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.

This study found that intracrine androgen signaling via 5α-reductase is essential for optimal endometrial decidualization and vascular development during this process in mice.

This review examines the role of vitamin D and its receptor in skin functions, exploring mechanisms regulating proliferation, differentiation, immunity, and tumor suppression, without reporting new research findings.

In this study, the researchers found that alopecia in VDR null mice is likely due to issues with hair cycle initiation rather than defects in keratinocyte proliferation or differentiation.

In this study, prenatal ultrasonography was found to be a valuable tool for screening ectodermal dysplasia during pregnancy, and a new EDA gene variant associated with X-linked hypohidrotic ectodermal dysplasia was identified, aiding in more accurate diagnoses and reproductive decision-making.

This case study described a girl with vitamin D-dependent rickets type 2A who developed long-standing tertiary hyperparathyroidism, yet this did not hinder the healing of her rickets or normalization of hypophosphatemia; high doses of intravenous calcium were pivotal for recovery.

This study examined the correlation between vitamin D, its receptor, and chronic telogen effluvium in females, identifying possible links between these factors and increased hair shedding.

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 review discusses how the HSD3B1(1245C) genotype may impact androgen physiology and the progression of castration-resistant prostate cancer, and does not report new experimental results.

This study reports that the transgenic expression of Dsg1 in mice rescued the severe B6-Dsg3−/− phenotype and created a syngeneic mouse model of pemphigus vulgaris, which may aid in understanding autoimmunity mechanisms.

This study found that actively targeted AN2728-loaded nanocarriers reduced inflammation and improved skin condition in a mouse model of psoriasiform inflammation compared to free drug and non-targeted nanoparticles.

This study found that distinct isoenzymes of 3 beta-hydroxysteroid dehydrogenase are expressed in human adrenals and gonads compared to the placenta and skin.

This study identifies two new proteins, CCDC22 and CCDC93, essential for root and root hair growth in Arabidopsis, and demonstrates their genetic link to a VTI13-dependent vacuolar trafficking pathway.

This study found that relatively low concentrations of 1,25(OH)2D3 stimulated human hair follicle and fiber growth, while higher concentrations inhibited growth in a whole-organ culture system.

In this study, the analysis of Ukraine's pharmaceutical market from 2020 to 2023 found a large variety of Vitamin D3 preparations, predominantly domestic and synthetic, with capsule forms being common; consumer surveys highlighted that doctor recommendations strongly influenced purchasing decisions.

This study found that vitamin D receptor mutations lead to hair follicle alopecia due to impaired cyclic regeneration, which is distinct from vitamin D receptor effects on epidermal keratinocytes that largely depend on 1,25-dihydroxyvitamin D.

This study developed a pemphigus model in mice showing that anti-Desmocollin 3 and anti-Desmoglein 3 antibodies lead to more severe disease, suggesting diverse antigens contribute to varying human pemphigus phenotypes.

This study suggests that the DNMT3B -579 G>T polymorphism may be a genetic risk factor for colorectal cancer in the Azerbaijani population.

This study found that the Antera 3D® system provided an objective and sensitive method for assessing pediatric pathological scars, capturing significant changes in pigmentation, vascularity, and volume, compared to the traditional Vancouver Scar Scale and dermoscopy, which showed varied sensitivities across different scar parameters.

This study found that videodermoscopy can help diagnose nailbed psoriasis by revealing distinctive hyponychial capillary patterns, which correlated with disease severity and response to treatment.

This commentary explores the potential of 1α,25-dihydroxyvitamin D3 in enhancing hair regeneration by affecting dermal papilla cells, but reports no new experimental findings.

This study found that a new three-dimensional high-frequency ultrasound (3D-HFUS) can successfully visualize skin tumors and inflammatory hair diseases, offering promising noninvasive diagnostic and evaluation capabilities compared to traditional two-dimensional methods.

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, researchers found that a PER3 gene SNP may be pathogenic for a new subtype of dyschromatosis universalis hereditaria, especially when combined with a SASH1 mutation.

This study found that ultraviolet light-enhanced visualization can detect subtle skin changes linked to carotene and vitamin A deficiency, which improved with dietary correction in deficient individuals.

This case report presents the dental challenges faced by a child with vitamin D-dependent rickets type II, including early onset rickets, alopecia, and specific dental abnormalities, emphasizing the need for comprehensive, multidisciplinary management.

This review discusses the development and findings of 3D human skin models for studying melanocyte homeostasis and melanoma progression but reports no new clinical results.

This study suggests no significant association between vitamin D receptor gene polymorphisms and alopecia areata.
