Reprod Biomed Online 2016; 32:434-45. [PMID: 26854065 DOI: 10.1016/j.rbmo.2015.12.013] [Citation(s) in RCA: 64] [Impact Index Per Article: 8.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/30/2015] [Revised: 12/18/2015] [Accepted: 12/22/2015] [Indexed: 02/06/2023]
Abstract
Endometriosis is characterized by growth of endometrial tissue at ectopic locations. Down-regulation of microRNA miR-200b is observed in endometriosis and malignant disease, driving tumour cells towards an invasive state by enhancing epithelial-to-mesenchymal transition (EMT). miR-200b up-regulation may inhibit EMT and invasive growth in endometriosis. To study its functional impact on the immortalized endometriotic cell line 12Z, the stromal cell line ST-T1b, and primary endometriotic stroma cells, a transient transfection approach with microRNA precursors was employed. Expression of bioinformatically predicted targets of miR-200b was analysed by qPCR. The cellular phenotype was monitored by Matrigel invasion assays, digital-holographic video microscopy and flow cytometry. qPCR revealed significant down-regulation of ZEB1 (P < 0.05) and ZEB2 (P < 0.01) and an increase in E-cadherin (P < 0.01). miR-200b overexpression decreased invasiveness (P < 0.0001) and cell motility (P < 0.05). In contrast, cell proliferation (P < 0.0001) and the stemness-associated side population phenotype (P < 0.01) were enhanced following miR-200b transfection. These properties were possibly due to up-regulation of the pluripotency-associated transcription factor KLF4 (P < 0.05) and require attention when considering therapeutic strategies. In conclusion, up-regulation of miR-200b reverts EMT, emerging as a potential therapeutic approach to inhibit endometriotic cell motility and invasiveness.

Iron overload-modulated nuclear factor kappa-B activation in human endometrial stromal cells as a mechanism postulated in endometriosis pathogenesis. Fertil Steril 2014; 103:439-47. [PMID: 25500022 DOI: 10.1016/j.fertnstert.2014.10.046] [Citation(s) in RCA: 26] [Impact Index Per Article: 2.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/03/2014] [Revised: 10/19/2014] [Accepted: 10/24/2014] [Indexed: 12/27/2022]
Abstract
OBJECTIVE To evaluate the effect of iron overload on nuclear factor kappa-B (NF-κB) activation in human endometrial stromal cells (ESCs). DESIGN Experimental study. SETTING University hospital research laboratory. PATIENT(S) Ten healthy women. INTERVENTION(S) Isolated ESCs from endometrial biopsies were incubated with 50 μM FeSO(4) or vehicle. The NF-κB inhibitor [5-(p-fluorophenyl)-2-ureido] thiophene-3-carboxamide (TPCA-1), which inhibits IKKβ, the kinase of IκBα (inhibitory protein of NF-κB), was used to prevent iron overload-stimulated NF-κB changes in ESCs. MAIN OUTCOME MEASURE(S) NF-κB activation was assessed by p65:DNA-binding activity immunodetection assay. IκBα, p65, and intercellular adhesion molecule (ICAM)-1 proteins expression was evaluated by Western blots. ESC soluble ICAM (sICAM)-1 secretion was measured by ELISA using conditioned medium. RESULT(S) Iron overload increased p65:DNA-binding activity and decreased IκBα and p65 cytoplasmic expression in ESCs after 30 minutes of incubation as compared with the basal condition. ESC ICAM-1 expression and sICAM-1 secretion were higher after 24 hours of iron overload treatment than in the absence of treatment. TPCA-1 prevented the iron overload-induced increase of p65:DNA binding and IκBα degradation. CONCLUSION(S) Iron overload activates IKKβ in ESCs, stimulating the NF-κB pathway and increasing ICAM-1 expression and sICAM-1 secretion. These results suggest that iron overload induces a proendometriotic phenotype on healthy ESCs, which could participate in endometriosis pathogenesis and development.

Abstract
OBJECTIVE To harmonize standard operating procedures (SOPs) and standardize the recording of associated data for collection, processing, and storage of human tissues relevant to endometriosis. DESIGN An international collaboration involving 34 clinical/academic centers and three industry collaborators from 16 countries on five continents. SETTING In 2013, two workshops were conducted followed by global consultation, bringing together 54 leaders in endometriosis research and sample processing from around the world. PATIENT(S) None. INTERVENTION(S) Consensus SOPs were based on: 1) systematic comparison of SOPs from 24 global centers collecting tissue samples from women with and without endometriosis on a medium or large scale (publication on >100 cases); 2) literature evidence where available, or consultation with laboratory experts otherwise; and 3) several global consultation rounds. MAIN OUTCOME MEASURE(S) Standard recommended and minimum required SOPs for tissue collection, processing, and storage in endometriosis research. RESULT(S) We developed "recommended standard" and "minimum required" SOPs for the collection, processing, and storage of ectopic and eutopic endometrium, peritoneum, and myometrium, and a biospecimen data collection form necessary for interpretation of sample-derived results. CONCLUSION(S) The EPHect SOPs allow endometriosis research centers to decrease variability in tissue-based results, facilitating between-center comparisons and collaborations. The procedures are also relevant to research into other gynecologic conditions involving endometrium, myometrium, and peritoneum. The consensus SOPs are based on the best available evidence; areas with limited evidence are identified as requiring further pilot studies. The SOPs will be reviewed based on investigator feedback and through systematic triannual follow-up. Updated versions will be made available at: http://endometriosisfoundation.org/ephect.

