A PPI network of DEGs was analyzed using Cytoscape software. The size and color of the nodes corresponding to each gene were determined according to the degree of interaction. The size of the nodes reflects the degree value, where the larger the node, the greater the degree value. The closer to the blue node, the higher connectivity between two nodes. B PPI network for the top ten hub genes. C and D Graphic representation of top two significant modules of the PPI network. (C Module 1, D Module 2)Back to article page
