Hierarchical clustering of genes that were differentially expressed in the Tg vs. wt hippocampi during the “aging stage” (9, 14.5, and 20 month old). The clusters are further subdivided into differing gene expression patterns across age of both Tg and wt mice. A further subdivision of the clusters was made based on whether the gene expression levels for the Tg hippocampi were higher at 9 months than those for the wt (see text for full description).
