dc.description.abstract | Our previous study showed that n-3 polyunsaturated fatty acid (PUFA) and estrogen (E) had synergistic hypocholesterolemic effects by inhibiting cholesterol synthesis and enhancing bile acid synthesis. The purpose of the present study was to investigate the hypothesis that α-linolenic acid (ALA), eicosapentaenoic acid (EPA), and docosahexaenoic acid (DHA) decrease low-density lipoprotein cholesterol (LDL-C), synergistically with E, via hepatic cholesterol synthesis and clearance. Rats were fed a diet with either 0% n-3 PUFA or 1% ALA, EPA, or DHA, relative to total energy consumption, for the entire 12-week study. After ovariectomy, rats were injected with either corn oil or E every 4 days for the last 3 weeks of the study. In combination with E, dietary supplementation with EPA or DHA increased the phosphorylated adenosine monophosphate–activated protein kinase/adenosine monophosphate–activated protein kinase ratio and LDL receptor expression, and it decreased the expression of 3-hydroxy-3-methylglutaryl coenzyme A reductase, sterol regulatory element-binding protein-2, and proprotein convertase subtilisin/kexin type 9 in the liver. In addition, dietary supplementation with EPA or DHA increased hepatic expression of cholesterol 7α-hydroxylase, sterol 12α-hydroxylase, and sterol 27-hydroxylase. However, E decreased the expression of cholesterol 7α-hydroxylase and sterol 12α-hydroxylase and increased the expression of estrogen receptor α and β in the liver. ALA had no significant effects on cholesterol metabolism. In conclusion, the present study suggests that dietary supplementation with EPA and DHA decreased LDL-C synthesis and increased bile acid synthesis and LDL-C clearance by LDL receptor, synergistically with E. | - |
