Number of genes in the liver that are affected by fasting. A) Number of differentially expressed genes (≥ 1.4-fold change in expression; P < 0.01) at each time point studied. The left-sided Venn diagram shows the number of up-regulated and the right-sided diagram the number of down-regulated genes. Genes that were changed in expression at more than one time point are shown in the overlapping areas. B) Supervised hierarchical cluster based on correlation and complete linkage.
