Estrogen receptor α gene PvuII polymorphism and coronary artery disease: a meta-analysis of 21 studies.

ABSTRACT: The association between the estrogen receptor α gene (ESR1) PvuII polymorphism (c.454-397T>C) and coronary artery disease (CAD) is controversial. Thus, we conducted a meta-analysis to evaluate the relationship. Data were collected from 21 studies encompassing 9926 CAD patients and 16710 controls. Odds ratios (ORs) with 95% confidence intervals (CIs) were used to assess the relationship between PvuII polymorphism and CAD. The polymorphism in control populations in all studies followed Hardy-Weinberg equilibrium. We found a significant association between ESR1 PvuII polymorphism and CAD risk in all subjects. When the data were stratified by region, a significant association between ESR1 PvuII polymorphism and CAD risk was observed in Asian populations but not in Western populations. The current study suggests that ESR1 PvuII polymorphism has an important role in CAD susceptibility.

Association between Estrogen Receptor-α Gene XbaI and PvuII Polymorphisms and Periodontitis Susceptibility: A Meta-Analysis.

Project description:BackgroundCertain studies have previously explored the association between the estrogen receptor-α (ER-α) gene polymorphisms and periodontitis susceptibility, although the current results are controversial. The present study, using meta-analysis, aimed to investigate the nature of the genetic susceptibility of the ER-α for developing periodontitis.MethodsA comprehensive literature search of PubMed, Embase, CNKI, and Wanfang databases was conducted up to January 8, 2015. Statistical manipulation was performed using Stata version 13.0 software. Odds ratios (ORs) and corresponding 95% confident intervals (CIs) were calculated to estimate the association in five genetic models.ResultsA total of 17 eligible case-control studies from seven identified publications consisting of nine studies for the XbaI polymorphism and eight studies for the PvuII polymorphism were included in the meta-analysis. We found elevated risk of periodontitis in XbaI XX genotype carriers. Moreover, subgroup analyses demonstrated increased risk for chronic periodontitis of XbaI XX genotype carriers, specifically in the Chinese Han female population. No significant association was observed between PvuII polymorphism and periodontitis.ConclusionCurrent evidence indicated that the homozygote (XX) genotype of ER-α gene XbaI polymorphism, but not PvuII mutation, may increase the risk of chronic periodontitis, specifically in the Chinese Han female population.

Association between estrogen receptor-alpha gene PvuII and XbaI polymorphisms and osteoarthritis risk: a meta-analysis.

Project description:Estrogen receptor-alpha (ER-α) gene PvuII (T/C) and XbaI (A/G) polymorphisms have been hypothesized to be associated with osteoarthritis (OA) risk by several epidemiological studies, however, the available results were inconclusive and conflicting. We conducted a meta-analysis of 10 case-control studies that included 3328 osteoarthritis cases and 6390 case-free controls. We assessed the strength of the association, using odds ratios (ORs) with 95% confidence intervals (CIs). This meta-analysis showed that the ER-α PvuII and XbaI polymorphisms were not associated with OA risk in overall population. For the PvuII (T/C) polymorphism, however, in the subgroup analysis by country, a significantly reduced risk was observed among Chinese (TC vs. CC: OR = 0.73, 95% CI 0.54-0.99, I (2) = 0%, P heterogeneity = 0.498; dominant model, OR = 0.73, 95% CI = 0.55-0.98, I (2) = 0%, P heterogeneity = 0.555). For the XbaI (A/G) polymorphism, when stratifying by sample size, a significantly elevated risk was found in sample size ≤ 500 (AA vs. GG: OR = 2.60, 95% CI 1.10-6.18, I (2) = 42.9%, P heterogeneity = 0.135; dominant model: OR = 2.04, 95% CI 1.12-3.71, I (2) = 11.4%, P heterogeneity = 0.341; and recessive model: OR = 1.69, 95% CI 1.12-2.55, I (2) = 40.2%, P heterogeneity = 0.154). No publication bias was found in the present study. This meta-analysis suggests that ER-α PvuII (T/C) polymorphism may be associated with a reduced OA risk among Chinese and the XbaI (A/G) polymorphism may not be associated with OA risk, while the observed increase in OA risk for XbaI polymorphism may be due to small-study bias.

Association of estrogen receptor α PvuII and XbaI polymorphisms with prostate cancer susceptibility and risk stratification: a meta-analysis from case-control studies.

Project description:BackgroundStudies on the association between two single nucleotide polymorphisms (SNPs) in estrogen receptor α (ERα), PvuII (rs2234693 T>C) and XbaI (rs9340799 A>G), and the prostate cancer risk are inconsistent. Therefore, we performed a meta-analysis to derive a more accurate estimation of this relationship.MethodsA literature search of PubMed, Embase, Web of Science databases until October 1, 2016, was conducted. Crude odds ratios (ORs) with 95% confidence intervals (CIs) were calculated to assess the strength of this association.ResultsEighteen case-control studies, with a total of 3,317 prostate cancer patients and 8,324 controls, were included. Results showed that both PvuII and XbaI polymorphisms were significantly associated with a higher prostate cancer risk in overall populations. To derive a more accurate estimation, subgroup analysis stratified by ethnicity revealed that this relation-ship existed only in Caucasians, but not in Asians. Furthermore, PvuII polymorphism was significantly associated with high Gleason grade (Gleason score ≥7) cancers.ConclusionThe current meta-analysis demonstrates that ERα PvuII and XbaI polymorphisms are associated with a higher prostate cancer risk in Caucasians, but not in Asians, and PvuII polymorphism is significantly associated with high Gleason grade tumors, indicating the probability of inherited susceptibility to prostate cancer arising from different genomic ERα SNPs, which may help us understand the pathogenesis of prostate cancer in Caucasians.

