Kirmizi DA, Baser E, Okan A, Doganyigit Z. Receptivity, autophagy, and implantation in endometriosis; does antioxidant work? An experimental study. J Food Biochem 2022; 46:e14276. [PMID: 35712902 DOI: 10.1111/jfbc.14276] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/01/2022] [Revised: 04/24/2022] [Accepted: 05/30/2022] [Indexed: 11/30/2022]
Abstract
Implantation is a key point in pathological processes associated with infertility, especially in endometriosis. In this complex process, there is limited evidence to demonstrate the role of receptivity and autophagy. The present study aimed to evaluate LC3A/B, P62/SQSTM1, Beclin 1, and integrin expressions and receptivity and autophagy processes in endometriosis in pregnant rats with healthy endometriosis on day 6 of the process. Pregnancy was observed in all rats in the control group (8/8), while the pregnancy was 4/8 in the endometriosis group, and 6/8 in the endometriosis + ALA group. LC3A/B and P62/SQSTM1 expression increased significantly in the endometriosis + ALA group, compared with endometriosis groups (p < .05). The effect of ALA on autophagy and receptivity in endometriosis was shown for the first time. Antioxidant and anti-inflammatory treatments in endometriosis should be investigated as new treatment modalities for implantation problems. PRACTICAL APPLICATIONS: Endometriosis, the etiology of which remains unknown, is an important cause of infertility. Implantation is the key point in pathological processes associated with infertility. In this complex process, there is limited evidence to demonstrate the role of receptivity and autophagy. The present study aimed to evaluate LC3A/B, P62/SQSTM1, Beclin 1, and integrin expressions and receptivity and autophagy processes in endometriosis in pregnant rats with healthy endometriosis on day 6 of the process. Oral alpha-lipoic acid was administered to one group and the effect of this powerful antioxidant on the process was evaluated.

The RNA-seq based endometrial receptivity test (rsERT) compared to pinopode: A better diagnostic tool for endometrial receptivity for patients with recurrent implantation failure in Chinese population. Front Endocrinol (Lausanne) 2022; 13:1009161. [PMID: 36339409 PMCID: PMC9634259 DOI: 10.3389/fendo.2022.1009161] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/01/2022] [Accepted: 10/06/2022] [Indexed: 11/24/2022] Open
Abstract
Displaced window of implantation (WOI) is one of the endometrial origins that accounts for implantation failure, especially for patients with recurrent implantation failure (RIF), yet no standard diagnostic tool has been recognized. The study consists of two parts, aiming to compare the concordance and efficacy of the diagnostic tools, the newly developed RNA-seq based endometrial receptivity test (rsERT) to the conventional pinopode, in diagnosing WOI and guiding personalized embryo transfer (pET). With the same group of RIF patients, the rsERT diagnosed 32 patients (65.31%) with normal WOIs, and most of the displacements were advancements (30.61%). While according to pinopode, only 14 patients (28.57%) were found with normal WOIs, and most patients (63.27%) presented delayed growth patterns. After conducting pET, patients in the rsERT group had higher successful pregnancy rates while requiring fewer ET cycles (50.00% vs. 16.67%, p=0.001). The study proved poor consistency between the diagnostic tools of endometrial receptivity based on cellular structure and gene profiling, and it supported rsERT as a reliable tool with potential clinical value.

Abstract
BACKGROUND
Despite numerous studies and a not decreasing amount of endometriosis and associated infertility, the study of endometriosis- associated infertility does not lose its relevance, and the characteristics of the endometrium is appeared to be central and predictive factors that determine the success of overcoming infertility.
OBJECTIVE
To reflect the molecular genetic features of the state of the endometrium with endometriosis associated with infertility, expand the understanding of its pathogenesis, substantiate theoretical aspects of the use of hormonal preimplantation preparation of the endometrium in endometriosis-associated infertility.
MATERIALS AND METHODS
To write this review, we searched for domestic and foreign publications in Russian and international search systems (eLIBRARY, PubMed, MedLine, Crossref, etc.) over the past 1–16 years.
RESULTS
The model of changes in endometrial receptivity is examined the mechanisms of resistance to progesterone and overproduction of estrogens as key endometrial factors in the pathogenesis of endometriosis-associated infertility and theoretical justification for the use of hormonal therapy for the preimplantation preparation of compromised endometrium is given.
CONCLUSION
Despite the large number of publications, there is no consensus and the same approaches to determining the receptivity of the endometrium and its role in implantation disorders in endometriosis, as well as clear ideas about the pathogenesis of endometriosis-associated infertility. A personalized approach in the management of patients with endometriosis-associated infertility will lead to a common denominator of many factors affecting reproduction and determine their potential role in both the diagnosis and treatment of a particular patient.

