Construction of an oesophageal cancer-specific ceRNA network based on miRNA, lncRNA, and mRNA expression data

World J Gastroenterol. 2018 Jan 7;24(1):23-34. doi: 10.3748/wjg.v24.i1.23.

Abstract

Aim: To explore the expression profiles of microRNAs (miRNAs), long non-coding RNAs (lncRNAs), and mRNAs in oesophageal squamous cell carcinoma (ESCC) in order to construct an oesophageal cancer-specific competing endogenous RNA (ceRNA) network.

Methods: In this work, the expression data of miRNAs, lncRNAs, and mRNAs in ESCC were obtained. An oesophageal cancer-specific ceRNA network was then constructed and investigated.

Results: CeRNAs have the ability to reduce the targeting activity of miRNAs, leading to the de-repression of specific mRNAs with common miRNA response elements. CeRNA interactions have a critical effect in gene regulation and cancer development.

Conclusion: This study suggests a novel perspective on potential oesophageal cancer mechanisms as well as novel pathways for modulating ceRNA networks for treating cancers.

Keywords: Competing endogenous RNA; Long non-coding RNA; MicroRNA; Oesophageal squamous cell carcinoma; mRNA.
