Abstract
The clustered homeobox gene family known as the Hox family plays a fundamental role in the morphogenesis of the vertebrate's embryo. A long noncoding RNA (lncRNA), known as HOTTIP (HOXA transcript at the distal tip), has been functionally characterized and contributed to the pathogenesis of various conditions. The current case-control study was undertaken to examine the gene frequencies and shared alleles of the HOTTIP gene in Iranian participants with or without idiopathic recurrent spontaneous abortion (RSA). Both ARMS-PCR reaction and RFLP-PCR techniques were employed to detect three HOTTIP polymorphisms (rs2023843C/T, rs78248039A/T, and rs1859168C/A) in a DNA sample of 161 women with RSA and 177 healthy women. We found that the TT genotype of the HOTTIP rs2023843 C/T polymorphism was associated with a lower risk for idiopathic RSA. In contrast, the TT genotype of the HOTTIP rs78248039 A/T polymorphism was correlated with an enhanced risk of RSA. The presence of the A-allele for HOTTIP rs1859168 C/A polymorphism was associated with an increased risk for idiopathic RSA. Haplotype analysis showed that the T/T/A, C/T/A, T/T/C, and T/A/A haplotypes of rs2023843/rs78248039/rs1859168 enhanced RSA susceptibility. Computational analysis predicted that this lncRNA might act as a potential sponge for some microRNAs; therefore, affecting the expression of genes being targeted by them. In addition, both rs2023843 and rs1859168 variants could alter the local secondary structure of HOTTIP. Our results showed that HOTTIP rs2023843C/T, rs78248039A/T, and rs1859168C/A polymorphisms may confer genetic susceptibility to idiopathic RSA in an Iranian population.

Abstract
OBJECTIVE This study aimed to explore the specific pathways by which HOX transcript antisense intergenic RNA contributes to the pathogenesis of unexplained recurrent spontaneous abortion. METHODS Real-time quantitative PCR was employed to assess the differential expression levels of HOX transcript antisense intergenic RNA in chorionic villi tissues from unexplained recurrent spontaneous abortion patients and women with voluntarily terminated pregnancies. HTR-8/SVneo served as a cellular model. Knockdown and overexpression of HOX transcript antisense intergenic RNA in the cells were achieved through siRNA transfection and pcDNA3.1 transfection, respectively. Cell viability, migration, and invasion were evaluated using cell counting kit-8, scratch, and Transwell assays, respectively. The interaction among the HOX transcript antisense intergenic RNA /miR-1277-5p/fibrillin 2 axis was predicted through bioinformatics analysis and confirmed through in vitro experiments. Furthermore, the regulatory effects of the HOX transcript antisense intergenic RNA /miR-1277-5p/fibrillin 2 signaling axis on cellular behaviors were validated in HTR-8/SVneo cells. RESULTS We found that HOX transcript antisense intergenic RNA was downregulated in chorionic villi tissues from unexplained recurrent spontaneous abortion patients. Overexpression of HOX transcript antisense intergenic RNA significantly enhanced the viability, migration, and invasion of HTR-8/SVneo cells, while knockdown of HOX transcript antisense intergenic RNA had the opposite effects. We further confirmed the regulatory effect of the HOX transcript antisense intergenic RNA /miR-1277-5p/fibrillin 2 signaling axis in unexplained recurrent spontaneous abortion. Specifically, HOX transcript antisense intergenic RNA and fibrillin 2 were found to reduce the risk of unexplained recurrent spontaneous abortion by enhancing cell viability, migration, and invasion, whereas miR-1277-5p exerted the opposite effects. CONCLUSION HOX transcript antisense intergenic RNA promotes unexplained recurrent spontaneous abortion development by targeting inhibition of miR-1277-5p/fibrillin 2 axis.

