Abstract
Leucine-rich repeat-containing G protein-coupled receptors 5/4 (LGR5/LGR4) are critical stem cell markers in epithelial tissues including intestine. They agonise wingless-related integration site (WNT) signalling. Until now, LGR5/LGR4 were uncharacterised in placenta, where analogous functions may exist. We characterised LGR5/LGR4, their ligands/targets in human placenta, with further assessments on dysregulation in preeclampsia/fetal growth restriction (FGR). LGR5 mRNA was unaltered in first trimester (n = 11), preterm (n = 9) and term (n = 11) placental lysate. LGR5 was enriched in human trophoblast stem cells (hTSCs) and downregulated with differentiation to extravillous trophoblasts (p < 0.0215) and syncytiotrophoblasts (p < 0.0350). In situ hybridisation localised LGR5 to unique, proliferative MKI67 + mononuclear trophoblasts underlying syncytium which concurred with proposed progenitor identities in single-cell transcriptomics. LGR5 expression was significantly reduced in placentas from early-onset preeclampsia (p < 0.0001, n = 81 versus n = 19 controls), late-onset preeclampsia (p = 0.0046, n = 20 versus n = 33 controls) and FGR (p = 0.0031, n = 34 versus n = 17 controls). LGR4 was elevated in first trimester versus preterm and term placentas (p = 0.0412), in placentas with early-onset preeclampsia (p = 0.0148) and in FGR (p = 0.0417). Transcriptomic analysis and in vitro hTSC differentiation to both trophoblast lineages suggested LGR4 increases with differentiation. Single-nucleus RNA sequencing of placental villous samples supported LGR5 and LGR4 localisation findings. Hypoxia/proinflammatory cytokine treatment modelling elements experienced by the placenta in placental insufficiency pathogenesis did not significantly alter LGR5/LGR4. Ligands R-spondins 1/3/4, and neutralising targets ring finger protein 43 (RNF43) and zinc and ring finger 3 (ZNRF3) were also reduced in placentas from preeclamptic pregnancies. This study is the first to describe LGR5/LGR4 and their signalling partner expression in human placenta. Their dysregulations in the preeclamptic placenta allude to disruptions to integral trophoblast stem cell function/differentiation that may occur during placental development related to WNT signalling.

Biol Reprod 2025; 112:375-391. [PMID: 39561117 PMCID: PMC11833490 DOI: 10.1093/biolre/ioae168] [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: 07/21/2024] [Revised: 09/30/2024] [Accepted: 11/15/2024] [Indexed: 11/21/2024] Open
Abstract
Visfatin regulates energy homeostasis, metabolism, inflammation, and reproduction via the hypothalamus-pituitary-ovary axis. Our previous study showed the visfatin gene and protein expression in the human placenta. This study aimed to investigate the in vitro effect of visfatin on the proliferation and apoptosis of placental JEG-3 and BeWo cells but also in villous explants collected from normal pregnancies and complicated by intrauterine growth restriction (IUGR), preeclampsia (PE), and gestational diabetes mellitus (GDM). We studied placenta cells viability, proliferation, cell cycle, proliferation/apoptotic factors and insulin receptor (INSR) expression, DNA fragmentation, CASP3/7 activity, and phosphorylation of ERK1/2, AKT, AMPKα, STAT3 with their involvement after pharmacological inhibition in visfatin action on proliferation and apoptosis. Visfatin (1, 10, 100 ng/mL) decreased the viability and proliferation of JEG-3 after 48 h, and a similar effect was observed via co-administration of visfatin (10 ng/mL) and insulin (10 ng/mL) in JEG-3 and BeWo after 48 h and 72 h, respectively. Visfatin reduced the transition from the G2/M phase, and expression of PCNA or cyclins D, E, A, and B in JEG-3 and PCNA in normal, IUGR, PE, and GDM placentas. It increased DNA fragmentation, CASP3/7 activity, P53, BAX/BCL2, CASP9, CASP 8, CASP3 levels in BeWo, and CASP3 expression in tested placentas. Furthermore, visfatin modulated INSR, ERK1/2, AKT, AMPKα, and STAT3 expression in JEG-3 and BeWo, and its anti-proliferative and pro-apoptotic effects occurred via mentioned factors. In conclusion, visfatin, by affecting the proliferation and apoptosis of human placenta cells, may be an important factor in the development and function of the organ.

