Lung cancer is an significant cause of death worldwide, and non–small‐cell lung cancer (NSCLC) is the most common type of lung cancer. MicroRNAs (miRNAs) have been identified to play key roles in NSCLC development. Recently, it has been reported that miR‐605‐5p is a cancer‐related miRNA in several types of tumors. In this study, we study the role of miR‐605‐5p in NSCLC cells. We find that miR‐605‐5p is upregulated in NSCLC cells. Overexpression of miR‐605‐5p significantly promotes lung cancer invasion and migration in H460 and H1299 cells. Besides this, miR‐605‐5p also promotes lung cancer cell carcinoma proliferation and metastasis in vivo. However, downregulation of miR‐605‐5p inhibits cell invasion and migration by inhibiting lung cancer cell carcinoma proliferation and metastasis. In addition, the luciferase report assay identifies 3′‐untranslated region tumor necrosis factor α‐induced protein 3 (TNFAIP3) as a target of miR‐605‐5p. Silencing of TNFAIP3 promotes invasion and proliferation in lung cancer. In addition, the knockdown of TNFAIP3 restores the significant decrease in invasion and proliferation in miR‐605‐5p‐inhibitor–transfected lung cancer cells. In conclusion, miR‐605‐5p promotes invasion and proliferation by targeting TNFAIP3 in NSCLC, and may provide possible biomarkers for NSCLC therapy.
