Project description:Our understanding of molecular mechanisms contributing to the pathophysiology of endometriosis, and their upstream regulators, remains limited. Using a C57Bl/6 mouse model of endometriosis in which decidualized endometrial tissue fragments are transferred to subcutaneous sites in recipient mice to mimic endometriosis lesions, we have generated a comprehensive profile of gene expression in decidualized endometrial tissue (n=4), and endometriosis-like lesions at Day 7 (n=4) and Day 14 (n=4) of lesion formation. High throughput mRNA sequencing allowed identification of genes and pathways involved in the initiation and progression of endometriosis-like lesions. We found distinct patterns of gene expression with substantial differences between the lesions and the decidualized endometrium from which they arose, but no differentially expressed genes between the two lesion timepoints. The transcriptional changes at the outset of lesion formation indicated substantial upregulation of immune response-associated canonical pathways. Pathway enrichment analysis indicates multiple potential endogenous upstream regulators, and reveals multiple gene candidates not previously implicated in endometriosis lesion formation suggesting these mediators may have novel roles in disease progression. Collectively, the provided data will be a valuable resource to inform research on the molecular mechanisms contributing to endometriosis development.

Project description:Endometriosis -associated ovarian carcinoma (EAOC) is mostly malignant transformation from endometriomas. However, the endometriosis cancerogenesis remains to be established. Using spatial transcriptomic of human specimens of normal, endometriomas and EAOC, activation of Interleukin-17C (IL-17C) signaling is identified, with higher IL-17 receptor E (IL-17RE) expression in endometriotic cells, to be associated with cancerogenesis and which has no previous association with EAOC. Elevated IL-17C concentration is found in peritoneal fluid in women with ovarian cancer and IL-17RE-overexpressed endometriosis mice. In particular, IL-17C knockout reduces peritoneal fluid IL-17C concentration and inhibits ectopic lesion growth in endometriosis mice. Besides, the role of IL-17C in the endometriosis cancerogenesis was investigated by blocking the IL-17C/IL-17RE, modulating IL-17RE and neutralizing IL-17C in endometriotic cells, endometrial organoids and endometriosis mice. These data defined peritoneal fluid-mediated endometriosis cancerogenesis through IL-17C regulation and suggests that IL-17C/IL-17RE can thus potentially serve as novel targets for with high IL-17C.

Project description:Endometriosis is a debilitating and painful gynecological inflammatory disease affecting approximately 15% of women. Current treatments are ineffective for a significant fraction of patients, underscoring the need for new medical therapies with long-term benefits. Given the relevance of neuroimmune communication in different disease outcomes, we investigated the role of CGRP-mediated neuroimmune communication in endometriosis. We found that mouse and human endometriosis lesions contained CGRP and RAMP1. In mice, nociceptor ablation reduced pain, monocyte recruitment, and lesion size, suggesting that nociceptor activation and neuropeptide release contribute to endometriosis lesion growth and pain. In vitro, CGRP-induced pro-endometriosis macrophages (PEMs) showed impaired efferocytosis and supported endometrial cell growth in a RAMP1-dependent manner. Treatment with FDA-approved drugs that block CGRP-RAMP1 signaling reduced mechanical hyperalgesia, spontaneous pain, and lesion size in mice. Altogether, our data demonstrates the effectiveness, cellular mechanisms and pre-clinical safety of non-hormonal and non-opioid CGRP/RAMP1 blocking therapies, which may lead to clinical benefit for endometriosis patients.

Project description:The pathophysiology of endometriotic lesion development remains unclear but involves a complex interaction between ectopic endometrium and host peritoneal tissues. We hypothesised that disruption of this interaction was likely to 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 towards testing this hypothesis. Human endometrium was xenografted into nude mice and the resulting lesions were analysed using microarrays. A novel technique was developed that unambiguously determined whether RNA transcripts identified by the microarray analyses originated from human cells (endometrium) or mouse cells (stroma). Four key pathways (ubiquitin/proteosome, inflammation, tissue remodelling/repair and ras-mediated oncogenesis) were revealed, that demonstrated communication between host stromal 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 transcripts differentially expressed in a comparison between paired eutopic and ectopic endometrium from human endometriotic patients. For the first time components of the interaction between ectopic endometrium and peritoneal stromal tissues have been revealed in ectopic endometrial lesions. Targeted disruption of this dialogue is likely to disrupt endometriotic tissue formation and may prove to be an effective therapeutic strategy for endometriosis. Experiment Overall Design: Xenografts of human endometrium in nude mice hybridised to both human and mouse specific genechips. 2 biological replicates, at 3 time points. Control human endometrium and mouse pertioneum were hybridised to both human and mouse genechips

Project description:Endometriosis is a benign gynecological condition that causes significant morbidity due to reduced fertility, pelvic pain and inflammatory dysfunctions. High-fat dietary intake has been linked to higher systemic inflammation and oxidative stress, which are both features of women with endometriosis. We evaluated the effects of high-fat diet (HFD) on endometriosis progression using immunocompetent mouse model wherein ectopic lesion was induced in wildtype and kruppel-like factor 9 (KLF9)- null donor mice. Results showed that HFD leads to increased ectopic lesion numbers and higher body weight gain. The HFD-promotion of lesion establishment was associated with decreased stromal estrogen receptor 1 and progesterone receptor expression, increased macrophage infiltration, and enhanced expression of pro-inflammarory and pro-oxidative stress pathway genes. Further, lesion-bearing mice had higher peritoneal fluid TNF-α and elevated local/systemic redox status than control-fed mice.

Project description:Endometriosis, a benign inflammatory disease whereby endometrial-like tissue grows outside the uterus, is a risk factor for endometriosis-associated ovarian cancers. In particular, ovarian endometriomas, cystic lesions of deeply invasive endometriosis, are considered the precursor lesion for ovarian clear-cell carcinoma (OCCC). To explore the transcriptomic landscape, OCCC from women with pathology-proven concurrent endometriosis (n = 4) were compared to benign endometriomas (n = 4) by bulk RNA and small-RNA sequencing.

Project description:Endometriosis is a complex pathological condition in which multiple components are involved in the disease development and clinical outcome. Endometriosis is mainly an inflammatory codition estrogen-dependent, with unknown pathogenesis, that is characterized by dissemination of edometrium tissue in ectopic position (ovary or pelvic peritoneum). Two main theories rise the pathologic onset: the presence of retrograde menstruation and celomic metaplasia in the pelvic peritoneum, that can occur for development defects. Endometriosis is related not only to genetic or immunological changes and to environmental pollution factors, as the endocrine interferents. The disease phenotype results from multiple events (genetics and enviromental), thus it is difficult to find a single gene as causative while is more probable that a gene network/s might involved in the onset and mantainement of the disease state. The peculiarity of endometriosis rely on the tissue speificity manteinance in the ectopic position, where it responds to the hormone stimuli as the tissue in the eutopic position. In order to identify genes potentially involved in growth and mainteinance of the ectopic endometrium, we have profiled ectopic (8 samples) and eutopic endometrium (8 samples) from several affected woman in the proliferative phase. As control we used endometrium from normal health donors in the same phase (6 samples).
