Cluster analysis of differentially expressed genes. The 2016 genes differentially expressed in one or both treatment groups vs. fed controls were subjected to hierarchical clustering to visualize similarities and differences between treatment groups. (A). Hierarchical cluster analysis of the 2016 genes (FDR adjusted p-value <0.05) that were differentially expressed between insulin-neutralized vs. fed and/or fasted vs. fed states. (B) Seven clusters (numbers) representing the most distinct effects of treatment were selected to further analyze expression profiles across treatments. Sample ID number on the X-axis corresponds to treatment group: sample 1–5, fasted; 6–10, insulin neutralized; 11–15,fed control. Y-axis represents relative gene expression value.
