Aims: The underlying mechanisms of vitamin D receptor (VDR) and osteoprotegerin (OPG) genetic variation associated with bone mineral density and osteoporosis remain uncertain. The Taq1 polymorphism is observed in the coding region of the VDR gene and is caused by a single base change C to T in codon 352 at the 3′end of VDR gene. This polymorphism in the translated region is the only one in this study which causes functional and structural variability of the VDR protein and may cause a longer or shorter VDR protein variant [ 54 ]. Previous studies of candidate gene polymorphism and genome wide association studies have concentrated on the relationship between onset of T2DM and VDR gene, but outcomes have often been fickle among different populations. Li, N. Ding, H.-L. Yi The VDR gene maps to a region on chromosome 12 that has been shown to be linked to IBD by genome screening techniques. % FokI CONCLUSIONS: VDR BsmI gene polymorphism is closely related to the susceptibility to hypertension. D receptor polymorphism, hypertension”, and “VDR, hypertension”. The FokI polymorphism is located in the coding region of the VDR gene and results in a VDR protein with a different structure, creating a new start codon and consequently a VDR … In this study, we explored the association between the gene polymorphism of Bsm1 and Fok1 of VDR and sarcopenia, as well as muscle trait. Zhu, Z.-Q. To cite this article. ORs and corresponding 95%CI of eligible studies were calculated using RevMan5.3 and STATA12.0. This study results indicated that the BsmI polymorphism in the VDR gene plays a significant role in protection against prostate cancer and BPH. The pathogenesis of sarcopenia is not clear. 1, Table 2) VDR gene polymorphisms were genotyped for all studied subjects, and the resulted RFLP products were visualized by 3% agarose gel electrophoresis (Fig. (J. Endocrinol. Primers for Fok1 amplified a sequence of about 267 bp in length. This case‐control study included 70 patients with AP and 40 healthy controls. Regarding endocrine characteristics, VDR gene polymorphism has been associated with total testosterone in PCOS and PP populations [8, 13], with estradiol levels in PP girls , and with metabolic abnormalities in different non-PCOS populations [16–23]. Y.-B. 1). Vitamin D receptor (VDR) gene polymorphisms were linked to different cancers. Search nearly 14 million words and phrases in more than 470 language pairs. Free PDF Download. VDR rs1544410 (BsmI) was associated with suscep- In contrast, a chines study found that ApaI genotype of VDR gene polymorphism was linked with T2DM . Common VDR polymorphisms and their associated alleles. Also the relationship between plasma vitamin D levels and frequency of FokI-ff gene polymorphism was significant in all study participants (P = 0.045). RESULTS: Seven independent studies report-ing the association between VDR gene polymor - phisms and hypertension were enrolled. The studies have pointed out allelic variations in VDR gene, such as Cdx 2, Fok 1, Bsm 1, Taq 1, Apa 1 and Poly A in different ethnic groups with breast cancer incidence with contradictory results [ 117 , 118 , 121 , 126 ]. Calcitriol (the active form of vitamin D) binds to VDR, which then forms a heterodimer with the retinoid-X receptor.The VDR heterodimer then enters the nucleus and binds to VDR responsive elements in genomic DNA.VDR binding results in expression or transrepression of specific gene products. Significant association was found between Fok1 and Taq1 Polymorphism of VDR gene in Gujarati Asians living in West London [18, 32]. Most studies on the VDR gene polymorphisms association with breast and renal cancers have focused on seven types of polymorphisms: Fok1 polymorphism in exon II (), Bsm1 and Apa1 in intron VIII, Cdx2 in exon I, Taq1 in exon IX, Tru91 in intron VIII, and the poly(A) () mono-nucleotide repeat in the 3’-untranslated region (3’ … 11 The FokI polymorphism was associated with an increased ovarian cancer risk. The vitamin D receptor (VDR) is a member of the nuclear receptor family of transcription factors. 20: 592-596, 1997) ©1997, Editrice Kurtis BACKGROUND The vitamin D receptor (VDR) gene represents a strong positional candidate susceptibility gene for inflammatory bowel disease (IBD). polymorphism, the absence of the BsmI restriction site was associated with one-third the risk of prostate cancer and with one-half the risk of BPH compared with the male controls. Author summary Present study was carried out to find out the association of vitamin D receptor (VDR) gene polymorphism, mRNA gene expression of VDR gene and level of vitamin D with leprosy reactions and leprosy patients. Regarding endocrine characteristics, VDR gene polymorphism has been associated with total testosterone in PCOS and PP populations [8, 13], with estradiol levels in PP girls , and with metabolic abnormalities in different non-PCOS populations [16,17,18,19,20,21,22,23]. The vitamin D receptor (VDR) gene polymorphism is one of the most widely studied, and has been indicated to be involved in bone mineral homeostasis, bone remodeling and bone matrix composition .

