Altered KEGG pathways in breast cancers. In the bar-plot depicting the proportion of cancer samples with altered pathways (19 pathways are listed in the x-axis) the y-axis represents the percentage of samples altered in a given pathway stratified by subtype (red for basal, purple for ERBB2, blue for luminal A, cyan for luminal B, and green for normal-like). The analysis was done in 602 samples from different studies in which the molecular subtype (using PAM50) was available (466 from ref. 1, 98 from ref. 2, 38 from ref. 3).
