RETRACTED ARTICLE: Integrative analysis of the circRNA–miRNA regulatory network in atrial fibrillation

We aimed to investigate the circRNA–miRNA regulatory network in atrial fibrillation (AF) by using Cytoscape and HMDD v3.0. Finally, 120 differentially expressed circRNAs in peripheral blood monocytes of 4 AF patients were preliminarily screened by circRNA microarray. circRNA_4648, circRNA_4631, and...

Description
Summary:We aimed to investigate the circRNA–miRNA regulatory network in atrial fibrillation (AF) by using Cytoscape and HMDD v3.0. Finally, 120 differentially expressed circRNAs in peripheral blood monocytes of 4 AF patients were preliminarily screened by circRNA microarray. circRNA_4648, circRNA_4631, and circRNA_2875 were the first four circRNAs with the most binding nodes in the circRNA–miRNA network. The top three most frequent miRNAs for up-regulated circRNAs were hsa-miR-328 that interacted with 5 up-regulated circRNAs, hsa-miR-4685-5p with 4 up-regulated circRNAs, hsa-miR-3150a-3p, hsa-miR-4649-5p, hsa-miR-4783-3p, and hsa-miR-8073 with 3 up-regulated circRNAs,, while the top three most frequent miRNAs for down-regulated circRNAs were hsa-miR-328 that interacted with 14 down-regulated circRNAs, hsa-miR-4685-5p with 11 down-regulated circRNAs and hsa-miR-661 with 9 down-regulated circRNAs. According to HMDD v3.0, five up-regulated and eleven down-regulated circRNAs were found to interact with AF related miRNAs. These results indicated the possible regulatory network between circRNAs and miRNAs in the pathogenesis of AF.