Abstract
Studies on DNA methylation alterations associated with pre-eclampsia (PE) have improved our understanding of the mechanisms underlying this disorder. However, differentially methylated cytosines (DMCs) have not been adjusted for cell-type heterogeneity, hampering the identification of alterations that drive disease risk. Using a reference-based, cell-type deconvolution approach, we estimated the nuclear proportions of 335 placental samples based on DNA methylation data. We found that the nuclei of total trophoblast lineages accounted for more than 80% of the placental samples, with a significant increase in PE placentas. The nuclear proportions of stromal and Hofbauer cells decreased in PE placentas. Our nuclear proportion estimation reflected previous histological knowledge on the changes in cell type proportions in PE placentas. We corrected 2125 DMCs associated with early-onset PE for cell-type heterogeneity by adjusting for the nuclear proportions and observed a notable reduction in the association signals, with 145 probes not reaching epigenome-wide significance. After correction, the top 200 significant DMCs were strongly enriched in active enhancers in trophoblast lineages, whereas 145 non-significant probes were enriched in regions with a quiescent state of chromatin. Our results suggest that future epigenetic studies of PE should focus on functional regulatory sequences.

Aging (Albany NY) 2024; 16:11877-11892. [PMID: 39172111 PMCID: PMC11386924 DOI: 10.18632/aging.206054] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/19/2023] [Accepted: 07/05/2024] [Indexed: 08/23/2024]
Abstract
PURPOSE Autosomal dominant polycystic kidney disease (ADPKD) is the most common cause of end-stage kidney disease. It has been shown that Acyl-CoA thioesterase 13 (ACOT13) level was reduced in renal cystic tissues from ADPKD patients. However, the role of ACOT13 in ADPKD remains largely elusive. METHODS The data in the GSE7869 dataset were acquired from the GEO database to determine ACOT13 level between normal renal cortical tissues and renal cystic tissues. Next, the potential functions of ACOT13 were explored by gene set enrichment analysis (GSEA). Furthermore, ACOT13 level in ADPKD cells (WT9-12) was verified by RT-qPCR. The effects of ACOT13 on WT9-12 cell growth were evaluated using the EdU staining and flow cytometry assays. RESULTS Compared to normal group, ACOT13 mRNA level was obviously reduced in renal cystic tissues and WT9-12 cells. Meanwhile, GSEA results showed that compared to the low ACOT13 expression group, PI3K-Akt and MAPK signaling pathways were inactivated, and PPAR signaling pathway and fatty acid metabolism were activated in high ACOT13 expression group. Furthermore, overexpression of ACOT13 notably reduced WT9-12 cell proliferation and triggered cell cycle arrest. Moreover, ACOT13 overexpression remarkably triggered apoptosis, increased cleaved caspase 3 protein level, reduced ATP production and induced loss of mitochondrial membrane potential in WT9-12 cells, suggesting that ACOT13 overexpression could trigger mitochondrial-related apoptosis in WT9-12 cells. CONCLUSIONS Collectively, our results showed that overexpression of ACOT13 could suppress WT9-12 cell proliferation and trigger mitochondrial-mediated cell apoptosis, suggesting that ACOT13 may exert a protective role in ADPKD.

Abstract
The objective of this study was to determine the predictive value of serum fatty acid binding protein 4 (FABP4) combined with Doppler of the uterine artery in singleton pregnancy at gestational age (GA) 11-13+6 weeks for prediction of preeclampsia. A prospective observational study included singleton pregnant women at GA 11-13+6 weeks and was conducted at the Department of Obstetrics and Gynecology, Faculty of Medicine, Chulalongkorn University, Bangkok, Thailand, between December 2020 and April 2022. Serum FABP4 levels and Doppler of the uterine artery were performed. Pregnancy outcomes were recorded. The predictive values of these combined tests at the optimal cut-off values were determined to predict preeclampsia. A total of 330 participants with 15 cases of preeclampsia (4.5%) and 6 cases of them had preterm preeclampsia (GA < 37 weeks) (1.8%) were analyzed. Women with preeclampsia had significantly higher serum FABP4 levels than normal pregnant women (12.9 ± 6.5 ng/ml vs 10.1 ± 4.8 ng/ml, p = 0.034) but no difference in the mean pulsatility index (PI) of the uterine artery and the presence of an early diastolic notch. When using serum FABP4 levels greater than 1.0 multiple of the median of GA as a cut-off value to predict preeclampsia, combined with abnormal Doppler PI of the uterine artery, the sensitivity, specificity, positive predictive value, and negative predictive value were 73.3%, 47.3%, 6.2%, and 97.4%, respectively. This study demonstrated that serum FABP4 levels combined with Doppler of the uterine artery at GA 11-13+6 weeks were effective in predicting preeclampsia.

