Obesity is associated with metabolic disorders. Sulforaphane, an isothiocyanate, inhibits adipogenesis and the occurrence of cardiovascular disease. In this study, we investigated whether sulforaphane could prevent high-fat diet (HFD)-induced obesity in C57BL/6N mice. Mice were fed a normal diet (ND), HFD or HFD plus 0.1% sulforaphane (SFN) for 6 weeks. Food efficiency ratios and body weight were lower in HFD-SFN-fed mice than in HFD-fed mice. SFN attenuated HFD-induced visceral adiposity, adipocyte hypertrophy and fat accumulation in the liver. Serum total cholesterol and leptin, and liver triglyceride levels were lower in HFD-SFN-fed mice than in HFD-fed mice. SFN decreased the expression of peroxisome proliferator-activated receptor gamma (PPAR-gamma), CCAAT/enhancer-binding protein alpha (C/EBP alpha) and leptin in the adipose tissue of HFD-SFN mice and increased adiponectin expression. Phosphorylation of AMP-activated protein kinase alpha (AMPK alpha) and acetyl-CoA carboxylase in the adipose tissue of HFD-SFN-fed mice was elevated, and HMG-CoA reductase expression was decreased compared with HFD-fed mice. Thus, these results suggest that SFN may induce antiobesity activity by inhibiting adipogenesis through down-regulation of PPAR gamma and C/EBP alpha and by suppressing lipogenesis through activation of the AMPK pathway.
