The networks for amygdala (Figure 5A), PFC (Figure 5B) and liver (Figure S2C) are displayed as dendrograms. Results from cell-type enrichment analyses for treatment-responsive modules are displayed in a column adjacent to the dendrogram. The p values from these analyses can be found in Tables S10 and S11 for amygdala and PFC, respectively. The arrows indicate the direction of fold-change induced by the PPAR agonist for the PPAR agonist-regulated genes in that module.
