Mechanisms of Hair Graying: Incomplete Melanocyte Stem Cell Maintenance in the Niche
Emi K. Nishimura,1* Scott R. Granter,2 David E. Fisher1*

Hair graying is the most obvious sign of aging in humans, yet its mechanism is largely unknown. Here, we used melanocyte-tagged transgenic mice and aging human hair follicles to demonstrate that hair graying is caused by defective self-maintenance of melanocyte stem cells. This process is accelerated dramatically with Bcl2 deficiency, which causes selective apoptosis of melanocyte stem cells, but not of differentiated melanocytes, within the niche at their entry into the dormant state. Furthermore, physiologic aging of melanocyte stem cells was associated with ectopic pigmentation or differentiation within the niche, a process accelerated by mutation of the melanocyte master transcriptional regulator Mitf.

Abstract;Werner's syndrome (W), one of hereditary progeria, is generally short stature with developing cataract, gray hair and hair removal from about 20 years old, and shows high frequency of malignant tumor. RNA of the cause gene of W is length of about 5.8kb, and it is acidic protein (DNA helicase) consisting of 1432 amino acids. In the causal gene mutation of W, a type, in which the translation of the protein has stopped due to single base substitution of the protein translation region during the translation and a type in which the abnormal splicing occurs due to the mutation of the connecting point of exon and intron in mRNA. The causal gene of Bloom's syndrome, a part of complementary group of Cokayne's syndrome and a part of complementary group of xeroderma pigmentosum except for W are protein with the helicase domain.
