FIG. 2.

cDNA microarray of selected genes pertaining to interferon pathways and upregulated concurrently with appearance of clinical signs in experimental animals. Lane L4, experimental versus control lungs at day 4; lane L7, experimental versus control lungs at day 7. Genes in this bioset were extracted from the cluster in appendix A, i.e., they were differentially regulated by 1.5-fold or more in at least two experiments (P ≤ 0.05) and were clustered according to a hierarchical algorithm. Red bars represent genes that were induced by the experiment; green bars represent genes that were repressed by the experiment; and darker colors represent lesser differential expression.
