Current evidence has unveiled that long non-coding RNAs (lncRNAs) are pivotal regulators in the development of cancers. This study aimed to investigate the potential mechanisms of LINC01224 in esophageal squamous cell carcinoma (ESCC) cells. RT-qPCR analysis was done to test LINC01224 expression in ESCC cells. Functional assays were conducted to assess the influences of LINC01224 on ESCC cell functions. Mechanism assays were carried out to detect the regulatory mechanisms of LINC01224 at post-transcriptional and transcriptional levels. Briefly, LINC01224 expression was remarkably high in ESCC cells. LINC01224 silence restricted the proliferative, migratory, and invasive capabilities of ESCC cells. Moreover, LINC01224 could combine with miR-6884-5p by acting as a ceRNA. Further, DVL3 was proved to be targeted by miR-6884-5p. Importantly, LINC01224 could switch on Wnt/beta-catenin signaling pathway by via enhancing DVL3 expression. Additionally, E2F1 could serve as a transcription factor to stimulate LINC01224 transcription. In summary, our study elucidated that E2F1-activated LINC01224 regulated miR-6884-5p/DVL3 to actuate the Wnt/beta-catenin signaling pathway, which facilitates multiple phenotype of ESCC cells, including proliferation, migration, and invasion. Our findings might offer potential therapeutic targets for ESCC treatment.
