What is the Meaning of IGF-1 Pathway?

The intricate endocrine signaling cascade initiated by Insulin-like Growth Factor 1 (IGF-1), a peptide hormone structurally homologous to insulin. This pathway is a critical component of the somatotropic axis, mediating many of the growth-promoting and anabolic effects of growth hormone (GH) in the body. The IGF-1 pathway is vital for cellular proliferation, differentiation, and tissue maintenance throughout the lifespan. Its activity is closely monitored in clinical contexts related to growth, metabolism, and aging.

What is the Origin of IGF-1 Pathway?

The concept originated in endocrinology following the discovery of IGF-1, initially called "somatomedin C," a factor that mediates the effects of somatotropin (Growth Hormone). The term 'pathway' refers to the sequence of biochemical reactions and interactions within the cell. This axis is a cornerstone of our understanding of human growth and development.

What is the Mechanism of IGF-1 Pathway?

Growth Hormone released from the pituitary stimulates the liver to produce IGF-1, which then acts as an endocrine hormone. IGF-1 binds to its specific receptor, IGF-1R, initiating an intracellular cascade, often involving the PI3K/Akt pathway, that promotes cell survival and protein synthesis. This powerful anabolic signaling mechanism is central to bone density, muscle mass maintenance, and metabolic health. Nutritional status and insulin sensitivity are key modulators of this pathway's activity.
