Figure 3. Summary of microarray data. Shown is an examination of the microarray databased on the number of genes upregulated, downregulated, or not changed. These gene changes were categorized into major functional groups. Upward arrows indicate numbers of genes that were significantly upregulated; down arrows indicate those that were downregulated; and horizontal bars represent those that were not altered. The recovery column shows how the genes in each category were affected during recovery. Ellipses indicate that these were not the only categories affected.
