Abstract
Long noncoding RNAs have been reported to be important regulators in numerous cancers. In this study, we found that HOXC13 antisense RNA (HOXC13-AS) was highly expressed in head and neck squamous carcinoma (HNSC) tissues in The Cancer Genome Atlas database. Nasopharyngeal carcinoma (NPC) belongs to HNSC. Therefore, we further investigated the potential role of HOXC13-AS in NPC. Quantitative reverse transcription polymerase chain reaction examination revealed that HOXC13-AS was markedly upregulated in NPC tissues and cell lines. Furthermore, HOXC13-AS was identified as an independent prognosis factor by Cox regression analyses. Subsequently, functional assay revealed that knockdown of HOXC13-AS impaired cell proliferation, migration, and invasion. Mechanistically, RIP and luciferase reporter analysis confirmed that miR-383-3p was a target of HOXC13-AS. Besides, high mobility group AT-hook 2 (HMGA2) was proved to be a target of miR-383-3p in NPC. Finally, rescue assays demonstrated that HOXC13-AS functioned as a competing endogenous RNAs to enhance the expression of HMGA2 via sponging miR-383-3p. This study suggested that HOXC13-AS exerted oncogenic function in NPC via regulating miR-383-3p/HMGA2 axis, indicating HOXC13-AS may be a potential therapeutic target for patients with NPC.
