protein is transmembranous with seven folds, and its molecular weight is approximately 44 kD.