Abstract
ABSTRACT Accumulating studies have demonstrated that non-coding RNAs (ncRNAs), functioning as important regulators of transcription and translation, are involved in the establishment and maintenance of pregnancy, especially the maternal immune adaptation process. The endometrial stromal cells (ESCs), trophoblast cells, and decidua immune cells that reside at the maternal-fetal interface are thought to play significant roles in normal pregnancy and pregnancy-associated diseases. Here, we reviewed the up-to-date evidence on how microRNA, long non-coding RNA, and circular RNA regulate ESCs, trophoblast cells, and immune cells and discussed the potential applications of these ncRNAs as diagnostic and therapeutic markers in pregnancy complications.

Abstract
Recurrent pregnancy loss is a common obstetric complication affecting approximately 1-2% of reproductive population worldwide, but the precise causes for approximately a half of such patients remain unexplained. In this study, we compared the expression profiles of messenger RNA (mRNA), long non-coding RNA (lncRNA), microRNA (miRNA), and circular RNA (circRNA) in villi tissues from patients with unexplained recurrent pregnancy loss (URPL) and elective termination of pregnancy (ETP) using whole-transcriptome sequencing. A number of differentially expressed RNAs were confirmed by real-time PCR analysis. As a result, we identified a total of 1,703 mRNAs, 798 lncRNAs, 199 miRNAs, and 163 circRNAs that were significantly differentially expressed between villi tissues from URPL and ETP. The data of real-time PCR were consistent with those of the sequencing results. Gene ontology and Kyoto Encyclopedia of Genes and Genomes pathway analysis revealed that the majority of differentially expressed mRNAs and target genes of ncRNAs were associated with focal adhesion, extracellular matrix-receptor interaction, and the PI3K-Akt signaling pathway. Additionally, two co-expression networks (lncRNA-miRNA-mRNA and lncRNA-circRNA-miRNA-mRNA) were constructed based on the correlation analysis between the differentially expressed RNAs. Taken together, this study provides a large number of valuable candidates for elucidating regulatory mechanisms of ncRNAs, which may ultimately assist in understanding the pathogenesis of URPL.

Abstract
Spontaneous abortion is a common pregnancy complication that negatively impacts women’s health and commercial pig production. It has been demonstrated that non-coding RNA (ncRNA) is involved in SA by affecting cell proliferation, invasion, apoptosis, epithelial-mesenchymal transformation (EMT), migration, and immune response. Over the last decade, research on ncRNAs in SA has primarily concentrated on micro RNAs (miRNAs), long non-coding RNAs (lncRNAs), and circular RNAs (circRNAs). In this review, we discuss recent ncRNA studies focused on the function and mechanism of miRNAs, lncRNAs, and circRNAs in regulating SA. Meanwhile, we suggest that a ceRNA regulatory network exists in the onset and development of SA. A deeper understanding of this network will accelerate the process of the quest for potential RNA markers for SA diagnosis and treatment.

Long Non-Coding RNA ZEB2-AS1 Augments Activity of Trophoblast Cells and Prevents the Development of Recurrent Spontaneous Abortion in Mice Through EZH2-Mediated CST3 Inhibition.

Abstract
Recurrent spontaneous abortion (RSA) is the most common complication of pregnancy where reduced invasion of trophoblasts plays a major role. This work aimed to explore the effect of abnormally expressed long non-coding RNA (lncRNA) ZEB2-AS1 on the occurrence of RSA. Differentially expressed lncRNAs in trophoblast cells between healthy controls and patients with RSA were screened using the GEO database. Female CBA/J mice were allowed to mate with male DBA/2 mice to establish inbred mice with RSA. ZEB2-AS1 was poorly expressed in placental tissues and trophoblast cells in the condition of RSA. ZEB2-AS1 upregulation augmented proliferation, migration, and invasion of trophoblast cells in vitro. ZEB2-AS1 negatively regulated cystatin C (CST3) expression. Further overexpression of CST3 blocked the activity of trophoblast cells. ZEB2-AS1 recruited enhancer of EZH2 to the promoter region of CST3, which increased H3K27me3 modification to suppress CST3 expression. In vivo, overexpression of ZEB2-AS1 reduced embryo resorption rate and increased the weights of fetuses and placentas in mice with RSA. However, the protective roles of ZEB2-AS1 were blocked upon artificial silencing of EZH2 or upregulation of CST3. Taken together, this study demonstrates that ZEB2-AS1 enhances activity of trophoblast cells and prevents RSA development through reducing CST3 expression in an EZH2-dependent manner.

