Abstract
There are a plethora of publications on the role of miRNA gene polymorphism and its association with recurrent pregnancy loss (RPL), but a lack of uniformity in the studies available due to the variable subject population, heterogeneity and contrary results of significance. Rigorous data mining was done through PubMed, SCOPUS, Cochrane library, Elsevier and Google Scholar to extract the studies of interest published until June 2021. A total of eight SNPs of miRNAs have been included, where ≥2 studies per SNPs were available. Analysis was done on the basis of pooled odds ratios and 95% CI. This is the first meta-analysis on miRNA SNPs in RPL that suggests that rs11614913, rs3746444 and rs2292832 biomarkers may decrease the risk of RPL under different genetic models.

Abstract
Ischemic stroke is a complicated disease, and its pathogenesis has been attributed to the occurrence of genetic polymorphisms. Evidence has suggested that the microRNA let-7a is involved in the pathogenesis of ischemic stroke. Pri-miRNA is the primary transcript, which undergoes several processing steps to generate pre-miRNA and, later, mature miRNAs. In this case-control study, we analyzed the distribution of pri-let-7a-2 variants in patients at a high risk for ischemic stroke and the interactions of pri-let-7a-2 variants and environmental factors. Blood samples and clinical information were collected from 1086 patients with ischemic stroke and 836 healthy controls between December 2013 and December 2015 at the First Affiliated Hospital of China Medical University. We found that the rs1143770 CC genotype and the C allele were associated with a decreased risk of ischemic stroke, whereas the rs629367 CC genotype was associated with an increased risk for ischemic stroke. Moreover, these two single-nucleotide polymorphisms were in linkage disequilibrium in this study sample. We analyzed gene-environment interactions and found that rs1143770 exerted a combined effect on the pathogenesis of ischemic stroke, together with alcohol use, smoking, and a history of hypertension. Therefore, the detection of pri-let-7a-2 polymorphisms may increase the awareness of ischemic stroke risk. This study was approved by the Institutional Ethics Committee of the First Affiliated Hospital of China Medical University, China (approval No. 2012-38-1) on February 20, 2012, and was registered with the Chinese Clinical Trial Registry (registration number: ChiCTR-COC-17013559) on December 27, 2017.

Abstract
A recent study of the ischemic stroke described the roles played by miRNAs in the downregulation of specific cell-cycle gene expression and it is thought to require the development of biomarkers for the prognostic of ischemic stroke. Here, we hypothesized that four miRNA polymorphisms (miR-10a, miR-27a, miR-34b/c, and miR-300) may affect stroke susceptibility and mortality. Blood samples were collected from 530 patients and 403 controls. Genetic polymorphisms were detected by polymerase chain reaction (PCR)-restriction fragment length polymorphism analysis and real-time PCR. We found that the miR-300 rs12894467 TC genotype and the dominant model (AOR: 2.069, p-value: 0.017; AOR: 1.931, p-value: 0.027) were significantly associated with an increased risk for the ischemic stroke subtype. In Cox proportional hazard regression models, the miR-10a rs3809783 A>T and miR-34b/c rs4938723 T>C polymorphisms were associated with the mortality rates among ischemic stroke patients. We found that a miR-300 polymorphism was associated with increased ischemic stroke susceptibility among the Korean population. Additionally, polymorphisms in miR-10a and miR-34b/c were associated with the increased or decreased mortality of ischemic stroke patients. This study marks the first report of an association between ischemic stroke and miRNA polymorphisms (miR-10aA>T, miR-27aT>C, miR-34b/cT>C, and miR-300T>C) in the Korean population.

Noncoding RNAs in Unexplained Recurrent Spontaneous Abortions and Their Diagnostic Potential. DISEASE MARKERS 2019; 2019:7090767.

Abstract
Unexplained recurrent spontaneous abortion (URSA) is defined as the loss of two or more consecutive pregnancies before the 20th week of gestation with normal findings on routine screening tests. Our understanding of the cellular and molecular pathogenesis of URSA is still far from complete. Noncoding RNAs (ncRNAs) play a pivotal role in transcription and expression. The functions of ncRNAs may also improve understanding of URSA pathogenesis. Because of their stability in the circulatory system and at the maternal-fetal interface, it may be possible to use ncRNAs as biomarkers for certain disease states. Here, we provide a narrative review of the current state of knowledge about ncRNAs associated with URSA. The possibility of developing a diagnostic tool using ncRNAs is discussed. The underlying mechanisms of how ncRNAs may lead to the onset of URSA are explored in this review.

