[PMID: 38092313 DOI: 10.1016/j.xfss.2023.12.004] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/12/2023] [Revised: 12/05/2023] [Accepted: 12/06/2023] [Indexed: 01/03/2024]
Abstract
OBJECTIVE To identify cytokines or extracellular matrix components that contribute to adhesion to, and invasion of, the peritoneum, proximal to lesions in the early phase of endometriosis. DESIGN Laboratory-based study. SETTING University Hospital and Laboratory of Animal Science. PATIENTS AND ANIMALS Five women with ovarian endometrioma, 138 wild-type (WT) C57BL/6N mice, and 48 Tenascin C (Tnc) knockout (TncKO) mice. INTERVENTIONS To establish a murine endometriosis model, 20 pieces of minced uterine tissue fragments from each horn were administered intraperitoneally to syngeneic mice. Three days later, endometriotic lesions and peritoneal tissues were collected. Separately, we transfected human peritoneal mesothelial cells (HMrSV5) or human endometrial stromal cells (hESCs) with Tnc small interfering ribonucleic acid. MAIN OUTCOME MEASURES We employed a polymerase chain reaction array to profile gene expression in the murine peritoneum, in both peritoneum distal to lesions and peritoneum surrounding lesions (PSL). The expression of upregulated genes in the PSL was verified in the peritoneal samples by real-time reverse transcription-polymerase chain reaction. TncKO mice were used to investigate the role of Tnc in the development of endometriosis. We evaluated the proliferative activity or inflammatory state of lesions by Ki67 or CD3 immunostaining. Intraperitoneal distribution of macrophages was assessed by fluorescence-activated cell sorting. Using Tnc small interfering ribonucleic acid, we examined the invasive capacity of hESCs in a coculture system with HMrSV5. RESULTS Tnc gene expression was significantly higher in PSL than in peritoneum distal to lesions. The weight and number of TncKO lesions in TncKO hosts were lower than those of WT lesions in WT hosts. In contrast, the weight and number of nonattached TncKO lesions in TncKO hosts were higher than those of nonattached WT lesions in WT hosts. We observed decreased Ki67-positive cells or H-scores for CD3, a lower proportion of M1 macrophages, and a higher proportion of M2 macrophages in TncKO lesions in TncKO recipients. Silencing of Tnc expression in hESCs and HMrSV5 diminished the invasivity of hESCs. CONCLUSION Tnc may be a crucial factor in the development of early peritoneal endometriosis.

Abstract
The uterus-lining endometrium is essential to mammalian reproduction, receiving and accommodating the embryo for proper development. Despite its key role, mechanisms underlying endometrial biology (menstrual cycling, embryo interaction) and disease are not well understood. Its hidden location in the womb, and thereby-associated lack of suitable research models, contribute to this knowledge gap. Recently, 3D organoid models have been developed from both healthy and diseased endometrium. These organoids closely recapitulate the tissue's epithelium phenotype and (patho)biology, including in vitro reproduction of the menstrual cycle. Typically, organoids are grown in a scaffold made of surrogate tissue extracellular matrix (ECM), with mouse tumor basement membrane extracts being the most commonly used. However, important limitations apply including their lack of standardization and xeno-derivation which strongly hinder clinical translation. Therefore, researchers are actively seeking better alternatives including fully defined matrices for faithful and efficient growth of organoids. Here, we summarize the state-of-the-art regarding matrix scaffolds to grow endometrium-derived organoids as well as more advanced organoid-based 3D models. We discuss remaining shortcomings and challenges to advance endometrial organoids toward defined and standardized tools for applications in basic research and translational/clinical fields.

Abstract
The current diagnostic and therapeutic strategies for endometriosis are limited. Although endometriosis is a benign condition, some of its traits, such as increased cell invasion, migration, tissue inflammation, and angiogenesis are similar to cancer. Here we explored the application of homing peptides for precision delivery of diagnostic and therapeutic compounds to endometriotic lesions. First, we audited a panel of peptide phages for the binding to the cultured immortalized endometriotic epithelial 12Z and eutopic stromal HESC cell lines. The bacteriophages displaying PL1 peptide that engages with angiogenic extracellular matrix overexpressed in solid tumors showed the strongest binding to both cell lines. The receptors of PL1 peptide, tenascin C domain C (TNC-C) and fibronectin Extra Domain-B (Fn-EDB), were expressed in both cells. Silver nanoparticles functionalized with synthetic PL1 peptide showed specific internalization in 12Z and HESC cells. Treatment with PL1-nanoparticles loaded with the potent antimitotic drug monomethyl auristatin E decreased the viability of endometriotic cells in 2D and 3D cultures. Finally, PL1-nanoparticless bound to the cryosections of clinical peritoneal endometriotic lesions in the areas positive for TNC-C and Fn-EDB immunoreactivities and not to sections of normal endometrium. Our findings suggest potential applications for PL1-guided nanoparticles in precision diagnosis and therapy of endometriosis.

Fibronectin Molecular Status in Plasma of Women with Endometriosis and Fertility Disorders. Int J Mol Sci 2021; 22:ijms222111410.

