Xu XR, Cheng L, Wang YP. Prediction of severe preeclampsia and intrauterine growth restriction based on serum placental exosome miR-520a-5p levels during the first-trimester. Medicine (Baltimore) 2024; 103:e38188. [PMID: 38758859 PMCID: PMC11098175 DOI: 10.1097/md.0000000000038188] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/23/2024] [Accepted: 04/18/2024] [Indexed: 05/19/2024] Open
Abstract
BACKGROUND To assess the predictive capabilities of serum exosomal levels of micro-RNA-520a-5p (miR-520a-5p) concerning the occurrence of severe preeclampsia (sPE) and fetal growth restriction (FGR) during the first trimester of pregnancy. METHODS During the period spanning from October 2020 to October 2021, serum samples were procured from the first trimester and subsequently preserved by freezing at -80 ℃. These samples were obtained from 105 pregnant women in a nested case-control study. This cohort consisted of individuals who later developed sPE (sPE group, n = 35) and FGR (FGR group, n = 35) during the third trimester. Additionally, 35 women with normal blood pressure were denoted as normal pregnancy group. Serum samples from the first trimester were retrieved from all groups for further analysis after thawing. Exosomes were extracted from the serum samples collected during the first trimester and examined using transmission electron microscopy, western blot, and nanoparticle tracking analysis. Additionally, the determination of their placental origin was also established during the course of the study. Exosome miR-520a-5p levels were measured using real-time quantitative polymerase chain reaction assays, primarily involving quantitative reverse transcription polymerase chain reactions. Fetal placental tissues from the 3 groups were collected shortly after birth, and miR-520a-5p expression was measured using real-time quantitative polymerase chain reaction. Serum placental exosomes and fetal placental tissues were compared for miR-520a-5p levels. Placental trophoblasts were identified as the source of serum exosomes in all 3 groups. RESULTS It was found that serum placental exosomes exhibited lower levels of miR-520a-5p in both the sPE and FGR groups when compared to the normal pregnancy group. This finding was consistent with observations made in postpartum placental tissues. The predictive accuracy for sPE using miR-520a-5p levels in serum placental exosomes during the first trimester was notably higher (area under the receiver operating characteristic curve = 0.806, P <.05) compared to the prediction of FGR (area under the receiver operating characteristic curve = 0.628, P <.05). CONCLUSION Placenta-derived exosomes can be extracted from maternal serum during the first trimester of pregnancy and miR-520a-5p detected from the exosomes. The downregulation of miR-520a-5p serves as a more predictive indicator for the subsequent development of sPE compared to predicting FGR.

Abstract
Pre-eclampsia, which is part of the spectrum of hypertensive pregnancy disorders, poses a significant health burden, contributing to maternal and infant morbidity and mortality. Pre-eclampsia is widely associated with persistent adverse effects on the cardiovascular health of women with a history of pre-eclampsia. Additionally, there is increasing evidence demonstrating that offspring of pre-eclamptic pregnancies have altered cardiac structure and function, as well as different vascular physiology due to the decrease in endothelial function. Therefore, early detection of the likelihood of developing pre-eclampsia-associated cardiovascular diseases is vital, as this could facilitate the undertaking of the necessary clinical measures to avoid disease progression. The utilisation of microRNAs as biomarkers is currently on the rise as microRNAs have been found to play important roles in regulating various physiological and pathophysiological processes. In regard to pre-eclampsia, recent studies have shown that the expression of microRNAs is altered in postpartum women and their offspring who have been exposed to pre-eclampsia, and that these alterations may persist for several years. This review, therefore, addresses changes in microRNA expression found in postpartum women and offspring exposed to pre-eclampsia, their involvement in cardiovascular disease, and the potential role of microRNAs to be used as predictive tools and therapeutic targets in future cardiovascular disease research.

