Haplotype of ESR1 and PPARD Genes Is Associated with Higher Anthropometric Changes in Han Chinese Obesity by Adjusting Dietary Factors-An 18-Month Follow-Up. Nutrients 2022; 14:nu14204425. [PMID: 36297109 PMCID: PMC9611750 DOI: 10.3390/nu14204425] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/03/2022] [Revised: 10/11/2022] [Accepted: 10/12/2022] [Indexed: 11/05/2022] Open
Abstract
The obesity genetic effect may play a major role in obesogenic environment. A combined case-control and an 18-month follow-up were carried out, including a total of 311 controls and 118 obese cases. All participants were aged in the range of 20-55 y/o. The body mass index (BMI) of obese cases and normal controls was in the range of 27.0-34.9 and 18.5-23.9 kg/m2, respectively. The rs712221 on Estrogen receptor1 (ESR1) and rs2016520 on Peroxisome proliferator-activated receptor delta (PPARD) showed significant associations with obesity. The TT (odds ratio (OR): 2.42; 95% confidence interval (CI): 1.46-4.01) and TT/TC (OR: 2.80; 95% CI: 1.14-6.85) genotypes on rs712221 and rs2016520 had significantly higher obesity risks, respectively. Moreover, the synergic effect of these two risk SNPs (2-RGH) exhibited an almost geometrical increase in obesity risk (OR: 7.00; 95% CI: 2.23-21.99). Obese individuals with 2-RGH had apparently higher changes in BMI increase, body weight gain and dietary fiber intake but a lower total energy intake within the 18-month follow-up.

Glucose-Related Traits and Risk of Migraine—A Potential Mechanism and Treatment Consideration. Genes (Basel) 2022; 13:genes13050730. [PMID: 35627115 PMCID: PMC9141901 DOI: 10.3390/genes13050730] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/22/2022] [Revised: 04/19/2022] [Accepted: 04/19/2022] [Indexed: 12/16/2022] Open
Abstract
Migraine and glucose-related (glycaemic) traits (fasting glucose, fasting insulin, and type 2 diabetes) are common and complex comorbid disorders that cause major economic and social burdens on patients and their families. Studies on the relationship between migraine and glucose-related traits have yielded inconsistent results. The purpose of this review is to synthesise and discuss the information from the available literature on the relationship between fasting glucose, fasting insulin, and type 2 diabetes (T2D) with migraine. Publications on migraine and fasting glucose, migraine and fasting insulin, and migraine and T2D were identified from a PubMed and Google Scholar database search and reviewed for this article. Multiple publications have suggested that the comorbidity of migraine and glucose-related traits may have a similar complex pathogenic mechanism, including impaired glucose homeostasis, insulin resistance, reduced cerebrovascular reactivity, abnormal brain metabolism, shared genetic factors, neurotransmitters, and sex hormones. Furthermore, several studies have found a bi-directional link between migraine with insulin resistance and T2D. There is strong evidence for a biological association between migraine headache and glucose-related traits, and burgeoning evidence for shared genetic influences. Therefore, genetic research into these comorbid traits has the potential to identify new biomarkers and therapeutic targets and provide biological insight into their relationships. We encourage healthcare professionals to consider the co-occurrence of migraine with glucose-related traits in the evaluation and treatment of their patients.

Linear and nonlinear analyses of the association between low-density lipoprotein cholesterol and diabetes: The spurious U-curve in observational study. Front Endocrinol (Lausanne) 2022; 13:1009095. [PMID: 36465637 PMCID: PMC9714469 DOI: 10.3389/fendo.2022.1009095] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/01/2022] [Accepted: 11/02/2022] [Indexed: 11/18/2022] Open
Abstract
OBJECTIVE Hyperlipidemia is traditionally considered a risk factor for diabetes. The effect of low-density lipoprotein cholesterol (LDL-C) is counterintuitive to diabetes. We sought to investigate the relationship between LDL-C and diabetes for better lipid management. METHODS We tested the shape of association between LDL-C and diabetes and created polygenic risk scores of LDL-C and generated linear Mendelian randomization (MR) estimates for the effect of LDL-C and diabetes. We evaluated for nonlinearity in the observational and genetic relationship between LDL-C and diabetes. RESULTS Traditional observational analysis suggested a complex non-linear association between LDL-C and diabetes while nonlinear MR analyses found no evidence for a non-linear association. Under the assumption of linear association, we found a consistently protective effect of LDL-C against diabetes among the females without lipid-lowering drugs use. The ORs were 0.84 (95% CI, 0.72-0.97, P=0.0168) in an observational analysis which was more prominent in MR analysis and suggested increasing the overall distribution of LDL-C in females led to an overall decrease in the risk of diabetes (P=0.0258). CONCLUSIONS We verified the liner protective effect of LDL-C against diabetes among the females without lipid-lowering drug use. Non-linear associations between LDL-C against diabetes in observational analysis are not causal.

Use of Network Pharmacology to Explore the Mechanism of Gegen ( Puerariae lobatae Radix) in the Treatment of Type 2 Diabetes Mellitus Associated with Hyperlipidemia. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2021; 2021:6633402. [PMID: 33953784 PMCID: PMC8068526 DOI: 10.1155/2021/6633402] [Citation(s) in RCA: 17] [Impact Index Per Article: 5.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 11/05/2020] [Revised: 03/05/2021] [Accepted: 04/06/2021] [Indexed: 01/04/2023]
Abstract
Rapid increases in metabolic disorders, such as type 2 diabetes mellitus (T2DM) and hyperlipidemia, are becoming a substantial challenge to worldwide public health. Traditional Chinese medicine has a long history and abundant experience in the treatment of diabetes and hyperlipidemia, and Puerariae lobatae Radix (known as Gegen in Chinese) is one of the most prevalent Chinese herbs applied to treat these diseases. The underlying mechanism by which Gegen simultaneously treats diabetes and hyperlipidemia, however, has not been clearly elucidated to date. Therefore, we systematically explored the potential mechanism of Gegen in the treatment of T2DM complicated with hyperlipidemia based on network pharmacology. We screened the potential targets of Gegen, T2DM, and hyperlipidemia in several online databases. Then, the hub targets were analyzed by performing protein-protein interaction, Gene Ontology (GO), and Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment assays, and finally, the complicated connections among compounds, targets, and pathways were visualized in Cytoscape. We found that isoflavones, including daidzein, genistein, and puerarin, as well as β-sitosterol, are the key active ingredients of Gegen responsible for its antidiabetic and antihyperlipidemia effects, which mainly target AKR1B1, EGFR, ESR, TNF, NOS3, MAPK3, PPAR, CYP19A1, INS, IL6, and SORD and multiple pathways, such as the PI3K-Akt signaling pathway; the AGE-RAGE signaling pathway in diabetic complications, fluid shear stress, and atherosclerosis; the PPAR signaling pathway; insulin resistance; the HIF-1 signaling pathway; the TNF signaling pathway; and others. These active ingredients also target multiple biological processes, including the regulation of glucose and lipid metabolism, the maintenance of metabolic homeostasis, and anti-inflammatory and antioxidant pathways. In conclusion, Gegen is a promising therapeutic phytomedicine for T2DM with hyperlipidemia that targets multiple proteins, biological processes, and pathways.

