Abstract
The placenta plays a key role in several adverse obstetrical outcomes, such as preeclampsia, intrauterine growth restriction and gestational diabetes mellitus. The early identification of at-risk pregnancies could significantly improve the management, therapy and prognosis of these pregnancies, especially if these at-risk pregnancies are identified in the first trimester. The aim of this review was to summarize the possible biomarkers that can be used to diagnose early placental dysfunction and, consequently, at-risk pregnancies. We divided the biomarkers into proteins and non-proteins. Among the protein biomarkers, some are already used in clinical practice, such as the sFLT1/PLGF ratio or PAPP-A; others are not yet validated, such as HTRA1, Gal-3 and CD93. In the literature, many studies analyzed the role of several protein biomarkers, but their results are contrasting. On the other hand, some non-protein biomarkers, such as miR-125b, miR-518b and miR-628-3p, seem to be linked to an increased risk of complicated pregnancy. Thus, a first trimester heterogeneous biomarkers panel containing protein and non-protein biomarkers may be more appropriate to identify and discriminate several complications that can affect pregnancies.

Thapa R, Marmo K, Ma L, Torry DS, Bany BM. The Long Non-Coding RNA Gene AC027288.3 Plays a Role in Human Endometrial Stromal Fibroblast Decidualization. Cells 2024; 13:778. [PMID: 38727314 PMCID: PMC11083667 DOI: 10.3390/cells13090778] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/01/2024] [Revised: 04/26/2024] [Accepted: 04/26/2024] [Indexed: 05/13/2024] Open
Abstract
During the secretory phase of the menstrual cycle, endometrial fibroblast cells begin to change into large epithelial-like cells called decidual cells in a process called decidualization. This differentiation continues more broadly in the endometrium and forms the decidual tissue during early pregnancy. The cells undergoing decidualization as well as the resulting decidual cells, support successful implantation and placentation during early pregnancy. This study was carried out to identify new potentially important long non-coding RNA (lncRNA) genes that may play a role in human endometrial stromal fibroblast cells (hESF) undergoing decidualization in vitro, and several were found. The expression of nine was further characterized. One of these, AC027288.3, showed a dramatic increase in the expression of hESF cells undergoing decidualization. When AC027288.3 expression was targeted, the ability of the cells to undergo decidualization as determined by the expression of decidualization marker protein-coding genes was significantly altered. The most affected markers of decidualization whose expression was significantly reduced were FOXO1, FZD4, and INHBA. Therefore, AC027288.3 may be a major upstream regulator of the WNT-FOXO1 pathway and activin-SMAD3 pathways previously shown as critical for hESF decidualization. Finally, we explored possible regulators of AC027288.3 expression during human ESF decidualization. Expression was regulated by cAMP and progesterone. Our results suggest that AC027288.3 plays a role in hESF decidualization and identifies several other lncRNA genes that may also play a role.

Abstract
Non-coding RNAs (ncRNAs) are transcribed from the genome and do not encode proteins. In recent years, ncRNAs have attracted increasing attention as critical participants in gene regulation and disease pathogenesis. Different categories of ncRNAs, which mainly include microRNAs (miRNAs), long non-coding RNAs (lncRNAs), and circular RNAs (circRNAs), are involved in the progression of pregnancy, while abnormal expression of placental ncRNAs impacts the onset and development of adverse pregnancy outcomes (APOs). Therefore, we reviewed the current status of research on placental ncRNAs and APOs to further understand the regulatory mechanisms of placental ncRNAs, which provides a new perspective for treating and preventing related diseases.

