Genome-wide analysis of interleukin (IL) -6 and IL-11 responsive genes in murine gastric tumors

ABSTRACT: We performed micrarrays to analyse gene expression in spontaneously arising gastric tumors from gp130Y757F/F mutant mice (Tebbutt et al., 2002) following administration of recombinant human IL-6 or IL-11. The present study was designed to assess differences in gene expression in response to IL-6 and IL-11, two cytokines which both activate the shared gp130 receptor and downstream Stat3 signalling pathway. Since gastric tumorigenesis in gp130Y757F/F mice is strictly dependent on IL-11, but not IL-6 signalling (Ernst et al., 2008) the study aimed to identify IL-6 and IL-11 specific target genes which may account for the IL-11 dependent tumor development. Total RNA was obtained from gastric tumor tissue of gp130Y575F/F mice collected 60 min after a single systemic (i.p.) administration of PBS (vehicle control), recombinant human IL6 or IL11 (5 ug). The gene expression profile of the IL-6 and IL-11 treated samples were separately compared to the PBS (vehicle) treated control samples, resulting in two lists of responsive genes (”IL-6 vs control” and “IL-11 vs control”).

Macrophages reprogramming improves immunotherapy of IL-33 in peritoneal metastasis of gastric cancer

Project description:Peritoneal metastasis (PM) has a suppressive tumor immune microenvironment (TIME), which limits the effects of immunotherapy. This study aims to investigate the immunomodulatory effects of intraperitoneal administration of IL-33 on PM-associated TIME. Immunocompetent mice were used to investigate the role of IL-33 in development of abdominal dissemination and host outcome. Murine (m) and human (h) gastric cancer cells were tested for their response to IL-33 by qRT-PCR, flow cytometry, and immunofluorescence. Survival was significantly prolonged in patients with high Il-33 mRNA expression. Intraperitoneal administration of IL-33 could induce the celiac inflammatory environment, activate immunologic effector cells and reverse the immunosuppressive tumor microenvironment, which delayed tumor progression and peritoneal metastasis of gastric cancer. Mechanistically, IL-33 could induce M2 polarization by activating p38-GATA-binding protein 3 (GATA3) signaling pathway. IL-33 combined with anti-CSF1R or p38 inhibitor to regulate tumor-associated macrophages (TAMs) showed synergistic anti-tumor effect. Intraperitoneal administration of IL-33 inducing local inflammatory milieu provided a novel approach for the treatment of metastatic peritoneal malignancies, which combined with TAMs reprogramming to reshape TIME could achieve better treatment efficacy.

IL-11 is a therapeutic target in idiopathic pulmonary fibrosis

Project description:Idiopathic pulmonary fibrosis (IPF) is a fatal lung disease where invasive pulmonary myofibroblasts secrete collagen and destroy lung integrity. Here we show that IL-11 is upregulated in the lung of IPF patients, associated with disease severity and is secreted from IPF fibroblasts. In vitro, IL-11 stimulates lung fibroblasts to become invasive, ACTA2+ve, collagen secreting myofibroblasts, in an ERK-dependent fashion. In mice, fibroblast-specific transgenic expression or administration of Il-11 drives lung fibroblast-to-myofibroblast transformation and causes lung fibrosis. Il11ra1 deleted mice, whose lung fibroblasts are unresponsive to pro-fibrotic stimulation, are protected from fibrosis in the bleomycin mouse model of pulmonary fibrosis. We generated an IL-11 neutralising antibody that blocks lung fibroblast activation downstream of multiple stimuli and reverses myofibroblast activation. In therapeutic studies, anti-IL-11 treatment both prevented and reversed lung fibrosis, which was accompanied by diminished Erk activation. These data prioritise IL-11 as a drug target for lung fibrosis and IPF.

