The hypothesis of this study was that peanut sprout extracts (PSE) could reduce fat accumulation through activating the transcription of SREBP-1c genes. Sprague-Dawley (SD) were randomly assigned into two groups and fed the following diet for 4 weeks; 10 normal fat (NF, 7 g of fat/100 g diet) and 30 high fat (HF, 20 g of fat/100 g diet). After 4 weeks, the HF group was divided into three groups; HF, HF with 15 mg of PSE/kg diet (HF+low PSE, 0.025% resveratrol), and HF with 30 mg of PSE/kg diet (HF+high PSE, 0.05% resveratrol) and fed for an additional 5weeks. The HF+high PSE group had significantly lower weight gain than the HF group. Plasma triglyceride (TG) level and the hepatic total lipid level were significantly lower in the HF+high PSE group compared to the HF group. Fecal excretions of total lipids, cholesterol, and TG in the HF+high PSE group tended to be higher than in the HF group, but these differences were not significant. The mRNA expressions of fatty acid synthase, glucose-6-phosphate dehydrogenase, and sterol regulatory element binding protein-c (SREBP-1c) were significantly lower in the HF+high PSE group than in the HF group.The mRNA expressions of hydroxy-3-methylglutaryl coenzyme A reductase and acyl-CoA cholesterol acyltransferase were significantly lower in the HF+high PSE groups compared to the HF group. The mRNA expression of cholesterol 7α-hydroxylase1 was significantly higher than the HF group in both the HF+low PSE and HF+high PSE groups, with much greater increase observed in the HF+high PSE group. In conclusion, consumption of PSE was effective for improving blood lipid levels, possibly by suppressing the expression of SREBP-1c, in rats fed a high-fat diet.