Abstract
Unexplained recurrent spontaneous abortion (URSA) is one of the most intractable clinical challenges in reproduction. As a specific type of endogenous non-coding RNA, circular RNAs (circRNAs) have great pre-clinical diagnostic and therapeutic values in diseases. Recently, thousands of circRNAs were detected in human pre-implantation embryos, indicating that circRNAs potentially have important regulatory functions. However, the roles of circRNAs in URSA remain largely unknown. In this study, we elucidated deregulated circRNA expression and distinct competing endogenous RNA (ceRNA) networks by comparing URSA placental villus with that of patients with normal pregnancy using microarrays. We characterized a distinct circRNA, circRNA-0050703, which is downregulated in URSA placental villus (thus we named it circRNA-DURSA). Silencing of circRNA-DURSA results in trophoblast cell apoptosis in vitro. Furthermore, mechanistic dissection revealed that circRNA-DURSA exerts its effects by competitively binding to miR-760, which post-transcriptionally targets HIST1H2BE. Additionally, after circRNA-DURSA silencing in vivo, the numbers of implanted embryos decreased significantly. These results reveal the regulatory roles of circRNA-DURSA in trophoblasts and identified a distinct circRNA-DURSA/miR-760/HIST1H2BE axis as potentially important diagnostic and therapeutic targets for URSA treatment.

Abstract
Background Recurrent spontaneous abortion (RSA) is one of the common complication of pregnancy, bringing heavy burden to the patients and their families. The study aimed to explore the lncRNA-miRNA-mRNA network associated with recurrent spontaneous abortion. Methods By transcriptome sequencing, we detected differences in lncRNA, miRNA and mRNA expression in villus tissue samples collected from 3 patients with RSA and 3 normal abortion patients. Differentially expressed lncRNAs, miRNAs and genes (DELs, DEMs and DEGs, respectively) were identified, and Geno Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) analyses were used to determine the functions of DELs and DEGs, which were analysed by Fisher’s test. We also observed the regulatory relationships between miRNA-mRNA and lncRNA-miRNA by Cytoscape 3.6.1. Results The results showed that 1008 DELs (523 upregulated and 485 downregulated), 475 DEGs (201 upregulated and 274 downregulated) and 37 DEMs (15 upregulated and 22 downregulated) were identified. And we also constructed a novel lncRNA-related ceRNA network containing 31 lncRNAs, 1 miRNA (hsa-miR-210-5p) and 3 genes (NTNG2, GRIA1 and AQP1). Conclusions lncRNA-related ceRNA network containing 31 lncRNAs, 1 miRNA (hsa-miR-210-5p) and 3 mRNAs (NTNG2, GRIA1 and AQP1) was constructed. The results may provide a basic theory for elucidating the mechanism underlying RSA.

