Construction and functional enrichment analysis of the ceRNA network. a The ceRNA regulatory network in KIRC. Red octagons represent upregulated miRNAs, and Blue octagons represent downregulated miRNAs. Orange circles and squares stand for upregulated mRNAs and lncRNAs, respectively. Green circles and squares present downregulated mRNAs and lncRNAs, respectively. b Chord plot of GO enrichment analysis for the ceRNA network. The GO terms are shown and annotated on the right of the chord diagram, while the DEmRNAs in the ceRNA network are shown on the left. Red bricks represent upregulated genes, and blue bricks represent downregulated genes. c Sankey diagram of KEGG pathway analysis for the ceRNA network. Rectangles on the left of the Sankey plot represent the significant pathways, while rectangles on the right represent DEmRNAs in the ceRNA network
