The results of submodule anlysis of PPI network. a The sub-network of module a; b The sub-network of module b; c The sub-network of module c; d The sub-network of module d. Node represents genes and edge connects the nodes to indicate interactions among them. The red circle node represents up-regulated genes, while the green rhombus node stands for down-regulated genes. The node size represents connectivity degree. PPI: protein–protein interaction
