Abstract
Triphenyl phosphate (TPhP) is an organophosphate flame retardant that is widely used in many commercial products. The United States Environmental Protection Agency has listed TPhP as a priority compound that requires health risk assessment. We previously found that TPhP could accumulate in the placentae of mice and impair birth outcomes by activating peroxisome proliferator-activated receptor gamma (PPARγ) in the placental trophoblast. However, the underlying mechanism remains unknown. In this study, we used a mouse intrauterine exposure model and found that TPhP induced preeclampsia (PE)-like symptoms, including new on-set gestational hypertension and proteinuria. Immunofluorescence analysis showed that during placentation, PPARγ was mainly expressed in the labyrinth layer and decidua of the placenta. TPhP significantly decreased placental implantation depth and impeded uterine spiral artery remodeling by activating PPARγ. The results of the in vitro experiments confirmed that TPhP inhibited extravillous trophoblast (EVT) cell migration and invasion by activating PPARγ and inhibiting the PI3K-AKT signaling pathway. Overall, our data demonstrated that TPhP could activate PPARγ in EVT cells, inhibit cell migration and invasion, impede placental implantation and uterine spiral artery remodeling, then induce PE-like symptom and impair birth outcomes. Although the exposure doses used in this study was several orders of magnitude higher than human daily intake, our study highlights the placenta as a potential target organ of TPhP worthy of further research.

Abstract
Precise extravillous trophoblast (EVT) invasion is crucial for successful placentation and pregnancy. This review focuses on elucidating the mechanisms that promote heightened EVT invasion. We comprehensively summarize the pivotal roles of hormones, angiogenesis, hypoxia, stress, the extracellular matrix microenvironment, epithelial-to-mesenchymal transition (EMT), immunity, inflammation, programmed cell death, epigenetic modifications, and microbiota in facilitating EVT invasion. The molecular mechanisms underlying enhanced EVT invasion may provide valuable insights into potential pathogenic mechanisms associated with diseases characterized by excessive invasion, such as the placenta accreta spectrum (PAS), thereby offering novel perspectives for managing pregnancy complications related to deficient EVT invasion.

Abstract
INTRODUCTION Ubiquitination is a significant post-translational modification engaged in diverse biological processes, such as cell differentiation, metastasis, and protein stability modulation. The dysregulation of ubiquitination and deubiquitination is inextricably linked to disease progression, including preeclampsia (PE). Ubiquitin-specific protease 17 (USP17), a prominent deubiquitinating enzyme that regulates ubiquitination modifications, performs multiple functions at the cellular level, whereas its role in PE remains elusive. In this study, we intended to probe the role of USP17 in PE and its underlying mechanisms. METHODS The USP17 level in the plasma of PE patients was detected through Elisa. Western blot and qRT-PCR were performed to measure the mRNA and protein level of USP17 in placental tissues. CCK-8, EdU, and transwell assays were conducted to evaluate the proliferation, migration, and invasion of trophoblast cells. The interaction between HDAC2 and USP17 or STAT1 were determined by co-immunoprecipitation and Western blot assays. The expression of NF-κB pathway related proteins was examined using Western blot. RESULTS USP17 was dramatically downregulated in PE patients. Overexpression of USP17 facilitated trophoblast proliferation, migration, and invasion. Moreover, histone deacetylase 2 (HDAC2) was validated as a substrate of USP17 deubiquitination, and USP17 upregulation enhanced HDAC2 protein level. Furthermore, HDAC2 could interact with and deacetylate Signal transducer and activator of transcription 1 (STAT1), resulting in the enhancement of STAT1 activity and inhibition of NF-κB signaling. DISCUSSION Our findings disclosed that USP17 augmented the proliferation and invasion of trophoblast by deubiquitinating HDAC2, which will contribute to novel prospective targets for diagnosing and treating PE.

