Visualization of the compromise. Each point represents one of the 2,276 genes, i.e., observations, projected on the first and second principal component. Red (repression) and blue (induction) color corresponds to the direction average fold-change of expression levels (main panel); the color intensity correspond to the magnitude of change. Genes that exhibit a significant contribution, as determined by bootstrapping procedures, are colored in dark, non-significantly contribution genes in light gray (lower panel).
