Visualization of hub genes in the pink module network. All gene-to-gene correlations were selected in the pink module, and the network was visualized by means of the Cytoscape software. Edge (grey) width is proportional to the weight of the correlation between two genes. All large labeled nodes are the identified hubs (gene significance [GS i GS] >0.2 and scaled connectivity [K i ] > 0.3), whereas darkgolden nodes represent hubs that show the strongest correlations with the phenotype (these are “key hub genes”)
