AHSP inhibits cellular production of the reactive oxygen species. Reduced AHSP indicates reduced protection against oxidative stressors. Our objective was to investigate AHSP levels in recurrent miscarriage (RM). Trophoblast was collected from women of 10 weeks gestation: voluntary abortion controls (VA, n = 10); spontaneous first miscarriage with subsequent normal pregnancy (SMSN, n = 15) or with subsequent miscarriage (SMSM, n = 5); RM previously investigated (RMPS, n = 5) or not previously investigated (RM, n = 5). AHSP mRNA and protein were determined using real-time quantitative polymerase chain reaction (PCR) and Western blot, respectively. One-way ANOVA was performed to assess statistical significance (p < 0.05). ahsp mRNA levels were maximally reduced in RM and RMPS (8.0 × 10−6 ± 1.3 and 8.1 × 10−6 ± 0.7, respectively) compared with SMSN and VA (16.1 × 10−6 ± 2.3 and 26.1 × 10−6 ± 2.7, respectively). SMSM showed levels significantly reduced as well (9.0 × 10−6 ± 2.3). In RM, a reduced defense from oxidative stressors is evident at first miscarriage, identifying women at high risk for subsequent eventful pregnancy. Reduced AHSP may identify women at risk of experiencing further miscarriages. Monica Emanuelli and Monia Cecati contributed equally to this paper.  相似文献

Although the polymorphic heterochromatin regions of chromosomes (heteromorphisms) have been extensively studied for their phenotypic effects on humans, co-occurrences of chromosome 1, 9, 16 and Y heteromorphisms and of acrocentric variants have never been studied on humans with an objective scoring system. Here we compared the frequencies of individual heteromorphisms on a total of 602, 768 and 224 patients with the indications of infertility, recurrent miscarriage and in vitro fertilization (IVF) failure, respectively and on 272 controls. Then we examined whether there were significant co-occurrences between heteromorphisms within and between the groups. There were no statistically significant differences in the frequencies of heteromorphisms between the groups. Both statistically significant and non-significant correlations were observed within the non-acrocentric and certain acrocentric heteromorphisms in each group. When these co-occurrences were examined between the groups, a 2.2 fold increased risk of IVF failure in males in the presence of either chromosome 13 or chromosome 21 variants was observed (95 %CI:1.1–4.2). We conclude that the simultaneous manifestations of heteromorphisms have no effect on reproductive failure. There seems to be a correlation between the non-acrocentric heteromorphisms (1qh+, 9qh+, 16qh + and Yqh+/-), which might be the result of complex interactions of formation of these heterochromatin regions. The correlations observed between certain acrocentric chromosomes might be related to satellite association and nucleolus formation. The increased risk observed in males with IVF failure in the presence of either chromosome 13 or 21 variants should be interpreted cautiously due to the heterogeneity of the group.  相似文献

Ghrelin has been found to be expressed in the human endometrium. Emerging evidence links ghrelin and its receptor with the reproductive system. Certain associations between ghrelin and angiogenesis have also been established. The aim of this small case-control study was to quantify and compare the expression of mRNA encoding ghrelin, ghrelin receptor (GHS-R), vascular endothelial growth factor A (VEGF A) and its receptors (VEGFR1-3) in the endometrium of women with recurrent miscarriage compared to parous controls. Correlations between the expression of particular genes were also investigated. Endometrial samples were obtained during the secretory phase of the menstrual cycle from 15 women with a history of recurrent miscarriage (first trimester pregnancy loss without a known cause) and 10 healthy parous controls. Ghrelin, GHS-R, VEGF A and VEGFR1-3 mRNA expression was analyzed by quantitative RT-PCR. The expression of mRNA for ghrelin and VEGF A was significantly higher in the study group than the control group. In the control group, the expression of ghrelin mRNA was positively correlated with the expression of VEGF A and VEGFR1 mRNA. In the study group, no such associations were observed. These results show that the expression of mRNA for ghrelin and VEGF A may be increased in the endometrium of women with recurrent miscarriage thus suggesting that ghrelin may play a role in the pathogenesis of recurrent miscarriage.  相似文献

Context

Recurrent miscarriage (RM), defined as three or more consecutive losses before the 20th week of gestation, affects 0.5–2% of pregnant women. In over 80% of cases, RM remains unexplained after investigations, suggesting the involvement of genetic factors.

Objectives

The present study investigates the common polymorphisms of chemokine receptors CCR5 (NG_012637.1:g.5303A>G) and CX3CR1 (NG_016362.1:g.21065C>T, Thr280Met and NG_016362.1:g.20971G>A, Val249Ile) and their association with recurrent miscarriages (RM) among north Indian women.

Participants and Methods

In a retrospective case-control study 200 well characterized patients with unexplained RM and 300 controls were genotyped for three polymorphic markers of CCR5 and CX3CR1 by restriction digestion of PCR amplified fragments.

Results

Alleles and genotypes of CX3CR1 Val249Ile revealed statistically significant associations with RM cases when compared with the controls. The homozygous variant genotype Ile/Ile was found to be significantly higher among patients (p = 0.0002) when compared with the homozygous wild type Val/Val genotype. The haplotype of CX3CR1 that carried major alleles of Thr280Met and Val249Ile (T-V) showed statistically significant protective association (p < 0.0001, OR = 0.41, 95% CI = 0.31–0.54). The haplotype A-T-V (all wild type alleles) revealed a statistically significant protective association (p < 0.0001, OR = 0.41, 95% CI = 0.34–0.62), whereas the haplotypes G-T-I, A-T-I and A-M-V modified the risk of RM 1.9-fold, 5.5-fold and 5.1-fold respectively.

