Kinetic analysis of TGFbeta-induced EMT in NMuMG/E9 cells
  • organism-icon Mus musculus
  • sample-icon 44 Downloadable Samples
  • Technology Badge IconIllumina HiSeq 2000

Description

To investigate the transcriptional remodelling during EMT, we treated normal murine mammary gland epithelial cells with TGFbeta for 0, 2h, 6h, 12h, 24h, 36h, 48h, 60h, 72h, 96h, 168h and 240h. Using WGCNA and pathway enrichment analysis we identified multiple gene expression modules that were enriched in general, signaling, metabolic or stuctural pathways highly relevant for EMT. Overall design: RNA sequencing of NMuMG/E9 cells induced to undergo EMT by treatment with TGFbeta from 0-10 days.

TL1A signaling enhances the differentiation of TH9 cells and TH9-driven mucosal pathologies via BATF and BATF3 signaling pathways
  • organism-icon Mus musculus
  • sample-icon 4 Downloadable Samples
  • Technology Badge IconIon Torrent Proton

Description

The TNF family member TL1A (TNFSF15) co-stimulates several T helper subsets and promotes T cell-dependent models of inflammatory diseases, including inflammatory bowel diseases (IBD) and allergic lung disease. TL1A polymorphisms confer susceptibility to IBD and have been associated with disease severity. In this study, we identified TL1A as a strong inducer of TH9 cell differentiation in vitro. Mechanistically, TL1A induced NF-?B signaling and down-stream STAT6 activation and facilitated cooperative binding of BATF, BATF3, and IRF4 to the Il9 promoter. In vivo, utilizing an adoptive T cell transfer model we demonstrated that TL1A promoted IL-9-dependent, TH9 cell-induced intestinal and lung inflammation and blocking anti-IL-9 antibodies attenuated TL1A-driven mucosal inflammation. Our results demonstrate that TL1A promotes TH9 cell differentiation and function and define a role for IL-9 in TL1A-induced mucosal inflammation. Overall design: 4 samples (2x2)

HSF1-dependent and -independent regulation of the mammalian in vivo heat shock response and its impairment in Huntington's disease
  • organism-icon Mus musculus
  • sample-icon 24 Downloadable Samples
  • Technology Badge IconIllumina HiSeq 2000

Description

The heat shock response (HSR) is a mechanism to cope with proteotoxic stress by inducing the expression of molecular chaperones and other heat shock response genes. The HSR is evolutionarily well conserved and has been widely studied in bacteria, cell lines and lower eukaryotic model organisms. However, mechanistic insights into the HSR in higher eukaryotes, in particular in mammals, are limited. We have developed an in vivo heat shock protocol to analyze the HSR in mice and dissected heat shock factor 1 (HSF1)-dependent and -independent pathways. Whilst the induction of proteostasis-related genes was dependent on HSF1, the regulation of circadian function related genes, indicating that the circadian clock oscillators have been reset, was independent of its presence. Furthermore, we demonstrate that the in vivo HSR is impaired in mouse models of Huntington's disease but we were unable to corroborate the general repression of transcription after a heat shock found in lower eukaryotes. Overall design: RNA-Seq was performed on mRNA isolated from quadriceps femoris muscle of 24 mice. These mice were of wild type, R6/2, and Hsf1-/- genotypes. Two mice of each genotype were tested in four conditions: (1) heat shock, (2) control heat shock, (3) HSP90 inhibition (NVP-HSP990), and (4) HSP90 inhibition vehicle.

