Cumulative distribution plots. Plotted is the normalized t-statistics for differential expression on the x-axis plotted against the fraction of the gene set that has that x-value or lower on the y-axis. Gene sets that are shifted away from the plot of the entire data set are considered to be significant. (A) Genes involved in TGFβ signaling are down regulated in both species. (B) Genes involved in cholesterol biosynthesis are up regulated in both species.
