Gene co-expression network. Genes from profiles No.9 and No.16 were analyzed and identified by gene co-expression network with k-core algorithm. Cycle nodes represent genes, the size of nodes represents the power of the interrelation among the nodes, and edges between two nodes represent interactions between genes. The more edges of a gene, the more genes connecting to it, the more central role it has within the network.
