Izumchenko et al showed that expression levels of MIG6 and miR-200 were significantly correlated with EMT, as well as resistance to erlotinib in 25 cancer cell lines originating from different tissues; also the MIG6 mRNA/miR-200 ratio was inversely correlated with response to erlotinib in EGFR wild-type NSCLC patients [71]. Here, EGFR is linked to non-small cell lung carcinoma.
