IGF1 (Insulin-like growth factor 1), also known as growth regulator C, is a small peptide consisting of 70 amino acids. Similar to insulin, IGF-1 has A and B chains linked by disulfide bonds, and the C peptide region has 12 amino acids. Approximately 98% of IGF-1 binds to IGF-BP, of which IGFBP-3 is the most abundant protein, binding 80% of IGF1. IGF-1 is mainly produced by the liver as an endocrine hormone and in a paracrine/autocrine manner in target tissues, stimulated by growth hormone (GH) and can be delayed by failure of undernutrition, growth hormone insensitivity, lack of growth hormone receptors or GH receptors.
IGF-1 stimulates the growth of the whole body and acts on almost every growth-promoting effector cell in the body, especially skeletal muscle, cartilage, bone, liver, kidney, nerve, skin, hematopoiesis, and lung cells. Except for the similar effects of insulin (Figure 1), IGF-1 also regulates cellular DNA synthesis, besides activating IGF-II gene expression. Due to the important effects of IGF1 on growth and development, it is clear that the imbalance of the IGF system can affect many different conditions, including normal growth, central nervous system diseases (e.g. Alzheimer's disease), diabetes, and even cancer.

In addition, IGF-1 is an important signaling molecule for cancer cell transformation and proliferation, and IGF-1/IGF-1R binding and activation are key steps for downstream events, including mitosis and inhibition of apoptosis. When IGF-1 binds to IGF-1R, tyrosine kinase activates the PI3K-AKT pathway regulating cellular metabolism, apoptosis, cell adhesion and angiogenesis. Studies have shown that inhibition of IGF-1R activation by small molecule inhibitors or biologics may be an important step in identifying viable cancer therapies. And now, the IGF protein family remains a viable target for new therapeutic agents.