Abstract
The diagnosis of endometriosis and fertility disorders is difficult; therefore, it is necessary to look for reliable biomarkers. Analysis of the molecular status of fibronectin as a key player in repair and wound healing processes, as well as in coagulation and fibrinolysis pathways, is justified. ELISA and SDS-agarose immunoblotting were applied to determine the fibronectin concentration and presence and occurrence of soluble FN-fibrin complexes in the blood plasma of women with endometriosis (n = 38), fertility disorders (n = 28) and the healthy group (n = 25). The concentration of fibronectin in the blood plasma of women with endometriosis (292.61 ± 96.17 mg/L) and fertility disorders (287.53 ± 122.68 mg/L) was significantly higher than in the normal group (226.55 ± 91.98 mg/L). The presence of FN-fibrin complexes of 750, 1000, 1300, 1600 and 1900 kDa in the plasma of women with endometriosis and fertility disorders was shown. The presence of FN-fibrin complexes with a molecular mass of more than 1300 kDa in women with endometriosis and infertility and the complete absence of these complexes in healthy women may indicate an increased and chronic activation of coagulation mechanisms in these patients. The presence of complexes of high molecular mass may be one of the biomarkers of fertility disorders in women.

Abstract
Previously, we reported that endometrial stromal (ES) and endometrial epithelial (EE) cells did not attach to tenascin C, indicating the absence of active integrin α9β1 on the surface of mouse ES and EE cells. However, that study used recombinant tenascin C without fibronectin (FN) type III repeats interacting with integrin heterodimers. Therefore, we re-evaluated the presence of integrin α9β1 actively functioning on the surface of mouse ES and EE cells using full-length native tenascin C with FN type III repeats. The functionality of integrin α9β1 was confirmed using attachment and antibody inhibition assays. Both mouse ES and EE cells showed significantly increased adhesion to native tenascin C, and functional blocking of integrin α9β1 significantly inhibited adhesion to native tenascin C. These results demonstrate that the integrin α9 and β1 subunits function as active heterodimers on the plasma membrane of mouse ES and EE cells, respectively.

Tissue-specific decellularized endometrial substratum mimicking different physiological conditions influences in vitro embryo development in a rabbit model. Acta Biomater 2019; 89:126-138.

Abstract
In the last decades, the decellularization (DC) of organs has become an established technique in the field of regenerative medicine to yield complex and vascularized bioscaffolds. Furthermore, it has been demonstrated in vitro that these decellularized scaffolds retain their native tissue-specificity. This is also the case when this tissue-specific extracellular matrix (ECM) is solubilized and used as hydrogels or coatings to create a biomimetic environment. In this study we investigated if this specificity not only remains when applied to distinct tissues but even more, that these differences can be distinguished within the same tissue at different stages of proliferation. To address this question, a sensitive in vitro animal model was used: rabbit embryos at the third day of development were cultured on coatings made from acellular endometrium that was non-proliferating (non-synchronous, NS) and proliferating (synchronous with the embryo, S) and their development was compared. For this, we obtained whole NS and S rabbit uteri and subjected them to an adapted decellularization protocol. The acellular endometrium was carefully separated by microdissection and converted into a pre-gel solution to be used as hydrogels and coatings for in vitro assays. First, the characteristics of these NS and S hydrogels were investigated by proteomic analysis, electron microscopy and gelling kinetics. When used as substrata for day 3 embryos culture, it became apparent that only the acellular ECM from synchronous endometrial coating achieved similar results to the gold standard culture protocols and conditions, possibly because of the slow release of growth factors present in the synchronous/proliferating endometrium. STATEMENT OF SIGNIFICANCE: It has been shown by in vitro culture of stem cells, progenitor cells and primary culture cells that decellularized tissues retain their specific functions and biochemical and structural compositions. The present work demonstrates that using a mild SDS and perfusion based decellularization (DC) protocol not only effectively decellularize whole rabbit uteri, adding to the growing field of reproductive tissue engineering, but more importantly that the differences in the proliferating endometrium are translated after DC. This implies that DC not only retains the interspecificity of tissues but also the intraspecificity of a developing hormonally stimulated tissue. For the first time, we demonstrate that the coating from decellularized synchronous endometrium acts as a biological support for in vitro embryo development, achieving comparable results with the current gold standard that only uses serum-containing media.