Abstract
The pathomechanisms of preeclampsia (PE), a complication of late pregnancy characterized by hypertension and proteinuria, and due to improper placentation, are not well known. Mesenchymal stem cells derived from the amniotic membrane (AMSCs) may play a role in PE pathogenesis as placental homeostasis regulators. PLACenta-specific protein 1 (PLAC1) is a transmembrane antigen involved in trophoblast proliferation that is found to be associated with cancer progression. We studied PLAC1 in human AMSCs obtained from control subjects (n = 4) and PE patients (n = 7), measuring the levels of mRNA expression (RT-PCR) and secreted protein (ELISA on conditioned medium). Lower levels of PLAC1 mRNA expression were observed in PE AMSCs as compared with Caco2 cells (positive controls), but not in non-PE AMSCs. PLAC1 antigen was detectable in conditioned medium obtained from PE AMSCs, whereas it was undetectable in that obtained from non-PE AMSCs. Our data suggest that abnormal shedding of PLAC1 from AMSC plasma membranes, likely by metalloproteinases, may contribute to trophoblast proliferation, supporting its role in the oncogenic theory of PE.

Abstract
Preeclampsia (PE) is a heterogeneous disease for which the current clinical classification system is based on the presence or absence of specific clinical features. PE-associated placentas also show heterogeneous findings on pathologic examination, suggesting that further subclassification is possible. We combined clinical, pathologic, immunohistochemical, and transcriptomic profiling of placentas to develop integrated signatures for multiple subclasses of PE. In total, 303 PE and 1388 nonhypertensive control placentas were included. We found that maternal vascular malperfusion (MVM) in the placenta was associated with preterm PE with severe features and with small-for-gestational-age neonates. Interestingly, PE placentas with either MVM or no histologic pattern of injury showed a linear decrease in proliferative (p63+) cytotrophoblast per villous area with increasing gestational age, similar to placentas obtained from the nonhypertensive patient cohort; however, PE placentas with fetal vascular malperfusion or villitis of unknown etiology lost this phenotype. This is mainly because of cases of fetal vascular malperfusion in placentas of patients with preterm PE and villitis of unknown etiology in placentas of patients with term PE, which are associated with a decrease or increase, respectively, in the cytotrophoblast per villous area. Finally, a transcriptomic analysis identified pathways associated with hypoxia, inflammation, and reduced cell proliferation in PE-MVM placentas and further subclassified this group into extravillous trophoblast-high and extravillous trophoblast-low PE, confirmed using an immunohistochemical analysis of trophoblast lineage-specific markers. Our findings suggest that within specific histopathologic patterns of placental injury, PE can be subclassified based on specific cellular and molecular defects, allowing the identification of pathways that may be targeted for diagnostic and therapeutic purposes.

Abstract
BACKGROUND Trypanosoma cruzi crosses the placental barrier and produces the congenital transmission of Chagas disease (CD). Structural alterations of the chorionic villi by this parasite have been described in vitro, but little is known about trophoblast turnover in placentas from women with CD. OBJECTIVE To analyze the proliferation and fusion processes in placentas from women with CD. METHODS Archived human term placenta paraffin-embedded blocks were used, from women with CD (CDP), and no pathology (NP). Immunohistochemistry tests were performed for Ki67 to calculate the proliferation index (PI) of cytotrophoblast (CTB) and Syncytin-1, a fusion marker of syncytiotrophoblast (STB). Hematoxylin/Eosin stained sections were employed to analyze STB percentages, STB detachment areas and syncytial knots quantity. Non parametric Student's t-tests were performed (p < 0.05). RESULTS Syncytial knots and STB detachment significantly increased in placental villi from the CDP group. STB percentage was significantly lower in the CDP group as well as the PI and Syncytin-1 expression significantly decreased in these placentas, compared with control (NP). CONCLUSION Dynamic of trophoblast turnover is altered in placentas from women with CD. These changes may lead into a gap in the placental barrier possibly allowing the parasite entry into the chorionic villi.

