3-Hydroxy-3-methylglutaryl-CoA (HMG-CoA) reductase is the major rate-limiting enzyme in sterol and non-sterol isoprenoid synthesis. Isoprenoids are involved in the mechanisms of cell proliferation and transformation leading notably to crucial post-translational maturation of small G-proteins of the Ras superfamily. HMG-CoA reductase is among the most highly regulated enzymes. It is controlled b...

Recent studies have shown that the administration of endotoxin (LPS) and cytokines to Syrian hamsters increases serum cholesterol levels, hepatic cholesterol synthesis, and the activity, protein levels, and mRNA levels of hepatic HMG-CoA reductase. Despite the greater than 10-fold increase in HMG-CoA reductase mRNA levels, LPS had only minimal effects on hepatic LDL receptor mRNA levels. In the...

MYC is a potential target for many cancers but is not amenable to existing pharmacologic approaches.Inhibition of 3-hydroxy-3-methylglutaryl-coenzyme A reductase (HMG-CoA reductase) by statins has shownpotential efficacy against a number of cancers. Here, we show that inhibition of HMG-CoA reductase byatorvastatin (AT) blocks both MYC phosphorylation and activation, suppressing ...

Inhibition of 3-hydroxy-3-methylglutaryl-coenzyme A reductase (HMG-CoA reductase) by statins has shown potential efficacy against a number of cancers.

Hydroxymethylglutaril-CoA reductase inhibitors/ therapeutic use; atrial fibrillation/prevention & control; postoperative period. Our group of studies on coronary heart diseases would like to congratulate the authors for the article by Alves et al1 for this relevant subject matter. We wished to report our opinion regarding the chronic use of preoperative statin and atrial fibrillation in the pos...

The corrole-based catalytic antioxidant reduced the cholesterol biosynthesis ability of macrophages, harvested from mice treated with it. and a non-redox active analogue of it affect the committed step of the biosynthetic pathway--the HMG-CoA reductase catalysed reaction--by acting as allosteric inhibitors of this key enzyme.

Recent studies have proposed an association between hyperlipidemia and venous thromboembolism (VTE). We review the epidemiological evidence linking dyslipidemia with VTE and examine several possible underlying mechanisms. We discuss the possible role of HMG CoA reductase inhibitors (statins) in the prevention and treatment of VTE and suggest future directions for research.

Erythromycin is an antibiotic useful for the treatment of a number of bacterial infections. This includes respiratory tract infections, skin infections, chlamydia infections, and syphilis. It may also be used during pregnancy to prevent Group B streptococcal infection in newborns [1]. It is an effective inhibitor of CYP3A4 that patently increases circulating levels of some other HMG-CoA reducta...

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,...

3-Hydroxy-3-methylglutaryl coenzyme A (HMG CoA) reductase inhibitors, commonly known as statins, are widely used clinically for their lipid lowering properties. Recent evidence shows that statins are also effective in ameliorating cerebral vasospasm, which occurs as sequelae of subarachnoid haemorrhage. This review focuses on the pleiotropic effects of statins, and the putative mechanisms invol...
