Project description:Peritoneal carcinomatosis is a frequent finding in patients with primary gastric cancer, and it is associated with a poor prognosis. A major mechanism in peritoneal carcinomatosis is the dissemination of cancer cells into the abdominal cavity, mainly in diffuse gastric adenocarcinoma. The features that enable diffuse primary gastric tumours to develop peritoneal dissemination have been little investigated and are only incompletely understood. We therefore compared the gene expression profile in patients with diffuse primary gastric cancer with and without peritoneal carcinomatosis. Specimens from consecutive gastric cancer patients with and without peritoneal carcinomatosis were investigated using oligonucleotide microarrays. Keywords: Disease state analysis

Project description:Characterizations of ascites proteome from ovarian peritoneal carcinomatosis (PC) and gastric PC have demonstrated that ascites contains elevated pro-tumorigenic factors. Reasoning that the composition of ascitic fluid might offer insight into the memory of key biological events occurring intra-abdominally, we hypothesized that paracrine factors essential for survival and growth of peritoneal deposits are secreted into and circulate within ascitic fluid. Our data from cytokine array profile suggest that ascites contains biologically active ligands capable of supporting cellular functions of cancer cells. To decipher downstream signalling pathways activated in cancer cells when exposed to ascites, we performed gene expression analysis of Colo-205 cells upon exposure to PC ascites and ligand inhibitor.

Project description:Interleukin-33 (IL-33) is a novel member of the IL-1 family of cytokines that plays diverse roles in the regulation of immune responses. IL-33 exerts its effects by binding to a heterodimeric receptor complex consisting of interleukin-1 receptor like 1 (IL1RL1) and an accessory receptor protein IL-1RAcP resulting in the production and release of proinflammatory cytokines. A detailed understanding of the signaling pathways activated by IL-33 remains elusive. To elucidate IL-33 mediated signaling, we performed a global quantitative phosphoproteomic analysis using stable isotope labeling by amino acids in cell culture. Employing anti-phosphotyrosine antibodies and titanium dioxide-based enrichment strategies, we identified 6,207 phosphorylation sites mapping to 2,013 phosphoproteins of which more than 185 phosphosites are regulated by IL-33 stimulation. Our findings will greatly expand the understanding of IL-33 signaling and provide novel therapeutic targets for IL-33/IL-33R-associated diseases in humans.

Project description:IL-2 and IL-21 are closely related cytokines that might have arisen by gene duplication. Both cytokines promote the function of effector CD8+ T cells, but their distinct effects on antigen-driven differentiation of naïve CD8+ T cells into effector CD8+ T cells are not clearly understood. We found that antigen-induced expression of eomesodermin and maturation of naïve CD8+ T cells into granzyme B and CD44 expressing effector CD8+ T cells was enhanced by IL-2, but, unexpectedly, suppressed by IL-21. Furthermore, IL-21 repressed expression of IL-2Ra and inhibited IL-2-mediated acquisition of a cytolytic CD8+ T cell phenotype. Despite its inhibitory effects, IL-21 did not induce anergy, but instead potently enhanced the capacity of cells to mediate tumor regression upon adoptive transfer. In contrast, IL-2, surprisingly, impaired the subsequent anti-tumor function of transferred cells. Gene expression studies revealed a distinct IL-21-program that was characterized phenotypically by increased expression of L-selectin and functionally by enhanced anti-tumor immunity that was not reversed by secondary in vitro stimulation with antigen and IL-2. Thus, the efficacy of CD8+ T cells for adoptive immunotherapy can be influenced by opposing differentiation programs conferred by IL-2 and IL-21, a finding with important implications for the development of cellular cancer therapies.

Project description:Biologics that target IL-4Ra or IL-33 pathways have demonstrated clinical efficacy in asthma and chronic obstructive pulmonary disease (COPD), highlighting the importance of IL-4, IL-13 and IL-33 in respiratory diseases. Despite this, there are limited studies that link preclinical models to human disease and evaluate disease biology in the setting of clinical trials. To address these gaps, we evaluated transcriptional, cellular and pathophysiological processes driven by IL-4/ IL-13 and IL-33 using human innate cells in vitro, a mouse model of airway inflammation and a Bronchial Allergen Challenge (BAC) in house dust mite (HDM)-sensitized individuals with mild asthma. Using the HDM mouse model of airway inflammation, we show that blockade of either IL-4Ra or IL-33 at the peak of type 2 (T2) inflammation leads to inhibition of airway inflammation and remodeling. While the combination of dupilumab and itepekimab was not additive, blockade of both IL-33 and IL-4Ra in a severe, late-phase mixed T1/T2 inflammation reduced all measured parameters. Consistent with some of these observations in mice, blocking either IL-33 or IL-4Ra in the context of T2 airway inflammation suppressed sputum gene expression in individuals with mild persistent asthma post-BAC. Overall, these results highlight that IL-33 and IL-4/IL-13 are key drivers of airway inflammation and remodeling and provide insight into the differences in targeting IL-4Ra or IL-33 pathways in asthma independently or in combination.

