The γ-tocopherol-supplemented diet (250 mg γ- tocopherol and 45 mg α-tocopherol/kg of diet; catalog no. 103742; modified AIN-93G Purified Rodent Diet with corn oil replacing soybean oil) and the basal control diet without supplementation (45 mg γ-tocopherol and 45 mg α-tocopherol/kg diet; no. 101591) were from Dyets. Corn oil, which was commonly used in rodent diet in the past, was used in this basal diet instead of the more recent formulas with soybean oil that contain high levels of γ-tocopherol.
