Effects of dietary argan oil and olive oil on mouse liver antioxidant capacities and on their enhancement by LPS. (A) Superoxide dismutase (SOD); (B) catalase (CAT); (C) glutathione peroxidase (GPx) and glutathione (GSH) levels (D) Mice received, for 25 days, a standard chow (control: Ctl); a standard chow supplemented with 6% (w/w) argan oil (AO) or a standard chow supplemented with 6% (w/w) olive oil (OO). Sixteen hours before euthanasia, separate animal groups, given control, AO and OO-supplemented diets, underwent an intraperitoneal injection of 100 μg LPS (LPS, AO + LPS and OO + LPS groups, respectively). All values are means ± SEM (n = 6 per group). Statistical significance of higher mean signal intensity (*** p < 0.001, ** p < 0.01, * p < 0.05) compared to control and (+++
p < 0.001, ++
p < 0.01) compared to LPS.
