Figure 4

Two dimensional hierarchical clustering of genes that exhibited altered expression in liver samples from ad libitum (AL) fed or fasted rats. Genes that were significantly changed by overnight fasting were identified using either (A) EPIG (n = 190 genes) or (B) t-test (n = 311 genes) analysis of data from 115 cel files and 5 sites. Gene expression levels were normalized to the average AL fed value and color-coded on a fold change scale of 6.4 to -9.5 (red to green), using default contrast settings in TreeView [32].
