Analyzing Prognostic Hub Genes in the Microenvironment of Cutaneous Melanoma by Computer Integrated Bioinformatics

Figure 7

PPI network and clustered heatmap of 19 hub genes. (a) The color of the node in the PPI network reflects the log(FC) value of the Z score of gene expression, and the size of node indicates the number of interacting proteins with the designated protein, and the thickness of the edges represents the connectivity degree. (b) A clustered heatmap of Pearson correlation coefficients over 19 hub genes. Highly significant correlations are marked in red, significant ones in white, and low ones in blue.