Downregulation of LINC00221 promotes angiopoiesis in HUVEC and inhibits recruitment of macrophages by augmenting miR-542-3p in trophoblast cells. J Assist Reprod Genet 2022; 39:2381-2393. [PMID: 36069974 PMCID: PMC9596644 DOI: 10.1007/s10815-022-02593-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/17/2022] [Accepted: 08/08/2022] [Indexed: 11/24/2022] Open
Abstract
PURPOSE To investigate the effects of long intergenic non-protein coding RNA 221 (LINC00221) on preeclampsia (PE) and its mechanism. METHODS The expression of LINC00221 was detected in placental tissues from PE patients and normal pregnant women (non-PE). Next, the effects of LINC00221 silencing on trophoblast cells (HTR-8/SVneo and JEG-3) and co-cultured HUVECs or macrophages were evaluated. Afterwards, miR-542-3p was confirmed to bind to LINC00221 directly, and miR-542-3p mimics and inhibitors were transfected into trophoblast cells. Next, a rescue experiment was performed to examine the effect of LINC00221/miR-542-3p axis. Finally, the effect of LINC00221 was also verified in vivo in rat PE models. RESULTS The expression of LINC00221 was higher in placental tissues of PE patients than those of non-PE. LINC00221 silencing significantly reduced MCP1 level and increased the VEGF level in trophoblast cells. LINC00221 knockdown in trophoblast cells remarkably enhanced VEGFR expression and the angiopoiesis of HUVECs, and decreased the migration and invasion of macrophages and reduced TNF-α level. Besides, LINC00221 knockdown decreased CHOP, p-IREα, p-PERK, and iNOS expression and increased Trx expression. Notably, LINC00221 negatively regulated miR-542-3p expression. MiR-542-3p overexpression had an effect to that of LINC00221 knockdown, while miR-542-3p inhibition had the opposite effect. Treatment with miR-542-3p inhibitors partially reversed the protective effect of LINC00221 silencing. PE rat model results were consistent with those of in vitro experiments. CONCLUSIONS Downregulation of LINC00221 might reduce dysfunction, inflammatory responses, endoplasmic reticulum stress, and oxidative stress, and thereby protect against PE by augmenting miR-542-3p.

Abstract
Abstract
This study aimed to explore potential biomarkers and molecular mechanisms in preeclampsia (PE) progression. Gene expression profiles of GSE147776 and GSE96984 were downloaded, followed by the identification of common differentially expressed genes (co-DEGs) and common differentially expressed lncRNAs (co-DElncRNAs) in PE patients between the two datasets. Key genes were identified using gene set enrichment analysis (GSEA), followed by functional enrichment analyses. Subsequently, the miRNAs of key genes and miRNA-related lncRNAs were predicted, followed by the construction of the lncRNA–miRNA–gene ceRNA network. Furthermore, the key genes associated with different gestational stages were identified. As a result, 192 co-DEGs and 16 co-DElncRNAs were revealed from the two datasets. Based on two outstanding PE-associated pathways, including glaucoma and PE, identified by GSEA, ten key genes, including IGFBP1, CORIN, and C3, were revealed. Key genes, including IL1A and IL1B, were enriched in the developmental process involved in reproduction. Furthermore, ceRNAs, such as LINC00473-miR-4476-IL1A, LINC00473-miR-1291-IL1B, and NAV2-AS4-miR-6131-REN, were identified. Moreover, REN expression was significantly upregulated in the first- and second-trimester placentae compared to C-section-term placentae. In conclusion, these key genes may serve as novel biomarkers for PE. The detection of REN expression may help in the early prediction of PE and the initiation of prophylactic medical treatment.

Abstract
Non-coding RNAs (ncRNAs) play a central and regulatory role in almost all cells, organs, and species, which has been broadly recognized since the human ENCODE project and several other genome projects. Nevertheless, a small fraction of ncRNAs have been identified, and in the placenta they have been investigated very marginally. To date, most examples of ncRNAs which have been identified to be specific for fetal tissues, including placenta, are members of the group of microRNAs (miRNAs). Due to their quantity, it can be expected that the fairly larger group of other ncRNAs exerts far stronger effects than miRNAs. The syncytiotrophoblast of fetal origin forms the interface between fetus and mother, and releases permanently extracellular vesicles (EVs) into the maternal circulation which contain fetal proteins and RNA, including ncRNA, for communication with neighboring and distant maternal cells. Disorders of ncRNA in placental tissue, especially in trophoblast cells, and in EVs seem to be involved in pregnancy disorders, potentially as a cause or consequence. This review summarizes the current knowledge on placental ncRNA, their transport in EVs, and their involvement and pregnancy pathologies, as well as their potential for novel diagnostic tools.

