Expression data from mouse heart with and without GATA4 S105A mutation; with and without adrenergic stress

ABSTRACT: Serine 105 phosphorylation of GATA4 is necessary for stress-induced cardiac hypertrophy in vivo. We used microarrays to detail global gene expression program alterations that arise in response to the ablation of the Gata4 S105 phosphorylation site in basal and adrenergic-stressed heart ventricles. Wildtype and genetically engineered mice were subjected to control or pseudoephedrine treatment and heart ventricle RNAs were extracted and hybridized on Affymetrix microarrays. Comparisons consisted of identifying treatment- and genotype-affected gene expression patterns.

Parsing the roles of transcription factors Gata4 and Gata6 in adult cardiac hypertrophic responses

Project description:Cardiac hypertrophy is regulated by the zinc finger-containing DNA binding factors Gata4 and Gata6, both of which are required to mount a productive growth response of the adult heart. To determine if Gata4 and Gata6 are redundant or have non-overlapping roles, we performed cardiomyocyte-specific conditional gene deletions for Gata4 and Gata6 in conjunction with reciprocal replacement with a transgene encoding either Gata4 or Gata6, during the pressure overload response. We determined that Gata4 and Gata6 play a redundant and dosage-sensitive role in programming the hypertrophic growth response itself following pressure overload stimulation. However, non-redundant functions were identified as functional decompensation induced by either Gata4 or Gata6 deletion was not rescued by the reciprocal transgene, and only Gata4 heart-specific deletion produced a reduction in capillary density after pressure overload. Gene expression profiling from hearts of these gene-deleted mice showed both overlapping and unique transcriptional codes, with Gata4 exhibiting the strongest impact. These results indicate that Gata4 and Gata6 play a dosage-dependent and semi-redundant role in programming cardiac hypertrophy, but that each has a unique role in maintaining cardiac homeostasis and adaptation to injury that cannot be compensated by the other. Microarray-bassed gene expression profiling identified overlapping, distinct, and quantitatively/differentially regulated classes of Gata4 or Gata6 regulated genes. To determine if Gata4 and Gata6 are redundant or have non-overlapping roles in programming cardiac hypertrophic responses and adaptation to stress or injury, we performed cardiomyocyte-specific conditional gene deletions for Gata4 and Gata6 in conjunction with reciprocal replacement with a transgene encoding either Gata4 or Gata6, during the pressure overload response.

Skeletal muscle myoblasts: GATA4-Wt, -KO, -OE; day 0, 3

Project description:Gene expression in satellite cell-derived primary myoblasts islolated from Gata4-loxP mice. Myoblasts were infected with nLacZ for control (Wt), Cre recombinase to knockout GATA4 (KO), or GATA4 expression vector to overexpress GATA4 (OE). Infected myoblasts were cultured in growth medium (day 0) then differentiated into myotubes in differentiation medium for 3 days (day 3). Total 18 samples. Three replicates in each myoblast; GATA4-Wt, -KO, and -OE myoblasts at day 0 and day 3.

Comparison of cardiomyocyte transcripts after knockdown of Gata4 in zebrafish embryos

Project description:The Gata4 transcription factor is essential for normal heart development, but the molecular basis for its function remain poorly understood. We profiled at the whole genome level transcript changes in cardiomyocytes when Gata4 is depleted from zebrafish embryos. Our objective was to elucidate the cardiomyocyte-specific molecular program functioning downstream of Gata4 in order to better understand the role of Gata4 in cardiac morphogenesis. Six samples in total are deposited. Three replicate control samples and three replicate Gata4 morphant samples were analyzed.

Transcriptome profiling of GATA4 depleted hepatocytes

Project description:Analysis of changes in gene expression following hepatocyte specific deletion of GATA4 in adult mice. Results showed that the subset of differentially expressed genes had liver specific ontologies. Total RNA isolated from hepatocytes of AAV8-Tbg-Cre injected GATA4 fl/fl mice was compared to total RNA isolated from AAV-Tbg-GFP injected GATA4 fl/fl mice.

ChIP-seq of GATA4 in mouse skeletal muscle myoblasts

Project description:GATA4 occupancy on the mouse genome of satellite cell-derived primary myoblasts. Proliferating myoblasts cultured in growth medium were immunoprecipitated with anti-GATA4 antibody or control IgG. Precipitated genomic DNAs were subjected to next generation sequencing. Paired-end 150 bp sequence reads of GATA4-ChIP and IgG-ChIP using mouse skeletal muscle myoblasts.

ChIP-seq analysis of GATA4 in whole liver of adult mice

Project description:GATA4 regulates the liver development, but it's function and the gene transcriptional programs it regulates in the adult liver is unknown. In this study, we determined the genome-wide occupancy sites of GATA4 by performing ChIP-seq of whole livers. We have identified 4409 GATA4 enrichment peaks using two peak calling methods and irreproducible discovery rate (IDR) analysis. This corresponds to 3075 genes with GATA4 peaks within -5 kb of transcription start site (TSS) and +5 kb of transcription termination site (TTS). MEME analysis shows that approximately 90% of the peaks have the WGATAR motif, suggesting direct binding by GATA4. The peaks containing the WGATAR motif have a ChIP-seq higher tag enrichment score than peaks lacking the motif. Genome Regions Enrichment of Annotations Tool (GREAT) analysis of genes bound by GATA4 identified ontologies with liver specific functions. In summary, our study shows for the first time genome-wide occupancy profile of GATA4in the adult mouse liver. ChIP-sequencing of whole mouse livers from 2-3 month old mice

Genome-wide analysis of gene expression in TM4 Sertoli cells following siRNA-mediated Gata4 inhibition

Project description:The effects of Gata4 inhibition on global gene expression in TM4 Sertoli cells was analyzed. Using microarray analysis we identified a set of genes that are downregulated or upregulated following siRNA-mediated silencing of Gata4 in the murine Leydig tumor cell line mLTC-1. Among the downregulated genes were enzymes of the androgen biosynthetic pathway. TM4 cells were transfected with non-targeting (NT) siRNA and Gata4 siRNA respectively. 72h post transfection cells were lysed and RNA was extracted. n=3 of each sample group; control samples are samples 3-6 (TM4 cells treated with non-targeting siRNA)
