This study found that keratin coatings from human hair may improve the colony-forming efficiency of human mesenchymal stem cells by moderating donor variability, suggesting a potential use in clinical applications.

This study found that topically delivering KGF-1 DNA plasmid increased epithelial thickness and skin strength, suggesting potential benefits for strengthening compromised skin.

Keratin in mouse hair follicles is complex and plays specific roles.

Keratin structure changes during keratinization, but the exact model remains uncertain.

This study found that flutamide, finasteride, ketoconazole, and EE-CPA all significantly reduced hirsutism scores, hair diameter, and hair growth rate in women with hirsutism over 12 months.

Cepharanthine and minoxidil promote cell growth and delay hair cell maturation.

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 study found that the binding and release of BMP-2 from kerateine biomaterials are significantly influenced by pH and salt concentration, highlighting the potential for developing improved bone repair systems.

This study suggests that keratin peptide signatures in human hair shafts could potentially be used to distinguish gender and ethnicity, though further research on a larger scale is needed.

A specific gene mutation causes severe skin and nail issues and hair loss.

This study found that a composition including Serenoa repens extract and anti-inflammatory agents effectively suppressed inflammation-related gene expression in a keratinocyte model, suggesting a potential dual strategy for treating androgenetic alopecia.

In this case report, researchers identified Arthroderma vanbreuseghemii as the cause of a familial fungal infection, which was successfully treated with itraconazole and topical terbinafine cream.

Hair follicles form hard α-keratin filaments in four steps, showing structural differences.

This study identified and characterized a gene called 4C32, which is expressed in the periderm of embryonic mouse skin and has a structure similar to keratin-associated proteins.

This review summarizes recent advances in understanding intermediate filament structure and their implications for pathological mutations and human diseases, but it reports no new experimental results.

This review explores the "brain-skin connection" and presents evidence suggesting keloids may be influenced by psychosocial stress, although it reports no new experimental results.

This study suggests that the epidermis of monotremes and marsupials exhibits a more primitive pattern of protein distribution compared to eutherian mammals, with differences in loricrin distribution and keratinocyte maturation.

This study found that restoring vitamin D receptor expression in keratinocytes of VDR null mice prevents alopecia by enhancing the hair follicle's proliferative response during anagen initiation.

This study identified a novel human type I hair keratin, hHa3-II, as an isoform of a previously described hHa3 keratin, with distinct sequence differences indicating separate gene encoding.

This study suggests that androgens enhance growth factor production in dermal fibroblasts, which in turn may alter keratinocyte differentiation and contribute to acne lesion formation.

This study found that keratin derivatives with functionalized thiol groups improved binding to both natural and bleached hair fibers, suggesting a promising strategy for enhancing keratin's durability in hair repair.

This study identified and updated the annotation of 61 keratin genes in dogs and horses, improving the genome annotation in these species through RNA-seq data comparison.

This study found that three treatments with the 810-nm diode laser improved skin texture and roughness/bumpiness in keratosis pilaris patients, although it did not reduce redness.

This study found that MED1 deficiency in keratinocytes accelerates skin wound healing in young mice but delays healing in older mice, suggesting differential roles in epidermal regeneration with age.

This study found that at pH 9.0, CYS penetrated less and caused less damage to virgin human hair than TG because it barely reached the cortex region.

This study found that NGAL expression increased in calcium-induced keratinocyte differentiation in vitro and was highly elevated in psoriasis-like skin conditions and skin cancers, suggesting a role in skin hyperplasia and homeostasis.

This study found that polymorphisms in the KAP8.2 gene in Chinese Inner Mongolia cashmere goats are associated with variations in cashmere fibre diameter, suggesting its potential as a molecular marker for this trait.

Mutations in the hHb6 gene cause the hair disorder monilethrix.

The researchers reported that exposure to long days after short-day treatment induced a synchronized, out-of-season wool growth cycle in New Zealand Wiltshire sheep, similar to cycles induced in other species.

This study found that both ketoconazole 2% shampoo and selenium sulphide are effective for dandruff treatment, but ketoconazole also reduces hair growth.