Abstract
Abstract
Background
Preeclampsia (PE) is one of the complications of pregnancy. The pathogenesis of PE has not been completely understood. The aims of the present study were to investigate the role of Keap1 (rs11085735) variants and the methylation status of long non-coding RNA (lncRNA) MEG3 in the risk of PE.
Methods
In a case–control study, 150 pregnant women, including 75 PE patients and 75 healthy pregnant women recruited from Western Iran with Kurdish ethnic background, were studied for Keap1 variants using polymerase chain reaction‐restriction fragment length polymorphism (PCR-RFLP). The methylation status of lncRNA MEG3 was investigated using methylation-specific PCR (MSP) among 50 preeclamptic patients and 50 controls.
Results
The frequency of Keap1 A allele was significantly lower (5.3%) in preeclamptic patients compared to controls (12.7%, p = 0.024). The frequencies of hemimethylated (UM) and full methylated (MM) lncRNA MEG3 were 94 and 6% (p = 0.04), respectively, in all patients, 86.4, and 13.6% (p = 0.04), respectively, in patients with severe preeclampsia and 98 and 0% in controls. The frequency of full methylated lncRNA MEG3 was 14.3% in early-onset preeclampsia and 2.8% in late-onset preeclampsia (p = 0.12). Patients with PE had significantly higher levels of liver biomarkers (including ALT, AST, ALP, and total bilirubin) and lower PLT counts compared to healthy pregnant women.
Conclusion
The present study suggests the presence of hypermethylation status of lncRNA MEG3 in preeclampsia that might contribute to the pathogenesis and development of preeclampsia. Also, Keap1 rs11085735 polymorphism might be involved in the risk of preeclampsia.

Abstract
Preeclampsia (PE) is a pregnancy-related complication. Dysregulation of long non-coding RNAs (lncRNAs) contributes to the pathogenesis of PE. The current study sought to investigate the effect of lncRNA small nucleolar RNA host gene 5 (SNHG5) on trophoblast autophagy in PE. A PE mouse model was established, followed by detection of parameters such as blood pressure, proteinuria, triglycerides, total cholesterol, low-density lipoprotein, and high-density lipoprotein, observation of alterations of mouse placenta and kidney, and detection of B-cell chronic lymphocytic leukemia/lymphoma-2, Bcl-2-associated X protein, and SNHG5 expression patterns. The expressions of LC3, Beclin-1, and p62 in the placenta of PE mice were detected. Moreover, the SNHG5 expression was downregulated in the established HTR-8/SVneo trophoblast model, followed by evaluation of cell proliferation, apoptosis, and autophagy. After combination treatment with 3-MA (an autophagy inhibitor) and si-SNHG5, the behaviors of HTR-8/SVneo cells were observed. The binding relations between SNHG5 and miR-31-5p, and miR-31-5p and SPARC were verified. The expressions of miR-31-5p and SPARC in the placenta of mice and trophoblasts were determined. Our results demonstrated a poor expression of lncRNA SNHG5 in PE mice. SNHG5 overexpression reduced the PE phenotype and tissue damage in mice. SNHG5 silencing reduced the proliferation, migration, and invasion of trophoblasts, but elevated apoptosis and autophagy. SNHG5 sponged miR-31-5p to promote SPARC transcription. Additionally, miR-31-5p knockdown or 3-MA treatment reverted the stimulative effect of SNHG5 silencing on trophoblast autophagy. Collectively, our study demonstrated that lncRNA SNHG5 alleviated the PE phenotype and inhibited trophoblast autophagy by sponging miR-31-5p and promoting SPARC transcription.

Abstract
Perfluorooctane sulfonic acid (PFOS) is a persistent environmental pollutant. Exposure to PFOS has been associated with abnormal fetal development. The long non-coding RNA (lncRNA) has been showed to play a role in fetal growth restriction (FGR), preeclampsia (PE) and other pregnancy complications. Whether the lncRNA contributes to PFOS-induced toxicity in the placenta remains unknown. In this study, we investigated the function of lncRNA MEG3 and its derived miR-770 in PFOS-induced placental toxicity. Pregnant mice received gavage administration of different concentrations of PFOS (0.5, 2.5, and 12.5 mg/kg/day) from GD0 to GD17, and HTR-8/SVneo cells were treated with PFOS in the concentrations of 0, 10-1, 1, 10 μM. We found that expression levels of miR-770 and its host gene MEG3 were reduced in mice placentas and HTR-8/SVneo cells with exposure of PFOS. A significant hypermethylation was observed at MEG3 promoter in placentas of mice gestational-treated with PFOS. We also confirmed that MEG3 and miR-770 overexpression alleviated the cell growth inhibition induced by PFOS. Furthermore, PTX3 (Pentraxin 3) was identified as the direct target of miR-770 and it was enhanced after PFOS exposure. In summary, our results suggested that MEG3 alleviate PFOS-induced placental cell inhibition through MEG3/miR-770/PTX3 axis.

