Characterization of an Osmr Conditional Knockout Mouse Model

ABSTRACT: Oncostatin M (OSM) is a member of the interleukin-6 (IL-6) family of cytokines and has been found to have anti-inflammatory and pro-inflammatory properties in various cellular and disease contexts. OSM signals through two receptor complexes, one of which includes OSMRb. Here, we investigated OSM-OSMRb signaling in adult mouse hematopoietic stem cells (HSCs) using the conditional Osmrfl/fl mouse model B6;129-Osmrtm1.1Nat/J. We crossed Osmrfl/fl mice to interferon-inducible Mx1-Cre, which is robustly induced in adult HSCs. From these mice, we isolated HSCs by flow cytometry, stimulated with or without recombinant OSM for 1 hour, and assessed gene expression changes in control versus Osmr knockout HSCs by RNA-seq. This data may be utilized to investigate OSMRb-dependent and -independent OSM signaling as well as the transcriptional effects of an IL-6 family cytokine on mouse HSCs to further define its anti-inflammatory versus pro-inflammatory properties.

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

Project description:Pancreatic ductal adenocarcinoma (PDA) is a lethal malignancy characterised by a pathological fibroinflammatory microenvironment. Dichotomous tumour-promoting and -restrictive roles have been ascribed to the tumour microenvironment, however the effects of individual stromal subsets remains incompletely characterised. Here, we describe how heterocellular OSM-OSMR signalling instructs fibroblast reprogramming, tumour growth and metastasis. Macrophage-secreted OSM stimulates inflammatory gene expression in cancer-associated fibroblasts (CAFs), which in turn induce a pro-tumorigenic environment and engage tumour cell survival and migratory signalling pathways. Tumour cells implanted in Osm-deficient (Osm-/-) mice display an epithelial-dominated morphology, reduced tumour growth and did not metastasise. Moreover, the tumour microenvironment of Osm-/- animals exhibit increased abundance of αSMApos myofibroblasts 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.

Gene-expression analysis of Oncostatin-M (OSM) signalling in cervical squamous cell carcinomas over-expressing the Oncostatin-M receptor (OSMR)

Project description:The type II Oncostatin M receptor (OSMR) serves as the main binding site for the pleiotropic cytokine OSM. We have previously demonstrated a positive correlation between copy number driven OSMR over-expression and adverse clinical outcome in cervical tumours and have also established enhanced angiogenic, migratory and invasive potential as major consequences of OSMR over-expression using cell-line models of cervical cancer. By analysis of gene expression patterns in cell lines and tumours, this study now systematically defines cohorts of genes that are implicated for the phenotypes observed. Importantly, we have identified 15 OSM induced genes that are involved in at least one of these key functions and are up-regulated in both OSMR over-expressing cell-lines and tumours. These genes can serve as markers of OSM signalling in OSMR over-expressing SCCs and represent suitable targets for functional characterisation. Gene expression of 4 cervical SCC cell lines analysed (2 with and 2 without OSMR overexpression) at 6 different time-points, with 3 replicates at each time-point.

Oncostatin M is a Master Regulator of an Inflammatory Network in Dnmt3a-Mutant Hematopoietic Stem Cells

Project description:Age-associated clonal hematopoiesis (CH) occurs due to somatic mutations accrued in hematopoietic stem cells (HSCs) that confer a selective advantage in the context of aging. The mechanisms by which CH-mutant HSCs gain this advantage with aging are not comprehensively understood. Using unbiased transcriptomic approaches, we identify Oncostatin M (OSM) signaling as a candidate contributor to aging-driven Dnmt3a-mutant CH. We find that Dnmt3a-mutant HSCs from young mice do not functionally respond to acute OSM stimulation with respect to proliferation, apoptosis, hematopoietic engraftment, or myeloid differentiation. However, young Dnmt3a-mutant HSCs transcriptionally upregulate an inflammatory cytokine network in response to acute OSM including genes encoding IL-6, IL-1b and TNFa. In addition, OSM-stimulated Dnmt3a-mutant HSCs upregulate the anti-inflammatory genes Socs3 and Nr4a1, creating a negative feedback loop limiting sustained activation of the inflammatory network. In the context of an aged BM microenvironment with chronically elevated levels of OSM, Dnmt3a-mutant HSCs upregulate pro-inflammatory genes but do not upregulate Socs3 and Nr4a1. Together, our work suggests that chronic inflammation with aging exhausts the regulatory mechanisms in young CH-mutant HSCs that resolve inflammatory states, and that OSM is a master regulator of an inflammatory network that contributes to age-associated CH.

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.

Oncostatin M (OSM) and Leukemia Inhibitory factor (LIF) treatment of osteoblasts via LIF and OSM receptors

Project description:Oncostatin M (OSM) and Leukemia Inhibitory Factor (LIF) signal within cells via the gp130 (Il6st) coreceptor bound either to the LIF receptor (LIFR) or the oncostatin M receptor (OSMR), but whether murine OSM can act through both receptors is controversial. Both LIF and OSM stimulate bone formation, inhibit adipocyte differentiation, and promote osteoclast differentiation, but our earlier work suggested this may depend on the receptor subtype used. This project aimed to identify those gene targets regulated by murine OSM via OSMR and LIFR by using wild type and OSMR null primary osteoblasts. Cells were differentiated to their most mature state (i.e. osteocytes) because the only prior target gene known to be regulated by murine OSM via the LIFR was an osteocyte-specific gene, sclerostin.
