What is the Meaning of IGF-1 Levels?

IGF-1 Levels, or Insulin-like Growth Factor 1 concentrations, represent a circulating peptide hormone primarily synthesized by the liver in response to Growth Hormone (GH) stimulation. This biomarker is a crucial indicator of the functional status of the GH/IGF axis, reflecting overall anabolic drive and tissue maintenance capacity. Clinically, suboptimal levels can suggest GH resistance or pituitary dysfunction, impacting growth, body composition, and cellular repair rates. We interpret these values in conjunction with GH dynamics.

What is the Origin of IGF-1 Levels?

IGF-1 was originally identified due to its structural similarity to insulin and its growth-promoting effects in biological assays. Its physiological link to the somatotropic axis, mediated by Growth Hormone, established its importance in developmental and maintenance physiology. The term highlights the downstream effector molecule responsible for most GH-mediated anabolic actions.

What is the Mechanism of IGF-1 Levels?

The primary mechanism involves IGF-1 binding to the IGF-1 receptor (IGF-1R) on target cells, activating the PI3K/Akt and MAPK signaling pathways. This activation promotes cell proliferation, differentiation, and survival, which is vital for skeletal and soft tissue remodeling. Insulin-like Growth Factor Binding Proteins (IGFBPs) regulate the bioavailability of circulating IGF-1, controlling how much active ligand reaches the tissues. Therefore, IGF-1 levels are a functional readout of the entire somatotropic axis's efficiency.