Abstract
Background Endometriosis is a common gynaecological disorder affecting 5-10% of women of reproductive age who often experience chronic pelvic pain and infertility. Definitive diagnosis is through laparoscopy, exposing patients to potentially serious complications, and is often delayed. Non-invasive biomarkers are urgently required to accelerate diagnosis and for triaging potential patients for surgery. Methods This retrospective case control biomarker discovery and validation study used quantitative 2D-difference gel electrophoresis and tandem mass tagging-liquid chromatography-tandem mass spectrometry for protein expression profiling of eutopic and ectopic endometrial tissue samples collected from 28 cases of endometriosis and 18 control patients undergoing surgery for investigation of chronic pelvic pain without endometriosis or prophylactic surgery. Samples were further sub-grouped by menstrual cycle phase. Selected differentially expressed candidate markers (LUM, CPM, TNC, TPM2 and PAEP) were verified by ELISA in a set of 87 serum samples collected from the same and additional women. Previously reported biomarkers (CA125, sICAM1, FST, VEGF, MCP1, MIF and IL1R2) were also validated and diagnostic performance of markers and combinations established. Results Cycle phase and endometriosis-associated proteomic changes were identified in eutopic tissue from over 1400 identified gene products, yielding potential biomarker candidates. Bioinformatics analysis revealed enrichment of adhesion/extracellular matrix proteins and progesterone signalling. The best single marker for discriminating endometriosis from controls remained CA125 (AUC = 0.63), with the best cross-validated multimarker models improving the AUC to 0.71-0.81, depending upon menstrual cycle phase and control group. Conclusions We have identified menstrual cycle- and endometriosis-associated protein changes linked to various cellular processes that are potential biomarkers and that provide insight into the biology of endometriosis. Our data indicate that the markers tested, whilst not useful alone, have improved diagnostic accuracy when used in combination and demonstrate menstrual cycle specificity. Tissue heterogeneity and blood contamination is likely to have hindered biomarker discovery, whilst a small sample size precludes accurate determination of performance by cycle phase. Independent validation of these biomarker panels in a larger cohort is however warranted, and if successful, they may have clinical utility in triaging patients for surgery.

Abstract
BACKGROUND A substantial body of studies supports the view that molecular and cellular features of endometriotic lesions differ from those of eutopic endometrium. Apart from that, evidence exists that the eutopic endometrium from pa-tients with endometriosis differs from that of females without endometriosis. OBJECTIVE Aberrant expression profiles include a number of non-steroid signaling pathways that exert their putative influ-ence on the pathogenesis of endometriosis at least in part via crosstalk(s) with estrogen-mediated mechanisms. A rational to focus research on non-steroid signal pathways is that they might be remunerative targets for the development and selection of novel therapeutics to treat endometriosis possibly without affecting estrogen levels. RESULTS AND CONCLUSION In this article, we describe molecular and cellular features of endometriotic lesions and focus on the canonical WNT/β-signaling pathway, a key regulatory system in biology (including stem cell homeostasis) and often in pathophysiological conditions such as endometriosis. Recently emerged novel biological concepts in signal transduction and gene regulation like exosomes and microRNAs are discussed in their putative role in the pathogenesis of endometriosis.

Abstract
STUDY QUESTION How does progesterone alter matrix remodeling in abdominal wall endometriomas compared with normal endometrium? SUMMARY ANSWER Progesterone may prevent attachment of endometrial cells to the abdominal wall, but does not ameliorate abnormal stromal cell responses of abdominal wall endometriomas. WHAT IS KNOWN ALREADY Menstruation is a tightly orchestrated physiologic event in which steroid hormones and inflammatory cells cooperatively initiate shedding of the endometrium. Abdominal wall endometriomas represent a unique form of endometriosis in which endometrial cells inoculate fascia or dermis at the time of obstetrical or gynecologic surgery. Invasion of endometrium into ectopic sites requires matrix metalloproteinases (MMPs) for tissue remodeling but endometrium is not shed externally. STUDY DESIGN SIZE, DURATION Observational study in 14 cases and 19 controls. PARTICIPANTS /MATERIALS, SETTING, METHODS Tissues and stromal cells isolated from 14 abdominal wall endometriomas were compared with 19 normal cycling endometrium using immunohistochemistry, quantitative PCR, gelatin zymography and cell attachment assays. P values < 0.05 were considered significant and experiments were repeated in at least three different cell preps to provide scientific rigor to the conclusions. MAIN RESULTS AND THE ROLE OF CHANCE The results indicate that MMP2 and MMP9 are not increased by TGFβ1 in endometrioma stromal cells. Although progesterone prevents attachment of endometrioma cells to matrix components of the abdominal wall, it does not ameliorate these abnormal stromal cell responses to TGFβ1. LARGE SCALE DATA N/A. LIMITATIONS REASONS FOR CAUTION Endometriomas were collected from women identified pre-operatively. Not all endometriomas were collected. Stromal cells from normal endometrium were from different patients, not women undergoing endometrioma resection. WIDER IMPLICATIONS OF THE FINDINGS This work provides insight into the mechanisms by which progesterone may prevent abdominal wall endometriomas but, once established, are refractory to progesterone treatment. STUDY FUNDING/COMPETING INTEREST(S) Tissue acquisition was supported by NIH P01HD087150. Authors have no competing interests.

Abstract
Smooth muscle metaplasia (SMM) and fibrotic tissues are frequently seen in endometriotic lesions, yet the mechanisms underlying their formation are poorly understood. In this study, we investigated the roles of activated platelets in driving epithelial-mesenchymal transition (EMT) and fibroblast-to-myofibroblast transdifferentiation (FMT) in endometriosis. Through in vitro experimentations, we found that activated platelets, through the release of TGF-β1 and the induction of TGF-β/Smad signaling pathway, promoted EMT and FMT in endometriosis, resulting in increased cell contractility, collagen production, and ultimately to fibrosis. TGF-β blockade reversed these processes. Prolonged exposure of endometriotic stromal cells to activated platelets induced increased expression of α-SMA as well as markers of differentiated smooth muscle cells. Consequently, endometriotic lesions and their microenvironment contain all the necessary molecular machinery to promote SMM and fibrogenesis. Our results suggest that endometriotic lesions are wounds that undergo repeated injury and healing, highlighting the importance of platelets in the development of endometriosis.

