OBJECTIVE: The aim of this study was to investigate the potential role of LINC00511 in esophageal cancer (ECa), and to explore its underlying mechanism through in vitro cell experiments.

PATIENTS AND METHODS: LINC00511 expression in ECa was analyzed by GEPIA database and verified by real-time fluorescence quantitative polymerase chain reaction (qPCR). The bioinformatics website was used to analyze the miRNAs that can bind to LINC00511, and the regulatory relationship between them was verified through Luciferase assay, qPCR as well as Western blotting analysis. Then, the impacts of LINC00511 and microRNA-150-5p on the proliferation or invasiveness of ECa cell lines Kyse30 and ECA109 were investigated by cell counting kit-8 (CCK-8) test and transwell experiment, respectively. Meanwhile, cell cycle and apoptosis were detected by flow cytometry.

RESULTS: Analysis results of the GEPIA database revealed that LINC00511 had a significant high expression in ECa tissue samples in comparison with normal control ones, which is consistent with qPCR results. Meanwhile, a significant negative correlation was found between LINC00511 and microRNA-150-5p. In brief, LINC00511 was able to bind to microRNA-150-5p and inhibited its expression. Besides, overexpression of LINC00511 enhanced ECa cell proliferation and migration, accelerated cell cycle, and suppressed cell apoptosis, while transfection with microRNA-150-5p mimics caused the opposite effects.

CONCLUSIONS: This study shows for the first time that LINC00511 modulates the progression of ECa by binding to microRNA-150-5p.
