Abstract
INTRODUCTION Preeclampsia (PE) is a serious pregnancy-related complication caused by high blood pressure in pregnant women. The severe form has more devastating effects. According to the growing evidence, the placenta is a crucial component in the pathogenesis of PE, and eliminating it will alleviate symptoms. METHODS GEO's severe preeclampsia placenta microarray datasets; GSE147776, GSE66273, GSE102897, and GSE10588, were chosen to identify differentially expressed genes (DEGs) in different biological pathways. The analysis of hub genes and related non-coding RNAs was done as well. RESULTS A total of 347 DEGs with adj p-value <0.05 and ǀlog2FoldChangeǀ> 0.5 were discovered between severe PEs and healthy pregnancies, including 204 over-expressed genes and 143 under-expressed genes. The MCC method identified ISG15, IFI44L, MX2, OAS2, MX1, FN1, LDHA, ITGB3, TKT, HK2 genes as the top ten hub genes. Interactions between hub genes and noncoding RNAs were also conducted. The most enriched pathways were as follows; HIF-1 signaling pathway; Pathways in cancer; Alanine, aspartate and glutamate metabolism; Arginine biosynthesis; Human papillomavirus infection; Glycolysis/Gluconeogenesis; Central carbon metabolism in cancer; Valine, leucine and isoleucine degradation; Cysteine and methionine metabolism; and Galactose metabolism. DISCUSSION This is a secondary data analysis conducted on severe preeclampsia placenta to identify differentially expressed genes, biological pathways, hub-genes, and related noncoding RNAs. Functional studies are crucial to understanding the precise role of these genes in the pathogenesis of PE. Also, accepting a gene as a diagnostic or prognostic marker for early diagnosis and management of PE requires multiple lines of evidence.

[PMID: 39271534 DOI: 10.1007/s13258-024-01563-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/01/2024] [Accepted: 08/24/2024] [Indexed: 09/15/2024]
Abstract
BACKGROUND Pre-eclampsia (PE) is characterized by the onset of hypertension and proteinuria during pregnancy. Here, we aimed to explore the functions of nuclear receptor-interacting protein 1 (NRIP1) in PE mice and human placental JEG-3 cells. We evaluated its effects on JEG-3 cell proliferation, apoptosis, invasion, and inflammatory response and regulation of Wnt/β-catenin pathway. METHODS NRIP1 levels in human serum and placental tissues, JEG-3 cells, and mouse models were assessed via quantitative reverse transcription-polymerase chain reaction (qRT-PCR) and western blotting. JEG-3 cell growth, apoptosis, migration, and invasion were evaluated via 5-ethynyl-2'-deoxyuridine, flow cytometry, and transwell assays. Levels of the inflammatory factors, matrix metalloproteinase (MMP)-2, tumor necrosis factor (TNF)-α, and interleukin (IL)-6, were determined via enzyme-linked immunosorbent assay. Wnt/β-catenin pathway was assessed via western blotting and qRT-PCR. Systolic blood pressure and proteinuria were measured using the non-invasive tail cuff method and Coomassie brilliant blue assay, respectively. TdT-mediated dUTP nick-end labeling assay was used to assess cell apoptosis in the placental tissues of PE mice. RESULTS NRIP1 levels were upregulated in the serum and placental tissues of patients with PE. In vitro experiments revealed that NRIP1-small interfering RNA (siRNA) increased the cell viability, migration, and invasion and reduced the cell apoptosis compared to the control siRNA. Moreover, NRIP1-siRNA activated the Wnt/β-catenin signaling pathway, as indicated by the increased Wnt3a, β-catenin, p-glycogen synthase kinase-3β, c-Myc, and cyclin D1 levels. Levels of the inflammatory factors, IL-6, TNF-α, and MMP-2, were decreased in the NRIP1-siRNA-treated group. Notably, NRIP1 downregulation improved the PE-like symptoms, inhibited the inflammatory responses, and reduced apoptosis in PE mice. CONCLUSION This study revealed the crucial roles of NRIP1 in PE. Our findings revealed that NRIP1 downregulation relieved PE symptoms by inhibiting cell proliferation, migration, and invasion via the Wnt/β-catenin pathway, thus providing a novel candidate for PE treatment.

Abstract
The functions and molecular mechanisms of long noncoding RNA (lncRNA) in reproduction have been widely studied at present. However, lncRNA regulating hormone synthesis in ovarian follicular granulosa cells has not been sufficiently studied. Our previous research demonstrated that lncRNA Gm2044 could promote estradiol synthesis in follicular granulosa cells. In this study, we identified 21 binding proteins of lncRNA Gm2044 in ovarian follicles using comprehensive identification of RNA-binding proteins by mass spectrometry (ChIRP-MS). RNA immunoprecipitation (RNA IP) and reverse transcription PCR (RT-PCR) confirmed that lncRNA Gm2044 can interact with eukaryotic translation elongation factor 2 (EEF2) protein. Furthermore, we constructed lncRNA Gm2044 knockout mice using the CRISPR/Cas9 method. Although the follicular development and fertility of female lncRNA Gm2044 knockout mice were not affected, the serum estradiol concentration in female lncRNA Gm2044 knockout mice significantly decreased. Western blotting and ELISA revealed that lncRNA Gm2044 may promote the binding of EEF2 to Nr5a1 mRNA and then enhance the Nr5a1 mRNA translation, and the upregulated NR5A1 protein can strengthen estradiol synthesis. To determine the potential signaling pathway of lncRNA Gm2044 regulating estradiol synthesis, transcriptome sequencing was performed for ovaries of adult lncRNA Gm2044 knockout mice, which identified 565 significant up-regulated genes and 303 significant down-regulated genes, which were then analyzed with Gene Ontology (GO) and the Kyoto Encyclopedia of Genes and Genomes (KEGG) and validated by molecular experiments. Understanding how lncRNA Gm2044/EEF2 protein regulates estradiol synthesis will help treat estrogen-related reproductive diseases.

