Intracellular and extracellular cholesterol levels are tightly maintained within a narrow concentration range by an intricate transcriptional control mechanism. Excess cholesterol can be converted into oxysterols, signaling molecules, which modulate the ac ...
Statins are hypolipidemic drugs which not only improve cholesterol but also triglyceride levels. Whereas their cholesterol-reducing effect involves inhibition of de novo biosynthesis of cellular cholesterol through competitive inhibition of its rate-limiti ...
Liver X receptors (LXRs) are nuclear receptors that act as metabolic sensors for cellular cholesterol (Xol) and oxysterol content. Increased oxysterol levels activate LXRs, which then induce: the removal of cholesterol out of peripheral cells; transport of ...
The peroxisome proliferator-activated receptor-alpha (PPARalpha) controls gene expression in response to a diverse class of compounds collectively referred to as peroxisome proliferators. Whereas most known peroxisome proliferators are of exogenous origin ...
The hypolipidemic fibrates and antidiabetic thiazolidinediones display potent triglyceride-lowering activities. Studies on the molecular action mechanisms of these compounds indicate that thiazolidinediones and fibrates exert their action by activating dis ...
Compounds which are PPAR delta agonists are described. These compounds are useful for raising high density lipoprotein (HDL) plasma levels in mammals and for preventing, halting or slowing the progression of atherosclerotic cardiovascular diseases and rela ...
The major components of soybean flour (ie, proteins, fibres, and isoflavones) have been investigated as possibly responsible for the cholesterol-lowering effects of soy-based diets. The evidence for and against the involvement of each component is reviewed ...
Overexpression of the adipocyte differentiation and determination factor-1 (ADD-1) or sterol regulatory element binding protein-1 (SREBP-1) induces the expression of numerous genes involved in lipid metabolism, including lipoprotein lipase (LPL). Therefore ...
Intracellular fatty acid (FA) concentrations are in part determined by a regulated import/export system that is controlled by two key proteins, i.e. fatty acid transport protein (FATP) and acyl-CoA synthetase (ACS), which respectively facilitate the transp ...
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 ...
