In the liver, BD exposure significantly increased SOD and CAT activities (F(3.20) = 3.2 and 3.9, p < 0.05 to SOD and CAT, respectively) and decreased GPx activity (F(3.20) = 3.8, p < 0.05) leading to protein (F(3.20) = 4.3, p < 0.05) and lipid oxidation (F(3.20) = 10.29, p < 0.001). The gene discussed is SOD1; the disease is Behcet disease.
