Project description:We performed gene expression analysis human peritoneal endometriosis lesions, eutopic endometrium from endometriosis patients and peritoneum form endometriosis patients.The goal of the study was to analyse gene expression differences between peritoneal endometriosis lesion and eutopic endometrium and peritoneal endometriosis lesion and peritoneum.

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:Gp130 receptor engagement on neoplastic cells provides a link by which an inflammatory microenvironment facilitates tumour promotion. Although hyperactivation of the gp130-dependent Stat3 signalling node is commonly observed in solid tumours, Stat3 remains a challenging therapeutic target. To mimic excessive Stat3 signalling, we molecularly validate the gp130FF mouse as a preclinical model for inflammation-associated intestinal-type gastric cancer (IGC), with aberrant mammalian target of rapamycin (mTOR) pathway activity as shared feature. Accordingly, administration of the mTorc1 inhibitor RAD001 reversibly reduced IGC burden in gp130FF mice and suppressed colitis-associated cancer in wild-type mice. Since the therapeutic effect of RAD001 occurs independently of Stat3 hyperactivation, which is also dispensable for gp130-dependent engagement of the PI3K/Akt/mTorc1 pathway, we conclude that mTorc1 signalling limits tumour promoting Stat3 activity The mouse whole-genome gene expression profiling was performed on Illumina's MouseWG-6 v2.0 Expression BeadChips for 24 mice, with 8 mice in each group (gp130WT antral tissue, gp130FF unaffected antral tissue and gp130FF tumour tissue).

Project description:The etiology and pathophysiology of endometriosis remain unclear. Accumulating evidence suggests that aberrant microRNA (miRNA) expression may be involved in the pathogenesis and development of endometriosis. This study therefore aims to survey key miRNAs and further understand the mechanism of endometriosis. Paired expression profiling of miRNA in ectopic endometria compared with eutopic endometria were determined by high-throughput sequencing techniques in eight patients with ovarian endometriosis. Our study presents a unique insight into the regulatory network of this enigmatic disorder and possibly provides clues regarding replacement therapy of endometriosis.

Project description:The etiology and pathophysiology of endometriosis remain unclear. Accumulating evidence suggests that aberrant mRNA and lncRNA expressions may be involved in the pathogenesis and development of endometriosis. This study therefore aims to survey key TFs, genes and lncRNAs and further understand the mechanism of endometriosis. Paired expression profiling of mRNA and lncRNA in ectopic endometria compared with eutopic endometria were determined by high-throughput sequencing techniques in eight patients with ovarian endometriosis. Our study presents a unique insight into the regulatory network of this enigmatic disorder and possibly provides clues regarding replacement therapy of 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:Mechanisms of immune dysregulation against established tumors are relatively well understood. Much less is known about the role of immune effectors against cancer precursor lesions. Endometrioid and clear cell ovarian tumors may partly derive from endometriosis, a commonly diagnosed chronic inflammatory disease. We performed here the most comprehensive immune gene expression analysis of pelvic inflammation in endometriosis and endometriosis-associated ovarian cancer (EAOC). RNA was extracted from 120 paraffin tissue blocks comprising of normal endometrium (n=32), benign endometriosis (n=30), atypical endometriosis (n=15) and EAOC (n=43). Serous tumors (n=15) were included as non-endometriosis associated controls. The immune microenvironment was profiled using Nanostring and the nCounter® GX Human Immunology Kit, comprising probes for a total of 511 immune genes. Please note that 3 normal endometrium samples did not pass the array quality filtering and therefore excluded in the data analyses.