[PMID: 34474977 DOI: 10.1016/j.rbmo.2021.06.023] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/10/2021] [Revised: 06/13/2021] [Accepted: 06/22/2021] [Indexed: 01/23/2023]
Abstract
RESEARCH QUESTION lncRNA IGF2-AS may be related to early pregnancy loss. Does lncRNA IGF2-AS affect trophoblast cell growth? The aim of the present study was to verify that lncRNA IGF2-AS encodes a polypeptide, IGF2-AS-168aa, and to study its role in the pathogenesis of trophoblasts. DESIGN A small interfering RNA targeted to the IGF2-AS gene (si-IGF2-AS) was designed and transfected into JEG-3 and JAR cells for in-vitro gene silencing. Quantitative polymerase chain reaction and western blotting were used to determine lncRNA IGF2-AS levels in experimental cells. After IGF2-AS suppression, MTT assay was used to assess cell proliferation and apoptosis was determined by flow cytometry. Target gRNA IGF2-AS-gRNA was designed for knockout conducted the corresponding mRNA. HEK293T cells were transfected with the identified positive clone vectors. Finally, IGF2-AS-168aa was analysed by western blotting after the protein-coding region of the IGF2-AS gene was knocked out by CRISPR/Cas9 gene-editing technology. RESULTS lncRNA IGF2-AS and IGF2-AS-168aa were significantly downregulated in JEG-3 and JAR cells transfected with si-IGF2-AS (lncRNA IGF2-AS: JAR: NC versus small interfering RNA (siRNA)-1: P = 0.019 NC versus siRNA-2: P = 0.013; JEG-3: NC versus siRNA-1: P = 0.001 NC versus siRNA-2: P = 0.004) (IGF2-AS-168aa: JAR: NC versus siRNA-1: P = 0.030 NC versus siRNA-2: P = 0.018; JEG-3: NC versus siRNA-1: P = 0.004 NC versus siRNA-2: P = 0.001). IGF2-AS gene was incapable of encoding IGF2-AS-168aa after the coding region was successfully knocked out in HEK293T cells. Flow cytometry and the MTT assay revealed that IGF2-AS gene silencing led to cell cycle block in the G1 phase, markedly decreasing cell proliferation and increasing apoptosis. CONCLUSION The IGF2-AS gene encoded a peptide with a potential function in trophoblast cell cycle arrest.

Molecular epigenetic dynamics in breast carcinogenesis. Arch Pharm Res 2021; 44:741-763. [PMID: 34392501 DOI: 10.1007/s12272-021-01348-0] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/02/2021] [Accepted: 08/03/2021] [Indexed: 12/12/2022]
Abstract
Breast cancer has become one of the most common dreadful diseases that target women across the globe. The most obvious reasons we associate with it are either genetic mutations or dysregulation of pathways. However, there is yet another domain that has a significant role in influencing the genetic mutations and pathways. Epigenetic mechanisms influence these pathways either independently or in association with genetic mutations, thereby expediting the process of breast carcinogenesis. Breast cancer is governed by various transduction pathways such as PI3K/AKT/mTOR, NOTCH, β Catenin, NF-kB, Hedgehog, etc. There are many proteins as well that serve to be tumor suppressors but somehow lose their ability to function. This may be because of either genetic mutation or a process that represses their function. Apart from these, there are a lot of individual factors like puberty, breastfeeding, abortion, parity, circadian rhythm, alcohol consumption, pollutants, and obesity that drive these mutations and hence alter the pathways. Epigenetic mechanisms like DNA methylation, histone modifications, and lncRNAs directly or indirectly bring alterations in the proteins that are involved in the pathways. They do this by either promoting the transcription of genes or by repressing it at the ground genetic level that advances breast carcinogenesis. Epigenetics precedes genetic mutation in driving carcinogenesis and so, it needs to be explored further to diversify the possibilities of target specific treatments. In this review, the general role of DNA methylation, histone modification, and lncRNAs in breast cancer and their role in influencing the oncogenic signaling pathways along with the various factors governing them have been discussed for a better understanding of the role of epigenetics in breast carcinogenesis.

J Obstet Gynaecol Res 2021; 47:3767-3778. [PMID: 34396639 DOI: 10.1111/jog.14977] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/11/2021] [Revised: 06/26/2021] [Accepted: 07/29/2021] [Indexed: 11/30/2022]
Abstract
AIM To investigate the association between Hox transcript antisenses RNA (HOTAIR) polymorphisms, rs12826786 C/T, rs920778 T/C, rs4759314 A/G, and rs1899663 G/T, with recurrent spontaneous abortion (RSA) susceptibility in the Iranian women. METHODS We enrolled 161 patients diagnosed with RSA and 177 healthy women with at least one live birth without a history of abortion. Genotyping of HOTAIR polymorphisms was carried out using both restriction fragment length polymorphism-polymerase chain reaction and amplification refractory mutation system-polymerase chain reaction methods. Odds ratios (ORs) with 95% confidence intervals (CIs) were assessed to estimate the strength of association. RESULTS Different inheritance models of rs12826786 C/T, rs920778 T/C, and rs1899663 G/T polymorphisms significantly enhanced the risk of RSA (p < 0.05), whereas the rs4759314 A/G polymorphism was correlated with diminished risk of developing RSA under recessive AA versus GA + GG (OR 0.42 [95% CI = 0.19-0.91]), log-additive GG versus GA vs. GG (OR 0.67 [95% CI = 0.48-0.93]), and allelic A versus G (OR 0.65 [95% CI = 0.47-0.92]) models. Moreover, the TGTC, TTCT, TTTC, CGTC, CGTT, CTCC, CTCT, CTTC, and CTTT haplotypes of rs920778/rs1899663/rs12826786/ significantly increased the risk of RSA. The studied variants were not in strong linkage disequilibrium. CONCLUSIONS Our results indicated that variations in the HOTAIR gene might serve as beneficial biomarkers for determining susceptibility to RSA. To confirm these findings, replication studies with a larger population and different races are needed.

