FIG. 8.

Regulation of genes relevant to apoptosis and oxidative stress. Lane L4, experimental versus control lungs at day 4; lane L7, experimental versus control lungs at day 7; lane TB4, experimental versus control tracheobronchial lymph nodes at day 4; lane TB7, experimental versus control tracheobronchial lymph nodes at day 7. The genes in this bioset [differentially regulated by 1.5-fold or more in at least two experiments (P ≤ 0.05)] were clustered according to a hierarchical algorithm; green bars represent genes that were repressed by the experiment, and darker colors represent lesser differential expression.
