Molecular mechanism of wendan tang in prevention of lipid metabolism disorder in adult rats / 中国中药杂志

ABSTRACT

<p><b>OBJECTIVE</b>To elucidate the molecular mechanism of Wendan Tang in prevention of lipid metabolism disorder in adult rats.</p><p><b>METHOD</b>On the basis of hyperlipidemia rat models, triglycerides (TG), total cholesterol (TC) in serum, activities of lipase (LA), lipoprotein lipase (LPL), hepatic lipase (HL) in liver, parts of hemogram and hepatic LDLR mRNA levels were investigated 21 days after the feeding of atherogenic diet.</p><p><b>RESULT</b>Wendan Tang significantly reduced the serum TG, TC and increased the activity of LPL and LA, but caused no chang in HL. The result of RT-PCR test showed that high fat and high cholesterol feeding could significantly induce the reduction of LDLR mRNA levels, while Wendan Tang could increase hepatic LDLR density.</p><p><b>CONCLUSION</b>Wendan Tang can prevent disorder of lipid metabolism by regulating TC, TG, LDL-c through upregaulation of LDLR transcription level and improving antioxidant ability.</p>
