Growth Hormone Signals

Meaning

Growth Hormone Signals encompass the complex cascade of endocrine and paracrine messages initiated by the pulsatile secretion of Growth Hormone (GH) from the anterior pituitary gland. These signals are critical for regulating body composition, stimulating lipolysis, promoting protein synthesis, and supporting tissue repair and regeneration. Upon release, GH acts directly on target tissues and indirectly by stimulating the liver to produce Insulin-like Growth Factor 1 (IGF-1), which mediates many of its anabolic effects. The strength and frequency of these signals are paramount indicators of somatotropic axis function, significantly influencing metabolic health and physiological aging.
