Abstract
Fetal growth restriction (FGR) in human pregnancy is associated with perinatal mortality, short- and long-term morbidities. No prenatal therapy is currently established despite decades of research. We aimed to review interventions in animal models for prenatal FGR treatment, and to seek the next steps for an effective clinical therapy. We registered our protocol and searched MEDLINE, Embase, and The Cochrane Library with no language restrictions, in accordance with the PRISMA guideline. We included all studies that reported the effects of any prenatal intervention in animal models of induced FGR. From 3257 screened studies, 202 describing 237 interventions were included for the final synthesis. Mice and rats were the most used animals (79%) followed by sheep (16%). Antioxidants (23%), followed by vasodilators (18%), nutrients (14%), and immunomodulators (12%) were the most tested therapy. Two-thirds of studies only reported delivery or immediate neonatal outcomes. Adverse effects were rarely reported (11%). Most studies (73%), independent of the intervention, showed a benefit in fetal survival or birthweight. The risk of bias was high, mostly due to the lack of randomization, allocation concealment, and blinding. Future research should aim to describe both short- and long-term outcomes across various organ systems in well-characterized models. Further efforts must be made to reduce selection, performance, and detection bias.

Copper exposure disrupts ovarian steroidogenesis in human ovarian granulosa cells via the FSHR/CYP19A1 pathway and alters methylation patterns on the SF-1 gene promoter. Toxicol Lett 2021; 356:11-20. [PMID: 34871762 DOI: 10.1016/j.toxlet.2021.12.002] [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: 10/08/2021] [Revised: 11/29/2021] [Accepted: 12/02/2021] [Indexed: 12/31/2022]
Abstract
Information on the effects of copper on reproduction is limited. Our previous study indicated that copper induces abnormal steroidogenesis in human ovarian granulosa cells, but the underlying mechanism remains unclear. In this study, human ovarian granulosa cells were treated with multiple concentrations of copper for 24 h. After treatment, the 17-estradiol levels were significantly increased (29.83 % and 45.12 %, respectively) in the 1.0 and 2.0 μg/mL groups but decreased (23.06 % and 31.56 %, respectively) in the 20.0 and 40.0 μg/mL groups (P < 0.05). Similar changes in the levels of FSHR, StAR, CYP11A1, CYP19A1, HSD3β1, and SF-1 were observed. The protein levels of FSHR were increased in the 2.0 μg/mL group but decreased in the 20.0 and 40.0 μg/mL groups (P < 0.05). Moreover, copper partially reversed the FSH-induced increase in FSHR, CYP19A1 and 17-estradiol levels, and the decreased effect of the FSH receptor binding inhibitor fragment on FSHR, CYP19A1, and 17-estradiol became more apparent after adding copper. Additionally, the total methylation levels of the SF-1 promoter and DNMTs expression were significantly decreased following copper treatment. Overall, our results indicate that copper exposure induces steroidogenesis disorders via the FSHR/CYP19A1 pathway and changes DNA methylation on the SF-1 promoter in human ovarian granulosa cells.

Abstract
Recurrent spontaneous abortion (RSA) is usually defined as three or more spontaneous abortions prior to 20-28 weeks gestation. RSA affects approximately 2-5% of all women of childbearing age, and it brings tremendous psychological and psychiatric trauma to the women and also results in economic burden. The causes could be female age, anatomical and chromosomal abnormalities, genetic, endocrinological, placental anomalies, infection, smoking and alcohol consumption, psychological factor, exposure to environmental factors such as heavy metal, environment pollution, and radiation.

Abstract
Copper is an essential trace nutrient and an enzymatic cofactor necessary for diverse physiological and biological processes. Copper metabolism is uniquely controlled in the placenta and changes to copper metabolism have been linked with adverse birth outcomes. We investigated associations between patterns of DNA methylation (DNAm; measured at >485 k CpG sites) and copper concentration measured from placentae in two independent mother-infant cohorts: the New Hampshire Birth Cohort Study (NHBCS, n = 306) and the Rhode Island Child Health Study (RICHS, n = 141). We identified nine copper-associated differentially methylated regions (DMRs; adjusted P < 0.05) and 15 suggestive CpGs (raw P < 1e-5). One of the most robust variably methylated CpGs associated with the expression of the antioxidant, GSTP1. Our most robust DMR negatively associates with the expression of the zinc-finger gene, ZNF197 (FDR = 4.5e-11). Genes co-expressed with ZNF197, a transcription factor, are enriched for genes that associate with birth weight in RICHS (OR = 2.9, P = 2.6e-6, N = 194), genes that are near a ZNF197 consensus binding motif (OR = 1.34, P = 0.01, N = 194), and for those classified in GO biological processes growth hormone secretion (P = 3.4e-4), multicellular organism growth (P = 3.8e-4), and molecular functions related to lipid biosynthesis (P = 1.9e-4). Further, putative transcriptional targets for ZNF197 include genes involved in copper metabolism and placentation. Our results suggest that copper metabolism is tied to DNAm in the placenta and that copper-associated patterns in DNAm may mediate normal placentation and foetal development.

