January 2012 in “Annals of dermatology/Annals of Dermatology” This case report describes a 7-year-old boy with alopecia areata and reduced vitamin D receptor expression whose condition improved after using calcipotriol, a strong vitamin D analog.
88 citations
,
February 2011 in “Journal of Dermatological Science” This study found that topical minoxidil modestly extended the anagen phase in mice by activating β-catenin activity in dermal papilla cells.
143 citations
,
May 2007 in “Proceedings of the National Academy of Sciences” This study found that absence of the vitamin D receptor in keratinocytes impairs canonical Wnt signaling and leads to alopecia due to defects in keratinocyte stem cells.
788 citations
,
February 2007 in “Nature” This review explores how adult skin epithelia preserve stem cell populations for hair follicle regeneration and wound healing, but reports no new experimental results.
111 citations
,
April 2006 in “Annals of the New York Academy of Sciences” This study found that preventing abnormal mineral ion homeostasis in vitamin D receptor knockout mice stopped bone abnormalities, while the animal's skin phenotype arose from direct receptor effects independent of vitamin D.
78 citations
,
November 2005 in “Endocrinology” This study found that Hairless (Hr) acts as a corepressor of the vitamin D receptor (VDR) in human keratinocytes, blocking the action of vitamin D on keratinocyte differentiation.
137 citations
,
September 2005 in “Proceedings of the National Academy of Sciences of the United States of America” In this study, researchers found that transgenic expression of the Hairless gene in keratinocytes can restore hair follicle regeneration in Hr-deficient mice by repressing Wise, a modulator of Wnt signaling.
144 citations
,
December 2004 in “Molecular Endocrinology” This study found that the effects of the vitamin D receptor on hair follicle cycling in mice are independent of its ability to bind a hormone, with specific domain mutations influencing hair regrowth outcomes.
114 citations
,
June 2000 in “Endocrinology” In this study, the researchers found that alopecia in VDR null mice is likely due to issues with hair cycle initiation rather than defects in keratinocyte proliferation or differentiation.
30 citations
,
December 1999 in “Journal of Investigative Dermatology Symposium Proceedings” This study found that in vitro treatments with 5alpha-reductase inhibitors and androgen receptor antagonists strongly stimulate VEGF expression in dermal papilla cells.
412 citations
,
January 1998 in “Science” This study identified a missense mutation in the human hairless gene associated with a rare form of recessively inherited alopecia universalis, pinpointed on chromosome 8p12.