[PMID: 33360539 DOI: 10.1016/j.eplepsyres.2020.106527] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/30/2019] [Revised: 11/24/2020] [Accepted: 12/05/2020] [Indexed: 11/27/2022]
Abstract
OBJECTIVE Women with epilepsy (WWE) have a high risk of sexual dysfunction (SD). We aimed to investigate the incidence of SD, the correlation between SD, sex hormone and estrogen receptor (ER) gene polymorphism in Chinese Han WWE. METHODS This cross-sectional study examined 112 married WWE in the Affiliated Hospital of Yangzhou University who were taking antiepileptic drugs (AEDs) for ≥1 year, and 120 healthy controls without epilepsy, all of Chinese Han nationality. The age, menstruation, fertility of all the subjects and disease details of WWE were recorded. The Chinese version of female sexual function index (FSFI) was used to investigate the sexual function of the subjects. The chemiluminescence method was used for the detection of sex hormones, while polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) was used to determine the ER gene polymorphism. The differences of the sexual function, sex hormone, ER genotype, and allele frequency were compared between the two groups. The correlation between SD, sex hormone and ER gene polymorphism was also analyzed. RESULTS (1) A high rate (70.5%) of SD was detected in WWE. (2) The serum prolactin (PRL) level (P = 0.039) and the ratio of estradiol to progesterone (E2/P) (P<0.001) in the WWE group were significantly higher than those in the control group. The allele frequencies of ERα-PvuII C (P = 0.001) and ERβ-AluI A (P = 0.001) in the WWE group were significantly higher than those in the control group. (3) Binary logistic regression analysis showed that serum testosterone level [odds ratio (OR) = 0.412, 95 % confidence interval (CI): 0.201-0.842, P = 0.015], and PvuII CC genotype [odds ratio (OR) = 6.074, 95 % confidence interval (CI): 1.257-29.352, P = 0.025] were independently correlated with SD. CONCLUSION The incidence of SD in Chinese Han WWE is high. High serum testosterone levels may exert a protective effect on sexual function. ERα-PvuII polymorphism is related to the susceptibility of SD, and PvuII CC genotype may be the risk genotype of SD.

Abstract
BACKGROUND The estrogen receptor-1 (ESR1) gene encodes estrogen receptor-α, which is a major biomarker in the development of breast cancer. This study aimed to investigate the effect of ESR1 polymorphisms on breast cancer in Chinese Han women. MATERIALS AND METHODS We genotyped 4 candidate single nucleotide polymorphisms (SNPs) in ESR1 among 503 patients with breast cancer and 503 healthy people using the Agena MassARRAY platform. The association between ESR1 polymorphisms and breast cancer risk was evaluated using odds ratios (ORs) and 95% confidence intervals (95% CIs) under 4 genetic models. The HaploReg v4.1 and GEPIA database were used for SNP functional annotation and ESR1 expression analysis, respectively. RESULTS The T allele of rs9383938 in ESR1 was significantly associated with an increased breast cancer risk (OR, 1.26; 95% CI, 1.05-1.50; P = .013). In genetic models, rs9383938 increased breast cancer risk in the codominant model (OR, 1.54; 95% CI, 1.07-2.22; P = .021), the dominant model (OR, 1.31; 95% CI, 1.01-1.68; P = .040), and the additive model (OR, 1.24; 95% CI, 1.04-1.48; P = .017). Stratification analysis showed that rs9383938 and rs2228480 raised the breast cancer susceptibility in individuals aged younger than 52 years old. Rs1801132 of ESR1 was significantly associated with the status of estrogen receptor, progesterone receptor, and human epidermal growth factor receptor 2 in the allele model and genetic models (P < .05). CONCLUSIONS This study demonstrated that ESR1 polymorphisms might influence breast cancer susceptibility in the Chinese Han population. Further mechanism studies are needed to confirm the contribution of ESR1.

[PMID: 32682401 PMCID: PMC7368753 DOI: 10.1186/s12872-020-01618-7] [Citation(s) in RCA: 11] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/05/2020] [Accepted: 07/09/2020] [Indexed: 12/29/2022] Open
Abstract
Background Coronary artery disease (CAD) is a complex disease resulting from the cumulative and interactive effects of large number of genes along with environmental exposure. Therefore, the present study was envisaged as an effort to study the association of candidate genes ESR1 (rs2234693 and rs9340799), CETP (rs708272), MTHFR (rs1801133 and rs2274976) and MS (rs185087) polymorphisms with the risk of CAD, targeting the populations of Jammu (JandK). Method A total of 400 confirmed CAD patients and 400 healthy controls were enrolled for the present study. Genotyping was done by polymerase chain reaction- restriction fragment length polymorphism (PCR-RFLP). Results ESR1 gene (rs9340799) polymorphism was found to be associated with CAD in all the genetic models. The haplotype analysis of ESR1 (rs2234693 and rs9340799) gene revealed that C-G haplotype was conferring approximately 5-fold risk and T-A haplotype was adding 1.4-fold risk towards the disease. ‘T’ allele of MTHFR rs1801133 SNP was observed to be responsible for development of CAD in our study population (p < 0.0001). In case of MTHFR (rs1801133 and rs2274976) gene, the haplotype T-G was observed to confer 4.7-fold risk towards CAD whereas haplotype C-G provided nearly a 1.7 fold protection towards development of CAD. For MS gene, rs185087 was also found to be associated with CAD in a co-dominant (p = 0.003 and p = 0.03), dominant (p = 0.001) and allelic models (p = 0.001). The gene-gene interaction revealed strong epistasis between single nucleotide polymorphisms (SNPs), ESR1 rs9340799 and MTHFR rs2274976. Furthermore, the dendrogram for gene-environment dataset indicated moderately synergistic interaction between CETP rs708272 and physical inactivity. Conclusion In the study under reference, a significant association of ESR1-XbaI (rs9340799), MTHFR C677T (rs1801133) and MS A2756G (rs185087) gene polymorphisms with the susceptibility of CAD in the population of Jammu region (JandK) has been observed.

[PMID: 31293826 PMCID: PMC6601601 DOI: 10.7717/peerj.7164] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/13/2019] [Accepted: 05/21/2019] [Indexed: 12/24/2022] Open
Abstract
Background Type 2 diabetes mellitus (T2DM) is a multifactorial disease where both genetic and environmental factors contribute to its pathogenesis. The PvuII and XbaI polymorphisms of the estrogen receptor 1 (ESR1) gene have been variably associated with T2DM in several populations. This association has not been studied in the Palestinian population. Therefore, the aim of this study was to investigate the association between the PvuII and XbaI variants in the ESR1 and T2DM and its related metabolic traits among Palestinian women. Methods This case-control study included 102 T2DM and 112 controls in which PvuII and XbaI variants of the ESR1 gene were genotyped using amplicon based next generation sequencing (NGS). Results Allele frequencies of both PvuII and XbaI variants were not significantly different between patients and control subjects (P > 0.05). In logestic regression analysis adjusted for age and BMI, the ESR1 PvuII variant was associated with risk of T2DM in three genotypic models (P < 0.025) but the strongest association was observed under over-dominant model (TT+CC vs. TC) (OR = 2.32, CI [1.18-4.55] adjusted P = 0.013). A similar but non-significant trend was also observed for the ESR1 XbaI variant under the over-dominant model (AA+GG vs. AG) (OR = 2.03, CI [1.05-3.95]; adjusted P = 0.035). The frequencies of the four haplotypes (TA, CG, CA, TG) were not significantly different in the T2DM patients compared with control group (P > 0.025). Among diabetic group, an inverse trend with risk of cardio vascular diseases was shown in carriers of CG haplotype compared to those with TA haplotype (OR = 0.28, CI [0.09-0.90]; adjusted P = 0.035). Further, stratified analyses based on ESR1 PvuII and XbaI genotypes revealed no evidence for association with lipid levels (TC, TG, HDL, LDL). Conclusions This is the first Palestinian study to conclude that ESR1 PuvII and XbaI variants may contribute to diabetes susceptibility in Palestinian women. Identification of genetic risk markers can be used in defining high risk subjects and in prevention trials.

