ABSTRACT
Aim To establish the hyperlipidemic model and ex-plore the mechanism of hypercholesterolemia in hamster. Meth-ods Hamsters were randomly divided into the control and model groups. The hamsters in the control group were fed with the standard chow and the model group were fed with the high fat di-et. Serum lipids and CYP7A1 activity were detected by enzymat-ic method. The molecular mechanism of cholesterol metabolism was investigated by real-time PCR. Results In comparison with the control group, the concentrations of serum TC, LDL-C, TG and hepatic TC, TG were significantly increased in the model group. The mechanism research showed that in hamsters fed with the high fat diet, the CYP7A1 activity and the mRNA expres-sions of hepatic LDL-R, SREBP-2, CYP7A1, LXRαwere down-regulated, the expression of hepatic FXR was up-regulated. Conclusion The hyperlipidemic model could be developed in hamsters fed with the high fat diet for 4 weeks. LDL-R, SREBP-2, CYP7A1, FXR and LXRαare the biomarkers of hypercholes-terolemia, and also the targets of hypolipidemic drugs.
