Expression data from adult rat subventricular zone cells

ABSTRACT: Transforming growth factor (TGF)-ß1 is a multifunctional cytokine regulating a number of physiological and patho-physiological processes in the adult brain. Its expression is elevated during neurodegeneration, which is associated with reduced levels of neurogenesis. We have postulated that TGF-ß1 might be one of the crucial factors involved in limiting neurogenesis in the diseased brain. We used microarrays to detail the gene expression profile after TGFbeta-1 treatment and identified distinct classes of up- and downregulated genes. Keywords: control versus TGFbeta1 treated group

Keywords: control versus TGFbeta1 treated group Adult rat subventricular zone cells were cultured for 7 days under proliferation conditions. Control cells were exposed to HCl/BSA whereas TGFbeta-1 treated cells received 10 ng/ml TGFbeta-1 dissolved in HCl/BSA 3 times per week. RNA was extracted followed by hybridization on Affymetrix microarrays.

Structural determinants of heparin–transforming growth factor-β1 interactions and their effects on signalling

Project description:Transforming growth factor-ß1 (TGF-ß1, Uniprot: P01137) is a heparin-binding protein that has been implicated in a number of physiological processes, including the initiation of chondrogenesis by human mesenchymal stem cells (hMSCs). Here, we identify the molecular features in the protein and in heparin required for binding and their effects on the potentiation of TGF-ß1’s activity on hMSCs. Using a proteomics “Protect and Label” approach, lysines K291, K304, K309, K315, K338, K373, K375 and K388 were identified as being directly involved in binding heparin. Competition assays in an optical biosensor demonstrated that TGF-ß1 does require N- and 6-O-sulfate groups for binding but that 2-O-sulfate groups are unlikely to underpin the interaction. Heparin-derived oligosaccharides as short as degree of polymerization (dp) 4 have a weak ability to compete for TGF-ß1 binding to heparin, which increases with the length of the oligosaccharide to reach a maximum between dp18 and dp24. In cell-based assays, heparin, 2-O-, 6-O- and N-desulfated re-N-acetylated heparin and oligosaccharides 14–24 saccharides (dp14–24) in length all increased the phosphorylation of SMAD2 after 6 h of stimulation with TGF-ß1. The results provide the structural basis for a model of heparin/heparan sulfate binding to TGF-ß1 and demonstrate that the features in the polysaccharide required for binding are not identical to those required for sustaining the signaling by TGF-ß1 in hMSCs.

Systematic investigation of cytokine signaling activity at the tissue and single-cell levels

Project description:Purpose: The role of different TGF-beta isoforms in tumor progression is not well established. The goal of the study was to assess the effect on the 4T1 mouse mammary tumor transcriptomes of treatment with isoform-selective anti-TGFbeta neutralizing antibodies to address whether sparing TGF-beta3 had any biological impact. Methods: 40,000 4T1 cells were implanted in the #4 mammary fatpad of syngeneic female BALB/c mice. Mice were treated with therapeutic or control antibodies (5mg/Kg i.p. 3x q wk) for 12 days prior to tumor harvest for RNA-Seq analysis. Treatments were: 1D11 pan-TGFbeta mouse monoclonal, XPA.42.681 pan-TGFbeta human monoclonal, XPA.42.089 anti-TGFbeta1+2 human monoclonal, anti-KLH control human monoclonal, 13C4 control mouse monoclonal, or vehicle control. Tumor mRNA profiles were generated by deep-sequencing of n=5 to 7 samples/treatment group using Illumina HiSeq2500 with TruSeq v4 chemistry. Results: 51-115 million pass-filtered reads were obtained for all samples, with >=91% of bases having a quality score of 30 or above.

