Loss-Of-Function Mutations of an Inhibitory Upstream ORF in the Human Hairless Transcript Cause Marie Unna Hereditary Hypotrichosis

research Loss-Of-Function Mutations of an Inhibitory Upstream ORF in the Human Hairless Transcript Cause Marie Unna Hereditary Hypotrichosis

181 citations , January 2009 in “Nature Genetics”

In this study, researchers linked defects in U2HR, an inhibitory region in the HR gene, to Marie Unna hereditary hypotrichosis, suggesting a mechanism for controlling hair growth and addressing hair loss.

research Hairless Is a Nuclear Receptor Corepressor Essential for Skin Function

30 citations , January 2009 in “Nuclear Receptor Signaling”

This study identified the Hairless (Hr) gene-encoded protein as a corepressor that plays a crucial role in maintaining skin and hair by regulating epithelial stem cell differentiation and gene expression via chromatin remodeling, which may impact both development and disease.

research Disruption of P2RY5, an Orphan G Protein–Coupled Receptor, Underlies Autosomal Recessive Woolly Hair

210 citations , February 2008 in “Nature genetics”

This study found mutations in the P2RY5 gene that are linked to autosomal recessive woolly hair in Pakistani families, implicating it in hair texture determination.

research Human Hair Growth Deficiency Is Linked to a Genetic Defect in the Phospholipase Gene LIPH

194 citations , November 2006 in “Science”

This study identified a gene mutation in the LIPH gene associated with inherited hair loss and hair growth defects in certain populations, suggesting lipase H plays a role in hair development.

research Hairless Triggers Reactivation of Hair Growth by Promoting Wnt Signaling

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.

research Physical And Functional Interaction Between The Vitamin D Receptor And Hairless Corepressor, Two Proteins Required For Hair Cycling

215 citations , September 2003 in “Journal of Biological Chemistry”

This study found that the hairless gene product (Hr) suppresses VDR-mediated gene activation by directly interacting with the vitamin D receptor, potentially affecting hair follicle function.

research Alopecia Universalis Associated With a Mutation in the Human Hairless Gene

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.
