Abstract
BACKGROUND Recently, the roles of ESR1 and ESR2 polymorphisms in osteoporosis have been extensively reported, with conflicting findings. Therefore, we performed this present study to evaluate the potential associations between ESR1 and ESR2 polymorphisms and osteoporosis risk. METHODOLOGY All included literatures published up to April 2021 were identified by searching Pubmed, Embase, Web of Science, Cochrane Library, Chinese National Knowledge Infrastructure (CNKI) and Wanfang databases. Pooled odds ratio (OR) and 95% confidence interval (CI) were calculated the associations using a fixed or random effects model. RESULTS 36 observational studies involving five gene polymorphisms (ESR1 PvuII, ESR1 XbaI, ESR1 G2014A, ESR2 AluI and ESR2 RsaI) covering 12507 cases and 18487 controls were included. The results of our meta-analysis demonstrated the variant A allele of ESR2 RsaI polymorphism might play a remarkable protective role in developing osteoporosis under all genetic models. However, no associations were observed between ESR1 PvuII, ESR1 XbaI, ESR1 G2014A and ESR2 AluI polymorphisms with the risk of osteoporosis under all genetic models. CONCLUSIONS Our meta-analysis suggests that genetic polymorphism in ESR2 RsaI may lead to decreased risk for osteoporosis. Further larger studies are needed to confirm this conclusion.

Abstract
Background Postmenopausal osteoporosis (PMO) is the most common type of primary osteoporosis. ESR1 polymorphism rs2234693 and rs9340799 has been widely studied as a candidate gene associated with PMO, however, the findings were inconclusive. The present study aims to explore the relationship of ESR1 polymorphism rs2234693 and rs9340799 with PMO risk in a Chinese Han population. Methods PMO patients and healthy controls were recruited from gynecology department. DNA of all participants were extracted from the peripheral blood samples and genotyped by Mass Array method. A meta-analysis of case control studies was also conducted to further elucidate the relationship of polymorphism with PMO. Results Our results revealed that there were no associations of rs2234693 with PMO. However, GG genotype of rs9340799 was associated with a higher risk of PMO (OR = 1.51, 95%CI:1.08–4.34, p = 0.03), even adjusting for risk factors (OR = 1.83, 95%CI: 1.12–5.04, p = 0.04). Logistic regression analysis showed that dominant model was associated with a higher risk of PMO (OR = 2.07, 95%CI: 1.02–5.16, p = 0.02) after correcting the risk factors (OR = 2.14, 95%CI:1.12–5.64, p = 0.04); In addition, the Meta-analysis results revealed that both two polymorphisms were not associated with PMO. Conclusions In conclusion, ESR1 polymorphism rs9340799 was associated with PMO. However, well designed studies with larger sample sizes are required to further elucidate the associations.

Abstract
The importance of apolipoprotein E (APOE) in late-onset Alzheimer's disease (LOAD) has been firmly established, but the mechanisms through which it exerts its pathogenic effects remain elusive. In addition, the sex-dependent effects of APOE on LOAD risk and endophenotypes have yet to be explained. In this Review, we revisit the different aspects of APOE involvement in neurodegeneration and neurological diseases, with particular attention to sex differences in the contribution of APOE to LOAD susceptibility. We discuss the role of APOE in a broader range of age-related neurodegenerative diseases, and summarize the biological factors linking APOE to sex hormones, drawing on supportive findings from rodent models to identify major mechanistic themes underlying the exacerbation of LOAD-associated neurodegeneration and pathology in the female brain. Additionally, we list sex-by-genotype interactions identified across neurodegenerative diseases, proposing APOE variants as a shared etiology for sex differences in the manifestation of these diseases. Finally, we present recent advancements in 'omics' technologies, which provide a new platform for more in-depth investigations of how dysregulation of this gene affects the development and progression of neurodegenerative diseases. Collectively, the evidence summarized in this Review highlights the interplay between APOE and sex as a key factor in the etiology of LOAD and other age-related neurodegenerative diseases. We emphasize the importance of careful examination of sex as a contributing factor in studying the underpinning genetics of neurodegenerative diseases in general, but particularly for LOAD.

Abstract
The aim of this study was to perform a systematic review to identify data reported in the literature concerning the association of APOC3 (rs2854116), ESR2 (rs3020450), HFE (rs1799945), MMP1 (rs1799750) and PPARG (rs1801282) polymorphisms with lipodystrophy in people living with HIV (PLWHIV) on antirretroviral therapy. The research was conducted in six databases and the studies were selected in two steps. First, a search was undertaken in the following electronic databases: PubMed, Science Direct, Medline, World Wide Science, Directory of Open Access Journals, Scielo, Lilacs and Medcarib. The titles and abstracts of 24,859 articles were read to select those that match the elegibilty criteria. Five papers that addressed the association of HAART, lipodystrophy and polymorphisms were selected for the review. There was no association between the polymorphisms of the genes APOC3 and PPARG and lipodystrophy. Another study described an association between the variant allele (G) of HFE and protection concerning the development of lipoatrophy (0.02) when compared with the reference allele (C). On the other hand, the variant allele (T) of the ESR2 gene was associated with the development of lipoatrophy (p = 0.007) when compared with the reference allele (C). In addition, the genotype and the variant allele of the gene MMP1 (2G) were associated with lipodystrophy in PLWHIV on HAART (p = 0.0002 and p = 0.0008, respectively). Therefore, further studies with other populations, involving PLWHIV on HAART are necessary to better understand the role of genetic markers, which may be involved in a predisposition to lipodystrophy.

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.

