GATA-3 is a proto-oncogene in T-cell lymphoproliferative neoplasms [RNA-seq]

ABSTRACT: In order to identify GATA-3 target genes in T-cell lymphoproliferative neoplasms, we performed GATA-3 ChIP-seq on 3 cutaneous T-cell lymphoma (CTCL) and 4 T-cell acute lymphoblastic leukemia (T-ALL). We have also established cell lines in which GATA-3 was knocked down by shRNA.

GATA-3 is a proto-oncogene in T-cell lymphoproliferative neoplasms.

Project description:Neoplasms originating from thymic T-cell progenitors and post-thymic mature T-cell subsets account for a minority of lymphoproliferative neoplasms. These T-cell derived neoplasms, while molecularly and genetically heterogeneous, exploit transcription factors and signaling pathways that are critically important in normal T-cell biology, including those implicated in antigen-, costimulatory-, and cytokine-receptor signaling. The transcription factor GATA-3 regulates the growth and proliferation of both immature and mature T cells and has recently been implicated in T-cell neoplasms, including the most common mature T-cell lymphoma observed in much of the Western world. Here we show that GATA-3 is a proto-oncogene across the spectrum of T-cell neoplasms, including those derived from T-cell progenitors and their mature progeny, and further define the transcriptional programs that are GATA-3 dependent, which include therapeutically targetable gene products. The discovery that p300-dependent acetylation regulates GATA-3 mediated transcription by attenuating DNA binding has novel therapeutic implications. As most patients afflicted with GATA-3 driven T-cell neoplasms will succumb to their disease within a few years of diagnosis, these findings suggest opportunities to improve outcomes for these patients.

Role of GATA-2 -77 enhancer in murine blood progenitor cells

Project description:We discovered enhancers that control GATA-2 expression during mouse development and in adult and generated mutant mouse strains that lack these enhancers, and these mice have very specific and important phenotypes that revealed GATA-2 mechanisms to control stem and progenitor cell transitions. In this study we aim to determine what proteins are under control of the GATA-2 -77 enhancer in a pool of heterogeneous blood progenitor cells with the specific focus on Socs2 expression.

HDAC Inhibitors Impair GATA-3 DNA Binding and Target Gene Expression in T-cell Neoplasms

Project description:To investigate early transcriptional changes upon HDACi treatment, a well characterized and p53-deficient CTCL cell line (H9) and primary malignant T cells isolated from the peripheral blood of Sezary Syndrome (SS) patients (n=3) were cultured for 6 hours in the presence of vehicle control, romidepsin (romi) or belinostat (beli) and transcriptionally profiled by RNA-seq

ChIP seq for GATA-1 and HDAC1 in G1E cells with wild type GATA-1 or mutant

Project description:The transcription factor GATA-1 is essential for erythroid and megakaryocytic cell differentiation and maturation. Previous reports show that GATA-1 is modulated through acetylation modification and through FOG-1 mediated indirect intereaction with HDAC1/2 containing NuRD corepressor complexes. In this study, we found that NuRD does not deacetylate GATA-1. However, HDAC1 alone can efficiently deacetylates GATA-1 and the direct interaction of HDAC1 and GATA-1 is required for the deacetylation. Two arginines within GATA-1 linker region are important for this interaction and arginine to alanine mutations (2RA mutant) largely reduces GATA-1 binding to HDAC1 in FOG-1 independent manner. GATA-1 2RA mutant were then introduced into G1E cells, a GATA-1-null erythroid progenitor cells. The 2RA mutant is acetylated but fails to induce erythroid differentiation. Gene expression analysis shows that GATA-1 2RA mutant affects GATA-1 function in both GATA-1 activated and repressed genes. The gene expression pattern partially overlap with gene expression profile of GATA-1V205M, a GATA-1 mutant with defective FOG-1 binding. ChIP-seq analysis further reveal that 2RA mutation largely reduced GATA-1 chromatin binding, most profoundly at gene promoter regions. HDAC1 recruitment on those promoters are also strongly reduced. These results revealed that GATA-1 recruits HDAC1 to GATA-1 regulated gene promoters and HDAC1 is required for GATA-1 mediated transcription regulation.
