The hippocampus of rats with chronic gulf war illness-like symptoms (GWI-rats) showed a higher expression of multiple antioxidant genes. (A) Cluster diagram comparing the relative expression of antioxidant genes between animals exposed to vehicle (n = 5), GWI-related chemicals (GWIR-Cs), and stress (n = 5), which was measured 6 months after exposure using quantitative real-time polymerase chain reaction. Bar charts comparing the expression of Apc, Gsr, Gstk1, Gstp1, Prdx5, Ptgs1, and Srxn1, between the vehicle and GWI groups are illustrated in B1–B7. The bar charts comparing the expression of Cat, Ctsb, Gpx3-4, Gpx6-7, Prdx1-2, Prdx6, Txnrd1, and Txnrd2, between the vehicle and GWI groups are illustrated in Figure 1. p < 0.05; ∗∗p < 0.01; ∗∗∗p < 0.001.
