ZO-1, β-catenin, VE-Cadherin and VEGFR-2 are in the same immunocomplex. Immunoprecipitation with VE-cadherin antibody showed constitutive association between VE-cadherin, VEGFR-2, β-catenin and ZO-1. In the figure C-V is control, HUVEC without any VPF/VEGF or dopamine treatment, C+V is the HUVEC treated with only VPF/VEGF (10 ng/ml) for 5 min, D-V is the HUVEC treated with 10 μM dopamine for 15 min and D+V is the HUVEC pretreated with 10 μM dopamine for 15 min and then treated with VPF/VEGF (10 ng/ml) for 5 min. The figures are representative of three separate experiments with similar results.