Abstract
OBJECTIVES To investigate the role of long noncoding RNA (lncRNA) nuclear-enriched abundant transcript 1 (NEAT1) in regulating sorafenib (Sora) sensitivity of hepatocellular carcinoma (HCC) cells and possible signaling pathways. METHODS HCC cell lines and tumor tissue were quantified for NEAT1 expression by quantitative polymerase chain reaction (qPCR). Following shRNA (short hairpin RNA) knockdown of NEAT1, cell viability, apoptosis, and related protein expression were measured after drug treatment. The downstream target of NEAT1, including miR-335 and c-Met was studied using a combination of luciferase binding assay, gene knockdown/overexpression, western blot analysis, and cell viability/apoptosis assay. Cancer cells with NEAT1 knockdown were transplanted onto nude mice for in vivo tumorigenesis assay. RESULTS Silencing of NEAT1 in HCC cells facilitated Sora sensitivity by enhancing drug-induced apoptosis, and led to smaller tumor size on nude mice. Mechanistic study suggested that miR-335 was negatively regulated by NEAT1, and miR-335 further suppressed c-Met-Akt pathway, whose activation caused drug resistance of HCC cells. The knockdown of miR-335, or overexpression of c-Met, all remarkably abolished the proapoptotic effect of NEAT1 knockdown in HCC cells. CONCLUSION lncRNA NEAT1 mediates Sora resistance of HCC cells by suppressing miR-335 expression, and disinhibition on c-Met-Akt signaling pathway. Our results provide potency of NEAT1 as the biomarker for drug resistant HCC and possible treating targets.

Abstract
Background Survivin, a member of the inhibitor of apoptosis protein family, is highly expressed in many cancers and has important roles in inhibiting apoptosis by blocking caspase activation. However, its antitumor effects remain largely unknown. Here we explore the function of survivin in skin cancer. Methods We used qPCR and Western blot to examine survivin expression in skin cancer patients and cell line. We generated several survivin shRNA constructs and tested the effects of survivin shRNA on cancer cell viability using MTT assay, flow cytometry, and TUNEL assay. Results We found that survivin was upregulated in both skin cancer patients and skin cancer cell line A431. Knockdown survivin via shRNA inhibited cancer cell proliferation and promoted apoptosis in both A431 cell and in vivo xenograft tumor mouse model. The antitumor effect is comparable to resveratrol, a drug known to inhibit cancer progression. Moreover, we showed that inhibition of survivin was able to increase the expression of cleaved caspase 7/caspase 9 and activate the ataxia-telangiectasia mutated-NF-κB pathway in A431 cells. Conclusion Survivin-shRNA possesses antitumor abilities in vitro and in vivo by inhibiting the proliferation and promoting apoptosis of A431 cells. It may serve as a potential anticancer target for skin cancer therapy in the future.

Abstract
Little is known about the role of long non-coding RNA SNHG7-1 in the development of recurrent spontaneous abortion (RSA). The aim of the present study was to investigate the levels of SNHG7-1 in villi of RSA, and explore its underlying mechanism. The qRT-PCR assay SNHG7-1 showed that the expression level was downregulated in RSA and HTR-8/SVneo cells. In addition, the growth rate of cells transfected with si-SNHG7-1 was significantly decreased compared to that with si-NC, which was reversed by miR-34a targeted with 3'-UTR. Moreover, miR-34a suppressed the expression of WNT1 by binding with the 3'-UTR, which interact with WNT1 to inhibit the proliferation of cells. Furthermore, miR-34a inhibitor rescued the dysregulation of WNT1, p-β-catenin, β-catenin, cyclinD and c-Myc by si-SNHG7A-1. In short, the current study suggests SNHG7-1 plays as an important role in RSA progression targeted by miR-34a via Wnt/β-catenin signaling pathway, providing a novel insight for the pathogenesis and underlying therapeutic target for RSA.

Abstract
Single nucleotide polymorphisms (SNPs) in miRNAs are associated with the risk to development of certain human diseases and affect the regulatory capacity of miRNAs. However, the relationship between miRNAs polymorphisms and recurrent pregnancy loss (RPL) is still largely unknown. Our study found that one SNP rs56103835 T>C in miR-323b coding region was associated with the increase risk of human unexplained RPL (URPL), but no differences were found in another SNP rs75330474 C>T. However, in two-locus haplotype analysis, T-C haplotype was associated with an increased risk of URPL. The level of mature miR-323b was obviously up-regulated in cells transfected with T-C haplotype. T-C haplotype inhibited HTR-8/SVneo cells proliferation and migration and promoted cells apoptosis. Further experiments identified that paired-box 8 (Pax8) was a functionally relevant target of miR-323b, and its expression was reversely regulated by miR-323b. Besides, the expressions of Pax8 in villous chorionic tissues from URPL patients were lower than controls, contrary to the high expression of miR-323. More importantly, dual-luciferase assay indicated T-C haplotype, increasing miR-323b expression, could down-regulated Pax8 expression. Collectively, our data suggest that T-C haplotype in pre-miR-323b may aggravate the risk of developing URPL and influence the level of mature miR-323b and its target gene Pax8.

