Abstract

Abstract: An imbalance of energy intake and expenditure leads to fat accumulation and metabolic disorders. The aim of the study was to investigate the effects of antroquinonol on diet-induced obesity. Thirty-two rats were divided into a control group (C), an obesogenic group (OB), and two experimental groups consuming 25 (OB-AQ25) and 50 mg/kg (OB-AQ50) antroquinonol (n = 8). After a 12-week experimental period, we collected blood, liver, abdominal fat, and gastrocnemius muscle tissue for analysis. The obesogenic diet induced greater weight gain and fat accumulation, and increased hepatic lipids, and tumor necrosis factor-α and interleukin-1β concentrations in rats. Antroquinonol consumption reduced epididymal and hepatic lipids and inflammatory cytokines. We found that antroquinonol upregulated hepatic adenosine monophosphate-activated protein kinase and downregulated sterol regulatory element-binding protein-1 protein expressions and downregulated fatty acid synthase mRNA expression. In addition, gastrocnemius fibronectin type III domain containing 5 protein expression was also higher in the B group. In conclusion, our results suggested that consuming antroquinonol may ameliorate diet-induced abdominal and hepatic fat accumulation. Practical Application: Antroquinonol is a bioactive compound derived from Antrodia camphorate which is traditionally used in Chinese medicinal cuisine, and is used for developing functional foods in Taiwan. This is the first study investigating the possible effects of antroquinonol on obesity and we found that antroquinonol can ameliorate diet-induced obesity, and therefore may be used in further studies and functional food development.
