PG - 7337-7345 LID - 10.2147/OTT.S212749 [doi] AB - PURPOSE: To investigate the role of zinc finger E‑box‑binding homeobox 2 antisense RNA 1 (ZEB2-AS1) in regulating laryngeal squamous cell carcinoma (LSCC) progression. PATIENTS AND METHODS: In this retrospective study, we included all patients who underwent a surgical operation at The First Hospital of Qiqihaer City for LSCC. Then, we compared the expression of ZEB2-AS1 in LSCC tissues and paired healthy tissues. Besides, we also performed a series of functional assays, CCK8 assays, colony formation assays, and transwell assays to examine the functions of LSCC cells after knockdown of ZEB2-AS1. Through bioinformatics analysis, we predicted that ZEB2-AS1 binds to miR-6840-3p and targets PLXNB1. RESULTS: We indicated that the expression of ZEB2-AS1 was higher in LSCC tissues compared to the paired adjacent tissues, and ZEB2-AS1 was also highly expressed in LSCC cell lines. Furthermore, we discovered that ZEB2-AS1 promoted cell proliferation, migration and invasion and was associated with poor prognosis. To find the mechanism, we performed bioinformatics analysis. We identified that ZEB2-AS1 binds to miR-6840-3p and targets PLXNB1. Additionally, miR-6840-3p overexpression or knockdown of PLXNB1 decreased the abilities of cell migration and invasion. CONCLUSION: These findings demonstrated that overexpression of ZEB2-AS1 promotes LSCC progression. Overexpression of miR-6840-3p or downregulation of PLXNB1 can abrogate ZEB2-AS1-mediated LSCC malignant development. CI - (c) 2019 Xu et al.
