Regulation of growth hormone secretion by growth hormone-releasing peptide-6 (GHRP-6)

Journal of Pediatric Endocrinology
Summary
Early clinical characterization of GHRP-6 as a potent growth hormone secretagogue in humans. Demonstrated that GHRP-6 stimulates GH release through a mechanism distinct from GHRH, and that combined administration produces synergistic GH responses.
Key Findings
- GHRP-6 potently stimulated GH release in human subjects
- Mechanism of action distinct from growth hormone-releasing hormone (GHRH)
- Synergistic GH response observed when GHRP-6 combined with GHRH

Use of growth hormone-releasing peptide 6 (GHRP-6) for the prevention of multiple organ failure
Cibrián D, Ajamieh H, Berlanga J, et al.
Clinical Science
Demonstrated that GHRP-6 administration prevented multiple organ failure in a liver ischemia-reperfusion injury model. The cytoprotective effects were mediated through anti-inflammatory and antioxidant mechanisms independent of growth hormone release.
- GHRP-6 prevented multiple organ failure following hepatic ischemia-reperfusion injury
- Cytoprotective effects were independent of GH secretion
