In this study, researchers found that the absence of type I or type II keratins in mice leads to severe skin barrier defects, highlighting keratins' crucial role in epidermal structure and function.

In this study, hair composted with various organic materials, and inoculated with Bacillus subtilis, showed improved degradation and nutrient release, but temperatures below 33℃ limited composting efficiency, suggesting bacterial augmentation could aid sustainable management of keratin-rich waste.

In this preclinical study, researchers found that combining equal ratios of high molecular weight keratin intermediate filaments and low molecular weight keratin-associated proteins from human hair led to the most extensive fibrinogen precipitation, suggesting potential for developing effective hair protein-based hemostatic materials.

This study identified a novel keratin-associated protein, KAP24.1, which is specifically expressed in the human scalp and located in the hair cuticle.

This study found that keratin fibers like human hair undergo thermal and mechanical transitions that can help assess changes from cosmetic processes such as bleaching and perm-waving.

This study found that zinc is primarily located in the tails of mature rat sperm, associated with -S-S-bonded structures, and suggests a possible similarity in zinc interactions between sperm keratin and hair proteins.

This study proposes a new method to selectively isolate keratin-associated proteins and keratin from human hair, suggesting that KAPs may support keratin fibers in hair structure.

Glycoproteins are present in the cell membranes of various keratin fibers.

This study identified and characterized a murine type II hair keratin, demonstrating its presence in specific cells of hair and tongue tissues.

This study identified a single autosomal recessive gene responsible for hypotrichosis in a mutant rabbit strain, affecting hair growth and causing epidermal and hair follicle abnormalities.

In this study, researchers found a correlation between x-ray patterns and the element composition of human hair, with certain metal roles in the hair matrix considered.

The book discussed in this abstract is a comprehensive guide to hair analysis, detailing the latest methods and applications across various fields such as toxicology and drug monitoring, designed for both newcomers and experts in the field.

This study found that shampoo and conditioner do not alter hair's molecular structure, while perming treatments significantly affect keratin and intermediate filament structures due to bond alterations.

This study found that Cynatine HNS significantly improved hair and nail health in women after 90 days compared to placebo.

This article reviews the composition and structure of mammalian hard keratins, focusing on the filamentous and nonfilamentous protein content, and reports no new experimental results.

This review explains the mechanical composition and molecular interactions that determine hair's mechanical properties, without providing any new experimental findings.

This study found that blocking autophagy in Atg7-deficient mouse hair keratinocytes altered the molecular composition of hair shafts by increasing the abundance of proteins involved in protein turnover while keratins remained unchanged, highlighting autophagy's role in reducing non-cytoskeletal protein concentrations in hair.

This study found that down and guard hairs of Inner Mongolia Cashmere Goats have distinct protein compositions and physical properties, with keratin-related proteins potentially influencing these differences.

This article reviews the complex structure and molecular composition of hair keratins, highlighting their self-assembly process and implications for keratin extraction techniques, but reports no new experimental results.

This study observed that while X-ray radiation did not alter major hair keratin composition in mice, it decreased hair follicle stem cell markers and increased Krt5, suggesting potential as a radiation biomarker.

This study reported that genome sequencing and analysis of mink hair keratin genes reveal the amino acid composition of key proteins and offer insights into fur biosynthesis, potentially aiding conservation efforts through transgenic animal design to produce mink fur and help save endangered mink species.

This study observed that transgenic mice expressing keratin K10 under bovine K6beta control developed severe oral abnormalities, suggesting keratin composition changes can affect the physiology of epithelial cells, especially in the oral mucosa.

This study found that the mechanical stiffening of the human hair follicle along the first millimeter is linked to changes in the keratin network architecture and composition during keratinization.

This study reveals an antagonistic competition between BMP and Wnt signaling within stem cells, influencing their fate towards hair germ characteristics based on the BMP/Wnt activity ratio.

This study explored the structure and keratin composition of marsupial hairs, finding similarities in keratin localization to hairs in placental mammals, and highlighting potential roles of trichohyalin and transglutaminase during hair development and shedding.

This study describes the structure and composition of the epidermal horny layer in elephant seals, noting that its keratinized cells are attached without a specialized fission zone, differing from the sloughing mechanism in reptiles.

This study found that the Meibomian gland shares structural and cytokeratin composition similarities with hair follicles, and plays a role in hyper-keratinisation observed in obstructive Meibomian gland dysfunction.

This study suggests that analyzing the composition and modifications of hair proteins may provide new biomarkers for assessing hair health, diseases, and aging.

This study found that straight crimp mutant wool differs from crimpy wool in the layout of cortical cells and the relative proportions of keratin and keratin-associated proteins.
