Ontology highlight
ABSTRACT: Background:Various evidences showed that abnormally expressed long non-coding RNAs (lncRNAs) play important roles in the tumorigenesis and progression of malignancies. However, the exact role and regulatory mechanism of lncRNA TP73-AS1 in the pathogenesis and progression of lung adenocarcinoma remain to be further elucidated. Purpose:The aim of this study was to investigate the functional role and underlying mechanism of lncRNA TP73-AS1 in lung adenocarcinoma progression. Methods:RT-PCR assay was employed to detect TP73-AS1 expression in lung adenocarcinoma tissues and cells. The function of TP73-AS1 in lung adenocarcinoma progression was estimated by MTT assay, EdU assay, flow cytometry, Western blot, wound-healing assay and transwell assay. Results:LncRNA TP73-AS1 expression was significantly increased in lung adenocarcinoma tissues and cell lines. Moreover, functional assays revealed that silencing of lncRNA TP73-AS1 could attenuate cell proliferation, migration, invasion and epithelial-mesenchymal transition of lung adenocarcinoma, while enhanced expression of lncRNA TP73-AS1 led to the opposite results. Additionally, lncRNA TP73-AS1 knockdown could facilitate cell apoptosis and overexpression of lncRNA TP73-AS1 inhibited cell apoptosis. In addition, we further determined that lncRNA TP73-AS1 regulated cell metastasis through inducing the activation of Wnt/?-catenin signaling pathway in lung adenocarcinoma. Conclusion:Our results indicated that lncRNA TP73-AS1 may play an oncogenic role in lung adenocarcinoma progression, which provided a promising therapy strategy for the treatment of lung adenocarcinoma.
