As VE-cadherin tyrosine phosphorylation sites have never been explored in human tumor tissues, we analyzed phospho-VE-cadherin tyrosine sites in GBM extracts, using two commercial anti-VE-cadherin phosphosites directed against sites Y658 and Y731 and an antibody anti-phosphoY685 raised in our laboratories. Here, CDH5 is linked to neoplasm.