Abstract
BACKGROUND The pathogenesis and etiology of endometrial polyps has not been elucidated. In this study, we aimed to examine the pathogenic mechanisms of endometrial polyp development using immunohistochemistry. We evaluated the expression of galectin-3 and cyclooxgenase-2 (COX-2) during the menstrual cycle in premenopausal women with endometrial polyps or normal endometrium. METHODS Thirty-one patients with endometrial polyps and 50 healthy control patients were included in this study. The levels of expression of COX-2 and galectin-3 were studied by immunohistochemistry. RESULTS The percentage of COX-2-positive cells and the intensity of COX-2 staining in the endometrium did not vary during the menstrual cycle either in the control group or in patients with endometrial polyps. However, expression of galectin-3 was significantly lower in endometrial polyps and during the proliferative phase of the endometrium compared with the secretory phase. CONCLUSIONS Our data suggests that the pathogenesis of endometrial polyps does not involve expression of COX-2 or galectin-3.

Abstract
Endometriosis is a chronic disease in which epithelial and stromal cells that resemble the eutopic endometrium are found in ectopic lesions. In order to examine how microenvironmental factors such as extracellular matrix and macrophages influence disease progression, 12Z (an immortalized ectopic epithelial cell line) were cultured on tissue culture plastic (TCP) or in gels of recombinant basement membrane (rBM) or collagen I. Unlike cells in other conditions, cells in rBM formed multi-cellular structures in a 67 kDa non-integrin laminin receptor (67LR)-dependent manner. To examine the impact of macrophage-secreted factors on cell behavior, 12Z cells on all three substrates were treated with conditioned media from differentiated THP-1 (an immortalized monocytic cell line). Significant proliferation and invasion was observed only with cells cultured in rBM, indicating that extracellular matrix cues help dictate cell response to soluble signals. Cells cultured on rBM were then treated with individual cytokines detected in the conditioned media, with increased proliferation observed following exposure to interleukin-8 (CXCL8/IL-8) and both increased proliferation and invasion following treatment with heparin-binding EGF-like growth factor (HB-EGF). This study suggests that rBM gels can be used to induce in vitro lesion formation in order to identify soluble factors that influence proliferation and invasion.

Abstract
Endometriosis, PCOS, and unexplained infertility are currently the most common diseases rendering large numbers of women infertile worldwide. Oxidative stress, due to its deleterious effects on proteins and nucleic acids, is postulated to be the one of the important mechanistic pathways in differential expression of proteins and in these diseases. The emerging field of proteomics has allowed identification of proteins involved in cell cycle, as antioxidants, extracellular matrix (ECM), cytoskeleton, and their linkage to oxidative stress in female infertility related diseases. The aim of this paper is to assess the association of oxidative stress and protein expression in the reproductive microenvironments such as endometrial fluid, peritoneal fluid, and follicular fluid, as well as reproductive tissues and serum. The review also highlights the literature that proposes the use of the fertility related proteins as potential biomarkers for noninvasive and early diagnosis of the aforementioned diseases rather than utilizing the more invasive methods used currently. The review will highlight the power of proteomic profiles identified in infertility related disease conditions and their linkage with underlying oxidative stress. The power of proteomics will be reviewed with regard to eliciting molecular mechanisms for early detection and management of these infertility related conditions.

Abstract
OBJECTIVE This prospective study was designed to determine whether the expression of cyclooxygenase-2 (COX-2) and vascular endothelial growth factor (VEGF) in the endometrial tissue obtained from the peri-implantation period of women with endometrial polyp (EP) differs from that of control subjects without a polyp. METHODS Endometrial samples were collected from 30 patients with EP and 30 control subjects without EP, in the mid-secretory phase. The expression of COX-2 and VEGF in the endometrium was examined with the use of immunohistochemistry. RESULTS COX-2 and VEGF were predominantly expressed in endometrial glands. The expression of COX-2 and VEGF in the endometrium obtained from women with EP was lower than that of control subjects. CONCLUSION The reduced expression of COX-2 and VEGF in the endometrium of women with EP may account for the association between EP and infertility.

Abstract
BACKGROUND Endometrial cells, which are shed by retrograde menstruation, may aberrantly express molecules involved in invasion and migration, leading to endometriosis. The aim of this study was to investigate the expression of the laminin gamma 2 chain (LAMC2) in the tissues of women with and without endometriosis. METHODS Endometrial biopsy specimens were collected from healthy volunteers and from endometriosis patients. Biopsy specimens from the corresponding endometriotic lesions were also collected. The expression of laminin gamma 2 chain was evaluated by immunohistochemistry and reverse transcription polymerase chain reaction (RT-PCR). RESULTS Endometrial tissue from women with or without endometriosis showed constitutive expression of LAMC2 mRNA throughout the menstrual cycle. A higher mRNA level was observed in ectopic endometrium (Ec) from women with endometriosis compared with eutopic endometrium (Eu) from women with endometriosis. Immunohistochemistry revealed a varied pattern of laminin gamma 2 chain expression, with increased epithelial expression in eutopic endometrium from women with endometriosis compared with those without endometriosis. CONCLUSIONS The altered expression of laminin gamma 2 chain in eutopic endometrium from women with endometriosis may provide new opportunities for diagnosis and treatment.