GENES AND NUTRITION 2019; 14:16.

Abstract
Background Variability in circulating carotenoids may be attributable to several factors including, among others, genetic variants and lipid profile. However, relatively few studies have considered the impact of gene expression in the inter-individual variability in circulating carotenoids. Most studies considered expression of genes individually and ignored their high degree of interconnection. Weighted gene co-expression network analysis (WGCNA) is a systems biology method used for finding gene clusters with highly correlated expression levels and for relating them to phenotypic traits. The objective of the present observational study is to examine the relationship between plasma total carotenoid concentrations and lipid profile using WGCNA. Results Whole blood expression levels of 533 probes were associated with plasma total carotenoids. Among the four WGCNA distinct modules identified, turquoise, blue, and brown modules correlated with plasma high-density lipoprotein cholesterol (HDL-C) and total cholesterol. Probes showing a strong association with HDL-C and total cholesterol were also the most important elements of the brown and blue modules. A total of four and 29 hub genes associated with total carotenoids were potentially related to HDL-C and total cholesterol, respectively. Conclusions Expression levels of 533 probes were associated with plasma total carotenoid concentrations. Using WGCNA, four modules and several hub genes related to lipid and carotenoid metabolism were identified. This integrative analysis provides evidence for the potential role of gene co-expression in the relationship between carotenoids and lipid concentrations. Further studies and validation of the hub genes are needed.

Abstract
Both post-traumatic stress disorder (PTSD) and estrogen receptor alpha (ESR1) gene rs2234693 were reported to influence serum glucose and lipids profiles. However, their interactions on serum glucose and lipids profiles have not been reported. A total of 708 Chinese Han high school students were recruited at 6th months after the 2008 Wenchuan Earthquake. Serum concentrations of fasting blood glucose (FBG), fasting blood insulin (FBI), total cholesterol (TC), triglyceride (TG), low-density lipoprotein cholesterol (LDL-C) and high-density lipoprotein cholesterol (HDL-C) were detected. Body mass index (BMI) and homeostatic model assessment of insulin resistance (HOMA-IR) were calculated. PTSD was assessed by the PTSD Checklist Civilian Version (PCL-C). Variants of ESR1 rs2234693 was analyzed by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) analyses and verified by DNA sequencing. The male subjects with PTSD had a trend of higher FBG (p = 0.077) and significantly higher FBI and HOMA-IR than male controls. The PTSD subjects had significantly higher levels of FBG, FBI, HOMA-IR and HDL-C than the controls only in the male C allele carriers irrespective of adjustment for age and BMI. In the male controls group, the C allele carriers had significantly lower HDL-C than the TT homozygotes regardless of adjustment for age and BMI. In female PTSD group, the C allele carriers had significantly higher TC/HDL-C and LDL-C/HDL-C than the TT homozygotes after adjustment for age and BMI. These results suggest the interplays of ESR1 rs2234693 with PTSD influence serum glucose and lipids profiles with a gender dependent manner.

BMC Endocr Disord 2018; 18:65. [PMID: 30217154 PMCID: PMC6137943 DOI: 10.1186/s12902-018-0289-4] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/14/2018] [Accepted: 08/24/2018] [Indexed: 01/21/2023] Open
Abstract
BACKGROUND Metabolic syndrome (MetS) includes obesity, diabetes, dyslipidemia and hypertension. Its incidence is rapidly increasing worldwide, particularly in postmenopausal women. Estrogens regulate glucose homeostasis and lipid metabolism via estrogen receptors 1 (ESR1) and 2 (ESR2). The current study aimed to elucidate associations of MetS with ESR1 and ESR2 gene polymorphisms in postmenopausal Chinese women. METHODS This case-control study included 304 postmenopausal women (154 and 150 control and MetS patients, respectively). Clinical indicators related to MetS were assessed. Two ESR1 (PvuII and XbaI) and two ESR2 (RsaI and AluI) polymorphisms were evaluated by polymerase chain reaction (PCR)-restriction fragment length polymorphism analysis. RESULTS ESR1 polymorphisms were significantly different between MetS patients and healthy controls. G allele frequency for the XbaI polymorphism was significantly higher in patients than in control patients (p = 0.004, OR = 1.610, 95%CI 1.169-2.18). The haplotypes A-T (p = 0.015) and G-C (p = 0.024) showed significant differences. The minor alleles of the XbaI and PvuII gene polymorphisms in both homozygous and heterozygous forms showed associations with elevated waist circumference, fasting serum insulin and HOMA-IR. The minor G allele in homozygous and heterozygous forms of the RsaI and AluI gene polymorphisms showed associations with elevated total cholesterol and LDL-C. CONCLUSIONS In postmenopausal Chinese women, ESR1 polymorphism and the haplotypes A-T and G-C of XbaI-PvuII are associated with MetS, unlike ESR2 polymorphisms. Patients harboring the G allele of XbaI have elevated BMI, waist circumference, systolic and diastolic BP, FBG, HOMA-IR, total cholesterol, TG, LDL-C and NAFLD (%), and reduced HDL-C.

Associations of ESR1 and ESR2 gene polymorphisms with metabolic syndrome and its components in postmenopausal women. Maturitas 2018; 115:97-102. [PMID: 30049354 DOI: 10.1016/j.maturitas.2018.06.017] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/27/2018] [Revised: 06/15/2018] [Accepted: 06/30/2018] [Indexed: 12/15/2022]
Abstract
OBJECTIVES Metabolic syndrome (MS) affects a quarter of Polish people and is associated with diabetes mellitus type 2 and ischemic heart disease. The prevalence of MS in postmenopausal women can be increased by the lack of protective effects of oestrogens. In the near future, because of the general increase in life expectancy, the number of postmenopausal women will rise substantially. Therefore, investigating both the environmental and the genetic factors predisposing to MS may have a great impact on women's health. The aim of this study was to determine whether particular oestrogen receptor (ESR) gene polymorphisms can predispose to the development of MS in women after menopause. STUDY DESIGN The sample consisted of 147 postmenopausal women. In addition to collecting medical history and analyzing body composition using the TANITA scale, patient's waist size, blood pressure, serum lipids, glucose, insulin, C-reactive protein and adiponectin were measured. The analysis of ESR gene polymorphisms was performed using the Sequenom MassARRAY platform. RESULTS Three out of ten analyzed polymorphisms in the ESR1 gene (rs2234693, rs6902771, rs7774230) and one out of eight analyzed polymorphisms in the ESR2 gene (rs3020449) were associated with MS. The ESR1 rs2234693, rs6902771 and rs7774230 polymorphisms were associated with serum concentrations of high-density lipoproteins. The ESR2 rs3020449 polymorphism was associated with serum concentrations of total cholesterol and low-density lipoprotein. Four ESR1 polymorphisms (rs1709183, rs2234693, rs6902771, rs7774230) were associated with total fat tissue content. CONCLUSIONS Bearing the particular alleles at the ESR gene polymorphisms may impact the development of MS and some of the ESR polymorphisms may influence serum cholesterol concentrations in women after menopause.