Wang X, Zhang J, Ji J. IL‑1β‑induced pentraxin 3 inhibits the proliferation, invasion and cell cycle of trophoblasts in preeclampsia and is suppressed by IL‑1β antagonists. Mol Med Rep 2022; 25:115.

Abstract
Pentraxin 3 (PTX3), a member of the c‑reactive protein family, is a long pentraxin protein and a pro‑inflammatory marker. However, the role of PTX3 in preeclampsia (PE) remains to be elucidated. Thus, the present study aimed to investigate the biological role and mechanisms underlying PTX3 in PE. In the present study, PTX3 was overexpressed in trophoblasts and the subsequent changes in cell proliferation, cycle distribution and invasion were observed using Cell Counting Kit‑8, flow cytometry and Transwell assays, respectively. Moreover, the expression levels of MMP2 and MMP9, proteins associated with the development of PE, were detected using reverse transcription‑quantitative PCR and western blot analysis. Following treatment with interleukin (IL)‑1β, the expression levels of PTX3 were measured. Furthermore, subsequent changes in cell proliferation, cycle distribution and invasion were investigated following overexpression of PTX3 and treatment with IL‑1 receptor antagonist (IL‑1Ra). Overexpression of PTX3 inhibited the proliferation, cycle and invasion of HTR‑8/SV neo and JEG3 cells. Moreover, treatment with IL‑1β increased the expression of PTX3 in HTR‑8/SV neo and JEG3 cells, which was suppressed following treatment with the IL‑1β antagonist. Following PTX3 overexpression and treatment with IL‑1Ra, the inhibitory effects of PTX3 overexpression alone on the invasion of HTR‑8/SV neo and JEG3 cells were attenuated. In conclusion, these results indicated that IL‑1β could induce PTX3 upregulation, which led to the inhibition of the proliferation, invasion and cell cycle of trophoblasts, thereby promoting the progression of PE.

Abstract
Here, we evaluated the feasibility of non-prodrug PEG-drug conjugates to decrease the accumulation of drugs within the placental tissues. The results showed that PEG was biocompatible with the human placenta with no alteration of the basal rate of proliferation or apoptosis in term placental explants. No significant changes in the released levels of lactate dehydrogenase and the human chorionic gonadotropin were observed after PEG treatment. The cellular uptake studies revealed that conjugating Cy5.5 and haloperidol to PEG significantly reduced (by up to ∼40-fold) their uptake by the placenta. These findings highlight the viability of novel non-prodrug polymer-drug conjugates to avoid the accumulation of drugs within the placenta.

Abstract
Preeclampsia is a pregnancy-specific syndrome characterized by a sudden increase in blood pressure accompanied by proteinuria and/or maternal multi-system damage associated to poor fetal outcome. In early-onset preeclampsia, utero-placental perfusion is altered, causing constant and progressive damage to the syncytiotrophoblast, generating syncytiotrophoblast stress. The latter leads to the detachment and release of syncytiotrophoblast fragments, anti-angiogenic factors and pro-inflammatory molecules into maternal circulation, resulting in the emergence and persistence of the characteristic symptoms of this syndrome during pregnancy. Therefore, understanding the origin and consequences of syncytiotrophoblast stress in preeclampsia is vital to develop new therapeutic alternatives, focused on reducing the burden of this syndrome. In this review, we describe five central characteristics of syncytial stress that should be targeted or prevented in order to reduce preeclampsia symptoms: histological alterations, syncytiotrophoblast damage, antiangiogenic protein export, placental deportation, and altered syncytiotrophoblast turnover. Therapeutic management of these characteristics may improve maternal and fetal outcomes.

