Expression of gene related to antioxidants: (a) SOD; (b) Nrf2; (c) KEAP-1; (d) HO-1. SOD: superoxide dismutase; Nrf2: nuclear factor, erythroid 2-related factor 2; KEAP-1: Kelch-like ECH-associated protein-1; HO-1: heme oxygenase 1. Statistical significance: ^#, ^##, ^###, and ^####, contrasted to the control group; , , , and , contrasted to the t-BHP-treated group.
