EGFR and neoplasm: For example, miR-7 inhibits the invasion and metastasis of cancer cells by regulating Egfr expression [24–26]; miR-145 inhibits cell proliferation of lung adenocarcinoma by targeting Egfr [27], miR-146a suppresses tumor growth and progression by targeting Egfr in prostate cancer [28]; miR-27a regulates non-small lung cancer by targeting Egfr [29].
