The interleukin 22–oncostatin M axis promotes intestinal inflammation and tumorigenesis

ABSTRACT: Multicellular cytokine networks orchestrate the onset and progression of intestinal inflammation and colitis-associated cancer (CAC). Interleukin 22 (IL-22), a member of the IL-10 superfamily, is known for promoting epithelial cell recovery but can inadvertently fuel inflammation and tumorigenesis. Here, we demonstrate that IL-22, derived from group 3 innate lymphoid cells (ILC3), triggers oncostatin M (OSM) responsiveness in intestinal epithelial cells by activating STAT3 and upregulating OSM receptor (OSMR) expression. OSM, a member of the IL-6 cytokine family implicated in inflammatory bowel disease, collaborates with IL-22 to sustain STAT3 activation, promoting proinflammatory adaptations and immune cell chemotaxis to the intestine. Conditional deletion of OSMR in epithelial cells protects mice from colitis and CAC. Additionally, pharmacological blockade of OSM reduces the progression of established CAC. Our study reveals a novel mechanism by which OSM sustains intestinal inflammation and CAC, identifying the IL-22-OSM axis as a promising therapeutic target.

The interleukin 22–oncostatin M axis promotes intestinal inflammation and tumorigenesis [Epithelial_cells_BulkRNA-seq]

Project description:Multicellular cytokine networks regulate the onset of intestinal inflammation and colitis-associated cancer (CAC). Interleukin 22 (IL-22) promotes epithelial cell recovery but can also drive inflammation and tumorigenesis. We demonstrate that IL-22 from innate lymphoid cells activates STAT3 and increases OSM receptor expression in intestinal epithelial cells. This activation leads to sustained STAT3 activity via OSM, promoting inflammation and tumorigenesis. Deleting the OSM receptor or blocking OSM pharmacologically mitigates colitis and CAC. Our findings highlight the IL-22-OSM axis as a potential therapeutic target for these conditions.

Expression data from colon epithelium of STAT3IEC-KO in acute DSS colitis

Project description:STAT3 is a pleiotropic transcription factor with important functions in cytokine signalling in a variety of tissues. However, the role of STAT3 in the intestinal epithelium is not well understood. Here we demonstrate that development of colonic inflammation is associated with the induction of STAT3 activity in intestinal epithelial cells (IEC). Studies in genetically engineered mice showed that epithelial STAT3 activation in DSS colitis is dependent on IL-22 rather than IL-6. IL-22 was secreted by colonic CD11c+ cells in response to Toll-like receptor stimulation. Conditional knockout mice with an IEC specific deletion of STAT3 activity were highly susceptible to experimental colitis, indicating that epithelial STAT3 regulates gut homeostasis. STAT3IEC-KO mice, upon induction of colitis, showed a striking defect of epithelial restitution. Gene chip analysis indicated that STAT3 regulates the cellular stress response, apoptosis and pathways associated with wound healing in IEC. Consistently, both IL-22 and epithelial STAT3 were found to be important in wound-healing experiments in vivo. In summary, our data suggest that intestinal epithelial STAT3 activation regulates immune homeostasis in the gut by promoting IL-22-dependent mucosal wound healing. 4 samples of colon epithelium were analyzed from 4 mice (2 per group Stat3flfl VillinCre- and Stat3flfl VillinCre+, respectively) after they had been treated with DSS (2.5%) for 5 days

IL-22 Prevents Epithelial Dysfunction During Citrobacter rodentium-induced Infectious Colitis

Project description:IBD is a complex autoimmune disease characterized by dysregulated interactions between host immune responses and microbiome at the intestinal epithelium interface. Here we identified shared protein alterations in intestinal epithelial differentiation and function between IBD and Citrobacter rodentium infected FVB mice. We discovered that prophylactic treatment with the mucosal healing therapy IL-22.Fc in the infected FVB mice reduced disease severity and rescued the mice from lethality. Notably, we observed an emergence of intermediate undifferentiated intestinal epithelial cells upon infection, with disrupted expression of the solute transporter machinery as well as components critical for intestinal barrier integrity. Multi-omics analyses revealed that with IL-22.Fc treatment several disease associated changes were prevented (including disruption of the solute transporter machinery), and proper physiological homeostatic functions of the intestine was restored. Taken together, we unveiled the disease relevance of the C. rodentium induced colitis model to IBD and demonstrated the protective role of the mucosal healing therapy IL-22.Fc in ameliorating the epithelial dysfunction.

Heterocellular OSM-OSMR signalling drives pancreatic tumour growth and metastasis through functional fibroblast reprogramming

Project description:Pancreatic ductal adenocarcinoma (PDA) is a lethal malignancy characterised by a pathologicalfibroinflammatorymicroenvironment. Dichotomous tumour-promoting and -restrictive roles have been ascribed to the tumour microenvironment, however thedisparate effect of individual stromal subsets remains incompletely characterised. Here, we describe how heterocellular OSM-OSMR signalling instructsfibroblast reprogramming,tumourgrowth and metastasis.Macrophage-secreted OSM stimulatesinflammatory gene expression in cancer-associated fibroblasts (CAFs), which in turn induce a pro-tumorigenic environment and engage tumour cellsurvival and migratory signalling pathways. Tumour cells implanted in Osm-deficient (Osm-/-) mice display an epithelial-dominated morphology, reduced tumour growth and did notmetastasise. Moreover, the tumour microenvironment of Osm-/-animals exhibit increased abundance of αSMAposmyofibroblasts and a shift in myeloid and T cell phenotypes, consistent with a more immunogenic environment. Taken together, these data demonstrate how OSM-OSMR signalling coordinates heterocellular interactions to drive a pro-tumorigenic environment in PDA.