Abstract
AIMS We aimed to analyze genetic polymorphism of estrogen receptor (ESR) 1 and ESR2 in a series of postmenopausal women with Takotsubo syndrome (TS). METHODS In total, 81 consecutive white women were prospectively enrolled: 22 with TS (TS group; mean age 71.2 ± 9.8 years), 22 with acute myocardial infarction (MI group; mean age 73.2 ± 8 years), and 37 asymptomatic healthy controls (CTRL group; mean age 69 ± 4.2 years). Genotyping of ESR1 -397C>T (rs2234693) and -351A>G (rs9340799) and ESR2 -1839G>T (rs 1271572) and 1082G>A (rs1256049) genetic variants was performed. We estimated the odds ratio (OR) between the genotype of each examined locus with the occurrence of TS or MI. RESULTS The risk of experiencing TS was higher for those study participants carrying the T allele at the rs2234693 locus of the ESR1 gene [OR: 2.0, 95% confidence interval (CI): 0.973-4.11, P = 0.04, TS vs. MI + CTRL; OR: 2.79, 95% CI: 1.17-6.64, P = 0.016, TS vs. MI alone]. Women carrying a T allele at the rs1271572 locus of the ESR2 gene demonstrated an even higher risk (OR: 3.23, 95% CI: 1.55-6.73, P = 0.0019, TS vs. MI + CTRL; OR: 9.13, 95% CI: 2.78-29.9, P = 0.0001, TS vs. MI alone). CONCLUSION The study reports preliminary findings suggesting a possible link between ESR polymorphisms and the occurrence of TS. Larger studies are needed to confirm our results.

Abstract
Estrogen might play an important role in type 2 diabetes mellitus pathogenesis. A number of polymorphisms have been reported in the estrogen receptor alpha gene including the XbaI and PvuII restriction enzyme polymorphisms. The aim of this study was to determine if ESRα gene polymorphisms are associated with type 2 diabetes mellitus and correlated with lipid profile. Ninety diabetic Egyptian patients were compared with forty healthy controls. ESRα genotyping of PvuII and XbaI was performed using restriction fragment length polymorphism analysis. Our study showed that there is more significant difference in the frequency of C and G polymorphic allele between patients and control groups in PvuII and XbaI respectively. Also carriers of minor C and G alleles of PvuII and XbaI gene polymorphisms were associated with increased fasting blood glucose and disturbance in lipid profile as there is an increase in total cholesterol, triglycerides and Low density lipoprotein. So findings of present study suggest the possibility that PvuII and XbaI polymorphisms in ERα are related to T2DM and with increased serum lipids among Egyptian population.

Abstract
OBJECTIVE The association of four single nucleotide polymorphisms in estrogen receptor alpha (ESR1) and beta (ESR2) genes with lipid levels and insulin resistance in men. DESIGN AND METHODS Lipids, glucose, insulin and HOMA-IR were determined, in a population-based, cross-sectional, cohort of 170 apparently healthy middle-aged Greek men, along with body mass index (BMI), waist circumference (WC) and percentage of body fat content (%fat). Genotyping of ESR1 for PvuII and XbaI and ESR2 for RsaI and AluI polymorphisms was performed. RESULTS Associations of AluI with LDL-Chol (mean ± SD, aa 4.3 ± 1.1 vs. Aa 3.7 ± 1.0 and ΑΑ 4.2 ± 1.1, p = 0.023) and RsaI with HOMA-IR [median (IQR), RR 1.55 (0.88-2.49) vs. Rr/rr 1.69 (0.72-2.29), p = 0.032] were found. Synergistic effects of RsaI and AluI of ESR2 gene on LDL-Chol levels, %fat and WC, as well as a synergistic effect of both ESR1 and ESR2 genes on levels of TChol (p = 0.01) and LDL-Chol (p = 0.027) were also shown. These findings remained significant after adjustment for potential confounders. Significant independent associations of PvuII with %fat (mean ± SD, pp 24.6 ± 5.3 vs Pp 22.4 ± 5.2 and PP 21.2 ± 6.7, p = 0.044), and RsaI with %fat (RR 22.6 ± 5.5 vs. Rr/rr 25.2 ± 6.3, p = 0.015) and WC (mean ± SD, RR 97.4 ± 10.4 vs. Rr/rr 102.6 ± 12.6, p = 0.013) were found. Synergistic effects on %fat, between the ESR1 polymorphisms (p = 0.004), between the ESR2 polymorphisms and among all four ESR polymorphisms studied were also present. CONCLUSIONS ESR2 is associated with LDL-Chol levels and HOMA-IR in men independently of confounders. Body fat is affected by both genes. Furthermore, a synergistic effect of ESR1 and ESR2 on TChol, LDL-Chol and %fat, was shown.

Estrogen receptor αlpha gene (ESR1) PvuII and XbaI polymorphisms are associated to metabolic and proinflammatory factors in polycystic ovary syndrome. Gene 2015; 560:44-9.

Abstract
BACKGROUND Polycystic ovary syndrome (PCOS) is a complex endocrine disorder that involves multiple factors. Although the etiology of PCOS is unknown, there is an involvement of sex steroid hormones in the pathophysiology of this syndrome. Therefore, polymorphisms in genes involved in the action of estrogen may contribute to a woman's susceptibility to PCOS. AIM This study aimed to evaluate the association between the polymorphisms PvuII and XbaI in the estrogen receptor alpha (ESR1) gene and the occurrence of PCOS. The study also aimed to assess the influence of these polymorphisms on the metabolic and inflammatory profiles of women with PCOS. MATERIAL AND METHODS This case-control study included 99 women with PCOS, diagnosed according to the Rotterdam criteria, and 104 age-matched healthy women. The polymorphisms were evaluated using polymerase chain reaction-restriction fragment length polymorphism. RESULTS No association between the ESR1 gene polymorphisms and the presence of PCOS was observed. However, we found associations between the PvuII polymorphism and C-reactive protein levels, testosterone levels, family history of diabetes, and waist circumference. The XbaI polymorphism was associated with fasting glucose and a family history of hypertension. CONCLUSION These polymorphisms are not associated with PCOS development, but they are involved in the phenotype of complications of the syndrome. Therefore, prior knowledge of these genomic variants might contribute to taking preventive measures that could delay the metabolic and reproductive complications commonly seen in women with PCOS.

Abstract
BACKGROUND Fasting plasma glucose (FPG) levels are usually tightly regulated within a narrow physiologic range. Variation of FPG levels is clinically important and is strongly heritable. Several lines of evidence suggest the importance of the oestrogen receptor α (ER-α) and osteocalcin (also known as BGP, for bone Gla protein) in determining FPG; however, whether their polymorphisms are associated with FPG variation is not well understood. AIM To investigate whether ER-a PvuII and BGP HindIII genetic polymorphisms and their potential interaction are associated with FPG variation. SUBJECTS AND METHODS The study subjects were 328 unrelated pre-menopausal Chinese women aged 21 years and over (mean age ± SD, 33.2 ± 5.9 years), with an average FPG of 4.92 (SD = 0.81). All subjects were genotyped at the ER-α PvuII and BGP HindIII loci using polymerase chain reaction (PCR)-restriction fragment length polymorphism (RFLP). RESULTS The ER-α PvuII genotypes were significantly associated with FPG (p = 0.007). In addition, a significant interaction was observed of the ER-α PvuII polymorphism with BGP HindIII polymorphism on FPG variation (p = 0.013), although the BGP HindIII polymorphism was not shown to be individually associated with FPG. CONCLUSION The PvuII polymorphism of the ER-α gene and its potential interaction with the HindIII polymorphism of the BGP gene were associated with FPG in pre-menopausal Chinese women.