Oestrogen receptor alpha PvuII polymorphism and uterine fibroid incidence in Caucasian women.

Project description:IntroductionUterine fibroids (UFs) are benign, monoclonal tumours of the female genital tract that originate from the myometrium. They may be diagnosed in as many as 80% of women depending on the selected population. UFs depend mostly on steroid hormones. Elevated levels of oestrogens and progesterone are believed to be among the most important factors inducing their formation and growth. These facts suggest that oestrogen (ESR) and progesterone receptors are crucial in UF pathophysiology as well. Previous studies have shown that, in some populations, polymorphisms in ESR genes (e.g. PvuII) constitute an important risk factor for UFs.Material and methodsThe aim of our study was to investigate whether ESRα PvuII polymorphism is associated with an increased risk of UFs in Caucasian women of Polish origin. A total of 197 patients (114 UF-positive and 83 controls) were included in this retrospective cohort study. ESRα gene polymorphism PvuII (rs2234693) was assayed with PCR and restriction fragment length polymorphism (RFLP).ResultsOur study found no significant difference in the occurrence of ESR PvuII polymorphism between women with UFs and UF-free controls in the selected population.ConclusionsOur results did not indicate a significant association between ESRα gene PvuII polymorphism and the risk of UFs in Caucasian women of Polish origin. More studies and comparisons between races are necessary to clarify the role of ESRα in the development and progression of UFs.

Risk of premature ovarian failure is associated to the PvuII polymorphism at estrogen receptor gene ESR1.

Project description:PurposeEstrogen plays an important role in the human reproductive system and it action is mediated mainly by two specific receptors: α (ERα) and β (ERβ). There were described polymorphic variants in ESR1 and ESR2 genes and studies showed controversial results regarding their association with premature ovarian failure. We aimed to determine the prevalence of ESR1 and ESR2 polymorphisms in Brazilian patients and controls. After associate the polymorphisms with premature ovarian failure (POF).MethodsGenetic association study was performed with 70 women with POF and 73 normally menopaused controls. Detection of ESR1 (PvuII/and XbaI) and ESR2 (AluI and RsaI) gene polymorphisms were performed using TaqMan PCR. The single-nucleotide polymorphism (SNPs) and haplotype effects were analyzed by multivariate logistic regression and haplotype analysis and a p-value < 0.05 was considered significant.ResultsIndividual SNP analysis revealed that PvuII polymorphism was statistically associated with POF (p = 0.034) under a recessive model. Regarding XbaI, AluI and RsaI SNPs, no statistical difference was observed between POF group and controls (p = 0.575, p = 0.258 and p = 0.483, respectively). Combined genotypes of ESR1 and ESR2 polymorphisms did not identify a risk haplotype associated with POF.ConclusionIn Brazilian population evaluated results have demonstrated that the genetic variation in ESR1 gene (PvuII polymorphism) is associated to POF risk.

Association between estrogen receptor α gene (ESR1) PvuII (C/T) and XbaI (A/G) polymorphisms and hip fracture risk: evidence from a meta-analysis.

Project description:Background and objectiveGenetic factors are important in the pathogenesis of fractures. Notably, estrogen receptor α (ESR1) has been suggested as a possible candidate gene for hip fractures; however, published studies of ESR1 gene polymorphisms have been hampered by small sample sizes and inconclusive or ambiguous results. The aim of this meta-analysis is to investigate the associations between two novel common ESR1 polymorphisms (intron 1 polymorphisms PvuII-rs2234693: C>T and XbaI-rs9340799: A>G) and hip fracture.MethodsCrude odds ratios (ORs) with 95% confidence intervals (CIs) were used to evaluate the strength of the association.ResultsFive case-control and three cohort studies were assessed, including a total of 1,838 hip fracture cases and 14,972 healthy controls. This meta-analysis revealed that the PvuII T allele is a highly significant risk factor for hip fracture susceptibility, with an effect magnitude similar in male and pre-menopausal and post-menopausal female patients. In stratified analysis based on ethnicity, the PvuII T allele remained significantly correlated with increased risk of hip fracture in Caucasian populations; this correlation, however, was not found in Asian populations. Unlike the PvuII polymorphism, we did not find significant differences in the XbaI (A>G) polymorphism allele or genotype distributions of hip fracture patients and controls. We also found no obvious association between the XbaI polymorphism and hip fracture in any of the racial or gender subgroups.ConclusionOur findings show that the ESR1 PvuII T allele may increase the risk of hip fracture and that the XbaI polymorphism is not associated with hip fracture.

