H(2)O(2)-mediated permeability II: importance of tyrosine phosphatase and kinase activity.

Abstract

We previously reported that exposure of endothelial cells to H(2)O(2) results in a loss of cell-cell apposition and increased endothelial solute permeability. The purpose of this study was to determine how tyrosine phosphorylation and tyrosine phosphatases contribute to oxidant-mediated disorganization of endothelial cell junctions. We found that H(2)O(2… (More)
