Regulation of hepatic 3-hydroxy-3-methylglutaryl coenzyme A reductase and cholesterol synthesis.
Rat liver microsomal 3-hydroxy-3-methylglutaric acid (HMG)-coenzyme A reductase (mevalonate:NADP oxidoreductase (acylating CoA), EC 1.1.1.34) exhibits a cyclic rhythm with peak activity at midnight. HMG-CoA reductase from microsomes of rats killed at noon and midnight has similar properties. Cycloheximide completely prevents the 5to IO-fold rise in activity which occurs from 6 p.m. to midnight,...
متن کاملRegulation of 3-hydroxy-3-methylglutaryl coenzyme A reductase activity and cholesterol biosynthesis by oxylanosterols.
Treatment of rat intestinal epithelial cell cultures with the oxidosqualene cyclase inhibitor, 3 beta-[2-(diethylamino)-ethoxy]androst-5-en-17-one (U18666A), resulted in an accumulation of squalene 2,3:22,23-dioxide (SDO). When U18666A was withdrawn and the cells were treated with the sterol 14 alpha-demethylase inhibitor, ketoconazole, SDO was metabolized to a product identified as 24(S),25-ep...
متن کاملTocotrienols regulate cholesterol production in mammalian cells by post-transcriptional suppression of 3-hydroxy-3-methylglutaryl-coenzyme A reductase.
Tocotrienols are natural farnesylated analogues of tocopherols which decrease hepatic cholesterol production and reduce plasma cholesterol levels in animals. For several cultured cell types, incubation with gamma-tocotrienol inhibited the rate of [14C]acetate but not [3H] mevalonate incorporation into cholesterol in a concentration- and time-dependent manner, with 50% inhibition at approximatel...
متن کاملPurification of 3-hydroxy-3-methylglutaryl coenzyme A reductase.
The enzyme 3-hydroxy-3-methylglutaryl coenzyme agarose, glucose-6-phosphate dehydrogenase, and aldolA reductase from human liver was purified to homogeneity. ase were from Sigma Chemical co.; agarose-hexaneHMG-CoA was from P-L Biochemicals; bovine serum Electrophoresis of the purified human enzyme on non-denaturing gels revealed a single protein-staining band that co-migrated with reductase act...
متن کاملHepatic cholesterol metabolism in obesity: activity of microsomal 3-hydroxy-3-methylglutaryl coenzyme A reductase.
Obesity is often associated with an elevated total body cholesterol synthesis. In order to evaluate the role of hepatic cholesterogenesis in this phenomenon, we assayed the rate-limiting step in cholesterol biosynthesis, 3-hydroxy-3-methylglutaryl coenzyme A (HMG CoA) reductase in the microsomal fraction of liver biopsies obtained operatively from ten morbidly obese (relative body weight greate...
