"Data suggest expression of ECAD (E-cadherin) in bladder cancer cell lines correlates with presence of intercellular junctions and level of PAK5 (p21-activated kinase PAK5 protein) expression; endogenous PAK5 is localized to intercellular junctions and interacts with ECAD; depletion of PAK5 expression reduces integrity of intercellular junctions; PAK5 mRNA levels are reduced in bladder cancer compared with normal controls."xsd:string
