Most cells acquire cholesterol by endocytosis of circulating low-density lipoproteins (LDLs). After cholesteryl ester de-esterification in endosomes, free cholesterol is redistributed to intracellular membranes via unclear mechanisms. Our previous work sug ...
The deacetylase sirtuin 1 (Sirt1) exerts beneficial effects on lipid metabolism, but its roles in plasma LDL-cholesterol regulation and atherosclerosis are controversial. Thus, we applied the pharmacological Sirt1 activator SRT3025 in a mouse model of athe ...
Peroxisome proliferator-activated receptor-gamma (PPARgamma) plays a role in adipocyte differentiation and insulin sensitization. We identified and characterized a new C/T substitution at position -689 (-689C>T) in the P2 promoter of PPARgamma in a putativ ...
There are many elements in plasma that can act as surrogate markers of the physiological well-being of a mouse, thus making the collection of blood and plasma a general technique with many applications in mouse phenotyping. For example, the presence of cer ...
Postprandial inflammation is an important factor for human health since chronic low-grade inflammation is associated with chronic diseases. Dairy products have a weak but significant anti-inflammatory effect on postprandial inflammation. The objective of t ...
In this work we introduce and discuss several mathematical models, based on partial differential equations, devised to study the coupled transport of macromolecules as low-density lipoproteins in the blood stream and in the arterial walls. These models are ...
The development of a new assay for lipoproteins by capillary electrophoresis in fused-silica capillaries and in glass microdevices is described in this paper. The separation of low-density (LDL) and high-density (HDL) lipoproteins by capillary zone electro ...
Atherosclerosis is a disease characterized by lipid accumulation in the vascular wall leading to myocardial infarction or stroke. Hypercholesterolemia is an important risk factor and current treatments are largely based on cholesterol lowering. In spite of ...
The cholesteryl ester transfer protein (CETP) enables the transfer of cholesteryl ester (CE) from high density lipoproteins (HDL) to low-density lipoproteins (LDL) in the plasma compartment. CETP inhibition raises plasma levels of HDL cholesterol; a ternar ...
Current treatment for atherosclerotic heart disease consists mainly of the administration of 3-hydroxy-3-methylglutaryl-coenzyme A (HMG-CoA) reductase inhibitors or 'statin' class of drugs. Statins, which lower low-density lipoprotein cholesterol levels an ...
