Abstract
Having genetically related offspring remains an unattainable dream for couples with reproductive failure. Mesenchymal stem cells (MSCs) are multipotent stromal cells derived from various human tissues and organs. As critical paracrine effectors of MSCs, extracellular vesicles (EVs) can carry and deliver bioactive content, thereby participating in intercellular communication and determining cell fate. Mesenchymal stem cell-derived extracellular vesicles (MSC-EVs) have shown promising therapeutic effects, including repairing injured endometria, restoration of ovarian functions, and improving sperm quantity, morphology, and motility, owing to their regenerative potential, abundant sources, high proliferation rates, low immunogenicity, and lack of ethical issues. However, limited knowledge on purification and isolation of MSC-EVs, therapeutic effects, and unpredictable safety have caused challenges in overcoming female and male infertility. To overcome them, future studies should focus on modification/engineering of MSC-EVs with therapeutic biomolecules and combining attractive biomaterials and MSC-EVs. This review highlights the latest studies on MSC-EVs therapies in infertility and the major challenges that must be overcome before clinical translation.

Association between KRAS and PIK3CA Mutations and Progesterone Resistance in Endometriotic Epithelial Cell Line. Curr Issues Mol Biol 2024; 46:3579-3594. [PMID: 38666954 PMCID: PMC11049223 DOI: 10.3390/cimb46040224] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/20/2024] [Revised: 04/16/2024] [Accepted: 04/17/2024] [Indexed: 04/28/2024] Open
Abstract
Although endometriosis is a benign disease, it is associated with cancer-related gene mutations, such as KRAS or PIK3CA. Endometriosis is associated with elevated levels of inflammatory factors that cause severe pain. In a previous study, we demonstrated that KRAS or PIK3CA mutations are associated with the activation of cell proliferation, migration, and invasion in a patient-derived immortalized endometriotic cell line, HMOsisEC10. In this study, we investigated the effects of these mutations on progesterone resistance. Since the HMOsisEC10 had suppressed progesterone receptor (PR) expression, we transduced PR-B to HMOsisEc10 cell lines including KRAS mutant and PIK3CA mutant cell lines. We conducted a migration assay, invasion assay, and MTT assay using dienogest and medroxyprogestrone acetate. All cell lines showed progesterone sensitivity with or without mutations. Regarding inflammatory factors, real-time quantitative RT-PCR revealed that the KRAS mutation cell line exhibited no suppression of Cox-2 and mPGES-1 on progesterone treatment, whereas IL-6, MCP-1, VEGF, and CYP19A1 were significantly suppressed by progesterone in both mutated cell lines. Our results suggest that KRAS mutation and PIK3CA mutation in endometriotic cells may not be associated with progesterone resistance in terms of aggressiveness. However, KRAS mutations may be associated with progesterone resistance in the context of pain.

Abstract
Early gestational loss occurs in approximately 20% of all clinically recognized human pregnancies and is an important cause of morbidity. Either embryonic or maternal defects can cause loss, but a functioning and receptive uterine endometrium is crucial for embryo implantation. We report that the switch/sucrose nonfermentable (SWI/SNF) remodeling complex containing polybromo-1 (PBRM1) and Brahma-related gene 1 (BRG1) is essential for implantation of the embryonic blastocyst on the wall of the uterus in mice. Although preimplantation development is unaffected, conditional ablation of Pbrm1 in uterine stromal cells disrupts progesterone pathways and uterine receptivity. Heart and neural crest derivatives expressed 2 (Hand2) encodes a basic helix-loop-helix (bHLH) transcription factor required for embryo implantation. We identify an enhancer of the Hand2 gene in stromal cells that requires PBRM1 for epigenetic histone modifications/coactivator recruitment and looping with the promoter. In Pbrm1cKO mice, perturbation of chromatin assembly at the promoter and enhancer sites compromises Hand2 transcription, adversely affects fibroblast growth factor signaling pathways, prevents normal stromal-epithelial crosstalk, and disrupts embryo implantation. The mutant female mice are infertile and provide insight into potential causes of early pregnancy loss in humans.

Abstract
BACKGROUND In the most severe stage of endometriosis, Stage IV, intestinal involvement is common. The true prevalence of endometriotic disease of the appendix in this population is not well described. A macroscopically normal looking appendix may harbour endometriosis. AIMS Our study aims to assess the role of routinely performing appendicectomy in Stage IV endometriosis surgery, and the histopathological prevalence of true appendiceal endometriosis in this population. METHODS This is a retrospective study of women undergoing surgery for Stage IV endometriosis between 2018 to 2022 in a tertiary public hospital in New South Wales, Australia. Patient demographics, age and post-operative complications were retrospectively retrieved from hospital medical records. Inclusion criteria were women with Stage IV endometriosis who underwent routine appendicectomy as part of their endometriosis surgery. Exclusion criteria were women who did not have Stage IV endometriosis, those who had cancer surgery or emergency surgery for endometriosis. The primary outcome of this study was to determine the incidence of appendiceal endometriosis. Secondary outcomes included post-operative complications and length of stay. RESULTS Sixty-seven patients were included. The mean age was 36 years. All patients also underwent bowel resection for colorectal endometriosis. There were 35.8% who had confirmed appendiceal endometriosis on histopathology. Post-operative complications included port site infections, colitis, urinary tract infection and ureteric injury. There were no complications related to appendicectomy. Mean length of stay was 4.4 days. CONCLUSION Laparoscopic appendicectomy can be safely performed at time of laparoscopic surgical excision of Stage IV endometriosis and should be routinely considered in a subset of Stage IV endometriosis patients with colorectal involvement undergoing surgery.

Abstract
The endometrium is a unique human tissue with an extraordinary ability to undergo a hormone-regulated cycle encompassing shedding, bleeding, scarless repair, and regeneration throughout the female reproductive cycle. The cyclical repair and regeneration of the endometrium manifest as changes in endometrial epithelialization, glandular regeneration, and vascularization. The mechanisms encompass inflammation, coagulation, and fibrinolytic system balance. However, specific conditions such as endometriosis or TCRA treatment can disrupt the process of cyclical endometrial repair and regeneration. There is uncertainty about traditional clinical treatments' efficacy and side effects, and finding new therapeutic interventions is essential. Researchers have made substantial progress in the perspective of regenerative medicine toward maintaining cyclical endometrial repair and regeneration in recent years. Such progress encompasses the integration of biomaterials, tissue-engineered scaffolds, stem cell therapies, and 3D printing. This review analyzes the mechanisms, diseases, and interventions associated with cyclical endometrial repair and regeneration. The review discusses the advantages and disadvantages of the regenerative interventions currently employed in clinical practice. Additionally, it highlights the significant advantages of regenerative medicine in this domain. Finally, we review stem cells and biologics among the available interventions in regenerative medicine, providing insights into future therapeutic strategies.

Abstract
Ultrasensitive identification of biomarkers in biofluids is essential for the precise diagnosis of diseases. For the gold standard approaches, polymerase chain reaction and enzyme-linked immunosorbent assay, cumbersome operational steps hinder their point-of-care applications. Here, a bionic biomarker entrapment system (BioES) is implemented, which employs a multi-body Y-shaped tetrahedral DNA probe immobilized on carbon nanotube transistors. Clinical identification of endometriosis is successfully realized by detecting an estrogen receptor, ERβ, from the lesion tissue of endometriosis patients and establishing a standard diagnosis procedure. The multi-body Y-shaped BioES achieves a theoretical limit of detection (LoD) of 6.74 aM and a limit of quantification of 141 aM in a complex protein milieu. Furthermore, the BioES is optimized into a multi-site recognition module for enhanced binding efficiency, realizing the first identification of monkeypox virus antigen A35R and unamplified detection of circulating tumor DNA of breast cancer in serum. The rigid and compact probe framework with synergy effect enables the BioES to target A35R and DNA with a LoD down to 991 and 0.21 aM, respectively. Owing to its versatility for proteins and nucleic acids as well as ease of manipulation and ultra-sensitivity, the BioES can be leveraged as an all-encompassing tool for population-wide screening of epidemics and clinical disease diagnosis.

Abstract
Catamenial pneumothorax is one of the most common extra-pelvic presentations of endometriosis, with the gastrointestinal tract being the most common location. Catamenial pneumothorax is defined as spontaneous recurrent pneumothorax occurring in women of reproductive age in a temporal relationship with menses. Symptoms include dyspnea, sharp chest pain, and hypoxemia. A much rarer presentation is the involvement of endometriosis with the diaphragm. In this case, we present a 31-year-old female who presented with signs of pneumothorax. She has had multiple episodes leading to suspicion of catamenial pneumothorax. However, it wasn't until her surgery that the extent of diaphragmatic involvement, characterized by numerous holes secondary to endometriosis, was discovered. She was surgically treated, which led to a drastic improvement in symptoms and a reduction in subsequent episodes. We hope that this case can add to the current limited literature on diaphragmatic endometriosis cases. Since this patient presented with mainly catamenial pneumothorax symptoms, we urge clinicians to still consider diaphragmatic involvement as a primary cause in patients with recurrent episodes of pneumothorax.

