Figure 5.

EGFR pathway diagram displayed for each breast tumor subtype. The average gene expression value for each gene within each subtype is displayed for the EGFR-pathway and for the three EGFR-activation profiles using the UNC 248 tumor dataset. Eight genes from the middle of each of the three EGFR-activation clusters were used to view expression of the clusters in each of the subtypes. A pink node border identifies the genes that showed statistically significant associations with subtype. *Note: the NKI HER4 data spot was used since HER4 was not present in the UNC data set. A) Luminal A, B) Luminal B, C) HER2+/ER- and D) Basal-like.
