CircRNA expression profile in CRC and control group and screening of differentially-expressed circRNAs.(A) Cluster analysis of the expression of the circRNAs by deep sequencing. The result shows the top 30 differentially-expressed circRNAs. (B) Volcano plot showing fold differences in gene expression. The red dots represent the upregulated or downregulated genes. (C) Cluster analysis of the differentially-expressed circRNAs in the GSE126094 dataset. The result shows the top 30 circRNAs. (D) Venn diagram of the differentially-expressed circRNAs obtained by clustering analysis. The data were analyzed with P-value < 0.05 and LogFC >2 as the threshold. Cluster analysis and Volcano plot analysis were performed using the gplots package in R.