Abstract
Despite its low frequency, osteosarcoma is one of the deadliest malignancies in children and adolescents. The phosphatidylinositol 3-kinase (PI3K)/Akt signaling activation and epithelial-to-mesenchymal transition (EMT) are critical issues during osteosarcoma development. This study found long intergenic non-protein coding RNA 1060 (LINC01060) to be an EMT-related long non-coding RNA (lncRNA) up-regulated in osteosarcoma; higher LINC01060 expression was linked to a worse prognosis in osteosarcoma patients. In vitro, knocking down LINC01060 significantly inhibits osteosarcoma cell malignant behaviors, including hyperproliferation, invasion, migration, and EMT. In vivo, LINC01060 knockdown inhibited tumor growth and metastasis, and suppressed PI3K and Akt phosphorylation. In osteosarcoma cells, Akt agonist SC79 exerted opposite effects to those of LINC01060 knockdown through the promotion of cell viability, cell migration, and cell invasion. Moreover, the Akt agonist SC79 partially eliminated LINC01060 knockdown effects on osteosarcoma cells, suggesting that LINC01060 exerts its effects through the PI3K/Akt signaling. Therefore, it is deduced that LINC01060 is overexpressed in osteosarcoma. In vitro, LINC01060 knockdown inhibits cancer cell malignant behaviors; in vivo, LINC01060 knockdown inhibits tumor development and metastasis. The PI3K/Akt signaling is involved in LINC01060 functions in osteosarcoma.

Abstract
In this study, we compared the placental T-cadherin staining intensity of pregnant women with placenta percreta (PP) and asymmetrical fetal growth restriction (FGR) compared with healthy control pregnancies. Placental T-cadherin levels of the placenta of 86 pregnant women in total, 25 with FGR, 30 with healthy pregnant subjects, and 31 with PP, were examined using monoclonal anti-T-cadherin (CDH13) antibody for immunohistochemical examination. In immunohistochemistry, H -scores were used for each group to compare the expression of T-cadherin in extravillous trophoblast (EVT) cells. T-cadherin H -score of EVTs was highest in the FGR group and the lowest in the PP group. The difference in H -score between the FGR group and the control group was not statistically significant ( P =0.344). The difference between the PP group and the other 2 groups was significant ( P <0.0001). Multivariable linear regression analysis with a stepwise elimination method was performed in order to identify demographic and clinical parameters with significant effects on the T-cadherin H -score of EVTs. The estimation results identified only the disease group as a significant predictor of the H -score of EVTs ( R2 =0.340, P <0.0001). The highest T-cadherin H -score of EVTs was found in the FGR group and the lowest in the PP group. The low T-cadherin H-score values in the PP group suggest that low T-cadherin EVTs may be associated with increased placental invasion. Likewise, despite the statistical insignificance, a higher T-cadherin H -score of EVTs in FGR compared with controls implies a decreased invasiveness of the placenta in FGR.

Abstract
Placental dysfunction refers to the insufficiency of placental perfusion and chronic hypoxia during early pregnancy, which impairs placental function and causes inadequate supply of oxygen and nutrients to the fetus, affecting fetal development and health. Fetal intrauterine growth restriction, one of the most common outcomes of pregnancy-induced hypertensions, can be caused by placental dysfunction, resulting from deficient trophoblast syncytialization, inadequate trophoblast invasion and impaired vascular remodeling. During placental development, cytotrophoblasts fuse to form a multinucleated syncytia barrier, which supplies oxygen and nutrients to meet the metabolic demands for fetal growth. A reduction in the cell fusion index and the number of nuclei in the syncytiotrophoblast are found in the placentas of pregnancies complicated by IUGR, suggesting that the occurrence of IUGR may be related to inadequate trophoblast syncytialization. During the multiple processes of trophoblasts syncytialization, specific proteins and several signaling pathways are involved in coordinating these events and regulating placental function. In addition, epigenetic modifications, cell metabolism, senescence, and autophagy are also involved. Study findings have indicated several abnormally expressed syncytialization-related proteins and signaling pathways in the placentas of pregnancies complicated by IUGR, suggesting that these elements may play a crucial role in the occurrence of IUGR. In this review, we discuss the regulators of trophoblast syncytialization and their abnormal expression in the placentas of pregnancies complicated by IUGR.

