    Studysummary In this study, Dguok deficiency in mice led to premature hair greying due to a loss of melanocyte stem cells and mature melanocytes, with increased oxidative stress and cell death; treatment with an antioxidant mitigated these effects, suggesting DGUOK's importance in hair pigmentation maintenance.
