Translational research has led to better understanding of molecular pathways and increased the interest in targeted therapy; For example, cancer cells can express epidermal growth factor receptor (EGFR), which stimulates cell proliferation, as well as vascular endothelial growth factor receptor (VEGFR), enabling vessel formation for growth,49,50 and EGFR signaling might promote resistance to radiotherapy. Here, EGFR is linked to cancer.
