The antioxidative effects of the bioactive compounds enriched sesame oil (e.g. lignans and tocopherols) are well established. This study aims to elucidate whether sesame oil could reduce renal oxidative stress induced by a high fat diet (HFD). Mice received HFD for 12 weeks (n=7 per group), which was prepared by adding 20% (w/w) lard (lard group) or sesame oil (sesame group) to the chow diet, respectively. Compared with mice in the lard group, renal lipid levels of those in the sesame group were reduced, shown by decreases in protein expression of transcription factors and enzymes involved in fatty acid synthesis (sterol regulatory element-binding protein-1 and acetyl coenzyme A carboxylase α) and an increase in -oxidation (peroxisome proliferator-activated receptor α and carnitine palmitoyltransferase I) (P<0.05). In the sesame group, levels of peroxynitrite and thiobarbituric acid reactive substances were also reduced, whereas the level of glutathione was increased. In addition, there was elevated protein expression levels of antioxidant enzymes regulated by nuclear factor-like 2, such as superoxide dismutase, glutathione peroxidase, and glutathione S-transferase (P<0.05), and decreased expression for nuclear factor kappa B and cyclooxygenase 2 (P<0.05). These results suggest that sesame oil could ameliorate HFD-induced renal damage by suppressing oxidative stress and inflammation.