Abstract
Background Among several theories explaining the pathogenesis of endometriosis, Sampson's theory seems to be the most reliable and popular. However, this theory does have some problems. First, the onset of endometriosis is not as common as retrograde menstruation. Second, the surface of the peritoneum is capable of preventing the adhesion of foreign bodies such as endometrial cells. Regarding the first problem, several studies on immunosurveillance have been reported. The second problems has not yet been clarified, Therefore we investigated the problem in the present report. Methods Levels of CD44 and tenascin in both menstrual and peripheral blood were assayed in 19 healthy volunteer women in the first experiment. In the second experiment, the effects of tenascin on the activity of MMP-9 were investigated, because the invasive ability of endometriotic cells is known to be due to MMP activity. Results CD44 and tenascin concentrations were significantly higher in menstrual blood than in peripheral blood. Since CD44 is a specific hyaluronic acid receptor, CD44 in menstrual blood was demonstrated to be a specific matchmaker of adhesion between the endometrial cells and the peritoneal surface. Tenascin in menstrual blood and endometriotic cells up-regulated MMP activity and promoted the invasive action of endometriotic cells. Conclusion The present study clarified that adhesion of endometrial cells in menstrual blood on adhesion-preventive peritoneal surface was achieved by a mediator, CD44, in menstrual blood and that the ability of endometriotic cells to invade, induced by MMP, was achieved through up-regulation of MMP activity by the mediator tenascin.

Abstract
OBJECTIVE Endometriosis is characterized by the ectopic growth of endometrial tissue. One of the first steps to the spread of endometriosis in the peritoneal cavity is the attachment of endometriotic cells to peritoneal surfaces after they have been released into the peritoneal fluid from pre-existing endometriotic lesions. The increased adhesive and proliferative potential of endometriotic cells in response to specific extracellular matrix (ECM) components has been suggested to contribute to the pathogenesis of endometriosis. STUDY DESIGN Adhesive properties of endometriotic stromal cells (ECSC) and normal eutopic endometrial cells (NESC) to various extracellular matrix proteins were investigated by in vitro cell adhesion assays. The expression levels of integrins in these cells were also examined by Western blot analysis. RESULTS Both ECSC and NESC significantly adhered to collagen type I and collagen type IV. ECSC revealed higher adhesive properties to these ECM proteins than NESC did. ECSC, but not NESC, adhered to fibronectin and laminin. Higher levels integrin of α1, α2, αv, β1, and β3 protein expression were observed in ECSC than in NESC. On the other hand, the levels of integrin α3 and αL proteins were lower in ECSC than in NESC. CONCLUSIONS The results suggest that endometriotic cells possess stronger adhesion to ECM proteins, and that increase may be mediated, in part, through integrins. These findings may elucidate one of the mechanisms underlying the formation of peritoneal endometriotic lesions.

Abstract
This study tested the hypothesis that reciprocal communication occurs between macrophages and cultured human endometrial stromal cells and that this communication may contribute to the pathology of endometriosis. An endometrial stromal cell line (telomerase-immortalized human endometrial stromal cell [T-HESC]) was treated with macrophage-conditioned medium (CM) +/- estradiol + progesterone. Macrophages were treated without or with T-HESC CM. DNA microarray identified 716 differentially expressed genes in T-HESCs in response to factors secreted by macrophages. Upregulated genes in T-HESC included interleukin 8 (IL-8)/chemokine (C-X-C motif) ligand 8 (CXCL8), matrix metalloproteinase 3 (MMP3), phospholamban, cysteine-rich angiogenic inducer 61 (CYR61), connective tissue growth factor (CTGF), tenascin C, and nicotinamide N-methyltransferase (NNMT), whereas integrin alpha-6 was downregulated. In contrast, 15 named genes were differentially expressed in macrophages in response to factors secreted by endometrial stromal cells. The data document reciprocal communication between macrophages and endometrial stromal cells and suggest that interaction with macrophages stimulates the expression of genes in endometrial stromal cells that may support the establishment of endometriosis.

Abstract
Intrinsic abnormalities in transplanted eutopic endometrium are believed to contribute to the pathogenesis of pelvic endometriosis. Herein we investigated transcriptomic differences in human endometrial stromal fibroblasts (hESFs) from women with (hESF(endo)) vs. without (hESF(nonendo)) endometriosis, in response to activation of the protein kinase A (PKA) pathway with 8-bromoadenosine-cAMP (8-Br-cAMP). hESF(nonendo) (n = 4) and hESF(endo) (n = 4) were isolated from eutopic endometrium and treated +/- 0.5 mm 8-Br-cAMP for 96 h. Purified total RNA was subjected to microarray analysis using the whole-genome Gene 1.0 ST Affymetrix platform. A total of 691 genes were regulated in cAMP-treated hESF(nonendo) vs. 158 genes in hESF(endo), suggesting a blunted response to cAMP/PKA pathway activation in women with disease. Real-time PCR and ELISA validated the decreased expression of decidualization markers in hESF(endo) compared with hESF(nonendo). In the absence of disease, 8-Br-cAMP down-regulated progression through the cell cycle via a decrease in cyclin D1, cyclin-dependent kinase 6, and cell division cycle 2 and an increase in cyclin-dependent kinase inhibitor 1A. However, cell cycle components in hESF(endo) were not responsive to 8-Br-cAMP, resulting in persistence of a proliferative phenotype. hESF(endo) treated with 8-Br-cAMP exhibited altered expression of immune response, extracellular matrix, cytoskeleton, and apoptosis genes. Changes in phosphodiesterase expression and activity were not different among experimental groups. These data support that eutopic hESF(endo) with increased proliferative potential can seed the pelvic cavity via retrograde menstruation and promote establishment, survival, and proliferation of endometriosis lesions, independent of hydrolysis of cAMP and likely due to an inherent abnormality in the PKA pathway.

