- Red colored genes: up-regulated; yellow colored genes: down-regulated. For each gene, site of expression (i.e., Section) and response type/trend (i.e., Response) are shown. These eight genes are the most representative for acute-phase response (in all three intestine sections), cholesterol-related processes (i.e., cholesterol homeostasis, transport and efflux: in proximal and middle section) and negative regulation of caspase (in middle and distal section)
