In order to interrogate the role of miRNAs in the Axl-mediated acquired TKIs resistance in lung cancer, Wang et al. identified a panel of Axl kinase-altered miRNAs in lung cancer cells and experimentally validated that the Axl-induced miR-374a and miR-548b play a crucial role in cell cycle arrest, gefitinib-induced apoptosis, and EMT of gefitinib-resistant lung cancer cells by targeting Wnt5a and CCNB1 genes, respectively. This evidence concerns the gene CCNB1 and lung cancer.
