Eight key long non-coding RNAs predict hepatitis virus positive hepatocellular carcinoma as prognostic targets

Figure 2 Heat map and volcano plot. A: Heat map demonstrating the differential expression of long non-coding RNAs (lncRNAs). The X-axis represents the samples, while the Y-axis denotes the differentially expressed lncRNAs. Green color is indicative of the down-regulated genes, while the red color stands for the up-regulated genes; B: Volcano plot showing the differential expression of lncRNAs. The X-axis indicates the false discovery rate values after log transformation, whereas the Y-axis suggests the log₂ (fold change) values for lncRNA expression. FDR: False discovery rate; FC: Fold change.
