Figure 3: Pathnet analysis of differential methylation genes in low level benzene-exposed workers. Nodes represent pathways. The area of nodes displays the degree which is the number of other pathways that interact with this pathway. Lines indicate interactions between pathways, where pathways indicated by the arrow head are regulated by pathways of the arrow tail. Red denotes the hypermethylated pahtway. Blue denotes the hypomethylated pahtway. Yellow denotes the hypermethylated and hypomethylated pahtway.
