Mounting evidences support that vitamin D insufficiency or deficiency is a risk factor of breast cancer. Vitamin D receptor (VDR) is expressed in more than 36 cell types in different organs as in cancerous cells. Numerous allelic variants of VDR gene have been identified in human populations. Association of FokI (rs2228570) and BsmI (rs1544410) single nucleotide polymorphisms (SNPs) in VDR gene with the risk of breast cancer have been investigated in several studies, however, the published data are still inconsistent...

BACKGROUND: The association between vitamin D receptor (VDR) gene polymorphisms and multiple sclerosis (MS) has been extensively studied, but results were controversial. METHODS: This meta-analysis aimed to confirm whether VDR gene polymorphisms were associated with MS. Meta-analysis on the association between MS and VDR ApaI, BsmI, TaqI and FokI polymorphisms were conducted using allelic contrast, recessive, homozygotes and dominant models. Data were extracted by standardized forms and odds ratios (OR) with 95% confidence intervals (CI) were calculated using the random effects model if the results were heterogeneous...

Objective: The influence of vitamin D receptor (VDR) genetic variation on serum 25-hydroxyvitamin D levels [25(OH)D] after vitamin D3 supplementation remains unclear. We aimed to investigate changes of 25(OH)D in a randomized, double-blind, placebo-controlled clinical trial, according to VDR genotype, after provision of vitamin D3 to breast cancer cases for a 2-month period. Methods: Participants were assigned to two treatment arms: placebo (n = 28) and vitamin D3 supplementation (n =28). The supplementation group received 50,000 IU of vitamin D every week for 2 months...

BACKGROUND: Vitamin D mediates its action via vitamin D receptor (VDR) and is involved in a wide variety of biological processes including regulation of cell proliferation and differentiation in normal tissue and apoptosis, and cell adhesion in tumor cells. The study of genetic variations in VDR may elucidate the association of vitamin D levels, its metabolism, and VDR polymorphism with various diseases and cancer. The association of VDR polymorphism with cancer has been reported; however, the literature lacks critical analyses of the studies in last 3 years...

Although many epidemiology studies have evaluated the correlation between vitamin D receptor (VDR) BsmI polymorphism and osteoporosis, the current results remain inconclusive. This meta-analysis updated and reevaluated the possible association between VDR BsmI polymorphism and osteoporosis in Chinese populations. Studies were identified using PubMed and Chinese databases through December 2016. The associations were assessed with pooled odds ratios (ORs) and 95% confidence intervals (CIs). A total of nine studies with 688 osteoporosis cases and 730 controls were included in this meta-analysis...

BACKGROUND: In the present study, we explored the link between vitamin D receptor (VDR) BsmI, TaqI, ApaI and FokI gene polymorphisms with deciduous tooth decay in Chinese children. METHODS: Our study included 380 Chinese children aged 4-7 years, whose DNA sample was collected from the buccal mucosa. VDR gene polymorphisms was determined by PCR-RFLP. RESULTS: The adjusted logistic regression analysis demonstrated that BsmI containing the Bb genotype was linked with the increased risk of deciduous tooth decay (OR = 1...

BACKGROUND: The metabolism of vitamin D is complex, its receptor (VDR) and proteins encoded by the genes CYP27B2 and CYP24A1 can influence vitamin D serum levels. The aim of this study was to investigate the relationship of the polymorphisms of VDR (ApaI and BsmI), CYP27B1 and CYP24A1 with serum vitamin D levels in both forms, 25(OH)D3 (circulating form) and 1,25(OH)2D3 (active form), in colorectal cancer (CRC) patients. METHODS: One hundred fifty-two CRC patients and 321 controls were included...

PURPOSE: Preterm birth (PTB) is a complex trait with strong genetic background, whose etiology is not fully understood. It was recently suggested that pregnancy duration is affected by fetal genetic variation even more than by the maternal genome. Vitamin D receptor (VDR) is involved in embryonic implantation and fertility. We studied the association between both maternal and neonatal vitamin D receptor (VDR) genetic variation and PTB. METHODS: Maternal and fetal (umbilical cord) DNA was isolated from Jewish Israeli idiopathic preterm newborns (24-36 weeks, n = 146) and control term newborns (>37 weeks, n = 229)...

BsmI (rs1544410) polymorphism located in intron 8 at the 3'-end of the vitamin D receptor (VDR) gene is known to be involved in the regulation of mRNA stability. Many studies evaluated the possible correlation between VDR BsmI polymorphism and the risk of pulmonary tuberculosis (PTB), and reported conflicting results. In the present study, an updated meta-analysis was performed to evaluate the above-said association. PubMed, Embase, and Google Scholar web-databases were searched for the relevant studies and a meta-analysis was performed by calculating pooled odds ratios (ORs) and 95% confidence intervals (95% CIs) for all the genetic models...

INTRODUCTION: Systemic lupus erythematosus is an autoimmune disease in which the severity varies according to race, sex and age of onset. This variation is also observed in the genetic markers associated with the disease, including PTPN22, VDR and TNF genes. The genetic stratification in different populations worldwide can influence the variability. OBJECTIVE: To analyze the heritability of PTPN22, VDR and TNF genetic variants and their association with pediatric lupus nephritis in Colombian families...

BACKGROUND: Vitamin D and the vitamin D receptor (VDR) are important in the metabolic processes that affect bone mineral density (BMD). However, the effect of VDR BsmI polymorphism on BMD in pediatric patients is still unclear. METHODS: Eligible studies were identified from the following electronic databases: PubMed, Embase, the Cochrane Library, and the Chinese CNKI and Wanfang databases before October 1, 2016. Data were extracted from the eligible studies, and associations between VDR BsmI polymorphism and BMD in pediatric patients were estimated with weighted mean differences (WMDs) and 95% confidence intervals (CIs)...

OBJECTIVES: The vitamin D receptor (VDR) is a member of the nuclear receptor family of transcription factors. We examined whether degree of VDR gene methylation acts as a molecular adaptation to light exposure. We explored this in the context of photoperiod at conception, recent UV irradiance at 305 nm, and gene-latitude effects. METHODS: Eighty subjects were examined for VDR gene-CpG island methylation density. VDR gene variants were also examined by PCR-RFLP. RESULTS: Photoperiod at conception was significantly positively related to VDR methylation density, explaining 17% of the variance in methylation (r(2)  = 0...

BACKGROUND: Polymorphisms of vitamin D receptor (VDR) contribute to the pathogenesis of multiple autoimmune conditions. METHODS: We investigated the incidence of VDR polymorphisms (rs1544410-BsmI; rs7975232-ApaI; rs731236-TaqI) in a group of patients with primary sclerosing cholangitis (PSC, n = 275) and in healthy controls (n = 376). Additionally, correlations of the VDR polymorphisms with clinical and biochemical factors of the disease were analysed. RESULTS: The genotype and allele distributions of these polymorphisms in PSC patients were similar to those observed in controls...

BACKGROUND: Multiple sclerosis (MS) is the most prevalent autoimmune inflammatory demyelinating disease of the central nervous system (CNS) in young adults. More than 50 genomic regions have been associated with MS susceptibility. Due the important immune-modulating properties of Vitamin D, Vitamin D receptor (VDR) gene polymorphisms - which interfere with the actions of Vitamin D- could be related to increased risk of MS. METHODS: We studied 120 patients fulfilling the McDonald criteria for MS (81 females and 39 males) and 180 healthy unrelated controls, nested in a case-Control study, and were recruited from the National Institute of Neurology and Neurosurgery, Manuel Velasco Suárez in Mexico City...