Abstract
BACKGROUND Preeclampsia (PE), one of hypertension-related disorders of pregnancy, is a common cause of maternal death worldwide. This study aimed to identify a circRNA-miRNA-mRNA-associated ceRNA network and related pathways in PE. MATERIAL AND METHODS We downloaded 3 microarray datasets from the Gene Expression Omnibus database, obtained 163 differentially expressed circRNAs (dif-circRNAs) (61 upregulated and 102 downregulated), 39 differentially expressed microRNAs (dif-miRNAs) (22 upregulated and 17 downregulated), and 271 differentially expressed mRNAs (dif-mRNAs) (168 upregulated and 103 downregulated) from placenta tissues of PE. Functional enrichment analysis and protein-protein interaction (PPI) network with module analysis of dif-mRNAs were performed. The regulatory relationship between dif-miRNAs and dif-mRNAs/circRNAs was predicted via related databases. A circRNA-miRNA-mRNA regulatory network was constructed. RESULTS A total of 53 pairs were obtained, including 13 circRNAs (10 upregulated and 3 downregulated), 9 miRNAs (3 upregulated and 6 downregulated) and 31 mRNAs (22 upregulated and 9 downregulated). GNB5 and IL2RB were obtained. KEGG enrichment analysis showed that both of them were closely related with the PI3K-Akt signalling pathway. Therefore, ceRNAs might affect the PI3K-Akt signalling pathway via the upregulation of GNB5 by binding to miR-1248 in PE. Meanwhile, hsa_circ_0052661 might upregulate IL2RB by binding miR-4303 to play a role in PE in the same way. CONCLUSION GNB5 and IL2RB might be key genes involved in the PI3K-Akt signalling pathway in PE, and hsa_circ_0087208, hsa_circ_0035443, hsa_circ_0067557 and hsa_circ_0052661 might regulate these key genes in PE by binding miR-1248 or miR-4303.Key messagesThere is still a lack of predictive and diagnostic factors for preeclampsia, which is a common cause of maternal death worldwide.This study identified a novel circRNA-associated ceRNA network and related pathways in preeclampsia.GNB5 and IL2RB might be key genes in their related circRNA-associated ceRNA network, and probably take an important role in preeclampsia via PI3K-Akt signalling pathway, which made them to be potential markers of preeclampsia.

EIF3D promotes the progression of preeclampsia by inhibiting of MAPK/ERK1/2 pathway. Reprod Toxicol 2021; 105:166-174. [PMID: 34520790 DOI: 10.1016/j.reprotox.2021.09.006] [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: 05/27/2021] [Revised: 08/19/2021] [Accepted: 09/09/2021] [Indexed: 12/21/2022]
Abstract
Preeclampsia (PE) has been recognized as one of the main reasons for neonatal and maternal mortality and morbidity. This study intended to identify certain genes that correlated with the pathogenesis of PE, and disclose the underlying mechanisms. The GSE14776 and GSE65271 datasets were obtained from the Gene Expression Omnibus database. Venn diagram analysis was performed to identify the differently expressed genes. The potential pathways were analyzed by Gene set enrichment analysis software. The expression of eukaryotic translation initiation factor 3 subunit D (EIF3D) in tissues and cells was respectively tested by immunohistochemistry and the quantitative real-time PCR. Cell transfection was utilized to alter the expression of EIF3D. Cell proliferation, invasion and migration were respectively tested by MTT, EdU, transwell and wound healing assays. Tube formation assay was utilized to determine the tube formation capacity of HTR-8/SVneo cells. ELISA was employed for determination of the concentration of Angiotensin (ANG)-1. Moreover, the expression of EIF3D, proliferation-, metastasis-, tube formation- and MAPK/ERK1/2 pathway-related proteins were measured utilizing western blot. EIF3D was selected in this study. EIF3D was upregulated in placentas tissues collected from patients with PE. EIF3D upregulation observably repressed the proliferation, invasion, migration, wound healing and tube formation of HTR-8/SVneo cells, and the expression of their associated proteins. Besides, the concentration of ANG-1, and the ratios of phosphorylated-ERK1/2 and phosphorylated-MEK1/MEK1 were also markedly lowered by EIF3D upregulation. Whereas, EIF3D knockdown exerted the opposite effects, and these effects were distinctly counteracted by ERK1/2 inhibitor SC-221593 treatment. In conclusion, these observations manifested that EIF3D upregulation might have repressed the progression of PE through modulation of MAPK/ERK1/2 pathway.