Preeclamptic programming unevenly perturbs inflammatory and renal vasodilatory outcomes of endotoxemia in rat offspring: modulation by losartan and pioglitazone. Front Pharmacol 2023; 14:1140020. [PMID: 37180728 PMCID: PMC10166818 DOI: 10.3389/fphar.2023.1140020] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/08/2023] [Accepted: 04/17/2023] [Indexed: 05/16/2023] Open
Abstract
Introduction: Preeclampsia (PE) enhances the vulnerability of adult offspring to serious illnesses. The current study investigated whether preeclamptic fetal programming impacts hemodynamic and renal vasodilatory disturbances in endotoxic adult offspring and whether these interactions are influenced by antenatal therapy with pioglitazone and/or losartan. Methods: PE was induced by oral administration of L-NAME (50 mg/kg/day) for the last 7 days of pregnancy. Adult offspring was treated with lipopolysaccharides (LPS, 5 mg/kg) followed 4-h later by hemodynamic and renovascular studies. Results: Tail-cuff measurements showed that LPS decreased systolic blood pressure (SBP) in male, but not female, offspring of PE dams. Moreover, PE or LPS reduced vasodilations elicited by acetylcholine (ACh, 0.01-7.29 nmol) or N-ethylcarboxamidoadenosine (NECA, 1.6-100 nmol) in perfused kidneys of male rats only. The latter effects disappeared in LPS/PE preparations, suggesting a postconditioning action for LPS against renal manifestation of PE. Likewise, elevations caused by LPS in serum creatinine and inflammatory cytokines (TNFα and IL-1β) as well as in renal protein expression of monocyte chemoattractant protein-1 (MCP-1) and AT1 receptors were attenuated by the dual PE/LPS challenge. Gestational pioglitazone or losartan reversed the attenuated ACh/NECA vasodilations in male rats but failed to modify LPS hypotension or inflammation. The combined gestational pioglitazone/losartan therapy improved ACh/NECA vasodilations and eliminated the rises in serum IL-1β and renal MCP-1 and AT1 receptor expressions. Conclusion: Preeclamptic fetal programming of endotoxic hemodynamic and renal manifestations in adult offspring depends on animal sex and specific biological activity and are reprogrammed by antenatal pioglitazone/losartan therapy.

Am J Reprod Immunol 2023; 89:e13670.

Abstract
Hypertensive disorders of pregnancy (HDP) are one of the commonest maladies, affecting 5%-10% of pregnancies worldwide. The American College of Obstetricians and Gynecologists (ACOG) identifies four categories of HDP, namely gestational hypertension (GH), Preeclampsia (PE), chronic hypertension (CH), and CH with superimposed PE. PE is a multisystem, heterogeneous disorder that encompasses 2%-8% of all pregnancy-related complications, contributing to about 9% to 26% of maternal deaths in low-income countries and 16% in high-income countries. These translate to 50 000 maternal deaths and over 500 000 fetal deaths worldwide, therefore demanding high priority in understanding clinical presentation, screening, diagnostic criteria, and effective management. PE is accompanied by uteroplacental insufficiency leading to vascular and metabolic changes, vasoconstriction, and end-organ ischemia. PE is diagnosed after 20 weeks of pregnancy in women who were previously normotensive or hypertensive. Besides shallow trophoblast invasion and inadequate remodeling of uterine arteries, dysregulation of the nonimmune system has been the focal point in PE. This results from aberrant immune system activation and imbalanced differentiation of T cells. Further, a failure of tolerance toward the semi-allogenic fetus results due to altered distribution of Tregs such as CD4+FoxP3+ or CD4+CD25+CD127(low) FoxP3+ cells, thereby creating a cytotoxic environment by suboptimal production of immunosuppressive cytokines like IL-10, IL-4, and IL-13. Also, intracellular production of complement protein C5a may result in decreased FoxP3+ regulatory T cells. With immune system dysfunction as a major driver in PE pathogenesis, it is logical that therapeutic targeting of components of the immune system with pharmacologic agents like anti-inflammatory and immune-modulating molecules are either being used or under clinical trial. Cholesterol synthesis inhibitors like Pravastatin may improve placental perfusion in PE, while Eculizumab (monoclonal antibody inhibiting C5) and small molecular inhibitor of C5a, Zilucoplan are under investigation. Monoclonal antibody against IL-17(Secukinumab) has been proposed to alter the Th imbalance in PE. Autologous Treg therapy and immune checkpoint inhibitors like anti-CTLA-4 are emerging as new candidates in immune horizons for PE management in the future.