Abstract
Endometriosis is a chronic inflammatory estrogen-dependent disease characterized by the growth of endometrial-like tissue outside the physiological region. Despite the fact that this disease is common, laparoscopic surgery is currently the gold standard in the treatment of endometriosis. In this regard, it is necessary to develop new effective methods of minimally invasive therapy for endometriosis. One of the promising areas in the treatment of endometriosis is cell therapy. Cellular therapy is a vast branch of therapeutic methods with various agents. Potential cell therapies for endometriosis may be based on the principle of targeting aspects of the pathogenesis of the disease: suppression of estrogen receptor activity, angiogenesis, fibrosis, and a decrease in the content of stem cells in endometriosis foci. In addition, immune cells such as NK cells and macrophages may be promising agents for cell therapy of endometriosis. Standing apart in the methods of cell therapy is the replacement therapy of endometriosis. Thus, many studies in the field of the pathogenesis of endometriosis can shed light not only on the causes of the disease and may contribute to the development of new methods for personalized cell therapy of endometriosis.

Abstract
Endometriosis is an estrogen-dependent gynecologic illness that has long-term effects on a woman’s fertility, physical health, and overall quality of life. Growing evidence suggests that endocrine-disrupting chemicals (EDCs) may be etiologically involved in the development and severity of the disease. We consider the available human evidence on EDCs and endometriosis, limiting ourselves to studies that have individually assessed chemical amounts in women. Dioxins, BPA, Phthalates, and other endocrine disruptors, like DDT, are among the evidence indicating an environmental etiology for endometriosis. Collectively, this review describes how environmental toxins are linked to lower fertility in women, as well as a number of reproductive diseases, focusing on the pathology of endometriosis and its treatments. Importantly, this review can be used to investigate techniques for preventing the negative effects of EDC exposure.

Abstract
Background and Aims: Chronic pelvic pain (CPP) is a persistent pelvic pain that
leads to reduced work performance and impaired quality of life in females. Nearly
15% of females report time off from paid work and around 45% report reduced
work productivity. There is a paucity of studies to address the issue, especially
with a multidisciplinary and multifactorial view. Various gynaecological disorders
are associated with CPP such as endometriosis, adenomyosis, adhesions, chronic
pelvic inflammatory disease, and pelvic congestion syndrome. The objective is
to determine the frequency of CPP in females attending gynaecologic outpatient
departments.
Materials and Methods: A total of 201 patients aged 14–48 years attending the
gynaecologic outpatient department for gynaecological disorders with complaints
of lower abdominal pain were included in this study. Patients enrolled in the study
were assessed by a detailed history and pelvic examination, and a structured
questionnaire was filled out. Data were analysed using the statistical package for
social sciences version 23.0 (International Business Machines Corporation, Armonk,
New York, USA).
Results: The mean age of the patients was 32.39±6.98 years. The frequency of CPP
in females was observed as 95.52% (95% confidence interval: 91.67–97.93%) The
rate of CPP was significantly high in females with parity ≤5 and those who had a
duration of pain lower than 36 months. In multivariate analysis, adjusted odds ratio
by stepwise logistic regression model showed that parity (parity 0–1) and duration of
pain (≤36 months) were significantly associated with CPP in females.
Conclusion: The study indicates that the most common gynaecological causes of
CPP in females attending the outpatient department were those with endometriosis
followed by adenomyosis. The management of CPP needs patient-centred care with
a multidisciplinary approach. This will lead to early and effective management.

Abstract
PROBLEM Endometriosis is a proliferative disease characterized by cytokine-induced inflammation. The objective of this study was to assess cell growth and PGE2 production induced by TNF-α in endometriotic stromal cells (ESCs) in spheroid cell culture and to identify the signaling pathway involved with a view to finding new therapeutic targets for endometriosis. METHOD OF STUDY Tissue samples were collected from patients with and without endometriosis. ESCs were isolated from ovarian endometrioma (OE). Gene expression was evaluated by real-time PCR and DNA microarray analysis, the proliferative effect on ESCs by WST-8 assay, and PGE2 production by ELISA. Protein phosphorylation was detected using western blotting. RESULTS COX-2, aromatase and VEGFA mRNA expression and PGE2 production were significantly elevated in spheroid cell cultures compared to monolayer cell cultures. TNF-α receptor (TNFR) 1 and TNFR2 mRNA was also significantly increased. TNF-α promoted the proliferation and PGE2 production of ESCs in spheroid cell cultures significantly more than in monolayer cell cultures. TNF-α increased the expression of several genes related to the pathophysiology of endometriosis in spheroid ESCs. DNA microarray analysis revealed that the Tpl2 gene, which codes for a MAPK upstream of MEK, was upregulated in OE and endometrium with endometriosis compared to normal endometrium. TNF-α increased the phosphorylation and expression of Tpl2 and MEK, and Tpl2 and MEK inhibitors inhibited TNF-α-induced proliferation and PGE2 production in spheroid ESCs. CONCLUSION The Tpl2-MEK signaling pathway may play a critical role in the cell growth and PGE2 production induced by TNF-α in spheroid ESCs.

Prevalence and Risk Factors of Central Sensitization in Women with Endometriosis. J Minim Invasive Gynecol 2023; 30:73-80.e1. [PMID: 36441085 DOI: 10.1016/j.jmig.2022.10.007] [Citation(s) in RCA: 9] [Impact Index Per Article: 9.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/16/2022] [Revised: 10/21/2022] [Accepted: 10/24/2022] [Indexed: 11/05/2022]
Abstract
STUDY OBJECTIVE To assess prevalence of central sensitization (CS) and its association with demographic and clinical factors in patients with endometriosis. DESIGN Single-center, observational, cross-sectional study. SETTING Tertiary center. PATIENTS Consecutive patients with endometriosis referred to the center from January 15, 2022, to April 30, 2022. INTERVENTIONS For each enrolled patient, demographic and clinical data were collected, and the presence of CS was measured using the CS Inventory questionnaire (score ≥40). MEASUREMENTS AND MAIN RESULTS Primary study outcome was CS prevalence, and secondary study outcomes were the associations between demographic and clinical factors and CS. The 95% confidence intervals for CS prevalence were obtained with Bayesian-derived Jeffreys method, and the associations between CS and demographic and clinical factors were evaluated with the chi-square test and Fisher's exact test, where appropriate. The variables significantly associated with CS were then included in a multivariable logistic regression model. The significance level was set at .05 for all analyses. During the study period, 285 eligible women were enrolled. CS prevalence was 41.4% (95% confidence interval, 35.8-47.2). At univariable analysis, infertility, moderate to severe pain symptoms (except for dyschezia), altered bowel movements, posterolateral parametrium involvement, hormonal therapy failure (HTF), and most of central sensitivity syndromes were significantly associated with CS occurrence. Multivariable analysis only confirmed the significant association of CS with moderate to severe chronic pelvic pain, posterolateral parametrium involvement, HTF, migraine or tension-type headache, irritable bowel syndrome, and anxiety or panic attacks. CONCLUSION CS has a high prevalence in patients with endometriosis, especially in those with moderate to severe chronic pelvic pain, posterolateral parametrium involvement, HTF, and 3 central sensitivity syndromes (i.e. migraine or tension-type headache, irritable bowel syndrome, anxiety or panic attacks). Given the association with HTF, identifying CS through CS Inventory might be useful to counsel the patient and to choose multimodal treatment.

Abstract
BACKGROUND The incidence of endometriosis (EMs), a common disease in gynecology, has increased over the years. Women suffer from the symptoms caused by EMs, such as chronic pelvic pain, dysmenorrhea, and infertility. However, the etiology and pathophysiology of EMs remain unclear. This study aimed to identify candidate genes of endometriosis through integrated analysis of genome-wide gene expression and DNA methylation profiles. RESULTS Eutopic and ectopic endometrial tissues were collected from patients who were diagnosed as ovarian EMs. Genome-wide methylation profiling identified 17551 differentially methylated loci, with 9777 hypermethylated and 7774 hypomethylated loci. Differentially methylated loci were mainly concentrated in the gene body and intergenic regions. Genome-wide gene expression profiling identified 1837 differentially expressed genes (DEGs), with 1079 genes upregulated and 758 downregulated in ectopic groups. Integrated analysis revealed that DNA methylation was negatively correlated to gene expression in most genomic regions, such as exon, 3'UTR, 5'UTR, and promoter. We also identified promoter-related (53 downregulated and 113 upregulated) and enhancer-related DMGs (212 downregulated and 232 upregulated), which were significantly correlated to the gene expression. Further validation of the top-ranked genes belonging to differentially methylated genes (DMGs) and DEGs revealed that TMEM184A, GREM2, SFN, KIR3DX1, HPGD, ESR1, BST2, PIK3CG and RNASE1 were significant candidate genes in ovarian endometriosis. CONCLUSION Our study revealed the significance of DNA methylation in the gene expression in ovary endometriosis, which provides new insights and a molecular foundation for understanding the underlying mechanisms of endometriosis.