Abstract
Background: We conducted a population-based cohort study to assess whether tamoxifen treatment is associated with an increased incidence of diabetes. Methods: Data obtained from the Taiwanese National Health Insurance Research Database were used for a population-based cohort study. The study cohort included 22 257 breast cancer patients diagnosed between 1 January 2000 and 31 December 2004. Among them, 15 210 cases received tamoxifen treatment and 7047 did not. Four subjects without breast cancer were frequency-matched by age and index year as the control group. Hazard ratios (HRs) and 95% confidence intervals (CIs) were estimated using multivariate Cox proportional hazards regression analysis. Results: Breast cancer patients exhibited a 14% higher rate of developing diabetes (adjusted HR=1.14, 95% CI=1.08–1.20) compared with non-breast cancer controls, but the significant difference was limited to tamoxifen users. In addition, tamoxifen users exhibited a significantly increased risk of diabetes compared with non-tamoxifen users among women diagnosed with breast cancer (adjusted HR=1.31, 95% CI=1.19–1.45). Stratification by age groups indicated that both younger and older women diagnosed with breast cancer exhibited a significantly higher risk of diabetes than the normal control subjects did, and tamoxifen users consistently exhibited a significantly higher diabetes risk than non-tamoxifen users or normal control subjects did, regardless of age. Both recent and remote uses of tamoxifen were associated with an increased likelihood of diabetes. Conclusions: The results of this population-based cohort study suggested that tamoxifen use in breast cancer patients might increase subsequent diabetes risk. The underlying mechanism remains unclear and further larger studies are mandatory to validate our findings.

Abstract
OBJECTIVE Variants of estrogen receptor α (ERα) have been associated with obesity, dyslipidemia, diabetes and blood pressure. The Middle East registers some of the highest rate of metabolic syndrome worldwide. The aim of this study is to investigate the relationship between metabolic syndrome, a clustered combination of these metabolic factors, and polymorphisms PvuII and XbaI of ERα in Lebanese Caucasian elderly overweight subjects. MATERIAL/METHODS 250 Caucasian Lebanese unrelated elderly men and women, median age 71 years, were studied. ERα intronic polymorphisms variants, PvuII and XbaI diplotypes and genotypes, were examined. Associations with metabolic syndrome, defined by the American Heart Association/National Heart, Lung, and Blood Institute (AHA/NHLBI), and its components, namely high density lipoprotein (HDL), fasting glucose levels, blood pressure, and waist circumference were evaluated in regression models. RESULTS ER α diplotypes and genotypes distributions were similar between participants with and without metabolic syndrome, in the overall group of subjects, and by gender. No consistent associations between the diplotypes and genotypes tested and metabolic syndrome, or its components, could be detected. CONCLUSIONS Genetic variants in ERα were not associated with metabolic syndrome or its components, in a group of 250 Lebanese Caucasian elderly participants, a group with a high prevalence of metabolic syndrome.

In the present study, we assessed the association of estrogen receptor-alpha gene polymorphisms (XbaI and PvuII) with metabolic syndrome and its related phenotypes. MATERIALS/METHODS One hundred and fifty Egyptian female patients with metabolic syndrome (mean age 35.52±6.86) were compared with one hundred and fifty age matched healthy Egyptian women (controls). The component traits of metabolic syndrome were determined, and the XbaI and PvuII genotypes were assessed with the PCR-RFLP method. RESULTS Our data indicated a significant difference in the allele frequencies of XbaI, but not PvuII, between the metabolic syndrome and control groups (P=0.0003 and P=0.164). Carriers of the minor alleles of XbaI and PvuII gene polymorphisms, in either the homozygous or heterozygous form, were associated with high diastolic blood pressure, high total cholesterol and LDL-c levels, increased HOMA-IR values and decreased QUICKI values compared to carriers of the major allele. However, only the minor G allele of XbaI was associated with measures of adiposity, specifically, BMI and waist circumference. CONCLUSIONS The XbaI polymorphism of the estrogen receptor alpha gene is associated with metabolic syndrome. On the other hand, PvuII gene polymorphism is not associated with the occurrence of the disease in this sample of Egyptian women.

Abstract
BACKGROUND Estrogen plays a fundamental role in the pathogenesis of type 2 diabetes mellitus (T2DM). Very few studies have shown the association between estrogen receptor α (ERα), PvuII and XbaI gene polymorphisms with T2DM in both men and women. We evaluated the hypothesis that PvuII and XbaI polymorphisms of ERα gene may be associated with T2DM in adult. METHODS From spring of 2010 to the fall of 2011, a case-control study was performed at clinical centers of Jahrom University of Medical Sciences. We included 174 patients with T2DM including men and women and 174 age, sex, and body mass index frequency-matched health controls. We analyzed the PvuII and XbaI polymorphisms of ERα by using the polymerase chain reaction-based restriction fragment length polymorphism method. RESULTS No significant differences between demographic characteristics of control and patients groups were observed. Allele frequencies of both PvuII and XbaI polymorphisms were significantly different between patients and control subjects (P=0.014 vs. P=0.002, respectively). When the group was separated into women and men, logistic regression analysis of genotype distribution of PvuII (pp vs. Pp+PP) in both sexes revealed that there was no significant association of PvuII genotype with men (odds ratio [OR], 1.67; confidence interval [CI], 0.86 to 3.28; P=0.89) and women (OR, 0.96; CI, 0.53 to 1.74; P=0.12). CONCLUSION PvuII and XbaI polymorphisms in ERα are related with T2DM in the inpatient population.

Abstract
Background Many genetic studies, including single gene studies and Genome-wide association studies (GWAS), aim to identify risk alleles for genetic diseases such as Type II Diabetes (T2D). However, in T2D studies, there is a significant amount of the hereditary risk that cannot be simply explained by individual risk genes. There is a need for developing systems biology approaches to integrate comprehensive genetic information and provide new insight on T2D biology. Methods We performed comprehensive integrative analysis of Single Nucleotide Polymorphisms (SNP's) individually curated from T2D GWAS results and mapped them to T2D candidate risk genes. Using protein-protein interaction data, we constructed a T2D-specific molecular interaction network consisting of T2D genetic risk genes and their interacting gene partners. We then studied the relationship between these T2D genes and curated gene sets. Results We determined that T2D candidate risk genes are concentrated in certain parts of the genome, specifically in chromosome 20. Using the T2D genetic network, we identified highly-interconnected network "hub" genes. By incorporating T2D GWAS results, T2D pathways, and T2D genes' functional category information, we further ranked T2D risk genes, T2D-related pathways, and T2D-related functional categories. We found that highly-interconnected T2D disease network “hub” genes most highly associated to T2D genetic risks to be PI3KR1, ESR1, and ENPP1. The well-characterized TCF7L2, contractor to our expectation, was not among the highest-ranked T2D gene list. Many interacted pathways play a role in T2D genetic risks, which includes insulin signalling pathway, type II diabetes pathway, maturity onset diabetes of the young, adipocytokine signalling pathway, and pathways in cancer. We also observed significant crosstalk among T2D gene subnetworks which include insulin secretion, regulation of insulin secretion, response to peptide hormone stimulus, response to insulin stimulus, peptide secretion, glucose homeostasis, and hormone transport. Overview maps involving T2D genes, gene sets, pathways, and their interactions are all reported. Conclusions Large-scale systems biology meta-analyses of GWAS results can improve interpretations of genetic variations and genetic risk factors. T2D genetic risks can be attributable to the summative genetic effects of many genes involved in a broad range of signalling pathways and functional networks. The framework developed for T2D studies may serve as a guide for studying other complex diseases.

