In this study, researchers identified a unique Arg30stop mutation in the vitamin D receptor gene that causes hereditary vitamin D-resistant rickets in a young French-Canadian boy by truncating the receptor and causing hormone resistance.

This study found that absence of the vitamin D receptor in keratinocytes impairs canonical Wnt signaling and leads to alopecia due to defects in keratinocyte stem cells.

This study validated the VQ-Dermato, the first dermatology-specific quality of life instrument in French, and found it to be reliable, acceptable for routine use, and more responsive than the SF36.

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.

This study described the clinical and genetic features of two Iranian siblings with hereditary vitamin D resistant rickets, identifying a specific VDR gene mutation contributing to their symptoms.

This study found that the absence of unliganded vitamin D receptor significantly impairs cWnt and hedgehog signaling pathways necessary for hair cycle initiation in VDR-null mice.

In this study, researchers found that the "U" allele of the Tru9I variant may be associated with low vitamin D levels and altered VDR gene activity in alopecia areata patients, while the "u" allele might have a protective role against developing the condition.

This article discusses the development and clinical progress of PROTAC technology, particularly focusing on the New Drug Application for vepdegestrant, an estrogen receptor-targeting PROTAC, marking significant advancements in targeted protein degradation therapies.

This study found that lower expression of VDR protein in breast cancer patients is associated with increased bone metastasis and poorer prognosis, making it a significant prognostic factor.

The study's findings on VLDL as a biomarker for hair loss are unreliable.

This study found that conditioned medium from hair dermal papilla cells stimulated fetal bovine aortic endothelial cell growth and migration, suggesting VEGF-like activity in the medium.

This study found that the vitamin D receptor plays a crucial role in hair follicle development in cashmere goats by regulating signaling pathways in dermal papilla cells.

This article reviews the use of dermatoscopy and videodermatoscopy in therapeutic follow-up, noting that videodermatoscopy is a reliable tool despite potential cost issues with high magnifications.

This study found that deleting β-catenin in epidermis-specific VDR knockout mice did not prevent UVB-induced skin tumors, indicating β-catenin does not compensate for VDR's role in tumor suppression.

This study investigated vitamin D receptor expression in normal hair follicles and those affected by alopecia areata, focusing on various markers using immunohistochemical staining.

This study found that combining dermoscopy with reflectance confocal microscopy is more sensitive and specific than using either method alone for assessing vitiligo disease activity and treatment response. Additionally, specific characteristics observed via these techniques correlated with either good or poor treatment outcomes.

In this study, a spayed adult female dog with recurrent vaginitis and cystitis due to bone structures in the vaginal canal was successfully treated with manual removal and medication.

This study found that the absence of the vitamin D receptor disrupts hair follicle structure during the first catagen in mice, linked to increased expression of the hairless gene.

Deep Brain Stimulation helps manage Parkinson's symptoms when medication isn't enough.

This case report diagnosed variegate porphyria in a 33-year-old woman based on significant laboratory abnormalities, but with clinical features resembling porphyria cutanea tarda.

This study found that VEGF significantly promoted hair follicle growth and regeneration in mice with scleroderma.

This study introduced and validated the VESALT, a visual extension of the Severity of Alopecia Tool, finding it offers improved reliability and user-friendliness over SALT by incorporating pattern recognition and broader coverage, including non-scalp regions, in assessing alopecia areata severity.

This case report discusses a patient with VHL-associated paraganglioma, highlighting the importance of genetic testing and monitoring in those with VHL disease, due to high mutation penetrance and associated risks.

This study found that after 24 weeks of DPCP treatment for alopecia areata, there was a significant increase in new capillaries and hair regrowth detectable by videocapillaroscopy.

The authors concluded that VSCAPSI, a videodermoscopy-based assessment tool, provides evidence for early diagnosis, differential diagnosis, follow-up, and screening of scalp psoriasis.

This case report describes a young adult female with late-stage Vogt-Koyanagi-Harada disease featuring panuveitis, retinal detachment, hearing loss, alopecia, and vitiligo, who was successfully treated in a hospital.

This study found a strong positive correlation between vascular endothelial growth factor expression and microvessel density in the hair follicles of Liaoning cashmere goats during different fetal periods.

This study observed that the vitamin D receptor is crucial for hair follicle formation and altering tumor development in the Wnt signaling pathway, suggesting therapeutic potential for vitamin D analogues in related tumors.

In this study, researchers found that the vitamin D receptor plays a crucial role in promoting differentiation and protecting against UVB-induced DNA damage in murine melanocytes, suggesting potential implications for melanoma progression.
