Background: Increasing studies highlight the crucial role of long non-coding RNAs (lncRNAs) in carcinogenesis of various human cancer types, including esophageal cancer (ESCA). Long intergenic non-coding RNA 00460 (Linc00460), a novel oncogenic lncRNA, has been reported to accelerate ESCA cell growth. This study aimed to investigate the role and possible regulatory mechanism of linc00460 in ESCA metastasis. Methods: Bioinformatics analysis and quantitative real time polymerase chain reaction (qRT-PCR) were used to detect linc00460 expression in ESCA. Wound healing assay, Transwell assay and Western blot were utilized to examine migration, invasion and epithelial-mesenchymal transition (EMT) of ESCA cells. The direct binding effect between linc00460 and microRNA-1224-5p (miR-1224-5p) was evaluated by the dual luciferase reporter assay. Results: In this study, we discovered that lncRNA linc00460 was obviously over-expressed in ESCA, both in tissues and cell lines. Down-regulation of linc00460 significantly suppressed the metastatic potential (including cell migration and invasion) and EMT of ESCA cells. In addition, miR-1224-5p, a potential tumor suppressor, was negatively correlated with linc00460 in ESCA. Linc00460 and miR-1224-5p could bind directly in ESCA cells. Inhibition of miR-1224-5p partially abrogated the effects of linc00460 decrease on metastatic potential and EMT of ESCA cells. Conclusions: Taken together, linc00460 may function as a molecular sponge to adsorb miR-1224-5p, thereby promoting ESCA metastasis and EMT. Our findings suggest that linc00460/miR-1224-5p is a possible clinical target for ESCA.
