Figure 6. Functional enrichment analysis towards this ceRNA network. Go annotation of lncRNAs-miRNAs-mRNAs with a mode of up-down-up (A) or down-up-down (B) and circRNA-miRNAs-mRNAs with a mode of down-up-down (C). KEGG pathway enrichment analysis of lncRNAs-miRNAs-mRNAs with a mode of up-down-up (D) or down-up-down (E) and circRNA-miRNAs-mRNAs with a mode of down-up-down (F) with top 20.
