Project description:The human cytomegalovirus (HCMV) encodes the chemokine receptor US28 that exhibits constitutive activity. NIH-3T3 cells stably transfected with US28 present a pro-angiogenic and transformed phenotype both in vitro and in vivo. We used gene expression profiling to determine how US28 constitutive activity modulates expression of genes compared to mock-transfected cells. Keywords: Comparison of stably transfected cell lines

NIH-3T3 cells stably transfected with US28 present a pro-angiogenic and transformed phenotype both in vitro and in vivo. We used gene expression profiling to determine how US28 constitutive activity modulates expression of genes compared to mock-transfected cells. Experiment Overall Design: We isolated RNA from two different clonal stable cell lines of NIH-3T3 cells transfected either either mock or US28-WT and analysed these 4 RNA samples using Affymetrix mouse genome arrays.

Project description:This is an investigation of whole genome gene expression level in tissues of mice stimulated by LPS, FK565 or LPS + FK565 in vivo and ex vivo. We show that parenteral administration of a pure synthetic Nod1 ligand, FK565, induces site-specific vascular inflammation in mice, which is prominent in aortic root including aortic valves, slight in aorta and absent in other arteries. The degree of respective vascular inflammation is associated with persistent high expression of proinflammatory chemokine/cytokine genes in each tissue in vivo by microarray analysis, and not with Nod1 expression levels. The ex vivo production of proinflammatory chemokine/cytokine by Nod1 ligand is higher in aortic root than in other arteries from normal murine vascular tissues, and also higher in human coronary artery endothelial cells (HCAEC) than in human pulmonary artery endothelial cells (HPAEC), suggesting that site-specific vascular inflammation is at least in part ascribed to an intrinsic nature of the vascular tissue/cell itself.

Project description:Constitutively found at high frequencies, the role for NK cell proliferation remains unclear. Here, a shift in NK cell function from predominantly producing interferon-? (IFN-?), a cytokine with proinflammatory and antimicrobial functions, to producing the immunoregulatory cytokine IL-10, is defined during extended murine cytomegalovirus infection. The NK cells driven to express IL-10 in vivo acquired responsiveness to IL-12 and IL-21 for IL-10 production, but neither cytokine was required for the endogenous response. In vitro studies with IL-2 to support proliferation and in vivo adoptive transfers into murine cytomegalovirus-infected mice demonstrated that NK cell proliferation and further division enhanced the change. During infection, the responding NK cells acquired histone modifications indicative of an open IL-10 gene, and an IL-10 response was proliferation dependent ex vivo if the NK cells had not yet expanded in vivo but independent if they had. Thus, a novel role for proliferation in supporting changing innate cell function is discovered. The chromatin status of ex vivo isolated NK cells during MCMV infection was investigated by ChIP-seq on histone epigenetic marks (H3K4m3, H3K27m3, H3K36m3) on day 0, day 1.5 and day 3.5 post infection.

Project description:ING proteins play an essential role in the control of a variety of cellular functions whose deregulation is associated with tumor formation and dissemination, such as proliferation, apoptosis, senescence or invasion. Accordingly, loss of function of ING proteins is a frequent event in many types of human tumors. In this report, we have studied the function of ING4, a member of the ING family of tumor suppressors, in the context of normal, non-transformed primary fibroblasts. We show that ING4 negatively regulates cell proliferation in this cell type. The antiproliferative action of ING4 requires its ability to recognize chromatin marks, it is p53-dependent and it is lost in an ING4 cancer-associated mutant. Gene expression analysis shows that ING4 regulates the expression and release of soluble factors of the chemokine family. The secretory phenotype regulated by ING4 in primary fibroblasts displays a selective paracrine effect on proliferation, fostering the division of tumor cells, while inhibiting division in primary fibroblasts. Consistently, ING4-expressing fibroblasts promoted tumor growth in vivo in co-injection tumorigenesis assays. Collectively, our results show that ING4 not only can regulate the proliferation of primary non-transformed human fibroblasts, but also orchestrates a secretory phenotype in these cells that promotes tumor cell proliferation in vitro and in vivo. These findings support a critical role for ING4 expression in normal cells in the non-cell autonomous regulation of tumor growth. Gene expression analysis shows that ING4 regulates the expression and release of soluble factors of the chemokine family. Two independent retroviral infections were performed in early pasaje IMR-90 fibroblasts with wild-type ING4 wild type and the N214D mutant. All of them were hibridazed by duplicate againts a reference sample from vector-infected cells
