Oxidative stress can lead to cellular injury and apoptosis within the pulmonary allograft. We investigated the effects of oxidative damage on the growth and survival of cultured human pulmonary epithelial cells treated with hydrogen peroxide (H2O2) in the presence and absence of cyclosporin A (CsA) and tacrolimus. Treatment of A549 cells with 1 mmol/l H 2O2 for 48 h led to a 39% decrease in cell growth. Treatment with 500 ng/ml CsA for 48 h reduced cell survival by 68%, and treatment with 30 ng/ml tacrolimus reduced cell survival by 32%. The addition of CsA or tacrolimus to cells grown in H2O2 did not further diminish cell survival. These studies demonstrated that H 2O2, CsA, and tacrolimus treatments decrease survival of pulmonary epithelial cells. However, CsA and tacrolimus do not further potentiate H2O2-induced toxicity.
