Résumé
Epithelial-mesenchymal transition (EMT) has an important function in cancer. Recently, microRNAs have been reported to be involved in EMT by regulating target genes. miR-942 is considered a novel oncogene in esophageal squamous cell carcinoma. However, its role in non-small-cell lung cancer (NSCLC) has not been investigated. In this study, the expression of miR-942 in NSCLC patients tumor and paired adjacent tissues were assessed by quantitative real-time polymerase chain reaction and in situ hybridization. Transwell, wound healing, tube formation, and tail vein xenograft assays were conducted to assess miR-942's function in NSCLC. Potential miR-942 targets were confirmed using dual-luciferase reporter assays, immunohistochemistry, immunoblot, and rescue experiments. The results showed miR-942 is relatively highly expressed in human NSCLC tissues and cells. In vitro assays demonstrated that overexpression of miR-942 promoted cell migration, invasion, and angiogenesis. Tail vein xenograft assays suggested that miR-942 contributed to NSCLC metastasis in vivo. Three bioinformatics software was searched, and BARX2 was predicted as a downstream target of miR-942. Direct interaction between them was validated by dual-luciferase assays. Rescue experiments further confirmed that BARX2 overexpression could reverse functional changes caused by miR-942. Moreover, miR-942 increased EMT-associated proteins N-cadherin and vimentin by inhibiting BARX2, while E-cadherin expression is reduced. In summary, this study reveals that miR-942 induces EMT-related metastasis by directly targeting BARX2, which may provide a potential therapeutic strategy for NSCLC.