IL-6-mediated activation of STAT3M-NM-1 prevents trauma/hemorrhagic shock-induced liver inflammation

Project description:We previously demonstrated in rodents that T/HS results in liver injury that can be prevented by IL-6 administration at the start of resuscitation, however the mechanism(s) for the IL-6 protective effect is not fully known. We used microarrays to detail the global gene expression in response to T/HS and the effect of IL-6 on this model with and without pharmacologic blockade of Stat3-mediated IL-6 and identified distinct members of the inflammasome de-regulated during T/HS that normalized with IL-6 administration during resuscitation. Adult male rats were subjected to either sham procedure, a trauma plus hemorrhagic shock (T/HS) procedure, T/HS with IL-6 versus PBS during resuscitation, or pretreatment with pharmacologic blockade of Stat3-mediated IL6 via GQ-ODN and after procedural completion, animals were sacrificed and livers were taken and homegenized for RNA extraction and microarray analysis using Affymetrix Rat 230A GeneChipM-BM-. array

Gene expression profiles of mouse Blimp1 +/gfp and Blimp1 gfp/gfp regulatory T cells

Project description:Regulatory T (Treg) cells are required for peripheral tolerance. Recent evidence indicates that Treg cells can adopt specialized differentiation programs in the periphery that are controlled by transcription factors usually associated with T helper differentiation. We demonstrate that expression of the transcription factor Blimp1 defines a population of Treg cells that localize predominantly to mucosal sites and produces IL-10. Blimp1 is required for IL-10 production by these cells and for their tissue homeostasis. A list of differentially expressed genes were identified from this whole-genome expression profiling experiment. Mouse Blimp1 +/gfp and Blimp1 gfp/gfp regulatory T cells were analyzed. Three replicates each.

Transcriptome profiling of CD8+ T cells exposed to vehicle or IL-1b treatment in vivo

Project description:RNA sequencing analysis is capable of quantitatively analyzing transcriptome of a cell population at a genome-wide level. To determine the impact of systemic IL-1b administration on T cell differentiation in vivo, we adoptively transferred OT-I CD8+ T cells to a host, followed by OVA/LPS immunization and 3 daily injections of PBS or IL-1b. On day 4, OT-I cells from draining lymph nodes were sorted and the RNA was extracted for sequencing.

IL-31 regulation of transcripts in skin

Project description:Interleukin-31 (IL-31), a T cells derived cytokine which is mainly produced by CD4+ T cells skewed towards Th2 phenotypes. It signals via a heterodimeric receptors composed of IL-31RA and OSMR that is expressed constitutively in epithelial cells and keratinocytes. IL-31 is shown to play a pathogenic role in allergic and inflammatory diseases. Transgenic mice overexpressing IL-31 have a phenotype similar to atopic dermatitis. Here, we studied the role of IL-31 in skin damage by intradermal administration of recombinant IL-31. Notably, IL-31 was sufficient to increase epidermal basal cell proliferation and thickening of the epidermal layer of skin in mice. Analysis of skin transcriptome indicates a significant increase in the transcripts involved in epidermal cell proliferation and pathological skin remodeling. Thus, our study revealed an important role of IL-31 signaling in activating transcriptional programs involved in the pathophysiology of skin diseases.

Characterization of long-term IL-33 administration as an animal model of pulmonary arterial hypertension

Project description:Pulmonary arterial hypertension (PAH) is characterized by severe obstruction of small pulmonary arteries and concomitant high pulmonary arterial pressure, resulting in progressive right ventricular failure. Previously, we demonstrated that long-term interleukin (IL)-33 administration in mice induced severe occlusive arterial hypertrophy in the lung, which was mediated by group 2 innate lymphoid cells (ILC2s). In response to IL-33, ILC2s accumulated around blood vessels and produced IL-5, leading to perivascular eosinophil recruitment. In this study, we further characterized IL-33-induced pulmonary arterial hypertrophy. We first demonstrated that long-term IL-33 administration caused an increase in the right ventricular pressure. In IL-33 deficient mice, pulmonary arterial hypertrophy mediated by eggs of Schistosoma mansoni (S. mansoni) was attenuated, accompanied with partial reduction in ILC2s, eosinophils and CD4+ T cells. In addition, proteomic analysis revealed dramatic changes in urine samples from mice treated with IL-33 or S. mansoni eggs. Resistin like alpha (RELM), a pulmonary hypertension-related molecule, in the urine was commonly detected in both treatments. Large amounts of RELM were observed in the lung from IL-33-treated mice. These observations support that IL-33-induced pulmonary arterial hypertrophy is a useful model to study the mechanism underlying development of PAH and expolar biomarkers to indicate the onset of PAH.
