We examined the effects of S. crispa on serum cholesterol, hepatic enzymes related to cholesterol metabolism, and fecal sterol excretion in rats fed a cholesterol-rich diet for 4 weeks. Male Sprague-Dawley rats (8 weeks old) were randomly divided into 5 groups (n = 6 mice per group): normal diet (normal control [NC]), cholesterol-rich diet (cholesterol control [CC]), cholesterol-rich diet plus S. crispa fruiting body (SC), cholesterol-rich diet plus S. crispa extract (SCE), and cholesterol-rich diet plus S. crispa residue (SCR). SCE supplementation significantly enhanced hepatic cholesterol catabolism through the upregulation of cholesterol 7α-hydroxylase (CYP7A1) messenger RNA (mRNA) expression (2.55-fold compared with that in the NC group; P < 0.05) and the downregulation of 3-hydroxy-3-methylglutaryl coenzyme A (HMG-CoA) reductase mRNA expression (0.57-fold compared with that in the NC group; P < 0.05). Additionally, the SCE diet resulted in the highest fecal excretion of cholesterol and bile acid in hypercholesterolemic rats. In conclusion, mRNA expression of CYP7A1 and HMG-CoA reductase were significantly modulated by the absorption of SCE samples. Also, SCE samples had a significant effect on fecal bile acid and cholesterol excretion. These results suggest that SCE samples can induce hypocholesterolic effects through cholesterol metabolism and the reduction of circulating cholesterol levels. %8 2016-01-07