Abstract
Pre-eclampsia and fetal growth restriction arise from disorders of placental development and have some shared mechanistic features. Initiation is often rooted in the maldevelopment of a maternal-placental blood supply capable of providing for the growth requirements of the fetus in later pregnancy, without exerting undue stress on maternal body systems. Here, we review normal development of a placental bed with a safe and adequate blood supply and a villous placenta-blood interface from which nutrients and oxygen can be extracted for the growing fetus. We consider disease mechanisms that are intrinsic to the maternal environment, the placenta or the interaction between the two. Systemic signalling from the endocrine placenta targets the maternal endothelium and multiple organs to adjust metabolism for an optimal pregnancy and later lactation. This signalling capacity is skewed when placental damage occurs and can deliver a dangerous pathogenic stimulus. We discuss the placental secretome including glycoproteins, microRNAs and extracellular vesicles as potential biomarkers of disease. Angiomodulatory mediators, currently the only effective biomarkers, are discussed alongside non-invasive imaging approaches to the prediction of disease risk. Identifying the signs of impending pathology early enough to intervene and ameliorate disease in later pregnancy remains a complex and challenging objective.

Abstract
AT-rich interactive domain 1A (ARID1A, as known as BAF250a) is a subunit of human switch/sucrose nonfermentable chromatin remodeling complex with tumour suppressor function. Mutations of Arid1a have been reported in many human cancers and low expression of this protein has been correlated to a poor prognosis outcome in patients affected by some types of cancer. Although there are many studies regarding ARID1A functions in cancer, little is known about its role in regulating cell differentiation and normal tissues homeostasis. Here, we investigate ARID1A expression in normal placental tissues of first and third trimester of gestation and in pathological placental tissues of pregnancy complicated by preeclampsia (PE) and intrauterine growth restriction (IUGR) to evaluate a possible role of this protein in trophoblast differentiation. We found that ARID1A was specifically expressed in villous and extravillous cytotrophoblastic cells in normal placentas whereas syncytiotrophoblast was negative. Interestingly, ARID1A was expressed in both cytotrophoblastic cells and syncytiotrophoblast in placentas affected by PE and PE-IUGR. Moreover, ARID1A was also present in syncitial knots of pathological placentas. The present results indicate that ARID1A is a good marker of poor trophoblast differentiation in these pathologies, because the significant high positive staining in syncytiotrophoblast nuclei may suggest a poor differentiation of this trophoblast layer due to the cytotrophoblast cells fusion with the syncytiotrophoblast overlaying before arresting their cell cycle.

Abstract
Proliferation and metastasis are significantly malignant characteristics of human lung cancer, but the underlying molecular mechanisms are poorly understood. Chromobox 4 (CBX4), a member of the Polycomb group (PcG) family of epigenetic regulatory factors, enhances cellular proliferation and promotes cancer cell migration. However, the effect of CBX4 in the progression of lung cancer is not fully understood. We found that CBX4 is highly expressed in lung tumours compared with adjacent normal tissues. Overexpression of CBX4 significantly promotes cell proliferation and migration in human lung cancer cell lines. The knockdown of CBX4 obviously suppresses the cell growth and migration of human lung cancer cells in vitro. Also, the proliferation and metastasis in vivo are blocked by CBX4 knockdown. Furthermore, CBX4 knockdown effectively arrests cell cycle at the G0/G1 phase through suppressing the expression of CDK2 and Cyclin E and decreases the formation of filopodia through suppressing MMP2, MMP9 and CXCR4. Additionally, CBX4 promotes proliferation and metastasis via regulating the expression of BMI-1 which is a significant regulator of proliferation and migration in lung cancer cells. Taken together, these data suggest that CBX4 is not only a novel prognostic marker but also may be a potential therapeutic target in lung cancer.