Abstract
OBJECTIVE to identify novel biomarkers for peritoneal endometriosis in eutopic endometrium thus giving an oportunity for non-invasive diagnosis. DESIGN A cross-sectional single-center study SETTING: tertiary care hospital PATIENTS: 49 patients subjected to laparoscopy because of suspected endometriosis, 33 patients out of the group qualified to the study had sufficient endometrial tissue taken and were in their follicular phase of menstrual cycle. INTERVENTIONS biopsy sampling of eutopic endometrial tissue during diagnostic or diagnostic and terapeutic laparoscopy, questionaires, MAIN OUTCOME MEASURE(S): qRT-PCR to evaluate the mRNA expression of selected candidate marker genes in endometrium: ARO1 (aromatase), CXCL8 (interleukin 8), NGF (nerve growth factor), VEGF-A (vascular endothelial growth factor A), PDGF-A (platelet-derived growth factor A). RESULTS mRNA expression of ARO1, CXCL8, VEGF-A and PDGF-A did not differ significantly between women with and without endometriosis. NGF mRNA expression was decreased in women with endometriosis. CONCLUSIONS Observed preliminary results suggest a possible role of NGF in early diagnosis of peritoneal endometriosis. The role of NGF changes in eutopic endometrium of patients with peritoneal endometriosis needs further evaluation.

Expression of Pinopodes in the Endometrium from Recurrent Pregnancy Loss Women. Role of Thrombomodulin and Ezrin. J Clin Med 2020; 9:E2634.

Abstract
BACKGROUND Pinopode expression has been suggested as a marker of endometrial receptivity. METHODS We set up an experimental study comparing endometrial tissue from recurrent pregnancy loss (RPL, n = 30) and fertile control (CTR, n = 20) women in terms of pinopode expression/morphology; expression of thrombomodulin (TM) and ezrin; cytoskeletal organization. Endometrial samples were collected during implantation window and evaluated by scanning electron microscopy, western blot, and immunofluorescence. RESULTS We found that RPL endometrial tissue showed: (i) increased pinopodes density (* p < 0.05); (ii) a reduced diameter of pinopodes (* p < 0.05); (iii) a decreased TM and ezrin expression (p < 0.05). Additionally, confocal images showed a significantly reduced expression of phosphorylated (p)-ezrin, confirming the results obtained through immunoblot analysis. Immunofluorescence staining showed that in CTR samples, junctions between cells are intact and clearly visible, whereas actin filaments appear completely lost in RPL endometrial samples; this suggests that, due to the impaired expression and activity of TM and ezrin, actin does not bind to plasma membrane in order to orchestrate the cytoskeletal actin filaments. CONCLUSIONS Our findings suggest that an impaired expression of TM and expression/activation of ezrin may affect the connection between the TM and actin cytoskeleton, impairing the organization of cytoskeleton and, eventually, the adequate pinopode development.

Abstract
RESEARCH QUESTION Do endometrial stromal cells from primary infertile patients with severe ovarian endometriosis display differential secretory profiles of inflammation-associated cytokines during the implantation window that may cause infertility? DESIGN Forty-eight cytokines were measured in conditioned medium of isolated endometrial stromal cells obtained from primary infertile patients without endometriosis (control group, n = 12) or with stage IV ovarian endometriosis (ovarian endometriosis group, n = 14) using multiplex assays. Key cytokines showing differential secretory profiles were validated using Western immunoblotting. Cellular phenotypic validation was carried out in vitro by comparing proliferation and migration capacity between control (n = 6) and ovarian endometriosis (n = 7) groups. RESULTS CCL3, CCL4, CCL5, CXCL10, FGF2, IFNG, IL1RN, IL5, TNFA, and VEGF could be detected only in the conditioned media of stromal cells obtained from the ovarian endometriosis group. Among other cytokines detected in the conditioned media of both groups, CCL2 (P = 0.0018), CSF3 (P = 0.0017), IL1B (P = 0.0066), IL4 (P = 0.036), IL6 (P = 0.0039) and IL13 (P = 0.036) were found to be higher, whereas the concentration of IL18 was lower (P = 0.023) in the ovarian endometriosis group. Concentrations of CCL2, IL1B, IL4 and IL13 in conditioned medium reflected significant diagnostic performance for predicting ovarian endometriosis. Cellular phenotypic validation in vitro revealed an enhanced proliferative phenotype (P = 0.046) with no change in cell migratory capacity of endometrial stromal cells from the ovarian endometriosis group. CONCLUSIONS Endometrial stromal cells derived from severe ovarian endometriosis samples displayed a hyperinflammatory and hyperproliferative bias in the endometrial stroma during the 'window of implantation' putatively causing loss of fecundability.

