This study investigated the possible anti-obesity effects of Hypsizigus marmoreus on high fat-fed mice. Thirty male C57BL/6 mice were randomly divided into 3 groups: a normal diet group (N), a high-fat diet group (HF), and a high-fat diet with 5% Hypsizigus marmoreus group (HF-H). After 8 weeks, the body weights in the HF group significantly increased, while those of the HF-H group decreased. Also, liver and adipose tissue weights in the HF-H group significantly decreased. Total serum cholesterol, leptin, and insulin levels were significantly higher in the HF group than those of the N group, but lower than those of the HF-H group. Accumulation of hepatic lipids was apparent in the HF group, as indicated by HE staining and hepatic lipid analysis, while these effects were improved by supplements with Hypsizigus marmoreus in the HF-H group. Also, a reduction in adipocyte size of the epididymal adipose tissue was observed in the HF-H group. PPARγ, SREBP-1c, and SCD-1 protein expressions were down-regulated in the epididymal adipose tissue of the HF-F group compared to the HF group. Taken together, these results suggest that Hypsizigus marmoreus may an effective anti-obesity treatment.