Abstract
BACKGROUND This study aimed to clarify the change of the expression of placenta-specific 1 (PLAC1) in the placenta of preeclamptic women and to explore the regulatory effects on thophoblast by PLAC1. METHODS Nineteen women with preeclampsia and 19 with normal pregnancies were recruited, and then we determined the expression of PLAC1 by immunohistochemistry (IHC) and Western blotting. To observe the effect of hypoxia on the expression of PLAC1, trophoblasts were cultured at the normoxia or hypoxia condition. Small interference of ribonucleic acid (siRNA) was used to silence PLAC1. The proliferation, migration and invasion of trophoblasts were evaluated with cell counting kit-8 and transwell analysis, and the apoptosis of trophoblast was evaluated by flow cytometry with FITC and PI staining. RESULTS Placental PLAC1 expression was significantly decreased in severe preeclampsia compared with control (P < .001). The expression of PLAC1 in trophoblasts was significantly decreased after treated with low oxygen concentration (P = .018). PLAC1 siRNA significantly inhibited the proliferation (P < .001), the migration (P < .001) and invasion (P < .001) of trophoblasts, but increased the apoptosis (P = .004 for Swan-71; P = .031 for Jar). CONCLUSIONS The expression of PLAC1 was declined in preeclampsia and this inhibited the function of trophoblast, suggesting PLAC1 may play a role in the development of preeclampsia.

Abstract
OBJECTIVE Trophoblast survival is regulated by cytokines and growth factors. While the pharmacological levels (10-100 ng/mL) of tumor necrosis factor (TNF)- α affect trophoblasts survival in vitro, the effects of the physiological levels (1-10 pg/mL) of TNF-α remain unknown. We investigated the effects of the physiological levels of TNF-α on proliferation and apoptosis of human trophoblast cells by using BeWo cells. Insulin-like growth factor (IGF)-I is also a potent regulator of trophoblast survival and has been known to exert synergistic effects with other hormones. The interaction of IGF-I and TNF-α on BeWo cells survival was also examined. METHODS After incubating BeWo under the presence of TNF-α (10-105 pg/mL) and IGF-I (102 ng/mL), we assessed cell number by WST-1 assay and cell proliferation by BrdU uptake assay and immunocytochemistry with anti-Ki67 antibody. Apoptosis was evaluated by TUNEL assay and caspase-3, 8 activity assays. RESULTS Under the presence of IGF-I, cell number, BrdU uptake, and Ki-67 expression of BeWo were dose-dependently enhanced by low TNF-α (10-102 pg/mL), while no such effects were detected without IGF-I. Higher levels of TNF-α (104-105 pg/mL) showed inhibiting effects on cell number and cell proliferation. The number of TUNEL positive cells were decreased and caspase activities were suppressed by lower levels (10-102 pg/mL) of TNF-α and IGF-I independently. Higher levels of TNF-α (104-105 pg/mL) showed promoting effects on apoptosis irrespective of IGF-I. CONCLUSION The physiological levels of TNF-α and IGF-I had synergetic effects on enhancing cell proliferation and also independently inhibited apoptosis of Bewo cells.

Abstract
Fetal growth and survival is dependent on the elaboration and propinquity of the fetal and maternal circulations within the placenta. Central to this is the formation of the interhaemal membrane, a multi-cellular lamina facilitating exchange of oxygen, nutrients and metabolic waste products between the mother and fetus. In rodents, this cellular barrier contains two transporting layers of syncytiotrophoblast, which are multinucleated cells that form by cell-cell fusion. Previously, we reported the expression of the GPI-linked cell surface protein LY6E by the syncytial layer closest to the maternal sinusoids of the mouse placenta (syncytiotrophoblast layer I). LY6E has since been shown to be a putative receptor for the fusogenic protein responsible for fusion of syncytiotrophoblast layer I, Syncytin A. In this report, we demonstrate that LY6E is essential for the normal fusion of syncytiotrophoblast layer I, and for the proper morphogenesis of both fetal and maternal vasculatures within the placenta. Furthermore, specific inactivation of Ly6e in the epiblast, but not in placenta, is compatible with embryonic development, indicating the embryonic lethality reported for Ly6e−/− embryos is most likely placental in origin.

