Explanation GHRH 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 is released from neurosecretory nerve terminals of these arcuate neurons, and is carried by the hypothalamo-hypophyseal portal system to the anterior pituitary gland, where it stimulates growth hormone (GH) secretion by stimulating the growth hormone-releasing hormone receptor. GHRH is released in a pulsatile manner, stimulating similar pulsatile release of GH.

Reference
  • Growth hormone (GH) secretion declines with aging, and parallels between normal aging and the signs and symptoms of adult GH deficiency have led to interest in the potential utility of replacing or stimulating GH to promote physical and psychological function and to prolong the capacity for independent living in older adults. The aging pituitary remains responsive to GH-releasing hormone (GHRH) and to ghrelin-mimetic GH secretagogues (GHS), and these agents have both theoretical and practical potential advantages as alternatives to the use of GH itself in this setting. Studies of the long duration and large scale needed to test the efficacy of GHRH or GHS on clinically important endpoints cannot be designed or conducted without first obtaining promising results in studies of smaller size focused on manageable intermediate endpoints, and all studies published to date have been of this latter type. GHRH and GHS both stimulate GH secretion, and, when given repeatedly, elevate IGF-I levels to within younger adult normal ranges. When GHRH treatment is continued for several months, these hormonal changes yield an increase in lean body (muscle) mass. GHRH, like GH, reduces body fat, but similar effects have not yet been shown with GHS. GHRH treatment has not yielded consistent improvements in physical function, although it may have a stabilizing effect. Chronic treatment with a short-acting GHRH did not improve sleep, possibly due to lack of sustained activity throughout the night. Compared to placebo, GHRH treatment improved certain tests of cognitive performance. These results, while encouraging, do not yet support the routine use of GHRH or GHS in normal aging.

  • Growth hormone (GH)-releasing hormone (GHRH) is produced by the hypothalamus and stimulates GH synthesis and release in the anterior pituitary gland. In addition to its endocrine role, GHRH exerts a wide range of extrapituitary effects which include stimulation of cell proliferation, survival and differentiation, and inhibition of apoptosis. Accordingly, expression of GHRH, as well as the receptor GHRH-R and its splice variants, has been demonstrated in different peripheral tissues and cell types. Among the direct peripheral activities, GHRH regulates pancreatic islet and β-cell survival and function and endometrial cell proliferation, promotes cardioprotection and wound healing, influences the immune and reproductive systems, reduces inflammation, indirectly increases lifespan and adiposity and acts on skeletal muscle cells to inhibit cell death and atrophy. Therefore, it is becoming increasingly clear that GHRH exerts important extrapituitary functions, suggesting potential therapeutic use of the peptide and its analogs in a wide range of medical settings.
