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.

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.

Macrophages control pathological interferon responses during viral respiratory infection

Project description:Antiviral immune mediators, including interferons and their downstream effectors, are critical for host defense yet can become detrimental when uncontrolled. Here, we identify a macrophage-mediated anti-inflammatory mechanism that limits type I interferon (IFN-I) responses. Specifically, we found that cellular stress and pathogen recognition induce Oncostatin M (OSM) production by macrophages. OSM-deficient mice succumbed to challenge with influenza or a viral mimic due to heightened IFN-I activation. Macrophage-derived OSM restricted excessive IFN-I production by lung epithelial cells following viral stimulation. Furthermore, reconstitution of OSM in the respiratory tract was sufficient to protect mice lacking macrophage-derived OSM against morbidity, indicating the importance of local OSM production. This work reveals a host strategy to dampen inflammation in the lung through the negative regulation of IFN-I by macrophages.
