FXRandLXRRegulationofCholesterolMetabolism

Cholesterol is essential for life and a key in the development of heart disease. Cholesterol homeostasis is achieved through regulation of cholesterol uptake, cholesterol biosynthesis, cholesterol conversion to bile acids and excretion of bile acids. Inhibition of cholesterol biosynthesis upregulates LDLR expression and is the mechanism of action of many drugs used to lower plasma LDL to reduce coronary heart disease......阅读全文
