Abstract
Preeclampsia (PE) is a serious pregnancy complication, and its primary clinical manifestations are gestational hypertension and proteinuria. Trophoblasts are responsible for the basic functions of the placenta during placental development; recent studies have revealed that placental "shallow implantation" caused by the decreased invasiveness of placental trophoblasts plays a crucial role in PE pathogenesis. The interaction between the cells and the extracellular matrix (ECM) plays a crucial role in trophoblast proliferation, differentiation, and invasion. Abnormal ECM function can result in insufficient migration and invasion of placental trophoblasts, thus participating in PE. This article summarizes the recent studies on the involvement of ECM components, including small leucine-rich proteoglycans, syndecans, glypicans, laminins, fibronectin, collagen, and hyaluronic acid, in the development of PE. ECM plays various roles in PE development, most notably by controlling the activities of trophoblasts. The ECM is structurally stable and can serve as a biological diagnostic marker and therapeutic target for PE.

Abstract
OBJECTIVE This study aimed to collect, organize, and conduct a meta-analysis of the literature on the expression of silent information regulator two homolog 1 (SIRT1) in the placental tissue and plasma of patients with pre-eclampsia. METHODS The enrolled patients were divided into two groups: the pre-eclampsia group and the healthy group. This study summarized and analyzed the demographic characteristics of the two groups, including pregnancy age, gestational weeks, parity, gravidity, blood pressure, Body Mass Index, newborn weight, placental weight, and SIRT1 expression in placental tissue and maternal plasma. RESULTS Eleven studies were included in this research, with 586 cases in the pre-eclampsia group and 479 cases in the control group. Three research studies are reporting immunohistochemistry tests, among which the pre-eclampsia group had a positivity rate of 30.24% (62/205), while the control group had 58.02% (76/131); the two groups have a significant difference (p < 0.05). Two research studies reported the results of ELISA tests, with 107 cases in the pre-eclampsia group and 125 cases in the control group. A comparison of the SIRT1 test results showed a statistically significant difference between the two groups (p < 0.05). Pre-eclampsia group patients had lower gestational weeks, newborn birth weight, and placental weight compared to the healthy control group (all p < 0.05). However, systolic and diastolic blood pressures were higher in the pre-eclampsia group than in the control group (p < 0.05). CONCLUSION SIRT1 expression is downregulated in pre-eclampsia patients' plasma and placental tissue. Further research is needed to validate this conclusion.

Abstract
The aim of this study was to investigate the role of ubiquitin-specific peptidase 8 (USP8) in human trophoblast cells and its molecular mechanism. Based on the GSE30186 dataset, USP8 was identified as a downregulated gene in pre-eclampsia (PE). Analysis of clinical samples also revealed that USP8 expression at both the mRNA and protein levels in placental tissue from patients with PE was significantly lower than that from healthy pregnant women. Plate clone formation, scratch-wound healing, Transwell, tubule formation, and western blot assays collectively revealed that USP8 overexpression promoted the proliferation, migration, invasion, and pro-angiogenesis function of trophoblast cells, while USP8 knockdown induced the opposite effects. Bioinformatics analysis and luciferase reporter assay results indicated that the 3' untranslated region of USP8 was targeted by miR-874-3p. USP8 expression in the placental tissue of patients with PE was significantly lower than that of healthy pregnant women. USP8 actively regulated the growth and invasion of human trophoblast cells and stabilized the epithelial sodium channel (ENaC) on the cell membrane. MiR-874 targeted USP8 in the trophoblast cells and upregulation of miR-874-3p resulted in a decrease in the proliferation, migration, invasion, and pro-angiogenesis ability of trophoblast cells. These results indicate that USP8 can reverse the above mentioned negative effects of miR-874-3p on trophoblast cells. USP8 targeted by miR-874-3p facilitates the invasion of trophoblastic cells by stabilizing the expression of the ENaC, which may be a possible therapeutic target for PE.