Abstract
Successful embryo implantation is a complex and highly regulated process involving precise synchronization between the fetal-derived trophoblast cells and maternal uterine luminal epithelium. Multiple endocrine-driven factors are important for controlling the timely receptivity of the uterus, and this complexity underscores implantation failure as a major cause of recurrent infertility associated with assisted reproductive technologies. One particular cellular structure often hypothesized to promote receptivity is the pinopode or uterodome - a hormonally regulated, large cellular protrusion on the uterine epithelial surface. Recent clinical studies associate pinopodes with favorable fertility outcomes in women, and because they are directly linked to an increase in progesterone levels, the potential utility of these hormone-regulated cell biological structures in predicting or improving implantation in a clinical setting holds promise. In this review, we aim to generate interest in pinopodes from the broader cell biology and endocrinology communities, re-examine methodologies in pinopode research, and identify priorities for future investigation of pinopode structure and function in women's reproductive health.

Abstract
Endometriosis is a highly prevalent disease among women of reproductive age and
is frequently associated to infertility. However, the mechanisms underlying
endometriosis-related infertility are still not completely known. Several
studies have been conducted in order to elucidate this question. Besides
anatomical changes that may impair gametes and embryo transport along the tubes;
a smaller ovarian reserve due to advanced endometriosis and endometriomas; and a
dysregulated hypothalamic-pituitary-ovarian axis, there are pieces of evidence
suggesting that the peritoneal ectopic endometrial foci may induce a local
inflammatory response, with the recruitment of macrophages, cytokine release,
and reactive oxygen species generation, leading to a pro-oxidant peritoneal
microenvironment. These alterations may be systemically reflected and also
affect the follicular microenvironment. A harmful follicular fluid may disrupt
cumulus cells functions and, consequently, compromise oocyte competence. There
is also evidence suggesting that the peritoneal fluid of women with
endometriosis may alter sperm function. Reduced endometrial receptivity is also
pointed as a possible mechanism involved in endometriosis-related infertility,
which needs further investigation.

Abstract
Endometriosis is currently considered as one of the most common diseases associated with infertility. A controversial issue is whether endometriosis per se exerts a detrimental effect on IVF outcomes. Failure of implantation due to endometriosis-associated infertility is a contradictory and widely discussed burden nowadays. The purpose of the study is to assess the quality of embryos and implantation rate in women with infertility associated with endometriosis. The study included infertile reproductive aged women, between 26 and 40 years who underwent IVF and ICSI procedures. The patients were divided into two groups: group I (n = 70) involved 70 patients with recurrent unilateral endometriomas, II control group (n = 50) with tubal factor infertility. The quality of the retrieved embryos was assessed according to the generally accepted classification of Gardner, indicating the rate of implantation in each group. Embryo transfer was performed in case of high quality embryos. Assessing the ovarian reserve indicators, in the group I patients with recurrent unilateral endometriomas the serum level of AMH was significantly lower (2.1 ± 1.75 vs. 3.2 ± 1.4, p < .005), as well as the number of retrieved oocytes (8.1 ± 3.9 and 10.1 ± 6.8, p < .005). The analysis of the results demonstrated that the duration of stimulation in the group patients with recurrent unilateral endometriomas was significantly higher in comparison with the group II (12.2 ± 1.8 and 10.2 ± 1.6 days, p < .001). Nevertheless, the number of good quality embryos retrieved was comparable in both groups (2.2 ± 1.5 and 2.8 ± 1.8). In the group I patients with recurrent unilateral endometriomas, there was a statistically significant decrease of implantation rate (17.1% vs. 24% p < .005). The results of the study revealed no statistical difference in embryo quality in the study cohort. However, it is important to note that a statistically significant difference in implantation rate in the group of endometriosis-associated infertility compared was obtained 1.5 times lower than in the control group (15.8% vs. 24.0% p < .005). The achieved results demonstrated an adverse IVF outcome in infertile women with recurrent endometrioma compared to the control group.

Abstract
Ultrastructural changes on the apical surface of the luminal epithelium of the uterus are known as pinopodes. Their morphology in species and in special species is associated with different results about size, duration, and percentage of surface area covered by pinopodes. The content of pinopodes is different in rodents and humans. In mice and rats pinopodes have many vacuoles and no organelle that extends to the actin stalk above the microvilli. Human pinopodes do not have a large vacuole and contain the golgi complex, a rough endoplasmic reticulum, secretory vesicles, and mitochondria that extend from the entire cell surface. It has been suggested that pinopodes are good markers of endometrial receptivity and implantation window. There are several molecular markers related to the presence of pinopodes, including integrins, leukemia inhibiting factor (LIF), l-selectin, HOXA10, glutaredoxin, glycodelinA, heparin-binding epidermal growth factor, mucins, and microRNAs (miRNAs). Multiple lines of evidence have indicated that miRNAs could affect the expression of LIF and pinopodes in the endometrium and these molecules play key roles in implantation window processes. Here, we have summarized the morphology and function of pinopodes. Moreover, we have highlighted several molecules in relation to pinopodes that could be used as biomarkers.
