Apolipoprotein CIII Links Dyslipidemia with Atherosclerosis

Apolipoprotein CIII links hyperlipidemia with vascular endothelial cell dysfunction.

BACKGROUND Apolipoprotein CIII (apoCIII) is a component of some triglyceride-rich very-low-density and low-density lipoprotein and is elevated in dyslipidemia with insulin resistance and the metabolic syndrome. We previously reported that apoCIII directly activates proinflammatory and atherogenic signaling in vascular endothelial cells through protein kinase C-beta (PKCbeta). Because PKCbeta im...

Apolipoprotein E in Diabetic Dyslipidemia and Atherosclerosis

Apolipoprotein CIII and atherosclerosis: beyond effects on lipid metabolism.

The prevailing concept of mechanisms responsible for the development of atherosclerotic lesions largely focuses on the accumulation and retention of low-density lipoproteins in the arterial intima and their subsequent oxidative modification. This oxidation leads to activation of the endothelium, and particularly, expression of adhesion molecules that mediate leukocyte adherence and chemokines w...

Apolipoprotein E recycling: implications for dyslipidemia and atherosclerosis.

After receptor-mediated endocytosis, the intracellular fate of triglyceride-rich lipoproteins (TRLs) is far more complex than the classical degradation pathway of low-density lipoproteins. Once internalized, TRLs disintegrate in peripheral endosomes, followed by a differential sorting of TRL components. Although core lipids and apolipoprotein B are targeted to lysosomes, the majority of TRL-der...

Transcriptional activation of apolipoprotein CIII expression by glucose may contribute to diabetic dyslipidemia.

OBJECTIVE Hypertriglyceridemia and fatty liver are common in patients with type 2 diabetes, but the factors connecting alterations in glucose metabolism with plasma and liver lipid metabolism remain unclear. Apolipoprotein CIII (apoCIII), a regulator of hepatic and plasma triglyceride metabolism, is elevated in type 2 diabetes. In this study, we analyzed whether apoCIII is affected by altered g...