Abstract
Trophoblast stem (TS) cells were first isolated from the mouse placenta; however, little is known about their maintenance and niche in vivo. TS cells, like other stem cells, have a unique microenvironment in which the extracellular matrix (ECM) is a component. Placental pathology is associated with ECM change. However, how these changes and the individual ECM components impact the maintenance or differentiation of TS cells has not been established. This study identified which ECM component(s) maintain the greatest expression of markers associated with undifferentiated mouse trophoblast stem (mTS) cells and which alter the profile of markers of differentiation based on mRNA analysis. mTS cells cultured on individual ECM components and subsequent quantitative polymerase chain reaction analysis revealed that laminin promoted the expression of markers associated with undifferentiated TS cells, fibronectin promoted gene expression associated with syncytiotrophoblast (SynT) layer II cells, and collagen IV promoted the expression of genes associated with differentiated trophoblast. To investigate whether pathological placental ECM influenced the expression of genes associated with different trophoblast subtypes, the mouse model of streptozotocin (STZ)-induced pancreatic β cell ablation and diabetes was used. Female mice administered STZ (blood glucose ≥300 mg/dL) or control (blood glucose ≤150 mg/dL) were mated. Placental pathology at embryonic day (E)14.5 was confirmed with reduced fetal blood space area, reduced expression of the pericyte marker αSMA, and decreased expression of ECM proteins. mTS cells cultured on ECM isolated from STZ placenta were associated with reduced expression of undifferentiated mTS markers and increased expression of genes associated with terminally differentiated trophoblast [Gcm-1 and SynA (SynT) and junctional zone Tpbpa and Prl2c2]. Altogether, these results support the value of using ECM isolated from the placenta as a tool for understanding trophoblast contribution to placental pathology.

Abstract
Passive transfer of antithyroid antibodies in mice leads to reproductive disorders. The purpose was to assess the placental tissue of experimental animals under the influence of the circulating thyroperoxidase antibodies. We performed an immunohistochemical examination of murine placentae after a passive transfer of thyroperoxidase antibodies. Placentae of mice that passively transferred IgG from healthy donors were used as control samples. For histological examination, 30 placental samples were selected from mice from the anti-TPO group and 40 placental samples were taken from mice from the IgG group. Immunostaining for VEGFR1, THBS 1, Laminin, CD31, CD34, FGF-β, CD56, CD14, TNF-α, kisspeptin, MCL 1, and Annexin V was performed. There is a significant decrease in the relative area of the expression of VEGFR1 (23.42 ± 0.85 vs. 33.44 ± 0.35, P < 0.01), thrombospondin 1 (31.29 ± 0.83 vs. 34.51 ± 0.75, P < 0.01), CD14 (25.80 ± 0.57 vs. 32.07 ± 0.36, P < .01), CD56 (30.08 ± 0.90 vs. 34.92 ± 0.15, P < 0.01), kisspeptin (25.94 ± 0.47 vs. 31.27 ± 0.57, P < 0.01), MCL 1 (29.24 ± 1.06 vs. 38.57 ± 0.79, P < 0.01) in the labyrinth zone of the placentae of mice from the anti-TPO group compared with control group. A significant increase in the relative expression of laminin and FGF-β was noted in the group of mice to which antibodies to thyroperoxidase were transferred, compared with the control group (36.73 ± 1.38 vs. 29.83 ± 0.94, P < 0.01 and 23.26 ± 0.61 vs. 16.38 ± 1.01, P < 0.01respectively). Our study exposed an imbalance of pro- and anti-angiogenic factors, decreased representation of placental macrophages and NK cells, abnormal trophoblast invasion processes, and insufficient expression of antiapoptotic factors in the placentae of mice in which anti-TPO antibodies were passively transferred.

J Obstet Gynaecol Res 2023; 49:548-559.

Abstract
BACKGROUND Placenta accreta spectrum (PAS) is an ongoing major iatrogenic public health challenge with devastating obstetric complications, but its underlying molecular pathogenesis remains poorly illuminated. LAMC2 is reported to regulate tumor cells proliferation and invasion, yet has not been explored in placenta trophoblast cells. This study investigated LAMC2 expression and its contribution in the etiology of PAS. METHODS Quantitative polymerase chain reaction, western blot, and immunohistochemistry were performed to detect the expression of LAMC2 in placentas. Cell proliferation, invasion, migration, and apoptosis were monitored by CCK8 assay, wound healing assay, transwell invasion assay, and flow cytometry assay. Western blot was conducted to confirm the pertinent proteins level of PI3K/Akt/MMP2/9 pathway in HTR8/SVneo cells. RESULTS LAMC2 was predominantly expressed in placental villous syncytiotrophoblasts and cytotrophoblasts. LAMC2 mRNA and protein expression were substantially upregulated in placental tissues with PAS compared to those with pernicious placenta previa without PAS. LAMC2 overexpression eminently boosted HTR8/SVneo cells proliferation, invasion, and migration, but inhibited apoptosis, accompanied by elevated protein expression of MMP2, MMP9, and phosphorylated Akt (pAkt). Knockdown of LAMC2 yielded the converse results. Additionally, when treated with LY294002, the effects of LAMC2 overexpression on proliferation, migration, invasion, and apoptosis of HTR8/SVneo cells were abolished and concomitantly the elevated pAkt, MMP2, and MMP9 proteins induced by LAMC2 overexpression were eliminated. CONCLUSION Our study highlighted the involvement of LAMC2 in the pathogenesis of PAS by activating the PI3K/Akt/MMP2/9 signaling pathway to stimulate trophoblast over-invasion. These findings provide a new target for the diagnosis and disease stratification of PAS.