Abstract
OBJECTIVES The aim of the study was to investigate the role of estrogen receptor type 2 gene (ESR2) variant G1730A in myocardial infarction (MI) in young age. METHODS Genotyping was performed with restriction fragments length polymorphism method in 158 patients (79.1% men) with MI aged <50 years (studied group) and in control groups: 150 healthy individuals aged <50 years (63.3% men) and 202 patients (64.3% men) with MI aged ≥50 years. RESULTS The AA genotype of ESR2 G1730A variant was significantly more frequent in men with MI aged <50 comparing to men with MI aged ≥50 (21.6% vs. 8.4%, P = 0.004) and to healthy young men (21.6% vs. 11.6%, P = 0.048). There was statistically significant difference between AA genotype and GA + GG genotypes male carriers with MI aged <50 in median triglyceride (TG) level (2.0 vs. 1.7 mmol/l respectively, p = 0.023). CONCLUSIONS Our findings suggest a possible role of ESR2 G1730A variant as the risk factor of MI in a young age not as an independent but a potential risk factor associated with TG level in men but not in women.

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
Metabolic syndrome (MetS) is a combination of metabolic disorders associated with an increased risk for cardiovascular disease (CVD). Studies in women reported associations between polymorphisms in ESR1, LPL and CETP genes and MetS. Our aim was to evaluate the association between variants in ESR1, LPL and CETP genes with MetS and its components. Four hundred and eighty women were analyzed, anthropometric features and biochemical profiles were evaluated, and genotyping was performed by real-time PCR. We found an association with elevated glucose levels (odds ratio (OR) = 2.9; p = 0.013) in carrying the AA genotype of rs1884051 in the ESR1 gene compared with the GG genotype, and the CC genotype of rs328 in the LPL gene was associated with MetS compared to the CG or GG genotype (OR = 2.8; p = 0.04). Moreover, the GA genotype of rs708272 in the CETP gene is associated with MetS compared to the GG or AA genotype (OR = 1.8; p = 0.006). In addition the ACTCCG haplotype in the ESR1 gene is associated with a decrease in the risk of MetS (OR = 0.02; p < 0.001). In conclusion, our results show the involvement of the variants of ESR1, LPL and CETP genes in metabolic events related to MetS or some of its features.

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.

Abstract
OBJECTIVE To investigate genetic single nucleotide polymorphisms (SNPs) in estrogen receptor-α (ERα) (ESR1, rs2234693, rs1801132, rs7757956 and rs2813544) and ERβ (ESR2, rs3020450, rs7154455 and rs4986938) genes and relate them to the adverse effects lipodystrophy, dyslipidemia and metabolic syndrome as well as to differences in their prevalence between sexes in HIV-infected individuals on HAART. DESIGN Cross-sectional study. METHODS Blood samples and anthropometric measurements were collected from 614 patients at reference services in the cities of Porto Alegre, Pelotas and Rio Grande in Brazil. The SNPs were genotyped by real-time PCR. RESULTS The lipodystrophy subtype frequencies in patients of different sexes showed statistically significant differences; the atrophic pattern was more prevalent in men, and the hypertrophic pattern was more prevalent in women. Furthermore, metabolic syndrome prevalence was higher in women than in men. The ESR1 rs2813544 G-allele was associated with higher measurements of several anthropometric variables in women: BMI, total subcutaneous fat and subcutaneous fat of limbs. Additionally, patients who were AA homozygous for ESR2 rs3020450 presented an increased risk for developing lipoatrophy (prevalence ratio 1.37, 95% confidence interval 1.09-1.73, P = 0.007). CONCLUSION Significant differences in lipodystrophy and metabolic syndrome prevalence were detected between sexes. Moreover, the ESR1 gene (rs2813544) presented significant sex-specific associations with anthropometric variables, and the ESR2 gene (rs3020450) was associated with an increased risk of developing lipoatrophy. Our results suggest that these genes are in part responsible for the sexual dimorphism in fat tissue redistribution and patterns of lipodystrophy.

Abstract
The metabolic syndrome is a complex condition characterized by obesity, insulin resistance, decreased high-density lipoproteins, and hypertension associated with high risk of developing type 2 diabetes and cardiovascular disease. A major increase in the incidence of developing metabolic syndrome and related diseases is observed worldwide in association with a change toward a less active lifestyle and increased food consumption. Estrogen and the estrogen receptors (ERs) are well-known regulators of several aspects of metabolism, including glucose and lipid metabolism, and impaired estrogen signaling is associated with the development of metabolic diseases. This review will describe the key effects of estrogen signaling in metabolic and glucose sensing tissues, including the liver, pancreatic β cells, adipose tissue, and skeletal muscle. The impact on metabolic processes of impaired estrogen signaling and knock out of each ER subtype will also be discussed.

Abstract
The objective of the present study was to explore a potential association between the estrogen receptor β (ERβ) gene polymorphisms and vascular dementia (VaD) in women. The relationship of two polymorphisms (rs944050 and rs4986938) and their associated haplotypes in the ERβ gene with VaD were examined in 121 Chinese Han women (>50 years of age) including 61 with VaD and 60 healthy age-matched controls. The potential associations were evaluated using unconditional logistic regression. The variant allele G of rs944050 in the ERβ gene increased the risk of VaD (odds ratio = 2.02, 95% confidence interval = 1.08-3.77). In haplotype analyses, the ERβ haplotype containing the polymorphism rs944050 variant allele and the polymorphism rs4986938 wild-type allele was associated with VaD (odds ratio = 1.70, 95% confidence interval = 1.03-2.84). The polymorphism rs944050 in the ERβ gene was associated with an increased risk of VaD in Chinese Han women. Further studies regarding the association between the ERβ gene polymorphisms and VaD are needed to confirm these findings.
