This study found that keratin K14 expression occurs early in epidermal cell differentiation, while a hair-specific keratin is expressed later in hair matrix cells, suggesting developmental divergence between the two cell types.

This study found that bulge-derived keratinocytes from human follicles were more resistant to differentiation compared to epidermal keratinocytes, possibly due to WIF-1 involvement.

This study found that transgenic expression of Endothelin 3 in mice can maintain a dark pigmentation phenotype independently of Mc1r signaling by regulating melanogenic genes.

The InCISE score is a promising tool for assessing wound healing in head and neck surgery but needs more research for broader use.

New findings on hair keratin, wound healing, and skin blistering were presented.

This study found that Euph E and Euri A showed strong anti-inflammatory activity and modulated cytokine and immune functions in macrophages, related to specific signaling pathways.

This study found that KRT6A expression increases after epidermal barrier disruption, worsening skin inflammation in disease conditions, and suggests that targeting KRT6A could offer a new treatment approach for inflammatory skin diseases linked to epidermal dysfunction.

In this study, ectopic Wnt10b-mediated β-catenin activation in hair follicles resulted in larger regenerating anagen hair structures, an effect modulated by the Wnt inhibitor DKK1.

In this study, PEVIII, a nanocomposite chitosan-coated vesicle containing both α-hederin and hederacoside C, demonstrated notable antibacterial activity against Pseudomonas aeruginosa in a keratitis model, showing significant lesion reduction, tissue improvement, and decreased bacterial load and inflammatory markers compared to other treatments.

This study found that NKIRAS2 expression affects skin tumor suppression and HRAS-driven transformation in mice, indicating its role in carcinogenesis depends on expression level and cellular context.

This study reports that trichocyte intermediate filaments from rat vibrissae and human hair follicles may contain a hollow region at their core, suggesting unique structural properties.

This review highlights the potential of marine macroalgae as a largely untapped resource for developing new active ingredients in the cosmetic industry, emphasizing their role in supporting circular economy models by utilizing waste from other industrial sectors.

This study found that applying the highest dose of biostimulant improved the fresh yield, leaf area, and ACO2 of hydroponically grown ‘Genovese’ basil, suggesting enhanced productivity with reduced fertilizer use.

This study explored social perceptions of men with androgenetic alopecia, finding that increased hair loss was associated with perceptions of being older, less attractive, smaller, and less masculine, but more family-oriented and socially agreeable, highlighting how hair loss influences first impressions.

This study found that increasing hair loss in men was associated with appearing older, less attractive, and less successful, but more family-oriented and likeable, highlighting the influence of hair loss on first impressions.

This study found that K17 is crucial for the structural integrity and survival of hair-producing cells, with K17 null mice developing alopecia due to hair fragility and follicular alterations.

A mutation in the KRT25 gene causes woolly hair and hair loss.

This study suggests that the emulsion extract of brevilin A from Centipeda minima may stimulate hair regrowth in individuals with mild to moderate vertex balding by inhibiting JAK3.

This study suggests that chronic treatment with TPA in mouse skin selectively expands a keratinocyte subpopulation hyperinducible for ODC, which may be a key target for neoplastic transformation.

This study found that a mutation in the seventh exon of the KRT86 gene plays a major role in the pathogenesis of monilethrix in a Chinese family.

This study found that enhanced wound healing in oral mucosa involves a SOX2-regulated transcriptional network which includes increased expression of keratin K75, and interaction of K75 with the LINC complex may play a crucial role in promoting rapid wound repair.

This study found that mice with a mutation in the Zdhhc13 gene exhibited increased susceptibility to skin cancer, highlighting a potential protective role of palmitoyl acyltransferase in skin carcinogenesis.

This study demonstrates that canonical Wnt signaling is crucial for maintaining thymic epithelial microenvironments in postnatal thymus, possibly by affecting TEC progenitor cells.

This study found that the mK6alpha and mK6beta genes in mice are regulated differently at the mRNA level, with implications for understanding K6 gene evolution and function in mammals.

This study reports a semidominant inheritance of epidermolytic ichthyosis due to a KRT1 mutation, which was previously thought to be only inherited dominantly.

K39 and K40 are the last keratins expressed in hair development, completing the hair keratin catalog.
