a) Dendrogram depicting unsupervised clustering of array data for 4 PR-A transgenics and 3 wild-type samples. b) Volcano plot for differentially expressed genes (DEG). DEG appear above the green horizontal line (unpaired t-test, P < 0.01). Genes induced > 2-fold are on the right of the right green vertical line (red colored), and the ones repressed > 2-fold are on the left of the left green vertical line (blue colored). c) Heat map depicting the relative fold change in expression levels of the 401 transcripts that were differentially expressed by ≥2.0-fold (P < 0.01, 255 downregulated, blue and 92 upregulated, red) between the PRA transgenic and the wild-type group
