Sorted mRNA expression data of (A) TCGA BRCA and (C) GBM and the counterparts of (B) METABRIC and (D) REMBRANDT. Genes are sorted by their Super Module memberships and retain the same order in TCGA and external data. Samples are sorted by Sample Groups in TCGA data and by molecular subtypes in external data (luminal A, basal-like, HER2-enriched, and luminal B for METABRIC, and proneural, classical, mesenchymal, and neural for REMBRANDT). Sample subtypes are marked on the top row with the following codes: luminal A (red), basal-like (blue), HER2-enriched (green), and luminal B (cyan) for breast cancer, and proneural (cyan), classical (blue), mesenchymal (green), and neural (red) for GBM.