Abstract
Objectives The objective of this study was to assess the potential risk factors for abscess development in patients with endometrioma who present with an acute abdomen. Materials and Methods We retrospectively reviewed the records of 51 patients who underwent emergency surgery for acute abdomen involving an endometrioma at our hospital between April 2011 and August 2021. The patients were divided into an infected group (n = 22) and a control group (n = 29). We analyzed patient characteristics; imaging findings; clinical data, including bacterial cultures; and perioperative outcomes to assess for differences between groups. Results Patients in the infected group were significantly older than those in the control group (P = 0.03). They were more likely to have a history of endometriosis surgery (P = 0.04) and more likely to have undergone transvaginal manipulation within 3 months of presentation (P = 0.01). Body temperature on the day of admission was significantly higher in the infected group (P = 0.007), as were C-reactive protein levels on the day of admission and before surgery (P < 0.001; P = 0.018) and the white blood cell count on the day of admission (P = 0.016). Preoperative imaging showed significant thickening of the tumor wall (P < 0.001) and an enhanced contrast effect (P < 0.001) in the infected group. Conclusion We identified several factors that suggest abscess in patients with an acute abdomen who have a complication of pathologically confirmed endometriosis. A recent vaginal procedure is a particular risk factor for abscess development in patients with endometriomas.

Is hormonal manipulation after surgical treatment of catamenial pneumothorax effective in reducing the rate of recurrence? A systematic review and meta-analysis. Eur J Obstet Gynecol Reprod Biol 2022; 278:141-147. [PMID: 36179536 DOI: 10.1016/j.ejogrb.2022.09.019] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/28/2022] [Revised: 09/02/2022] [Accepted: 09/18/2022] [Indexed: 11/28/2022]
Abstract
OBJECTIVES Catamenial pneumothorax CP is a rare form of spontaneous pneumothorax in females forming part of thoracic endometriosis syndrome. Studies have suggested possible benefit from postoperative hormonal administration. As this treatment is inconsistent, we aimed at performing the first meta-analysis to study the efficacy of adding hormonal treatment after surgery to reduce the chances of recurrent catamenial pneumothorax. METHODS CENTRAL, MEDLINE/PubMed, Cochrane Library, and Scopus were systematically searched from inception up to December 15, 2021. Studies reporting five or more patients with end point outcome were included. The main outcome assessed was postoperative recurrence of CP after hormonal manipulation. Baseline, procedural, outcome, and validity data were systematically appraised and pooled with random-effect methods. meta- regression for the effect of patient age and follow up period were tested. Publication bias was examined. This trial was registered with PROSPERO under registration number CRD42022325377. RESULTS Our electronic search retrieved 644 citations, 48 of which were selected for full-text review. Eleven studies with a combined population of 111 patients fulfilled the inclusion criteria. All patients reached an endpoint of follow up for postoperative recurrence of catamenial pneumothorax after receiving hormonal treatment. Overall study validity was acceptable, with a median score of 6 on the Newcastle Ottawa scale NOS appraising the quality of observational studies. CP is almost always a right-side disease (107/111 = 96.3 %). The risk of postoperative recurrence with hormonal treatment was 17.3 % (8.9 - 25.8 %) with moderate non-significant heterogeneity (I2 = 40.85 %; P = 0.076). The cumulative risk of recurrence for all patients not receiving postoperative hormonal therapy included in our study was 54.2 % (19/35 patients). Meta regression showed age to be a significant predictor of postoperative recurrence (p = 0.03). As the age increases one year, the risk of recurrence decreases by 6 % (0.2 - 3 %). Publication bias was detected by visualizing the funnel plot of standard error, Egger's test with p < 0.01 and Begg & Mazumdar test with p < 0.01. CONCLUSION The study included the largest number of CP patients with outcome findings of postoperative recurrence with hormonal treatment despite the small number of studies, non-randomised fashion and publication bias. Our findings recommend the use of hormonal manipulation after thoracic surgical intervention for catamenial pneumothorax unless evident contraindications. Younger patients are at a higher risk of recurrence after surgery.

Abstract
This study aimed to assess the relationship between placenta accreta spectrum disorder (PASD) and endometriosis. The relationships among pregnancy, assisted reproductive technology (ART), placenta previa, ART-conceived pregnancy and PASD were also determined. A systematic literature review was conducted using multiple computerized databases. Forty-eight studies (1990–2021) met the inclusion criteria. According to the adjusted pooled analysis (n = 3), endometriosis was associated with an increased prevalence of PASD (adjusted odds ratio [OR] 3.39, 95% confidence interval [CI] 1.96–5.87). In the included studies, the ART rate ranged from 18.2% to 37.2% for women with endometriosis. According to the adjusted pooled analysis, women who used ART were more likely to have placenta previa (n = 13: adjusted OR 2.96, 95%CI, 2.43–3.60) and PASD (n = 4: adjusted OR 3.54, 95%CI 1.86–6.76) than those who did not use ART. According to the sensitivity analysis using an unadjusted analysis accounting for the type of ART, frozen embryo transfer (ET) was associated with an increased risk of PASD (n = 4: OR 2.79, 95%CI, 1.22−6.37) compared to fresh ET. Endometriosis may be associated with an increased rate of PASD. Women with placenta previa complicated with endometriosis who conceived using frozen ET may be a high risk for PASD.

Abstract
Endometriosis (EM) is an estrogen-dependent disease characterized by the presence of epithelial, stromal, and smooth muscle cells outside the uterine cavity. It is a chronic and debilitating condition affecting ~10% of women. EM is characterized by infertility and pain, such as dysmenorrhea, chronic pelvic pain, dyspareunia, dysuria, and dyschezia. Although EM was first described in 1860, its aetiology and pathogenesis remain uncertain. Recent evidence demonstrates that the peripheral nervous system plays an important role in the pathophysiology of this disease. Sensory nerves, which surround and innervate endometriotic lesions, not only drive the chronic and debilitating pain associated with EM but also contribute to a growth phenotype by secreting neurotrophic factors and interacting with surrounding immune cells. Here we review the role that peripheral nerves play in driving and maintaining endometriotic lesions. A better understanding of the role of this system, as well as its interactions with immune cells, will unearth novel disease-relevant pathways and targets, providing new therapeutics and better-tailored treatment options.

Abstract
Endometriosis is defined as the presence of endometrial tissue outside the uterine cavity. It is a common finding in premenopausal women and commonly affects the gastrointestinal tract, especially the rectosigmoid tract. Small bowel involvement is rare and usually asymptomatic making diagnosis difficult. Here we report an uncommon case of exophytic ileal endometriosis surgically treated. Detailed pre-operative counselling on the risk of ileal surgery should always be considered in all cases with endometriosis requiring surgery. We also present a review of the literature regarding the clinical presentation, diagnosis, and treatment of this challenging condition.

Abstract
OBJECTIVE To compare the efficacy of dienogest with the combined oral contraceptive pill (COC) Yasmin for the control of endometriosis-associated pelvic pain. STUDY DESIGN Seventy women with endometriosis-associated chronic pelvic pain, dysmenorrhoea or both for >6 months were randomized to either dienogest (Visanne) 2 mg/day or monophasic COC (Yasmin, 0.03 mg ethinyl estradiol and 3 mg drospirenone) for 24 weeks. The primary efficacy variable was change in non-cyclic pelvic pain and dysmenorrhoea from baseline to end of treatment, assessed using a visual analogue scale (VAS). The secondary efficacy variable was change in the Biberoglu and Behrman (B&B) scale scores for chronic pelvic pain, dysmenorrhoea and dyspareunia. Health-related quality of life (HRQoL) was evaluated using the Endometriosis Health Profile-30 (EHP-30) questionnaire at baseline and 24 weeks. Safety variables included incidence of side-effects, bleeding pattern and treatment tolerability. RESULTS Both treatments improved the mean VAS score for endometriosis-associated pelvic pain significantly: mean difference 6.0 [95% confidence interval (CI) 4.9-7.1; p < 0.0001] in the dienogest group and 4.54 (95% CI 3.1-5.9; p < 0.0001) in the COC group; the difference between them was not significant (p = 0.111). Similarly, both dienogest and COC improved HRQoL in various core and modular segments of the EHP-30 questionnaire with comparable requirements for supplemental pain medication (p = 0.782 and 0.258 at 12 and 24 weeks, respectively), and redistribution of the B&B severity profile for chronic pelvic pain (p = 0.052 and 0.526 at 12 and 24 weeks, respectively), dysmenorrhoea (p = 0.521 and 1 at 12 and 24 weeks, respectively) and dyspareunia (p = 0.376 and 0.835, respectively). Nevertheless, dienogest was associated with fewer side-effects, and hence had a better safety and tolerability profile than COC. CONCLUSIONS Dienogest (2 mg/day) is comparable to the COC Yasmin for the relief of endometriosis-associated pelvic pain and improvement in HRQoL. CLINICAL TRIAL REGISTRATION Clinicaltrials.gov under number NCT04256200; date of registration 15/1/2020 (registered retrospectively).

