Differential expression analysis. (A) Volcano plot of differentially expressed microRNAs in the GSE64989 dataset. (B) Volcano plot of differentially expressed microRNAs in the TCGA hepatocellular carcinoma dataset. Red indicates up-regulated, blue indicates down-regulated, and gray indicates not significantly different. (C) Overlap of up-regulated miRNAs and down-regulated miRNAs in the two comparison-pairs (see Methods) were visualized on the Venn diagram. miRNA, microRNA.
