Figure 3.

Distribution of gene expression ratios for treated and untreated mice. The distribution of expression ratios for saline- and isoproterenol-treated mice is shown. A shows the mean number of genes, expressed as a percentage of the total number of expressed genes, with a given expression ratio (n = 5). Expression ratios are expressed as the number of standard deviations from the mean. B shows the number of genes that exhibited expression changes greater than 2 SD for zero, one, two, three, four, and five of 5 arrays tested, for vehicle vs. vehicle, ISO vs. vehicle, and AII vs. vehicle.
