Subtype-specific association networks between DNA methylation and gene expression, and Venn diagram for the number of edges in the network. An edge in a subtype-specific association network is drawn if methylation node A and gene expression node B have non-zero a regression coefficient resulted from kernel weighted lasso. The edges are colored based on their subtype-specific association. Venn diagram represents the number of edges occurring in each association network where intersection region stands for the number of edges appearing in more than two networks
