IGF1R Gene Editing    

The Insulin-like Growth Factor Receptor (IGF1R), also known as CD221/JTK13, is a transmembrane receptor found on the surface of human cells and belongs to the large class of tyrosine kinase receptors, mediates the effects of IGF-1. IGF1R is activated by hormone called insulin-like growth factor 1 (IGF-1), a polypeptide protein hormone similar to insulin in molecular structure, and by the related growth factor IGF-2. IGF1R is a hetero-tetrameric protein with two identical extracellular α-subunits and two transmembrane β-subunits. The extracellular domain contains a cysteine-rich IGF-binding site. The transmembrane domain contains tyrosine kinase activity which depends on an ATP-binding site (lys1003) and a cluster of three tyrosine residues at positions 1131, 1135, and 1136. Activation of IGF1R initiates a cascade of downstream signaling pathways (Figure 1).

The IGF1R signaling pathway, while cell type-specific, is critical for cell proliferation, growth, and survival. Lots of studies have showed that the IGF1R is implicated in a number of cancers including breast, prostate, and lung cancers. As a result, IGF1R appears to be a key factor in numerous cancer therapies and a potential therapeutic target for many different malignancies. IGF1R signaling is a complex and tightly regulated network, interacting with and influencing various cellular components including ER, EGFR, HER-2, and the DNA damage response pathway. It is through these interactions that IGFIR appears allow cancer cells to resist cytotoxicity and targeted therapies. Although many of these therapeutic agents are now undergoing clinical trials, how most effectively inhibit IGF1R action and enhance the response of tumor cells to treatment still requires further research. There is still a long way to go in terms of drug development for this pathway.
