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.

This review discusses the potential role of vitamin D deficiency in cardiovascular and renal diseases and suggests that supplemental vitamin D could benefit cardiovascular outcomes, especially in African American and postmenopausal women; it reports no new clinical findings.

This article describes the immunofluorescence tomography method to achieve high-resolution 3-D reconstruction of epithelial tissues and reports no clinical results.

The authors observed that the patterned melanoderma on the hairless scalp of fair-skinned Caucasian men with androgenic alopecia resembled similar patterns seen on facial skin.

This study found that a novel R343H mutation in the vitamin D receptor gene impairs its transcription activity, contributing to hereditary vitamin D-resistant rickets and alopecia in the affected family.

This study suggests that vitamin D treatment may be less effective in reducing thyroid autoimmunity for euthyroid men with early-onset androgenic alopecia compared to other men with autoimmune thyroiditis.

This study analyzed watercress oil and confirmed its phytochemical profile, UV absorption properties, and potential efficacy for hair growth, supporting traditional hot oil applications.

This study identified 374 eQTLs in scalp hair follicles associated with genes involved in metabolic, mitotic, immune processes, and responses to steroid hormones, contributing insights into genetic variation and hair traits.

This article reviews keratosis follicularis squamosa, a keratinizing disorder predominantly found in the Japanese population, but reports no new clinical results.

This study reveals that basement membrane composition and structure in mouse hair follicles are specialized for distinct inter-tissue interactions, with laminin α5 being essential for maintaining these interfaces.

This study found that 2MbisP increases epidermal thickening more rapidly than atRA in rhino mice, while both compounds similarly reduce utricle size.

This study created a detailed spatial atlas of healthy human skin and basal cell carcinoma, revealing a potential hair follicle origin for basal cell carcinoma and expansion of certain mesenchymal cell populations.

This study found that while participants in Jeddah, Saudi Arabia, had good knowledge about Vitamin D and recognized sunlight as a key source, there was inconsistency in their attitudes towards maintaining adequate Vitamin D levels.

This review discusses the potential role of vitamin D supplementation as a therapeutic option for alopecia areata due to its immune-regulating effects and reports no new clinical results.

This study found that vitamin D regulates cholesterol metabolism and may influence prostate cancer development through mechanisms affecting prostate cell growth and sex hormone metabolism.

In this study, researchers observed that dietary vitamin D intake and light exposure play a crucial role in vitamin D metabolism in mice, suggesting similar importance for human health in maintaining optimal vitamin D levels.

This study found that DNA damage in obese women was linked to serum 25-hydroxyvitamin D and hair chromium levels, with higher serum vitamin D associated with less damage and higher chromium with more damage.

This study used integrated single-cell chromatin and transcriptomic analyses in developing mouse skin to uncover gene networks involved in skin lineage specification and identified Mef2c+ upper fibroblasts as potential precursors to certain muscle-like structures, with cross-species findings in human skin.

This study used a 3D live imaging system to map cell dynamics in human hair follicles, revealing patterns of cell movement and division that help explain hair fiber extrusion during hair growth.

This review summarizes the proposed model that describes how different shapes of 1alpha,25(OH)2D3 ligands interact with the vitamin D receptor to mediate genomic and rapid responses in cells.

In this study, researchers found that sesamin, a component of sesamum, modulated the AR-MAPK-Wnt signaling pathway in DHT-stimulated HaCaT keratinocytes, demonstrating potential multi-target activity against molecular events in androgenetic alopecia.

This research observed that, in domestic cats like Maine Coon and Rex breeds, a "piebald" coat color pattern is likely influenced by the Silver locus, although the specific mutations involved are yet to be published.

This case study of a 2-month-old boy with maple syrup urine disease highlights the dangers of restricting branched-chain amino acid intake, as it led to acrodermatitis dysmetabolica-like skin eruptions and hair loss, later resolved with careful dietary adjustments and monitoring.

This article reviews the potential role of vitamin D supplementation as an adjunct to alemtuzumab therapy in multiple sclerosis management, noting its possible benefits for autoimmune comorbidities and patient adherence, but reports no new clinical results.

Researchers found a new area on chromosome 2 linked to a genetic hair loss condition.

This study located a potential genetic link for androgenetic alopecia on chromosome 3q26, marking an early step in identifying new susceptibility genes for male pattern baldness.

This study identified a novel locus for hereditary hypotrichosis simplex on chromosome 13q12.12~12.3 in a four-generation Chinese family.

This study reports that two mouse models of scarring alopecia exhibit similar patterns of hair loss progression despite histological differences in inflammatory cell localization and MHC class I expression.

This study reports that mutations in human L-PGDS affect the entrance and exit of ligands in its binding cavity, suggesting these residues play a role in ligand interaction processes.

This review highlights how single-cell transcriptomics has advanced understanding of tissue regeneration by revealing cellular diversity and key molecular interactions in animal models, despite methodological challenges, suggesting future applications in developing targeted regenerative therapies.
