20 / 1000+ resultsresearch Behavioral Characterization of Vitamin D Receptor Knockout Mice
This study found that VDR knockout mice exhibited muscle and motor impairments affecting locomotor behavior, while cognitive functions such as exploration, working memory, and anxiety appeared unaffected.
research Vitamin D Receptor: Key Roles in Bone Mineral Pathophysiology, Molecular Mechanism of Action, and Novel Nutritional Ligands
This study suggests that 1,25-dihydroxyvitamin D(3) and fibroblast growth factor 23 form a crucial axis in regulating phosphate balance, akin to its role in calcium regulation, and explores novel VDR interactions including with curcumin.
research Metabolic And Cellular Analysis Of Alopecia In Vitamin D Receptor Knockout Mice
This study found that alopecia in VDR-null mice persists despite undetectable vitamin D levels, indicating a defect in epithelial-mesenchymal communication due to the absence of ligand-independent receptor function.
research Evaluation of Keratinocyte Proliferation and Differentiation in Vitamin D Receptor Knockout Mice
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.
research Hairless Suppresses Vitamin D Receptor Transactivation in Human Keratinocytes
This study found that Hairless (Hr) acts as a corepressor of the vitamin D receptor (VDR) in human keratinocytes, blocking the action of vitamin D on keratinocyte differentiation.
research Evaluation of Keratinocyte Proliferation and Differentiation in Vitamin D Receptor Knockout Mice
This study suggests that alopecia in vitamin D receptor null mice is due to impaired initiation of the hair cycle rather than defects in keratinocyte proliferation or differentiation.
research Vitamin D Receptor-Mediated Control of Soggy, Wise, and Hairless Gene Expression in Keratinocytes
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.
research Role of Vidarikandadi Kala Basti in a Patient with Vitamin B12 Deficiency: A Case Report
This case report described the use of Vidarikandadi Kala Basti, a Panchakarma procedure, which was associated with improved symptoms and a modest Vitamin B12 increase in a patient with deficiency; however, the authors noted that causality cannot be established, and further controlled studies are needed.
research Ligand-Independent Vitamin D Receptor Actions Essential for Keratinocyte Homeostasis in the Skin
This study showed that vitamin D receptor gene-deficient rats exhibit hair loss and skin abnormalities due to differences in gene and protein expression patterns, while ligand-independent VDR action is crucial for normal hair cycle maintenance and skin formation.
research Vitamin D in Dermatology and Cosmetology
Vitamin D is crucial for skin health and managing skin diseases.
research Proliferation and Differentiation of Cultured Human Keratinocytes Is Modulated by 1,25-Dihydroxyvitamin D3 and Synthetic Vitamin D3 Analogues in a Cell Density-, Calcium-, and Serum-Dependent Manner
This study found that human keratinocytes' sensitivity and response to vitamin D3 analogues vary based on cell density, serum availability, and calcium concentration.
research The Expression of Vitamin D-Upregulated Protein 1 in Skin and Its Interaction with Sciellin in Cultured Keratinocytes
This study suggests that vitamin D-upregulated protein 1 (VDUP1) might play a unique role in regulating the differentiation of epidermal cells.
research Vitamin D Inhibits Captopril-Induced Cell Detachment and Apoptosis in Keratinocytes
This study found that calcitriol protects keratinocytes from the cell detachment and apoptosis caused by captopril exposure.
research Vitamin B12 Activates the Wnt-Pathway in Human Hair Follicle Cells by Induction of Beta-Catenin and Inhibition of Glycogen Synthase Kinase-3 Transcription
This study demonstrated that vitamin B12 may promote hair growth in vitro by modulating intracellular signaling in the wnt-pathway, suggesting potential benefits for micrograft transplantation.
research Knowledge, Attitude and Perceptions of the Population Towards Vitamin D in Jeddah, Saudi Arabia
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.
research Evaluation of Ameliorative Efficiency of Vitamin E and Saccharomyces Cerevisiae Yeast on Arsenic Toxicity in Black Bengal Kids
This study found that supplementing arsenic-fed Black Bengal kids with vitamin E, alone or combined with yeast culture, partially ameliorated growth and reduced arsenic load in faeces, urine, and hair.
research Knowledge, Attitude, and Practices Related to Vitamin D, Zinc, and Ferritin Deficiencies and the Associated Risk of Hair Loss in Jazan, Saudi Arabia
In this study conducted in Jazan, Saudi Arabia, most participants were aware of vitamin D, zinc, and ferritin deficiencies and their link to hair loss, but only about a third practiced daily sun exposure and vitamin supplement use, highlighting a need for improved health education.
research Role of the ABCA4 Gene Expression in the Clearance of Toxic Vitamin A Derivatives in Human Hair Follicle Stem Cells and Keratinocytes
This study investigated the role of the ABCA4 gene in human keratinocytes and hair follicle stem cells and found that silencing the ABCA4 gene increases the harmful effects of all-trans-retinal on hair follicle stem cells.
research Role of Vidarikandadi Kala Basti in a Patient with Vitamin B12 Deficiency: A Case Report
This single patient case report observed that Vidarikandadi Kala Basti, an Ayurvedic Panchakarma procedure, was linked to modest improvements in Vitamin B12 levels and clinical symptoms, but larger studies are needed to determine its potential role in managing Vitamin B12 deficiency.
research Role of Vidarikandadi Kala Basti in a Patient with Vitamin B12 Deficiency: A Case Report
In this case report, a 22-year-old male with Vitamin B12 deficiency showed improved clinical symptoms and a modest rise in Vitamin B12 levels after undergoing classical Panchakarma therapy, though the authors emphasize that causality remains undetermined and further research is necessary.