The association between estrogen receptor 2 gene polymorphism and complexity of coronary artery disease: an analysis in elective percutaneous coronary intervention patients.

Project description:BackgroundOne of the most common causes of death in the world is coronary artery disease (CAD). Estrogen, the most important early sex hormones in women, plays an important role in the risk reduction of cardiovascular disease (CVD). Expression of estrogen as well as its receptors including estrogen receptor alpha (ER1) and estrogen receptor beta (ER2) might have an association with the severity or the complexity of CAD. Since most articles have focused on the relationship between ER1 gene polymorphism and CAD, in this study, we aimed to evaluate the association of two ER2 gene polymorphisms, rs4986938 (AluI) and rs1256049 (RsaI), with the severity of CAD.Methods148 patients with confirmed CAD who underwent elective percutaneous coronary intervention (PCI) were included in this study. Blood samples were collected before coronary angiography and ER2 gene polymorphisms were analyzed by the PCR-RFLP method. The STNTAX Score (SS), grading system for CAD complexity, was evaluated by an interventional cardiologist who was blinded to other data.Results110 men and 38 women were participated in this study. Our results revealed a statistically significant relationship between SS and rs4986938 polymorphism of ER2 in men. In contrast, there was no association between rs1256049 genotypes and SS after performing regression analysis.ConclusionsBesides to the estrogen level, the genetic variation of its receptors might play an important role in the severity or the complexity of CAD. According to our results, rs4986938 polymorphism of ER2 gene may assert a pivotal role in the severity of CAD in men; however, this assumption needs to be proved in studies with a larger population.

Associations of serum estradiol level, serum estrogen receptor-alpha level, and estrogen receptor-alpha polymorphism with male infertility: A retrospective study.

Project description:AbstractEstradiol regulates spermatogenesis partly via estrogen receptor-alpha (ESRα). This study aimed to analyze the associations of serum estradiol level, serum ESRα level, and ESRα gene polymorphisms with sperm quality.This retrospective study included infertile men attending the Reproductive Center, Affiliated Hospital of Youjiang Medical University for Nationalities, and a control group without a history of fertility (October, 2016 to March, 2017). Data regarding sperm quality, serum levels of estradiol and ESRα, and rs2234693C/T genotype were extracted from the medical records. Pearson/Spearman correlations (as appropriate) between estradiol level, ESRα level, and sperm quality parameters were evaluated.The analysis included 215 men with infertility and 83 healthy controls. The infertile group had higher serum levels of estradiol (147.57 ± 35.3 vs 129.62 ± 49.11 pg/mL, P < .05) and ESRα (3.02 ± 2.62 vs 1.33 ± 0.56 pg/mL, P < .05) than the control group. For the infertile group, serum estradiol level was negatively correlated with sperm concentration, percentage of progressively motile sperm, and percentage of sperm with normal morphology (r = 0.309, 0.211, and 0.246, respectively; all P < .05). Serum estradiol and ESRα levels were lower in infertile men with normozoospermia than in those with azoospermia, oligozoospermia, mild azoospermia, or malformed spermatozoa (all P < .05). Sperm concentration, percentage of progressively motile sperm, serum ESRα level, and serum estradiol level did not differ significantly among the rs2234693 CC, CT, and TT genotypes.Elevated serum levels of estradiol and possibly ESRα might have a negative impact on sperm quality and fertility, whereas single nucleotide polymorphisms at rs2234693 of the ESRα gene had little or no effect.

Estrogen receptor α polymorphism in a species with alternative behavioral phenotypes.

Project description:The evolution of behavior relies on changes at the level of the genome; yet the ability to attribute a behavioral change to a specific, naturally occurring genetic change is rare in vertebrates. In the white-throated sparrow (Zonotrichia albicollis), a chromosomal polymorphism (ZAL2/2(m)) is known to segregate with a behavioral phenotype. Individuals with the ZAL2(m) haplotype engage in more territorial aggression and less parental behavior than individuals without it. These behaviors are thought to be mediated by sensitivity to sex steroids, and the chromosomal rearrangement underlying the polymorphism has captured a prime candidate gene: estrogen receptor 1 (ESR1), which encodes estrogen receptor α (ERα). We therefore hypothesized that the behavioral effects of the ZAL2(m) rearrangement are mediated by polymorphism in ESR1. We report here that (i) the ESR1 promoter region contains fixed polymorphisms distinguishing the ZAL2(m) and ZAL2 alleles; (ii); those polymorphisms regulate transcription efficiency in vitro and therefore potentially do the same in vivo (iii); the local expression of ERα in the brain depends strongly on genotype in a free-living population; and (iv) ERα expression in the medial amygdala and medial preoptic area may fully mediate the effects of genotype on territorial aggression and parenting, respectively. Thus, our study provides a rare glimpse of how a chromosomal polymorphism has affected the brain and social behavior in a vertebrate. Our results suggest that in this species, differentiation of ESR1 has played a causal role in the evolution of phenotypes with alternative life-history strategies.
