Extractions: January 16, 2001 wo groups of researchers have identified genes that may cause sitosterolemia, an uncommon genetic cholesterol disorder. The disorder is due to defects in cells that distinguish and selectively eliminate different types of dietary cholesterol. Sitosterolemia patients have elevated levels of cholesterol in blood and accumulate plant 'sterols' in tissues, putting them at risk for heart disease at an early age. (The primary plant sterol is sitosterol; hence the name, sitosterolemia.) Shailendra B. Patel, of the Medical University of South Carolina, in Charleston, and colleagues report this month that nine unrelated individuals with sitosterolemia have defects in the gene. Patel's group hypothesizes that the gene is important in the regulation of cholesterol absorption, a process that has long been a mystery in the lipid metabolism field. The findings appear in

Participants will have a medical history and physical examination and will be randomly assigned to one of two treatment groups. One group, which will include about 80 percent of all study participants, will take 10 mg of Ezetimibe a day, and the second group (20 percent of participants) will take a placebo (an inactive look-a-like pill). Patients will have 7 clinic visits during the 12-week study, when some or all of the following procedures and tests will be done: - Measurement of vital signs (heart rate, blood pressure, breathing rate and temperature) - Dietary maintenance - interview about how well that patient is adhering to the diet - Medication review - interview about other medications the patient is taking - Blood draw for tests - Urine sample for tests - Pregnancy test for women of childbearing potential - Electrocardiogram (ECG) to measure the electrical activity of the heart - Blood draw to determine sitosterol, other plant sterol levels, and lipid levels (cholesterol and other blood lipid concentrations)

Extractions: By Dustin Mark Familial hypercholesterolemia (FH) is caused by a mutation in the gene for the LDL receptor, which is instrumental in the removal of LDL particles from the blood. These individuals tend to have cholesterol levels around 300 mg/dL. The frequency of FH heterozygotes (who have half of their LDL receptors damaged) is roughly 1:500. Like all people with high cholesterol, these individuals are increasingly subject to atherosclerosis, often manifested in coronary heart disease. FH homozygotes, in whom LDL receptors are defective, have such severe hypercholesterolemia (around 650 mg/dL), that they often die from heart attacks in early childhood. The second most common disease in the group, familial ligand defective apoB-100, is less severe than FH and has an incidence around 1:1000 for heterozygotes. This disease results from a defect in the ligand for the LDL receptor, apoB-100 (found in LDL particles), which decreases the ability of LDL receptor to clear LDL particles from the blood, resulting in abnormally elevated LDL serum levels. The most recently discovered disease, autosomal recessive hyperchosterolemia (ARH), is described in the May 18 issue of Science. Briefly, this disease approaches the severity of homozygous FH, and is distinguishable primarily at the genetic level. Children and adolescents with ARH often suffer from premature coronary heart disease and usually have massive deposits of LDL-derived cholesterol in the skin. Unlike with FH, heterozygotes for ARH have completely normal cholesterol levels. The disease-causing mutations occur in a gene that codes for a previously undescribed cytosolic protein, aptly named ARH. This protein seems to function in either the internalization of the LDL receptor, an act that is necessary for the removal of LDL particles from the blood, or the recycling of the LDL receptor back to the surface of cells. Either way, the lack of functional ARH prevents cells from extracting LDL particles from the circulation.

The Scientist :: Cholesterol Efflux Genes sitosterolemia is a rare inherited disease in which plantderived sterols (sitosterol)accumulate in the body and lead to premature atherosclerotic plaques. http://www.biomedcentral.com/news/20021119/02
Extractions: Sitosterolemia is a rare inherited disease in which plant-derived sterols (sitosterol) accumulate in the body and lead to premature atherosclerotic plaques. The disease is caused by mutations in either of two ATP-binding cassette (ABC) half-transporters, ABCG5 or ABCG8 , but the exact role of these genes in the trafficking of sterols has been unclear. In November 18 early edition of Proceedings of the National Academy of Sciences , Liqing Yu and colleagues at the University of Texas Southwestern Medical Center at Dallas, USA, show that ABCG5 and ABCG8 are the major hepatobiliary transporter of both dietary and endogenously synthesized neutral sterols ( PNAS , cgi/doi/10.1073/pnas.252582399, November 18, 2002). Yu et al. generated mice homozygous for a disrupted Abcg5 and Abcg8 allele (G5G8 ), which they examined for the absorption and secretion of the major dietary plant and animal sterols. They observed that G5G8 mice had a two to threefold increase in the fractional absorption of dietary plant sterols, which was associated with an approximate 30-fold increase in plasma sitosterol. In addition they also observed a selective and profound reduction in biliary cholesterol levels and an accumulation of cholesterol in the liver after cholesterol feeding. "The G5G8 mice generated here provide a useful animal model to further probe the trafficking of sterols into and out of the body and to screen for agents that may affect this important pathway", conclude the authors.

A unique feature of this inherited form of severe hypercholesterolemia is the extreme responsiveness of the plasma cholesterol level to changes in dietary sterol intake. We studying the mechanism by which ABCG5 and ABCG8 protect against the accretion of sterols by the body at the molecular, cellular and whole animal level. These mechanistic studies are being complemented with family and population studies in humans to examine the effects of sequence variations in these genes on plasma sterol levels, the efficiency of cholesterol absorption, and the development of gallstones.