Abstract
The implantation and placental development processes are regulated with cell adhesion molecules and remodeling of the maternal endometrium's extracellular matrices (ECM) and fetal chorion. This study aimed to investigate the distribution and localization of some classical cadherins (E-, N-, and P-cadherins) and extracellular matrix components collagen type 5α1, fibronectin, and laminin in the cow placentomes during pregnancy using immunohistochemical and Western blotting analyses. The study results confirmed the expression of E- and P-cadherins, collagen type Vα1 (COLVα1), fibronectin, and laminin in the cow placentomes, but not N-cadherin. Throughout the pregnancy, E- and P- cadherins, COLVα1, and laminin were localized in the luminal and glandular epithelium of the inter-caruncular endometrium, caruncular epithelium, and the uninucleate (UNCs) and binucleate trophoblast giant cells (BNCs/TGCs). E- cadherin immunoreactivity in the first pregnancy period was strong in the UNCs while moderate in the BNCs/TGCs. However, it was weak in both trophoblast in the second and third pregnancy periods. In the fetal trophoblasts, P- cadherin and laminin immunostainings were more intense in the BNCs/TGCs than UNCs. The fetal and maternal stromal cells were also positive for P- cadherin, COLVα1, fibronectin, and laminin. The immunostaining intensity of COLVα1 and fibronectin in the stromal extracellular matrix of the placentomes decreased as the pregnancy progressed. The endothelia of fetal and maternal vessels were positive for all proteins. The presence and distinct localization of cadherins and ECM proteins in the cow placentome components support the role of these molecules in regulating placental cell growth, migration, and matrix production during pregnancy.

Abstract
Endothelial cell dysfunction is an essential pathophysiological feature of preeclampsia (PE). It has been reported that cathepsin C is upregulated in the maternal vascular endothelium of PE patients. The excessive activation of p38 MAPK leads to various diseases, including PE. NF-κB pathway can promote uteroplacental dysfunction, endothelial stress and development of PE. Moreover, it has been verified that cathepsin C can activate p38 MAPK/NF-κB pathway. In the present work, hypoxia/reoxygenation (H/R) injury model of HUVECs was established to discuss the biological functions of cathepsin C in endothelial cell dysfunction and to elucidate the underlying molecular mechanism. The correlation between cathepsin C and p38 MAPK/NF-κB pathway in H/R-stimulated HUVECs as well as the effects of cathepsin C and p38 MAPK/NF-κB pathway on viability, apoptosis, invasion, in vitro angiogenesis of HUVECs and oxidative stress were assessed. The results revealed that H/R injury elevated cathepsin C expression and activated p38 MAPK/NF-κB pathway in HUVECs and cathepsin C knockdown inhibited the activity of p38 MAPK/NF-κB pathway in H/R-stimulated HUVECs. Downregulation of cathepsin C improved viability, inhibited apoptosis and enhanced invasion of H/R-stimulated HUVECs. In addition, downregulation of cathepsin C alleviated oxidative stress and induced stronger HUVEC angiogenesis in vitro. Furthermore, the protective effects of cathepsin C knockdown against endothelial cell dysfunction were reversed by p38 MAPK activator anisomycin. In other words, downregulation of cathepsin C could improve HUVEC viability and enhance anti-apoptotic capacity, anti-oxidative capability, invasive ability, as well as angiogenic potential of H/R-stimulated HUVECs by repressing p38 MAPK/NF-κB pathway.
