Abstract
BACKGROUND The aim of the study was to investigate the role of the genetic variation of glutathione S-transferase M1 (GSTM1) in the development of ovarian endometriosis and endometriosis-related primary infertility risk. METHODS This case-control study included 564 women with ovarian endometriosis and 576 normal women in the control group in northern China. The polymorphism of GSTM1 was genotyped by polymerase chain reaction (PCR)/ligase detection reaction method. To assess the biological significance of polymorphisms, the level of GSTM1 mRNA expression in patients' endometrial tissues with different genotypes was detected by quantitative real-time PCR (qRT-PCR). RESULTS Compared with the positive genotype, the null genotype of GSTM1 was associated with the risk of developing ovarian endometriosis (OR = 1.29, 95% CI = 1.02-1.62). Further analysis showed that patients with a null genotype also had a significantly higher risk of primary infertility than patients with positive genotypes (OR = 1.59, 95% CI = 1.01-2.49). In addition, we found that GSTM1 mRNA expression was present in the endometrial tissue of all patients, but the expression level of patients with a positive genotype was nearly 10 times higher than that of patients with a negative genotype. CONCLUSION Our results suggest that the GSTM1 polymorphism is not only related to the genetic susceptibility to ovarian endometriosis but also a potential molecular marker of primary infertility in patients with ovarian endometriosis.

Abstract
Endometriosis is a pathology form of endometrium that behaves in a similar way to malignancies, such as invasion and resistance to apoptosis. Circular RNAs (CircRNAs) are a class of noncoding RNAs that have several biological functions including, miRNA sponging, sequestering of proteins, enhancing parental gene expression and translation resulting in polypeptides. In this review, we highlighted the roles of circRNAs as potential diagnostic and therapeutic biomarkers in endometriosis. Moreover, we summarized the roles of circRNAs in the pathogenesis of endometriosis via different signaling pathways, such as the miRNA network and apoptosis.

Méar L, Herr M, Fauconnier A, Pineau C, Vialard F. Polymorphisms and endometriosis: a systematic review and meta-analyses. Hum Reprod Update 2020; 26:73-102. [PMID: 31821471 DOI: 10.1093/humupd/dmz034] [Citation(s) in RCA: 33] [Impact Index Per Article: 8.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/10/2019] [Revised: 08/20/2019] [Accepted: 08/28/2019] [Indexed: 12/29/2022] Open
Abstract
BACKGROUND Endometriosis is an estrogen-dependent gynecological disorder that affects at least 10% of women of reproductive age. It may lead to infertility and non-specific symptoms such as chronic pelvic pain. Endometriosis screening and diagnosis are difficult and time-consuming. Late diagnosis (with a delay ranging from 3.3 to 10.7 years) is a major problem and may contribute to disease progression and a worse response to treatment once initiated. Efficient screening tests might reduce this diagnostic delay. As endometriosis is presumed to be a complex disease with several genetic and non-genetic pathogenic factors, many researchers have sought to identify polymorphisms that predispose to this condition. OBJECTIVE AND RATIONALE We performed a systematic review and meta-analysis of the most regularly reported polymorphisms in order to identify those that might predispose to endometriosis and might thus be of value in screening. SEARCH METHODS The MEDLINE database was searched for English-language publications on DNA polymorphisms in endometriosis, with no date restriction. The PubTator text mining tool was used to extract gene names from the selected publications' abstracts. We only selected polymorphisms reported by at least three studies, having applied strict inclusion and exclusion criteria to their control populations. No stratification based on ethnicity was performed. All steps were carried out according to PRISMA guidelines. OUTCOMES The initial selection of 395 publications cited 242 different genes. Sixty-two genes (corresponding to 265 different polymorphisms) were cited at least in three publications. After the application of our other selection criteria (an original case-control study of endometriosis, a reported association between endometriosis and at least one polymorphism, data on women of reproductive age and a diagnosis of endometriosis in the cases established by surgery and/or MRI and confirmed by histology), 28 polymorphisms were eligible for meta-analysis. Only five of the 28 polymorphisms were found to be significantly associated with endometriosis: interferon gamma (IFNG) (CA) repeat, glutathione S-transferase mu 1 (GSTM1) null genotype, glutathione S-transferase pi 1 (GSTP1) rs1695 and wingless-type MMTV integration site family member 4 (WNT4) rs16826658 and rs2235529. Six others showed a significant trend towards an association: progesterone receptor (PGR) PROGINS, interCellular adhesion molecule 1 (ICAM1) rs1799969, aryl-hydrocarbon receptor repressor (AHRR) rs2292596, cytochrome family 17 subfamily A polypeptide 1 (CYP17A1) rs743572, CYP2C19 rs4244285 and peroxisome proliferator-activated receptor gamma (PPARG) rs1801282), and 12 showed a significant trend towards the lack of an association: tumor necrosis factor (TNF) rs1799964, interleukin 6 (IL6) rs1800796, transforming growth factor beta 1 (TGFB1) rs1800469, estrogen receptor 1 (ESR1) rs2234693, PGR rs10895068, FSH receptor (FSHR) rs6166, ICAM1 rs5498, CYP1A1 rs4646903, CYP19A1 rs10046, tumor protein 53 (TP53) rs1042522, X-ray repair complementing defective repair in Chinese hamster cells 1 (XRCC1) rs25487 and serpin peptidase inhibitor clade E member 1 (SERPINE1) rs1799889; however, for the 18 polymorphisms identified in the latter two groups, further studies of the potential association with the endometriosis risk are needed. The remaining five of the 28 polymorphisms were not associated with endometriosis: glutathione S-transferase theta 1 (GSTT1) null genotype, vascular endothelial growth factor alpha (VEGFA) rs699947, rs833061, rs2010963 and rs3025039. WIDER IMPLICATIONS By carefully taking account of how the control populations were defined, we identified polymorphisms that might be candidates for use in endometriosis screening and polymorphisms not associated with endometriosis. This might constitute the first step towards identifying polymorphism combinations that predispose to endometriosis (IFNG (CA) repeat, GSTM1 null genotype, GSTP1 rs1695, WNT4 rs16826658 and WNT4 rs2235529) in a large cohort of patients with well-defined inclusion criteria. In turn, these results might improve the diagnosis of endometriosis in primary care. Lastly, our present findings may enable a better understanding of endometriosis and improve the management of patients with this disease.