Abstract
BACKGROUND Hyperuricemia is associated with obesity. Few studies have reported the effects of different types of bariatric surgery on uric acid metabolism. The aim of our study was to determine the relationships between serum uric acid reduction and estrogen receptor-α (ESR1) gene polymorphism, as well as the type of bariatric surgery received. The potential physiological pathways involved in postsurgery serum uric acid reduction were also discussed. METHODS A total of 508 severely obese Han Chinese patients, aged 20 to 50 years, with a body mass index (BMI)≥35 kg/m(2) were selected. Patients received either laparoscopic adjustable gastric banding (LAGB; n = 164) or laparoscopic mini-gastric bypass (LMGB; n = 344). A 12-month follow-up was performed to explore the effects of the type of bariatric surgery and ESR1 polymorphism on serum uric acid reduction. RESULTS The rs712221 polymorphism of ESR1 affects serum uric acid reduction after bariatric surgery. The LMGB group exhibited a greater reduction in serum uric acid level compared with the LAGB counterpart after adjusting for sex, age, and metabolic confounders (-2.3 ± 2.1 mg/dL versus-1.2 ± 1.1 mg/dL; P = .002). Patients with the rs712221 genotype exhibited better glycemic control and a greater serum uric acid reduction at 12 months after surgery. The effects of the rs712221 polymorphism in LMGB patients resulted in the greatest serum uric acid reduction (-2.7 ± 1.4 mg/dL). CONCLUSIONS For severely obese Han Chinese patients, bariatric surgery appears to reduce serum uric acid levels, potentially mediated by synergic effects of surgery type, BMI reduction, rs712221 locus, insulin sensitivity, and changed dietary factors via an unknown mechanism.

Abstract
BACKGROUND Significant variability in weight loss and glycemic control has been observed in obese patients receiving bariatric surgery. Genetic factors may play a role in the different outcomes. METHODS Five hundred and twenty severely obese patients with body mass index (BMI) ≥35 were recruited. Among them, 149 and 371 subjects received laparoscopic adjustable gastric banding (LAGB) and laparoscopic mini-gastric bypass (LMGB), respectively. All individuals were genotyped for five obesity-related single nucleotide polymorphisms on ESR1, FTO, PPARγ, and UCP2 genes to explore how these genes affect weight loss and glycemic control after bariatric surgery at the 6th month. RESULTS Obese patients with risk genotypes on rs660339-UCP2 had greater decrease in BMI after LAGB compared to patients with non-risk genotypes (-7.5 vs. -6 U, p = 0.02). In contrast, after LMGB, obese patients with risk genotypes on either rs712221-ESR1 or rs9939609-FTO had significant decreases in BMI (risk vs. non-risk genotype, -12.5 vs. -10.0 U on rs712221, p = 0.02 and -12.1 vs. -10.6 U on rs9939609, p = 0.04) and a significant amelioration in HbA1c levels (p = 0.038 for rs712221 and p < 0.0001 for rs9939609). The synergic effect of ESR1 and FTO genes on HbA1c amelioration was greater (-1.54%, p for trend <0.001) than any of these genes alone in obese patients receiving LMGB. CONCLUSIONS The genetic variants in the ESR, FTO, and UCP2 genes may be considered as a screening tool prior to bariatric surgery to help clinicians predict weight loss or glycemic control outcomes for severely obese patients.

Abstract
Type 2 diabetes mellitus (DM) is a multifactorial disease where both genetic and environmental factors contribute to its pathogenesis. Estrogen plays an important role in type 2 DM pathogenesis. A number of polymorphisms have been reported in the estrogen receptor (ESR1), including the XbaI and PvuII restriction enzyme polymorphisms of ESR1,which may be involved in disease pathogenesis. Metallothioneins (MT) act as potent antioxidants against various oxidative damages. Very few studies have indicated the association between Estrogen Receptor-α, MT1 gene polymorphisms with type2 DM. A total of 100 type 2 diabetic women and 100 age, sex matched controls were recruited. Using the PCR based RFLP method, the PvuII and XbaI polymorphisms of ESR1 and in MT1A (rs8052394 and rs11076161) gene polymorphisms were analysed. The genotype distribution and frequency of mutated allele showed no significant differences between diabetic and non-diabetic groups in PvuII (χ2 = 2.443; P = 0.1181) or XbaI (χ2 = 1.789; P = 0.1812) and rs8052394 (χ2 = 1.154; P = 0.2840) or rs11076161 (χ2 = 0.4141; P = 0.5199), polymorphisms. This is the first Indian study to conclude that ESR1 and MT1 gene polymorphisms are not associated with increased susceptibility to type 2 diabetes in Indian women.

Abstract
The PvuII and XbaI polymorphisms of the estrogen receptor α (ER1) gene have been variably associated with type 2 diabetes (T2D) in several populations. However, this association has not been studied in Iranian subjects and we hypothesized that the ER1 variants might be associated with T2D and related metabolic traits in this population. The PvuII and XbaI genotypes were determined by PCR-RFLP in 377 normoglycemic controls and 155 T2D patients. Bonferroni correction was applied for the correction of multiple testing. No significant association was found between the allele and genotype frequencies of PvuII and XbaI variants with T2D in females. In a dominant model (PP vs. Pp+pp), the frequency of the Pp+pp genotype was higher in normoglycemic subjects compared to T2D patients [85.5% vs. 66.7%, OR 0.22 (0.08-0.55), P=0.001]. Four possible haplotypes were observed in the population, whereas haplotype TA had a higher frequency in male T2D subjects than the controls. Furthermore, non-diabetic male subjects carrying the genotype of PP had a higher fasting glucose levels than the individuals with the genotype of Pp+pp (P=0.013). Multivariate logistic regression analysis showed that PvuII polymorphism was the independent determinants of T2D in males [OR 4.37 (1.61-11.86), P=0.004]. No association was found between the XbaI polymorphism and diabetes in male group. Our results suggest that the ER1 polymorphisms might associate with T2D and fasting glucose among Iranian male subjects.

Abstract
Although estrogen is primarily thought of as the hormone involved in female reproduction, it also plays a role in many additional physiological and pathological processes. Recent studies have demonstrated an association between estrogen and clustered risk factors for cardiovascular disease (CVD), such as lipid and glucose metabolism and obesity-related phenotypes, as well as occurrence and severity of CVD. Evidence suggesting a genetic basis for this link is accumulating. Several polymorphisms of the estrogen receptor (ER) alpha (ESR1) gene exist that may influence the impact of estrogen, leading to clinically relevant phenotypes. Based on the relationship ERS1 seems to exhibit with CVD risk factors, these polymorphisms may play a role in the mediation of vasoprotective effects, modulation of cardiovascular physiology, and development of risk factors for CVD. The two most frequently studied polymorphisms located in ESR1 are often identified by their restriction endonucleases Pvull (rs2234693) and Xbal (rs9340799). ln this review, we have evaluated and summarized the results of studies involving rs2234693 and rs9340799 and clustered risk factors accompanying development of CVD. Despite inconsistent findings, together these studies provide some support for a relationship between polymorphisms in ESR1 and risk factors for CVD. These summarized findings do not yet support inclusion of ESR1 genotypes in genetic testing algorithms for predisposition to CVD, but they do indicate that further investigation into the potential connection between ESR1 and risk factors for CVD is warranted.

