AI Article Synopsis
- The VDR rs2228570 polymorphism's impact on ovarian cancer risk has been investigated, but results remain uncertain
- A meta-analysis of 14 studies involving 10,964 participants was conducted to clarify this relationship
- The analysis found that the VDR rs2228570 polymorphism is significantly associated with an increased risk of ovarian cancer, especially among Caucasians, but further research is needed for other populations.
Article Abstract
The role of vitamin D receptor (VDR) rs2228570 polymorphism on the risk of ovarian cancer has been studied in many studies, but the relationship between VDR rs2228570 polymorphism and ovarian cancer is still unclear. We thus performed a meta-analysis of published studies to provide a comprehensive assessment of the association. Fourteen individual studies with a total of 10,964 subjects were finally included into the meta-analysis. We assessed the association by calculating the pooled odds ratio (OR) with 95 % confidence intervals (95 % CI). There was no heterogeneity among those included studies. Meta-analysis of 14 studies showed that the VDR rs2228570 polymorphism was associated with risk of ovarian cancer under three main comparison models (T versus C: OR = 1.09, 95 % CI 1.03 to 1.15, P = 0.004; TT versus CC: OR = 1.17, 95 % CI 1.04 to 1.32, P = 0.01; and TT/CT versus CC: OR = 1.12, 95 % CI 1.03 to 1.21, P = 0.007). Subgroup analysis in Caucasians further identified the obvious association. There was no evidence of publications bias. These data from the meta-analysis suggest that VDR rs2228570 polymorphism is associated with risk of ovarian cancer in Caucasians. More studies are warranted to assess the association between the VDR rs2228570 polymorphism and ovarian cancer in Asians and Africans.

Polymorphisms in the vitamin D receptor (VDR) gene (BsmI (rs1544410), FokI (rs2228570), ApaI (rs7975232), TaqI (rs731236)) and low vitamin D concentrations have previously been associated with type 1 diabetes (T1D). Vitamin D is thought to mediate the switch from a pro-inflammatory Th1 response to an anti-inflammatory Th2 response which is protective against the development of T1D. These associations are inconsistent across studies and population groups.

Background: The role of the vitamin D receptor single nucleotide polymorphism FOKI (VDR-FOKI) (rs2228570) in genetic susceptibility to type 2 diabetic kidney disease (T2DKD) remains uncertain. This study investigated the relationship between VDR-FOKI and T2DKD within the Chinese Plateau Han population and analyzed the underlying mechanisms.
Methods: A total of 316 subjects were enrolled, including 44 healthy adults, 114 individuals with type 2 diabetes mellitus (T2DM), and 158 patients with T2DKD.

Background: There is an ongoing controversy regarding the expression of vitamin D receptor (VDR) and binding protein (VDBP) genes, as well as their polymorphisms, in periodontitis. We examined eight single nucleotide polymorphisms (SNPs) and performed a transcriptome-level bioinformatics analysis to clarify their relationship with periodontitis.
Methods: To explore VDR and VDBP polymorphisms, 600 subjects were included, including 307 patients with chronic periodontitis (CP) and 293 healthy controls.

Objectives: The therapeutic potential of vitamin D has been studied regarding adjuvant interventions. Some studies have evaluated the factors associated with vitamin D deficiency (VDD) in healthy populations, but they are scarce in children and adolescents with type 1 diabetes mellitus (T1DM). The objective of this study was to describe the prevalence of and factors associated with VDD in children and adolescents with T1DM.

Aims: The association between vitamin D and the risk of venous thromboembolism (VTE) remains inconclusive. We aimed to explore the association of serum 25-hydroxyvitamin D (25OHD) with incident VTE among participants with and without diabetes, and examine the modifying effect of genetic susceptibility of VTE and vitamin D receptor (VDR) gene polymorphisms on this association.
Materials And Methods: A total of 378,082 participants free of VTE at baseline from the UK Biobank were included.
