In skin fibroblasts grown from four children with a homozygous form of type II hyperlipoproteinemia, the feedback control of sterol synthesis and the inhibitory effect on hydroxymethylglutaryl (HMG) CoA reductase activity by serum or low density lipoprotein were present, though diminished compared with the effects in normal fibroblasts. Stimulation of HMG CoA reductase by insulin and inhibition...

The case of a 68-year-old woman with purpura nephritis associated with nephrotic syndrome is herein described. The patient's clinical course and the findings of a renal biopsy study revealed purpura nephritis. Following treatment with corticosteroids and intravenous cyclophosphamide accompanied by an angiotensin II type I receptor-blocker, an anti-platelet drug and an hydroxymethylglutaryl (HMG...

A beta-lactone isolated from Fusarium sp. has been shown to be a potent specific inhibitor of the enzyme 3-hydroxy-3-methylglutaryl coenzyme A (HMG-CoA) synthase [(S)-3-hydroxy-3-methylglutaryl-CoA acetoacetyl-CoA-lyase (CoA-acetylating), EC, 4.1.3.5] from rat liver. The structure of this beta-lactone, termed L-659,699, is (E,E)-11-[3-(hydroxy-methyl)-4-oxo-2-oxytanyl]-3,5,7-trimethyl-2,4 - und...

Aneurysmal subarachnoid hemorrhage (SAH) has the highest morbidity and mortality rates of all types of stroke. Many aneurysmal SAH patients continue to suffer from significant neurological morbidity and mortality directly related to delayed cerebral ischemia. Pilot clinical studies of the use of Hydroxymethylglutaryl-CoA Reductase Inhibitors (statins) in aneurysmal SAH patients have reported a ...

Hydroxymethylglutaryl Co-enzyme A reductase inhibitors, also known as statins, are a class of anti-hyperlipidemic agents. These drugs have been employed vastly to reduce the morbidity and mortality of cardiovascular disorders. Soon after their introduction, benefits other than their primary actions were discovered. Along with these pleiotropic properties, a series of mainly favorable effects ha...
