Summary

Growth-hormone-releasing hormone (GHRH) stimulates growth hormone (GH) release. GHRH is crucial for diagnosing GH deficiency and shows promise in treating GH-deficient children by promoting natural GH secretion.

Area of Science:

  • Endocrinology
  • Neuroendocrinology
  • Molecular Endocrinology

Background:

  • Growth-hormone-releasing hormone (GHRH) is a hypothalamic peptide hormone.
  • It specifically stimulates the synthesis and release of growth hormone (GH) from anterior pituitary somatotrope cells.
  • GHRH is the final hypothalamic hormone to be characterized, synthesized, and clinically applied.

Purpose of the Study:

  • To review the discovery and characterization of GHRH.
  • To elucidate the role of GHRH in regulating GH secretion.
  • To discuss the clinical applications of GHRH in GH excess and deficiency states.

Main Methods:

  • Literature review of GHRH discovery and characterization.
  • Analysis of GHRH's physiological role in GH regulation.
  • Examination of clinical studies on GHRH use in pathological GH conditions.

Main Results:

  • GHRH plays a pivotal role in the hypothalamic-pituitary-somatotropic axis.
  • Clinical utility is demonstrated in diagnosing the etiology of GH deficiency, often linked to hypothalamic GHRH deficiency.
  • Experimental GHRH therapy in GH-deficient children shows encouraging results for accelerating linear growth via endogenous GH stimulation.

Conclusions:

  • GHRH is essential for understanding and managing growth hormone regulation.
  • It serves as a valuable diagnostic tool for GH deficiency.
  • GHRH holds therapeutic potential for GH deficiency, promoting natural GH secretion and growth acceleration.
