This study found that L-cystine-modified rabbit hair fibers had improved dye adsorption and spinnability, due to changes in secondary structure and surface characteristics.

Human hair structure varies by ethnicity, and certain treatments can improve hair condition and appearance.

This review classifies mutant mice with hair abnormalities into six categories, providing an annotated table that serves as a reference for understanding the molecular controls of hair growth.

This review presents updated tables of mouse mutants with hair growth abnormalities to aid in understanding the molecular mechanisms of human hair disorders, but reports no new clinical results.

This study presents computational modeling and experimental analysis of the HGT protein KAP8.1, identifying key structural features that may influence hair's response to environmental conditions.

This study found that specific mutations in the spike protein of SARS-CoV-2 may significantly alter its structure and affect how it binds to certain inhibitors, but experimental studies are needed to confirm potential clinical implications.

This study provides the first crystal structure of the human SRD5A2 enzyme, revealing key insights into its function and inhibition which may aid future drug development.

This study found that the cytochrome P450 enzyme CYP-sb21 can hydroxylate cyclosporine A at multiple positions, reducing its immunosuppressive effects but retaining its hair growth-promoting side-effect, and suggests modifications to improve regioselectivity for commercial use.

This study on Indian dromedary camel breeds investigated the KRTAP7 protein, finding all four breeds shared an identical gene sequence, with 13 phosphorylation and glycosylation sites influencing hair characteristics, alongside predicted interactions with other biosynthesis-related proteins.

This study optimized the extraction process for abomasum protein from Tianshan red deer, identifying two proteins with anti-inflammatory and anti-tumor activities, suggesting they could be beneficial in foods and nutraceuticals.

This study found that patients with androgenetic alopecia showed distinct scalp bacterial imbalances compared to healthy individuals, which were associated with unhealthy lifestyles. These microbial changes might contribute to follicular inflammation, potentially accelerating hair loss in these patients.

This study found that finasteride competitively inhibits the enzyme AKR1D1 with low micromolar affinity but does not act as a mechanism-based inactivator.

This study developed a method to culture and maintain chicken feather follicles in vitro, preserving structure and biology similar to their in vivo state, though some gene expression was altered.

This paper discusses the use of Digital Volumetric Imaging with fluorescent dyes to visualize and compare the interior structures of six different virgin hair types, reporting no new clinical results.

This study found that taxol induces apoptosis in dermal papilla cells, affecting protein expression related to biological processes and potentially contributing to taxol-induced alopecia.

This study demonstrated that molecular dynamics simulations of keratin could effectively model the mechanical properties of hair, aligning well with experimental data, especially when conducted in vacuum conditions.

This study found that pelage abnormalities in Harlequin mutant mice are linked to severe AIF deficiency and associated with altered expression of genes related to hair structure.

This study found that certain tandem repeats predict darker hair color across diverse ancestry groups and can contribute to a polygenic score for hair color, independent of SNP variation.

This study synthesizes knowledge of how dendritic cell signals, epithelial integrins, and fibroblast activity converge on TGF-β1 to maintain or disrupt skin healing, contrasting normal and fibrotic scar formation and suggesting possible integrin and immune-targeted treatments for skin fibrosis.

In this study, reducing agents like ammonium thioglycolate, L-cysteine, and sodium sulfite in shampoo effectively decreased hair flyaway and frizz without causing damage, as no critical hair damage was observed in structural and tensile strength assessments.

In this study, researchers found that trichothiodystrophy hair brittleness is linked to abnormalities in sulfur content and structural organization, making it prone to breakage.

This study presents the first detailed 3D models of the complete K1/K10 keratin dimer and identifies structural features and interactions that may inform understanding of keratin filament assembly.

This review discusses the formation and structure of the cornified cell envelope in the epidermis, highlighting biochemical pathways and genetic factors, but presents no new experimental results.

This article discusses the structure of hair follicles and their significance in evaluating hair disorders, but it does not report any new research findings.

This review discusses the structure and function of steroid nuclear receptors, particularly focusing on androgen receptor dysregulation in prostate cancer and androgen insensitivity syndromes, without reporting new experimental results.

This study characterized the Hoxc-13 gene from sheep wool follicles, noting its potential autoregulatory role and potential influence on skin function beyond hair keratin regulation.

This research identified two genetic variants that influence the white-spotted coat patterns in Holstein-Friesian cattle, involving regulatory changes in the MITF and KIT genes, confirmed through mouse models, along with possible effects on coat patterns in other cattle breeds.

This article reviews the structure, genomic organization, and pathogenesis of SARS-CoV-2 and discusses current efforts in prevention and treatments for COVID-19 without reporting new clinical results.

In this study, the authors identified and characterized the Get3d protein, conserved across plants and photosynthetic bacteria, which localizes to the chloroplast in Arabidopsis thaliana and potentially plays a role in tail-anchored protein targeting, linked to photosynthesis homeostasis.

New mutations in hair keratin genes can change hair structure and cause monilethrix, with nail issues more common in certain gene mutations.
