What is the Meaning of IGF-1 Response?

The IGF-1 response refers to the systemic and cellular actions that follow the production and release of Insulin-like Growth Factor 1, a crucial mediator of growth hormone's anabolic effects. This response is central to the Growth Hormone/IGF-1 axis, governing cell proliferation, tissue repair, and overall body growth. A robust IGF-1 response is essential for maintaining lean body mass, bone mineral density, and metabolic health, particularly throughout adulthood. Monitoring this response is a key diagnostic tool for evaluating the functional status of the somatotropic axis.

What is the Origin of IGF-1 Response?

The term originates from the initial discovery that this peptide possessed insulin-like metabolic effects, hence the name Insulin-like Growth Factor. It is primarily synthesized in the liver following stimulation by Growth Hormone (GH) from the pituitary gland. The concept of the response emphasizes the downstream biological effects of this single hormone on nearly every cell type in the body.

What is the Mechanism of IGF-1 Response?

The response is initiated when Growth Hormone binds to its receptor, primarily in the liver, triggering an intracellular signaling cascade involving the Janus Kinase 2 (JAK2) and STAT5B pathway, which ultimately leads to the transcription and release of IGF-1. Once circulating, IGF-1 binds to its own receptor, IGF1R, a receptor tyrosine kinase, on target cells. This binding activates major anabolic pathways, including the PI3K/Akt and RAS/MAPK cascades, which promote protein synthesis, inhibit apoptosis, and drive cell growth and differentiation.
