Project description:Our goal was to identify UTP-regulated genes in WT cADSC and P2Y₂ KO cADSC in the frame of the potential therapeutic transplantation of these cells into the mouse ischemic heart after a myocardial infarction. We identified UTP-regulated genes involved in inflammation and the immune response, UTP target genes linked to extracellular matrix organization such as matrix metallopeptidases and various collagen types, UTP-regulated genes related to macrophage chemotaxis and differentiation into pro-fibrotic foam cells and UTP target genes linked to angiogenesis regulation and the response to hypoxia.

Project description:We developed a new method to profile nascent RNA in mammalian cells. The new methodology is based on the incorporation of thio-UTP, an analog of UTP, during in vitro RNA Polymerase run-on.

Project description:Homing and engraftment of hematopoietic stem cells (HSCs) to the bone marrow (BM) involve a complex interplay between chemokines, cytokines, and non-peptide molecules. Extracellular nucleotides and their cognate P2 receptors are emerging as key-factors of inflammation and related chemotactic responses. In this study, we investigated the activity of extracellular adenosine-triphosphate (ATP) and uridine-triphosphate (UTP) on CXCL12-stimulated CD34+ HSC chemotaxis. In vitro, UTP significantly improved HSC migration, inhibited cell membrane CXCR4 down-regulation of migrating CD34+ cells and increased cell adhesion to fibronectin. In vivo, pre-incubation with UTP significantly enhanced the BM homing efficiency of human CD34+ cells in immunodeficient mice. Pertussis toxin blocked CXCL12- and UTP-dependent chemotactic responses, suggesting that G-protein alpha-subunits (Gαi) may provide a converging signal for CXCR4- and P2Y-activated transduction pathways. In addition, gene expression profiling of UTP-treated CD34+ cells and in vitro inhibition assays demonstrated that Rho guanosine 5’-triphosphatases (GTPase) Rac2 and downstream effectors Rho GTPase–activated kinases 1 and 2 (ROCK1/2) are involved in UTP-promoted/CXCL12-dependent HSC migration. Our data suggest that UTP may physiologically modulate the migration of HSCs and their homing to the BM, in concert with CXCL12, via the activation of converging signaling pathways between CXCR4 and P2Y receptors, involving Gαi proteins and RhoGTPases.

Project description:We have developed a multi-analyte fluid-phase protein array technology termed high-throughput immunophenotyping using transcription (HIT). This method employs a panel of monoclonal antibodies, each tagged with a unique oligonucleotide sequence that serves as a molecular barcode. After staining a sample, T7 polymerase amplifies the tags which are then hybridized to a DNA microarray for indirect measurement of each analyte. Here we coupled 44 of the tags to aliquots of an IgG1 isotype negative control antibody and the 4 remaining tags we coupled to anti-CD3, anti-CD4, anti-CD19, and anti-CD20 to create a 48-plex HIT cocktail. We then used this cocktail to stain 1 x 10^6 T or B cells and during amplification incorporated either cyanine 3-UTP (Cy3-UTP) or Cy5-UTP. Additionally, we snap froze and thawed an aliquot of the cocktail (FT). Keywords: protein profiling, cell type comparison

Experiment Overall Design: Highly purified CD34+ cells from 6 healthy donors were seeded at 1000000 cells/ml in serum free medium (EX vivo 15) w/o cytokines and treated with 10 mM UTP, 150ng/ml CXCL12, or 10 mM UTP plus 150ng/ml CXCL12 respectively for 24 hours. As a control, CD34+ untreated cells were maintained in the same culture conditions at the same time.
