What is the Meaning of Insulin-Like Growth Factor 1?

Insulin-Like Growth Factor 1 (IGF-1) is a potent polypeptide hormone that shares structural homology with insulin and functions as the primary mediator of Growth Hormone (GH) action in the body. It is crucial for promoting systemic growth, particularly in skeletal and muscular tissues, and plays a vital role in cellular repair, metabolic regulation, and neuroprotection. Clinicians often use circulating levels of IGF-1 as a reliable indicator of overall Growth Hormone status.

What is the Origin of Insulin-Like Growth Factor 1?

The name reflects its structural similarity to insulin and its function as a factor that promotes cellular and tissue growth. Its discovery was key to elucidating the mechanism by which GH exerts many of its anabolic effects, establishing the GH-IGF-1 axis as a major endocrine pathway. The term is a cornerstone of growth and metabolic endocrinology.

What is the Mechanism of Insulin-Like Growth Factor 1?

Growth Hormone stimulates the liver, and to a lesser extent other peripheral tissues, to synthesize and secrete IGF-1 into the circulation. IGF-1 then binds to the high-affinity IGF-1 receptor on target cells, initiating an intracellular signaling cascade that stimulates protein synthesis, inhibits programmed cell death, and promotes cell proliferation. This endocrine loop is subject to negative feedback regulation by IGF-1 itself, ensuring precise and tightly controlled growth and metabolic processes.
