Project description:RNA-seq data indicated that Knockdown of GATA4 in human cardiomyocytes resulted in differential alternative splicing changes in genes involved in cytoskeleton organization and calcium ion import. Enhanced crosslinking and immunoprecipitation (CLIP) assay demonstrated that GATA4 directly binds to defined mRNAs motifs in a sequence-specific manner

Project description:Using a systems biology approach, we discovered and dissected a three-way interaction between the immune system, the intestinal epithelium, and the microbiota. We found that mice lacking B lymphocytes, or lacking IgA, have low intestinal expression of lipid metabolism genes regulated by the transcription factor GATA4, and a consequent decrease in fat absorption in the intestine. The defect disappeared in germ free mice, suggesting that it is dependent on the microbiota; and sequencing analysis of the bacteria showed subtle differences between normal and B-cell deficient mice. Analysis of gene expression of gut biopsies from patients with common variable immunodeficiency and intestinal dysfunction revealed a high similarity to mouse B-cell knockout profiles. These data provide an explanation for a longstanding enigmatic association between immunodeficiency and defective lipid absorption in humans. This series represents the subsection of the study where we address the role of transcription factor Gata4. The data are from conditional KO (Gata4KOvil) and corresponding control mice.

This series represents the subsection of the study where we address the role of transcription factor Gata4. The data are from conditional KO (Gata4KOvil) and corresponding control mice. Intensity of each channel was extracted from two-color arrays. We used direct dye swap design and performed paired analysis between small intestine of KO and control mice. Corresponding paires of KO and control were hybridized on the same array, except pair X

Project description:DNA methylation changes dynamically during development and is essential for embryogenesis in mammals. However, how DNA methylation affects developmental gene expression and cell differentiation remains elusive. During embryogenesis, many key transcription factors are used repeatedly, triggering different outcomes depending on the cell type and developmental stage. Here, we report that DNA methylation modulates transcription-factor output in the context of cell differentiation. Using a drug-inducible Gata4 system and a mouse embryonic stem (ES) cell model of mesoderm differentiation, we examined the cellular response to Gata4 in ES and mesoderm cells. The activation of Gata4 in ES cells is known to drive their differentiation to endoderm. We show that the differentiation of wild-type ES cells into mesoderm blocks their Gata4-induced endoderm differentiation, while mesoderm cells derived from ES cells that are deficient in the DNA methyltransferases Dnmt3a and Dnmt3b can retain their response to Gata4, allowing lineage conversion from mesoderm cells to endoderm in part. Transcriptome analysis of the cells' response to Gata4 over time revealed groups of endoderm and mesoderm developmental genes whose expression was induced by Gata4 only when DNA methylation was lost, suggesting that DNA methylation restricts the ability of these genes to respond to Gata4, rather than controlling their transcription per se. Our data indicate that epigenetic regulation by DNA methylation functions as a heritable safeguard to prevent transcription factors from activating inappropriate downstream genes, thereby contributing to the restriction of the differentiation potential of somatic cells.

To understand how mouse cells differentially respond to Gata4 in cell type- and DNA methylation-dependent manners and to examine what genes are differentially regulated, we analyzed temporal change of gene expression profile in response to Gata4 in ES or Flk1(+) mesoderm cells in WT and Dnmt3a-/-Dnmt3b-/- (DKO) background, in total 108 samples.

Project description:The nucleosome is a fundamental unit of chromatin in eukaryotes, and generally prevents the binding of transcription factors to genomic DNA. Pioneer transcription factors overcome the nucleosome barrier, and bind their target DNA sequences in chromatin. OCT4 is a representative pioneer transcription factor that plays a role in stem cell pluripotency. In the present study, we biochemically analyzed the nucleosome binding by OCT4. Crosslinking mass spectrometry showed that OCT4 binds the nucleosome.