Abstract
Prostaglandins participate in maternal recognition of pregnancy, implantation and maintenance of gestation. Prostaglandin transporter (PGT), as a candidate molecule of prostaglandin carriers, might be involved in the pathogenesis of preeclampsia. In preeclampsia (PE) patients' placental tissue, we identified PGT by RNA sequencing, measured its expression pattern by quantitative real-time PCR and Western blot. PGT was found to be upregulated in preeclamptic placental tissue. The expression pattern of PGT in PE was double confirmed by eight Gene Expression Omnibus (GEO) databases. In abortion tissues at 6-8 weeks, we then observed the cellular location of PGT by Immunofluorescence technique (IF) and found PGT located in trophoblast cell of the placenta of early pregnancy. In vitro studies revealed that forced expression of PGT in HTR8/Sveno cell inhibited its apoptosis, but promoted its proliferation by activating Erk signaling. In vivo study, we used reduced uterine perfusion pressure (RUPP) rat model and L-NAME-induced preeclampsia-like rats to study the possible role of PGT in preeclampsia. And PGT was found to be upregulated in both preeclampsia rat models by Immunohistochemical (IHC) staining. Newly identified PGT plays an important role in trophoblast proliferation via Erk signaling, providing new insights for understanding the pathogenesis of PE.

Abstract
Objective: This study aimed to quantitatively assess myocardial strain in preterm children aged 5 to 8 years of pregnancy complicated by severe preeclampsia (PE) by two-dimensional (2D) speckle tracking echocardiography. Method: A cohort study of 23 preterm children delivered by severe PE pregnant women from 2010 to 2012 in the First Affiliated Hospital of Soochow University was carried out. 23 preterm children from uneventful pregnancies in the same period served as controls. Myocardial functions including left ventricular longitudinal strain, radial strain, circumferential strain, and right ventricular longitudinal strain were evaluated by conventional Doppler, tissue Doppler imaging, and 2D speckle-tracking echocardiography (2D STE). All examinations were performed by an experienced ultrasonographer using the VIVID E9 (GE Healthcare) machine, according to standard techniques. Results: Children aged 5–8 years delivered from severe PE presented less weight (24.41 vs. 20.89 kg, P < 0.05), shorter height (124.1 vs 115.6 cm, P < 0.05) and faster heart rates (84 vs. 93 bpm, P < 0.05) compared to offspring of normotensive women. There were no significant differences in global left ventricular longitudinal strain, radial strain, circumferential strain, and right ventricular longitudinal strain between the children in the experimental group and the control group (P > 0.05). Conclusion: Exposure to the intrauterine environment of severe PE during the fetal period did not have a significant impact on cardiac structure in premature children at 5–8 years old, but they had a higher resting heart rate which may be associated with cardiovascular disease in the long run.

Abstract
Endothelial dysfunction, impaired implantation and placental insufficiency have been identified as mechanisms behind the development of pre-eclampsia, resulting in angiogenic factors' alteration. Angiogenic imbalance is also associated with congenital heart defects, and this common physiologic pathway may explain the association between them and pre-eclampsia. This review aims to understand the physiology shared by these two entities and whether women with pre-eclampsia have an increased risk of fetal congenital heart defects (or the opposite). The present research has highlighted multiple vasculogenic pathways associated with heart defects and preeclampsia, but also epigenetic and environmental factors, contributing both. It is also known that fetuses with a prenatal diagnosis of congenital heart disease have an increased risk of several comorbidities, including intrauterine growth restriction. Moreover, the impact of pre-eclampsia goes beyond pregnancy as it increases the risk for following pregnancies and for diseases later in life in both offspring and mothers. Given the morbidity and mortality associated with these conditions, it is of foremost importance to understand how they are related and its causative mechanisms. This knowledge may allow earlier diagnosis, an adequate surveillance or even the implementation of preventive strategies.

