Abstract
Recurrent spontaneous abortion (RSA) is defined as two or more pregnancy loss, which affects approximately 1-2 % of women's fertility. The etiology of RSA has not yet been fully revealed, which poses a great problem for clinical treatment. Post- translational modifications(PTMs) are chemical modifications that play a crucial role in the functional proteome. A considerable number of published studies have shown the relationship between post-translational modifications of various proteins and RSA. The study of PTMs contributes to elucidating the role of modified proteins in the pathogenesis of RSA, as well as the design of more effective diagnostic/prognostic tools and more targeted treatments. Most reviews in the field of RSA have only focused on RNA epigenomics research. The present review reports the latest research developments of PTMs related to RSA, such as glycosylation, phosphorylation, Methylation, Acetylation, Ubiquitination, etc.

Metastasis-associated lung adenocarcinoma transcript 1 induces methyl-CpG-binding domain protein 4 in mice with recurrent spontaneous abortion caused by anti-phospholipid antibody positivity. Placenta 2023; 137:38-48. [PMID: 37068447 DOI: 10.1016/j.placenta.2023.04.008] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/10/2022] [Revised: 02/27/2023] [Accepted: 04/07/2023] [Indexed: 04/19/2023]
Abstract
INTRODUCTION Antiphospholipid syndrome is an autoimmune disease characterized by pregnancy-related morbidity, related to persistent positivity of antiphospholipid antibodies (APL). One of the characteristics of pregnancy-related morbidity in patients with antiphospholipid syndrome is recurrent spontaneous abortion (RSA). This study aimed to examine the mechanism through which metastasis-associated lung adenocarcinoma transcript 1 (MALAT1) regulates methyl-CpG-binding domain protein 4 (MBD4) expression in APL-positive RSA. METHODS Clinical samples were subjected to microarray analysis to filter differentially expressed genes. RSA mice with APL positivity were generated, followed by adenoviral vector injection to artificially upregulate MALAT1. The effects of MALAT1 on the biological behavior of trophoblast cells were assessed. The downstream mechanism of MALAT1 was analyzed using subcellular fractionation and bioinformatics prediction, and the relationship between MALAT1 and CREB binding protein (CREBBP) or MBD4 was investigated in trophoblast cells. RESULTS MALAT1 was downregulated in APL-positive RSA patients. MALAT1 was predominantly localized in the nucleus and recruited CREBBP to mediate the MBD4 transcription. In the APL-positive RSA mice overexpressing MALAT1, the expression of soluble Fms-related tyrosine kinase 1 and anticardiolipin antibody and the embryonic resorption rate were decreased, indicating that MALAT1 reduced the occurrence of RSA in mice. Moreover, MALAT1 enhanced proliferation, migration, and invasion of trophoblast cells through recruiting CREBBP to promote MBD4 expression. Silencing of CREBBP or MBD4 increased embryonic resorption rate in RSA mice overexpressing MALAT1. DISCUSSION MALAT1 suppresses APL-positive RSA by promoting MBD4 transcription through recruitment of CREBBP to the MBD4 promoter region.

Effects of N Acetylcysteine on the Expression of Genes Associated with Reproductive Performance in the Goat Uterus during Early Gestation. Animals (Basel) 2022; 12:ani12182431.

Abstract
Simple Summary The uterus is an important place for mammals to nurture new life, and improving the physiological function of the uterus is important for improving the reproductive efficiency of mammals. NAC is a small-molecule antioxidant with a positive regulatory effect on mammalian reproductive performance. We found that NAC can alter the expression of uterine genes in goats in early gestation. These DEGs may regulate uterine performance in early pregnancy in goats by participating in signalling pathways related to reproductive regulation, resistance to oxidative stress, immune regulation, angiogenesis and development, cytokines, and cell adhesion. These findings provide a fundamental reference for the modulation of reproductive performance in goats in early gestation by NAC. Abstract N acetylcysteine (NAC) affects antioxidation and reactive oxygen species scavenging in the body and thereby promotes embryonic development and implantation and inhibits inflammation. The mechanism through which NAC regulates reproductive performance in the uteri of goats during early gestation remains unclear. In this study, the treatment group was fed 0.07% NAC for the first 35 days of gestation, whereas the control group received no NAC supplementation. The regulatory genes and key pathways associated with goat reproductive performance under NAC supplementation were identified by RNA-seq. RT–qPCR was used to verify the sequencing results and subsequently construct tissue expression profiles of the relevant genes. RNA-seq identified 19,796 genes coexpressed in the control and treatment groups and 1318 differentially expressed genes (DEGs), including 787 and 531 DEGs enriched in the treatment and control groups, respectively. A GO analysis revealed that the identified genes mapped to pathways such as cell activation, cytokine production, cell mitotic processes, and angiogenesis, and a KEGG enrichment analysis showed that the DEGs were enriched in pathways associated with reproductive regulation, immune regulation, resistance to oxidative stress, and cell adhesion. The RT–qPCR analysis showed that BDNF and CSF-1 were most highly expressed in the uterus, that WIF1 and ESR2 showed low expression in the uterus, and that CTSS, PTX3, and TGFβ-3 were most highly expressed in the oviduct, which indicated that these genes may be directly or indirectly involved in the modulation of reproduction in early-gestation goats. These findings provide fundamental data for the NAC-mediated modulation of the reproductive performance of goats during early gestation.

Long non-coding RNA LINC01347 suppresses trophoblast cell migration, invasion and EMT by regulating miR-101-3p/PTEN/AKT axis. Reprod Biol 2022; 22:100670. [PMID: 35810709 DOI: 10.1016/j.repbio.2022.100670] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/23/2022] [Revised: 06/11/2022] [Accepted: 06/27/2022] [Indexed: 10/17/2022]
Abstract
Recurrent miscarriage (RM) is one of the common complications of pregnancy, which is closely related to gene mutation. The profiling of non-coding RNAs showed that the expression level of long non-coding RNA LINC01347 (LINC01347) in the serum of patients with recurrent abortion was significantly increased, which could serve as a potential marker for early diagnosis. However, the biological functions of LINC01347 in the miscarriage remain to be elucidated. In this study, LINC01347 expression levels in HTR-8/SVneo cells and placenta samples were measured by RT-qPCR. The migration ability of HTR-8/SVneo cells was detected by wound-healing assay. Western blotting (WB) assay was conducted to measure E-cadherin, Vimentin, N-cadherin, PTEN, phospho-AKT(S473), phospho-AKT(T308) and AKT levels. Dual luciferase reporter assay and RNA pull-down analysis were performed to validate the molecular interactions. The results showed an upregulation of LINC01347 in the placenta samples of RM patients and HTR-8/SVneo cells. LINC01347 overexpression impaired the invasion and migration of trophoblast cells, while LINC01347 silencing promoted cell migration and invasion. LINC01347 level was also negatively correlated with the changes of epithelial-mesenchymal transition (EMT) markers in trophoblasts. We further demonstrated that miR-101-3p/PTEN/AKT axis played an important role in mediating the biological roles of LINC01347 in the invasion and migration of trophoblasts. In conclusion, our results revealed that LINC01347 suppresses the migratory ability and regulates the EMT processes in trophoblasts by regulating miR-101-3p/PTEN/AKT axis, suggesting that targeting LINC01347 may serve as a strategy to ameliorate RM.
