Abstract
The aim of this study was to evaluate the effect of atorvastatin on thrombospondin synthesis and secretion in human umbilical endothelial cells and its regulation by mevalonate or its derivatives. Our results show that atorvastatin decreased endothelial cell thrombospondin content and secretion in a dose-dependent manner. Mevalonate totally reversed the inhibitory effect produced by atorvastatin on the content and secretion of cellular thrombospondin. Farnesyl pyrophosphate and geranylgeranyl pyrophosphate reversed the inhibitory effect produced by atorvastatin on the cellular content of thrombospondin but did not prevent the inhibitory effect of atorvastatin on thrombospondin secretion. In conclusion, atorvastatin down-regulates thrombospondin in human endothelial cells through mevalonate inhibition.