Request PDF | Vitamin D Receptor (VDR) Gene Polymorphism in Patients Diagnosed with Colorectal Cancer | Colorectal cancer (CRC) is one of the most commonly occurring neoplasias in humans. The vitamin D receptor (VDR) encoded for by the gene VDR is the receptor for the bioactive form of vitamin D, calcitriol. This work aimed to assess the impact of different etiologies of acute pancreatitis (AP) and vitamin D receptor (VDR) TaqI rs731236 gene polymorphism on the severity of AP. VDR gene polymorphism genotype and allelic distribution (Fig. VDR gene polymorphism does not ap­ pear to be associated with BMD or bone turnover in Thai postmenopausal women. e one of One of the VDR gene polymorphisms is the Fok-I (rs ) polymorphism, which is located in exon and results in an alternative transcription initiation site, leading to alter the activity of VDR protein. We found a significantly higher frequency of B allele in type 1 … Invest. This study was carried out to assess the possible relation between VDR gene polymorphism and the occurrence of HCC in chronic hepatitis C patients. This study aimed to investigate the association of VDR and OPG gene polymorphism as well as gene–gene interaction and their haplotype combination with the risk of osteoporosis. This study included 102 subjects classified into three groups. Methods. This cross-sectional study investigates whether susceptibility to chronic periodontitis (CP) in a Thai population is associated with VDR polymorphisms. Hepatocellular carcinoma (HCC) is a prevalent malignancy worldwide. Caucasians. e polymorphic Fok-I site in exon results in di erent translation initiation region due to thymine (T) to cytosine (C) substitution. In this study, VDR gene ApaI (rs7975232), BsmI (rs 1544410) and TaqI (rs731236) genotypes were compared in men with osteoporosis and male controls. The association between VDR gene polymorphism and sarcopenia is less reported. Conclusion When the genotype frequencies of VDR gene polymorphisms were analyzed with respect to plasma vitamin D levels, a … We examined the VDR gene Bsm Ι polymorphism in 203 type 1 diabetic patients and 222 controls, and the association between the VDR gene polymorphism and type 1 diabetes and their onset pattern. Osteoporosis affects around 20% of all men and overall mortality in the first year after hip fracture is significantly higher in men than women, yet the genetic basis of osteoporosis is less well studied in males. VDR gene Fok I polymorphism was sized using a ladder (100 bp) and fragments visualized at a gel imaging equipment. Population-based and case-control studies have similarly identified polymorphisms in several candidate genes associated with bone mass or osteoporotic fracture, including VDR ( 6 , 13 , 15 ). We used the PSM method to match the sarcopenia group and control group. % No. It is the cellular receptor for 1,25(OH)2 vitamin D3 (calcitriol) which has a wide range of different regulatory … But no association was observed between TB patients in Tuvinian population and Fok1 Polymorphism of VDR gene . VDR gene polymorphism is associated with the breast cancer risk [117–125] but insufficient data are available to find the relationship with breast cancer risk . The VDR TaqI polymorphism located within exon 9 of the gene affects mRNA stability, therefore regulating VDR protein levels and the biological function of vitamin D. Haplotype analysis investigating the interaction between VDR BsmI, ApaI, and TaqI polymorphisms and bone health strongly associated the BsmI A allele and TaqI C allele with osteoporosis risk. The third VDR gene polymorphism analyzed here was FokI (rs10735810, merged into rs2228570, a change from A to G in exon 2). Vitamin D plays a key role in the absorption of calcium from the gut, which is required for healthy bone formation, muscle, and heart activity as well as numerous other cell functions. No other polymorphism was found in this 297‐bp region around Cdx‐2 polymorphism in the 1e promoter region of the VDR gene according to the sequencing result of these 15 random samples. VDR BsmI, ApaI, and FokI gene polymorphisms have shown to increase the risk of having breast cancer. VDR rs2228570 genotype was associated with lower circulating 25(OH)D concentrations in a pan-European population.Vitamin D genotype did not influence the relationship between vitamin D intake and 25(OH)D concentration. VDR gene polymorphism is responsible in the development of intervertebral disc degeneration. Translation for: 'VDR gene polymorphism' in English->Croatian dictionary. Keywords: allergic rhinitis, gene polymorphism, case–control, vitamin D receptor Conclusion: VDR gene polymorphism is associated with AR, and the AA genotype of rs2228570 is associated with the increased risk of AR in the Chinese population. However, 8sm I VDR polymorphism may have physiologic role in calcium homeostatasis by modulating intestinal cal­ cium absorption. However, their relationship with periodontal disease remains unclear. VDR gene and is caused by T→C transition in exon 2 initiation codon. Polymorphism genotype ApaI of VDR gene showed relationship to the insulin secretion in Bangladeshi population, which are at high risk of T2DM with higher prevalence of hypovitaminosis D. A correlation of Apa I polymorphism with fasting blood glucoselevel and intolerance of glucose was evident among those people who had diabetes symptoms at pre-diagnosis stage. The genotype distribution in the sample from the Rotterdam Study … [28] Surprisingly, level of vitamin D in leprosy patients was not found to be associated with the disease and its manifestations. Table 2 VDR gene polymorphism genotype and allele frequencies in the two study groups SNP MS (n=50) Controls (n=50) Significance OR (95% CI) No. polymorphism of the VDR gene (BsmI) in either both sexes19 or females only.18 Recently, considerable scientific interest has been generated in the association between vitamin D deficiency and myocardial iron overload in patients with beta-thalassemia major.3,4 The proposed patho-genetic mechanism linking vitamin D and cardiac Background: Polymorphisms of the vitamin D receptor (VDR) gene have been implicated in susceptibility to infections and bone-related diseases.