  • sample-icon 30 Downloadable Samples
  • Technology Badge IconIllumina HiSeq 2000

Description

Purpose: Transcriptome profiling (RNA-seq) to microarray to evaluate transcriptional changes in the heart of HD mouse models Methods: Heart mRNA profiles of 4-weeks-old wild-type (WT) and R6/2 transgenic; 15-weeks-old WT and R6/2 transgenic mice; 8-month-old WT and HdhQ150 knock-in mice; 22-month-old WT and HdhQ150 knock-in mice were generated by deep sequencing, in triplicate, using Illumina Hi-seq 2000. Conclusions: Our study showed that there is no major transcriptional deregulation in the heart of mouse models of HD. Overall design: Heart mRNA profiles of 4-weeks-old wild-type (WT) and R6/2 transgenic; 15-weeks-old WT and R6/2 transgenic mice; 8-month-old WT and HdhQ150 knock-in mice; 22-month-old WT and HdhQ150 knock-in mice were generated by deep sequencing, in triplicate, using Illumina Hi-seq 2000.

Transcription profiling by array of human lung cancer cells after treatment with dasatinib, imatinib, nilotinib or PD0325901
  • organism-icon Homo sapiens
  • sample-icon 111 Downloadable Samples
  • Technology Badge Icon Affymetrix HT Human Genome U133A Array (hthgu133a)

Description

Cell Line: This experiment was designed to measure the transcriptional responses to four kinase inhibitors across a five-logarithm dose range. The A549 human lung cancer cell line was treated with dasatinib, imatinib or nilotinib (4 hours and 20 hours) or PD0325901 (4 hours). Treatments used a 12-point dose range (30 uM with 3-fold dilutions down to 0.17 nM; 0.5% DMSO vehicle for all treatments). Experimental design prevented row or column handling effects being confounded with dose effect.

Gene expression profiling of colitis-associated and sporadic colorectal tumors in mice
  • organism-icon Mus musculus
  • sample-icon 14 Downloadable Samples
  • Technology Badge Icon Affymetrix Mouse Expression 430A Array (moe430a)

Description

To uncover molecular mechanisms specifically involved in the pathogenesis of colitis-associated colon cancer (CAC), we studied tumorigenesis in experimental models of CAC and sporadic CRC that mimic characteristics of human CRC. Using comparative whole genome expression profiling, we observed differential expression of epiregulin (Ereg) in mouse models of colitis-associated, but not sporadic colorectal cancer. Similarly, highly significant upregulation of Ereg expression was found in cohorts of patients with colitis-associated cancer in inflammatory bowel disease but not in sporadic colorectal cancer. Furthermore, tumor-associated fibroblasts were identified as major source of Ereg in colitis-associated neoplasias. Functional studies showed that Ereg-deficient mice, although more prone to colitis, are strongly protected from colitis-associated tumors, and data from serial endoscopic studies revealed that Ereg promotes growth rather than initiation of tumors.

Gene Expression Changes in Primary Human Nasal Epithelial Cells exposed to Formaldehyde in vitro
  • organism-icon Homo sapiens
  • sample-icon 36 Downloadable Samples
  • Technology Badge Icon Affymetrix Human Genome U133 Plus 2.0 Array (hgu133plus2)

Description

Using various exposure conditions, we studied the induction of DNA-protein crosslinks (DPX) by formaldehyde (FA) and their removal in primary human nasal epithelial cells (HNEC). DPX were indirectly measured by the alkaline comet assay as the reduction of gamma ray induced DNA migration. DPX are the most relevant primary DNA alterations induced by FA and the comet assay is a very sensitive method for the detection of FA-induced DPX. In parallel experiments, we investigated changes in gene expression by using a full genome human microarray. After a single treatment with FA (50 to 200 M), concentration and time-dependent changes in gene expression were seen under conditions that also induced genotoxicity. Repeated treatments with low FA concentrations (20 and 50 M) did not lead to a significant induction of DPX but repeated treatments with 50 M FA changed the expression of more than 100 genes. Interestingly, the expression of genes involved in the main pathway for FA detoxification and the repair of DPX were not specifically enhanced. A high degree of overlap was seen among the pattern of gene changes induced by FA in HNEC in comparison to recently published array studies for nasal epithelial cells from rats exposed to FA in vivo. Our results suggest that HNEC are a suited in vitro model for the characterization of FA-induced toxicity and the relationship between genotoxic and other cytotoxic effects.
