research pH Dependence of the Coiled-Coil Structure of Keratin Intermediate Filament in Human Hair by 13C NMR Spectroscopy and the Mechanism of Its Disruption
Keratin structure in hair is stable at pH 5-6 but disrupts between pH 6-7.
research Three-dimensional modelling of interchain sequence similarities and differences in the coiled-coil segments of keratin intermediate filament heterodimers highlight features important in assembly
Keratin heterodimers are preferred for their specific and structural advantages.
research Structural Stability of Wild Type and Mutated α-Keratin Fragments: Molecular Dynamics and Free Energy Calculations
The Glu413Lys mutation in keratin affects hair stability, while Glu413Asp does not.
research Carbon-13 n.m.r. studies of keratin intermediate filament of human hair
Human hair keratin has a 40% α-helix structure that changes to a random coil in 8 M urea.
research The structure of people’s hair
Hair's molecular structure is mostly consistent, but genetic differences affect lipid types, which could help diagnose diseases.
research Structural changes in the trichocyte intermediate filaments accompanying the transition from the reduced to the oxidized form
Oxidation changes the structure of hair protein filaments, causing them to compact and rearrange.
research Water distribution in human hair microstructure elucidated by spin contrast variation small-angle neutron scattering
The technique showed that human hair has two main parts, with 68% being rigid and the rest flexible, and water swelling affects its structure.
research Complete Structure of an Epithelial Keratin Dimer: Implications for Intermediate Filament Assembly
The study revealed the detailed structure of a keratin dimer, aiding understanding of how intermediate filament proteins function.
research Alopecia areata susceptibility variant in MHC region impacts expressions of genes contributing to hair keratinization and is involved in hair loss
A gene variant increases the risk of a type of hair loss by affecting hair protein production.
research Clinical Findings, Response to Steroid Treatment, and Recurrence Rate in Alopecia Areata Patients with or without a Nonsynonymous Variant of Coiled-Coil Alpha-Helical Rod Protein 1
Patients with a specific genetic variant have more severe alopecia areata and higher recurrence rates.
research Signal transducer and activator of transcription 5B deficiency due to a novel missense mutation in the coiled-coil domain
A boy's growth and immune problems were caused by a new mutation in the STAT5B gene.
research Effect of shampoo, conditioner and permanent waving on the molecular structure of human hair
Perming significantly changes hair's molecular structure, while shampoo and conditioner do not.
research Multiscale modelling of human hair
Human hair becomes weaker and stretches more easily at higher temperatures.
research HAIR KERATINIZATION IN HEALTH AND DISEASE
Understanding intermediate filaments helps explain hair health and related diseases.
research The Intermediate Filament Architecture as Determined by X-Ray Diffraction Modeling of Hard α-Keratin
Hard α-keratin in hair has a unique, nonordered structure, different from other fibers.
research Hair tourniquet syndrome of penis: A rare situation in boys with serious complications if not recognized
Hair wrapped tightly around a boy's penis can cause serious damage if not treated quickly.
research The structure of the “amorphous” matrix of keratins
Human hair keratin fibers have a detailed nano-scale structure that changes with different conditions.
research Structure of intermediate filament assembly in hair deduced from hydration studies using small-angle neutron scattering
Hair's internal fibers are arranged in a pattern that doesn't let much water in, and treatments like oils and heat change how much water hair can absorb.
research Structural Abnormalities in the Hair of a Patient with a Novel Ribosomopathy
The patient's hair was thinner and had fewer lipids due to a genetic mutation.
research Mutant laboratory mice with abnormalities in hair follicle morphogenesis, cycling, and/or structure: annotated tables
Mutant mice help researchers understand hair growth and related genetic factors.
research Development, Structure, and Keratin Expression in C57BL/6J Mouse Eccrine Glands
The study found that mouse sweat glands develop before birth, mature after birth, and have specific keratin patterns.
research Molecular modeling and structural characterization of a high glycine–tyrosine hair keratin associated protein
The 3D structure of a key hair protein was modeled, revealing specific helical structures and stabilization features.
research Local structure of human hair spatially resolved by sub-micron X-ray beam
Human hair has a new region with ordered filaments and the cuticle contains β-keratin sheets.
research Solid state NMR of isotope labelled murine fur: a powerful tool to study atomic level keratin structure and treatment effects
Solid-state NMR can effectively study keratin structure and treatment effects in fur.
research Influence of feed restriction on the wool proteome: A combined iTRAQ and fiber structural study
