Similarly, decreased miR-19a expression in gefitinib-resistant NSCLC cell lines contributes to cell migration, EMT, and gefitinib resistance by negatively regulating c-Met expression and blocking its downstream pathways (such as PI3K-AKT and RAS-ERK pathways) (Cao et al., 2017). The gene discussed is AKT1; the disease is non-small cell lung carcinoma.