Project description:Peritoneal carcinomatosis (PC) originating from colorectal cancer (CRC) is associated with a poor prognosis and rapid disease progression. Metastasis is the major cause of death in patients with CRC whereas primary locoregionally circumscribed tumors are mostly curable. Due to the lack of appropriate and realistic mouse models for metastasis of CRC until recently, the research about metastasis of these tumors and possible therapeutic options is still in its infancy. With the establishment of murine CRC tumor organoids, mouse models were established which realistically mimic the process of tumor cell metastasis to the liver and the lung. However, to date no appropriate model for PC is described. Here, we establish a realistic model for peritoneal metastasis of colorectal cancer upon surgical transplantation of tumor organoids into the cecum wall. This mouse model for PC recapitulates human PC which makes it an ideal model for research of the biology of metastasis of colorectal cancer to the peritoneal cavity and for its usage for preclinical drug screening as well as for the evaluation of new therapeutic approaches which are highly needed in clinical reality.

Project description:IL-33 is an inflammatory cytokine contributing to asthma, Chronic Obstructive Pulmonary Disease (COPD), and autoimmune diseases. Although recent studies suggest that IL-33 can induce the generation of autoantibodies, the role of IL-33 on B cell maturation and tolerance is poorly understood. Here, by inducing systemic overexpression of IL-33 in mice, we show that this cytokine induces the IL-5 and CD4 T cell-dependent accumulation of plasmablasts and plasma cells of all isotypes in the spleen, and leads to an increased antibody production. IL-33 also disrupts splenic architecture and elevates autoantibody production, indicating a break in peripheral tolerance. Consistently, elevated levels of IL-33 exacerbate autoantibody production, kidney damage, and decrease survival in a mouse model of lupus. Additionally, intranasal delivery of IL-33 in mice exposed to house dust mite extract (HDM) increases autoantibodies in the lung. Notably, blocking IL-33 reduced the autoantibodies generated during HDM exposure, indicating that HDM-induced autoantibody production is IL-33 dependent. Thus, our findings implicate IL-33 in the break of peripheral B cell tolerance, opening new therapeutic avenues for the treatment of infection, COPD and autoimmune conditions.

Project description:IL-33 is a nuclear cytokine from the IL-1 family that plays important roles in health and disease. Under healthy conditions, IL-33 is constitutively expressed to high levels in the nucleus of producing cells in various human and mouse tissues. The extracellular function of IL-33 cytokine has been well documented, but it remains unclear whether intracellular nuclear IL-33 has additional functions in the nucleus. Here, we used a global proteomic approach based on quantification of 5000 individual proteins by high-resolution mass spectrometry to compare the extracellular and intracellular roles of IL-33 in primary human endothelial cells, a major source of IL-33 protein in human tissues. Large-scale analysis of protein expression was performed either after stimulation of the cells with the IL-33 mature form IL-3395-270 (during 6h or 24h) or after siRNA knockdown of intracellular IL-33 (two experiments, each with a different pool of distinct siRNAs, noted siRNA1 and siRNA2). In each case, proteins were fractionated by 1D SDS-PAGE in 12 gel bands, and label-free quantitative analysis was performed. The present dataset contains the files for the two experiments of knockdown of endogenous nuclear IL-33 expression: - RNA silencing strategy 1. Knockdown of endogenous nuclear IL-33 expression was performed with a pool of four distinct siRNAs (Dharmacon ON-TARGETplus SMARTpool IL-33 siRNAs) that have been specifically modified for efficient silencing of the target gene with reduced off-target effects. Cells transfected with these siRNA duplexes (si1) were compared with those transfected with the provided controls (CTsi1). Three independent biological replicates (noted _A, _B, _C) were prepared and analyzed for each condition, leading to 6 different samples. Each of them was fractionated into 12 gel bands analyzed by nanoLC-MS/MS, leading to 72 raw files. - RNA silencing strategy 2. The second knockdown strategy was based on the use of an independent pool of three siRNAs targeting IL-33, predesigned by another provider using new and critical siRNA design rules (Sigma MISSION Predesigned Il-33 siRNAs based on Rosetta siRNA design algorithm). Cells transfected with these siRNA duplexes (si2) were compared with those transfected with the provided controls (CTsi2). Three independent biological replicates (noted _A, _B, _C) were prepared and analyzed for each condition, leading to 6 different samples. Each of them was fractionated into 12 gel bands analyzed by nanoLC-MS/MS, leading to 72 raw files.
