Acetyltransferase Downregulation of cholesterol biosynthesis in sitosterolemia diminished activitiesof acetoacetyl-CoA thiolase, 3-hydroxy-3methylglutaryl-CoA synthase http://www.mssc.edu/biology/B305/GTS/ss99/neuro/acetyl.htm
Extractions: Acetyl-CoA C-acetyltransferase 2.3.1.9 By Scott Smith Function Acetyl-CoA C-acetyltransferase is also known as Acetoacetyl-CoA thiolase (1). Acetyl-CoA C-acetyltransferase is involved in a side reaction between Glycolysis and the Krebb Cycle (3). The pyruvate produced from Glycolysis is converted into Acetyl-CoA. The Acetyl-CoA C-acetyltransferase functions, in an equilibrium reaction, to catalyze the conversion of Acetyl-CoA to Acetoacetyl-CoA, which then forms Acetoacetate and Ketone Bodies (3). Acetyl-CoA C-acetyltransferase catalysis the reaction Acetyl-CoA + Acetyl-CoA CoA + Acetoacetyl-CoA (1). The EC (Enzyme Commission) number for Acetyl-CoA C-acetyltransferase is 2.3.1.9. The 2 indicates that the enzyme is in the class of transferases, the 3 further indicates it is an acyltransferase that transfers acyl groups, and the 1 identifies the enzyme specifically as an acyltransferase (2). The 9 signifies it as the specific enzyme Acetyl-CoA C-acetyltransferase (2). Below is a section of the biochemical pathways map that illustrates the catalytic role of Acetyl-CoA C-acetyltransferase in the conversion of Acetyl-CoA to Acetoacetyl-CoA (3).

Olson, Ph.D. Helen Hobbs, M.D. Fibulin-5 is an elastin-binding protein essential for elastic fibre development in vivo Extracellular elastic fibres provide mechanical elasticity to tissues and contribute towards the processes of organ remodelling by affecting cellcell signalling. The formation of elastic fibres requires the assembly and crosslinking of tropoelastin monomers, and organization of the resulting insoluble elastin matrix into functional fibres. The molecules and mechanisms involved in this process are unknown. Fibulin-5 (also known as EVEC/DANCE) is an extracellular matrix protein abundantly expressed in great vessels and cardiac valves during embryogenesis, and in many adult tissues including the aorta, lung, uterus and skin, all of which contain abundant elastic fibres.

Combination therapy with HMG-CoA reductase inhibitors ZETIA, administered in combination with an HMG-CoA reductase inhibitor, is indicated as adjunctive therapy to diet for the reduction of elevated total-C, LDL-C, and Apo B in patients with primary (heterozygous familial and non-familial) hypercholesterolemia. Homozygous Familial Hypercholesterolemia (HoFH) The combination of ZETIA and atorvastatin or simvastatin, is indicated for the reduction of elevated total-C and LDL-C levels in patients with HoFH, as an adjunct to other lipid-lowering treatments (e.g., LDL apheresis) or if such treatments are unavailable. Homozygous Sitosterolemia ZETIA is indicated as adjunctive therapy to diet for the reduction of elevated sitosterol and campesterol levels in patients with homozygous familial sitosterolemia.

Extractions: Please, take our 1 second survey! SEASONAL DEPRESSION MENTAL HEALTH ... WEIGHT LOSS Background Clinical studies have demonstrated that elevated levels of total cholesterol (total-C), low density lipoprotein cholesterol (LDL-C) and apolipoprotein B (Apo B), the major protein constituent of LDL, promote human atherosclerosis. In addition, decreased levels of high density lipoprotein cholesterol (HDL-C) are associated with the development of atherosclerosis. Epidemiologic studies have established that cardiovascular morbidity and mortality vary directly with the level of total-C and LDL-C and inversely with the level of HDL-C. Like LDL, cholesterol-enriched triglyceride-rich lipoproteins, including very-low-density lipoproteins (VLDL), intermediate-density lipoproteins (IDL), and remnants, can also promote atherosclerosis. The independent effect of raising HDL-C or lowering triglycerides (TG) on the risk of coronary and cardiovascular morbidity and mortality has not been determined. ZETIA reduces total-C, LDL-C, Apo B, and TG, and increases HDL-C in patients with hypercholesterolemia. Administration of ZETIA with an HMG-CoA reductase inhibitor is effective in improving serum total-C, LDL-C, Apo B, TG, and HDL-C beyond either treatment alone. The effects of ezetimibe given either alone or in addition to an HMG-CoA reductase inhibitor on cardiovascular morbidity and mortality have not been established.

