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

ABSTRACT: 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.

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

Project description: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.

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

Oncostatin M neutralization in E. coli pneumonia

Project description:Oncostatin M (OSM) is an IL-6 family cytokine that is necessary for neutrophil recruitment in pneumonia by inducing STAT3-dependent production of CXCL5. We used microarrays to identify additional pathways affected by OSM neutralization in the lungs during pneumonia.

The MicroRNAmiR-223constrains Colitis-associated tumorigenesis by limiting myeloid cell infiltration and Chemokine expression

Project description:Aberrant intestinal inflammation plays a critical role in the development of colitis-associated colorectal cancer (CAC), yet the mechanisms behind this progression are not clearly defined. While altered microRNA (miRNA) expression is observed in CAC, it is unclear how myeloid-specific microRNA’s impact on the inflammatory process that underpins the continuum from Ulcerative colitis (UC) to tumorigenesis. Here we used the Azoxymethane-Dextran Sodium Sulfate (AOM-DSS) (10mg/kg) model of CAC on miR-223-/y and WT mice, with an overall aim of identifying differences in their expression profiles following AOM/DSS treatment.

Gene expression of HCT116 cells after stimulation with oncostatin M (OSM)

Project description:To evaluate gene expression profiles in intestinal epithelial cells (IEC) after OSM stimulation, we have employed whole genome microarray expression profiling as a discovery platform to identify relevant genes which are potentially of interest to reveal the role of OSM in intestinal inflammation. The most strongly up-regulated genes were SERPINS, which belong to the family of serin peptidase inhibitors with antiprotease activities, most of them serine and cysteine proteases. SERPINB4, SERPINB3 and SERPINA3 were the genes with the strongest up-regulation, also verified in qPCR. OSM-induced SERPIN up-regulation may contribute to anti-apoptotic and proliferative effects of OSM in IEC. HCT116 cells were starved overnight with medium containing 1% FCS after reaching 70% confluency. On the next day, cells were stimulated in quadruplicates with 100 ng/mL OSM or left unstimulated. RNA was isolated 6 hours after stimulation and RNA concentration and purity was measured.

Oncostatin M signaling drives cancer-associated skeletal muscle wasting

Project description:Investigating muscle wasting in a murine model of cancer cachexia, we identified Oncostatin M (OSM) as a potential mediator of inflammatory responses in skeletal muscle. OSM is a member of the IL-6 family of cytokines and has crucial functions in cell growth, differentiation, and inflammation. Our results demonstrate that OSM induces muscle atrophy. To understand if its effect is specific or it is a general effect of IL6 family cytokines, primary myotubes were treated with OSM, IL6 and LIF for 48hrs. Our findings showed that OSM potently induces muscle wasting in differentiated myotubes.
