This study found that Wnt ligands secreted by the hair follicle epithelium are crucial for hair follicle regeneration in adults and could inform treatments for hair disorders like alopecia.

This study found that hair germ and epidermal basal cells differ in keratin expressions in rat hair tissues, with hair-specific keratins appearing after the differentiation of each layer.

This review discusses the role of TGM3 in skin and hair follicle biology, human tumor pathology, and genetic abnormalities, and reports no novel results; the authors highlight its potential as a cancer diagnostic biomarker.

In this study, researchers found that the histone demethylase UTX is crucial for regulating skin differentiation through retinoic acid signaling, mainly impacting females, as males compensate with a Y-linked paralog.

This review discusses the biological roles and diagnostic significance of keratins in mammalian colon epithelial cells and reports no new clinical results.

This study found that TPA induces apoptosis in pig renal epithelial cells by affecting cell cycle proteins, and activated ras can prevent this process.

Topical thyroid hormones may boost hair growth.

In this study, Nε-(carboxymethyl) lysine was found to weaken hair follicle morphogenesis and inhibit essential cell activities in a model simulating accumulated glycation.

This study concluded that bone morphogenetic proteins are crucial for hair follicle stem cell differentiation and that their downregulation by androgens may contribute to the development of androgenetic alopecia.

This study observed that CIP/KIP proteins play a significant role in regulating cell cycle arrest and differentiation in human hair follicles, supporting hair growth and formation in the anagen phase.

This study found that the SVpgC2a keratinocyte cell line, used as a model for dysplastic epithelium, showed increased apoptosis, proliferation, and aberrant keratin expression compared to normal keratinocytes from buccal mucosa.

This study found that chitosan nanoparticles containing Cordyceps militaris effectively reduced lung damage in mice exposed to fine particulate matter (PM2.5) by decreasing oxidative stress and preserving lung barrier integrity, suggesting potential as a therapeutic candidate for PM2.5-induced lung diseases.

This study reported that Cosmos caudatus extract alone may therapeutically modulate the AR–FGF-2 axis in a BPH rat model, comparable to finasteride, but combining them disrupted pathway regulation, increasing TGF-β levels.

Keratin 79 cells help form and regenerate hair canals.

In this study, researchers found that TSPyV T antigens can disrupt normal cell differentiation and proliferation in hair follicles and interfollicular epidermis, possibly contributing to trichodysplasia spinulosa pathology.

This study identified that mouse MILL1 and MILL2 are glycoproteins distinct from human MICA/B, primarily due to their association with β2-microglobulin and TAP-independent surface expression.

This study found that hoof progenitor cells from fresh equine tissue have multilineage differentiation capabilities, offering insights for future progenitor cell-based hoof and dermal-epidermal tissue engineering.

MCSP may help identify and regulate skin stem cells, affecting hair growth and regeneration.

In this study, physiological levels of free T3 significantly enhanced the survival of human hair follicles in vitro.

This study found that epithelial keratin K 6 is associated with hyperkeratotic and ulcerated changes in the gastric pars oesophagea of pigs, suggesting epithelial proliferation plays a role in ulcer development.

This study found that specific human hair keratins are differentially expressed in the hair follicle, suggesting a shared pathway of epithelial differentiation between hair cortex and nail plate cells.

This study found that beard hair medulla cells express an unexpected range of keratins, showing variability and promiscuous behavior in keratin interactions distinct from other hair follicle cells.

In this study, researchers found that DNMT1-mediated methylation of SRD5A2 in urethral epithelial cells from hypospadias-afflicted rats upregulates proteins associated with cell cycle and mitochondrial function, suggesting SRD5A2 as a potential therapeutic target for hypospadias due to its role in modulating cellular functions.

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 found that both epithelial and hair keratins are expressed in beard hair medulla cells, exhibiting unique patterns and interactions distinct from other hair follicle and epithelial cells.

This study found that different bovine epithelial tissues express varying types of cytokeratins, with hair follicle and nasolabial gland expressing both acidic and basic types, while others express only one or the other.

This study found that keratin K80, structurally similar to hair keratins, is broadly expressed in various epithelial tissues and is involved in intermediate filament formation with multiple type I partners.

This study found that Neuregulin3 can influence the development and differentiation of mammary glands and epidermal features in mice, potentially by inducing c-Myc and altering cell proliferation and adhesion.

This review discusses the role of keratins in maintaining epidermal structure and function and reports no new results; the authors emphasize the lack of rational therapies for skin disorders linked to keratin mutations.

This study found that, in mouse tail epidermis, stem cells rapidly activate and regenerate new progenitors to repair wounds, with mechanisms affecting their proliferation, differentiation, and migration.
