Visualization of the protein–protein interaction (PPI) network, the most significant module and hub genes. a PPI network of differential co-expression genes. b The most significant module from PPI network. c Selection of hub genes from PPI network through maximal clique centrality (MCC) algorithm. The turquoise nodes represent the genes. Edges suggest the protein–protein relations. The red nodes represent genes with high MCC values, while the yellow nodes represent genes with low MCC values
