Abstract

Areca nut chewing is an important risk factor for developing tongue squamous cell carcinoma (TSCC), although the underlying molecular mechanism is unknown. To determine the potential molecular mechanisms of areca nut chewing‑induced TSCC, the present study performed whole‑genome detection with five pairs of TSCC and adjacent normal tissues, via mRNA‑ and long non‑coding (lnc)RNA‑gene chip analysis. A total of 3,860 differentially expressed genes were identified, including 2,193 lncRNAs and 1,667 mRNAs. Gene set‑enrichment analysis revealed that the differentially expressed mRNAs were enriched in chromosome 22q13, 8p21 and 3p21 regions, and were regulated by nuclear factor kappa B (NF‑κB) and interferon regulatory factors (IRFs). The results of ingenuity pathway analysis revealed that these mRNAs were significantly enriched for inflammatory immune‑related signaling pathways. A co‑expression network of mRNAs and lncRNAs was constructed by performing weighted gene co‑expression network analysis. The present study focused on NF‑κB‑, IRF‑ and Th cell‑signaling pathway‑related lncRNAs and the corresponding mRNA‑lncRNA regulatory networks. To the best of our knowledge, the present study was the first to investigate differential mRNA‑ and lncRNA‑expression profiles in TSCCs induced by areca nut chewing. Inflammation‑related mRNA‑lncRNA regulatory networks driven by IRFs and NF‑κB were identified, as well as the Th cell‑related signaling pathways that play important carcinogenic roles in areca nut chewing‑induced TSCC. These differentially expressed mRNAs and lncRNAs, and their regulatory networks provide insight for further analysis on the molecular mechanism of areca nut chewing‑induced TSCC, candidate molecular markers and targets for further clinical intervention.
