Production of apolipoprotein E-rich LDL by the liver. The effect of dietary cholesterol and some lipid lowering agents

Abstract

We reported previously that cholesterol feeding induced an increase in hepatic secretion of VLDL and a decrease in that of LDL, especially LDL-apo B100, using monkey liver perfusion. In the present study we conducted rat liver perfusion using the HMG Co A reductase inhibitor (CS-514) and Kampo medicine (Daisaikoto) to elucidate the mechanism of the effect of dietary cholesterol on hepatic lipoprotein and apolipoprotein synthesis. Although the secretion of VLDL was increased by cholesterol feeding, that of LDL and especially of apo B100 of LDL were markedly decreased, and apo E of the LDL was increased as observed in the monkey liver perfusion experiments. The effect of CS-514 was clearly different from the effect of dietary cholesterol in spite of the suppression of hepatic cholesterogenesis which was comparable to that induced by cholesterol feeding, suggesting that the decrease in secretion of LDL-apo B100 induced by the dietary cholesterol is not due to suppressed cholesterogenesis. Daisaikoto, which was added to the diet together with cholesterol, diminished the effects of dietary cholesterol on the plasma and hepatic cholesterol levels. When the liver treated with Daisaikoto was perfused, the effect of dietary cholesterol ...Continue Reading

ApoE, Lipids & Cholesterol

Serum cholesterol, triglycerides, apolipoprotein B (APOB)-containing lipoproteins (very low-density lipoprotein (VLDL), immediate-density lipoprotein (IDL), and low-density lipoprotein (LDL), lipoprotein A (LPA)) and the total cholesterol/high-density lipoprotein (HDL) cholesterol ratio are all connected in diseases. Here is the latest research.

ApoE Phenotypes

Apolipoprotein E (APOE) is a protein involved in fat metabolism and associated with the pathogenesis of Alzheimer's disease and cardiovascular disease. Here is the latest research on APOE phenotypes.
