Moderately Decreased Cholesterol Absorption Rates Are Associated With a Large Atheroprotective Effect

Moderately decreased cholesterol absorption rates are associated with a large atheroprotective effect.

OBJECTIVE Human treatment with ezetimibe results in a moderate 50% to 54% decrease in cholesterol absorption and a 15% to 20% decrease in plasma LDL-cholesterol levels; nevertheless, the efficacy of ezetimibe therapy has been recently challenged by the ENHANCE trial. We examined the efficacy of a moderate decrease in cholesterol absorption in preventing atherosclerosis formation in the mouse. ...

Insulin resistance is associated with increased cholesterol synthesis and decreased cholesterol absorption in normoglycemic men.

Type 2 diabetes has been associated with high synthesis and low absorption of cholesterol independent of weight, indicating that insulin resistance may be a link between glucose and cholesterol metabolism. Therefore, we investigated the relationship of serum cholesterol precursors, reflecting cholesterol synthesis, and serum plant sterols and cholestanol, reflecting cholesterol absorption effic...

Cholesterol remnants and triglycerides are associated with decreased myocardial function in patients with type 2 diabetes

BACKGROUND Recently, genetic studies have suggested a causal relationship between cholesterol remnants and ischemic heart disease. We aimed to determine whether cholesterol remnants and its marker, triglyceride levels, are associated with cardiac function as determined by sensitive echocardiographic measures in a population of patients with type 2 diabetes. METHODS Comprehensive echocardiogra...

Reduced cholesterol absorption upon PPARdelta activation coincides with decreased intestinal expression of NPC1L1.

Peroxisome proliferator-activated receptors (PPARs) control the transcription of genes involved in lipid metabolism. Activation of PPARdelta may have antiatherogenic effects through the increase of plasma HDL, theoretically promoting reverse cholesterol transport from peripheral tissues toward the liver for removal via bile and feces. Effects of PPARdelta activation by GW610742 were evaluated i...