Bulut E, Peker M, Kupeli A, Danisan G, Bulut AC. The efficiency of susceptibility-weighted MRI in the differentiation of endometriomas from haemorrhagic ovarian cysts. Abdom Radiol (NY) 2021; 46:5337-5343. [PMID: 34313828 DOI: 10.1007/s00261-021-03196-4] [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: 04/18/2021] [Revised: 06/22/2021] [Accepted: 06/23/2021] [Indexed: 10/20/2022]
Abstract
OBJECTIVES The aim of the study was to investigate the efficiency of susceptibility-weighted magnetic resonance (MR) imaging (SWIs) in differentiating endometriomas from haemorrhagic ovarian cysts. MATERIALS AND METHODS Between July 2017 and January 2019, 89 ovarian cystic lesions (57 endometriomas and 32 haemorrhagic cysts) that were identified as complicated cystic lesions on ultrasonography (US) and underwent lower abdominal MRI with susceptibility weighting were retrospectively evaluated. Final diagnoses were obtained with surgical pathological correlation and radiological-clinical follow-up. Two radiologists blinded to the final diagnoses retrospectively reviewed the images in consensus. The signal intensity on T1- and T2-weighted images and curved linear or punctate signal void areas on SWI were noted for the presence of lesions. RESULTS Forty of the 57 endometriomas demonstrated the defined MRI criteria, including a cystic hyperintensity on T1-weighted images and hypointensity on T2-weighted images. The remaining 17 lesions did not demonstrate these criteria on conventional MR images. SWI showed punctate or curved linear signal void areas in 53 of 57 endometriomas (92.9%) and none of the haemorrhagic cysts. The sensitivity, specificity and accuracy of SWI in differentiating endometrioma from haemorrhagic cyst were 92.9%, 100.0%, and 95.5%, respectively. CONCLUSIONS The addition of the SWI sequence to conventional MRI can help distinguish endometriomas from haemorrhagic ovarian cysts.

Abstract
Aim: To determine the outcomes of laparoscopic partial cystectomy (LPC) for bladder endometriosis (BE). Methods: This was a retrospective study using medical records of women who underwent LPC for BE between January 2009 and December 2017. Demographic characteristics, surgical findings, including surgical site and size of the bladder lesion, endometriosis at other locations, and pre- and postoperative hormonal treatment data were collected. Results: We analyzed data of 18 women with full-thickness BE. The patients had a mean age of 34 (range, 26–45) years and body mass index of 21.6 (range, 16.1–25) kg/m2. All women had dysmenorrhea. Other symptoms noted include dysuria, gross hematuria, and infertility. BE with a mean diameter of 2.7 cm (range, 1–5) was most commonly found at the posterior wall of the bladder (94.4%). Peritoneal endometriosis (94.4%), endometrioma (33.3%), and deep endometriotic nodules (22.2%) in the posterior compartment were also found. No surgical complications were observed. Postoperative hormonal treatment was administered to 14 (77.8%) patients. All symptoms improved after the surgery. No recurrence was found after 30 (range, 12–74) months of follow-up. Conclusion: LPC is an effective treatment option for BE.

Abstract
Endometriosis is a chronic disorder characterized by the presence of endometrial glands and stroma outside the uterine cavity. It affects 8%-10% of women in their reproductive years, and represents a major clinical problem with deleterious social, sexual and reproductive consequences. Current treatment options include pain relief, hormonal intervention and surgical removal. However, these treatments are deemed unsatisfactory owing to varying success, significant side effects and high recurrence rates. Green tea and its major bioactive component, (-)-epigallocatechin gallate (EGCG), possess diverse biological properties, particularly anti-angiogenic, anti-proliferation, anti-metastasis, and apoptosis induction. In recent years, preclinical studies have proposed the use of green tea to inhibit the growth of endometriosis. Herein, the aim of this review is to summarize the potential therapeutic effects of green tea on molecular and cellular mechanism through inflammation, oxidative stress, invasion and adhesion, apoptosis and angiogenesis in endometriosis.

Accuracy of Transvaginal Ultrasound Compared to Cystoscopy in the Diagnosis of Bladder Endometriosis Nodules. JOURNAL OF ULTRASOUND IN MEDICINE : OFFICIAL JOURNAL OF THE AMERICAN INSTITUTE OF ULTRASOUND IN MEDICINE 2021; 40:1571-1578.

Abstract
OBJECTIVES To evaluate the accuracy of transvaginal ultrasound (TVUS) in predicting detrusor infiltration and ureteral meatus involvement in patients with bladder endometriosis (BE) to select which cystoscopic procedures could be avoided and, secondarily, to assess the relationship between symptoms and the characteristics of nodules and the association of BE with other forms of endometriosis. METHODS Patients with BE diagnosed by TVUS were classified according to detrusor infiltration: BE with partial involvement of the muscular layer (group 1) and total muscular layer involvement with bladder protrusion (group 2). We analyzed the accuracy of TVUS compared with subsequently performed cystoscopy, the correlation with symptoms, and the association with other forms of endometriosis. RESULTS Among the 22 patients included, TVUS showed 9 patients with BE nodules partially affecting the detrusor (group 1) with normal cystoscopic findings (TVUS negative predictive value, 100%). Transvaginal ultrasound detected 13 nodules with total involvement, all visible by cystoscopy (TVUS positive predictive value, 100%). Transvaginal ultrasound also identified ureteral orifices that were free of involvement at greater than 10 mm from the BE nodule in 21 of 22 women (TVUS sensitivity, 95%). Ultrasound criteria for adenomyosis and endometriosis in other locations were present in 20 of 22 patients. CONCLUSIONS Transvaginal ultrasound can identify the infiltration of BE nodules in the bladder wall and predict cystoscopic findings with great accuracy. Nodules that partially affect the muscular layer have normal cystoscopic findings, thereby obviating the need for this procedure. Bladder endometriosis nodules are commonly associated with other forms of endometriosis and do not usually affect the ureteral meatus.

Abstract
Simple Summary Endometriosis is a common gynecological condition that causes pelvic pain and infertility. Despite having normal histological features, several cells bear cancer-associated somatic mutations that result in local tissue invasion but rarely metastasize. Several cancer-associated genes, such as KRAS and PIK3CA, are frequently mutated in the endometriotic epithelium. However, the functional behavior and molecular pathogenesis of this disorder remain unclear. In this study, we developed an immortalized endometriotic epithelial cell line with mutations in KRAS and PIK3CA, which are genes associated with aggressive behaviors, such as increased cell migration, invasion, and proliferation. Through microarray analysis, the KRAS- and PIK3CA-specific gene signatures were identified; LOX and PTX3 were found to be responsible for this metastatic behavior. Knockdown of these two genes by siRNA markedly reduced the metastatic ability of the cells. Our findings suggest that inhibition of LOX and PTX3 may be an alternative therapeutic strategy to reduce the incidence of endometriosis. Abstract Endometriosis-harboring cancer-associated somatic mutations of PIK3CA and KRAS provides new opportunities for studying the multistep processes responsible for the functional and molecular changes in this disease. We aimed to establish a novel in vitro endometriosis model to clarify the functional behavior and molecular pathogenesis of this disorder. Immortalized HMOsisEC10 human ovarian endometriotic epithelial cell line was used in which KRAS and PIK3CA mutations were introduced. Migration, invasion, proliferation, and microarray analyses were performed using KRAS and PIK3CA mutant cell lines. In vitro assays showed that migration, invasion, and proliferation were significantly increased in KRAS and PIK3CA mutant cell lines, indicating that these mutations played causative roles in the aggressive behavior of endometriosis. Microarray analysis identified a cluster of gene signatures; among them, two significantly upregulated cancer-related genes, lysyl oxidase (LOX) and pentraxin3 (PTX3), were associated with cell proliferation, invasion, and migration capabilities. Furthermore, siRNA knockdown of the two genes markedly reduced the metastatic ability of the cells. These results suggest that endometriosis with KRAS or PIK3CA mutations can significantly enhance cell migration, invasion, and proliferation by upregulating LOX and PTX3. We propose that LOX and PTX3 silencing using small molecules could be an alternative therapeutic regimen for severe endometriosis.

