RNA-seq analyses of STAT1-delta IEC ApcMin (n=3) and STAT1-flox/flox ApcMin (n=3) mice

Project description:The interferon-inducible transcription factor STAT1 is a tumor suppressor in various malignancies. We investigated STAT1 functions in intestinal tumorigenesis of ApcMin mice. Surprisingly, loss of STAT1 in intestinal epithelial cells (STAT1ΔIEC) interfered with ApcMin induced intestinal tumor formation and tumor progression. RNASeq data demonstrated reduced expression of Indoleamine-2,3-dioxygenase-1 (IDO1) in STAT1ΔIEC ApcMin tumors. IDO1 is implicated in synthesis of kynurenine, a metabolite that induces ß-Catenin nuclear localisation and suppresses anti-tumor immune responses.

Comparative expression data between tumor epithelium of APCmin/+ FSPCre-PPARB -/- and PPARB flox/flox

Project description:Stroma secretes complex regulatory signals, including reactive oxygen species, that are involved in mediating cancer development. Ablation of PPARB expression in fibroblastic cells results in modulation of oxidative stress signals that lead By means of gene expression analysis, we seek to identify key gene expression changes in tumor epithelial cells between FSPCre-PPARB -/- and PPARB flox/flox mice.

CSF1R mediates effects of miR-34a loss during intestinal tumorigenesis in ApcMin mice (adenoma)

Project description:To address the in vivo relevance of CSF1R regulation by miR-34a during intestinal tumor formation, we generated ApcMin/+ mice with intestinal-epithelial cell (IEC)-specific deletions of the Mir34a and/or Csf1r genes. The mRNA expression profiles of intestinal adenomas with and without functional miR-34a and/or Csf1r were compared.

CSF1R mediates effects of miR-34a loss during intestinal tumorigenesis in ApcMin mice (tumor organoid)

Project description:To address the in vivo relevance of CSF1R regulation by miR-34a during intestinal tumor formation, we generated ApcMin/+ mice with intestinal-epithelial cell (IEC)-specific deletions of the Mir34a and/or Csf1r genes. The mRNA expression profiles of tumor organoids derived ffrom intestinal adenomas with and without functional miR-34a and/or Csf1r were compared.

Expression profile of WT and IKKb(EE)IEC epithelial cells (IEC)

Project description:To investigate NF-kB-driven gene expression in IEC, we performed microarray analysis from enterocytes of mice that express a constitutively active form of IKKb in intestinal epithelial cells Total RNA was prepared from enterocytes obtained from small intestines of IKKb(EE)IEC and WT littermates. Two biological replicates were performed for each experimental condition.

Microarray analysis of ApcMin/+ and D6(ACKR2)-/-ApcMin/+ tumors

Project description:Mast cells have been suggested to either promote or suppress tumor progression but the mechanisms underlying these outcomes are unclear. Here, we show that mice with a heterozygous mutation in the adenomatous polyposis coli gene (ApcMin/+) displayed reduced intestinal tumor burden and increased survival in the background of the chemokine decoy receptor ACKR2 deficiency (ACKR2-/-). The ACKR2-/-ApcMin/+ tumors showed increased infiltration of mast cells. In mast cell-deficient Sash (c-kitW-sh/W-sh) ACKR2-/-ApcMin/+ mice the survival advantage was lost as the tumors grew rapidly and adoptive transfer of mast cells reduced the tumor burden in these mice. The tumor burden is also increased in Rag2-/-ACKR2-/-ApcMin/+ mice and the protection is reconstituted by adoptively transferred CD8+ T-lymphocytes. Mast cells from ACKR2-/- mice expressed elevated levels of chemokine receptors CCR2 and CCR5 and are also efficient in antigen presentation and activation of CD8+ T-cells. Mast cell-derived leukotriene B4 is a critical mediator of CD8+ T-lymphocyte recruitment as the BLT1-/-ACKR2-/-ApcMin/+ mice are highly susceptible to intestinal tumor induced mortality. Taken together, these data demonstrate that chemokine mediated mast cell recruitment is essential for initiating LTB4/BLT1 regulated CD8+ T-cell homing and generation of effective anti-tumor immunity against intestinal tumor development.

Genome-wide analysis expression of ileum tumor samples from FVBN/APCmin and iPGC-1β/APCmin

Project description:Analysis of metabolic pathway gene expression. The hypothesis tested in the present study is to assess mRNA level changes in metabolic genes in intestinal tumors from APCmin mice overexpressing PGC-1β specifically in the intestine. Total RNA obtained from ileum tumor samples from iPGC-1β/APCmin mice was compared to the total RNA extracted from FVBN/APCmin mice.

Genome-wide analysis of gene expression profile of Intestinal (ILEUM) Tumors from APCmin/+/VP16LXRa vs APCmin/+/VP16

Project description:Changes in gene expression profile of intestinal (ILEUM) Tumors from APCmin/+/VP16LXRa vs APCmin/+/VP16. The hypothesis tested in the present study was that LXRa overexpression influence cancer growth modulating lipid metabolism in cancer cells. Results provide the information that LXRa induces genes encoding proteins able to regulate cholesterol efflux. Total RNA obtained from Ileum tumors from APCmin/+/VP16LXRa mice was compared to total RNA extracted from APCmin/+/VP16 mice.