Abstract
The pathophysiology of endometriosis remains unclear but involves a complex interaction between ectopic endometrium and host peritoneal tissues. We hypothesized that disruption of this interaction would suppress endometriotic lesion formation. We hoped to delineate the molecular and cellular dialogue between ectopic human endometrium and peritoneal tissues in nude mice as a first step toward testing this hypothesis. Human endometrium was xenografted into nude mice, and the resulting lesions were analyzed using microarrays. A novel technique was developed that unambiguously determined whether RNA transcripts identified via microarray analyses originated from human cells (endometrium) or mouse cells (mesothelium). Four key pathways (ubiquitin/proteasome, inflammation, tissue remodeling/repair, and ras-mediated oncogenesis) were revealed, demonstrating communication between host mesothelial cells and ectopic endometrium. Morphometric analysis of nude mouse lesions confirmed that necrosis, inflammation, healing and repair, and cell proliferation occurred during xenograft development. These processes were entirely consistent with the molecular networks revealed by the microarray data. The transcripts detected in the xenografts overlapped with differentially expressed transcripts in a comparison between paired eutopic and ectopic endometria from human endometriotic patients. For the first time, components of the interaction between ectopic endometrium and peritoneal stromal tissues are revealed. Targeted disruption of this dialogue is likely to inhibit endometriotic tissue formation and may prove to be an effective therapeutic strategy for endometriosis.

[PMID: 17681310 DOI: 10.1016/j.fertnstert.2007.05.028] [Citation(s) in RCA: 13] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/23/2006] [Revised: 05/11/2007] [Accepted: 05/11/2007] [Indexed: 10/23/2022]
Abstract
OBJECTIVE To investigate the localization of tenascin expression in the endometrium of women without endometriosis and in endometriotic implants, and to determine the in vitro regulation of tenascin by E(2) in these tissues. DESIGN Experimental laboratory study. SETTING University medical center. PATIENT(S) Reproductive age women with or without endometriosis. INTERVENTION(S) Proliferative (n = 14), and secretory (n = 14) endometrium from women without endometriosis and endometriosis implants (n = 14) were used for immunohistochemical analysis. Endometrial and endometriotic stromal cells were grown in culture and treated with E(2), the estrogen receptor antagonist ICI 182 780 (ICI) alone, E(2) in combination with ICI, or vehicle (control) for 24 hours, and tenascin expression was analyzed by Western blotting. MAIN OUTCOME MEASURE(S) Expression levels of tenascin in normal endometrium and endometriotic implants and its regulation by E(2). RESULT(S) Tenascin immunostaining revealed an increasing intensity in the stromal cells, starting from normal secretory endometrium, then normal proliferative endometrium, and reaching the highest expression in endometriotic implants. Estradiol induced a significant increase in tenascin protein levels in the endometriotic stromal cells in culture. CONCLUSION(S) The modulation of tenascin as an extracellular matrix protein by E(2) in endometriotic stromal cells may be one of the factors playing a role in the development of endometriosis.

Abstract
OBJECTIVE To validate a rat model of endometriosis using complimentary DNA (cDNA) microarrays by identifying common gene expression patterns between experimental and natural disease. DESIGN Autotransplantation rat model. SETTING Medical school department. ANIMALS Female Sprague-Dawley rats. INTERVENTION(S) Endometriosis was surgically induced by suturing uterine horn implants next to the small intestine's mesentery. Control rats received sutures with no implants. After 60 days, endometriotic implants and uterine horn were obtained. MAIN OUTCOME MEASURE(S) Gene expression levels determined by cDNA microarrays and real-time quantitative polymerase chain reaction (qPCR). The Cy5-labeled cDNA was synthesized from total RNA obtained from endometriotic implants. The Cy3-labeled cDNA was synthesized using uterine RNA from a control rat. Gene expression levels were analyzed after hybridizing experimental and control labeled cDNA to PIQOR (Parallel Identification and Quantification of RNAs) Toxicology Rat Microarrays (Miltenyi Biotec, Cologne, Germany) containing 1,252 known genes. The Cy5/Cy3 ratios were determined, and genes with >2-fold higher or <0.5-fold lower expression levels were selected. Microarray results were validated by QRT-PCR. RESULT(S) We observed differential expression of genes previously shown to be up-regulated in patients, including growth factors, inflammatory cytokines/receptors, tumor invasion/metastasis factors, adhesion molecules, and antiapoptotic factors. CONCLUSION(S) This study presents evidence in support of using this rat model to study the natural history of endometriosis and to test novel therapeutics for this incurable disease.