Abstract
STUDY QUESTION Is the methylation status of the glutathione S-transferase M1 (GSTM1) promoter region altered in patients with ovarian endometriosis, and does this affect the expression of GSTM1 in their endometrial tissues? SUMMARY ANSWER The promoter region of GSTM1 was significantly hypomethylated in the ectopic and eutopic endometrium of patients with ovarian endometriosis and this was associated with higher expression of GSTM1 mRNA. WHAT IS KNOWN ALREADY GSTM1, a member of the glutathione S-transferase family, is primarily known as a detoxification enzyme, but it has also been shown to negatively regulate apoptosis-related signalling cascades through protein-protein interactions with apoptosis signal-regulating kinase-1. STUDY DESIGN, SIZE, DURATION This is a case-control study between September 2013 and December 2016, involving 65 patients with ovarian endometriosis and 53 women without endometriosis. We analysed the methylation status and expression levels of GSTM1 in the ectopic and eutopic endometrium of patients with ovarian endometriosis and the endometrium of women without endometriosis. In addition, we collected endometrial samples from 12 women without endometriosis for endometrial epithelial cell cultures. PARTICIPANTS/MATERIALS, SETTING, METHODS Methylation levels of the GSTM1 promoter region in the ectopic and eutopic endometrial tissues of patients with ovarian endometriosis and the endometrial tissues of women without endometriosis were analysed by pyrosequencing. The expression of GSTM1 mRNA and protein in endometrial tissues was investigated by RT-qPCR and immunohistochemistry, respectively. Primary cell culture, gene transfection, Cell Counting Kit-8 assay and flow cytometry were used to analyse the effect of GSTM1 on viability and apoptosis in endometrial epithelial cells. MAIN RESULTS AND THE ROLE OF CHANCE Compared with that in the endometrium of women without endometriosis, the GSTM1 promoter region was significantly hypomethylated in the ectopic and eutopic endometrium of patients with ovarian endometriosis. Additionally, GSTM1 mRNA and protein levels were significantly higher in the ectopic and eutopic endometrium than in the control endometrium. Moreover, the methylation levels of the GSTM1 promoter region were significantly negatively correlated with the mRNA expression of GSTM1. Furthermore, in vitro results suggested that the over-expression of GSTM1 could significantly increase viability and inhibit apoptosis in endometrial epithelial cells following hormone treatment and withdrawal. LIMITATIONS, REASONS FOR CAUTION Due to restrictions in the isolation and culture of pure populations of endometrial epithelial cells, as well as limitations in the number of passages possible in primary cells, we could not explore the underlying molecular mechanism by which GSTM1 modulates apoptosis in endometrial cells. WIDER IMPLICATIONS OF THE FINDINGS This study provides new evidence to support the notion that endometriosis may be an epigenetic disease. STUDY FUNDING/COMPETING INTEREST(S) This work was supported by grants from the Natural Science Foundation of Hebei Province (Grant number: H2018206200) and the Department of Education of Hebei Province (Grant number: CXZZBS2017114).

Abstract
OBJECTIVE ESR2 and CYP19A1 genes play a major role in the hormonal control of women with endometriosis. The aim of the study was to analyze single nucleotide polymorphisms (SNPs) in the 3'UTR region of ESR2 and CYP19A1 genes. The study aimed at localisation of new polymorphisms, the nucleotide variants of which determine the level of susceptibility to endometriosis. STUDY DESIGN The study included n = 200 patients: 100 with endometriosis and 100 healthy controls. The Sanger's sequencing method was applied for polymorphism analysis. RESULTS Statistically significant correlations were identified between new, not previously described, two SNPs of ESR2 gene and endometriosis: rs4986938 (G>A) and rs928554 (A>G). In the case of rs4986938 polymorphism, the genotype AA was found to decrease the risk of endometriosis (OR = 0.24 95 % PU 0.05-1.22, p = 0.04). Analysis of the rs928554 polymorphism revealed that the occurrence of the AG genotype reduced the risk of endometriosis (OR = 0.38 95 % PU 0.21-0.71, p = 0.002). There were no differences in the distribution of genotypes of the polymorphisms rs10046 (C>T) and rs4646 (C>A) of CYP19A1 gene between patients and control. CONCLUSIONS Further studies are necessary in groups with higher numbers of patients to explain whether the above-mentioned polymorphisms may be the risk factors for endometriosis.

Abstract
AIM Circular RNAs (circRNAs) with miRNA response elements (MREs) could function as competing endogenous RNA (ceRNA) in regulating gene expression. This study was carried out to identify the expression profile and role of circRNAs in endometriosis. MATERIALS & METHODS Microarray assay was performed in four paired ovarian endometriomas and eutopic endometrium, followed by quantitative real-time RT-PCR in 24 paired samples. Bioinformatical algorithms were used to predict MREs, as well as ceRNA and KEGG pathway analysis. RESULTS We identified 262 upregulated and 291 downregulated circRNAs, binding with 1225 MREs. The ceRNA network included 122 miRNAs and 137 mRNAs, which are involed in nine pathways. CONCLUSION CircRNAs are differentially expressed in endometriosis, which might be related with pathogenesis of endometriosis.