Abstract
Preeclampsia (PE) is a huge threat to pregnant women. Our previous study demonstrated that long non-coding RNA (lncRNA) NR_002794 was highly expressed in placentas of PE patients and could regulate the phenotypes of trophoblast cells. However, the downstream regulatory mechanisms of NR_002794 remain unknown. In this text, some potential downstream targets or signaling pathways of NR_002794 were identified through RNA sequencing (RNA-seq) and bioinformatics analysis in SWAN71 trophoblast cells. Western blot assay demonstrated that NR_002794 inactivated protein kinase B (AKT) and extracellular signal-regulated kinase 1/2 (ERK1/2) pathways and activated cell apoptotic signaling in SWAN71 cells. Both RNA-seq and reverse transcription-quantitative PCR (RT-qPCR) outcomes showed that NR_002794 up-regulation could notably inhibit the expression of C-C motif chemokine ligand 4 like 2 (CCL4L2), interleukin 15 receptor subunit alpha (IL15RA), interleukin 32 (IL32), and tyrosine kinase with immunoglobulin-like and EGF-like domains 1 (TIE1), while NR_002794 knockdown induced these gene expressions in SWAN71 cells. CCK-8, BrdU, Transwell, wound healing, and flow cytometry analyses showed that NR_002794 inhibited cell proliferation and migration and induced cell apoptosis through down-regulating TIE1 in SWAN71 cells. In conclusion, lncRNA NR_002794 could exert its functions by regulating AKT and ERK1/2 pathways and TIE1 expression in human trophoblast cells.

Abstract
BACKGROUND Preeclampsia (PE) is a pregnancy-specific disease that is associated with oxidative stress-induced endothelial dysfunction. Long noncoding RNAs (lncRNAs) are related to PE progression. The purpose is to study whether lncRNA taurine-upregulated gene 1 (TUG1) takes part in endothelial dysfunction in PE. METHODS The placenta tissues were collected from PE patients and normal subjects. Human umbilical vein endothelial cells (HUVECs) were suffered from hypoxia-reoxygenation (H/R). TUG1, miR-29a-3p and vascular endothelial growth factor A (VEGFA) were detected via qRT-PCR. soluble fms-related tyrosine kinase-1 (sFLT1) and soluble endoglin (sENG) levels were detected by ELISA. Cell proliferation, migration, invasion and angiogenesis were examined via MTT, wound healing analysis, transwell and tube formation analysis. The proteins in VEGFA and angiopoietin 2 (Ang2)/tyrosine kinase with immunoglobulin-like and EGF-like domains 2 (Tie2) signaling were measured by western blot. The binding relationship was analyzed via Starbase, Jefferson and dual-luciferase reporter analysis. RESULTS TUG1 and VEGFA levels were downregulated, and levels of miR-29a-3p, sFLT1 and sENG were increased in PE patients. TUG1 abundance was reduced in H/R-stimulated HUVECs, and TUG1 overexpression increased proliferation, migration, invasion and angiogenesis, and activated the VEGFA and Ang2/Tie2 signaling in H/R-stimulated HUVECs. TUG1 sponged miR-29a-3p, and miR-29a-3p overexpression reversed the function of TUG1 on H/R-induced HUVECs dysfunction. MiR-29a-3p knockdown attenuated H/R-induced inhibition of proliferation, migration, invasion, angiogenesis and activation of the VEGFA and Ang2/Tie2 signaling in HUVECs. VEGFA and Ang2 were targeted by miR-29a-3p, and VEGFA or Ang2 silence weakened the role of miR-29a-3p knockdown in H/R-caused HUVECs dysfunction. CONCLUSION TUG1 facilitates proliferation, migration, invasion and angiogenesis in H/R-stimulated HUVECs via activating the VEGFA and Ang2/Tie2 signaling by regulating miR-29a-3p.

