Huntington's disease

Glutathione peroxidase 1 (GPX1); glutathione peroxidase 3 plasma (GPX3)

Yeast and fly studies suggest glutathione peroxidase mimics could be used to treat Huntington's disease. In a yeast-based, genome-wide screen, gpx1 and gpx3 were identified as suppressors of mutant huntingtin (htt) protein toxicity. In a Drosophila model of Huntington's disease, a glutathione peroxidase mimic decreased degeneration of photoreceptor neurons compared with no treatment and restored normal locomotor activity. Next steps include testing glutathione peroxidase mimics in mouse models of Huntington's disease.
