Abstract

The objective of the present study was to investigate the long non‑coding RNA (lncRNA) and mRNA expression profiles that are associated with the invasion and metastasis of papillary thyroid carcinoma (PTC). Transwell invasion assays were used to screen three highly invasive sub‑strains of the human PTC IHH4 cell line: IHH4‑M1, IHH4‑M2 and IHH4‑M3. In addition, tumor‑bearing nude mice were used to identify the invasive and metastatic capacity of the three sub‑strains. Agilent lncRNA microarray chips were used to screen 795 differentially expressed lncRNAs and 788 differentially expressed mRNAs. A total of 10 lncRNAs and 10 mRNAs were randomly selected for RT‑qPCR validation to confirm that the results were consistent with the microarray chips, suggesting that the results of the microarray chip analysis were relatively accurate. Gene ontology enrichment‑based cluster analysis revealed that the differentially expressed genes were mainly associated with steroid biosynthesis, bioadhesion, intercellular adhesion and other metastasis‑associated biological processes. The results of the pathway cluster analysis identified that the differentially expressed genes were associated with tumor metastasis‑associated signaling pathways, including the cholesterol metabolic signaling pathway, the sterol regulatory element‑binding protein signaling pathway and the integrin signaling pathway, suggesting that lncRNA may regulate PTC metastasis through various signaling pathways. The present study screened and constructed PTC metastasis‑associated lncRNA and mRNA expression profiles, and it provides a molecular basis for the future study of high‑risk molecular markers of PTC.
