Reporter brief
Systematic review describes growth hormone receptor signaling mechanisms and Laron syndrome as a model of GH deficiency effects.
What happened
This systematic review examines the growth hormone-IGF-I axis and its role in growth, metabolism, and tissue homeostasis. The review synthesizes knowledge of growth hormone receptor structure, signal transduction pathways (JAK2-STAT5, MAPK/ERK, PI3K-AKT-mTOR), and discusses Laron syndrome—a condition of lifelong GHR deficiency—as a human model showing that GH deficiency associates with short stature but also enhanced insulin sensitivity, preserved glucose homeostasis, increased adiposity, and low cancer incidence.
