EGFR and cancer: It may be responsible for the stimulation of cancer cell proliferation by the formation of activating complexes with growth factor receptors such as with the Epidermal Growth Factor Receptor (EGFR), decreasing the autophagy process by downregulating the keratinocyte growth factor receptor/fibroblast growth factor receptor 2b (KGFR/FGFR2b) signalling, and promoting the accumulation of cells with abnormal DNA genetic mutations by decreasing apoptosis [17].
