Studysummary Proteomic analysis can identify genetic differences in mouse hair, helping understand hair defects and variations. Our plain-language summary of this paper — not a Tressless recommendation.

The study used proteomic analysis to investigate differences in pelage hair among three mouse strains: AKR/J-hid/hid, FVB/NJ+/+, and LP/J+/+. It identified 111 proteins in AKR/J-hid/hid mice, highlighting deficiencies in cortical cell projections and lower trichohyalin levels, which may contribute to their hair defect. Significant differences in 65 proteins were found across the strains, with AKR/J mice showing unique proteins not present in others. The research demonstrated the utility of proteomic analysis in distinguishing genetic variations in hair structure and provided insights into the molecular basis of hair defects, suggesting potential applications for understanding human hair variations.

research The Catalog of Human Hair Keratins

272 citations , September 2001 in “Journal of Biological Chemistry”

This study cataloged human type II hair keratins, detailing their expression and differentiation roles in hair follicles and comparing them with type I keratins to explore keratin-pairing principles.

research The Catalog of Human Hair Keratins

235 citations , July 1999 in “Journal of biological chemistry/The Journal of biological chemistry”

This study establishes a catalog of human type I hair keratins and identifies their specific roles and expression patterns during hair differentiation and growth in scalp follicles.

research Cross-Linked Features of Mouse Pelage Hair Resistant to Detergent Extraction

15 citations , February 1999 in “The anatomical record”

This study found that defective cross-linking in hair cuticles is observable in a minority of mouse hair mutants, suggesting different proteins are involved in cross-linking across cell types.

research Ultrastructural Visualization of Cross-Linked Protein Features in Epidermal Appendages

43 citations , July 1994 in “Journal of Cell Science”

This study found that the extraction-resistant structures in hair, feathers, and hagfish teeth are due to ε-(γ-glutamyl)lysine cross-linked proteins, emphasizing their role in maintaining the integrity of these materials.
