Indicates test has been approved by the New York State Department of Health. 3-hydroxy-3-methyl-glutaryl-CoA reductase (HMG-CoA reductase) catalyzes the rate limiting step in cholesterol biosynthesis - conversion of 3-hydroxy-3-methyl-glutaryl-CoA to mevalonic acid. It is a type of HMG-CoA reductase inhibitor and a type of statin. Anti-HMG-CoA reductase antibody was positive in all cases tested (n = 57/57, 100%). Statins lower blood cholesterol levels by inhibiting HMG-CoA reductase, the rate-limiting enzyme in the biosynthesis of cholesterol. They are used to reduce the amount of cholesterol production in the body. It is bound to the ER membrane by a multi-pass 339 amino acid N-terminal transmembrane domain while the carboxy terminal catalytic region projects into the cytosol.

Background information for test. �������F����s����V0��h�޵�M� HMG-CoA reductase inhibitors include Pitavastatin, Rosuvastatin, lovastatin, Fluvastatin, and Simvastatin (Goldstein and Michael 163). In an NADPH-dependent reaction, HMG-CoA reductase reduces HMG-CoA to generate mevalonate and CoA. Necrotizing autoimmune myopathy (NAM) is a serious, but rare muscle disease strongly associated with autoantibodies to either signal recognition protein (SRP) or 3-hydroxy-3-methylglutaryl-CoA reductase (HMGCR). The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Normally in mammalian cells this enzyme is suppressed by cholesterol derived from the internalization and degradation of low density lipoprotein via the LDL receptor as well as oxidized species of cholesterol. Expected turnaround time for a result, beginning when ARUP has received the specimen. Keywords: Breast cancer, HMG-CoA reductase, Tumor characteristics, Treatment, Early breast cancer events, Prognosis Introduction New prognostic and treatment-predictive markers are needed to improve treatment decisions and consequently prognosis and treatment response in breast cancer patients. Reference range is 0-20 units. ���wG����㓲JrA�y�. HMG-CoA reductase is a transmembrane enzyme, bound to endoplasmic reticulum. Two enzymes which are potentially responsible for altered lipoprotein production and catabolism are 3-hydroxy-3-methylglutaryl coenzyme A reductase (EC 1.1.1.34, HMG-CoA reductase) and acyl-CoA:cholesterol acyltransferase (EC 2.3.1.1.26, ACAT), and … Codes reflect our interpretation of CPT coding requirements based upon AMA guidelines published annually, ARUP!