Abstract
Long noncoding RNAs (lncRNAs) are crucial regulatory molecules involved in diverse biological processes and human diseases, including preeclampsia (PE). The lncRNA growth arrest associated lncRNA 1 (GASAL1) has been implicated in multiple malignant solid tumors and other diseases, while it is poorly known as the potential molecular mechanism of GASAL1 in PE. In this study, GASAL1 was significantly downregulated in the placentas' of tissues from primipara with PE and trophoblast cell lines. Then, the upregulation of GASAL1 dramatically decreased proliferation and invasion and enhanced apoptosis in HTR-8/SVneo and JAR cells. Bioinformatics tool predicated that there is a potential interaction between GASAL1 and serine/arginine splicing factor 1 (SRSF1). RNA pull-down assays showed that GASAL1 directly binds with SRSF1 that could promote cell proliferation and invasion and suppress cell apoptosis. Further research showed that promoting effects of trophoblasts proliferation and invasion caused by co-transfecting GASAL1 and SRSF1 into HTR-8/SVneo and JAR cells were impaired by SRSF1 knockdown. Moreover, inhibition of the mammalian target of rapamycin (mTOR) activity by rapamycin influenced the effects of GASAL1 on cell proliferation, invasion, and apoptosis. Taken together, these findings suggest that lncRNA GASAL1 interacts with SRSF1 to regulate the proliferative, invasive, and apoptotic abilities of trophoblast cells via the mTOR signaling pathway.

Abstract
Endothelial dysfunction is an early event in the pathogenesis of atherosclerosis and represents the first step in the pathogenesis of cardiovascular diseases. The evaluation of endothelial health is fundamental in clinical practice and several direct and indirect markers have been suggested so far to identify any alterations in endothelial homeostasis. Alongside the known endothelial role on vascular health, several pieces of evidence have demonstrated that proper endothelial functioning plays a key role in human fertility and reproduction. Therefore, this state-of-the-art review updates the endothelial health markers discriminating between those available for clinical practice or for research purposes and their application in human fertility. Moreover, new molecules potentially helpful to clarify the link between endothelial and reproductive health are evaluated herein.

MALAT1 sponges miR-26a and miR-26b to regulate endothelial cell angiogenesis via PFKFB3-driven glycolysis in early-onset preeclampsia. MOLECULAR THERAPY. NUCLEIC ACIDS 2021; 23:897-907. [PMID: 33614238 PMCID: PMC7868745 DOI: 10.1016/j.omtn.2021.01.005] [Citation(s) in RCA: 12] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 06/16/2020] [Accepted: 01/10/2021] [Indexed: 11/20/2022]
Abstract
6-phosphofructo-2-kinase (PFKFB3) is a crucial regulator of glycolysis that has been implicated in angiogenesis and the development of diverse diseases. However, the functional role and regulatory mechanism of PFKFB3 in early-onset preeclampsia (EOPE) remain to be elucidated. According to previous studies, noncoding RNAs play crucial roles in EOPE pathogenesis. The goal of this study was to investigate the functional roles and co-regulatory mechanisms of the metastasis-associated lung adenocarcinoma transcript-1 (MALAT1)/microRNA (miR)-26/PFKFB3 axis in EOPE. In our study, decreased MALAT1 and PFKFB3 expression in EOPE tissues correlates with endothelial cell (EC) dysfunction. The results of in vitro assays revealed that PFKFB3 regulates the proliferation, migration, and tube formation of ECs by modulating glycolysis. Furthermore, MALAT1 regulates PFKFB3 expression by sponging miR-26a/26b. Finally, MALAT1 knockout reduces EC angiogenesis by inhibiting PFKFB3-mediated glycolysis flux, which is ameliorated by PFKFB3 overexpression. In conclusion, decreased MALAT1 expression in EOPE tissues reduces the glycolysis of ECs in a PFKFB3-dependent manner by sponging miR-26a/26b and inhibits EC proliferation, migration, and tube formation, which may contribute to abnormal angiogenesis in EOPE. Thus, strategies targeting PFKFB3-driven glycolysis may be a promising approach for the treatment of EOPE.

