Background MALAT 1 is recognized as an oncogenic lnc RNA in various malignancies. However, its expression and function in oral tongue squamous cell carcinoma are still unknown. This study aims to investigate the expression and function of MALAT 1 in TSCC tissues and cells. Materials and Methods qPCR was performed to detect the expression of MALAT 1. MALAT 1 was suppressed and upregulated by plasmid transfection in TSCC cells, and then cell migration, invasion, EMT , and apoptosis were analyzed. Results Lnc RNA MALAT 1 was upregulated in TSCC tissues and correlated with cervical lymph node metastasis in TSCC patients. Moreover, MALAT 1 induced cell migration, invasion, EMT , and inhibited apoptosis by modulating Wnt/β‐catenin signaling pathway. Finally, inhibiting Wnt/β‐catenin signaling pathway attenuated the effect of exogenous MALAT 1. Conclusion In summary, upregulated MALAT 1 in TSCC promoted EMT and inhibited cell apoptosis by modulating Wnt/β‐catenin signaling pathway.