Abstract
BACKGROUND Data on the association between sex hormone receptor polymorphisms and migraine are conflicting. METHODS We performed a systematic review and meta-analysis on this topic searching for studies published until August 2009. For each study, we calculated odds ratios (ORs) and 95% confidence intervals (CIs) assuming additive, dominant, and recessive genetic models. We then calculated pooled ORs and 95% CIs. RESULTS AND CONCLUSION Among the seven genes targeted, four variants were investigated in multiple studies. Effect estimates from an additive model suggest that the ESR-1 594 G>A (pooled OR 1.37; 95% CI 1.02-1.83) and ESR-1 325 C>G (pooled OR 1.16; 95% CI 1.03-1.32) variants are associated with any migraine. This pattern does not differ between migraine with and without aura. In contrast, the ESR-1 Pvu II C>T and PGR PROGINS insert polymorphism do not appear to be associated with migraine. Results were driven by studies among Caucasians and may differ in other ethnic groups.

Abstract
We aimed to explore the single-locus, haplotype and epistasis patterns and the contribution of oestrogen receptor [ESR1 PvuII (rs2234693), ESR1 325 C→G (rs1801132)] and progesterone receptor [PROGINS (rs1042838)] polymorphisms in genetic susceptibility to migraine by analysing 613 subjects consisting of 217 migraine patients, 217 healthy controls (HC) and 179 patients with tension-type headache (TTH). Entire data were analysed by taking the Bonferroni corrected P-value into account. We found significant association of TT genotype [odds ratio (OR) 3.458, confidence interval (CI) 1.757, 6.806; P = 0.0003] and T allele (OR 1.729, CI 1.309, 2.284; P = 0.0001) of ESR1 PvuII single nucleotide polymorphism with migraine when compared with HC. Significant association was seen only in female migraine patients at both genotype (P = 0.002; OR 3.834, CI 1.625, 9.043) and allele level (P = 0.002; OR 1.721, CI 1.228, 2.413). Moreover, higher risk was limited to migraine with aura (MA) (in case of TT genotype, P = 0.002; OR 4.377, CI 1.703, 1.246; in case of T allele, P = 0.001; OR 1.888, CI 1.305, 2.735) rather than migraine without aura (MoA) (P-value of TT genotype = 0.003; OR 3.082, CI 1.465, 6.483; P-value T allele = 0.002; OR 1.630, CI 1.188, 2.236). In case of a recessive model, risk was seen with migraine patients (P = 0.0003; OR 2.514, CI 1.635, 3.867), MA (P = 0.0001; OR 3.583, CI 1.858, 6.909) and MoA patients (P = 0.002; OR 2.125, CI 1.304, 3.464) when compared with HC. No risk was observed when TTH patients were compared with HC. No significance of ESR 325 G→C polymorphism was seen in any of the models under study. Significant differences in genotypic (P = 0.0001) and allelic frequency (P = 0.0002) were seen in case of PROGINS polymorphism when migraine patients were compared with HC, showing a protective effect (for A1A2 genotype, OR 0.292, CI 0.155, 0.549; for A2 allele, OR 0.320, CI 0.174, 0.589). Moreover, significance was seen only in case of female migraine patients at genotype (P = 0.002; OR 0.344, CI 0.176, 0.684) as well as allele levels (P = 0.004; OR 0.379, CI 0.198, 0.727) in case of PROGINS polymorphism. ESR1 PvuII TT*ESR1 325 C→G CG genotype, PROGINS A1A2*ESR1 325 C→G CG genotype and ESR1 PvuII CT*PROGINS A1A2 interacted significantly, but significance was lost after Bonferroni correction. In conclusion, ESR1 PvuII polymorphism is a significant risk factor for migraine particularly in women and MA patients, but ESR 325 C→G polymorphism is not associated with migraine susceptibility. PROGINS polymorphism seems to play a protective role in genetic susceptibility to migraine in the North Indian population.

Abstract
Residual feed intake (RFI) is a measure of feed efficiency, in which low RFI denotes improved feed efficiency. Caloric restriction (CR) is associated with feed efficiency in livestock species and to human health benefits, such as longevity and cancer prevention. We have developed pig lines that differ in RFI, and we are interested in identifying the genes and pathways that underlie feed efficiency. Prepubertal Yorkshire gilts with low RFI (n = 10) or high RFI (n = 10) were fed ad libitum or fed at restricted intake of 80% of maintenance energy requirements for 8 days. We measured serum metabolites and hormones and generated transcriptional profiles of liver and subcutaneous adipose tissue on these animals. Overall, 6,114 genes in fat and 305 genes in liver were differentially expressed (DE) in response to CR, and 311 genes in fat and 147 genes in liver were DE due to RFI differences. Pathway analyses of CR-induced DE genes indicated a dramatic switch to a conservation mode of energy usage by down-regulating lipogenesis and steroidogenesis in both liver and fat. Interestingly, CR altered expression of genes in immune and cell cycle/apoptotic pathways in fat, which may explain part of the CR-driven lifespan enhancement. In silico analysis of transcription factors revealed ESR1 as a putative regulator of the adaptive response to CR, as several targets of ESR1 in our DE fat genes were annotated as cell cycle/apoptosis genes. The lipid metabolic pathway was overrepresented by down-regulated genes due to both CR and low RFI. We propose a common energy conservation mechanism, which may be controlled by PPARA, PPARG, and/or CREB in both CR and feed-efficient pigs.

Abstract
BACKGROUND A large number of potential obesity loci have been reported. At least 18 genes have been replicated in a minimum of 5 studies on obesity-related phenotypes. Fourteen additional genes have been associated with obesity in Asians. OBJECTIVES Our objectives were to examine how many common variants of these candidate genes are associated with severe obesity in Han Chinese and how they are combined to exert their effects. DESIGN In total, 304 severely obese patients [body mass index (BMI; in kg/m(2)) > or =39] and 304 control subjects (BMI < or = 24) participated in a 2-staged association study. Subsequently, 220 additional severely obese patients (BMI > or = 35) and 338 controls (BMI < or = 24) were recruited to replicate the results. All of the controls were age-, sex-, education- and residence-matched. Finally, a pooled analysis was carried out based on all 514 cases and 606 controls with complete information. RESULTS The first-stage association analysis in 94 cases and 94 controls found 18 potentially associated single nucleotide polymorphisms (SNPs) (P = 0.01-0.1). The significance of 3 novel common SNPs, 1 on ESR1 and 2 on PPARgamma, were confirmed in the second stage and replicated further with odds ratios ranging from 1.89 to 2.24. The combined effect of these 3 genes was stronger (odds ratio: 5.27; 95% CI: 2.25, 12.32) than that from any individual gene. CONCLUSIONS Severe obesity in Han Chinese was associated with 3 novel common SNPs for ESR1 and PPARgamma. These 2 genes collectively result in a >5-fold risk of severe obesity. This information may contribute to the assessment of risk of severe obesity.