Abstract
The vitamin D receptor (VDR) and aryl hydrocarbon receptor (AHR) are two nuclear receptors that exert their effects by binding with ligands and forming a molecular complex. These complexes translocate to the nucleus and activate the expression of a series of genes which have a response element to VDR or AHR. Both receptors have been identified in the pathogenesis of endometriosis, a common disease characterized by the formation of endometrium-like tissue in ectopic zones. Despite numerous therapies, there is no definitive cure for endometriosis at the pharmacological level. Our study aims to describe the location and the expression of VDR and AHR at the protein level. For this purpose, an evaluation was performed using tissue from the three normal phases of the endometrium (proliferative, early, and late secretory) and in endometriosis by immunohistochemistry, using anti-VDR and anti-AHR antibodies. We demonstrate that in the nuclei of glandular cells in endometriosis, the expression of VDR and AHR is mutually exclusive—when the expression of one receptor is high, the other one is low—suggesting a possible target in the treatment of endometriosis. We also identify a significant change in the expression of glandular cytoplasmic AHR between the proliferative and late secretory endometrium.

Abstract
INTRODUCTION Surgical management of Diaphragmatic and thoracic endometriosis (DTE) is still controversial, a thoracic or an abdominal approach can be proposed. METHODS We conducted a multicentric retrospective study in 8 thoracic, gynecology or digestive surgery units in 5 French university hospitals. The main objective was to review the current management of DTE. RESULTS 50 patients operated for DTE from 2010 to 2017 were included: 26 with a thoracic approach and 24 with an abdominal approach. Preoperative pelvic endometriosis (PE) concerned 25 patients. In 38 patients, DTE diagnosis was made on clinical symptoms (pneumothorax (n = 19), chronic or catamenial chest pain (n = 18) or hemopneumothorax (n = 1)). Median time from onset of symptoms to diagnosis was 47 months (0-212). PE surgery concurrently occurred in 22 patients. We report diaphragmatic nodules, pleuropulmonary nodules and diaphragmatic perforations in 42, 5 and 22 women respectively. Lesions were right-sided in 45 patients. Nodules were destructed in 12 cases and resected in 38 cases. When a diaphragmatic reconstruction was needed (n = 31), a simple suture was performed in 26 patients, while 5 patients needed a mesh repair. Pleural symphysis was performed for all patients who received a thoracic approach. DTE resection was considered complete in 46 patients. Three patients had severe 30-days complications of DTE surgery. Median follow-up was 20 months (range 1-69). Recurrence occurred in 10 patients. CONCLUSION The results emphasize the importance of systematically looking for chest pain in patients suffering from PE and underline the lack of a standardized procedure and treatment in DTE.

Abstract
Endometriosis is a common reproductive disorder in women, with a global prevalence of 10-15%. Long noncoding RNAs (lncRNAs) are critical to gene transcription, cell cycle modulation and immune response. The lncRNA metastasis-associated lung adenocarcinoma transcript 1 (MALAT1) reportedly mediates autophagy of endometrial stromal cells in endometriosis. The present study aimed to evaluate the role and mechanism of MALAT1 in granulosa cells (GCs) in endometriosis. Consequently, MALAT1 expression was upregulated in GCs obtained from patients with endometriosis and in the steroidogenic human granulosa-like tumor cell line KGN. However, MALAT1 knockdown consequently decreased the proliferation and viability of these cells, as determined by MTT and 5-ethynyl-2'-deoxyuridine staining assays. Both Annexin V-fluorescein isothiocyanate/propidium iodide flow cytometry and western blotting performed to detect proapoptotic factors indicated that MALAT1 depletion might promote KGN cell apoptosis. Furthermore, MALAT1 knockdown increased GC autophagy, as evidenced by microtubule-associated protein 1A/1B-light chain 3 (LC3) cleavage upregulation and p62 degradation. In addition, although 5'-AMP-activated protein kinase (AMPK) mRNA expression and protein levels decreased in GCs obtained from patients with endometriosis and KGN cells, MALAT1 knockdown restored AMPK levels. However, addition of BML-275 (MALAT1 inhibitor) to MALAT1-knockdown KGN cells recovered their viability and proliferative capacity and simultaneously reduced their apoptotic and autophagic capacity. Therefore, MALAT1 may regulate GC proliferation via AMPK-mTOR-mediated cell apoptosis and autophagy.

The aim of this review is to reconsider new therapeutic strategies for endometriosis by focusing on estrogen signaling, ROS production and scavenging, and mitochondrial metabolism. Each keyword alone or in combination was used to search from PubMed and Embase by applying the filters of the title and the publication years between January 2000 and May 2020. Abnormal epigenetic marks of estrogen receptors (ERs) in endometriosis cause overexpression of ERβ, progesterone resistance, inflammation, anti-apoptosis, and mitochondrial metabolic modification. In addition to hormonal action, estrogen is involved in various functions such as mitochondrial biosynthesis and energy metabolism. Estrogen works with its downstream target genes to modulate mitochondrial gene expression, regulate ROS production, and affect mitochondrial biology, including ATP production, antioxidant defenses, mitochondrial biosynthesis, quality control, and energy-transducing capacity. Endometriosis can shift mitochondrial metabolism from oxidative phosphorylation to aerobic glycolysis. This metabolic conversion suppresses ROS production and thus activates the survival signal of endometriotic cells. Therefore, molecules associated with aerobic glycolysis and mitochondrial metabolism are considered therapeutic targets for endometriosis. In conclusion, estrogen downstream target genes involved in mitochondrial metabolic biosynthesis may be potential targets for non-hormonal treatment of endometriosis.

Abstract
The purpose of this study was to integrate the existing expression profile data on endometriosis (EM)-related tissues in order to identify the differentially expressed genes. In this study, three series of raw expression data were downloaded from GEO database. Differentially expressed genes (DEGs) in three tissue types were screened. GO, KEGG pathway enrichment analysis, core differential genes (CDGs) protein–protein interaction (PPI) network and weighted gene co-expression network analysis (WGCNA) were performed, finally, the dysregulation of Hippo pathway in ectopic endometrium (EC) was detected by Western blotting. A total of 1,811 DEGs between eutopic (EU) and normal endometrium (NE), 5,947 DEGs between EC and EU, and 3,192 DEGs between EC and NE datasets were identified. After screening, 394 CDGs were obtained, and 5 hub genes identified in the PPI network. CDGs enrichment and WGCNA network analysis revealed cell proliferation, differentiation, migration and other biological processes, Hippo and Wnt signaling pathways, and a variety of tumor-related pathways. Western blotting results showed that YAP/TAZ was upregulated, and MOB1, pMOB1, SAV1, LATS1 and LATS2 were downregulated in EC. Moreover, CDGs, especially the hub genes, are potential biomarkers and therapeutic targets. Finally, the Hippo pathway might play a key role in the development of endometriosis.

Abstract
Aim: To explore the circular RNA (circRNA) profile in cumulus cells from endometriosis-associated infertility patients. Methods: The expression of circRNAs was profiled by high-throughput sequencing. Sanger sequencing was performed to identify the backsplicing site. Six candidate circRNAs and their parental genes were measured in 30 samples by quantitative reverse transcription-polymerase chainreaction (qRT-PCR). Bioinformatics analysis was performed to predict the functions. Results: A total of 55 upregulated and 41 downregulated differentially expressed circRNAs were detected. Kyoto Encyclopedia of Genes and Genomes data indicated that these target genes were mainly involved in cumulus cell growth- and differentiation-related pathways. Hsa_circ_0072391, hsa_circ_0007299 and hsa_circ_0057799 were significantly increased, and hsa_circ_001533 was significantly decreased in endometriosis-associated infertility patients. Conclusion: The differentially expressed circRNAs might be potentially involved in pathophysiology of endometriosis-associated infertility.

Abstract
Endometriosis represents a frequently diagnosed gynecological affliction in the reproductive timespan of women, defined by symptoms ranging from pelvic pain to infertility. A complex interplay between the genetic profile, hormonal activity, menstrual cyclicity, inflammation status, and immunological factors define the phenotypic presentation of endometriosis. To date, imaging techniques represent the gold standard in diagnosing endometriosis, of which transvaginal ultrasonography and magnetic resonance imaging bring the most value to the diagnostic step. Current medical treatment options for endometriosis-associated infertility focus on either stimulating the follicular development and ovulation or on inhibiting the growth and development of endometriotic lesions. Techniques of assisted reproduction consisting of superovulation with in vitro fertilization or intrauterine insemination represent effective treatment alternatives that improve fertility in patients suffering from endometriosis. Emerging therapies such as the usage of antioxidant molecules and stem cells still need future research to prove the therapeutic efficacy in this pathology.

