title: [High cholesterol level upregulate the expression of caveolin-1].
abstract: To study the influence of hypercholesterolemia with caveolin-1 on the plasmalemma of vascular endothelium, we used the methods of immunohistochemistry to detect the dynamic changes of caveolin-1 in cultured ECV-304 cells which were stimulated high cholesterol serum and the arterial endothelium of hypercholesterolemia rats. It is resulted that high cholesteorol level can upregulate the expression of caveolin-1 both in vitro and in vivo. In the initial stage of hypercholesterolemia model, the expression of caveolin-1 increased as the time of high cholesterol level added, but in the later period it was decreased slightly.
