An inverse correlation between gene expression changes and IR changes. Graphs depict log₂ expression changes between pairs of samples for all genes with measured IR ratios (center panels), genes with IR ratios only increasing greater than or equal to twofold (left panels), and genes with IR ratios only decreasing greater than or equal to twofold (right panels). Pairwise comparisons of samples are indicated to the left. Median log₂ expression changes are indicated within each graph.
