In a recent study, Garofalo et al. demonstrated that RTK of EGFR and c-MET could induce miR-30b/30c/221/222 expressions, and an upregulation of miR-30b/30c/221/222 induced resistance to gefitinib in lung cancer cells by the regulation of BCL2-like 11 (BIM), phosphatase and tensin homolog (PTEN), and apoptotic peptidase activating factor 1 (APAF-1) expressions. Here, APAF1 is linked to lung cancer.
