Int J Gynaecol Obstet 2024; 166:99-106. [PMID: 38650387 DOI: 10.1002/ijgo.15547] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/10/2023] [Revised: 03/04/2024] [Accepted: 04/04/2024] [Indexed: 04/25/2024]
Abstract
OBJECTIVE Tubal ectopic pregnancy (EP) is a leading cause of maternal morbidity and mortality. Studies have suggested that infection-induced inflammatory responses are major risk factors for EP. The aim of the present study was to find an association between MMP2 and CD63 gene variants and risk of EP during Chlamydia trachomatis infection in an Indian population. METHODS Fallopian tube samples of 120 EP and 120 tubal ligation women were collected. C. trachomatis was detected by PCR. The genotyping of MMP2 (rs17859882 G/T, rs7201A/C) and CD63(rs2231464 C/T, rs376086542 A/G) gene variants was done by qualitative real-time PCR using allelic discrimination method (VIC- and FAM-labeled). RESULTS The frequency of GG or GT genotype of MMP2 G/T polymorphism (rs17859882) was 66.6% in infected EP and 36.7% in uninfected EP and 22% in tubal ligation controls (P < 0.0001), while the frequency of AC or CC genotype of MMP2 A/C polymorphism (rs7201) was 66.6% in infected EP and 20.6% in uninfected EP and 13.5% in tubal ligation controls (P < 0.0001). The frequency of CT or TT genotype of CD63 C/T polymorphism (rs2231464) was 74% in infected EP and 21.8% in uninfected EP and 11.8% tubal ligation controls (P < 0.0001), while the frequency of AG or GG genotype of CD63 A/G polymorphism (rs376086542) was 48.1% in infected EP and 41.3% in uninfected EP and 18.6% tubal ligation controls (P < 0.0001). CONCLUSIONS The present study revealed a strong association between the presence of gene variants MMP2 (rs17859882 G/T, rs7201A/C) and CD63 (rs2231464 C/T, rs376086542 A/G) and risk of tubal EP during C. trachomatis infection.

Abstract
Recurrent pregnancy loss (RPL) is a condition characterized by the loss of two or more pregnancies before 20 weeks of gestation. The causes of RPL are complex and can be due to a variety of factors, including genetic, immunological, hormonal, and environmental factors. This transcriptome data mining study was done to explore the differentially expressed genes (DEGs) and related pathways responsible for pathogenesis of RPL using an Insilco approach. RNAseq datasets from the Gene Expression Omnibus (GEO) database was used to extract RNAseq datasets of RPL. Meta-analysis was done by ExpressAnalyst. The functional and pathway enrichment analysis of DEGs were performed using KEGG and BINGO plugin of Cytoscape software. Protein-protein interaction was done using STRING and hub genes were identified. A total of 91 DEGs were identified, out of which 10 were downregulated and 81 were upregulated. Pathway analysis indicated that majority of DEGs were enriched in immunological pathways (IL-17 signalling pathway, TLR-signalling pathway, autoimmune thyroid disease), angiogenic VEGF-signalling pathway and cell-cycle signalling pathways. Of these, 10 hub genes with high connectivity were selected (CXCL8, CCND1, FOS, PTGS2, CTLA4, THBS1, MMP2, KDR, and CD80). Most of these genes are involved in maintenance of immune response at maternal-fetal interface. Further, in functional enrichment analyses revealed the highest node size in regulation of biological processes followed by cellular processes, their regulation and regulation of multicellular organismal process. This in-silico transcriptomics meta-analysis findings could potentially contribute in identifying novel biomarkers and therapeutic targets for RPL, which could lead to the development of new diagnostic and therapeutic strategies for this condition.

Abstract
By promoting tissue invasion, cell growth and angiogenesis, the Y-box binding protein (YB-1) became famous as multifunctional oncoprotein. However, this designation is telling only part of the story. There is one particular time in life when actual tumorigenic-like processes become undoubtedly welcome, namely pregnancy. It seems therefore reasonable that YB-1 plays also a crucial role in reproduction, and yet this biological aspect of the cold-shock protein has been overlooked for many years. To overcome this limitation, we would like to propose a new perspective on YB-1 and emphasize its pivotal functions in healthy pregnancy and pregnancy-related complications. Moreover, we will discuss findings obtained from cancer research in the light of reproductive events to elucidate the importance of YB-1 at the feto-maternal interface.