Abstract
Preeclampsia (PE) is a common pregnancy-specific syndrome with an incidence of 4.6% in all pregnant women. Numerous studies have uncovered the functions and mechanisms of microsomal glutathione transferase 1 (MGST1) in different diseases and cellular processes, but whether MGST1 plays a role in PE remains unclear. Our study aimed to investigate the regulatory role of MGST1 in PE progression. In this study, the HTR8/SVneo cells were incubated with CoCl2 (250 µM) to mimic hypoxia in trophoblasts. Real-time quantitative polymerase chain reaction revealed that MGST1 was dramatically reduced in the placenta of PE patients. The proliferation of HTR8/SVneo cells was assessed via the Cell Counting Kit-8 and colony formation assays, and the results showed that MGST1 upregulation increased the cell viability of HTR8/SVneo cells. In addition, wound healing and Transwell assays unveiled that the elevation of MGST1 enhanced trophoblast cell migration and invasion. Moreover, the upregulation of MGST1 alleviated the hypoxia-induced oxidative stress in trophoblast cell. Mechanically, we found that MGST1 regulated PE progression by activating the phosphoinositide-3-kinase/protein kinase B/mechanistic target of rapamycin (PI3K/AKT/mTOR) pathway. In conclusion, MGST1 alleviated the oxidative stress of trophoblast cells induced by hypoxia/reoxygenation and promoted cell proliferation, migration, and invasion via the activation of the PI3K/AKT/mTOR pathway in PE. These results suggested that MGST1 can be a potential target for the prevention and treatment of PE.

Abstract
Preeclampsia is a complex disease of pregnancy whose physiopathology remains unclear. We developed machine-learning models for early prediction of preeclampsia (first 16 weeks of pregnancy) and over gestation by analyzing six omics datasets from a longitudinal cohort of pregnant women. For early pregnancy, a prediction model using nine urine metabolites had the highest accuracy and was validated on an independent cohort (area under the receiver-operating characteristic curve [AUC] = 0.88, 95% confidence interval [CI] [0.76, 0.99] cross-validated; AUC = 0.83, 95% CI [0.62,1] validated). Univariate analysis demonstrated statistical significance of identified metabolites. An integrated multiomics model further improved accuracy (AUC = 0.94). Several biological pathways were identified including tryptophan, caffeine, and arachidonic acid metabolisms. Integration with immune cytometry data suggested novel associations between immune and proteomic dynamics. While further validation in a larger population is necessary, these encouraging results can serve as a basis for a simple, early diagnostic test for preeclampsia.

Abstract
Chronic hypoxia can cause fetal growth restriction (FGR) through placental dysfunction. Insulin-like growth factors (IGFs), such as IGF-2, play a major role in preservation of placental growth and function. We investigated the effects of chronic hypoxia and sex on protein expression of the IGF-2 pathway in placentas selected from asymmetric-FGR fetuses. Time-mated pregnant guinea pigs were assigned to normoxia (NMX, 21% O2) or hypoxia (HPX, 10.5% O2) during the last 14 days of pregnancy. Placentas were selected from male and female symmetrically grown NMX fetuses (fetal wt between 25th ile-75th ile) and HPX fetuses of asymmetric-FGR (fetal wt < 25th ile and brain:liver wt > 50th ile). Effects of HPX and sex on placenta protein expression of the IGF-2 signaling proteins (IGF-2, PI3K, AKT-P, total AKT, PCNA, a cell proliferation marker) were evaluated by immunoblotting. Effects of HPX and sex on morphometric parameters were analyzed using two-way ANOVA (p < 0.05). HPX reduced (p < 0.005) fetal wt by ~ 35% compared to NMX in both sexes. Expression of IGF-2 was lower (p = 0.029) in NMX female placentas compared to males. Despite lower NMX levels, HPX increased (p < 0.05) expression of IGF-2, AKT-P, relative AKT-P, and PCNA in female placentas only and had no effect on protein expression in male placentas. The female guinea pig placenta exhibits a greater sensitivity than males to HPX in upregulating expression of the IGF-2 axis. In addition, the sex difference in baseline IGF-2 expression suggests a greater capacity for females to increase IGF-2 in response to HPX as a placental adaptation in FGR.

ENVIRONMENTAL POLLUTION (BARKING, ESSEX : 1987) 2022; 307:119495.