Abstract
Preeclampsia (PE) is a common obstetric disease and a major cause of maternal, newborn, and fetal death. This condition is a multisystem disorder characterized by hypertension, proteinuria, and involvement of the kidney, liver, and nervous system. It is generally believed that the placenta is the main cause of PE. circRNAs are a special class of noncoding RNAs that can form covalently closed continuous ring structures with tissue-specific conservation, and they have been reported to play a wide range of regulatory functions in various diseases, including PE. In this study, we reported a novel circUBAP2 (hsa_circ_0003496) and found that it was downregulated in placental tissues from patients with PE compared to healthy controls. After knocking down circUBAP2 in trophoblast cells, we found that cell proliferation and migration were significantly suppressed. In addition, preliminary mechanistic studies showed that circUBAP2 can sponge miR-1244, and FOXM1 was identified as a target gene for miR-1244. Cotransfection of si-circUBAP2 and a miR-1244 inhibitor partially reversed the suppressive effect induced by circUBAP2 depletion on proliferation and migration. In conclusion, the circUBAP2/miR-1244/FOXM1 axis might be a promising molecular marker for the diagnosis and treatment of PE.

Preeclampsia in Different Maternal Age Groups-Is There an Association with Pregnancy Outcomes and Placental Pathology? Reprod Sci 2020; 27:1879-1887.

Abstract
We aimed to compare maternal characteristics, pregnancy outcomes, and placental pathology in pregnancies complicated by preeclampsia at three different maternal age groups. Medical records and pathological reports of patients diagnosed with preeclampsia and delivered between 2008 and 2018 in a single tertiary center, were reviewed. Preeclampsia was diagnosed according to the current ACOG guidelines. Study population was divided into 3 groups of maternal age: group 1-< 27 years; group 2-27-35 years; and group 3-> 35 years (advanced maternal age = AMA). Data regarding maternal characteristics, neonatal outcomes, and placental histopathological lesions were compared between the groups. Composite adverse neonatal outcome was defined as ≥ 1 early neonatal complication. The AMA group (n = 145) was associated with a higher BMI, and higher rates of diabetes mellitus (DM), chronic hypertension (CHTN), and Cesarean deliveries compared with group 1 (n = 107) and group 2 (n = 255). The AMA group also had lower neonatal birthweights and a higher rate of composite adverse neonatal outcome compared with the other age groups. None of the placental lesions differed between the groups. By multivariable analysis, we found that maternal age (aOR 1.36, 95% CI 1.17-3.93), GA at delivery (aOR 0.80, 95% CI 0.61-0.90), DM (aOR 1.19, 95% CI 1.07-3.05), and CHTN (aOR 1.23, 95% CI 1.08-2.01) were independently associated with composite adverse neonatal outcome. Pregnancies at AMA were associated with higher complication rates, but without any differences in placental pathology, suggesting that the worse outcomes associated with AMA in preeclampsia are attributed to maternal chronic morbidities and not to differences observed in placental pathology.

Incomplete maternal vascular responses to pregnancy contribute to pregnancy complications including intrauterine growth restriction (IUGR) and preeclampsia. We aimed to characterize maternal vascular dysfunction in a murine model of fetal growth restriction as an approach toward identifying targetable pathways for improving pregnancy outcomes. We utilized a murine model of late-gestation hypoxia-induced IUGR that reduced E18.5 fetal weight by 34%. Contrary to our hypothesis, uterine artery blood flow as measured in vivo by Doppler ultrasound was increased in mice housed under hypobaric hypoxia (385 mmHg; 5500 m) vs normoxia (760 mmHg; 0 m). Using wire myography, uterine arteries isolated from hypoxic mice had similar vasodilator responses to the two activators A769662 and acetylcholine as those from normoxic mice, although the contribution of an increase in nitric oxide production to uterine artery vasodilation was reduced in the hypoxic vs normoxic groups. Vasoconstrictor responses to phenylephrine and potassium chloride were unaltered by hypoxia. The levels of activated adenosine monophosphate-activated protein kinase (AMPK) were reduced with hypoxia in both the uterine artery and placenta as measured by western blot and immunohistochemistry. We concluded that the rise in uterine artery blood flow may be compensatory to hypoxia but was not sufficient to prevent fetal growth restriction. Although AMPK signaling was reduced by hypoxia, AMPK was still receptive to pharmacologic activation in the uterine arteries in which it was a potent vasodilator. Thus, AMPK activation may represent a new therapy for pregnancy complications involving reduced uteroplacental perfusion.

