Figure 6.

Significant pathways involving differential genes by path-net construction. The Path-Net depicted the interactions between the significant pathways of the differentially expressed genes, and was built according to the interactions with pathways in the KEGG database directly and systemically. Cycle nodes represent pathways, the size of nodes represents the power of the interrelation among the pathways, and an arrow between two nodes represents an interaction target between pathways. The more edges of a pathway, the more pathways connecting to it, and the more central role it has within the network.
