EGFR and cancer: Studies conducted in both in vitro with Mice SKBR3 cells and MCF‐7 cells, respectively, have shown upregulation of WDR7‐7 (WD repeat domain 7) and downregulation of SRC (a proto‐oncogene), EGFR (epidermal growth factor receptor), ERK1/2 (extracellular signal‐related kinase 1/2), Akt phosphorylation that result in inhibiting proliferation and growth of cancer cells.49