Shared Molecular Features Linking Endometriosis and Obstetric Complications. Reprod Sci 2020; 27:1089-1096.

Abstract
Recent epidemiological research has shown the increased risk of adverse pregnancy outcomes in women with endometriosis compared with the general population. The aim of this review is to explore common pathophysiologic mechanisms between endometriosis and obstetric complications. A computerized literature search was performed to identify relevant studies. The search covered the period between January 2008 and October 2018. One of the potential mechanisms driving the initiation and progression of endometriosis is the accumulation of a variety of epigenetic changes in endometrial cells. Epigenetic control of gene expression which is considered to be responsible for the development of endometriosis is commonly seen in patients with preeclampsia, small for gestational age (SGA), or preterm birth. DLX5 and GATA3, paternally imprinted genes, and CDKN1C, a maternally imprinted gene, were aberrantly expressed in placenta tissues of the preeclampsia; CDKN1C, the growth inhibitor gene, was upregulated in human SGA placentas; and hypomethylation of PTGER2 would be associated with preterm birth. Preeclampsia, SGA, or preterm birth may share common epigenetic alterations with endometriosis, which raises the possibility that the occurrence of two conditions might be nonrandom. To date, however, there is a lack of evidence that links endometriosis and other obstetric complications, such as postpartum hemorrhage or placental abruption, at the epigenetic level. In conclusion, epigenetic changes may be a common hallmark of two conditions: endometriosis and obstetrical complications, such as preeclampsia, SGA, or preterm birth.

Effect of pregravid obesity on perinatal outcomes in singleton pregnancies following in vitro fertilization and the weight-loss goals to reduce the risks of poor pregnancy outcomes: A retrospective cohort study. PLoS One 2020; 15:e0227766. [PMID: 32053669 PMCID: PMC7027660 DOI: 10.1371/journal.pone.0227766] [Citation(s) in RCA: 9] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/25/2019] [Accepted: 12/27/2019] [Indexed: 11/25/2022] Open
Abstract
OBJECTIVE In the present study, we aimed to determine whether pregravid obesity independently predicts increased risks of perinatal complications following in vitro fertilization (IVF) and the weight loss goals to reduce the risk of poor pregnancy outcomes. DESIGN Retrospective cohort study. POPULATION All pregnancies after first the fresh IVF cycle from January 2014 to December 2016 in the Reproductive Center affiliated to Shandong University were reviewed. A total of 3,962 eligible singleton births were stratified into cohorts based on the body mass index (BMI) definitions of the Working Group on Obesity in China (WGOC). MAIN OUTCOME MEASURES Adverse perinatal outcomes. RESULTS Pregravid overweight and obesity were associated with increased risks of gestational diabetes mellitus (GDM), hypertensive disorders of pregnancy (HDP), including gestational hypertension (GH) and pre-eclampsia (PE), polyhydramnios, preterm premature rupture of the membranes (PPROM), placental abruption, preterm birth (PTB) <37 weeks, caesarean section (CS), fetal macrosomia, large for gestational age (LGA) >90th percentile, neonatal respiratory distress syndrome (NRDS), neonatal intensive care unit (NICU) admission and congenital anomalies as compared with the normal-weight group after adjustment of differences in age, parity, polycystic ovary syndrome (PCOS) and type of controlled ovarian hyperstimulation (COH). The increased risks of PPROM, NRDS and congenital anomalies were eliminated after adjustment of GDM development, whereas the increased risk of NRDS disappeared after adjustment of HDP. Placenta previa was not significantly different between the obese group and reference group (REF). Moreover, the rates of postpartum hemorrhage (PPH), PTB<32 weeks, small for gestational age (SGA) >90th percentile and perinatal mortality were also not significantly different between above-mentioned two groups. For obese women, a 10%-15% reduction in prepregnancy BMI was associated with significantly decreased risks of GH, CS and fetal macrosomia. For overweight women, just a 5% reduction in BMI could significantly reduce the risks of GDM, CS and fetal macrosomia. CONCLUSIONS Pregravid obesity could independently predict a higher risk of adverse pregnancy outcomes after adjustment of differences in maternal age, parity, PCOS, and type of COH in IVF pregnancies. The potential mechanism that obesity potentiated the risks of some poor perinantal outcomes might occur through the development of GDM and HDP. A 10%-15% reduction in pregravid BMI for obese women and a 5% reduction for overweight women were associated with a significant reduction of poor perinatal complications.