Effect of simultaneous activation of TGFbeta and TLR4 pathway in human monocytes

Project description:To better understand the interaction of TGFbeta and Toll-like-receptor 4 (TLR4) signaling in monocytes, we performed microarray analysis. We identified a unique set of genes whose expressions in monocytes were regulated by simultaneous stimulation of TLR4 and TGFβ signaling. THP-1 cells, a human monocytic cell line, were stimulated for 24 hours with PBS as control, LPS (100ng/ml), TGFbeta1 (1ng/ml) or LPS (100ng/ml) + TGFbeta1 (1ng/ml). After 24 hours of stimulation, total RNA was isolated and prepared for genome wide analyses using Illumina HumanRef8 V3.0 Beadchips. In total 32 arrays were analyzed including 8 samples of PBS-stimulated monocytes, 8 samples of LPS-stimulated monocytes, 8 samples of TGFbeta1 stimulated monocytes and 8 samples of monocytes stimulated with LPS + TGFbeta1.

Transcription profiling of primary human tubular epithelial cells (HUTEC) response to TGFbeta at three concentrations to study the epithelial to mesenchymal transition

Project description:This experiment was aimed to study the Epithelial to mesenchimal transition (EMT) induced by TGFbeta in primary tubular epithelial cells. Primary cultures were grown for 4 days using three different TGFbeta1 concentrations: 5 ng/ml, 10 ng/ml and 50 ng/ml. Cells were grown in plastic flasks (Falcon) or in plastic flasks (Falcon) covered by type I collagen. Differentially expressed genes were identified comparing treated vs. control cells maintained for 4 days in 1% serum without TGFbeta1.

Primary and ras keratinocytes plus TGFbeta1

Project description:We have compared the response to TGFbeta1 in normal and v-rasHa transduced primary mouse keratinocytes using NCI cDNA microarrays. This analysis reveals that Ha-ras alters global TGFbeta1 mediated gene expression in a gene specific manner. The expression pattern of TGFbeta1 immediate early response genes and down regulation of cell cycle control genes is not altered by Ha-ras but the induction of most extracellular matrix genes is blocked. Using Smad3 null keratinocytes, we find that the majority of TGFbeta1 responsive genes in primary keratinocytes are Smad3 dependent, but patterns of transcriptional responses suggest that the ability of Ha-ras to block TGFbeta1 mediated gene expression is not dependent on Smad3. However, the combination of oncogenic ras and loss of Smad3 prevents the TGFbeta1 dependent suppression of genes associated with cell cycle progression and apoptosis observed with either genotype alone. In addition several extracellular matrix genes are super-repressed by TGFbeta1 in the Ha-ras Smad3 null keratinocytes. These data provide a genomic framework for understanding how disruptions of TGFbeta signaling and oncogenic ras cooperate to promote premalignant progression of primary keratinocytes. Keywords: time series design

TGFbeta lung fibroblasts

Project description:The response to a 4 hour treatment with TGFbeta (4 ng/ml) was evaluated in lung fibroblasts derived from three controls (normal periphery of resected tumor), open lung biopsies from three patients with idiopathic pulmonary fibrosis (usual interstitial pneumonia pattern on biopsy) and from three patients with fibrosing alveolitis associated with systemic sclerosis (fibrotic non specific interstitial pneumonia pattern on biopsy). Lung fibroblasts were grown to confluence in DMEM with 10% fetal calf serum. At confluence, lung fibroblasts were serum-deprived overnight, and exposed to either 4 ng/ml of activated TGF-ß1 (R&D Systems) or serum-free culture medium with 0.1% BSA for four hours.

Molecular characterization of adult mouse subventricular zone progenitor cells during the onset of differentiation

Project description:Adult mouse subventricular zone (SVZ) neural progenitor cells (NPCs) retain the capacity to generate multiple lineages in vitro and in vivo. Thus far, the mechanisms involved in the regulation of these cells have not been well elucidated. We have carried out RNA profiling of adult SVZ cell cultures undergoing differentiation, to identify pathways that regulate progenitor cell proliferation and to define a set of transcripts that can be used as molecular tools in the drug discovery process. We carried out a stepwise stratification of the results to identify transcripts specifically enriched in NPCs and validated some of these using comparative literature analysis, quantitative PCR and immunological techniques. The results show a set of transcription factors, secreted molecules, and plasma membrane markers which are differentially regulated during differentiation. Pathway analysis highlights alterations in IGF, Wnt and TGFbeta signalling cascades. Further characterization of these components could provide greater insight into the mechanisms involved in the regulation of neurogenesis in the adult brain. Keywords: time-course, differentiation comparison
