1 Atorvastatin preserves the integrity of endothelial adherens junctions by inhibiting vascular endothelial cadherin tyrosine phosphorylation. Tyrosine cadherin 5 Homo sapiens
2 Vascular endothelial cadherin (VE-cad) tyrosine (Tyr) phosphorylation has been implicated in the disruption of adherens junctions (AJs) induced by inflammatory reactions. Tyrosine cadherin 5 Homo sapiens
3 Vascular endothelial cadherin (VE-cad) tyrosine (Tyr) phosphorylation has been implicated in the disruption of adherens junctions (AJs) induced by inflammatory reactions. Tyrosine cadherin 5 Homo sapiens
4 Vascular endothelial cadherin (VE-cad) tyrosine (Tyr) phosphorylation has been implicated in the disruption of adherens junctions (AJs) induced by inflammatory reactions. Tyrosine cadherin 5 Homo sapiens
5 Vascular endothelial cadherin (VE-cad) tyrosine (Tyr) phosphorylation has been implicated in the disruption of adherens junctions (AJs) induced by inflammatory reactions. Tyrosine cadherin 5 Homo sapiens
6 In ECs treated with interleukin (IL)-1beta for 30 min, VE-cad Tyr phosphorylation, dissociation of the VE-cad/beta-catenin complex and transendothelial migration (TEM) of monocytes were increased. Tyrosine cadherin 5 Homo sapiens
7 Atorvastatin inhibited IL-1beta-induced Tyr phosphorylation of VE-cad by inhibiting RhoA and by dephosphorylating MLC. Tyrosine cadherin 5 Homo sapiens
8 The attenuating effect of atorvastatin on VE-cad Tyr phosphorylation was reversed when RhoA was activated or MLC phosphatase was inhibited. Tyrosine cadherin 5 Homo sapiens
9 Furthermore, inhibiting farnesyl transferase or geranylgeranyl transferase reproduced the inhibitory effects of atorvastatin on VE-cad Tyr phosphorylation. Tyrosine cadherin 5 Homo sapiens
10 In addition, atorvastatin inhibited monocyte-induced VE-cad Tyr phosphorylation in ECs and attenuated IL-1beta-induced TEM of monocytes. Tyrosine cadherin 5 Homo sapiens
11 Our study introduces a novel pleiotropic effect of atorvastatin and suggests that statins protect the integrity of AJs in ECs by inhibiting RhoA-mediated Tyr phosphorylation of VE-cad. Tyrosine cadherin 5 Homo sapiens
