Hierarchical representation of self-organizing maps (SOM) clustered samples based on the expression profiles of biologically meaningful modules. The clustering of PCM and MM samples was based on similarities in the expression profiles of 44 non-redundant genes that contributed most significantly (cut off set as 10-3.3) to the change in the status of all 22 modules identified in this study. The SOM heatmap shows PCM samples by green bars and MM samples by red bars. Red: higher expression in the tumor than the reference mRNA; green: lower expression than the reference; black: no change compared to the reference.
