June 2013 in “Biochimica et biophysica acta. Molecular cell research” Cornification is how skin cells die to form the protective outer layer of skin, hair, and nails.
This study highlights the crucial role of ligand-independent actions of the vitamin D receptor (VDR) in maintaining hair cycle and skin homeostasis. In VDR-KO rats, which lack the VDR gene, there is significant alopecia and skin abnormalities, including hyperkeratosis and increased trans-epidermal water loss. In contrast, rats with a mutant VDR (R270L/H301Q) that cannot bind ligands do not exhibit these issues, indicating that VDR's non-liganded actions are essential. The study found that VDR-KO rats have altered gene and protein expression, particularly in the Shh, Wnt, and Bmp signaling pathways, with decreased hair keratins and increased epidermal keratins. These findings underscore the importance of non-liganded VDR in keratinocyte differentiation, proliferation, and cell death in hair follicles and the epidermis.
