Figure 2.

Heat map using ANOVA identifies probesets/genes different among the three molecular groups. There are actually two different expression groups within subgroup 3—one called subgroup 3 while the other called minor subgroup 3. These three subgroups correlate partially with histology but did not correlate with the run date and therefore not accounted by any batch effect. Mitotic spindle assembly checkpoint (MSAC) genes are differentially expressed with highest level of expression in subgroup 3 and minor subgroup 3 while other expression groups have upregulation of specific pathways.
