A growing number of evidences has revealed that long non-coding RNAs (lncRNAs) have vital effect in the pathogenesis of esophageal squamous cell carcinoma (ESCC). In our work, we found that lncRNA FOXD2 adjacent opposite strand RNA 1 (FOXD2-AS1) was significantly increased in clinical ESCC samples and cell lines.The biological effect of FOXD2-AS1 on EC109 and KYSE150 cells showed that the low expression of FOXD2-AS1 inhibited the proliferation through CCK8 and colony formation assays, invasion by transwell chamber test, migration abilities by wound healing assay, and enhance apoptosis rates by flow cytometry assay.Through bioinformatics analysis and luciferase reporter assays, microRNA (miR)-204-3p was proved to be a target of FOXD2-AS1. We further confirmed that FOXD2-AS1 was the upstream inhibitor of miR-204-3p and the down-regulation of miR-204-3p reversed the repressive effects of low expression of FOXD2-AS1 on ESCC progression. In addition, inhibition of FOXD2-AS1 effectively suppressed the tumor growth.In general, our results suggested that FOXD2-AS1 may be of vital therapeutic importance for the treatment of ESCC patients. |