Abstract
Ethalfluralin, a dinitroaniline-type herbicide, has been used for decades. As a result, its residues are detected on some farmlands. To determine the molecular mechanisms underlying the detrimental effects of ethalfluralin on early pregnancy, porcine luminal epithelium and trophectoderm cell lines were used. Ethalfluralin was found to inhibit the viability, proliferation, and migration of porcine luminal epithelial (pLE) and porcine trophectoderm (pTr) cells. Additionally, ethalfluralin induced apoptotic cell death by means of an imbalance in calcium homeostasis in both pLE and pTr cells. Ethalfluralin decreased mitochondrial membrane potential (ΔΨm) and impaired mitochondrial respiration by downregulating the mitochondrial respiratory complex-related genes. Ethalfluralin also activated endoplasmic reticulum stress signals and autophagy pathways, increased the phosphorylation of P38 MAPK and NF-κB, and suppressed the PI3K/AKT signaling pathway. Taken together, this study elucidated the molecular mechanisms by which ethalfluralin impedes the viability and mitochondrial function in fetal trophectoderm and maternal endometrial cells during early pregnancy.

Abstract
Robust evidence of fetal programming of adult disease has surfaced in the last several decades. Human and preclinical investigations of intrauterine insults report perturbations in placental nutrient sensing by the mechanistic target of rapamycin (mTOR). This review focuses on pregnancy complications associated with placental mTOR regulation, such as fetal growth restriction (FGR), fetal overgrowth, gestational diabetes mellitus (GDM), polycystic ovarian syndrome (PCOS), maternal nutrient restriction (MNR), preeclampsia (PE), maternal smoking, and related effects on offspring birthweight. The link between mTOR-associated birthweight outcomes and offspring metabolic health trajectory with a focus on sexual dimorphism are discussed. Both human physiology and animal models are summarized to facilitate in depth understanding. GDM, PCOS and fetal overgrowth are associated with increased placental mTOR, whereas FGR, MNR and maternal smoking are linked to decreased placental mTOR activity. Generally, birth weight is reduced in complications with decreased mTOR (i.e., FGR, MNR, maternal smoking) and higher with increased mTOR (GDM, PCOS). Offspring display obesity or a higher body mass index in childhood and adulthood, impaired glucose and insulin tolerance in adulthood, and deficiencies in pancreatic beta-cell mass and function compared to offspring from uncomplicated pregnancies. Defining causal players in the fetal programming of offspring metabolic health across the lifespan will aid in stopping the vicious cycle of obesity and type II diabetes.

Abstract
Recurrent spontaneous abortion (RSA) effects both the physical and mental health of women of reproductive age. Trophoblast dysfunction may result in RSA due to shallow placental implantation. The mechanisms underlying formyl peptide receptor 2 (FPR2) on the biological functions of trophoblasts remain to be elucidated. The present study aimed to explore the potential functions of FPR2, a G protein‑coupled receptor, in placental trophoblasts. The location and expression levels of FPR2 in the villi tissue of patients with RSA were detected using immunohistochemical staining, reverse transcription‑quantitative PCR and western blotting. Following the transfection of small interfering RNA targeting FPR2 in HTR‑8/SVneo cells, a Cell Counting Kit‑8 assay was used to determine the levels of cell viability. Flow cytometry was used to examine the levels of cell apoptosis and gap closure and Transwell assays were carried out to evaluate the levels of cell migration and invasion. A tube formation assay was performed to detect the levels of capillary‑like structure formation. Western blotting was used to detect the expression levels of proteins in the associated signaling pathways. The expression of FPR2 was present in villi trophoblasts and was markedly increased in patients with RSA. The levels of trophoblast invasion, migration and tube formation were markedly increased following FPR2 knockdown, whereas the levels of apoptosis were markedly decreased. In addition, FPR2 knockdown caused an increase in the phosphorylation levels of AKT and PI3K. Thus, FPR2 may be involved in the regulation of trophoblast function via the PI3K/AKT signaling pathway. The results of the present study provided a theoretical basis for the use of FPR2 as a target for the treatment of trophoblast‑associated diseases, such as RSA.

