Inhibition of oxidant-induced barrier disruption and protein tyrosine phosphorylation in Caco-2 cell monolayers by epidermal growth factor.


The effect of epidermal growth factor (EGF) on the H202-induced increase in paracellular permeability in Caco-2 and T-84 cell monolayers was evaluated to examine the role of EGF in intestinal mucosal protection from oxidative stress. Oxidative stress was induced by exposing cell monolayers to H2O2 or a mixture of xanthine oxidase + xanthine (XO + X… (More)