Abstract
We conducted this study to investigate the effects of the combination therapy of human chorionic gonadotropin (hCG) plus immunoglobulin (IG) on the levels of T helper 17 (Th17) cells and Foxp3+ regulatory T cells (Treg) in patients with unexplained recurrent spontaneous abortion (URSA). Twenty pregnant women with URSA underwent combination therapy of hCG plus IG. Flow cytometry was performed to measure the proportions of Th17 and Treg cells before and after treatment. RT-PCR and ELISA were applied to detect the concentrations of interleukin (IL)-17, IL-6, IL-10, and transforming growth factor (TGF)-β1 in the peripheral blood. The therapy of hCG combined with IG may induce a decrease in the Th17/Treg ratio and the Treg bias, which may be beneficial for the maintenance of pregnancy. The levels of Th17 cells and related cytokines IL-17 and IL-6 decreased after the treatment (P<0.05). At the same time, levels of Treg cells and the related cytokines IL-10 and TGF-β1 increased (P<0.05). The Th17/Treg ratio decreased significantly after treatment. In conclusion, the occurrence of URSA may be associated with the Th17/Treg balance disorder, and correcting the disorder may be one of the mechanisms behind the efficacy of combination therapy for URSA.

Abstract
Background In view of the important function of nuclear receptor liver receptor homolog 1 (LRH 1) in various biological processes and the physiological changes accompanying unexplained recurrent spontaneous abortion (USRA), our study was carried out to investigate the potential roles of LRH-1 in USRA. Material/Methods Thirty patients with URSA at early the early state of pregnancy were selected, and 30 patients with normal early pregnancy were also selected from Aug 2015 to Sep 2016 as a control group. The expression of LRH-1 protein in decidua and villi were detected by immunohistochemistry and Western blot analysis, and the expression of LRH-1 mRNA was detected by RT-PCR. The expression levels of CYP19 and P450scc were detected by RT-PCR and Western blot analysis at mRNA and protein levels, respectively. Results The levels of LRH-1, CYP19, and P450scc mRNA and protein in villi of the patients in the URSA group were significantly lower than in the control group. There were no significant differences between the URSA group and control group in the levels of LRH-1, CYP19, and P450scc mRNA and protein in villi in decidua. Conclusions URSA was related to the reduced expression level of LRH-1 in villous tissues but not in decidua, and expression of LRH-1 may be related to the expression of CYP19 and P450scc. We believe that the expression level of LRH-1 can be used as a marker in the early diagnosis of URSA, and the regulation of LRH-1 expression many lead to new URSA treatments.

Abstract
The establishment and maintenance of successful pregnancy mainly depends on trophoblast cells. Their dysfunction has been implicated in recurrent spontaneous abortion (RSA), a major complication of pregnancy. However, the underlying mechanisms of trophoblasts dysfunction remain unclear. DNA-damage-induced cell apoptosis has been reported to play a vital role in cell death. In this study, we identified a novel microRNA (miR-520) in RSA progression via regulating trophoblast cell apoptosis. Microarray analysis showed that miR-520 was highly expressed in villus of RSA patients. By using flow cytometry analysis, we observed miR-520 expression was correlated with human trophoblast cell apoptosis in vitro, along with decreased poly (ADP-ribose) polymerase-1 (PARP1) expression. With the analysis of clinic samples, we observed that miR-520 level was negatively correlated with PARP1 level in RSA villus. In addition, overexpression of PARP1 restored the miR-520-induced trophoblast cell apoptosis in vitro. The status of chromosome in trophoblast implied that miR-520-promoted DNA-damage-induced cell apoptosis to regulate RSA progression. These results indicated that the level of miR-520 might associate with RSA by prompting trophoblast cell apoptosis via PARP1 dependent DNA-damage pathway.

Reprod Biomed Online 2017; 34:399-405. [PMID: 28126236 DOI: 10.1016/j.rbmo.2017.01.005] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/14/2016] [Revised: 01/06/2017] [Accepted: 01/06/2017] [Indexed: 11/24/2022]
Abstract
Oestrogen receptors are implicated in the pathogenesis of recurrent spontaneous abortion (RSA). Non-genomic oestrogen responses can be mediated by GPER. The prevalence of polymorphisms in GPER1 gene in RSA was assessed in 747 Chinese women from Yunnan province (171 Bai, 258 Chinese Han, 234 Dai, 33 Achang and 51 Jingpo patients). Snapshot technology was used for genotyping the polymorphisms of the GPER1 gene. The rs4265085G was significantly increased in the Dai and Bai groups versus controls (Dai: P < 0.0001, Padj < 0.0001, OR 95% CI 2.34 [1.79 to 3.05]; Bai: P = 0.0004, Padj = 0.0012, OR 95% CI 1.71 [1.27 to 2.31]); recessive model of rs4265085 in the Dai (P = 0.003, Padj = 0.009, OR 95% CI 2.71 [1.38 to 5.30]); Bai (P < 0.0001, Padj < 0.0001, OR 95% CI 3.37 [1.93 to 5.91]). Haplotype frequencies containing rs10269151G-rs4265085G-rs11544331C were separately significantly different in Dai and Bai ethnic groups (Dai: P = 0.0002, Padj = 0.001, OR 95% CI = 2.12 [1.43 to 3.17]; Bai: P = 0.005, Padj = 0.025, OR 95% CI = 1.82 [1.18 to 2.78]) compared with controls. The intron variant rs4265085 may confer risk for RSA in Dai and Bai ethnic groups.
