Abstract

© 2017 Elsevier Inc. Inflammation is a major underlying cause for obesity-associated metabolic diseases. Hence, anti-inflammatory dietary components may improve obesity-related disorders. We hypothesized that delta-tocotrienol (δT3), a member of the vitamin E family, reduces adiposity, insulin resistance and hepatic triglycerides through its anti-inflammatory properties. To test this hypothesis, C57BL/6J male mice were fed a high-fat diet (HF) with or without supplementation of δT3 (HF+δT3) at 400 mg/kg and 1600 mg/kg for 14 weeks, and they were compared to mice fed a low-fat diet (LF) or HF supplemented with metformin as an antidiabetic control. Glucose tolerance tests were administered 2 weeks prior to the end of treatments. Histology, quantitative polymerase chain reaction and protein analyses were performed to assess inflammation and fatty acid metabolism in adipose and liver tissues. Significant improvements in glucose tolerance, and reduced hepatic steatosis and serum triglyceri