Extractions: The genes, the researchers report, are essential for efficient secretion of cholesterol into the bile, which is the major route that cholesterol exits the body. The discovery sheds new light on potential therapies that could play an important role in reducing high cholesterol, a major risk factor of atherosclerotic diseases, such as coronary heart disease and stroke. "The disruption of the two genes, Abcg5 and Abcg8, reveals their crucial role in biliary cholesterol secretion," said Dr. Liqing Yu, an instructor in the Eugene McDermott Center for Human Growth and Development and in molecular genetics and lead author of the study. "In humans and mice, the secretion of cholesterol into the bile is essential for maintaining cholesterol homeostasis and constitutes a major defense against the accumulation of dietary cholesterol in blood and tissues."

Extractions: SCRI This document lists topics under the headings - Cholesterol Cholesterol esters Plant sterols and sterol derivatives Cholesterol 3-sulfate Analysis In animal tissues, cholesterol (cholest-5-en-3ß-ol) is by far the most abundant member of a family of polycyclic compounds known as sterols . It can also be described as a polyisoprenoid. Cholesterol has an important role in membranes and in lipid metabolism in general, so is a lipid by any definition. I do not believe that all compounds that are soluble in organic solvents need be considered as lipids. The steroidal hormones, derived biosynthetically from cholesterol, are not lipids in the sense of my definition, and are not discussed further here. Cholesterol is formed biosynthetically from squalene via lanosterol as illustrated - It is a ubiquitous component of animal tissues and of fungi, where much of it is located in the membranes (as much as 30% of some membrane lipids). In plants, it tends to be a minor component only of a complex sterol fraction (see below). It occurs in the free form and esterified to long-chain fatty acids ( cholesterol esters ) in animal tissues, including the plasma lipoproteins. Animals in general synthesise a high proportion of their cholesterol requirement, but they can also ingest and absorb appreciable amounts in their diets. Many invertebrates, including insects, cannot synthesise cholesterol and must receive it from the diet; they can also make much more use of plant sterols than do higher animals.

Extractions: When the molecular basis of Tangier disease was discovered in 1999, researchers lined up to study this orphan genetic disorder. Patients with Tangier have a propensity for heart disease and atherosclerosis, making this rare malady a model for some pressing health problems found in industrialized nations. Following close behind the discovery of the Tangier gene were two studies, now deemed Hot Papers, that examined some of the molecular mechanisms upstream of the ATP-binding cassette A1 (ABCA1) involved in cholesterol transport and defective in patients with Tangier. One in vitro study demonstrated an orphan nuclear hormone receptor that senses the presence of cholesterol and turns on The second paper showed how molecules activating this gene and related pathways can block absorption of dietary cholesterol in mice. No one missed the obvious therapeutic applications, but figuring out how safely to flip the fat-sensing switch continues to elude them.

The genes, the researchers report, are essential for efficient secretion of cholesterol into the bile, which is the major route that cholesterol exits the body. The discovery sheds new light on potential therapies that could play an important role in reducing high cholesterol, a major risk factor of atherosclerotic diseases, such as coronary heart disease and stroke. The new findings are reported in this week's issue of the Proceedings of the National Academy of Sciences. "The disruption of the two genes, Abcg5 and Abcg8, reveals their crucial role in biliary cholesterol secretion," said Dr. Liqing Yu, an instructor in the Eugene McDermott Center for Human Growth and Development and in molecular genetics and lead author of the study.
