This case report documents the first known instance of FOXN1 duplication linked to congenital hypertrichosis.

In this study, researchers used an evolutionary-rate-based method to identify genetic elements associated with reduced hair in mammals, finding a dichotomy between accelerated coding sequences and noncoding regulatory elements influencing hair growth.

This study identified new genetic variants on chromosome 20p11 associated with male pattern baldness.

This review proposes a theoretical model for treating androgenetic alopecia using STEAP3 protein, based on recent findings about genetic mutations affecting molecular pathways, but emphasizes that this hypothesis needs validation through laboratory and clinical studies.

This study examined 16 sporadic trichoblastic tumors and found that although one showed malignant transformation, clinical follow-up revealed no residual or metastatic disease. RNA sequencing indicated a high tumor mutational burden and absence of a UV-related signature, helping to distinguish these tumors from similar growths.

In this study, researchers found that mice lacking the transcription factor FOXC1 in their hair follicle stem cells had increased rounds of hair regeneration but experienced hair thinning due to impaired ability to maintain stem cell quiescence and adhesion.

This research found that melatonin has a bidirectional effect on hair follicle stem cell survival, improving it at low doses and inhibiting it at high doses.

In this study, researchers identified four gene variants that may contribute to androgenic alopecia and vitiligo, proposing a novel di-genic inheritance model that could help guide genomic approaches for personalized treatment and early diagnosis.

This study explored the molecular mechanisms determining the identity of keratinocytes and corneal epithelial cells, finding that miRNAs from the Gtl2-Dio3 region, which regulate key signaling pathways, play a significant role in cell identity through the Hox/Gtl2-Dio3 miRNA axis.

This study examined the role of long non-coding RNAs in wool fineness among Gansu alpine fine-wool sheep, identifying specific lncRNAs and target genes that may enhance wool quality.

This study reviewed early research on topical finasteride for androgenetic alopecia, finding it appears safe and promising, though further investigation is needed to determine optimal dosing, frequency, and potential applications for other types of alopecia.

This study concluded that KLF4 is a crucial regulator of hair follicle stem cell quiescence and may work by interacting with multiple transcription factors to control related genes.

This study found that transplanted hair follicle-associated pluripotent stem cells in mice differentiated into keratinocytes and stimulated hair growth by producing mature hair shafts.

This study developed a foxn1-deficient Xenopus laevis model using CRISPR/Cas9, observing reduced T-cell markers and altered immune responses in tadpoles, providing a nonmammalian model for immunological research.

This article reviews the history and characteristics of the rare nude phenotype SCID, primarily distinguished by severe T cell immunodeficiency and notable skin and hair abnormalities, but reports no new clinical findings.

This study found that skin bacteria promote regeneration in wound-induced hair follicle neogenesis, suggesting a role for IL-1β signaling and challenging the belief that infection inhibits healing.

This study found that the absence of Hif-p4h-2 in specific mouse skin cells disrupted hair follicle development, leading to hair loss due to irregular keratin formation and pathway signaling.

This study identified that patients with compound heterozygous mutations in FOXN1 exhibited severe T-cell lymphopenia but retained normal hair and nail development, indicating a distinct clinical phenotype from classic FOXN1 cases.

This study reported that patients with specific Foxn1 mutations exhibited severe T-cell lymphopenia without the hair and nail abnormalities usually associated with these mutations.

This research found that Foxc1 promotes quiescence in hair follicle stem cells and identified COL17A1 depletion, due to DNA damage, as a cause of hair thinning and loss during aging.

This research found that Foxc1 is critical for maintaining quiescence in activated hair follicle stem cells and that the cancer cell-of-origin influences tumor heterogeneity in mouse skin squamous cell carcinoma.

This review discusses recent genome-wide association studies identifying novel candidate genes for various forms of alopecia, providing insights into their pathogenesis and molecular mechanisms, but reports no new clinical results.

This study identified interactions between EGF signaling and the GLI proteins in basal cell carcinoma that may contribute to the limited metastasis seen in this skin cancer.

In this study, the Foxn1(-/-) nude phenotype was associated with an altered regulation of epithelial progeny in skin, offering a valuable model for investigating stem cell niche maintenance and regulation.

Six new genes linked to early hair loss were found, which also surprisingly connect to Parkinson's disease and lower fertility.

Six new genes linked to early hair loss were found, which also surprisingly connect to Parkinson's disease and lower fertility.

Six new risk spots for early hair loss were found, which also link to Parkinson's disease and lower fertility. Two genes, FOXA2 and HDAC4, could be new treatment targets. Hair loss might also be connected to heart disease, metabolic syndrome, and prostate cancer.

In this mouse study, researchers found that the absence of laminin-511 in skin delays hair follicle development and disrupts hair shaft differentiation, affecting key transcription factors for hair keratins.

This study found that micro-current electrical stimulation may promote hair growth in human hair follicle-derived papilla cells and a mice model by enhancing cell proliferation, migration, and activating key growth pathways.

This study reported that in mice with rapamycin-induced thymic atrophy, Angelica sinensis promoted thymic cortical regeneration and functional recovery by activating the Wnt/CTNNB1/Foxn1 signaling pathway and improving inflammatory microenvironment, suggesting its potential benefit against immune aging.