Abstract
During human pregnancy, cytotrophoblasts (CTBs) play key roles in uterine invasion, vascular remodeling, and anchoring of the feto-placental unit. Due to the challenges associated with studying human placentation in utero, cultured primary villous CTBs are used as a model of the differentiation pathway that leads to invasion of the uterine wall. In vitro, CTBs emulate in vivo cell behaviors, such as migration, aggregation, and substrate penetration. Although some of the molecular features related to these cell behaviors have been described, the underlying mechanisms, at a global level, remain undefined at midgestation. Thus, in this study, we characterized second-trimester CTB differentiation/invasion in vitro, correlating the major morphological transitions with the transcriptional changes that occurred at these steps. After plating on Matrigel as individual cells, CTBs migrated toward each other and formed multicellular aggregates. In parallel, using a microarray approach, we observed differentially expressed (DE) genes across time, which were enriched for numerous functions, including cell migration, vascular remodeling, morphogenesis, cell communication, and inflammatory signaling. DE genes encoded several molecules that we and others previously linked to critical CTB function in vivo, suggesting that the novel DE molecules we discovered played important roles. Immunolocalization confirmed that CTBs in situ gave a signal for two of the most highly expressed genes in vitro. In summary, we characterized, at a global level, the temporal dynamics of primary human CTB gene expression in culture. These data will enable future analyses of various types of in vitro perturbations-for example, modeling disease processes and environmental exposures.

Alteration of serum semaphorin 3B levels in preeclampsia. Clin Chim Acta 2016; 455:60-3. [PMID: 26828533 DOI: 10.1016/j.cca.2016.01.030] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/27/2015] [Revised: 01/26/2016] [Accepted: 01/27/2016] [Indexed: 11/20/2022]
Abstract
BACKGROUND Placental Semaphorin 3B (SEMA 3B) expression has been reported changed in preeclampsia and its possible involvement of in the disease proposed. We clarified the alterations of maternal SEMA 3B level in women suffering preeclampsia and pregnant women at gestational weeks of 16-20 before the onset of preeclampsia. METHODS Serum SEMA 3B concentration was measured with ELISA in preeclamptic women (preeclampsia) and normotensive women (control) in 3rd trimester, and also in pregnant women at gestational weeks of 16-20 who developed preeclampsia or had favorable pregnant outcome. RESULTS Serum SEMA 3B level was significantly increased in preeclampsia compared with control (P<0.001). There was a significant difference in serum SEMA 3B between mild and severe preeclampsia (P=0.04). Women with severe preeclampsia had significant serum SEMA 3B than women with mild preeclampsia. At gestational weeks of 16-20, serum SEMA 3B was significantly higher in women who developed preeclampsia than women who had normal pregnant outcome (P<0.001). CONCLUSIONS Maternal SEMA 3B level increased in preeclampsia before the onset of manifestations, indicating that SEMA 3B plays a role in the pathogenesis of preeclampsia.

Yan Y, Peng H, Wang P, Wang H, Dong M. Increased expression of fatty acid binding protein 4 in preeclamptic Placenta and its relevance to preeclampsia. Placenta 2016; 39:94-100. [PMID: 26992681 DOI: 10.1016/j.placenta.2016.01.014] [Citation(s) in RCA: 24] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/23/2015] [Revised: 01/11/2016] [Accepted: 01/15/2016] [Indexed: 10/22/2022]
Abstract
The aim of this investigation was to determine the expression of fatty acid binding protein 4 (FABP4) in the placenta from women with preeclampsia and normal pregnancy, and to delineate the regulatory effects on thophoblast cell by FABP4. We determined the expression of FABP4 by real-time polymerase chain reaction (PCR) for messenger ribonucleic acid (mRNA) or enzyme-linked immunesorbent assay (ELISA) and Western blotting for protein. Small interference of ribonucleic acid (siRNA) and specific FABP4 inhibitor were used to inhibit FABP4. The proliferation, migration and invasion of trophoblastic cells (Swan-71 and Jar) were evaluated with cell counting kit-8, wound-healing test and transwell analysis respectively. We found the expression of FABP4 was significantly higher in the placenta of preeclamptic women than that of women with normal pregnancy (t = 4.244, P < 0.001 for mRNA; t = 4.536, P < 0.001 for protein). FABP4 siRNA significantly reduced the proliferation of trophoblasts (P < 0.001). The specific inhibition of FABP4 inhibited the proliferation of trophoblasts in a dose-dependent manner (P < 0.001) and the inhibitory effect increased as the concentration of inhibitor increased. FABP4 siRNA and specific inhibitor significantly decreased the migration (P < 0.001) and invasion (P < 0.001) of trophoblasts. We concluded the increase in placental FABP4 expression in preeclampsia may affect the function of trophoblast, and this increase may have a role in the pathogenesis of preeclampsia.