Arch Biochem Biophys 2023; 737:109522. [PMID: 36657605 DOI: 10.1016/j.abb.2023.109522] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/30/2022] [Revised: 01/06/2023] [Accepted: 01/15/2023] [Indexed: 01/17/2023]
Abstract
OBJECTIVE Preeclampsia (PE) is a pregnancy-specific syndrome. Ligustrazine (LSZ) is involved in hypoxia/reoxygenation (H/R)-treated trophoblast cell regulation, but its mechanism remains elusive. This study explored the mechanism of LSZ in H/R-treated trophoblast cells to provide a theoretical basis for the new treatment method development for PE. METHODS H/R HTR8/SVneo cell model was established for PE simulation to some extent. Trophoblast cell proliferation, apoptosis rate, migration, and invasion were detected by MTT assay, flow cytometry, scratch test, and Transwell assay. miR-27a-3p expression in trophoblast cells was detected by RT-qPCR. Binding sites between miR-27a-3p and ATF3 were predicted using Starbase and verified by dual-luciferase reporter assay. Activating transcription factor 3 (ATF3), β-catenin, Cyclin D1, and c-Myc protein levels were examined using Western blot. After LSZ treatment, H/R-induced HTR8/SVneo cells were delivered with miR-27a-3p mimic or ATF3 siRNA to verify their roles in HTR8/SVneo cells. RESULTS LSZ facilitated the proliferation, migration, and invasion of trophoblast cells and inhibited apoptosis. miR-27a-3p was elevated in H/R-induced HTR8/SVneo cells and miR-27a-3p overexpression annulled the effect of LSZ on trophoblast cells. miR-27a-3p targeted ATF3. ATF3 silencing averted the property of LSZ on trophoblast cells. Wnt/β-catenin pathway-related proteins were repressed in H/R-induced HTR8/SVneo cells, and LSZ activated the Wnt/β-catenin pathway by promoting ATF3 expression. CONCLUSION LSZ mediated the Wnt pathway by regulating the miR-27a-3p/ATF3 axis, thus promoting the proliferation and migration of trophoblast cells. The protective mechanism of LSZ showed the potential application value in the treatment of PE.

[PMID: 35140505 PMCID: PMC8818964 DOI: 10.2147/ijgm.s348175] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/24/2021] [Accepted: 01/17/2022] [Indexed: 11/23/2022] Open
Abstract
Objective Preeclampsia (PE) is a pregnancy-specific multisystem disease as well as an important cause of maternal and perinatal death. This study aimed to analyze the placental transcriptional data and clinical information of PE patients available in the published database and predict the target genes for prevention of PE. Methods The clinical information and corresponding RNA data of PE patients were downloaded from the GEO database. Cluster analysis was performed to examine the correlation between different genotyping genes and clinical manifestations. Then, bioinformatic approaches including GO, KEGG, WGCNA, and GSEA were employed to functionally characterize candidate target genes involved in pathogenesis of PE. Results Two PE datasets GSE60438 and GSE75010 were obtained and combined, thereby providing the data of 205 samples in total (100 non-PE and 105 PE samples). After eliminating the batch effect, we grouped and analyzed the integrated data, and further performed GSEA analysis. It was found that the genes in group 1 and group 2 were different from those in normal samples. Moreover, WGCNA analysis revealed that genes in group 1 were up-regulated in turquoise module, including SASH1, PIK3CB and FLT-1, while genes in group 2 were up-regulated in the blue and brown modules. We further conducted GO and KEGG pathway enrichment analyses and found that the differential genes in turquoise module were mainly involved in biological processes such as small molecular catabolic process, while being highly enriched in pathways, including MAPK signaling pathway and Rap1 signaling pathway. Conclusion FLT-1 was conventionally used to predict PE risk, and sFLT-1 could also be used as an indicator to evaluate PE treatment effect. As a candidate biomarker for predicting PE, SASH1 may participate in proliferation, migration, invasion and epithelial mesenchymal transformation of human trophoblast cells by regulating MAPK pathway and Rap1 signaling pathway, thus affecting the progression of PE. The mechanism allowing PIK3CB to regulate PE development was not clear, while the gene could be another candidate biomarker for PE risk prediction. This is an exploratory study and our findings were still required verification in further studies.
