ADAM17 is required for EGF-R induced intestinal tumors via IL-6 trans-signaling
  • organism-icon Mus musculus
  • sample-icon 38 Downloadable Samples
  • Technology Badge IconIllumina HiSeq 3000

Description

Colorectal cancer is treated with antibodies blocking epidermal growth factor receptor (EGF-R) but therapeutic success is limited. EGF-R is stimulated by soluble ligands, which are derived from transmembrane precursors by ADAM17-mediated proteolytic cleavage. In mouse intestinal cancer models in the absence of ADAM17, tumorigenesis was almost completely inhibited and the few remaining tumors were of low grade dysplasia. RNA-Seq analysis demonstrated downregulation of STAT3 and Wnt pathway components. Since EGF-R on myeloid cells, but not on intestinal epithelial cells is required for intestinal cancer and IL-6 is induced via EGF-R stimulation, we analyzed the role of IL-6 signaling. Tumor formation was equally inhibited in IL-6 -/- and sgp130Fc transgenic mice, in which only trans-signaling via soluble IL-6R is abrogated. ADAM17 is needed for EGF-R-mediated induction of IL-6 synthesis, which via IL-6 trans-signaling induces ß-catenin dependent tumorigenesis. Our data reveal the possibility of a novel strategy for treatment of colorectal cancer, which could circumvent intrinsic and acquired resistance to EGF-R blockade. Overall design: RNA sequencing of tumor tissue and surrounding unaffected tissue of Apc Min/+ and Apc Min/+ ::ADAM17 ex/ex

Gene expression profiles of trophoblast cell lines
  • organism-icon Homo sapiens
  • sample-icon 12 Downloadable Samples
  • Technology Badge Icon Affymetrix Human Genome U133A Array (hgu133a)

Description

Invasive extravillous trophoblasts (EVTs) of the human placenta are critically involved in successful pregnancy outcome since they remodel the uterine spiral arteries to increase blood flow and oxygen delivery to the placenta and the developing fetus. To gain more insights into their biological role different primary cell culture models are commonly utilised. However, access to early placental tissue may be limited and primary trophoblasts rapidly cease proliferation in vitro impairing genetic manipulation. Hence, trophoblastic cell lines have been widely used as surrogates to study EVT function. Although the cell lines share some molecular marker expression with their primary counterpart, it is unknown to what extent they recapture the invasive phenotype of EVT. Therefore, we here report the first thorough GeneChip analyses of SGHPL-5, HTR-8/SVneo, BeWo, JEG-3 and the novel ACH-3P trophoblast cells in comparison to previously analysed primary villous cytrophoblasts and extravillous trophoblasts.

Gene expression profiles of Wnt-1 overexpressing melanoma
  • organism-icon Homo sapiens
  • sample-icon 23 Downloadable Samples
  • Technology Badge Icon Affymetrix Human Genome U133 Plus 2.0 Array (hgu133plus2)

Description

We aimed to analyze the effects of Wnt-1 overexpression on the mRNA expression profile of human melanoma in a mouse xenograft model and correlated the results with then presence or absence of lymphangiogenesis and metastasis. Affymetrix gene expression analysis revealed activation of canonical and non-canonical targets genes in response to Wnt-1 as compared with controls. In regard to lymphangiogenic factors, the amount of VEGF-C was the single best marker to correlate with the amount of lymph-angiogenesis.

Gene expression signatures of HO-1 in BeWo cells
  • organism-icon Homo sapiens
  • sample-icon 4 Downloadable Samples
  • Technology Badge Icon Affymetrix Human Gene 1.0 ST Array (hugene10st)

Description

Heme Oxygenase-1 (HO-1) is expressed in many cancers and influences the growth, survivall and metastasis of tumors, however, the molecular mechanisms remains largely unknown. To identify a common mechanism of action of HO-1 in cancer, we studied the global effect of HO-1 on the transcriptome of multiple tumors. Genome-wide expression profiling of HO-1 expressing versus HO-1 silenced cancer cells and a further data mining analysis of the preexisting expression database of 190 human tumors of 14 cancer types led us to identify 14 genes, the expression of which correlated firmly and universally with that of HO-1 (P < 0.001). These genes included regulators of cell plasticity and extracellular matrix remodeling (MMP2, ADAM8, TGF1, BGN, COL21A1, PXDN), signaling (CRIP2, MICB), amino acid transport and glycosylation (SLC7A1 and ST3GAL2), estrogen and phospholipid biosynthesis (AGPAT2 and HSD17B1), protein stabilization (IFI30) and phosphorylation (ALPPL2). PXDN, one of the genes being co-expressed with HO-1, was selected for further analysis. Immunofluorescence and western blotting confirmed positive correlation of PXDN with HO-1 levels in BeWo cancer cells as well as co-localization in invasive extravillous trophoblast cells of first trimester placenta. Loss of HO-1 in BeWo cells correlated with reduced cell adhesion to Collagen type I, Fibronectin and Laminin. The adhesion-promoting effects of HO-1 were dependent on PXDN expression, as loss of PXDN in HO-1 expressing BeWo cells led to reduced cell attachment to Laminin and Fibronectin coated wells.

  • Technology Badge Icon Affymetrix Human Genome U133A Array (hgu133a)

Description

Invasion of cytotrophoblasts into uterine tissues is essential for placental development. To identify molecules regulating trophoblast invasion, mRNA signatures of purified villous (CTB, poor invasiveness) and extravillous (EVT, high invasiveness) trophoblasts isolated from first trimester human placentae and villous explant cultures, respectively, were compared using GeneChip analyses yielding 991 invasion/migration related transcripts. Several genes involved in physiological and pathologic cell invasion, including ADAM-12,-19,-28 as well as Spondin-2, were upregulated in EVT. Pathway prediction analyses identified several functional modules associated with either the invasive or the non-invasive trophoblast phenotype. One of the genes which were downregulated in the invasive mRNA pool, heme oxygenase-1 (HO-1), was selected for functional analyses. Real-time PCR analyses, Western blottting, and immunofluorescene of first trimester placentae and differentiating villous explant cultures demonstrated downregulation of HO-1 in invasive EVT as compared to CTB. Modulation of HO-1 expression in loss-of as well as gain-of function cell models (BeWo and HTR8/SVneo, respectively) demonstrated an inverse relationship of HO-1 expression with trophoblast migration in transwell and wound healing assays. Importantly, HO-1 expression led to an increase in protein levels and activity of the nuclear hormone receptor PPARgamma. Pharmacological inhibition of PPARgamma abrogated the inhibitory effects of HO-1 on trophoblast migration. Collectively, our results demonstrate that gene expression profiling of EVT and CTB can be used to unravel novel regulators of cell invasion. Accordingly, we identify heme oxygenase-1 as a negative regulator of trophoblast motility acting via upregulation of PPARgamma.

Description

Human cytotrophoblast organoid cultures were established from the villous trophoblast of first trimester placentas. We analyzed the global expression profile of the cytotrophoblast organoids (CTB-ORG) and compared to the profile of the tissue of origin i.e. villous cytotrophoblast (vCTB) as well as to differentiated syncytiotrophoblast (STB) and placental fibroblasts (FIB).