Abstract
OBJECTIVE To use DNA microarrays to identify differentially expressed genes in eutopic endometrium compared with ectopic endometrium. DESIGN Prospective, cross-sectional, observational study. SETTING University Medical Center and Research Laboratory. PATIENT(S) Eleven women with endometriosis. INTERVENTION(S) None. MAIN OUTCOME MEASURE(S) Differential gene expression. RESULT(S) Seven hundred seventeen of the 53,000 probes on the whole human DNA microarrays were changed by twofold or greater in ectopic versus eutopic endometrium. Families of genes that were expressed differentially include genes that code for proteins associated with the immune system and inflammatory pathways, cell adhesion, cell-cell junctions, the extracellular matrix and its remodeling, cytoskeletal proteins, and signal transduction pathway components, among others. CONCLUSION(S) The altered immune environment may allow survival of endometriotic cells that enter the abdominal cavity. Alterations of cell adhesion-associated genes may contribute to the adhesive and invasive properties of ectopic endometrium, and changes in signal transduction pathways support a change in the communication among cells of the endometrial explant compared with eutopic endometrium. These families of differentially expressed genes provide multiple opportunities for the development and testing of new hypotheses regarding endometriosis.

Abstract
OBJECTIVE To observe the effects of matrine on proliferation and apoptosis of human renal cell carcinoma cell line GRC-1 in vitro, and to explore its mechanism. METHODS The human renal cell carcinoma cell line GRC-1 was treated with matrine of different concentrations for 24, 48, 72 and 96 h respectively. The MTT assay was used to evaluate the cytotoxic effects of matrine on GRC-1 cells. The transmission electron microscope and flow cytometry were utilized to observe and detect the apoptosis of GRC-1 cells induced by matrine. The expression levels of Bcl-2 and Bax proteins were evaluated by streptavidin-biotin-peroxidase method. RESULTS The matrine of different concentrations all have cytotoxic effects on GRC-1 cells, with obvious dose- and time-dependent effects. The apoptosis induced by matrine was confirmed in GRC-1 cells. With intervention of matrine (1.5 g/L) for 12 h, the expression level of Bcl-2 in GRC-1 cells was decreased while the expression level of Bax was increased as compared with those in the untreated group. CONCLUSION The proliferation-inhibiting effects of matrine on human renal cell carcinoma cell line GRC-1 may be related to down-regulating the ratio of Bcl-2/Bax protein expression and promoting the apoptosis.

Abstract
Fibulin-1 is a secreted protein associated with elastic matrix fibres and basement membranes. It plays a role in stabilizing blood vessels and can also regulate cell motility and invasiveness. We studied the regulation of the fibulin-1 gene in the rat and human endometrium, an organ where cyclic tissue remodeling and angiogenesis take place. The rat fibulin-1C and -1D-specific DNA sequences were first identified and a comparison of the deduced amino acid sequence with the mouse and human counterparts showed a very strong conservation. The exon-intron structure was also maintained. Primers were derived for RT-PCR analysis of fibulin-1 expression in rat endometrium. The highest levels of fibulin-1C and -1D transcripts were measured at metestrous and diestrous, and in early pregnancy at day 3 post-coitum. In vivo studies showed stimulation of endometrial fibulin-1D expression after estrogen application, an effect prevented by parallel treatment with progesterone. Analysis of human endometrial tissues indicated that the fibulin-1D transcript levels were higher during the mid-secretory phase than during the proliferative and early secretory phases. Cultured human endometrial stromal cells treated with progesterone responded with a dramatic increase of fibulin-1 protein expression. This was enhanced by parallel treatment with epidermal growth factor and prevented by application of the antiprogestin RU486. Altogether the results show a cycle-dependent regulation of endometrial fibulin-1 expression controlled by both progesterone and estrogen. Based on its implication in tissue remodeling and angiogenesis, fibulin-1 may play an important role in endometrial receptivity for embryo implantation.

Abstract
OBJECTIVE Sampson's theory of reflux menstruation suggests that endometriosis is one form of a condition known as an autotransplant. This study seeks to characterize autotransplants as they are described in the literature and to determine whether endometriosis resembles an autotransplant. DESIGN Literature review of published studies containing the following types of information: [1] characterization of the histologic features, immunohistochemistry, or structural function of autotransplants; and [2] comparisons of endometriosis with endometrium. MAIN OUTCOME MEASURE(S) Characteristics of multiple types of autotransplants were noted. Similarity or dissimilarity of endometriosis and endometrium was tabulated to judge qualitatively whether the bulk of the evidence supports the notion that endometriosis is an autotransplant. RESULT(S) Autotransplants remain very similar or identical to eutopic tissues of origin, regardless of the length of time following autotransplantation. Endometriosis differs in many profound and fundamental ways from eutopic endometrium, including clonality of origin, enzymatic activity, protein expression, and histologic and morphologic characteristics. A minority of studies has found similarities between endometriosis and eutopic endometrium. CONCLUSION(S) Endometriosis is dissimilar to eutopic endometrium and therefore lacks characteristics of an autotransplant. Sampson's theory of origin of endometriosis is not supported by the results of this study. Studies of experimental endometriosis that have not used menstrual endometrium may be misleading.

