June 2025 in “Cell Regeneration” 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.
June 2020 in “Faculty Opinions – Post-Publication Peer Review of the Biomedical Literature” This abstract provides logistical details about a research study on hair greying in RTX-injected mice but reports no specific findings or results.

September 2012 in “Cell Reports” In this study, knockout of B-raf and C-raf genes in mice showed they are not needed for early melanocyte development, but are crucial for maintaining melanocyte stem cells, as evidenced by hair graying due to stem cell depletion.

May 2011 in “Pigment Cell & Melanoma Research” In this study, Tanimura et al. reported that loss of collagen XVII in mice leads to hair loss and pigmentation defects, potentially due to impaired TGF-beta signaling affecting melanocyte stem cell maintenance.
