Abstract
Existing research has confirmed the dysregulation of circular RNA (circRNA) in a wide variety of human diseases. Thus, in this study, we explored the potential mechanism of circRNA_0088196 in preeclampsia (PE). We performed quantitative real-time PCR to examine circRNA_0088196 expression and verified the function of circRNA_0088196 in vitro using CCK-8, TUNEL, flow cytometry, and Western blotting analyses. Additionally, we studied the mechanism using dual-luciferase reporter gene experiments. The results of our research revealed the up-regulation of circRNA_0088196 in PE patients' placentas and Heat Shock 70 kDa Protein 5 (HSPA5)-stimulated trophoblast (HTR-8/SVneo) cells. An investigation of the mechanism also showed that there was a binding between miR-379-5p and circRNA_0088196. Additionally, circRNA_0088196 inhibited HTR-8/SVneo cell proliferation and promoted cell apoptosis via the miR-337-3p/HSPA5 axis, thereby facilitating PE. In vivo experiments indicated that circRNA_0088196 regulated HTR-8/SVneo cell production through miR-379-5p. Overall, the findings of this study illustrate that circRNA_0088196 interference promotes cell apoptosis and inhibits HTR-8/SVneo proliferation via the miR-379-5p/HSPA5 axis, thereby accelerating the development of PE.

Abstract
Ferroptosis is the oxidative death of cells attributed to an imbalance in intracellular lipid reactive oxygen species metabolism, a reduction in cell antioxidant capacity, and an accumulation of membrane lipid peroxides. Trophoblast cells are a group of cells susceptible to ferroptosis. The ferroptosis of trophoblast cells has a major effect on the development of preeclampsia (PE), although the impact of ferroptosis-related genes (FRGs) on PE has not been well characterized. This study obtained PE-related information from the Gene Expression Omnibus database and FRGs from the FerrDb ferroptosis database. Seventeen PE-related differentially expressed ferroptosis-related genes (DE-FRGs) that were closely associated with cellular regulation and immune response were obtained. According to the results of a subsequent functional enrichment analysis, it was found that the above marker genes may impact PE by regulating immune response, amino acid metabolism, the cell cycle, and multiple pathways correlated with PE pathogenesis. Subsequently, we used LASSO and support vector machine recursive feature elimination algorithms to help identify GOT1, CFL1, FZD7, VDR, PARP6, TMSB4X, VCP, and ENO3 as marker genes from the 17 obtained genes. According to the results of single-sample gene set enrichment analysis (ssGSEA), the immune microenvironment of PE changed, possibly due to the GOT1 and TMSB4X genes. Furthermore, 23 drugs targeting one marker gene were determined. A constructed ceRNA network revealed a complicated regulatory link based on the eight marker genes. In this study, diagnostic potency was developed, and insight into the mechanism of PE was provided. In-depth research should be conducted before clinical application to evaluate the diagnostic value of DE-FRGs in PE.

Placenta 2024; 147:1-11. [PMID: 38277999 DOI: 10.1016/j.placenta.2024.01.008] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/21/2023] [Revised: 01/15/2024] [Accepted: 01/18/2024] [Indexed: 01/28/2024]
Abstract
INTRODUCTION Preeclampsia (PE) is a pregnancy complication that encompasses various pathogenic mechanisms. Shallow implantation of the placenta due to abnormal trophoblast behavior is considered an important mechanism underlying PE; however, its exact etiology remains unclear. METHODS The expression of OLFML3 in the placenta and important clinical indicators were performed, followed by a correlation analysis. The effect of OLFML3 on the behavior of HTR-8/SVneo cells was examined, and the downstream molecular mechanisms of OLFML3 were investigated in HTR-8/SVneo cells. Additionally, a rat model of PE was generated by adenovirus injection via the tail vein to verify the role of OLFML3. RESULTS OLFML3 is highly expressed in both syncytiotrophoblasts and cytotrophoblasts and deregulated in preeclamptic placentas. OLFML3 overexpression in HTR-8/SVneo cells promoted cell proliferation, migration, invasion, and impeded apoptosis, and triggered phosphorylation on ser473 of AKT. Conversely, OLFML3 knockdown exerted opposite effects. Furthermore, OLFML3 overexpression ameliorates CoCl2-induced apoptosis of HTR-8/SVneo cells. In a rat model, OLFML3 overexpression alleviates PE-associated maternal symptoms, leading to lower blood pressure, less severe proteinuria, improved fetal growth restriction, as well as upregulation of P-AKT and downregulation of Cleaved caspase3 and Bax. DISCUSSION OLFML3 may alleviate PE development by inhibiting extravillous trophoblast cell apoptosis through the PI3K/AKT pathway. Our findings indicated that OLFML3 may provide a possible therapeutic target for PE.

Autoimmunity 2023; 56:2281223.