Abstract
Preeclampsia is the main reason for maternal and fetal deaths during the second half of pregnancy. Trophoblast cells play a pivotal role in preeclampsia progression. Circular RNA (circRNA) circ_0111277 has been reported to be related to the development of trophoblast cells. This study is designed to explore the role and mechanism of circ_0111277 on trophoblast cell behavior in preeclampsia. Circ_0111277, microRNA-424-5p (miR-424-5p), and nuclear factor of activated T-cell 5 (NFAT5) levels were measured by real-time quantitative polymerase chain reaction (RT-qPCR). Cell viability, migration, invasion, and angiogenesis were measured by 3-(4, 5-dimethyl-2-thiazolyl)-2, 5-diphenyl-2-H-tetrazolium bromide (MTT) assay, transwell assay, tube formation assay, and wound healing assay. Protein levels of matrix metallopeptidase 2 (MMP2), vascular endothelial growth factor-A (VEGF-A), NFAT5, phospho-phosphatidylinositol 3 kinase (p-PI3K), PI3K, phospho-protein kinase B (p-AKT), and AKT were examined by western blot assay. The binding relationship between miR-424-5p and circ_0111277 or NFAT5 was predicted by circBank or starBase and then verified by a dual-luciferase reporter assay. Circ_0111277 and NFAT5 expression were increased in placenta tissues of preeclampsia patients, and miR-424-5p was decreased. Moreover, circ_0111277 knockdown could boost cell viability, migration, invasion, and angiogenesis in trophoblast cells. The mechanical analysis discovered that circ_0111277 acted as a sponge of miR-424-5p to regulate NFAT5 expression. Besides, circ_0111277 silencing promoted the PI3K/AKT signaling pathway in trophoblast cells. Circ_0111277 downregulation could facilitate cell growth and metastasis in trophoblast cells partly by regulating the miR-424-5p/NFAT5 axis, providing an underlying circRNA-targeted therapy for preeclampsia.

Abstract
Background Preeclampsia (PE) is a complex pregnancy-related disease that endangers the safety of maternal and fetal. The purpose of this study is to reveal the pathogenesis of preeclampsia and discover new predictors from the perspective of peptidomics. The umbilical cord blood of PE and control group was analyzed by peptidomics. A peptide named Regulation of Proliferation Process in Preeclampsia (ROPPIP) was screened out to explore its role in the proliferation, migration and apoptosis of trophoblast cells in preeclampsia. Methods We compared and analyzed the umbilical cord blood of patients with PE and normal pregnant women using liquid chromatography-tandem mass spectrometry (LC-MS). hTR-8/Svneo cells cultured in vitro were divided into ROPPIP group and a disordered peptide group as control. Cell Counting Kit-8 (CCK-8) assay, flow cytometry, Transwell chamber assays and western blot analysis were performed to detect cell proliferation, invasion, migration and apoptosis, in addition to the expression of Matrix metalloproteinase-2 (MMP2), nuclear associated antigen Ki67, B-cell lymphoma-2 (Bcl2), Caspase 3, and β-actin protein. Results We identified 133 differential peptides. Of these, 51 were up-regulated while 82 were down-regulated. the polypeptide SFGVRMATASPTDGNV with low differential expression in the serum of PE patients was selected for the study, we named the polypeptide as Regulation of Proliferation Process in PE (ROPPIP). The experiment shows that ROPPIP can up-regulate the expression levels of MMP2, Ki67, and Bcl2 in HTR-8/Svneo cells, down-regulate the expression of caspase-3, promote the proliferation and migration of HTR-8/Svneo cells and inhibit the apoptosis induced by cisplatin, the activation of the phosphatidylinositol-3-kinase/protein kinase B/mammalian target of rapamycin (PI3K/Akt/mTOR) signaling pathway may be associated with the function of ROPPIP. Conclusions ROPPIP promotes HTR-8/Svneo cells migration and proliferation, and inhibits apoptosis, by regulating the activation of the PI3K/AKT/mTOR signaling pathway.

