OBJECTIVE: This study was conducted to investigate key lncRNAs involved in ceRNA network associated with laryngeal squamous cell carcinoma (LSCC). MATERIALS AND METHODS: Three mRNA datasets, two miRNA datasets and one lncRNA dataset of LSCC were downloaded from GEO database. Following the identification of differentially expressed mRNAs (DEmRNAs), miRNAs (DEmiRNAs) and lncRNAs (DElncRNAs) in LSCC compared with adjacent tissues, functional enrichment of DEmRNAs was performed. Then, construction of the ceRNA (DElncRNA-DEmiRNA-DEmRNA) regulatory network and functional analyses of all DEmRNAs in ceRNA regulatory network were conducted. Quantitative real-time polymerase chain reactions (qRT-PCR) was used to detect the expression levels of selected DEmRNAs, DEmiRNAs and DElncRNAs. RESULTS: A total of 3449 DEmRNAs, 40 DEmiRNAs, and 100 DElncRNAs were identified in LSCC. The ceRNA networks, which contained 132 DElncRNA-DEmiRNA pairs and 287 DEmiRNA-DEmRNA pairs, involving 44 lncRNAs, 3 miRNAs, and 271 mRNAs, were obtained. DEmRNAs in ceRNA regulatory networks were significantly enriched in Pathways in cancer, Prostate cancer and Aldosterone-regulated sodium reabsorption. Except for HCG22 and hsa-miR-1246, expressions of the others in the qRT-PCR results played the same pattern with that in our integrated analysis, generally. CONCLUSIONS: We concluded that HCG22/EGOT-hsa-miR-1275-FAM107A and HCG22/EGOT-hsa-miR-1246-GPD1L interaction pairs may play a central role in LSCC. This article is protected by copyright.
