PPI network analysis and hub gene selection. (a) PPI network of the DEGs. Blue circles and red diamonds represent downregulated genes and upregulated genes, respectively; the size of circles or diamonds indicates values, with larger circles or diamonds representing smaller values. (b) Venn diagram of gene sets ranking top ten based on nine topological analysis algorithms in cytoHubba plugin. The intersection of the top gene sets revealed four hub genes. PPI: protein-protein interaction.