Abstract
Gestational hypertension is a leading cause of both prenatal and maternal mortality and morbidity; however, there have been rather limited advances in the management of gestational hypertension in recent years. There has been evidence supporting the antihypertensive properties of crocin, but the specific mechanism is still unclear. N-Nitro-L-arginine methyl ester (L-NAME) was employed to establish a rat model with a preeclampsia-like phenotype, particularly gestational hypertension. Enzyme-linked immunosorbent assays were conducted to determine the levels of placental growth factor (PlGF) and soluble fms-like tyrosine kinase (sFlt-1); the levels of the circulating cytokines interleukin (IL)-1β, IL-6, and tumor necrosis factor (TNF)-α; and oxidative stress factors. Quantitative RT-PCR assays were performed to assess the transcript levels of various cytokines in the placenta, and western blot assays were carried out to evaluate the protein levels of heme oxygenase-1 (HO-1) and nuclear factor-erythroid 2-like 2 (Nrf-2). Treatment with crocin reduced the blood pressure of rats with gestational hypertension, which was accompanied by suppressed circulating levels of PlGF and sFlt-1. Crocin further alleviated the inflammatory signals and oxidative stress in the serum, as well as in placental tissues, in rats with L-NAME-induced hypertension. Crocin treatment also improved pregnancy outcomes in terms of fetal survival, fetal weight, and the fetal/placental weight ratio. Finally, in hypertension elicited by L-NAME, crocin stimulated the placental Nrf-2/HO-1 pathway. Crocin alleviated inflammatory and oxidative stress in placental tissues, thereby protecting against gestational hypertension, one of the major phenotypes of preeclampsia, and activated the Nrf-2/HO-1 pathway.

Abstract
The characteristics of fetal membrane cells and their phenotypic adaptations to support pregnancy or promote parturition are defined by global patterns of gene expression controlled by chromatin structure. Heritable epigenetic chromatin modifications that include DNA methylation and covalent histone modifications establish chromatin regions permissive or exclusive of regulatory interactions defining the cell-specific scope and potential of gene activity. Non-coding RNAs acting at the transcriptional and post-transcriptional levels complement the system by robustly stabilizing gene expression patterns and contributing to ordered phenotype transitions. Here we review currently available information about epigenetic gene regulation in the amnion and the chorion laeve. In addition, we provide an overview of epigenetic phenomena in the decidua, which is the maternal tissue fused to the chorion membrane forming the anatomical and functional unit called choriodecidua. The relationship of gene expression with DNA (CpG) methylation, histone acetylation and methylation, micro RNAs, long non-coding RNAs and chromatin accessibility is discussed in the context of normal pregnancy, parturition and pregnancy complications. Data generated using clinical samples and cell culture models strongly suggests that epigenetic events are associated with the phenotypic transitions of fetal membrane cells during the establishment, maintenance and termination of pregnancy potentially driving and consolidating the changes as pregnancy progresses. Disease conditions and environmental factors may produce epigenetic footprints that indicate exposures and mediate adverse pregnancy outcomes. Although knowledge is expanding rapidly, fetal membrane epigenetics is still in an early stage of development necessitating further research to realize its remarkable basic and translational potential.

Abstract
Spontaneous abortion (SA) is the spontaneous loss of a pregnancy before 20 gestational weeks. The causes of SA are still largely unknown. Long noncoding RNA (lncRNA) urothelial cancer associated 1 (UCA1) plays an important role in cellular progress. However, there is no report focusing on the role of UCA1 in SA. Here, we revealed that, compared with that in clinical samples from elective induced abortion, UCA1 expression was decreased in samples from SA patients as shown by qPCR method. The results demonstrated that UCA1 might be involved in the progress of SA. Then, we found that knockdown of UCA1 reduced cell viability and inhibited cell proliferation and migration of HTR-8/SVneo trophoblast cells as shown by CCK8, EdU, and Transwell methods. Furthermore, we demonstrated that UCA1 could act as a molecular sponge for miR-455 in HTR-8/SVneo cells as shown by luciferase reporter system method. In addition, miR-455 inhibited cell viability, cell proliferation and migration via regulating RUNX2 in HTR-8/SVneo cells. Ultimately, we illustrated that UCA1 plays its role via absorbing miR-455, thus promoting RUNX2 expression in HTR-8/SVneo cells. Collectively, this study first revealed the role and mechanism of UCA1 in the growth and migration of HTR-8/SVneo cells, indicating its potential as a diagnostic biomarker and therapeutic target for SA.

