Abstract:

We have employed a model in vitro system for iron-peroxide-catalyzed oxidation of porphyrinogens to investigate the potential role of glutathione (GSH) in trace metal-induced porphyrias. GSH strongly attenuates porphyrinogen oxidation at biologically relevant concentrations in a dose-dependent manner. Porphyrinogenic trace metals reduce the effectiveness of GSH as a porphyrinogen antioxidant, leading to significantly higher rates of porphyrinogen oxidation to porphyrins. These observations may, in part, underlie the etiology of porphyrinurias induced during prolonged trace metal exposures.
