The Role of circRNA-miRNA-mRNA Regulatory Network and its Potential Biomarker Function in Colorectal Cancer.
Background: Revealing the process and mechanism of colorectal cancer will facilitate the discovery of new biomarkers and contribute to the development of targeted drugs.
Objectives: This study aimed to explore the potentially functional circRNA-miRNA-mRNA network in colorectal cancer (CRC), and further explore its mechanism.
Methods: Bioinformatics analysis was used to identify the differentially expressed circRNAs and mRNAs. Gene set enrichment analysis and KEGG pathways analysis were used to screen out the differentially expressed genes and observe crucial pathways that might have a strong association with CRC. Then, a network targeting circRNA, miRNA, and mRNA has been built by using the Cytoscape software. In addition, the expression of circRNA_0001573, miR-382-5p, and FZD3 was detected by qRT-PCR in CRC tissues and cells (SW480, HCT116, and HT29).
Results: Abnormal expressions of circRNAs and mRNAs were obtained by bioinformatics analysis and visualized by Volcano plot and Heatmap. A series of highly correlated pathways were enriched by KEGG analysis. The interaction network of circRNA_0001573/miR-382-5p/FZD3 axis was predicted. The expressions of circRNA_0001573 and FZD3 were highly upregulated and the miR- 382-5p expression level was decreased in CRC tissues and cell lines (SW480, HCT116, and HT29).
Conclusion: Our study suggests that circRNA_0001573 and circRNA_0001573/miR-382-5p/FZD3 regulatory networks might provide a potential diagnosis for colorectal cancer.
期刊介绍：
Protein & Peptide Letters publishes letters, original research papers, mini-reviews and guest edited issues in all important aspects of protein and peptide research, including structural studies, advances in recombinant expression, function, synthesis, enzymology, immunology, molecular modeling, and drug design. Manuscripts must have a significant element of novelty, timeliness and urgency that merit rapid publication. Reports of crystallization and preliminary structure determination of biologically important proteins are considered only if they include significant new approaches or deal with proteins of immediate importance, and preliminary structure determinations of biologically important proteins. Purely theoretical/review papers should provide new insight into the principles of protein/peptide structure and function. Manuscripts describing computational work should include some experimental data to provide confirmation of the results of calculations.
Protein & Peptide Letters focuses on:
Structure Studies
Advances in Recombinant Expression
Drug Design
Chemical Synthesis
Function
Pharmacology
Enzymology
Conformational Analysis
Immunology
Biotechnology
Protein Engineering
Protein Folding
Sequencing
Molecular Recognition
Purification and Analysis