[PMID: 24462576 DOI: 10.1016/j.bbagen.2014.01.022] [Citation(s) in RCA: 25] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/05/2013] [Revised: 01/13/2014] [Accepted: 01/15/2014] [Indexed: 12/11/2022]
Abstract
BACKGROUND MicroRNAs are small noncoding RNAs which regulate gene expression at the posttranscriptional level by inducing mRNA degradation or translational repression. MicroRNA-dependent modulation of the extracellular matrix and its cellular receptors has emerged as a novel mechanism of regulating numerous matrix-dependent processes, including cell proliferation and apoptosis, cell adhesion and migration, cell differentiation and stem cell properties. SCOPE OF REVIEW In this review, we will present different mechanisms by which microRNAs and extracellular matrix constituents mutually regulate their expression, and we will demonstrate how these expression changes affect cell behavior. We will also highlight the importance of dysregulated matrix-related microRNA expression for the pathogenesis of inflammatory and malignant disease, and discuss the potential for diagnostic and therapeutic applications. MAJOR CONCLUSIONS MicroRNAs and matrix-dependent signal transduction processes form novel regulatory circuits, which profoundly affect cell behavior. As misexpression of microRNAs targeting extracellular matrix constituents is observed in a variety of diseases, a pharmacological intervention with these processes has therapeutic potential, as successfully demonstrated in vitro and in advanced animal models. However, a deeper mechanistic understanding is required to address potential side effects prior to clinical applications in humans. GENERAL SIGNIFICANCE A full understanding of the role and function of microRNA-dependent regulation of the extracellular matrix may lead to new targeted therapies and new diagnostics for malignant and inflammatory diseases in humans. This article is part of a Special Issue entitled Matrix-mediated cell behaviour and properties.

MicroRNA miR-145 inhibits proliferation, invasiveness, and stem cell phenotype of an in vitro endometriosis model by targeting multiple cytoskeletal elements and pluripotency factors. Fertil Steril 2013; 99:1346-1355.e5. [PMID: 23312222 DOI: 10.1016/j.fertnstert.2012.11.055] [Citation(s) in RCA: 76] [Impact Index Per Article: 6.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/10/2012] [Revised: 11/15/2012] [Accepted: 11/30/2012] [Indexed: 12/17/2022]
Abstract
OBJECTIVE To study the function of miR-145, known to be dysregulated in endometriosis, and to identify its target genes in an in vitro endometriosis model. DESIGN Experimental laboratory study. SETTING University medical centers. PATIENT(S) Primary endometrial stroma cells were derived from eutopic endometrium of three American Society for Reproductive Medicine stage III endometriosis patients and from ectopic lesions of four patients with deep infiltrating endometriosis. INTERVENTION(S) The human endometriotic cell line 12Z and primary eutopic and ectopic endometrial stroma cells were transiently transfected with miR-145 precursors or anti-miR-145 inhibitors and investigated for posttranscriptional regulation of predicted target genes and changes in cell behavior. MAIN OUTCOME MEASURE(S) Predicted target expression was measured by quantitative reverse transcription-polymerase chain reaction and Western blotting, and altered cell behavior was monitored by cell proliferation assays. The 12Z cells were additionally investigated by Matrigel invasion assays, cell cycle analysis, side population analysis, and aldehyde dehydrogenase activity assays. RESULT(S) In all cells investigated, miR-145 overexpression inhibited cell proliferation and induced down-regulation of FASCIN-1, SOX2, and MSI2. In 12Z cells miR-145 upregulation increased Matrigel invasiveness and reduced side population and aldehyde dehydrogenase-1 activity. Additional down-regulated targets in 12Z cells included OCT4, KLF4, PODXL, JAM-A, and SERPINE1/PAI-1. ACTG2 and TAGLN were up-regulated upon pre-miR-145 transfection. JAM-A, FASCIN-1, and PAI-I down-regulation in 12Z cells were confirmed by Western blotting. CONCLUSION(S) miR-145 inhibits endometriotic cell proliferation, invasiveness, and stemness by targeting multiple pluripotency factors, cytoskeletal elements, and protease inhibitors.

Abstract
OBJECTIVE To study the function of syndecan-1 (SDC1) and its potential regulator miR-10b in endometriosis. DESIGN Experimental laboratory study. SETTING University medical center. PATIENT(S) Not applicable. INTERVENTION(S) The human endometriotic cell line 12Z was transiently transfected with SDC1 small interfering RNA or miR-10b precursors and investigated for changes in cell behavior and gene expression. 12Z and primary eutopic endometrial stroma cells of two American Society for Reproductive Medicine class III endometriosis patients were transfected with miR-10b precursors to investigate posttranscriptional regulation of SDC1. MAIN OUTCOME MEASURE(S) Quantitative polymerase chain reaction, Western blotting, flow cytometry, 3' untranslated region luciferase assays, and zymography were used to measure miR-10b-dependent targeting of SDC1 and SDC1-dependent expression changes of proteases and interleukin-6. Altered cell behavior was monitored by Matrigel invasion assays, cell viability assays, and mitogen-activated protein kinase activation blots. RESULT(S) Knockdown of SDC1 inhibited Matrigel invasiveness by >60% but did not affect cell viability. Interleukin-6 secretion, matrix metalloproteinase-9 expression, and matrix metalloproteinase-2 activity were reduced, whereas plasminogen activator inhibitor-1 protein expression was up-regulated. miR-10b overexpression significantly down-regulated SDC1, reduced Matrigel invasiveness by 20% and cell viability by 14%, and decreased mitogen-activated protein kinase activation in response to hepatocyte growth factor. CONCLUSION(S) Syndecan-1, a target of miR-10b, inhibits epithelial endometriotic cell invasiveness through down-regulation of metalloproteinase activity and interleukin-6.