Abstract
AIMS Recurrent pregnancy loss (RPL), with unknown causes, is one of the most common challenges facing pregnancy. Apoptotic signaling pathways are involved in the normal and abnormal pregnancy process. Despite the evidence pointing toward the aberrant expression of apoptotic and apoptotic-related genes in pregnancy complications, the involvement of these genes in RPL remains to be elucidated. This study aimed to investigate the expression levels of BAX, MEG3, and miR-214-3p (as a microRNA), and their associations in an Iranian population. MATERIALS AND METHODS Following the extraction of RNA from blood samples of RPL patients and controls, quantitative expression levels of BAX, MEG3, and miR-214-3p genes were analyzed by real-time RT-PCR. RESULTS The findings showed that the expression levels of BAX and miRNA-214-3p were significantly higher in the blood samples of RPL patients than in control samples. In contrast, the expression of MEG3 was significantly down-regulated in women RPL. Furthermore, altered expressions of MEG3 and miRNA-214-3p are associated with their target gene BAX, where the BAX expression is positively and negatively correlated with the expressions of has-miR-214-3P and MEG3, respectively. ROC curve evaluation demonstrated the highest specificity and diagnostic value for miR-214-3p expression in distinguishing RPL samples from the healthy controls. CONCLUSIONS These data indicated that the aberrant expression of BAX, MEG3, miRNA-214-3p genes in RPL patients could provide new insights into the biological characteristics and related pathways of differentially expressed genes, which could help as potential diagnostic biomarkers and a better understanding of the molecular mechanisms of RPL.

Maternal DNA Methylation During Pregnancy: a Review. Reprod Sci 2021; 28:2758-2769.

Abstract
Multiple environmental, behavioral, and hereditary factors affect pregnancy. Recent studies suggest that epigenetic modifications, such as DNA methylation (DNAm), affect both maternal and fetal health during the period of gestation. Some of the pregnancy-related risk factors can influence maternal DNAm, thus predisposing both the mother and the neonate to clinical adversities with long-lasting consequences. DNAm alterations in the promoter and enhancer regions modulate gene expression changes which play vital physiological role. In this review, we have discussed the recent advances in our understanding of maternal DNA methylation changes during pregnancy and its associated complications such as gestational diabetes and anemia, adverse pregnancy outcomes like preterm birth, and preeclampsia. We have also highlighted some major gaps and limitations in the area which if addressed might improve our understanding of pregnancy and its associated adverse clinical conditions, ultimately leading to healthy pregnancies and reduction of public health burden.

