Project description:The hypothesis that male michrochimerism in eutopic endometrium is a factor for endometriosis, as indicated by indirect evidence was examined in endometrial samples from control (Group 1) and stage IV ovarian endometriosis (Group 2), either fertile (Group 1A and 2A) or Infertile (Group 1B and 2B) pateints. 6 coding and 10 non-coding genes showed bi-modal pattern of expression characterised by low expression in samples obtained from fertile patients and high expressions in infertile patients. Several coding and non-coding MSY-linked genes displayed michrochimerism in form of presence of their respective DNA inserts along with their microarray-detectable expression in endometrium irrespective of fertility history and disease.

Project description:Analysis of endometriosis disease associated tissues, endometrium and peritoneum at gene expression level. In this study we present, an interactive web-based user interface for browsing gene expression patterns in the normal endometrium, peritoneum and endometriotic lesions. This tool allows users to explore gene expression profiles of genes of interests in the endometrium and different lesion types without the requirement of advanced computational skills.

Project description:The pathogenesis of endometriosis may result from aberrant angiogenesis that occurs in eutopic endometrium with retrograde menstruation. The difference in gene expression profile between human endometrial endothelial cells (HEECs) from eutopic endometria of patients with and without endometriosis would be determinant that affects the occurrence of endometriosis. To explore this kind of difference, we performed in vitro culture and identified their endothelial origin, as well as observed growth features of HEECs from the two different origins. Finally we identified the difference in gene expression profile when combined suppression subtractive hybridization(SSH) with genechip and confirmed the results by quantitative reverse transcription polymerase chain reaction (qRT-PCR). The HEECs derived from endometriosis exhibited potent survival ability in vitro compared to that from non-endometriosis. We found that gremlin and fibronectin genes were up-regulated in HEECs derived from eutopic endometrium of patients with endometriosis when compared with that from patients without endometriosis. Our study implies that enhanced angiogenic capacity of eutopic HEECs may be an independent determinant in endometriotic aberrant angiogenesis in addition to the interaction of exfoliated endometrium and peritoneal environment elements such as activated macrophages and soluble cytokines. Experiment Overall Design: We analyzed 5 arrays for HEECs derived from eutopic endometrium of patients with endometriosis and 5 arrays for HEECs derived from that of patients without endometriosis

Project description:This project aims at comparing endometrium from women with and without endometriosis during the secretory phase of menstrual cycle. The present results constitute a first step towards identifying potential diagnosis biomarkers and may provide a better understanding of endometriosis especially the etiology of the disease.

Project description:Purpose- To identify the pathways and processes that are dysregulated in the eutopic endometrium of women with endometriosis Methods-RNA sequencing was used to detect and quantify the transcripts encoded by the whole genome in the eutopic endometrium. Mid-secretory phase eutopic endometrial samples from women with (n=4) and without endometriosis (n=4) were processed for RNA sequencing and the data were compared to identify the transcripts displaying differential abundance in women with endometriosis, compared to those without endometriosis (controls)

Project description:Introduction: Endometriosis is a debilitating condition where endometrial-like tissue grows outside the uterus and rarely in distant sites such as the lungs, heart and brain. Symptoms are severe chronic pain, bladder/bowel problems, painful sex and infertility. Differences in endometrium between women with and without endometriosis have not been constructive, and there is still paucity in its pathogenesis and non-invasive diagnostic test, leading to delayed diagnosis (~10 years) and effective treatment. Menstrual fluid (MF) gives a peak into endometrial health. Could MF extracellular vesicles (EVs) point to the pathogenesis and a non-invasive diagnostic tool for endometriosis? Aims: To identify differences in protein-cargo in MF-EVs from women with and without endometriosis, define their functional contribution to mesothelial niche cells for lesion establishment and determine whether MF-sEV can be a non-invasive endometriosis diagnostic tool. Methods: MF was collected from women with and without endometriosis on day 2 of menses and EVs isolated using differential centrifugation. MF-EVs were identified by size, morphology and protein markers and subjected to TMT- quantitative proteomics assay. Differentially expressed proteins were analysed. Ctrl and Endo MF-sEV were co-cultured with mesothelial cells to assess for uptake and changes in the adhesive and junctional proteins. Results: Spherical-shaped MF-EVs were identified with mean diameters of 121.9 nm (Endo) and 123.8 nm (Ctrl), expressing TSG101, Alix and Syntenin-1 sEV proteins. MF-sEV proteins originated from endometrial cells: stem cells, leucocytes, and endothelial and smooth muscle cells, validating the endometrial origin of the MF-EVs. 77% of identified proteins were differentially expressed. In endo-MF-sEV, proteins regulating HGF receptor (anoikis), cellular senescence and multiple apoptotic, nitrogen compound metabolic processes and TRP channels signalling (immunity and contraction regulation) were decreased, potentially promoting lesion establishment, survival and pain. Similarly, antibacterial peptides (cathelicidin, mucin-1, lipocalin2 and serum amyloid A) were downregulated. The majority of proteins were significantly downregulated in endometriosis suggesting a dysregulation in the protein synthesis and cellular communication for homeostasis. Two-thirds of upregulated proteins were immunoglobulins indicating inflammatory pathogenesis. This was reflected by an increased Endo-MF-EVs uptake by mesothelial cells, with decreased scribble resulting in decreased cellular resistance and permeability. Conclusions: MF-EVs contain vital information indicative of endometriosis pathogenesis and may be the key to developing a simple and early diagnostic tool.