Abstract
Organic compounds have been linked to adverse pregnancy complications. Perfluorooctanesulfonic acid (PFOS), a man-made fluorosurfactant and global pollutant, has been shown to induce oxidative stress in various cell types. Oxidative stress plays a key role in leading several placental diseases including preeclampsia (PE), gestational diabetes, spontaneous abortion, preterm labor, and intrauterine growth restriction. Recently, epigenetic regulation such as histone modifications, DNA methylation, and microRNAs (miRNAs), are shown to be associated with oxidative stress as well as pregnancy complications such as PE. However, whether PFOS exerts its detrimental effects in the placenta through epigenetics remains to be unveiled. Therefore, we aimed to investigate the effect of PFOS-induced reactive oxygen species (ROS) generation in first trimester human trophoblast cell line (HTR-8/SVneo) and whether epigenetic regulation is involved in this process. When treated with a range of PFOS doses at 24 and 48 h, even at 10 μM, it significantly increased the ROS production and decreased gene and protein expression, respectively, of the DNA methyltransferases DNMT1 (p < 0.001; p < 0.05), DNMT3A (p < 0.001; p < 0.05), and DNMT3B (p < 0.01; p < 0.01) and the sirtuins, for example, SIRT1 (p < 0.001; p < 0.001) and SIRT3 (p < 0.001; p < 0.05), while reducing global DNA methylation (p < 0.01) and increasing protein lysine acetylation (p < 0.001) as compared to vehicle controls. Interestingly, PFOS (10 μM) significantly increased miR29-b (p < 0.01), which has been previously reported to be associated with PE. The observed epigenetic effects were shown to be dependent on the expression of miR-29b, as knockdown of miR-29b significantly alters the gene and protein expression of DNMT1, DNMT3A, DNMT3B, SIRT1, and SIRT3 and ROS production as well as global DNA methylation and protein acetylation. This study provides for the first time a novel insight into PFOS-induced ROS generation via regulation of sets of the interactive epigenetic circuit in the placenta, which may lead to pregnancy complications.

Abstract
BACKGROUND Hyperglycemia-related oxidative stress and hypoxia are important mechanisms responsible for diabetes-induced embryopathy and other complications. High sucrose low copper diet (HSD), but not regular diet (RD), induces type 2 diabetes in the inbred Cohen diabetic sensitive (CDs) rats but not in the Sabra control rats. We recently demonstrated long-term changes of DNA methylation and gene expression in various groups of genes, including genes involved in oxidant-antioxidant activity in the liver of 2-4-week-old CDs offspring of diabetic dams. We now studied the postnatal effects of diabetes and/or HSD on several liver metabolic parameters in these offspring. METHODS we studied lipid peroxidation, activity of the antioxidants enzymes superoxide dismutase (SOD) and Catalase (CAT). By immunohistochemistry: protein oxidation by nitrotyrosine staining, hypoxia inducing factor1α (HIF1α), apoptosis [caspase 3, bcl-2-like protein (BAX)], proliferation [proliferating cell nuclear antigen (PCNA)] and NF-κB. RESULTS In the Sabra rats fed HSD only few, early and transitional changes were observed in lipid peroxidation, SOD and CAT activity. In the CDs fed HSD more significant changes in lipid and protein oxidation, HIF1α, apoptosis and proliferation were observed, persisting for longer. CONCLUSIONS The changes in the Sabra rats HSD were attributed to the pro-oxidant effects of the diet and those in the diabetic CDs to the HSD and maternal diabetes. In light of the DNA methylation changes in the liver of the CDs HSD, we presume that changes in gene expression are responsible for our findings, and that similar changes may lead to the metabolic syndrome at adulthood.

Abstract
INTRODUCTION Pregestational and gestational diabetes mellitus (PGDM; GDM) are significant health concerns because they are associated with an increased rate of malformations and maternal health complications. METHODS We reviewed the data that help us to understand the effects of diabetes in pregnancy. RESULTS Diabetic embryopathy can affect any developing organ system, but cardiovascular and neural tube defects are among the most frequent anomalies. Other complications include preeclampsia, preterm delivery, fetal growth abnormalities, and perinatal mortality. Neurodevelopmental studies on offspring of mothers with diabetes demonstrated increased rate of Gross and Fine motor abnormalities, of Attention Deficit Hyperactivity Disorder, learning difficulties, and possibly also Autism Spectrum Disorder. The mechanisms underlying the effects of maternal hyperglycemia on the developing fetus may involve increased oxidative stress, hypoxia, apoptosis, and epigenetic changes. Evidence for epigenetic changes are the following: not all progeny are affected and not to the same extent; maternal diet may influence pregnancy outcomes; and maternal diabetes alters embryonic transcriptional profiles and increases the variation between transcriptomic profiles as a result of altered gene regulation. Research in animal models has revealed that maternal hyperglycemia is a teratogen, and has helped uncover potential therapeutic targets which, when blocked, can mitigate or ameliorate the negative effects of diabetes on the developing fetus. CONCLUSIONS Tight metabolic control, surveillance, and labor management remain the cornerstone of care for pregnant women with diabetes, but advances in the field indicate that new treatments to protect the mother and baby are not far from becoming clinical realities.
