GNPTAB gene is crucial for normal hair color in humans and mice.

This study identified overexpression of certain immune-related genes and underexpression of genes in specific signaling pathways in premature androgenetic alopecia, suggesting potential new therapeutic targets.

This review discusses the current status of genetic research on male-pattern hair loss and reports no new findings, outlining significant achievements and future challenges in understanding its biology and treatment.

This review discusses the potential markers for identifying and studying stem cells in the epidermis and hair follicles, highlighting their role in understanding skin disease pathogenesis and expanding therapeutic options, but reports no new findings.

Hair graying is caused by the loss of pigment cells due to poor maintenance of stem cells in the hair follicle.

In this study, the expression of certain hair follicle-related genes differed between growth phases in Angora goats, with HOXC13 showing overexpression during the anagen phase, potentially influencing the mohair's shine and texture.

This study explored gene expression in Changthangi goats and found that higher expression of keratin-related genes and specific signaling pathways may play a role in the development of Pashmina fiber.

This study found that among men over 70, certain genetic variants associated with skin pigmentation affect serum PSA levels, with implications for how sun sensitivity and exposure may influence prostate cancer risk.

This review examined and discussed the role of dermis-derived factors in the regulation of melanogenesis, noting their significance in both normal and abnormal mammalian skin conditions, suggesting an underexplored area of study compared to dermal and epidermal influences.

This study found that compromised antioxidant activity in gray hair follicles affects both mature melanocytes and their immature precursors, linked to down-regulation of melanogenesis-related genes.

This study identified molecular differences between dysplastic nevi and common melanocytic nevi, including altered keratinocyte differentiation, increased hair follicle-related molecule expression, and distinct immune microenvironment characteristics in dysplastic nevi.

This study analyzed gene expression changes during the autumn coat color change in mountain hares and found conserved gene regulation with snowshoe hares, highlighting its role in seasonal camouflage adaptation.

This review discusses the role of autophagy in skin cells and its potential implications for treating immune-related skin diseases, reporting no new clinical results.

This study examined the factors contributing to gray hair, such as genetics and lifestyle, and found that while graying correlates with some health conditions, it is primarily a physiological process rather than a pathological one.

This study found that CD34- melanocyte stem cells regenerated pigmentation more efficiently, while CD34+ cells showed potential for neuron myelination, suggesting different therapeutic applications for each population.

In this study, modulating Tyrosinase expression altered mouse coat color by affecting melanosome accumulation, indicating that melanosome maturity plays a role in determining skin and hair color beyond total melanin content.

This study observed that serotonin signaling promoted hair shaft elongation and upregulated hair growth-related genes in dermal papilla cells, suggesting its potential role in advancing alopecia therapy.

This study found that differences in skin transcriptomes between juvenile and adult mink, as well as between black and white mink, suggest genes regulating hair color are active during early development rather than adulthood.

This study found that the alcohol extract of Vernonia anthelmintica may counteract stress-induced hair follicle growth inhibition in mice, potentially offering a new approach for treating stress-related hair loss.

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.

This study found that a laboratory model using nude mice can produce human hair follicles with amino acid compositions resembling both normal and trichothiodystrophy-affected human scalp hair over extended periods.

This study found that a noncrosslinked hyaluronic acid filler restored cell viability against UVB-induced cytotoxicity and increased VEGF secretion in human dermal papilla cells, suggesting potential for mesotherapy use after further research.

This study explored the diversity of melanocyte stem cell subpopulations in the hair follicles of adult female mice and identified novel groups with distinct immune privilege regulation, suggesting a heterogeneous landscape that future research should consider.

In this study, researchers developed WS Biotin, a new water-soluble form of biotin, and found that it significantly improves water solubility compared to free biotin and enhances hair-related keratin expression, gene activity for hair growth in vitro, while also reducing melanin content in skin cells.

This review discusses the biology of hair follicles across various species and their role in fiber quality, but reports no new experimental findings.

In this study, researchers identified three pathogenic de novo genetic variants contributing to epidermolysis bullosa simplex in young children, highlighting the complexity of genetic influences and underscoring the need for early genetic screening for accurate diagnosis and effective management.

This review addresses obesity-related dermatoses and highlights the potential increased risk of skin cancer associated with obesity; it presents no new clinical findings.

This study reported that pathways related to apoptosis, cell proliferation, and WNT signaling might be key drivers of hair loss in androgenetic alopecia, guiding potential targets for therapy development.

In this study, researchers found that specific miRNAs may regulate cashmere fiber traits in goats by targeting genes related to hair follicle activities, with significant expression differences between breeds.

This review discusses factors influencing hair pigmentation and the etiology of canities, noting the lack of clarity in underlying mechanisms and calling for further research on treatment options.