Abstract
Spontaneous abortion (SA) is the spontaneous loss of a pregnancy before 20 gestational weeks. The causes of SA are still largely unknown. Long noncoding RNA (lncRNA) urothelial cancer associated 1 (UCA1) plays an important role in cellular progress. However, there is no report focusing on the role of UCA1 in SA. Here, we revealed that, compared with that in clinical samples from elective induced abortion, UCA1 expression was decreased in samples from SA patients as shown by qPCR method. The results demonstrated that UCA1 might be involved in the progress of SA. Then, we found that knockdown of UCA1 reduced cell viability and inhibited cell proliferation and migration of HTR-8/SVneo trophoblast cells as shown by CCK8, EdU, and Transwell methods. Furthermore, we demonstrated that UCA1 could act as a molecular sponge for miR-455 in HTR-8/SVneo cells as shown by luciferase reporter system method. In addition, miR-455 inhibited cell viability, cell proliferation and migration via regulating RUNX2 in HTR-8/SVneo cells. Ultimately, we illustrated that UCA1 plays its role via absorbing miR-455, thus promoting RUNX2 expression in HTR-8/SVneo cells. Collectively, this study first revealed the role and mechanism of UCA1 in the growth and migration of HTR-8/SVneo cells, indicating its potential as a diagnostic biomarker and therapeutic target for SA.

Abstract
This study aimed to investigate the mechanism by which MALAT1 regulates CRY2 expression and participates in trophoblast migration and invasion. Three patients with unexplained recurrent spontaneous abortion, four patients with missed abortion, and four women who underwent artificial miscarriages were enrolled in this study. Quantitative reverse-transcription polymerase chain reaction and western blot analysis were used to detect RNA and protein expression, respectively. Trophoblast migration and invasion were detected by wound-healing and transwell invasion assays. RNA pull-down and Co-IP assays were used to indicate the interaction between MALAT1 and FBXW7 or the interaction between FBXW7 and CRY2. The results showed significantly decreased MALAT1 expression in the villous specimens from the RSA patients relative to that in the villous specimens from the missed abortion patients and the normal villous specimens. MALAT1 promoted trophoblast cell migration and invasion by negatively regulating CRY2 protein expression. MALAT1 recruited FBXW7 to impair CRY2 protein stability. In conclusion, MALAT1 downregulation in trophoblasts might be related to miscarriage. MALAT1 may recruit the E3 ubiquitin ligase FBXW7 to induce CRY2 ubiquitin-mediated degradation and participate in trophoblast migration and invasion.

The Efficacy of Traditional Chinese Medicine Shoutai Pill Combined with Western Medicine in the First Trimester of Pregnancy in Women with Unexplained Recurrent Spontaneous Abortion: A Systematic Review and Meta-Analysis. BIOMED RESEARCH INTERNATIONAL 2020; 2020:7495161. [PMID: 32851085 PMCID: PMC7436282 DOI: 10.1155/2020/7495161] [Citation(s) in RCA: 12] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 04/27/2020] [Accepted: 07/16/2020] [Indexed: 02/06/2023]
Abstract
Background Shoutai Pill (STP), a famous classic herbal formula documented in traditional Chinese medicine (TCM), is widely available in China for treating unexplained recurrent spontaneous abortion (URSA). This systematic review and meta-analysis aims at evaluating the efficacy and safety of STP in the first trimester of pregnancy in women with a history of unexplained recurrent spontaneous abortion. Methods The following eight databases were searched from their establishment to Dec 31, 2019, for randomized controlled trials (RCTs): PubMed, Embase, Cochrane Library, Web of Science, China National Knowledge Infrastructure (CNKI), the Chinese BioMedical database (CBM), Chinese Scientific Journal Database (VIP), and the Wanfang database. The quality of evidence was estimated by the Grading of Recommendations Assessment, Development, and Evaluation (GRADE). Results A total of 12 studies (916 patients) with URSA were contained in this meta-analysis. The forest plot showed that patients treated with Shoutai Pill and western medicine had a significantly lower incidence of early pregnancy loss (RR: 0.42; 95% CI: 0.34–0.52; P < 0.01, I2 = 0%). Subgroup analysis revealed that different types of TCM syndrome differentiation had the similar results. Also, in the combined group, patients had a lower TCM syndromes and symptoms and serum D-dimer level, while higher incidence of live birth. Conclusions Our findings suggest that cotreatment with STP and western medicine might be superior to western medicine alone in the first trimester of pregnancy to prevent miscarriage in women with unexplained recurrent spontaneous abortion, and there was no adverse event in the experimental group reported. However, the methodological quality of included RCTs was unsatisfactory; it is necessary to verify its effectiveness with further more standardized researches of rigorous design.
