Transcription profiling of mouse Ngn3-expressing pancreatic cells in a time series through embryonic development and adult islet cells

Project description:Neurogenin3 (Ngn3) is a basic helix-loop-helix transcription factor which is expressed in scattered cells in the embryonic pancreas. Mice deficient for Ngn3 fail to produce any pancreatic endocrine cells and die shortly after birth. Expression of transcription factors critical to pancreatic development (Isl1, NeuroD, Pax4, and Pax6) is missing and endocrine precursors are absent in mutant pancreatic epithelium. This study utilizes mice which were engineered to contain EGFP (Enhanced Green Fluorescent Protein) under the control of the Ngn3 promoter. In this way, cells which express Ngn3 can be FACS sorted and studied throughout embryonic development (E13.5, E14.5, E15.5, E16.5, and E17.5). EGFP positive cells from the embryonic time-points in addition to adult islets (no cells expressing Ngn3) were hybridized to the BCBC PancChip 6.0 expression microarray, thus generating a profile of gene expression during this critical stage of development of the endocrine pancreas.

Transcription profiling of mouse wild type and Nkx2.2 mutant embryos at E12.5 and E13.5 to identify a transcripional program that Nkx2.2 regulation in the pancreas

Project description:The goal of this experiment was to analyze expression changes in the pancreas at embryonic days 12.5 and 13.5 between wild type and Nkx2.2 null mice. We know that Nkx2.2 is essential for pancreatic endocrine differentiation and development. At these early time points which are critical for endocrine cell specification, we would like to identify a transcriptional program that Nkx2.2 regulates. We would also like to identify direct and functional transcriptional targets of Nkx2.2.

Transcription profiling of rat insulinoma-beta (INS-1E) cells exposed to the cytokines IL-1-beta and IFN-gamma for six different lengths of time and with or without the inducible NO synthase blocker NMA

Project description:Locally released cytokines contribute to beta cell dysfunction and apoptosis in Type 1 diabetes. In vitro exposure of insulin producing INS-1E cells to the cytokines interleukin (IL)-1beta + interferon (IFN) gamma leads to a significant increase in apoptosis. To characterize the genetic networks implicated in beta cell dysfunction and apoptosis and its dependence on nitric oxide (NO) production, we performed a time course analysis using the Affymetrix RG U34A microarry. INS-1E cells were exposed in duplicate to IL-1beta + IFN-gamma for six different time points (1, 2, 4, 8, 12, and 24 h) with or without the inducible NO synthase blocker.

Chromatin immunoprecipitation of wild type and Foxa2 knock-out mouse liver using anti-HNF6 anitbodies to test whether Foxa2 inhibits HNF6-mediated transcription in the liver

Project description:The aim of this study was to test, in vivo, if Foxa2 inhibits HNF6-mediated transcription in the liver. We utilized hepatocyte-specific gene ablation of Foxa2 and the Mouse PromoterChip BCBC 3.0 and Mouse PancChip 5.0 cDNA microarrays to investigate HNF6 binding to its target promoters in vivo in the presence or absence of Foxa2. For the mouse promoter microarray analysis, chromatin immunoprecipitation using anti-HNF6 antibodies was performed on chromatin isolated from Foxa2loxP/loxP Alfp.Cre and control mouse livers. Along with sheared genomic DNA (common reference), the immunoprecipitated DNA was amplified, labeled and hybridized to the Mouse PromoterChip BCBC 3.0. For microarray analysis of gene expression, liver RNAs were isolated from three Foxa2loxP/loxP Alfp.Cre and three control mice. RNAs were reverse transcribed, labeled, and hybridized to the Mouse PancChip 5.0. Overall, our studies demonstrate that HNF6 binds to and regulates its target promoters in vivo in the presence and absence of Foxa2 and that the expression levels of HNF6 targets are not influenced by Foxa2.

arabidopsis ecotypes-Transcriptionnal response to potyviruses infection in Arabidopsis

