title: Enhancement of migration activity in cholesterol-poor endothelial cells by pre-treating with HMG-CoA reductase inhibitors.
abstract: When bovine endothelial cells isolated from carotid arteries were cultured with a low density lipoprotein(LDL)-deficient serum for 2 days, their intracellular free cholesterol levels decreased. Under this condition, exposure of the endothelial cells to simvastatin and pravastatin, HMG-CoA reductase inhibitors used clinically, resulted in further decrease in the free cholesterol levels. The migration activity was enhanced in the cells cultured with the LDL-deficient serum and it was more enhanced in the cells treated with HMG-CoA reductase inhibitors under the LDL-deficient serum condition. These results suggest that cholesterol plays a negative role in wound healing in arterial walls and acts as one of the risk factors for arteriosclerosis.
