1 Thrombin-induced rapid geranylgeranylation was inhibited by acute short term (3 min) pretreatment with atorvastatin as well as by an inhibitor of GGTase I (GGTI-286). Atorvastatin coagulation factor II, thrombin Homo sapiens
2 Thrombin also rapidly stimulated GTP loading of RhoA, which was blocked by acute pretreatment with either atorvastatin or GGTI-286. Atorvastatin coagulation factor II, thrombin Homo sapiens
3 Importantly, the addition of geranylgeranylpyrophosphate to ECs pretreated with atorvastatin quickly reversed the atorvastatin inhibition of thrombin stimulation of RhoA. Atorvastatin coagulation factor II, thrombin Homo sapiens
4 Importantly, the addition of geranylgeranylpyrophosphate to ECs pretreated with atorvastatin quickly reversed the atorvastatin inhibition of thrombin stimulation of RhoA. Atorvastatin coagulation factor II, thrombin Homo sapiens
5 Cytoskeleton analysis demonstrated that atorvastatin and GGTI-286 inhibited thrombin-induced stress fiber formation. Atorvastatin coagulation factor II, thrombin Homo sapiens
