This study explored the effects of sesamin on nonalcoholic steatohepatitis (NASH). High-fat and high-fructose diet-fed mice supplemented with or without sesamin. The results suggested that sesamin-treated mice lost body weight and fat tissue weight, had lower levels of serum metabolic parameters, and insulin resistance was mitigated. Histological examinations showed that sesamin treatment mitigated the progression of hepatic steatosis, and inflammation. In addition, sesamin enhanced hepatic antioxidant capacity, and decreased the activations of hepatic c-jun N-terminal kinase, inhibitor of kappa B kinaseα, and insulin receptor substrate 1 as well as hepatic interleukin-6 and tumor necrosis factor-alpha levels. Further experiments indicated that sesamin treatment downregulated GRP78 and phospho-inositol-requiring enzyme 1 (IRE1) expression, and upregulated x-box binding protein 1 (XBP1) expression in hepatic tissue. The aforementioned results suggest that sesamin alleviates obesity-associated NASH, which might be linked to the effect of sesamin on the regulation of the hepatic endoplasmic reticulum stress-IRE1/XBP1 pathway. Thus, sesamin may be a good food functional ingredient in the treatment of obesity-associated NASH.
