We investigated whether the fat and protein fractions of freshwater clam (Corbicula fluminea) extract (FCE) could ameliorate hypercholesterolaemia in rats fed a high-cholesterol diet. We also explored the mechanism and the components that exert the hypocholesterolaemic effect of FCE. The doses of the fat and protein fractions were equivalent to those in 30 % FCE. The fat and protein fractions of FCE, two major components of FCE, significantly reduced the serum and hepatic cholesterol levels. The fat fraction more strongly reduced serum cholesterol levels than the same level of total FCE. The excretion of faecal neutral sterols increased in rats fed the total the FCE and the fat fraction of FCE. On the other hand, faecal bile acid levels were greater in rats fed the total FCE and the fat and protein fractions of FCE than in control animals. The hepatic gene expression of ATP-binding cassette transporter G5 and cholesterol 7α-hydroxylase was up-regulated by the administration of the total FCE and both the fat and protein fractions of FCE. These results showed that the fat and protein fractions of FCE had hypocholesterolaemic properties, and that these effects were greater with the fat fraction than with the protein fraction. The present study indicates that FCE exerts its hypocholesterolaemic effects through at least two different mechanisms, including enhanced excretion of neutral sterols and up-regulated biosynthesis of bile acids.

Lactation induces a variety of morphological and functional changes in the gastrointestinal tract. In the present study we employed tritiated water as the substrate to demonstrate that in the intact rat lactation results in a twofold increase in cholesterol synthesis in the small intestine. Feeding a high-cholesterol diet did not markedly inhibit small intestinal cholesterol synthesis in either control or lactating animals, and the difference in cholesterol synthesis between the two groups persisted. In the large intestine, cholesterol synthesis is increased threefold in the lactating animals, and feeding a high-cholesterol diet did not affect synthesis in either the control or lactating animals. In the liver, lactation stimulated cholesterol synthesis, and quantitatively this increase in hepatic cholesterol synthesis is much greater than the increase observed in the intestines. Feeding the rats a high-cholesterol diet markedly inhibited hepatic cholesterol synthesis in both control and lactating animals, a finding that demonstrates that the feedback inhibition of cholesterol synthesis in the liver is not impaired by lactation. In the lactating animals, the quantity of labeled cholesterol in 1 ml of serum is 2.4 times greater than observed in controls. Feeding the rats a high-cholesterol diet markedly decreased the quantity of labeled cholesterol in the serum in both groups and obliterated the difference between control and lactating animals. This suggests that the increased hepatic cholesterol synthesis in the lactating animals is responsible for the differences in labeled cholesterol in the serum. Cholesterol feeding also reduced the quantity of labeled cholesterol localized to the mammary glands in lactating animals.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract Objectives The objective of this study is to investigate the effects of high hydrostatic pressure (HHP) extract of mulberry fruit on the regulation of hepatic cholesterol metabolism in high-cholesterol diet fed rats. Methods Male Sprague-Dawley rats(6-week-old) were randomly divided into 5 groups, and fed with a normal diet (NOR), High cholesterol diet (HC), HC supplemented with 0.4% mulberry (ML) or 0.8% mulberry (MH) and HC treated with statin (ST) for 4 weeks. Results The HHP extract of mulberry fruit did not affect body weight gain and food intake and reduced the serum and liver lipids in the mulberry supplemented groups (ML, MH). In this study, we found that the HHP extract of mulberry fruit changed the level of genes involved in hepatic cholesterol metabolism. In the MH group, the mRNA levels of apolipoprotein A-1 (apoA-1), ATP-binding cassette transporter A1 (ABCA1) and lecithin-cholesterol acyltransferase (LCAT), which are involved in hepatic HDL biogenesis, were significantly increased by 1.80-, 1.77- and 2.65-fold, respectively, compared with the HC group. The MH group also significantly upregulated mRNA levels of cholesterol efflux related gene such as the liver X receptor α (LXRα), ATP-binding cassette protein G5 (ABCG5) and ATP-binding cassette protein G8 (ABCG8) compared to the HC group in the liver tissue. ABCG5 and ABCG8 expression levels of the MH group were also higher than those of the ST group. The mRNA level of cholesterol 7a-hydroxylase (CYP7A1), which is bile acid synthetic rate-limiting enzyme was higher in the MH group than that of the HC group. Furthermore, the immunohistochemical staining intensity became evident for CYP7A1 in liver of the MH group. Conclusions These results suggest at least partial involvement of HDL cholesterol synthesis, cholesterol efflux and bile acid synthesis in HHP extract of mulberry fruit mediated beneficial effects on hepatic cholesterol metabolism.
