Project description:In this study, we investigated the role of microRNAs and circular RNAs in Nasopharyngeal Carcinoma (NPC) by constructing a circRNA-miRNA-mRNA co-expression network and performing differential expression analysis on mRNAs, miRNAs, and circRNAs. By comparing the expression profile of non-cancerous immortalized nasopharyngeal epithelial cell lines and NPC cell lines, we identified differentially expressed coding and non-coding RNAs. By leveraging coexpression and miRNA target prediction tools, we constructed a ceRNA network composed of mRNAs, miRNAs, and circRNAs.
Project description:Long non-coding RNAs (lncRNAs) play important roles in the tumorigenesis and progression of cancers. However, the clinical significance of lncRNAs and their regulatory mechanisms in nasopharyngeal carcinogenesis (NPC) are largely unknown. In this study, we used the microarray analysis to study the different expression profiles of lncRNAs and mRNAs in human nasopharyngeal carcinoma tissues. We performed genome-wide lncRNAs expression in 3 pairs of NPC and normal nasopharynx tissues and identified 384 dysregulated lncRNAs (fold change ≥2 and P <0.05).