Abstract
Airway remodeling is an important pathologic factor in the progression of asthma. Abnormal proliferation and migration of airway smooth muscle cells (ASMCs) are important pathologic mechanisms in severe asthma. In the current study, claudin-1 (CLDN1) was identified as an asthma-related gene and was upregulated in ASMCs stimulated with platelet-derived growth factor BB (PDGF-BB). Cell counting kit-8 and EdU assays were used to evaluate cell proliferation, and transwell assay was carried out to analyze cell migration and invasion. The levels of inflammatory factors were detected using enzyme-linked immunosorbent assay. The results showed that CLDN1 knockdown inhibited the proliferation, migration, invasion, and inflammation of ASMCs treated with PDGF-BB, whereas overexpression of CLDN1 exhibited the opposite effects. Protein-protein interaction assay and co-immunoprecipitation revealed that CLDN1 directly interacted with matrix metalloproteinase 14 (MMP14). CLDN1 positively regulated MMP14 expression in asthma, and MMP14 overexpression reversed cell proliferation, migration, invasion, and inflammation induced by silenced CLDN1. Taken together, CLDN1 promotes PDGF-BB-induced cell proliferation, migration, invasion, and inflammatory responses of ASMCs by upregulating MMP14 expression, suggesting a potential role for CLDN1 in airway remodeling in asthma.

Abstract
INTRODUCTION To investigate the role of claudin-1 (CLDN1) in trophoblast invasion and endovascular trophoblast (enEVT) differentiation in early-onset preeclampsia (EOPE). METHODS The expression and localization of CLDN1 in normal (n = 18) and EOPE (n = 20) placental tissues were detected by immunohistochemical (IHC) staining, quantitative real-time polymerase chain reaction (qRT‒PCR) and Western blotting. Next, invasion, migration and tube formation assays were performed to explore the involvement of CLDN1 in trophoblast invasion and enEVT differentiation in trophoblast cell lines (HTR8/SVneo). Then, invasion and enEVT markers were analyzed via Western blotting and qRT‒PCR, respectively. Finally, we established an EOPE mouse model to detect the Cldn1 protein level. RESULTS CLDN1 expression was significantly decreased in EOPE placental tissues. Knockdown of CLDN1 suppressed HTR8/SVneo cell invasion, migration and the ability to penetrate the endothelial tube. Conversely, overexpression of CLDN1 promoted trophoblast invasion and the ability to invade the endothelial tube. Inhibition of CLDN1 decreased the protein expression of VIM and SNAIL along with downregulating IL1B and PECAM1 mRNA levels, while overexpression of CLDN1 gave the opposite results. In the EOPE mouse model, we found a decrease in Cldn1 expression in EOPE mouse placentas. DISCUSSION These results suggest that the downregulation of CLDN1 in trophoblast cells is involved in the pathogenesis of early-onset preeclampsia by affecting trophoblast invasion and enEVT differentiation.

Abstract
Identification of ischemia-reperfusion injury (I/R)-associated genes is essential for exploring I/R novel mechanisms. Previously, we screened differentially expressed genes in renal I/R mouse models and found that Tax1 binding protein 3 (Tip1) and baculoviral IAP repeat containing 3 (Birc3) are two upregulated genes in I/R. In the present study, we analyzed the expression of Tip1 and Birc3 in I/R models. We found that the expression of Tip1 and Birc3 was upregulated in I/R-treated mice, whereas Tip1 was downregulated and Birc3 was upregulated in oxygen-glucose deprivation/reoxygenation (OGD/R) in vitro models. By inhibiting Birc3 with AT-406 in I/R-treated mice, we observed that the serum creatinine or blood urea nitrogen did not vary. However, inhibition of Birc3 enhanced apoptosis of kidney tissues induced by I/R treatment. Consistently, we found that inhibition of Birc3 also increased the apoptosis rate in tubular epithelial cells induced by OGD/R. These data demonstrated that Tip1 and Birc3 were upregulated in I/R injury. The upregulation of Birc3 may protect against renal I/R injury.

Abstract
Prostaglandins participate in maternal recognition of pregnancy, implantation and maintenance of gestation. Prostaglandin transporter (PGT), as a candidate molecule of prostaglandin carriers, might be involved in the pathogenesis of preeclampsia. In preeclampsia (PE) patients' placental tissue, we identified PGT by RNA sequencing, measured its expression pattern by quantitative real-time PCR and Western blot. PGT was found to be upregulated in preeclamptic placental tissue. The expression pattern of PGT in PE was double confirmed by eight Gene Expression Omnibus (GEO) databases. In abortion tissues at 6-8 weeks, we then observed the cellular location of PGT by Immunofluorescence technique (IF) and found PGT located in trophoblast cell of the placenta of early pregnancy. In vitro studies revealed that forced expression of PGT in HTR8/Sveno cell inhibited its apoptosis, but promoted its proliferation by activating Erk signaling. In vivo study, we used reduced uterine perfusion pressure (RUPP) rat model and L-NAME-induced preeclampsia-like rats to study the possible role of PGT in preeclampsia. And PGT was found to be upregulated in both preeclampsia rat models by Immunohistochemical (IHC) staining. Newly identified PGT plays an important role in trophoblast proliferation via Erk signaling, providing new insights for understanding the pathogenesis of PE.
