Herein, our findings indicated that knockdown of SET led to repression of migration and invasion, upregulation of epithelial marker (E-cadherin), and downregulation of mesenchymal markers (N-cadherin/Vimentin) in NSCLC cells, which recapitulated miR-1915-3p-induced inhibitory effects on cell migration, invasion and EMT process through JNK/c-Jun and NF-κB signaling pathways. Here, CDH1 is linked to non-small cell lung carcinoma.
