Effects of Selenium-Enriched Yeast Improved Aflatoxin B1-Induced Changes in Growth Performance, Antioxidation Capacity, IL-2 and IFN- γ Contents, and Gene Expression in Mice.

Effects of Selenium-Enriched Yeast Improved Aflatoxin B1-Induced Changes in Growth Performance, Antioxidation Capacity, IL-2 and IFN-γ Contents, and Gene Expression in Mice. Biol Trace Elem Res. 2018 Dec 15;: Authors: Liu L, Chen F, Qin S, Ma J, Li L, Jin T, Zhao R Abstract Sixty Kunming mice were randomly assigned into three groups. Mice in a control group were fed a basal diet, while mice in AFB1 group and AFB1-Se group were fed the basal diet supplemented with 250 μg/kg AFB1 or the basal diet supplemented with 250 μg/kg AFB1 and 0.2 mg/kg selenium as selenium-enriched yeast, respectively. On day 30 of the experiment, growth performance, glutathione peroxidase (GSH-Px) activities, total antioxidant capacity (T-AOC) levels, and malondialdehyde (MDA) contents in liver, interleukin-2 (IL-2), and interferon-γ (IFN-γ) contents in serum, and cytochrome P3a11 (Cyp3a11), IL-2, IFN-γ, and GSH-Px1 mRNA levels in liver were determined. The results showed that final weights, weight gains, T-AOC levels, GSH-Px1, and IFN-γ mRNA levels in AFB1-Se group and control group were higher or significantly higher than those in AFB1 group (P < 0.05 or P < 0.01), respectively. Body length gains in AFB1 group were lower than those in the control group (P < 0.05), while there was no significant difference between the AFB1-Se and control groups (P > 0.05). IL-2 contents and liver IL-2 mRNA levels in AFB1-Se group were sig...
