In this study, the researchers found that vitamin D and calcium signaling in keratinocytes are essential for normal skin regeneration after wounding, with deficiencies significantly delaying wound closure and re-epithelialization in mice.

In this study using genetic mouse models, researchers discovered that senescent melanocytes in nevi secrete osteopontin, which activates hair stem cells, enhancing hair growth; this process is mirrored in human hairy nevi, suggesting a potential therapeutic target for regenerative disorders.

This study identified 12 new genes associated with the hair follicle and various stages of the hair cycle in mice, which could lead to novel targets for hair growth or depilation therapies.

The authors concluded that intralesional triamcinolone acetonide may benefit patients with patch-type alopecia areata, but the evidence is limited due to small, bias-prone studies with variations in treatment protocols.

This study found that the GGC repeat length significantly influenced testosterone levels in oral contraceptive users from high-risk breast cancer families, and homozygosity for short alleles may be linked to increased breast cancer risk.

This study identified a novel gene, hacl-1, that is specifically expressed in the hair follicles of ICR mouse skin and is associated with their active state.

This review discusses the interactions between melanocyte stem cells and their niche in hair regeneration and repair, but reports no new results; recent studies on molecular pathways are highlighted.

This study reports that compound heterozygous loss-of-function mutations in the HEPHL1 gene in a child were associated with abnormal hair and cognitive issues, linking altered ferroxidase activity to hair disorders.

In this study, mutations in the vitamin D receptor were identified in Brazilian children with rickets and alopecia, leading to impaired receptor activation and reduced 24-hydroxylase expression.

Researchers found an RNA transcript that might help control a growth factor linked to tumor development.

In this case report, researchers identified Arthroderma vanbreuseghemii as the cause of a familial fungal infection, which was successfully treated with itraconazole and topical terbinafine cream.

This review explores how low-energy He-Ne laser therapy may stimulate repigmentation in vitiligo by affecting mitochondrial pathways and melanocyte function, but does not report new clinical results.

Method quickly measures finasteride concentration in capsules.

This review discusses the migration and colonization of melanocytes from the neural crest in mammals and reports no new experimental results.

In this study, overexpression of Wnt5a in mice was associated with the elongation of the telogen stage and inhibition of hair growth initiation, suggesting Wnt5a's role in maintaining hair follicle quiescence.

This study found that the methanolic heartwood extract of Avicennia marina significantly inhibits 5α-reductase type 1, reducing 5α-DHT production by 52% in a cell-based assay with human hair dermal papilla cells.

This study concluded that neither basal nor ACTH-stimulated 17-OHP concentrations effectively indicate carrier status for 21-hydroxylase deficiency among Slovenian hyperandrogenic women, recommending molecular analysis of the CYP21 gene for reliable screening.

In this study, researchers identified specific long non-coding RNAs involved in feather development that do not follow traditional genetic inheritance patterns in chickens.

This study found that manipulating AKR1D1 expression in human liver cells effectively regulates glucocorticoid clearance and receptor activation, highlighting its role in liver-specific steroid hormone regulation.

This review highlights the traditional use and potential therapeutic activities of Asiasari Radix in drug discovery, but it reports no new clinical results.

This study found that Avicennia marina extract significantly inhibited 5α-reductase type 1 activity in human hair dermal papilla cells, suggesting its potential use for treating androgenic alopecia.

This review discusses various aspects of hair color, including its formation and evolutionary variations, based on research presented at the 4th Intercontinental Meeting of Hair Research Societies 2004, without providing new experimental results.

This study identified a new gene, mrp4, in mice, which suggests it may have a unique role in the growth and development of hair follicles in the ears and tails.

This article discusses strategies for changing hair color by regulating target genes in hair follicles using advanced delivery systems, but it reports no new experimental findings.

In this study, adipose tissue secretome was shown to enhance oxidative stress resistance and promote cell proliferation in vitiligo cells, suggesting a potential natural treatment approach.

This study found that transgenic mice overexpressing HGF/SF are more susceptible to UVA-induced melanoma, with melanin in the papillary dermis interacting with UVA to induce melanoma.

This study used single-cell RNA sequencing to create a detailed atlas of human scalp hair follicles and found that early-stage hair graying involves matrix hair progenitor depletion linked to P53 pathway activation.

This study suggests that 3,4,5-tri-O-caffeoylquinic acid activates β-catenin to enhance pigmentation in mouse hair follicles, human melanocytes, and melanoma cells during the hair cycle's growth phase.

In this study, researchers identified a new dominant mutation in Hairless mice, called Pied, resulting from a deletion in the Adam10 gene, which causes freckle-like skin pigmentation by inhibiting melanocyte expansion.

This study found that the vitamin D receptor, but not its ligand, regulates genes involved in hair cycle progression, suggesting a role in integrating hormone signaling pathways for hair and epidermal functions.