Abstract
Pre‐eclampsia (PE) is a worldwide pregnancy‐related disorder. It is mainly characterized by defect migration and invasion of trophoblast cells. Recently, circular RNAs (circRNAs) have been believed to play a vital role in PE. The expression patterns and the biological functions of circRNAs in PE remain elusive. Here, we performed a circRNA microarray to identify putative PE‐related circRNAs. Bioinformatics analyses were used to screen the circRNAs which have potential relationships with pre‐eclampsia, and we identified a novel circRNA (circVRK1) that was up‐regulated in PE placenta tissues. By using HTR‐8/SVneo cells, circVRK1 knockdown significantly enhanced cell migration and invasion abilities, as well as epithelial‐mesenchymal transition (EMT). Mechanistically, we found that circVRK1 and PTEN could function as the ceRNAs to miR‐221‐3p. Overexpression of miR‐221‐3p promoted cell migration, invasion and EMT via regulating PTEN. The cotransfection of miR‐221‐3p inhibitor or PTEN reversed the effect from circVRK1 knockdown. Moreover, the circVRK1/miR‐221‐3p/PTEN axis greatly regulated Akt phosphorylation. In general, circVRK1 suppresses trophoblast cell migration, invasion and EMT, by acting as a ceRNA to miR‐221‐3p to regulate PTEN, and further inhibit PI3K/Akt activation. The purpose of this paper is to open wide insights to investigate the onset of PE and provide new potential therapeutic targets in PE.

Abstract
Osteosarcoma (OS) is the most common malignancy that occurs mainly during childhood and adolescence; however, no clear molecular or biological mechanism has been identified. In this study, we aimed to explore new biomarkers for the early diagnosis, targeted treatment, and prognostic determination of osteosarcoma. We first used bioinformatics analysis to show that KIF21B can be used as a biomarker for the diagnosis and prognosis of osteosarcoma. We then examined the expression of KIF21B in human osteosarcoma tissues and cell lines using immunohistochemistry, western blotting, and qRT-PCR. It was found that KIF21B expression was significantly upregulated in osteosarcoma tissues and cell lines. After knocking down the expression of KIF21B in the osteosarcoma cell lines 143B and U2-OS, we used cell fluorescence counting, CCK-8 assays, flow cytometry, and TUNEL staining to examine the effects of KIF21B on osteosarcoma cell proliferation and apoptosis. The results demonstrated that knocking down KIF21B in 143B and U2-OS cells could increase cell apoptosis, inhibit cell proliferation, and reduce tumor formation in nude mice. Subsequently, we used gene chips and bioinformatics to analyze the differential gene expression caused by knocking down KIF21B. The results showed that KIF21B may regulate OS cell proliferation and apoptosis by targeting the PI3K/AKT pathway. We then examined the expression of PI3K/AKT- and apoptosis-related proteins using western blotting. KIF21B knockdown inhibited the PI3K pathway, downregulated Bcl-2, and upregulated Bax. Moreover, the use of PI3K/AKT pathway agonists reversed the regulatory effect of KIF21B on the apoptosis and proliferation of 143B and U2-OS cells. In conclusion, our results indicated that KIF21B plays a key role in osteosarcoma. Low KIF21B expression might indirectly increase the apoptosis and inhibit the proliferation of osteosarcoma cells through the PI3K/AKT pathway.

Abstract
Placental hypoxia has been implicated in pregnancy pathologies such as pre-eclampsia and intrauterine growth restriction. However, the underlying mechanism by which the trophoblasts respond to hypoxia remains unclear. Speckle-type POZ protein (SPOP), an E3 ubiquitin ligase adapter, was previously reported to play important roles in various physiological and pathological processes. This study aims to investigate the expression and biological functions of SPOP after exposure to cobalt chloride (CoCl2 )-mimicked hypoxia conditions using human trophoblast-derived choriocarcinoma cell lines and extravillous cytotrophoblast. These data showed that SPOP protein was directly induced by CoCl2 -mimicked hypoxia and regulated by HIF-1α at the posttranscription level. CoCl2 treatment could dramatically influence the localization of SPOP in trophoblasts, especially the accumulation of SPOP into the nucleus. In addition, both CoCl2 -mimicked hypoxia and induction of endogenous SPOP expression by lentivirus transfection attenuated the migration and invasion abilities of trophoblasts. Furthermore, we demonstrated that SPOP was involved in CoCl2 -induced the inhibition of the PI3K/AKT/GSK3β pathway in placental trophoblasts. Taken together, these data indicate that accumulation of HIF-1α augments the expression of SPOP in trophoblasts, which impairs trophoblastic mobility by targeting the PI3K/AKT/GSK3β pathway. This potentially leads to insufficient uterine spiral artery remodeling and suboptimal placental perfusion, and thus the development of pregnancy-related complication.

