title: Intake of mulberry 1-deoxynojirimycin prevents diet-induced obesity through increases in adiponectin in mice.
abstract: In this study, the anti-obesity effect of 1-deoxynojirimycin (DNJ) was examined in the diet-induced obese mouse model. Mulberry DNJ was administered to the obese mice for 12 weeks. As a result, DNJ decreased both the visceral fat weight and adipocyte size. To determine the influence of DNJ on lipid metabolism, lipid parameters of the plasma and the liver and the activities of several molecules related to lipid metabolism in the liver were measured. DNJ activated the β-oxidation system, suppressed lipid accumulation in the liver and reduced plasma triacylglycerol. Since it was thought that the factor activated in the β-oxidation system was adiponectin, plasma adiponectin levels were measured and it was shown that plasma adiponectin was increased with DNJ. Therefore, it was suggested that DNJ promoted an increase in plasma adiponectin and activated the β-oxidation system. Overall, it was shown that DNJ prevents diet-induced obesity through an increase in adiponectin.
