EGFR and cancer: MiRNAs (miR-21, miR-210, miR-486,miR-126, miR-126*, miR-138, miR-521, miR-451, miR-30d, and miR-30a) were altered in the same direction in cancer compared to non-neoplastic tissues, implying that EGFR mutations may reinforce the aberrant regulation of some miRNAs linked to lung carcinogenesis in never-smokers.