Abstract
Objectives To explore sociodemographic differences and hospital outcomes in endometriosis patients with versus without psychiatric comorbidities. Methods We conducted a cross-sectional study using the Nationwide Inpatient Sample (NIS, 2012-2014), and included 63,160 females with primary diagnosis of endometriosis. We used descriptive statistics and Pearson’s chi-square test to measure the differences in demographics and utilization of gynecologic procedures by the presence of psychiatric comorbidities. Results Psychiatric comorbidities were present in 18.7% inpatients with endometriosis. About three-fourth of these inpatients were in reproductive age group 26-45 years (75.7%) and were whites (79.1%). Psychiatric comorbidities were seen more in females from middle-income families and from the midwest region of the US. There was no significant difference in the utilization of gynecological procedures by the presence of psychiatric comorbidities. However, inpatients with psychiatric comorbidities had a longer mean length of stay (2.5 vs. 2.3 days) and total charges ($35,489 vs. $34,673) compared to the non-psychiatric cohort. Anxiety disorders predominated at 45% in patients with endometriosis followed by depressive disorder (31.3%), psychotic disorders (12.3%), and drug abuse (6.3%). Conclusion Endometriosis with psychiatric comorbidities is prevalent in young white females from a middle-income family. Anxiety and depressive disorders are most prevalent and are associated with extended hospitalization stay and higher charges, thereby negatively impacting the healthcare burden compared to those without psychiatric comorbidities.

Abstract
Endometriosis is a chronic inflammatory hormone-dependent condition associated with pelvic pain and infertility, characterized by the growth of ectopic endometrium outside the uterus. Given its still unknown etiology, treatments usually aim at diminishing pain and/or achieving pregnancy. Despite some progress in defining mode-of-action for drug development, the lack of reliable animal models indicates that novel approaches are required. The difficulties inherent to modeling endometriosis are related to its multifactorial nature, a condition that hinders the recreation of its pathology and the identification of clinically relevant metrics to assess drug efficacy. In this review, we report and comment endometriosis models and how they have led to new therapies. We envision a roadmap for endometriosis research, integrating Artificial Intelligence, three-dimensional cultures and organ-on-chip models as ways to achieve better understanding of physiopathological features and better tailored effective treatments.

Abstract
MicroRNAs (miRNAs), a class of small noncoding RNA molecules, have been recognized as key post-transcriptional regulators associated with a multitude of human diseases. Global expression profiling studies have uncovered hundreds of miRNAs that are dysregulated in several diseases, and yielded many candidate biomarkers. This review will focus on miRNAs in endometriosis, a common chronic disease affecting nearly 10% of reproductive-aged women, which can cause pelvic pain, infertility, and a myriad of other symptoms. Endometriosis has delayed time to diagnosis when compared to other chronic diseases, as there is no current accurate, easily accessible, and noninvasive tool for diagnosis. Specific miRNAs have been identified as potential biomarkers for this disease in multiple studies. These and other miRNAs have been linked to target genes and functional pathways in disease-specific pathophysiology. Highlighting investigations into the roles of tissue and circulating miRNAs in endometriosis, published through June 2018, this review summarizes new connections between miRNA expression and the pathophysiology of endometriosis, including impacts on fertility. Future applications of miRNA biomarkers for precision medicine in diagnosing and managing endometriosis treatment are also discussed.

Down-regulation of long non-coding RNA MALAT1 inhibits granulosa cell proliferation in endometriosis by up-regulating P21 via activation of the ERK/MAPK pathway. Mol Hum Reprod 2020; 25:17-29. [PMID: 30371869 DOI: 10.1093/molehr/gay045] [Citation(s) in RCA: 49] [Impact Index Per Article: 12.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/17/2018] [Accepted: 10/25/2018] [Indexed: 12/17/2022] Open
Abstract
STUDY QUESTION Is there a specific mechanism underlying the association between lung adenocarcinoma transcript 1 (MALAT1) and endometriosis-related infertility? SUMMARY ANSWER The down-regulation of MALAT1 in endometriosis granulosa cells (GCs) may have an adverse effect on the growth and development of oocytes by inhibiting GC proliferation, due to cell cycle-dependent mechanisms that enhance P21 expression through activation of the extracellular signal-regulated kinase (ERK)/mitogen-activated protein kinase (MAPK) pathway. WHAT IS KNOWN ALREADY The association between endometriosis and infertility is well supported throughout the literature, and endometriosis per se and its surgical treatment have an adverse effect on the ovarian reserve and on oocyte development. MALAT1, one of the most extensively expressed and evolutionarily conserved transcripts, has been implicated to play a role in human development and many diseases. However, little is known about the role of MALAT1 long non-coding RNA (lncRNA) in endometriosis and its associated infertility. STUDY DESIGN, SIZE, DURATION We measured MALAT1 lncRNA expression levels in GCs from 52 endometriosis patients and 52 controls. Also, MALAT1 was knocked down in a human GC tumor-derived cell line, KGN, to investigate the role of MALAT1 and its molecular mechanism in cell proliferation. PARTICIPANTS/MATERIALS, SETTING, METHODS GCs were collected from women with or without endometriosis undergoing IVF or ICSI treatment. All endometriosis patients were diagnosed by laparoscopy or laparotomy, and control patients were limited to male factor or tubal disease and had a normal ovarian reserve. Quantitative real-time PCR (qRT-PCR) was used to measure the differential expression levels of MALAT1 lncRNA between endometriosis patients and controls. The receiver operating characteristic (ROC) curve was drawn to evaluate the diagnostic values of MALAT1 in endometriosis. In the KGN cell line, MALAT1 was knocked down with locked nucleic acid GapmeRs. Cell counting kit-8 assays, ethynyl-2-deoxyuridine assays and flow cytometry were used to study the role of MALAT1 in cell proliferation and cell-cycle progression, and western blotting was performed to detect the potential underlying mechanism. MAIN RESULTS AND THE ROLE OF CHANCE We first found that MALAT1 lncRNA was significantly down-regulated in endometriosis GCs and was associated with the antral follicle count (R = 0.376, P < 0.001 versus control). In addition, MALAT1 lncRNA levels were significantly lower in the GCs of infertile women with advanced stages of endometriosis (P = 0.01 versus control). The ROC curves illustrated strong separation between all the endometriosis patients and the control group (AUC: 0.705; 95% CI: 0.606-0.804; P < 0.001), Stage I-II and control group (AUC: 0.651; 95% CI: 0.536-0.767; P = 0.016), and Stage III-IV and control group (AUC: 0.827; 95% CI: 0.718-0.936; P < 0.001). MALAT1 lncRNA was primarily localized in the nuclei of GCs. We found a negative correlation between MALAT1 lncRNA and P21 mRNA in the GCs from patients (R = -0.628; P < 0.001). MALAT1 knockdown in KGN cells inhibited cell proliferation and cell-cycle progression. In addition, MALAT1 knockdown induced an increase in both the mRNA and protein levels of P21, and of P53, phosphorylated ERK1/2 (p-ERK1/2) and phosphorylated c-Jun N-terminal protein kinase (p-JNK) protein levels, as well as causing a decrease in cyclin dependent kinase 2 (CDK2), cyclin D1 and p-P38 MAPK protein levels. Furthermore, inhibition of the ERK/MAPK pathway with U0126, the up-regulation of p-ERK1/2, P21 and P53, and the down-regulation of CDK2 and cyclin D1 by the knockdown of MALAT1 were all attenuated by MALAT1 knockdown. Therefore, MALAT1 may regulate GC proliferation through P21/P53-dependent control of the cell cycle, and the ERK/MAPK pathway participates in this process. LARGE SCALE DATA None. LIMITATIONS, REASONS FOR CAUTION The hormonal treatment used in IVF and surgical removal of endometriotic lesions may have altered MALAT1 expression in GCs. The ovarian granulosa-like tumor cell line, KGN, was used for further functional and mechanistic studies due to the difficulties in obtaining human GCs in sizable amounts and maintaining primary cultures. WIDER IMPLICATIONS OF THE FINDINGS Our finding represents the first example of an lncRNA-based mechanism in endometriosis GCs. Women with endometriosis show altered MALAT1 expression levels in GCs that may impair fertility by regulating the function of GCs. Therefore, analysis of MALAT1 and its molecular mechanisms of action provide new insights into the pathogenesis of endometriosis and its associated infertility.

