Abstract
The effect of estrogens is mediated by activation of estrogen receptors (ERs). Because ER-α gene polymorphisms may exert different effects in childhood, we analyzed the associations between the IVS1 −397T>C (PvuII) polymorphism and systemic inflammatory state, proangiogenic factors, frequency of monocyte subsets, lipid profile, blood pressure, and vascular complications in girls with type 1 diabetes mellitus (DM1). We examined 180 young girls with DM1 and 120 healthy age-matched controls. The analysis concerned PvuII polymorphism of the ER-α gene as well as the levels of serum inflammatory markers (CRP, IL-6, TNF-α), proangiogenic factors (VEGF, angiogenin), 17β-estradiol, values of monocyte subsets (CD14++CD16− and CD14+CD16+), lipid profile, and blood pressure. In our study, girls with CC genotype had lower level of inflammatory and angiogenic factors and lower frequencies of CD14+CD16+ monocytes in comparison to CT or TT carriers. Simultaneously, the CC carriers had a greater population of CD14++CD16− monocytes, increased blood pressure, and serum levels of: estrogen, total cholesterol, triglycerides, and low-density lipoprotein cholesterol than girls bearing CT or TT genotype. Our study suggests a pleiotropic effect of PvuII polymorphic CC variant on diabetic vasculopathies. Although the CC genotype carriers demonstrate less inflammatory and angiogenic activity, they seem to display less favorable cardiometabolic features. Based on our study, we cannot distinguish PvuII ER-α genotype that could be useful in identification of DM1 girls that are more prone to develop of late vascular complications, before the occurrence of first clinical symptoms.

Abstract
BACKGROUND AND AIMS The effect of estrogens is mediated by activation of estrogen receptors (ERs), which are expressed in many tissues. Because ER-α gene polymorphisms may exert different effects in childhood, in the present study we analyzed associations between the IVS1 -397T>C polymorphism and indicators of inflammatory response as well as late complications in boys with type 1 diabetes mellitus (DM1). METHODS AND RESULTS We examined 108 young boys with DM1 and 64 healthy age-matched control individuals. ER-α genotyping, as well as the CRP and IL-6 serum level and blood pressure, was analyzed. In our study boys with CC genotype had lower blood pressure and IL-6 and CRP serum levels. Similar results were obtained for DM1 boys with microvascular complications - the blood pressure and serum level of IL-6, but not CRP, were still lower in the CC patients. CONCLUSIONS Our findings suggest that the presence of -397T allele may indicate macro- and microvascular complications in DM1 boys, before the occurrence of first clinical symptoms.

Abstract
BACKGROUND In older postmenopausal women, high levels of endogenous estrogen have been related to adverse health outcomes including ischemic arterial disease (IAD). Whether estrogen receptor-α (ESR1) and -β (ESR2) polymorphisms modulate the effects of estrogens on IAD has not been investigated. METHODS In the Three-City prospective cohort study among subjects older than 65 years, we used a case-cohort design in which plasma levels of total and bioavailable 17β-estradiol were measured. After exclusion of postmenopausal women using hormone therapy, a random subcohort of 533 women and 105 incident cases of first IAD events over 4 years of follow-up were analyzed. Five common polymorphisms of ESR1 and ESR2 were genotyped. Hazard ratios (HRs) of IAD for a 1-SD increase in hormones levels by the genotypes were estimated from Cox models after adjustment for cardiovascular risk factors and a correction for multiple testing. We also investigated the role of hemostasis and inflammation as potential mediators. RESULTS Neither estrogens nor IAD risk was significantly associated with estrogen receptor polymorphisms. Overall, IAD risk increased with total estradiol [HR1.40, 95% confidence interval (CI) 1.11-1.77]. Stratified analysis by genotypes showed that total estradiol was positively related to IAD risk in women with ESR1 rs9340799-AA genotype but not in women with the AG/GG genotype (HR 1.62, 95% CI 1.22-2.17 and HR 1.03, 95% CI 0.81-1.30, respectively; P for interaction <.05). An additional adjustment for hemostatic variables reduced the HR by about one third in women carrying the rs9340799-AA genotype (HR 1.41, 95% CI 1.06-1.90). CONCLUSION The ESR1 rs9340799 genotype may modify the IAD risk related to high endogenous estrogens levels in older postmenopausal women. Hypercoagulability may act as a mediator.

