What is the Meaning of IGF-1 Axis?

The IGF-1 Axis refers specifically to the downstream signaling pathway activated by Growth Hormone (GH), resulting in the production of Insulin-like Growth Factor 1, predominantly synthesized by the liver in response to GH stimulation. This pathway is central to anabolic and anti-catabolic processes.

What is the Origin of IGF-1 Axis?

The name is an acronym for Insulin-like Growth Factor 1, denoting its structural homology to insulin, and 'Axis' defining its integrated pathway structure from pituitary to peripheral tissues. It represents the primary mediator of GH's systemic effects.

What is the Mechanism of IGF-1 Axis?

Following GH release, IGF-1 acts in a paracrine and endocrine manner, binding to its own receptor to promote protein synthesis, cellular proliferation, and inhibit apoptosis in target cells, including muscle and bone tissue. This signaling cascade is crucial for tissue maintenance and is often measured clinically to assess GH axis efficacy.