Abstract
Endometriosis is a frequent and chronic inflammatory disease with impacts on reproduction, health and quality of life. This disorder is highly estrogen-dependent and the purpose of hormonal treatments is to decrease the endogenous ovarian production of estrogens. High estrogen production is a consistently observed endocrine feature of endometriosis. mRNA and protein levels of estrogen receptors (ER) are different between a normal healthy endometrium and ectopic/eutopic endometrial lesions: endometriotic stromal cells express extraordinarily higher ERβ and significantly lower ERα levels compared with endometrial stromal cells. Aberrant epigenetic regulation such as DNA methylation in endometriotic cells is associated with the pathogenesis and development of endometriosis. Although there is a large body of data regarding ERs in endometriosis, our understanding of the roles of ERα and ERβ in the pathogenesis of endometriosis remains incomplete. The goal of this review is to provide an overview of the links between endometriosis, ERs and the recent advances of treatment strategies based on ERs modulation. We will also attempt to summarize the current understanding of the molecular and cellular mechanisms of action of ERs and how this could pave the way to new therapeutic strategies.

Abstract
INTRODUCTION Deep dyspareunia, a common symptom in endometriosis, has previously been associated with bladder and/or pelvic floor tenderness (BPFT), which suggests a role for central nervous system sensitization. The Central Sensitization Inventory (CSI, 0-100) is a validated self-reported scale for patients with central sensitization. AIM The objective of this study was to phenotype deep dyspareunia using BPFT and the CSI. METHODS The methods included cross-sectional analysis from a prospective registry from January 2018 to June 2018 at a tertiary center for endometriosis (ClinicalTrials.gov #NCT02911090). Included were women aged 18-50 years with endometriosis (previously surgically diagnosed, current visualized endometrioma on ultrasound, or current palpable or visualized nodule on ultrasound), who were newly or re-referred to the center. Severity of deep dyspareunia was self-reported using an 11-point numeric rating scale (0 = no pain; 10 = worst pain imaginable), categorized as no or low deep dyspareunia (0-4) and high deep dyspareunia (5-10). We identified the subgroup with high deep dyspareunia and presence of BPFT, where we hypothesized a central component of the sexual pain. This subgroup was compared with 2 other subgroups: no or low deep dyspareunia and high deep dyspareunia but no BPFT. The CSI was compared between the groups using analysis of variance, followed by post hoc testing (P < .05). MAIN OUTCOME MEASURE The main outcome measure was the CSI score ranging from 0 to 100. RESULTS Data from 163 women with endometriosis were analyzed. The mean age of this cohort was 36.4 ± 6.8 years, and the mean CSI score was 41.0 ± 18.6. 37 percent (61/163) had high deep dyspareunia and BPFT; 29% (47/163) had high deep dyspareunia and no BPFT; and 34% (55/163) had no or low deep dyspareunia. The CSI significantly differed between the 3 groups (analysis of variance: F = 22.4, P < .001). In post hoc testing, the CSI was higher in women with high deep dyspareunia and BPFT (51.3 ± 16.9), compared with women with no or low deep dyspareunia (30.9 ± 15.4, P < .001) and compared with women with high deep dyspareunia but no BPFT (39.4 ± 17.2, P = .001). CLINICAL IMPLICATIONS The CSI could be used to classify and phenotype patients with endometriosis-associated sexual pain. STRENGTH & LIMITATIONS Strengths include a prospective registry with integrated pain scores, validated questionnaires, and physical examination findings. Limitations include the lack of quantitative sensory testing for central sensitization. CONCLUSIONS In women with endometriosis, the subgroup with high deep dyspareunia and bladder and/or pelvic floor tenderness had a significantly higher score on the CSI than other subgroups, suggesting that this group may have a central component to their sexual pain.

Platelets induce increased estrogen production through NF-κB and TGF-β1 signaling pathways in endometriotic stromal cells. Sci Rep 2020; 10:1281. [PMID: 31992765 PMCID: PMC6987096 DOI: 10.1038/s41598-020-57997-6] [Citation(s) in RCA: 15] [Impact Index Per Article: 3.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/12/2019] [Accepted: 08/07/2019] [Indexed: 12/11/2022] Open
Abstract
Endometriosis is estrogen-dependent disorder. Two theories provide the explanations for the increased estrogen production. One is the feed-forward loop model linking inflammation and estrogen production. The more recent model evokes the tissue hypoxia resulting from endometrial debris detached and then regurgitated to the peritoneal cavity. Both models tacitly assume that everything occurs within the endometriotic stromal cells, seemingly without the need for exogenous factors. This study was undertaken to investigate as whether platelets may be responsible for local estrogen overproduction. We employed in vitro experimentation that evaluated the 17β-estradiol (E2) levels in endometriotic stromal cells treated with activated platelets, and the genes and protein expression levels of StAR, HSD3B2, aromatase, and HSD17B1, as well as their upstream genes/proteins such as NF-κB, TGF-β1, HIF-1α, SF-1 and phosphorylated CREB. In addition, we conducted 2 animal experimentations using platelet depletion/infusion and also neutralization of NF-κB and TGF-β1, followed by immunohistochemistry analysis of involved in StAR, HSD3B2, aromatase, and HSD17B1, as well as SF-1 and p-CREB. We found that treatment of endometriotic stromal cells by activated platelets increase the E2 production by 4.5 fold, and concomitant with increased gene and protein expression of StAR, HSD3B2, aromatase, and HSD17B1, the four genes/enzymes important to estrogen synthesis, along with their upstream genes HIF-1α, SF-1 and phosphorylated CREB. Moreover, platelets activate these genes through the activation of NF-κB and/or TGF-β1, and antagonism of either signaling pathway can abolish the induction of the 4 genes and thus increased estrogen production. The two animal experimentations confirmed these changes. Thus, platelets increase the E2 production in endometriotic stromal cells through upregulation of StAR, HSD3B2, aromatase, and HSD17B1 via the activation of NF-κB and/or TGF-β1. These findings provide a yet another compelling piece of evidence that endometriotic lesions are indeed wounds undergoing repeated tissue injury and repair. They strongly indicate that non-hormonal therapeutics for endometriosis is theoretically viable, with anti-platelet therapy being one promising avenue.

Abstract
INTRODUCTION The etiology of endometriosis-associated deep dyspareunia may include direct endometriosis-specific factors (eg, stage or invasiveness of disease) and/or indirect contributors such as bladder/pelvic floor dysfunction (eg, related to myofascial mechanisms or nervous system sensitization). AIM This study aimed to determine whether bladder/pelvic floor tenderness and painful bladder syndrome were associated with severity of deep dyspareunia in women with endometriosis, regardless of Stage (I/II vs III/IV) or other endometriosis-specific factors. METHODS Observational study from a prospective patient registry (January 2014 to December 2016) at a tertiary centre for endometriosis. Included were women aged 18 to 49 years who had surgical removal and histopathologic confirmation of endometriosis at the centre. Cases with Stage I/II vs Stage III/IV endometriosis were analyzed separately. Bivariate associations with the primary outcome (severity of deep dyspareunia) were tested for bladder/pelvic floor tenderness, painful bladder syndrome, as well as endometriosis-specific factors identified at the time of laparoscopic surgery (eg, deep infiltrating endometriosis) and demographic factors (eg, age). Multivariable ordinal logistic regression was carried out to adjust for factors associated with the primary outcome. MAIN OUTCOME MEASURE Primary outcome was severity of deep dyspareunia on an 11-point numeric rating scale, categorized as none/mild (0-3), moderate (4-6), and severe (7-10), from a preoperative self-reported questionnaire. RESULTS Overall, 411 women had surgically confirmed endometriosis: 263 had Stage I/II and 148 had Stage III/IV endometriosis. Among women with Stage I/II endometriosis, severity of deep dyspareunia was associated with both bladder/pelvic floor tenderness and painful bladder syndrome (AOR = 1.94, 95% CI: 1.11-3.38, P = .019 and AOR = 1.99, 95% CI: 1.15-3.44, P = .013, respectively), independent of endometriosis-specific factors or other factors associated with deep dyspareunia severity. Similar associations were found in women with Stage III/IV endometriosis (bladder/pelvic floor tenderness AOR =2.51, 95% CI: 1.25-5.02, P = .01, painful bladder syndrome: AOR = 1.90, 95% CI: 1.01-3.57, P = .048). CLINICAL IMPLICATIONS Myofascial or nervous system mechanisms may be important for deep dyspareunia in women with endometriosis, even in those with moderate-to-severe disease (Stage III/IV). STRENGTHS & LIMITATIONS Strengths include the prospective registry, and histological confirmation of endometriosis and staging by experienced endometriosis surgeons. Limitations include assessment of only one pelvic floor muscle (levator ani). CONCLUSION In women with Stage I/II or Stage III/IV endometriosis, severity of deep dyspareunia was strongly associated with bladder/pelvic floor tenderness and painful bladder syndrome, independent of endometriosis-specific factors, which suggests the role of myofascial or sensitization pain mechanisms in some women with deep dyspareunia.

