Interferon regulatory factor-2 drives megakaryocytic differentiation.
IRFs [IFN (interferon) regulatory factors] constitute a family of transcription factors involved in IFN signalling and in the development and differentiation of the immune system. IRF-2 has generally been described as an antagonist of IRF-1-mediated transcription of IFN and IFN-inducible genes; however, it has been recently identified as a transcriptional activator of some genes, such as those ...
متن کاملDynamics of GATA transcription factor expression during erythroid differentiation.
Although the formation of terminally differentiated erythroid cells has been shown to require the presence of a functional GATA-1 gene in vivo, the role of this transcription factor and other members of the GATA family at earlier stages of erythroid differentiation is unclear. In this report, the expression of GATA-1, GATA-2, and GATA-3 has been examined in enriched peripheral blood progenitors...
متن کاملDifferentiation-specific histone modifications reveal dynamic chromatin interactions and partners for the intestinal transcription factor CDX2.
VIDEO ABSTRACT Cell differentiation requires remodeling of tissue-specific gene loci and activities of key transcriptional regulators, which are recognized for their dominant control over cellular programs. Using epigenomic methods, we characterized enhancer elements specifically modified in differentiating intestinal epithelial cells and found enrichment of transcription factor-binding motifs ...
متن کاملRUNX1 represses the erythroid gene expression program during megakaryocytic differentiation.
The activity of antagonizing transcription factors represents a mechanistic paradigm of bidirectional lineage-fate control during hematopoiesis. At the megakaryocytic/erythroid bifurcation, the cross-antagonism of krueppel-like factor 1 (KLF1) and friend leukemia integration 1 (FLI1) has such a decisive role. However, how this antagonism is resolved during lineage specification is poorly unders...
متن کاملKey Regulatory Gene Expression in Erythroleukemia Differentiation
The characteristics of cellular and molecular mechanisms associated with cell proliferation and differentiation is important to understand malignancy. In this report we characterise a leukemic model, D5A1, to study the action of differentiation agent, cellular events and gene expression of the selected transcription factors. Cells induced with 4 mM hexamethylene bisacetamide (HMBA) caused signs...