Abstract
Recurrent miscarriage (RM) is a major reproductive health issue. RM is a multi-factorial disease, and is affected by environmental, genetic, and epigenetic factors. Genetics has a common role in recurrent miscarriage occurrence. It seems that molecular genetics has a great role in RSA incidence. So, in these years, RM has become for a major subject of genetics research. There are many genes that are involved in each phase for successful reproduction. This research aimed to evaluate the effect of all studied polymorphisms in studies on RSA that have not been included in any meta-analysis. PubMed, Scopus, and Web of Science databases were recruited to investigate the related articles. The systematic review results identified 143 studies worldwide. Thirteen genes have been included in assessing the case-control studies. Sixty-four SNPs were recruited to assess the association between genetic factors and RSA susceptibility. Ninety-two studies containing twenty two SNPs (from 10 genes) were included in the quantitative analysis. Bioinformatic analysis indicated that rs12722482 showed "Damaging Status" by double servers, and rs315952 and rs854560 had "Possibly damaging" status in the PolyPhen-2 server. MethPrimer server indicated that there is "CpG Island" in the rs10895068, rs1130355, and rs41557518 variants, and rs10895068-G allele makes a CpG dinucleotide which can change the gene methylation and result in altering the gene expression. So, further studies on rs12722482 and rs10895068 can demonstrate valuable results. To the best of our knowledge, this systematic review has covered the all studied polymorphisms of HLA-C, HLA-G, PON1, AGTR1, TAFI, FAS, FAS-L, ESR1, PGR, CTLA-4, MMP-2, MMP-3, MMP-9, and IL1RN for the first time. Also, we did a novel meta-analysis for AGTR1 rs5186, TAFI rs1926447, rs3742264, HLA-G rs1063320, rs1233334, rs1736936, rs2249863, PON1 rs662, rs854560, FAS rs2234767, rs1800682, FAS-L rs763110, ESR1, rs9340799, rs3798759, PGR rs1042838, CTLA4 rs4553808, rs5742909, rs231775, rs3087243, and MMP-2 rs243865 and updated statistical finding for rs2234693 and rs371194629. Rs2234693, rs9340799, rs231775, and rs371194629 demonstrated a significant association with RSA risk. Some variations showed significant association, while further studies are suggested to confirm the results. Finally, Rs4553808 and rs5742909 revealed no significant deviation in the results. It is suggested that these SNPs may be excluded from subsequent case-control studies or other analyses.

Abstract
Vascular complications are the leading cause of increased morbidity and mortality of diabetic patients. It has been postulated that matrix metalloproteinases MMP-2 and MMP-9, zinc-dependent endopeptidases through remodeling of the extracellular matrix, can contribute to the onset and progression of diabetic vascular complications. The aim of our study was to assess whether there is a major difference in single nucleotide polymorphisms in the MMP-2 (at position -1306C˃T) and MMP-9 (at position -1562C˃T) gene in type 2 diabetic patients and healthy controls and to determine whether there is an association of these gene variants with the presence of microvascular complications in diabetic patients. Our study included 102 type 2 diabetes patients and a control group which was comprised of 56 healthy controls. All diabetic patients were screened for microvascular diabetes complications. Genotypes were detected by polymerase chain reactions followed by restriction analyses with specific endonucleases and their frequencies were determined. The MMP-2 variant -1306C>T showed a negative correlation with type 2 diabetes (p=0.028). It was also shown that the presence of the -1306C allele increases the probability of developing type 2 diabetes. This was a 2.2 fold increase and that the -1306 T allele has a protective role in regards to type 2 diabetes. The MMP-2 variant -1306T showed a negative correlation with diabetic polyneuropathy (p=0.017), meaning that allele-1306T has a protective role in regards to diabetic polyneuropathy while the presence of allele -1306C increases the probability of developing diabetic polyneuropathy by 3.4 fold. Our study showed that the MMP-2 gene variant (-1306C) doubles the risk of developing type 2 diabetes, and for the first time an association of this gene variant and the presence of diabetic polyneuropathy was shown.

