ABSTRACT
Increasing studies have revealed that long noncoding RNAs (lncRNAs) might play vital roles in the development and progression of various diseases including viral infectious diseases. However, the expression and biological functions of lncRNAs in chronic hepatitis B virus (HBV) infection remain largely unknown. Therefore, lncRNA microarray was performed to analyze the lncRNAs' and messenger RNAs' (mRNAs) expression profiles in liver tissues from patients with chronic HBV infection. Subsequently, a comprehensive bioinformatics analysis was conducted to investigate the potential functions of the differentially expressed genes. As a result, a total of 203 differentially expressed lncRNAs and 180 mRNAs were identified in chronic HBV infection. The expressions of five differentially expressed lncRNAs were further validated using quantitative real-time polymerase chain reaction. Gene ontology, pathway analysis, and gene set enrichment analysis revealed that differentially expressed lncRNAs might be mainly be involved in cytokine-cytokine receptor interaction and varied biotransformation processes, including fatty acid metabolism, amino acid metabolism, carbon metabolism, and drug metabolism. Additionally, coexpression networks between differentially expressed lncRNAs and mRNAs were constructed to reveal the hub regulator and analyze the functional pathways. This study provided an overview of lncRNA and mRNA expression in liver tissues from patients with chronic HBV infection. These differentially expressed lncRNAs might play crucial roles in the pathogenesis and progression of chronic HBV infection, which deserve further investigation.
