Project description:Aberrant STAT3 activation is a major contributor to endometriosis. We used microarrays to detail the mechanism underlying Stat3 loss.

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.

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:Many esophageal diseases arise in the context of chronic inflammation, but the role that esophageal epithelial cells play in initiating inflammation remains poorly understood. Since the IKKβ/NF-κB and STAT3 pathways are critical signaling hubs that drive inflammatory-mediated responses, we aimed to identify how these two pathways regulate gene expression in esophageal epithelial cells. In this study, we performed RNA-Seq analysis on esophageal epithelium from mice with overexpression of constitutively active Ikkb and/or loss of Stat3 specifically in esophageal epithelial cells.

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:Endometriosis is a common, chronic inflammatory condition that frequently results in pain and infertility and is estimated to affect 6–10% of women of reproductive age. However, the mechanisms underlying the induction of inflammation in endometriosis remain unclear. Here, we identified that ectopic endometrial T-cell-derived active interleukin (IL)-16 acts as an inflammation-driving cytokine in endometriosis. Furthermore, we found that in ectopic endometrial T cells, the activation of IL-16 requires iron overload-induced caspase-3 activity and that the release of active IL-16 is reliant on GSDME-mediated pyroptosis. These observations suggest that active IL-16 may represent a promising target in the treatment of endometriosis.
