摘要: The involvement of Axl kinase in non-small cell lung cancer's (NSCLC) acquired resistance to tyrosine inhibitors (TKIs) gefitinib or erlotinib has been identified recently, but the mechanism by which contributes TKI is largely unknown. MicroRNAs (miRNAs) repress gene expression and their critical role tumorigenesis implicated. To investigate miRNAs Axl-mediated resistance, we examined miRNA changes gefitinib-resistant cancers. A panel kinase-altered was identified. In this study, validate report that miR-374a miR-548b modulated have essential roles cycle arrest, gefitinib-induced apoptosis, epithelial-to-mesenchymal transition, migration cancer cells vitro vivo targeting Wnt5a CCNB1 genes, respectively. Of clinical significance, high low are associated with poor disease-free survival postoperatively. These findings indicate modulation specific may provide a therapeutic target treat reverse NSCLC future.