Project description:ra06-05_potyvirus-ecotypes - arabidopsis ecotypes - Common and specific genes deregulated in response to various potyviruses in different Arabidopsis genetic backgrounds. - Four different Arabidopsis ecotypes were inoculated with one Potyviruse. About 4 weeks after sowing, the 6 expanded leaves plants were inoculated with the different viruses or were mock-inoculated. Seven days after inoculation, inoculated leaves were collected, RNA was extracted and virus infection controlled. RNA fron infected plants was then used for microarrays hybridization. Three biological repeat have been done and two dye-swap. Keywords: normal vs disease comparison 6 dye-swap - CATMA arrays

Transcription profiling of mouse skeletal muscle in streptozotocin diabetes with or without insulin treatment

Project description:Metabolic abnormalities underlying diabetes are primarily the result of the lack of adequate insulin action and the associated changes in protein phosphorylation and gene expression. Affymetrix oligonucleotide microarrays were used to study the changes in the transcriptional program of mouse skeletal muscle in insulin-deficient diabetes. Mice which were made diabetic by streptozotocin treatment were compared to controls. Also, the reversibility of these changes was ascertained by treating a subset of the diabetic mice with insulin.

Transcription profiling of human CMV-stimulated CD69+, hCMV-stimulated CD69- and unstimulated monoclonal CD4+ T-LGL lymphocytes from peripheral blood samples from four TCRVbeta+/CD4+ T-LGL lymphocytosis patients

Project description:Recent studies suggest the potential involvement of common antigenic stimuli on the ontogeny of monoclonal TCRalphabeta+/CD4+/NKa+/CD8-/+dim T-large granular lymphocyte (LGL) lymphocytosis. Since healthy individuals show (oligo)clonal expansions of hCMV-specific TCRVbeta+/CD4+/cytotoxic/memory T-cells, we investigate the potential involvement of hCMV in the origin and/or expansion of monoclonal CD4+ T-LGL. A detailed characterization of those genes that underwent changes in T-LGL cells responding to hCMV was performed by microarray gene expression profile (GEP) analysis. Experiment Overall Design: Total RNA was isolated from magnetic-activated cell sorter (MACS)-freshly purified hCMV-stimulated CD69+, hCMV-stimulated CD69- and unstimulated monoclonal CD4+ T-LGL lymphocytes from PB samples from four TCRVbeta+/CD4+ T-LGL lymphocytosis patients (purity of â?¥98%). Briefly, 100 ng of total RNA from each of the 12 purified cell fractions was amplified and labeled using the GeneChip two cycle cDNA synthesis kit and the GeneChip IVT labeling kit (Affymetrix Inc., Santa Clara, CA), respectively. Then it was hybridized to the Human Genome U133 Plus 2.0 Array (Affymetrix). Experiment Overall Design: In parallel, total RNA was also isolated from highly purified (â?¥ 98% purity) hCMV-stimulated (specific) CD69+ CD4+ T-lymphocytes isolated from PB samples from hCMV-seropositive healthy donors (n=5, mean age of 36 years) using a FACSAria flow cytometer (BDB). To get pure and highly concentrated RNA, the silica membrane technology NucleoSpinÂ® RNA XS (Macherey-Nagel, DÃ¼ren, Germany) was used. Total RNA was then amplified, labeled and hybridized to the Human Genome U133 Plus 2.0 Array (Affymetrix) as described above.

Transcription profiling of pig aortic endothelial cells to investigate the impact of gender, high fat/high cholesterol diet and regional hemodynamics on gene expression

Project description:Atherosclerosis preferentially develops in susceptible regions of the arterial system that are defined by the regional vascular hemodynamics. Previous work in adult castrate male pigs revealed the coexistence of pro- and anti-atherosclerotic profiles in endothelial cell gene expression in disturbed flow regions of arteries in the absence of risk factors for atherogenesis. This study investigates the impact of gender, high fat/high cholesterol diet and regional hemodynamics on arterial endothelial cell gene expression profiles in sexually mature intact pigs.
