Oxidative stress increase is a key event for development of sensitivity-related illnesses (SRIs). The aim of this work was to evaluate the influence of a genetic variant in the antioxidant enzyme glutathione peroxidase (GPx1) on oxidative stress development in SRIs. Main methods GPx1 rs1800668 genotype, as well as glutathione, ubiquinone, and DNA damage were assessed in 34 SRI patients and 36 healthy subjects. Key findings Total glutathione, reduced/oxidized glutathione, and ubiquinone were significantly decreased in cases compared with controls, while DNA fragmentation was significantly increased in patients. However, these differences were not associated to GPx1 genetic background. Significance GPx1 rs1800668 polymorphism does not play a major role in SRI-related oxidative stress development.

Abstract

Oxidative stress increase is a key event for development of sensitivity-related illnesses (SRIs). The aim of this work was to evaluate the influence of a genetic variant in the antioxidant enzyme glutathione peroxidase (GPx1) on oxidative stress development in SRIs. Main methods GPx1 rs1800668 genotype, as well as glutathione, ubiquinone, and DNA damage were assessed in 34 SRI patients and 36 healthy subjects. Key findings Total glutathione, reduced/oxidized glutathione, and ubiquinone were significantly decreased in cases compared with controls, while DNA fragmentation was significantly increased in patients. However, these differences were not associated to GPx1 genetic background. Significance GPx1 rs1800668 polymorphism does not play a major role in SRI-related oxidative stress development.