Abstract
To investigate the heterogeneity of decidual stromal cells (DSCs) and their functional alterations during delivery, we conducted single-cell RNA sequencing analysis to characterize the transcriptomic profiles of DSCs before and after labor onset. According to their transcriptomic profiles, DSCs (6382 cells) were clustered into five subgroups with different functions. Similar to stromal cells, cells in cluster 1 were involved in cell substrate adhesion. On the other hand, cells in clusters 2 and 3 were enriched in signal transduction-related genes. Labor onset led to significant alterations in many pathways, including the activator protein 1 pathway (all clusters), as well as in the response to lipopolysaccharide (clusters 1-3). The downregulated genes were involved in coagulation, ATP synthesis, and oxygen homeostasis, possibly reflecting the oxygen and energy balance during delivery. Our findings highlight that peripartum DSCs are heterogeneous and play multiple roles in labor.

Abstract
INTRODUCTION Many studies have shown that circular RNAs (circRNAs) are related to the occurrence of preeclampsia (PE). However, the role of circLRRK1 in the progression of PE is unclear. METHODS The identification and localization of circLRRK1 were verified by Actinomycin D (ActD) assay, Ribonuclease R (RNase R) digestion assay and subcellular localization assay. Moreover, the proliferation of trophoblast cells was detected by 3-(45)-dimethylthiahiazo (-z-y1)-35-di-phenytetrazoliumromide (MTT) assay and colony formation assay. Furthermore, the migration and invasion of trophoblast cells were determined by wound healing assay and transwell assay. Meanwhile, Western blot (WB) analysis was used to examine the protein levels of migration markers and PI3K/AKT signaling pathway markers. In addition, the interaction between circLRRK1 and miR-223-3p was confirmed by dual-luciferase reporter assay and biotin-labeled RNA pull-down assay. RESULTS Our results showed that circLRRK1 was significantly highly expressed in PE patients. Silenced circLRRK1 could markedly enhance the proliferation, migration and invasion of trophoblast cells. Additionally, we found that circLRRK1 could target miR-223-3p. MiR-223-3p overexpression also promoted the proliferation, migration and invasion of trophoblast cells. The rescue experiments revealed that miR-223-3p inhibitor could reverse the promoting effect of circLRRK1 silencing on the proliferation, migration and invasion of trophoblast cells. Furthermore, circLRRK1 silencing could activate the PI3K/AKT signaling pathway by targeting miR-223-3p. DISCUSSION CircLRRK1 could suppress the proliferation, migration and invasion of trophoblast cells by regulating the PI3K/AKT signaling pathway via targeting miR-223-3p, suggesting that circLRRK1 might be a potential biomarker for the treatment of PE.

Abstract
Insufficient trophoblast invasion has been shown to contribute to the occurrence and progression of preeclampsia (PE). Recently, beta-transducin repeat containing E3 ubiquitin protein (β-TrCP) was shown to function as a ubiquitination regulator in regulating the proliferation and invasion of various cell types. In this study, we employed an in vitro model of trophoblasts to investigate the role played by β-TrCP in the pathogenesis of PE. The levels of β-TrCP in newly delivered placentas from 15 pregnant women with PE and 15 healthy pregnant women were detected by quantitative real-time PCR and western blot assays. The effects of β-TrCP on cell migration, invasion, and epithelial-mesenchymal transition (EMT) in two trophoblast cell lines (HTR-8/SVneo and TEV-1) were examined using wound healing assays, Transwell assays, and western blot assays, respectively. Rescue experiments were performed by treating β-TrCP knockdown or β-TrCP expressing trophoblasts with si-Snail transfection or a proteasome inhibitor (MG132). β-TrCP mRNA and protein expression levels were significantly increased in the PE placentas when compared to the normal control placentas. β-TrCP overexpression significantly inhibited cell migration and invasion, while silencing of β-TrCP promoted cell migration and invasion of the two trophoblast cell lines. Furthermore, we demonstrated that β-TrCP-mediated ubiquitination might inhibit the EMT process of trophoblasts by down-regulating Snail expression. Our results suggest that both β-TrCP mRNA and protein expression were up-regulated in the PE placentas. β-TrCP impeded the migration and invasion of trophoblasts by suppressing Snail expression. This implicates the ubiquitin-proteasome pathway in the pathogenesis of PE, and suggests β-TrCP as a potential target for treating PE.