Abstract
PURPOSE The study aimed to investigate the influence of estrogen receptor α (ER-α) genotypes on inflammatory response and development of microvascular complications in girls with type 1 diabetes. METHODS 152 young regularly menstruating girls with diagnosed type 1 diabetes and 84 young, healthy menstruating girls were recruited. ER-α genotyping was carried out by PCR. Serum concentrations of 17β-estradiol, as well as IL-6, TNF-α, VEGF, and IL-10, were measured. CD4(+)Foxp3(+) TH17 cells were isolated and analyzed by flow cytometry. RESULTS Type 1 diabetic girls carrying TT genotype were characterized by the lowest serum estradiol level and IL-10 and highest IL-6, TNF-α, and VEGF. The association between the level of certain cytokine and the genetic variant of estrogen receptor α polymorphism was analyzed. Frequencies of CD4(+)Foxp3(+) TH17 cells were also enhanced in TT bearing girls with type 1 diabetes and correlated with the level of analyzed cytokines. In addition, the correlation between serum estradiol level and cytokine concentrations was observed. CONCLUSIONS We propose that TT variant of estrogen receptor α polymorphism may be associated with enhanced inflammatory response, which in turn may lead to acceleration of diabetic retino- and nephropathy in girls with type 1 diabetes. This finding may help the physicians to predict the onset and progression of diabetic microvascular complications.

Abstract
BACKGROUND The role of estrogen receptor α (ERα) polymorphism in coronary artery disease (CAD) was investigated previously in several populations. There are few data on relation between ERa polymorphism and CAD in Chinese population. Our study was to investigate the possible association between ERα polymorphism and CAD in Chinese population. METHODS A total of 539 patients with CAD and 539 age and sex matched controls were examined for ERa polymorphism. DNA was obtained and ERa polymorphism was analyzed by the polymerase chain reaction-based restriction fragment length polymorphism (PCR-RFLP). RESULTS The frequencies of the PvuII C allele were significantly higher in CAD patients than in control individuals (P<0.05). Using T allele as a reference, the odds ratio for CAD patients with C allele was 1.24 (95%CI=1.03-1.48). Using TT genotype as a reference, the odds ratio for TC genotype was 1.17 (95%CI=0.90-1.50), and for CC genotype was 1.58 (95%CI=1.05-2.38). The odds ratio for CC genotype was 1.42 (95%CI=0.94-2.15) in women and 1.72 (95%CI=1.41-2.10) in men. There were no significant differences in XbaI allele and genotype between CAD patients and control individuals. CONCLUSIONS The ERa PvuII polymorphism is associated with the increased risk of CAD in men of a Chinese population. Further research is needed to investigate the mechanism underlying the association between ERα polymorphism and CAD.

Abstract
Type 1 diabetes is considered as pluricausal disease, whose etiology involves genetic predisposition as well as environmental factors that contribute to disease progression and pathogenesis. Women are believed to be more susceptible to develop autoimmune diseases, which may depend in part on the influence of sex hormones on the immune system. It was shown that estrogens may protect against the development of autoimmune disease by inducing the expansion of regulatory T cell pool and upregulating Foxp3 expression. Foxp3 is a transcription factor that controls the development and suppressive function of naturally occurring regulatory T cells CD4(+)Foxp3(+). Longstanding diabetes type 1 has features of low-grade chronic inflammation which may influence regulatory T cell subset by reducing their numbers or/and inhibiting their suppressive potential. As diabetic type 1 patients are differentiated with regard to metabolic factors, level of glycemic control and systemic inflammatory state, we aimed to examine if this can be associated with IVSI-397T>C estrogen receptor α polymorphism. We examined 93 young regularly menstruating girls with diagnosed type 1 diabetes and 49 healthy age-matched control individuals. The PvuII polymorphism of the ER-α gene was analyzed as well as the serum TNF level and the level of CD4(+)Foxp3(+) regulatory T cells in these individuals. Girls with type 1 diabetes had lower level of CD4(+)Foxp3(+) Tregs than their healthy counterparts. Regulatory T cells from these patients showed also lower expression of Foxp3 than Tregs in healthy, control group. In addition, DM1 girls bearing the CC genotypes showed the highest level of CD4(+)Foxp3(+) Tregs and the lowest TNF serum level in comparison to girls carrying CT or TT genotype. The CC DM1 carriers had also higher serum level of estrogens than girls bearing CT or TT genotype. We propose that different variants of IVS1-397 estrogen receptor α polymorphism may become additional genetic factor that influences regulatory conditions during diabetes type 1 in females.
