Genes in module 1 (blue, 325 genes in total) were mainly associated with ribosome, peroxisome, and PPAR signaling pathway, module 2 (brown, 101 genes in total) dealt with Toll-like receptor signaling pathway, salmonella infection, and phagosome, while module 5 (yellow, 103 genes in total) consisted of genes concerned with focal adhesion, ECM-receptor interaction, and PI3K-Akt signaling pathway. The gene discussed is PPARA; the disease is Salmonella Infections.