Abstract
CONTEXT Polycystic ovary syndrome (PCOS) is the most common endocrinopathy of reproductive-aged women. In pregnancy, women with PCOS experience increased risk of miscarriage, gestational diabetes, preeclampsia, and extremes of fetal birth weight, and their offspring are predisposed to reproductive and cardiometabolic dysfunction in adulthood. Pregnancy complications, adverse fetal outcomes, and developmental programming of long-term health risks are known to have placental origins. These findings highlight the plausibility of placental compromise in pregnancies of women with PCOS. EVIDENCE SYNTHESIS A comprehensive PubMed search was performed using terms "polycystic ovary syndrome," "placenta," "developmental programming," "hyperandrogenism," "androgen excess," "insulin resistance," "hyperinsulinemia," "pregnancy," and "pregnancy complications" in both human and animal experimental models. CONCLUSIONS There is limited human placental research specific to pregnancy of women with PCOS. Gestational androgen excess and insulin resistance are two clinical hallmarks of PCOS that may contribute to placental dysfunction and underlie the higher rates of maternal-fetal complications observed in pregnancies of women with PCOS. Additional research is needed to prevent adverse maternal and developmental outcomes in women with PCOS and their offspring.

Abstract
Background Oxidative stress is involved in the pathogenesis and maintenance of pregnancy-related disorders, such as intrauterine growth restriction (IUGR) and preeclampsia (PE). Human umbilical cord mesenchymal stem cells (hUMSCs) have been suggested as a possible therapeutic tool for the treatment of pregnancy-related disorders in view of their paracrine actions on trophoblast cells. Objectives To quantify the plasma markers of peroxidation in patients affected by PE and IUGR and to examine the role of oxidative stress in the pathophysiology of PE and IUGR in vitro by using hUMSCs from physiological and pathological pregnancies and a trophoblast cell line (HTR-8/SVneo). Study design In pathological and physiological pregnancies the plasma markers of oxidative stress, arterial blood pressure, serum uric acid, 24h proteinuria, weight gain and body mass index (BMI) were examined. Furthermore, the pulsatility index (PI) of uterine and umbilical arteries, and of fetal middle cerebral artery was measured. In vitro, the different responses of hUMSCs, taken from physiological and pathological pregnancies, and of HTR-8/SVneo to pregnancy-related hormones in terms of viability and nitric oxide (NO) release were investigated. In some experiments, the above measurements were performed on co-cultures between HTR-8/SVneo and hUMSCs. Results The results obtained have shown that in pathological pregnancies, body mass index, serum acid uric, pulsatility index in uterine and umbilical arteries and markers of oxidative stress were higher than those found in physiological ones. Moreover, in PE and IUGR, a relation was observed between laboratory and clinical findings and the increased levels of oxidative stress. HTR-8/SVneo and hUMSCs showed reduced viability and increased NO production when stressed with H2O2. Finally, HTR-8/SVneo cultured in cross-talk with hUMSCs from pathological pregnancies showed a deterioration of cell viability and NO release when treated with pregnancy-related hormones. Conclusion Our findings support that hUMSCs taken from patients affected by PE and IUGR have significant features in comparison with those from physiologic pregnancies. Moreover, the cross-talk between hUMSCs and trophoblast cells might be involved in the etiopathology of IUGR and PE secondary to oxidative stress.