Abstract
We performed a case-controlled study to study the immunoreactivity patterns and staining intensity of alphavbeta5 and alphavbeta6 integrins in ectopic and eutopic endometrium from women with endometriosis and compared them with those in normal control endometrium. Forty eutopic and ectopic samples from patients with endometriosis were compared with 12 control endometrial samples. Staining was evaluated using a computerized image analysis system by a blinded, independent observer. The immunoreactivity patterns for both alphavbeta5 and alphavbeta6 were very similar. In eutopic endometrium from women with or without endometriosis, the immunostaining intensity score for both integrins was stronger during the secretory than the proliferative phase. Immunoreactivity in endometriosis was greater than in eutopic endometrium. There were no significant menstrual cycle-related staining differences in endometriosis. The percentage of blood vessels immunolabeled was greater in endometriosis than eutopic endometrium from endometriosis patients and greater in eutopic endometrium from these patients compared with control endometrium. Ectopic tissue from patients with stages I and II endometriosis showed significantly higher staining intensity than ectopic tissue from patients with stages III and IV disease. Determination of the specific functional consequences of the differences observed in alphavbeta5 and alphavbeta6 integrin immunostaining may provide an increased understanding regarding the pathogenesis of endometriosis.

Abstract
Tenascin (TN) is an extracellular matrix glycoprotein (ECM) that participates in embryogenesis and carcinogenesis. The aim of this study was to investigate immunohistochemically the expression of TN in the normal, hyperplastic, and neoplastic endometrium (endometrial adenocarcinoma). In the adenocarcinomas, the results were correlated with patient age, menopausal status, stage, grade, myometrial invasion, and vascular invasion. TN expression was studied in the following cases: proliferative endometrium (10 cases), early secretory endometrium (10), secretory endometrium (10), simple hyperplasia (15), complex hyperplasia (15), atypical hyperplasia (15), and endometrial adenocarcinomas (25). Staining of basal membranes and the cytoplasm of the stromal and epithelial cells was evaluated semiquantitatively. Positive staining was observed in the vascular and glandular basal membranes, stromal cells, and epithelial cells of proliferative, hyperplastic, and neoplastic endometrium. The difference in percentage of stained stromal cells between the neoplastic and the nonneoplastic (proliferative and hyperplastic) endometrium was significant (p<0.005). However, the percentage of stained epithelial cell area in hyperplasia was significantly higher than that of adenocarcinoma and functional endometrium (p<0.005). We conclude that TN is an extracellular matrix glycoprotein that plays a role in proliferation and possibly endometrial carcinogenesis.

Abstract
The uterus contains all the components of a tertiary lymphoid compartment. We hypothesize that specific leukocyte recruitment to the endometrium during the secretory phase of the menstrual cycle and early pregnancy limits the type of immunocyte that gains access. The present study utilized flow cytometry to define and quantify adhesion molecules possibly used by decidual infiltrating lymphocytes (DIL) as homing receptors, uterine microvascular myometrial endothelial cells (UtMVE-Myo) as addressins, and secretory endometrial stroma cells (STO) as retainment factors. Human umbilical cord vein endothelial cells and peripheral blood lymphocytes were used as control cells for comparison studies. DIL were composed of predominantly lymphocyte function-associated antigen (LFA)-1+, intercellular adhesion molecule (ICAM)-1+, LFA-2+, LFA-3+, gp150,95+, alpha1beta1+, Hermes cell adhesion molecule (H-CAM)+, and neural cell adhesion molecule (N-CAM)+ (CD56(bright)) memory/effector natural killer cells. A significant number of UtMVEC-Myo expressed platelet endothelial cell adhesion molecule (PECAM)-1, a percentage were uniquely LFA-3+, and alpha4 integrin expression was uniquely high. An increased number of STO uniquely expressed alpha3, beta3, and LFA-3, whereas alpha2, alpha4, alphaVbeta3, and H-CAM were significantly increased. Possible unique adhesions of DIL:UtMVEC-Myo included SLe(x):PECAM, vascular cell adhesion molecule-1:alpha4, and LFA-2:LFA-3, whereas DIL:STO included LFA-2:LFA-3 and N-CAM:N-CAM. Unique molecules on DIL may also associate with extracellular matrix (ECM) or complement on UtMVEC-Myo or STO to form gp150,95:fibrinogen/iC3b/C3dg, alpha1beta1:laminin (LM)/collagen (CO), and ICAM-1:fibronectin (FN) interactions. Bridges of ECM may also form between DIL and UtMVEC-Myo adhesion molecules including ICAM-1:FN:ICAM-1 and alpha4beta1:FN:alpha4beta1. DIL:ECM:STO interactions may involve alpha2beta1:CO:alpha2beta1, alpha3beta1:LM/CO/FN:alpha3beta1, alphaVbeta3:VN:alphaVbeta3, and H-CAM:hyaluronate:H-CAM. It is likely that many adhesion molecules play a role in the recruitment and retainment of specialized lymphocytes within the uterine microenvironment. (Mackay et al., 1990).