Interleukin-22 (IL-22) regulates B3GNT7 expression to induce intestinal fucosylation of O-linked glycans

Project description:Interleukin (IL) - 22 is a cytokine that plays a critical role in the maintenance of intestinal epithelial homeostasis. Its downstream functions are mediated through ligation of its heterodimeric receptor comprised of IL-22 receptor subunit alpha 1 (IL-22Ra1) and IL-10R2, and subsequent activation of signal transducer and activator of transcription 3 (STAT3). IL-22 signaling can induce genes necessary for intestinal epithelial cell proliferation, tissue regeneration, tight junction fortification, and production of antimicrobials. Emerging studies have also implicated IL-22 signaling in the regulation of intestinal epithelial fucosylation in mice. However, whether IL-22 regulates intestinal fucosylation in human intestinal epithelial cells and the molecular mechanisms that govern this process are unknown. Here, we show that IL-22 signaling regulates expression of the B3GNT7 transcript, which encodes a β1-3-N-acetylglucosaminyltransferase that can participate in the synthesis of poly-N-acetyllactosamine (LacNAc) chains. Additionally, we show that IL-22 signaling regulates levels of the a1-3-fucosylated Lewis X (Lex) blood group antigen and this glycan epitope is primarily displayed on heavily O-glycosylated intestinal epithelial glycoproteins. The IL-22-mediated increase in Lex antigen levels requires B3GNT7, as disruption of B3GNT7 expression moderated the IL-22-dependent increase in Lex antigen levels. Moreover, we show that increased expression of B3GNT7 alone is sufficient to promote increased display of Lex-decorated carbohydrate glycan structures primarily on O-glycosylated intestinal epithelial glycoproteins. Together, the data presented here identify B3GNT7 as a critical intermediary in IL-22-dependent induction of intestinal fucosylation of O-linked glycans and uncover a novel role for B3GNT7 in intestinal glycosylation.

Diverse Targets of the Transcription Factor STAT3 Contribute to T Cell Pathogenicity and Homeostasis [Affymetrix Expression]

Project description:STAT3, an essential transcription factor with pleiotropic functions, plays critical roles in the pathogenesis of autoimmunity. Despite recent data linking STAT3 with inflammatory bowel disease, exactly how it contributes to chronic intestinal inflammation is not known. Using a T cell transfer model of colitis we found that STAT3 expression in T cells was essential for the induction of both colitis and systemic inflammation. STAT3 was critical in modulating the balance of T helper 17 (Th17) and regulatory T (Treg) cells, as well as in promoting CD4+ T cell proliferation. We used chromatin immunoprecipitation and massive parallel sequencing (ChIP-Seq) to define the genome-wide targets of STAT3 in CD4+ T cells. We found that STAT3 bound to multiple genes involved in Th17 cell differentiation, cell activation, proliferation and survival, regulating both expression and epigenetic modifications. Thus, STAT3 orchestrates multiple critical aspects of T cell function in inflammation and homeostasis. WT and STAT3-deficient CD4+ T cells were activated with anti-CD3 and anti-CD28, in the presence of cytokines (interleukin (IL)-6 and TGFb) or medium alone for three days. RNA was extracted and hybridized to Affymetrix microarray chips.

Effects of murine Oncostatin M on OP9 stromal cells and NIH/3T3 fibroblasts

Project description:The IL-6 cytokine Oncostatin M (OSM) is involved in cell development, growth, hematopoiesis, inflammation and cancer. Intriguingly, OSM has proliferative and antiproliferative effects de-pending on the target cell. The molecular mechanisms underlying these opposing effects are not fully understood and its role in tumorigenesis remains controversial. In the present study, we investigated the effect of murine OSM (mOSM) on proliferation in two cell types of distinct origin. We found that mOSM impairs the proliferation of murine bone marrow (BM) stromal cell lines and primary BM stromal cells, whereas murine fibroblasts responded to mOSM with increased proliferation. When we set out to reveal the mechanisms underlying these opposing effects of OSM on proliferation, we detected increased expression of the OSM receptors OSMR and LIFR in stromal cells. Interestingly, Osmr knockdown and Lifr overexpression attenuated the OSM-mediated effect on proliferation in both cell lines indicating that mOSM affected the pro-liferation of both cell lines signaling mainly through the OSMR. Furthermore, mOSM induced activation of the JAK-STAT, PI3K-AKT and MAPK-ERK pathways in OP9 and NIH/3T3 cells with differences in total protein levels between the two cell lines. Our findings offer new insights into the regulation of proliferation by mOSM.
