Figure 2: (a) Volcano plot showing the relative expression of miRNA genes form a one-class -test. The vertical lines correspond to 2.0-fold up and down, respectively, and the horizontal line represents a value of 0.05. The red point in the plot represents the differentially expressed genes with statistical significance. (b) Hierarchical clustering for differentially expressed miRNAs in cancer versus normal pass volcano plot (fold change ≥2.0). Red indicates high relative expression, and green indicates low relative expression.
