In vivo EGFR-associated profiles and additional genes implicated in the EGFR-RAS-MEK pathway. A) The top 500 induced genes from the SUM102 post treatment experiments were hierarchical clustered using the 248 UNC tumors. Colored bars indicate the location of the three clusters in D-E. B) Tumor associated dendrogram color coded according to tumor subtype: Luminal A – dark blue, Luminal B – light blue, true normals and normal-like – green, HER2+/ER-negative – pink, and basal-like – red. C) Cluster #1 that identified a mixed group of tumors. D) Selected genes from the center of Cluster #2 that are high in most basal-like tumors. E) Selected genes from the center of Cluster #3 that are high in the luminal tumors. F) Data for genes with suggested roles in EGFR-pathway. G) Data for the KRAS-amplicon signature identified in Herschkowitz et al. .
