This study observed that Trps1 gene expression in mice is precisely regulated in skin development, particularly during hair follicle morphogenesis, with distinct localization patterns in different cell types.

This article reviews cytokeratin expression patterns in epithelial tissues and tumors, suggesting these patterns can aid in differentiating primary and metastatic carcinomas, without presenting new clinical results.

This study observed that ECMs produced by papillary fibroblasts showed the largest fibers and supported keratinocyte differentiation better than reticular fibroblast matrices, informing biomimetic material design for skin tissue engineering.

This article reviews the role and clinical applications of 1,25-dihydroxyvitamin D3 and parathyroid hormone-related peptide in dermatology, with a focus on psoriasis treatment, and reports no new experimental findings.

This review discusses the potential of protein-based cosmetics, including keratin-based particles and fusion proteins, to improve hair properties such as strength and shape, but it reports no new clinical results.

Mice with extra sheep genes had hair that fell out and regrew in cycles.

New mutations in hair keratin genes cause the rare hair disorder monilethrix.

This study identified two types of hard alpha-keratin filament assemblies in developing human hair follicles, which may help investigate the structural framework of mammalian keratin appendages.

This study found that variations in (CAG)n and (GGN)n polymorphisms in the androgen receptor gene appear to influence symptom severity in men with post-finasteride syndrome.

This study reveals that β-catenin and retinoic acid are key regulators in the gene networks controlling the fate of skin appendages, such as scales and feathers.

This review discusses spatial and temporal patterns in animals, focusing on skin appendage organs, but provides no new research findings.

This study provided new insights into the complex and heterogeneous architecture of keratin filaments, revealing their dynamic and flexible structure through cryo-electron microscopy analysis.

This study reports that mutations in human L-PGDS affect the entrance and exit of ligands in its binding cavity, suggesting these residues play a role in ligand interaction processes.

This article reviews the challenges in studying keratin proteins and emphasizes the potential of modern proteomic techniques to advance their research, but it reports no new findings.

This study found that trichohyalin is expressed in various normal and pathological epithelia beyond hair follicle cells, where it is uniquely associated with filaggrin, suggesting a specific role in aggregating K6/K16-containing intermediate filaments.

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 article reviews the molecular characteristics of human hair keratins, noting their distinct classification from epidermal keratins and the variability in expression that may occur without noticeable hair changes, but reports no new study results.

This study found that prostasin's proteolytic activity is necessary for normal hair follicle development in mice, but not for interfollicular epidermal development.

This study found that proteins secreted by early-passage dermal papilla cells, including SDF1, MMP3, biglycan, and LTBP1, may play significant roles in hair follicle regeneration.

This study achieved a first by successfully forming large quantities of dermal papilla spheroidal microtissues, which retained their hair induction potential, using a micropatterned culture system.

This case report describes an adolescent female with a linear array of trichoepitheliomas on her left neck, highlighting the clinical presentation of this benign tumor.

This study suggests that increased amounts of less stable disulfide conformers in hair shafts may be linked to the brittleness observed in trichothiodystrophy.

In this study, a novel E583V missense mutation in the hairless gene was identified in an Italian family with atrichia with papular lesions, reinforcing the significance of zinc-finger and LXXLL domains in this condition.

In this study, the novel fatty acid-conjugated tetrapeptide Palmitoyl-GDPH enhanced wound healing in rats by improving re-epithelialization and collagen deposition with minimal toxicity observed at the used dosage.

This study discovered previously unknown structures in human hair shafts that may stabilize hair structurally and physicochemically.

This study identified eight alleles of the caprine KAP13-3 gene in cashmere goats, which could influence gene expression and cashmere fiber characteristics.