Abstract
Extravillous trophoblast remodeling of the uterine spiral arteries is essential for promoting blood flow to the placenta and fetal development, but little is known about the regulation of this process. A defect in spiral artery remodeling underpins adverse conditions of human pregnancy, notably early-onset preeclampsia and fetal growth restriction, which result in maternal and fetal morbidity and mortality. Many in vitro studies have been conducted to determine the ability of growth and other factors to stimulate trophoblast cells to migrate across a synthetic membrane. Clinical studies have investigated whether the maternal levels of various factors are altered during abnormal human pregnancy. Animal models have been established to assess the ability of various factors to recapitulate the pathophysiological symptoms of preeclampsia. This review analyzes the results of the in vitro, clinical, and animal studies and describes a nonhuman primate experimental paradigm of defective uterine artery remodeling to study the regulation of vessel remodeling.

Abstract
Preeclampsia (PE) is a serious disease during pregnancy associated with the dysfunction of trophoblast cell invasion. DDX46 is a kind of RNA helicase that has been found to regulate cancer cell metastasis. However, the role of DDX46 in PE remains unclear. Our results showed that the mRNA levels of DDX46 in placental tissues of pregnant women with PE were markedly lower than those in normal pregnancies. Loss-of-function assays showed that knockdown of DDX46 significantly suppressed cell proliferation of trophoblast cells. Besides, DDX46 knockdown decreased trophoblast cell migration and invasion capacity. In contrast, the overexpression of DDX46 promoted the migration and invasion of trophoblast cells. Furthermore, knockdown of DDX46 caused significant decrease in the levels of p-PI3K, p-Akt, and p-mTOR in HTR-8/SVneo cells. In addition, treatment with IGF-1 reversed the inhibitory effects of DDX46 knockdown on proliferation, migration, and invasion of HTR-8/SVneo cells. In conclusion, these data suggest that DDX46 might be involved in the progression of PE, which might be attributed to the regulation of PI3K/Akt/mTOR signaling pathway. Thus, DDX46 might serve as a therapeutic target for the treatment of PE.

Abstract
Irisin, an adipokine, regulates differentiation and phenotype in various cell types including myocytes, adipocytes, and osteoblasts. Circulating irisin concentration increases throughout human pregnancy. In pregnancy disorders such as preeclampsia and gestational diabetes mellitus, circulating irisin levels are reduced compared to healthy controls. To date, there are no data on the role and molecular function of irisin in the human placenta or its contribution to pathophysiology. Aberrant trophoblast differentiation is involved in the pathophysiology of preeclampsia. The current study aimed to assess the molecular effects of irisin on trophoblast differentiation and function. First-trimester placental explants were cultured and treated with low (10 nM) and high (50 nM) physiological doses of irisin. Treatment with irisin dose-dependently increased both in vitro placental outgrowth (on Matrigel™) and trophoblast cell-cell fusion. Adenosine monophosphate-activated protein kinase (AMPK) signaling, an important regulator of cellular energy homeostasis that is involved in trophoblast differentiation and pathology, was subsequently investigated. Here, irisin exposure induced placental AMPK activation. To determine the effects of irisin on trophoblast differentiation, two trophoblast-like cell lines, HTR-8/SVneo and BeWo, were treated with irisin and/or a specific AMPK inhibitor (Compound C). Irisin-induced AMPK phosphorylation in HTR-8/SVneo cells. Additionally, as part of the differentiation process, integrin switching from α6 to α1 occurred as well as increased invasiveness. Overall, irisin promoted differentiation in villous and extravillous cell-based models via AMPK pathway activation. These findings provide evidence that exposure to irisin promotes differentiation and improves trophoblast functions in the human placenta that are affected in abnormal placentation.
