Six 3-hydroxy-3-methylglutaryl coenzyme A (HMG-CoA) reductase inhibitors (the present cholesterol-lowering drugs known as statins), lovastatin (L), simvastatin (S), pravastatin (P), fluvastatin (F), atorvastatin (A) and cerivastatin (C) are shown to be potent inhibitors of cholesterol synthesis in human hepatocytes, the target tissue for these drugs in man.(More)
The effects of 6 HMG-CoA reductase inhibitors: pravastatin, lovastatin, simvastatin, atorvastatin, fluvastatin and cerivastatin were analyzed in cultured human smooth muscle cells, fibroblasts, endothelial cells and myoblasts. In vascular smooth muscle cells, pravastatin was a much weaker inhibitor of cholesterol synthesis than the 5 other drugs which(More)
In the present study, we have analyzed the response of human smooth muscle cell (SMC)s to oxidative stress, in terms of recruitment of key elements of the stress-activated protein kinase (SAPK) pathway, such as Rac(1), p38, and the small heat shock protein (HSP)27. The level of expression of three small HSPs, alphaB-crystallin, HSP20, HSP27, as well as the(More)
Lovastatin, simvastatin, and pravastatin are fairly strong inhibitors of sterol synthesis in human myoblasts in culture. Lovastatin and simvastatin have IC50 values of 19 +/- 6 nM and 4.0 +/- 2.3 nM, respectively. Pravastatin is a weaker inhibitor of sterol synthesis (IC50 value of 110 +/- 38 nM). Through inhibition of mevalonate production, these compounds(More)
The three vastatins examined, lovastatin, simvastatin and pravastatin, are equally strong inhibitors of the sterol synthesis in human hepatocytes in culture with IC50-values of 4.1, 8.0 and 2.0 nM, respectively. However, in the human extrahepatic cells: umbilical vascular endothelial cells, retinal pigment epithelial cells, cornea fibroblasts and granulosa(More)
Lovastatin and simvastatin are strong inhibitors of cholesterol synthesis in cultured human granulosa cells, as measured within 6 days after isolation, with IC50-values of respectively 27.0 and 18.2 nM obtained after 3.5 hours of incubation with the drugs. Pravastatin is a much weaker inhibitor of cholesterol synthesis (IC50-value of 977.8 nM) in these(More)
