PPI network and hub genes. (a) The whole PPI network of DEGs. Blue nodes denoted upregulated genes, while yellow nodes denoted downregulated genes; the lines represented an interaction relationship between the nodes. (b) The most significant module selected from the PPI network, all genes in this module were downregulated. (c) The top 20 genes evaluated by connectivity degree in the PPI network, the color from red to yellow represented the connectivity degree from high to low.