Abstract
The associations of ACE I/D and PAI-1 4G/5G polymorphisms with recurrent pregnancy loss (RPL) in Iranian women have yielded controversial results. Thus, we conducted a meta-analysis to obtain more certain results. A comprehensive literature search was performed in the PubMed, Web of Sciences, Scopus, MedRxiv, SID, and CNKI databases up to January 1st, 2021, using the appropriate terms. All case-control studies were included. Odds ratios (ORs) and 95% confidence intervals (CIs) were used to estimate the strength of associations. A total of 14 studies including eight studies with 783 patients and 761 healthy subjects on ACE I/D and six studies with 1.155 patients and 699 healthy subjects on PAI-1 4G/5G were included. Combined data revealed that ACE I/D polymorphism was significantly associated with RPL risk in Iranian women under three models i.e., allele [OR=0.744, 95% CI: (0.640-0.864); p≤0.001], dominant [OR=0.774, 95% CI: (0.601-0.996); p=0.047], and recessive [OR=0.767, 95% CI: (0.611-0.963); p=0.022]. Moreover, the pooled data showed a significant association between the PAI-1 4G/5G polymorphism and RPL risk under all five models i.e., allele [OR=2.352, 95% CI: (1.623-3.408); p≤0.001], heterozygote [OR=8.364, 95% CI: (4.744-14.756); p≤0.001), homozygote [OR=2.192, 95% CI: (1.093-4.394); p=0.027), dominant [OR=2.354, 95% CI: (1.309-4.235); p=0.004], and recessive [OR=5.208, 95% CI: (3.005-9.025); p≤0.001]. Stratification analysis revealed that these polymorphisms were associated with RPL risk by the number of miscarriages. Our pooled data indicated that ACE I/D and PAI-1 4G/5G polymorphisms were significantly associated with an increased risk of RPL in Iranian women. These significant findings showed that the investigation might be adequate for ACE I/D and PAI-1 4G/5G polymorphisms in the Iranian population.

Association of MMP2 and MMP9 gene polymorphisms with the recurrent spontaneous abortion: A meta-analysis. Gene 2020; 767:145173. [PMID: 33007375 DOI: 10.1016/j.gene.2020.145173] [Citation(s) in RCA: 13] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/08/2020] [Revised: 07/26/2020] [Accepted: 09/23/2020] [Indexed: 12/15/2022]
Abstract
BACKGROUND Recurrent spontaneous abortion (RSA) accounts for the most common complication of early pregnancy in humans. Matrix metalloproteinases (MMPs) play important regulatory roles in implantation and placentation to ensure a successful pregnancy. Single nucleotide polymorphisms (SNPs) have been identified in the promoters of MMP2 and MMP9 genes. However, the associations between MMP2 and MMP9 SNPs and the RSA risk remain unclear. The aim of this meta-analysis was to investigate whether MMP2 (-735C>T) and MMP9 (-1562C>T) SNPs are associated with the risk of RSA. METHODS Literatures published before 17th April 2020 were screened to identify the eligible studies. Heterogeneity, sensitivity and publication bias analysis were analyzed by the STATA software. Odds ratios (ORs) and 95% confidence intervals (CIs) were calculated by the Review Manager software with fixed effects model. RESULTS After screening, 2 studies for MMP2 (-735C>T) (278 RSA cases and 265 controls) and 4 studies for MMP9 (-1562C>T) (520 RSA cases and 512 controls) were enrolled in this meta-analysis. Results showed that MMP2 (-735C>T) presented a statistically significant association with the risk of RSA under allelic (T vs C: OR = 1.50, 95% CI = 1.14-1.98, P = 0.004, I2 = 31%), heterozygote (CT vs CC: OR = 1.74, 95% CI = 1.22-2.50, P = 0.003, I2 = 41%) and dominant (TT + CT vs CC: OR = 1.74, 95% CI = 1.23-2.45, P = 0.002, I2 = 40%) genetic models. MMP9 (-1562C>T) in allelic (T vs C: OR = 1.34, 95% CI = 1.08-1.65, P = 0.007, I2 = 0%), heterozygote (CT vs CC: OR = 1.38, 95% CI = 1.06-1.79, P = 0.02, I2 = 0%) and dominant (TT + CT vs CC: OR = 1.41, 95% CI = 1.10-1.82, P = 0.008, I2 = 0%) genetic models were significantly correlated with the RSA risk. CONCLUSIONS Our meta-analysis results suggest that MMP2 -735T allele and MMP9 -1562T allele have significant association with the risk of RSA.
