Antioxidant capacity in BRL cells treated with different concentrations (ranging from 0.1 to 48 μM) of SeNPs for 24 h. Data are presented as the mean ± SD, n = 5. Control means the control treatment (the complete medium with 0 μM SeNPs). ^∗, ^∗∗, and ^∗∗∗ indicate significant difference as compared with the control (P < 0.05, 0.01, and 0.001 respectively). GSH-Px: glutathione peroxidase; CAT: catalase; MDA: malondialdehyde; SOD: superoxide dismutase; T-AOC: total antioxidation capability.
