The ceRNA regulatory network of circRNA-miRNA-mRNA in breast cancer. (A) Volcano plot of differentially expressed genes between breast cancer and normal breast tissues in TCGA. (B) Venn diagram indicating 161 overlapping differentially expressed genes determined from TCGA in breast cancer and the predicted target genes. (C) The ceRNA regulatory network of circRNA-miRNA-mRNA in breast cancer. Hexagon represent circRNAs, triangles indicate miRNAs, and ovals indicate miRNAs.
