Figure 1. Identification of DEcircRNAs in HCC. Identification of DEcircRNAs in two GEO datasets using (A) Volcano plot of DEcircRNAs in GSE94508, and (B) Volcano plot of DEcircRNAs in GSE97332. High expression of DEcircRNAs is highlighted in blue, while low expression of DEcircRNAs is highlighted in red; P-value <0.001 (-log10 p-value > 3) and |log2 Fold Change| > 2 were set as thresholds. (C) DEcircRNAs from the two GEO datasets (GSE94508 and GSE97332) analyzed using Venn diagram. (D) 9 downregulated overlapping DEcircRNAs, and 6 upregulated overlapping DEcircRNAs were identified using R language.