Conclusions

A common polymorphism of CX3CR1 gene, Val240Ile is associated with the risk of RM in north Indian women. Risk of RM may also be modified by the presence of haplotypes T-I, M-V, G-T-I, A-T-I and A-M-V.  相似文献

Recurrent miscarriage (RM) occurs in approximately 1% of all couples trying to conceive. Most of the research about recurrent miscarriage mainly focuses on immunology. However, the roles of microRNAs plays (miRNAs) in RM remain elusive. Here, the function of miR-155-5p in regulating survival of human decidua stromal cells through NF-κB signaling was explored in RM. The quantitative real-time polymerase chain reaction (qRT-PCR) results showed that miR-155-5p was downregulated in both decidua tissues and serum from RM patients. While, the ELISA assay revealed that the overexpression of miR-155-5p reduced the inflammatory cytokines secretion including IL-6, IFN-γ, TNF-α and IL-10 in decidua stromal cells. The results of cell counting Kit8 (CCK-8) and immunofluorescence experiments suggested that transfection of miR-155-5p into decidua stromal cells can promote the growth and proliferation of cells. In addition, overexpression of miR-155-5p can also inhibit the apoptosis of decidua stromal cells. The western blot assay results demonstrated that the miR-155-5p exerted effect mainly through activating NF-κB signaling pathway in RM. In conclusion, the miRNA-155-5p can not only promote the growth and proliferation but also inhibit the apoptosis of decidua stromal cells depending on inhibiting NF-κB signaling pathway in recurrent miscarriage.  相似文献

Factor XII (FXII) deficiency is a rare genetic blood disorder. It can lead to a higher risk of developing deep vein thrombosis or acquired thrombotic disorders than the general population. This retrospective study evaluated patients who opted for surgery and were found to have abnormal clotting profiles and clotting factors on preoperative routine blood. Patients were included regardless of whether they were symptomatic or asymptomatic. The cohort comprised 115 patients with a mean FXII level of 128.04 ± 36.93%. Two (1.79%) patients, both of whom were women, had FXII levels <60%. The mean FXII level was 58 ± 1.41 (range, 57–59%) in this group. The present study shows the prevalence of FXII in the asymptomatic Saudi population. The results provide the normal range for FXII. The findings of our study provide the basis for diagnosing F XII deficiency in the asymptomatic Saudi population.  相似文献

Clinical pregnancies increasingly end in recurrent miscarriage (RM) during the first trimester, with genetic factors shouldering the main responsibility. MicroRNAs (miRNAs) regulate gene expression in a wide array of important biological processes. We examined the potential role of dysregulated miRNAs in RM pathogenesis and trophoblast development as an approach to elucidate the molecular mechanism behind RM. miRNA profiles from clinical specimens of RM and induced abortion (IA) were compared, and several miRNAs were found to be aberrantly expressed in RM samples. Among the miRNAs, miR‐365 was significantly differentially expressed in RM decidual tissues. Furthermore, our results demonstrate that miR‐365 functions as an upstream regulator of MDM2/p53 expression, cell cycle progression and apoptosis in trophoblasts. Bioinformatic prediction and experimental validation assays identified SGK1 as a direct target of miR‐365; consistently, its protein levels were low in decidual tissues. Additionally, functional studies revealed that SGK1 silencing elicits cell cycle arrest and apoptosis in trophoblasts and that SGK1 overexpression attenuates the effects of miR‐365 on apoptosis and MDM2/p53 expression. Collectively, our data provide evidence that the up‐regulation of miR‐365 may contribute to RM by decreasing SGK1 expression, which suggests its potential utility as a prognostic biomarker and therapeutic target for RM.  相似文献

Successful pregnancy in placental mammals substantially depends on the establishment of maternal immune tolerance to the semi-allogenic fetus. Disorders in this process are tightly associated with adverse pregnancy outcomes including recurrent miscarriage(RM). However, an indepth understanding of the systematic and decidual immune environment in RM remains largely lacking. In this study, we utilized single-cell RNA-sequencing(sc RNA-seq) to comparably analyze the cellular and molecular signatures of decidual and peripheral leukocytes in normal and unexplained RM pregnancies at the early stage of gestation. Integrative analysis identifies 22 distinct cell clusters in total, and a dramatic difference in leukocyte subsets and molecular properties in RM cases is revealed. Specifically, the cytotoxic properties of CD8+effector T cells, nature killer(NK), and mucosal-associated invariant T(MAIT) cells in peripheral blood indicates apparently enhanced pro-inflammatory status, and the population proportions and ligand–receptor interactions of the decidual leukocyte subsets demonstrate preferential immune activation in RM patients.The molecular features, spatial distribution, and the developmental trajectories of five decidual NK(d NK) subsets have been elaborately illustrated. In RM patients, a d NK subset that supports embryonic growth is diminished in proportion, while the ratio of another d NK subset with cyto-toxic and immune-active signature is significantly increased. Notably, a unique pro-inflammatory CD56+CD16+d NK subset substantially accumulates in RM decidua. These findings reveal a comprehensive cellular and molecular atlas of decidual and peripheral leukocytes in human early pregnancy and provide an in-depth insight into the immune pathogenesis for early pregnancy loss.  相似文献