Background Preeclampsia (PE) is a widespread progressive condition that can occur pregnancy and is related to high maternal morbidity and fetal mortality in the perinatal period. However, the exact mechanism responsible has not been specific. Accumulating evidence has highlighted the prominent role of the epithelial‐mesenchymal transition (EMT) in the biological behaviors of PE. Methods We explored the role of a lincRNA in extravillous trophoblast (EVTs) cell viability, migration, invasion and apoptosis in vitro, along with the use of linc00468 knockdown or overexpression. Clinically, we discovered that the expression of linc00468 was frequently correlated with adverse clinical features and poor prognosis of PE patients. Results We uncovered that linc00468 was downregulated in PE samples compared to in healthy tissues and in trophoblast cells. Functionally, gain and loss-of-function experiments demonstrated that linc00468 inhibited cell proliferation, migration, invasion and linc00468 accelerated apoptosis of the trophoblast phenotype in cell lines. Moreover, we demonstrated that downregulation of linc00468 promoted the expression of E-cadherin and β-catenin but reduced the expression of N-cadherin, Vimentin and Snail, resulting in progression of EMT. Conclusions In conclusion, linc00468 promoted EMT and a consequent increase in invasiveness in HTR-8/Svneo and JAR EVT cell lines. Our study provides the first evidence that linc00468 has a pivotal role in cell invasion and promotes intrinsic and extrinsic EMT ability of PE.

Abstract
OBJECTIVE To investigate the expression profile of long non-coding RNAs (lncRNA) and identify potential lncRNA-related competing endogenous RNAs (ceRNA) in placenta accrete spectrum disorders (PAS). METHODS Five tissue specimens of placental implantation and 5 adjacent normal placental tissues were collected from cesarean section deliveries complicated by PAS in our hospital between December, 2017 and June, 2018. Human microarrays were used to identify the lncRNAs that were differentially expressed in PAS, and 5 of the identified lncRNAs were further validated using qRT-PCR. GO and KEGG pathway analyses were performed to indentify the most significant enrichment functions. A ceRNA network was constructed based on ENST00000511361 (RP5-875H18.4), NR_027457 (LINC00221) and NR_126415 (FOXP4-AS1) to pinpoint the potential lncRNAs-related ceRNA. RESULTS A total of 329 lncRNAs and 179 mRNAs were identified to have differential expression in PAS. The results of qRT-PCR were consistent with the human microarrays results. Transforming growth factor-β (TGF-β) signaling pathway was the most significantly enriched pathway. The constructed ceRNA network suggested that RP5-875H18.4--miRNA-218--SLIT2 had a potential ceRNA regulatory mechanism in PAS. CONCLUSIONS The differentially expressed lncRNAs are involved in the occurrence and progression of PAS possibly by regulating the TGF-β signaling pathway. The ceRNA network of RP5-875H18.4--miRNA-218--SLIT2 may play a role in the occurrence of PAS.

The effects of placental long noncoding RNA H19 polymorphisms and promoter methylation on H19 expression in association with preeclampsia susceptibility. IUBMB Life 2019; 72:413-425.

Abstract
The effect of DNA methylation on gene expression triggered it as a susceptibility factor in various diseases including preeclampsia (PE). The pathogenesis of PE is closely associated with the methylation status and genetic variants of relevant genes. Therefore, the aim of the study was to investigate the possible impacts of the placental DNA methylation and rs3741219, rs217727, and rs2107425 polymorphisms of the H19 gene on the PE susceptibility as well as the its mRNA expression. Moreover, eight haplotypes of three loci in the H19 gene were analyzed. In this case-control study, the placentas of 107 preeclamptic and 113 non-preeclamptic women were collected after delivery. The methylation status was assessed by methylation-specific polymerase chain reaction (PCR). The H19 polymorphisms were genotyped using polymerase chain reaction-restriction fragment length polymorphism or amplification refractory mutation system-polymerase chain reaction methods. The quantitative real time PCR was used for mRNA expression assay. The placental H19 rs3741219 and rs2107425 polymorphisms were not associated with PE. However, H19 rs217727CT and TT genotypes might be associated with a 9.2- and 17.7-fold increased risk of PE, respectively. The Trs3741219 Crs217727 Crs2107425 and Trs3741219 Crs217727 Trs2107425 haplotypes were significantly lower, whereas the Trs3741219 Trs217727 Crs2107425 and Crs3741219 Trs217727 Crs2107425 haplotypes were significantly higher in PE women. Promoter but not upstream region hypermethylation of H19 gene could be led to decreased risk of PE (MM vs. UM + UU). No significant difference was observed in the placental mRNA expression between two groups. The H19 expression was significantly higher in women with unmethylated (UU), compared to methylated promoter (MM). The H19 expression was 17- and 15-fold higher in H19-rs2107425 CC and CT genotypes in PE women. In conclusion, the H19 rs2107425 polymorphism was associated with a higher risk of PE and increased H19 mRNA expression. The promoter hypermethylation of H19 gene was associated with a lower risk of PE and decreased H19 mRNA expression.
