ceRNA network, GO terms, and KEGG pathway analysis of the screened exosomal circRNAs. a The cirRNA–miRNA–mRNA networks based on the selected five circRNAs, 28 miRNAs, and 31 mRNAs. b KEGG enrichment scatter plot for the target genes of the exosomal circRNAs. The exosomal circRNA target genes were grouped into gene pathways using KEGG enrichment analysis. The size of the circle is proportional to the number of enriched genes. KEGG, Kyoto Encyclopedia of Genes and Genomes. c GO enrichment summary of exosomal circRNA target genes. The GO enrichment analysis grouped the exosomal circRNA target genes into functional groups. The red, green, and blue columns represent the biological processes, cellular component, and molecular function, respectively. GO, Gene Ontology
