Radioprotection by glutathione ester: transport of glutathione ester into human lymphoid cells and fibroblasts.

Abstract

Glutathione is not effectively transported into human lymphoid cells, normal human skin fibroblasts, and fibroblasts from patients with genetic deficiencies of gamma-glutamylcysteine synthetase or glutathione synthetase. On the other hand, the monoethyl ester of glutathione, in which the carboxyl group of the glycine residue is esterified, is readily transported into these cells and is hydrolyzed intracellularly. This leads to greatly increased cellular levels of glutathione, which often exceed those found normally. Glutathione ester was found to protect human lymphoid cells of the CEM line against the lethal effects of irradiation. Under the conditions employed, complete protection was found when the ester was added prior to irradiation. Addition of the ester after irradiation was partially effective, suggesting that GSH may also function in repair processes.
