Venn diagram displaying differentially expressed probe sets that intersect or non-intersect between different comparison groups. Applying a FDR p-value < 0.05 and FC > 2.0 resulted in 370 differentially expressed probe sets that intersect between the two comparison groups BCBM vs. BC and BCBM vs. prBT (Additional file 1). The 370 probe sets include a number of annotated genes, which are represented by two or more probe sets. Numbers of probe sets that are differentially expressed in each comparison group are given in parentheses
