ChIP-seq in the cell line NALM-6 for RUNX1 and ETV6-RUNX1 to assess competition between the two proteins for DNA binding

ABSTRACT: RUNX1 and ETV6-RUNX1 possess the same DNA-binding runt domain and are therefore expected to bind to canonical RUNX motifs. As the ETV6-RUNX1 fusion arises in the context of native RUNX1 expression, and since RUNX1 is retained or amplified in B-ALL, the two proteins are likely to compete for the same target sites. To assess this, we performed RUNX1 ChIP-seq in the presence of exogenous ETV6-RUNX1 (or non DNA binding ETV6-RUNX1-R139G) and the reciprocal experiment: ETV6-RUNX1 ChIP (using a V5 tag) in the presence of exogenous RUNX1 or vector control.

Histone H3, lysine 27 acetylation ChIP-seq in NALM6 expressing ETV6-RUNX1

Project description:ETV6-RUNX1 is a fusion protein bringing together almost the entire coding sequence of RUNX1, including the DNA binding runt domain, and the N-terminus of ETV6 which is known to include transcriptional repressors including histone deacetylation 3 (HDAC3). Here we perform ChIP-seq for the active chromatin mark H3K27ac in the NALM6 B-cell acute lymphoblastic leukaemia cell line expressing ETV6-RUNX1 or mutant derivatives of ETV6-RUNX1: Delta helix-loop-helix (dHLH) is a deletion of the pointed domain; R139G is a point mutation in the runt DNA-binding domain.

TEL-AML1 (ETV6-RUNX1) in B-cells and leukemia (part 1)

Project description:We identified directly and indirectly regulated target genes utilizing an inducible TEL-AML1 system derived from the murine pro B-cell line BA/F3 and a monoclonal antibody directed against TEL-AML1. By integration of promoter binding identified with ChIP-on-chip, gene expression and protein output through microarray technology and stable labelling of amino acids in cell culture (SILAC), we identified directly and indirectly regulated targets of the TEL-AML1 fusion protein. Bound promoter regions of immunoprecipitated TEL-AML1 associated genes were first compared to input material and enrichment was calculated. The same was performed for empty vector control cell lines, also treated with the induction reagent mifepriston. Enriched promoter regions were then compared of the both sets. 2 independent replicates each (4 arrays) were performed.

Genome-wide mapping of Runx1-bound sites in early B-cell progenitors

Project description:The t(12;21) chromosomal translocation, targeting the gene encoding the RUNX1 transcription factor, is observed in 25% of pediatric acute lymphoblastic leukemia (ALL) and is an initiating event in the disease. To elucidate the mechanism by which RUNX1 disruption initiates leukemogenesis, we investigated its normal role in murine B-cell development. Gene expression analysis and genome-wide Runx1-occupancy studies support the hypothesis that Runx1 reinforces the transcription factor network in B-cell progenitors governing early B-cell survival and development . ChIP-seq experiments were performed in the proB-cell line BMiFLT3(15-3), stably transduced with the transcription factor Runx1, to identify Runx1-bound sites in early B-cell progenitors.

RNA-seq as a global measure of the similarity between human pluripotent stem cell and fetal liver derived B cell hierarchies

Project description:Evidence suggests childhood acute lymphoblastic leukemia (cALL) arises in early human development. Existing models of pre-leukemic initiation using the ETV6-RUNX1 fusion do not recapitulate human disease, highlighting the need for a developmentally relevant human model system. A human pluripotent stem cell (hPSC) model genome was engineered to express ETV6-RUNX1 from the endogenous ETV6 promoter. RNA-seq data from sorted hematopoietic progenitors identified according to surface markers.