Abstract
BACKGROUND Genetic variation of the estrogen receptor alpha (ESR1) and beta (ESR2) has been associated with components of the metabolic syndrome. METHODS The relationships of two ESR1 (rs2234693 and rs9340799) and three ESR2 (rs1271572, rs1256049, and rs4986938) polymorphisms with the metabolic syndrome were examined in 532 Caucasian female participants (median age 63.1 years) in the Women's Health Study. Most women (99.1%) were postmenopausal. The associations between ESR1 and ESR2 genotypes and haplotypes with the metabolic syndrome were evaluated. Effect modification by hormone therapy was also assessed. RESULTS Genotype and haplotype distributions were similar between women with and without metabolic syndrome. We found no consistent associations between the genotypes and haplotypes tested and the metabolic syndrome, or its components, in logistic regression models. No effect modification by hormone therapy use was noted. CONCLUSIONS No association between these genetic variants in ESR1 and ESR2 and the metabolic syndrome was observed among these Caucasian women. Further investigation regarding the potential involvement of estrogen receptor genes and the metabolic syndrome may be warranted in other ethnic groups.

Lipid profile and inflammatory markers associated with estrogen receptor alpha PvuII and XbaI gene polymorphisms. Transl Res 2009; 153:288-95.

Abstract
Estrogen is established to influence lipoprotein metabolism and inflammatory markers. Alternations in estrogen receptor alpha (ESR1) expression and function may affect the role of estrogen in this regard. The aim of this study was to determine whether ESR1 PvuII and XbaI gene polymorphisms have effects on lipoprotein (a) as well as inflammatory variables in an Iranian population. Three hundred and ninety seven consecutive participants (228 men, 57.4%) who were admitted at our center for elective coronary angiography because of symptoms related to coronary artery disease (CAD) were enrolled in our study. Total cholesterol, high-density lipoprotein (HDL)-cholesterol, and triglyceride levels were determined by standard methods using commercial kits. Low-density lipoprotein (LDL)-cholesterol was calculated according to the Friedewald formula. The lipoprotein (a) levels were measured by ELISA method using Biopool kit, and the CRP concentrations were determined by Latex Immunoturbidometry. The presence of PvuII and XbaI polymorphisms within the ESR gene were analyzed using polymerase chain reaction-based restriction fragment length polymorphism (PCR-RFLP). The frequency of homozygous and heterozygous were 25.9% and 50.1%, for PvuII genotypes, and the frequency was 23.7% and 48.6%, for XbaI genotypes, respectively. After adjusting for CAD and age, no impacts of ESR1 PvuII and XbaI polymorphisms were found on lipid profile, lipoprotein (a) level, and quantitative CRP either in total population or in subgroups stratified by gender. In conclusion, our data demonstrate that ESR1 PvuII and XbaI gene polymorphisms did not seem to have an effect on lipoprotein metabolism or on inflammatory variables such as CRP.

Abstract
Transcriptional profiling coupled with blood metabolite analyses were used to identify porcine genes and pathways that respond to a fasting treatment or to a D298N missense mutation in the melanocortin-4 receptor (MC4R) gene. Gilts (12 homozygous for D298 and 12 homozygous for N298) were either fed ad libitum or fasted for 3 days. Fasting decreased body weight, backfat, and serum urea concentration and increased serum nonesterified fatty acid. In response to fasting, 7,029 genes in fat and 1,831 genes in liver were differentially expressed (DE). MC4R genotype did not significantly affect gene expression, body weight, backfat depth, or any measured serum metabolite concentration. Pathway analyses of fasting-induced DE genes indicated that lipid and steroid synthesis was downregulated in both liver and fat. Fasting increased expression of genes involved in glucose sparing pathways, such as oxidation of amino acids and fatty acids in liver, and in extracellular matrix pathways, such as cell adhesion and adherens junction in fat. Additionally, we identified DE transcription factors (TF) that regulate many DE genes. This confirms the involvement of TF, such as PPARG, SREBF1, and CEBPA, which are known to regulate the fasting response, and implicates additional TF, such as ESR1. Interestingly, ESR1 controls several fasting induced genes in fat that are involved in cell matrix morphogenesis. Our findings indicate a transcriptional response to fasting in two key metabolic tissues of pigs, which was corroborated by changes in blood metabolites, and the involvement of novel putative transcriptional regulators in the immediate adaptive response to fasting.

Gender-specific effect of estrogen receptor-1 gene polymorphisms in coronary artery disease and its angiographic severity in Chinese population. Clin Chim Acta 2008; 395:130-3.

Abstract
BACKGROUND The role of common polymorphisms of the estrogen receptor-1 in coronary artery disease (CAD) and it association with angiographic severity reminds conflicting in sexes and different races. METHODS Two-hundred ten angiographically defined Chinese CAD patients and 174 control subjects were enrolled. DNA was obtained and the polymorphisms were analyzed by the polymerase chain reaction. The region containing the PvuII T/C and the XbaI A/G sites was amplified. PCR product was cleaved with the restriction endonucleases. RESULTS No significant differences in PvuII and XbaI genotype and allele frequencies were noted between the CAD and controls.However, when stratified by gender, we noticed the PvuII genotype and allele frequencies were significantly different between CAD and controls, but in male group only, not in female group. Diabetes, hypertension, high LDL levels and the PvuII CC genotype were independent risk factors for CAD. PvuII CC was associated with the angiographic severity of CAD measuring by the number of diseased vessels as well. For XbaI, no association was found with the CAD susceptibility before and after gender stratification. CONCLUSION This study revealed a gender-specific effect of PvuII polymorphism in Chinese CAD subjects. PvuII gene polymorphisms affect CAD susceptibility in man only. The PvuII CC is a risk factor for CAD and it is associated with angiographic CAD severity.

Abstract
BACKGROUND Estrogen is known to affect lipoprotein metabolism, the haemostatic system and inflammatory markers. Our aim was to determine whether estrogen receptor alpha (ESR1) PvuII and XbaI gene polymorphisms can influence lipid, haemostatic and inflammatory variables in healthy Caucasian women and men of reproductive age. METHODS 58 healthy women (aged between 18 and 45 years) and 55 healthy men (aged between 21 and 45 years) of reproductive age were enrolled in our study. FSH levels, lipid (total cholesterol, triglyceride, HDL cholesterol, lipoprotein(a), apo A-I, apo B), haemostatic (prothrombin time, activated partial thromboplastin time (aPTT), thrombin time, fibrinogen, factor V, VII, VIII, protein C, protein S, antithrombin III) and inflammatory (CRP) variables were measured on autoanalyzers using commercially available kits. Serum VLDL and LDL cholesterol concentrations were calculated with the equation of Friedewald. The ESR1 PvuII and XbaI genotypes were determined with PCR-RFLP method. RESULTS In the total group, the ESR1 XbaI GG genotype carriers had significantly higher serum lipoprotein(a) concentrations than the AA or AG genotype carriers. Serum total cholesterol concentrations were significantly higher in healthy women with the PvuII CC genotype than in those with the TT or TC genotypes, whereas healthy women with the GG genotype of the ESR1 XbaI polymorphism had significantly higher serum total cholesterol and LDL cholesterol levels compared to those with the AA or AG genotypes. No other effects of the ESR1 PvuII and XbaI polymorphisms were found on the investigated lipid, haemostatic and inflammatory variables either in the total group or in women and men separately. CONCLUSIONS The ESR1 PvuII and XbaI gene polymorphisms seem to affect lipoprotein metabolism in healthy subjects of peak reproductive age. However, further studies are needed to determine the molecular mechanisms by which the two polymorphisms could influence serum lipid levels.