Abstract
Preeclampsia is a complex genetic disorder and its pathogenesis remains to be investigated. Single nucleotide polymorphisms serve important roles in genetic predisposition. The present study aimed to explore the association between runt-related transcription factor 3 (RUNX3) gene polymorphisms in severe preeclampsia (SPE) and clinical features.A total of 417 participants were enrolled in the present study. The rs2236852, rs7528484 and rs760805 polymorphisms of the RUNX3 gene were tested using the polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) method. Clinical information of patients and controls was collected. Relationship between clinical feature and different genotype was analyzed.Compared with rs2236852 GG genotype carriers, the odds ratios (OR) for the risk of SPE were 2.26 [95% confidence interval (CI), 1.24-4.12; P = .023] in AA genotype carriers. A significantly increased risk of SPE was associated with AG/AA genotypes compared with GG genotypes (OR, 1.74; 95% CI, 1.11-2.75; P = .015). AA homozygote carriers with SPE exhibited lower birth weight, shorter birth length and reduced incidence of hypoproteinemia compared with AG heterozygote carriers (P <.05). A significantly increased risk of SPE was determined to be associated with the rs7528484 CC genotype in codominant and recessive models (CC vs TT: OR, 3.70, 95% CI, 1.31-10.43, P = .01; CC vs TT/TC: OR, 3.98, 95% CI, 1.46-10.87, P = .003). Patients carrying C-allele (TC + CC) presented increased systolic pressure and an increased incidence of neonatal pneumonia compared with TT homozygote carriers (P <.05). Compared with rs760805 TT homozygote carriers, patients carrying AA homozygote exhibited significantly reduced 24 hours urinary protein levels, lower serum creatinine concentrations and a decreased incidence of neonatal asphyxia (P <.05).The present study suggested a genetic association between RUNX3 gene polymorphisms and SPE. The data provided a novel insight to guide future investigations.

Abstract
Preeclampsia (PE) is a common obstetrical disorder characterized by hypertension and proteinuria. The aberrant expression of miR-221-3p in placental tissues has been implicated in the pathogenesis of PE. This study examined the role of miR-221-3p in trophoblast growth, invasion and migration, and explored the underlying mechanisms. Our results showed that miR-221-3p was down-regulated in placental tissues from PE patients compared to heathy controls as measured by quantitative real-time PCR assay. CCK-8 assay, Transwell invasion assay and wound healing assay showed that miR-221-3p overexpression promoted trophoblast (HTR-8/SVneo cells) growth, invasion and migration, and knockdown of miR-221-3p exerted the opposite effects. Flow cytometry experiments further demonstrated that miR-221-3p overexpression inhibited apoptosis, increased cell population at S phase, and decreased cell population at G0/G1 phase of HTR-8/SVneo cells; while miR-221-3p knockdown exerted the opposite effects. Bioinformatics prediction and luciferase reporter assay showed that miR-221-3p targeted the 3' untranslated region of thrombospondin 2 (THBS2), and qRT-PCR and western blot assays revealed that miR-221-3p negatively regulated the expression of THBS2 in HTR-8/SVneo cells. Furthermore, overexpression of THBS2 attenuated the in vitro effects of miR-221-3p overexpression on cell growth, invasion and migration of HTR-8/SVneo cells. The clinical sample analysis showed that the mRNA expression levels of THBS2 was significantly increased in placental tissues from PE patients and was negatively correlated with expression levels of miR-221-3p. In summary, our results demonstrated that miR-221-3p was down-regulated in PE, and the in vitro functional assays revealed that miR-221-3p promoted trophoblast growth, invasion and migration partly via targeting THBS2.

Abstract
Metabolic-related diseases are attributed to a sedentary lifestyle and eating habits, and there is now an increased awareness regarding pregnancy as a preponderant window in the programming of adulthood health and disease. The developing foetus is susceptible to the maternal environment; hence, any unfavourable condition will result in foetal physiological adaptations that could have a permanent impact on its health. Some of these alterations are maintained via epigenetic modifications capable of modifying gene expression in metabolism-related genes. Children born to mothers with dyslipidaemia, pregestational or gestational obesity, and gestational diabetes mellitus, have a predisposition to develop metabolic alterations during adulthood. CpG methylation-associated alterations to the expression of several genes in the human placenta play a crucial role in the mother-to-foetus transfer of nutrients and macromolecules. Identification of epigenetic modifications in metabolism-related tissues of offspring from metabolic-altered pregnancies is essential to obtain insights into foetal programming controlling newborn, childhood, and adult metabolism. This review points out the importance of the foetal milieu in the programming and development of human disease and provides evidence of this being the underlying mechanism for the development of adulthood metabolic disorders in maternal dyslipidaemia, pregestational or gestational obesity, and gestational diabetes mellitus.
