A 6-Gene Risk Signature Predicts Survival of Glioblastoma Multiforme

Figure 1

Differentially expressed genes (DEGs) and bidirectional hierarchical clustering. (a) Scatter plot showing gene expression levels. Upregulated and downregulated DEGs are shown as red and green dots, respectively. Genes with no obvious changes in expression level are shown as blue dots. (b) Bidirectional hierarchical clustering of samples based on the expression level of DEGs. Tumor and normal samples are represented as dark and white bar, respectively. Upregulated and downregulated DEGs are shown in red and blue, respectively.
