Abstract

Src is a member of a superfamily of membrane-associated nonreceptor protein tyrosine kinases. It is stimulated by receptors of growth hormone, cytokines, and adipokines, and it regulates multiple signaling pathways, including phosphatidylinositide 3 kinase-Akt, mitogen-activated protein kinase, signal transducer and activator of transcription 3, interleukin 8, and vascular endothelial growth factor pathways, and cytoskeletal pathways to cause a cascade of cellular responses. Eighty percent of patients with colon cancer overexpress Src in tumor tissue. Evidence has shown that the overexpression of Src in colon cancer accelerates metastasis and causes chemotherapeutic drug resistance via multiple downstream signaling pathways. Therefore, the inhibition of Src may be useful for the treatment of colon cancer. However, the inhibition of Src may also weaken immune responses that are essential for the eradication of cancer cells. Overcoming the problem of inhibiting Src in cancer cells while retaining immune system efficacy is the key to the successful application of Src-inhibition therapy. Different Src family members are used by the immune system and colon cancer. This differential use may provide a good opportunity to develop Src family member-specific inhibitors to avoid immune inhibition.