Abstract
Pelvic endometriosis is a complex syndrome characterized by an estrogen-dependent chronic inflammatory process that affects primarily pelvic tissues, including the ovaries. It is caused when shed endometrial tissue travels retrograde into the lower abdominal cavity. Endometriosis is the most common cause of chronic pelvic pain in women and is associated with infertility. The underlying pathologic mechanisms in the intracavitary endometrium and extrauterine endometriotic tissue involve defectively programmed endometrial mesenchymal progenitor/stem cells. Although endometriotic stromal cells, which compose the bulk of endometriotic lesions, do not carry somatic mutations, they demonstrate specific epigenetic abnormalities that alter expression of key transcription factors. For example, GATA-binding factor-6 overexpression transforms an endometrial stromal cell to an endometriotic phenotype, and steroidogenic factor-1 overexpression causes excessive production of estrogen, which drives inflammation via pathologically high levels of estrogen receptor-β. Progesterone receptor deficiency causes progesterone resistance. Populations of endometrial and endometriotic epithelial cells also harbor multiple cancer driver mutations, such as KRAS, which may be associated with the establishment of pelvic endometriosis or ovarian cancer. It is not known how interactions between epigenomically defective stromal cells and the mutated genes in epithelial cells contribute to the pathogenesis of endometriosis. Endometriosis-associated pelvic pain is managed by suppression of ovulatory menses and estrogen production, cyclooxygenase inhibitors, and surgical removal of pelvic lesions, and in vitro fertilization is frequently used to overcome infertility. Although novel targeted treatments are becoming available, as endometriosis pathophysiology is better understood, preventive approaches such as long-term ovulation suppression may play a critical role in the future.

Abstract
INTRODUCTION Magnetic resonance (MR) relaxometry provides a noninvasive predictive tool to discriminate between benign ovarian endometrioma (OE) and endometriosis-associated ovarian cancer (EAOC). Transverse relaxation rate R2 value was determined using a single-voxel, multi-echo MR sequence (HISTO) by a 3T-MR system. R2 with cutoff value of 12.1 s was established to discriminate between benign and malignant tumors. PATIENT CONCERNS We present a case of a 39-year-old woman who was initially thought to be malignant transformation of endometriosis by diagnostic MR imaging of the vascularized solid components. DIAGNOSIS A R2 value of 42.62 s on MR relaxometry demonstrated that this case is non-malignant. INTERVENTIONS To confirm the diagnose, left salpingo-oophorectomy by laparoscopic surgery was performed. OUTCOMES Histopathological results revealed seromucinous borderline tumor (SMBT). Our experience suggests that preoperative MR relaxometry may be useful for discriminating "borderline (SMBT)" from "malignancy (EAOC)." Furthermore, immunohistochemical studies of this case demonstrated ovarian SMBT cells were positive for estrogen receptor, progesterone receptor, and hepatocyte nuclear factor-1beta. A similar expression pattern was also observed in patients with benign OE. LESSONS In many respects, SMBT characteristics differ from those of EAOC but resemble those of benign OE. MR relaxometry unveils a new clinical approach as an adjunctive modality for discriminating SMBT from EAOC.

Abstract
Background Abdominal wall endometriomas are quite uncommon. They are usually misdiagnosed by both the surgeon and the gynaecologist. Awareness of the details of this rare condition is therefore essential for prompt diagnosis and adequate treatment. Introduction Endometriosis though a condition commonly seen in the pelvic region can also occur at extrapelvic sites giving rise to a diagnostic dilemma. Abdominal wall endometrioma is one such complex variant of extrapelvic endometriosis with an incidence of less than 2% following gynaecologic operations. Case Report A case of abdominal wall endometrioma diagnosed clinically and treated by wide surgical resection is presented to highlight the importance of clinical evaluation in the diagnosis of this condition. Discussion The etiopathogenesis, presentation, investigations, and management are discussed briefly. Conclusion Clinical evaluation confirmed by supportive imaging is diagnostic. Wide local excision is the mainstay of treatment.

Abstract
Endometriosis is an estrogen-dependent chronic disease defined by the presence of endometrial-like tissue, glands and stroma in ectopic areas. Among all the pathogenic theories proposed to explain the origin of the disease, a pivotal role for immune, hormonal, and epigenetic disbalances have been hypothesized. Endometriosis affects up to 10%–15% of women in reproductive age and represents one of the most common gynecological causes of severe pelvic pain. The main symptoms reported by patients are dysmenorrhea and deep dyspareunia. Although the histological confirmation has been commonly considered mandatory, to date the possibility offered by the improvement in imagining techniques allows to make a proper diagnosis of the disease in most of the cases. Medical therapy represents only a symptomatic treatment and not the definitive solution. The aim of the hormonal therapy is to abolish the menstrual flow using progestin, oral contraceptives, and gonadotropin-releasing hormone agonists to reduce pelvic pain. Surgical treatment consisting of laparoscopy has the goal of abolishing pain and may be conservative or radical in nature depending on the patients’ desire of spontaneous conception in the future. Radical surgery seems to be associated with a higher percentage of pain relief as well as higher recurrence rates. Due to the worldwide acceptance and the ongoing evolution of minimally invasive surgery to treat both benign and malignant diseases, future investigations may be conducted to consider this approach to save the function of all the organs involved by the disease and to reduce post-operative discomfort and psychological impact.

Abstract
Endometriosis is a gynecologic disease common among reproductive-aged women caused by the growth of endometrial tissue outside the uterus. Altered expression of numerous genes and microRNAs has been reported in endometriosis. Steroidogenic factor 1 (SF-1), an essential transcriptional regulator of multiple genes involved in estrogen biosynthesis, is aberrantly increased and plays an important role in the pathogenesis of endometriosis. Here, we show the expression of SF-1 in endometriosis is regulated by miR-370-3p. Sera and tissue were collected from 20 women surgically diagnosed with endometriosis and 26 women without endometriosis. We found that miR-370-3p levels were decreased in the serum of patients with endometriosis while SF-1 mRNA levels were inversely upregulated in endometriotic lesions compared with respective controls. Transfection of primary endometriotic cells with miR-370-3p mimic or inhibitor resulted in the altered expression of SF-1 and SF-1 downstream target genes steroidogenic acute regulatory protein (StAR) and CYP19A1. Overexpression of miR-370-3p inhibited cell proliferation and induced apoptosis in endometriotic cells. This study reveals that miR-370-3p functions as a negative regulator of SF-1 and cell proliferation in endometriotic cells. We suggest a novel therapeutic strategy for controlling SF-1 in endometriosis.

Abstract
Noscapine is a natural alkaloid with anti-angiogenesis activities. The aim of the present study was to examine the effect of noscapine on eutopic endometrium of endometriosis patients (EEE) and normal endometrium (NE) in a three-dimensional (3D) culture model. In this experimental in-vitro study, EEE (n = 8) and NE (n = 8) biopsies were taken from 16 reproductive aged women. The biopsies were cleared from blood and mucus. Each biopsy was cut into small fragments (1 × 1 mm) in a sterile condition. For 3D culture, the endometrial fragments were put between two layers of fibrin jell made of fibrinogen solution [3 mg/mL in Medium199 (M199) + thrombin]. Twenty-four wells of culture dish was divided into 5 groups for each biopsy: the control wells were treated with M199 containing 5% fetal bovine serum (FBS) while, the test wells were exposed to the same media containing one of the noscapine doses (10, 50, 100, and 200 μM). The expression of apoptotic genes, growth score, angiogenesis, and nitric oxide (NO) secretion were evaluated. The mean of growth score of groups exposed to 0, 10, 50, 100, and 200 μM were 2.2 ± 0.55, 1.7 ± 0.45, 1.44 ± 0.27, 0.29 ± 0.1, and 0.1 ± 0.08 in EEE, and also, 2.11 ± 0.6, 1.65 ± 0.5, 0.79 ± 0.41, 0.18 ± 0.1, and 0.1 ± 0.1 in NE, respectively, and the difference between the groups was significant (P < 0.05). The expression of apoptotic genes significantly increased while, the levels of Bcl-2 and Sirt1 reduced (P = 0.004). NO secretion reduced significantly (P < 0.05) in both EEE and NE groups. In conclusion, higher doses of noscapine showed inhibitory effect on growth and angiogenesis of EEE and NE.
