Hierarchical cluster of 25 probesets with relatively high expression in NOD and low expression in C57BL/6 mice. The 14 probesets with significant differences between the strains (P < 0.001) are marked by black bars on the right side of the figure. The intensity of the node color indicates the degree of increase (red) or decrease (blue) of the gene expression signal relative to the mean signal intensity.
