**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 |log_{2}FC| > 1), respectively. The black dots are those DECs without significance. (**B**) The heatmap of 10 potential DECs (|log_{2}FC| > 4).
