CD36 deficiency rescues lipotoxic cardiomyopathy.
Obesity-related diabetes mellitus leads to increased myocardial uptake of fatty acids (FAs), resulting in a form of cardiac dysfunction referred to as lipotoxic cardiomyopathy. We have shown previously that chronic activation of the FA-activated nuclear receptor, peroxisome proliferator-activated receptor alpha (PPARalpha), is sufficient to drive the metabolic and functional abnormalities of th...
متن کاملA novel mouse model of lipotoxic cardiomyopathy.
Inherited and acquired cardiomyopathies are associated with marked intracellular lipid accumulation in the heart. To test the hypothesis that mismatch between myocardial fatty acid uptake and utilization leads to the accumulation of cardiotoxic lipid species, and to establish a mouse model of metabolic cardiomyopathy, we generated transgenic mouse lines that overexpress long-chain acyl-CoA synt...
متن کاملMacrophages modulate cardiac function in lipotoxic cardiomyopathy.
Diabetes is associated with myocardial lipid accumulation and an increased risk of heart failure. Although cardiac myocyte lipid overload is thought to contribute to the pathogenesis of cardiomyopathy in the setting of diabetes, the mechanism(s) through which this occurs is not well understood. Increasingly, inflammation has been recognized as a key pathogenic feature of lipid excess and diabet...
متن کاملCeramide is a cardiotoxin in lipotoxic cardiomyopathy.
Ceramide is among a number of potential lipotoxic molecules that are thought to modulate cellular energy metabolism. The heart is one of the tissues thought to become dysfunctional due to excess lipid accumulation. Dilated lipotoxic cardiomyopathy, thought to be the result of diabetes and severe obesity, has been modeled in several genetically altered mice, including animals with cardiac-specif...
متن کاملThe association between small dense low density lipoprotein,apolipoprotein B, apolipoprotein B/apolipoprotein A1 ratio and coronary artery stenosis
Abstract Background: Recently, small dense low density lipoprotein (sdLDL) has been highlighted as a new risk factor for the coronary artery disease (CAD).Small dense LDLs are believed to be atherogenic since these particles are taken up more easily by arterial wall. They are readily oxidized and have reduced affinity for low density lipoprotein (LDL) receptor and increased affinity...
