The aim of the present study was to investigate the use of GATA-3 markers in the detection of hematologic disorders in children. In total, 35 pediatric patients diagnosed with blood disease and treated in Henan Red Cross Blood Center from January 2014 to June 2015 were selected for the observation group. Another 32 healthy children were selected for the control group. The differences in the GAT...

In vertebrates, transcriptional regulators of the GATA family appear to have a conserved function in differentiation and organ development. GATA-1, -2 and -3 are required for different aspects of hematopoiesis, while GATA-4, -5 and -6 are expressed in various organs of endodermal origin, such as intestine and liver, and are implicated in endodermal differentiation. Here we report that the Droso...

GATA-1, mainly expressed during erythroid differentiation, has been shown to regulate the genes specifically expressed in the late stages of erythropoiesis and to protect erythroid cells from apoptosis, suggesting that it might interfere with the cell cycle. By expressing the retrovirally transduced human GATA-1 cDNA in NIH3T3 fibroblasts, we have shown that GATA-1 alone was unable to transacti...

The transcription factor GATA-2 is expressed in hematopoietic stem and progenitor cells and is functionally implicated in their survival and proliferation. In the present study, we show that GATA-2 exists as an acetylated protein in immature precursor cells, KG1. GATA-2 was acetylated in vitro by p300 and GCN5. We have identified multiple acetylation sites by p300 on GATA-2, which include sites...

In agar cultures of marrow cells from adult female BALB/c chimeric GATA-1(Plt13/+) mice, a high frequency of unusual dispersed colonies was noted. Analysis showed that these were colonies of mast cells and that mast cell colony-forming cells (progenitors) could be detected in clonal cultures of adult marrow, neonatal marrow, or fetal liver if the combined stimulus of stem cell factor and interl...

GATA3 belongs to a family of dual zinc finger transcription factors. There are six GATA proteins (GATA 1–6) that share a zinc finger DNA‐binding domain Cys‐X2‐Cys‐X17‐Cys‐X2‐Cys, where X represents any amino acid residue. This domain binds to the consensus motif 5’‐(A/T)GATA(A/G)‐3’. GATA proteins are widely expressed during the development processes of the human cardiovascular, digestive, urog...

GATA family transcription factors play multiple vital roles in hematopoiesis in many cell lineages, and in particular, T cells require GATA-3 for execution of several developmental steps. Transcriptional activation of the Gata3 gene is observed throughout T-cell development and differentiation in a stage-specific fashion. GATA-3 has been described as a master regulator of T-helper 2 (Th2) cell ...

Notch signaling is involved in cell fate decisions in many systems including hematopoiesis. It has been shown that expression of an activated form of Notch1 (aNotch1) in 32D mouse myeloid progenitor cells inhibits the granulocytic differentiation induced by granulocyte colony-stimulating factor (G-CSF). Results of the current study show that aNotch1, when expressed in F5-5 mouse erythroleukemia...
