ANG II type 1 receptor blockade (AT1R-BLK) is used extensively to slow down the progression of proteinuric kidney diseases. We hypothesized that AT1R-BLK provides podocyte protection through regulation of silencing mediator of retinoic acid and thyroid hormone receptor (SMRT) and vitamin D receptor (VDR) expression under adverse milieus such as high glucose and human immunodeficiency virus infe...
Hereditary 1,25-dihydroxyvitamin D-resistant rickets (HVDRR) is caused by mutations in the VDR gene, and its inheritance is autosomal recessive. In this report, we aimed to confirm whether HVDRR is occasionally inherited as a dominant trait. An 18-month-old Japanese boy was evaluated for short stature and bowlegs. His father had been treated for rickets during childhood, and his paternal grandf...
Aberrant activation of the Wnt/β-catenin pathway is critical for the initiation and progression of most colon cancers. This activation provokes the accumulation of nuclear β-catenin and the induction of its target genes. Apc(min/+) mice are the most commonly used model for colon cancer. They harbor a mutated Apc allele and develop intestinal adenomas and carcinomas during the first months of li...
BACKGROUND Vitamin D can translocate a vitamin D receptor (VDR) from the nucleus to the cell membranes. The meaning of this translocation is not elucidated in terms of a role in pathogenesis of chronic obstructive pulmonary disease (COPD) till now. VDR deficient mice are prone to develop emphysema, suggesting that abnormal function of VDR might influence a generation of COPD. The blood levels o...
507 Abstract: The vitamin D receptor (VDR), a member of the nuclear receptor superfamily, is an integral part of the body’s calcium regulatory system. Mammalian and avian VDR genes were isolated, sequenced and characterized. In this study we cloned the vitamin D receptor from amphibians. We received a cDNA library prepared from amphibian (frog) tissues and prepared a cDNA probe based on the avi...
The vitamin D receptor (VDR) is a ligand-inducible transcription factor whose target genes play key roles in cellular metabolism, bone formation, cellular growth, differentiation and in controlling inflammation. Many of these VDR target genes are also involved in dysregulated pathways leading to common human diseases, such as cancer. The activation of VDR by natural and synthetic ligands may im...
Objective. It has been stated that brain cancers are an increasingly serious issue in many parts of the world. The aim of our study was to determine a possible relationship between Vitamin D receptor (VDR) gene polymorphisms and the risk of glioma and meningioma. Methods. We investigated the VDR Taq-I and VDR Fok-I gene polymorphisms in 100 brain cancer patients (including 44 meningioma cases a...
PURPOSE Vitamin D receptor (VDR) polymorphisms are considered to be risk factors for prostate cancer. However, previous case-control studies on the association between the variants of VDR and prostate cancer have shown contradictory results. Therefore, the role of VDR in prostate cancer remains unresolved. To investigate a potential correlation between VDR polymorphisms and prostate cancer risk...
The Vitamin D receptor (VDR) expressed in normal breast tissue and breast tumors has been suggested as a new prognostic biomarker in breast cancer (BC). Besides, increasing evidence supports the view that the detection of circulating tumor cells (CTCs) predicts outcome in early and metastatic BC. Consequently, an evaluation of VDR expression in the CTCs of BC patients may allow optimization of ...
The vitamin D receptor (VDR) is a nuclear transcription factor responsible for mediating the biological activities of 1,25-dihydroxyvitamin D(3) [1,25(OH)(2)D(3)]. Renal and parathyroid gland VDR content is an important factor in calcium homeostasis, vitamin D metabolism, and the treatment of secondary hyperparathyroidism and renal osteodystrophy. In these tissues, VDR expression is highly regu...
