Figure 1. Identification of potential circRNAs in colorectal cancer. (A) The volcano plot of differentially expressed circRNAs (DECs) in colorectal cancer from GSE126094 dataset. The red dots and green dots represent upregulated DECs and downregulated DECs with significance (adjusted P-value < 0.05 and |log2FC| > 1), respectively. The black dots are those DECs without significance. (B) The heatmap of 10 potential DECs (|log2FC| > 4).
