The NFIA-ETO2 fusion blocks terminal erythroid maturation and induces pure erythroid leukemia (PEL)

ABSTRACT: The NFIA-ETO2 fusion is the product of a t(1;16)(p31;q24) chromosomal translocation so far exclusively found in pediatric patients with pure erythroid leukemia (PEL). To address its role for the pathogenesis of the pure erythroid leukemia, we retrovirally expressed the PEL-associated NFIA-ETO2 fusion in primary erythroblasts in fetal liver-derived erythroblasts from wild-type (C57/B6) mice. To better characterize alteration in chromatin accessibility due to NFIA-ETO2 expression, we analyzed accessible chromatin state by ATAC sequencing from cells kept in 24h in differentiation-inducing medium (DM)

The NFIA-ETO2 fusion blocks terminal erythroid maturation and induces pure erythroid leukemia (PEL) in cooperation with mutant TP53

Project description:The NFIA-ETO2 fusion is the product of a t(1;16)(p31;q24) chromosomal translocation so far exclusively found in pediatric patients with pure erythroid leukemia (PEL). To address its role for the pathogenesis of the pure erythroid leukemia, we retrovirally expressed the PEL-associated NFIA-ETO2 fusion or an in active NFIA-ETOdeltaNHR4 mutant in primary erythroblasts in fetal liver-derived erythroblasts from either wild-type (C57/B6) or TP53R248Q (HUPKI) mice. Gene expression was determined by RNA sequencing from cells kept in maintenance medium (MM) or 24h in differentiation-inducing medium (DM)

Location of NFIA-ETO2 binding site on genome in MEL cells

Project description:The NFIA-ETO2 fusion is the product of a t(1;16)(p31;q24) chromosomal translocation so far exclusively found in pediatric patients with pure erythroid leukemia (PEL). To address its role for the pathogenesis of the pure erythroid leukemia, we retrovirally expressed the PEL-associated NFIA-ETO2 fusion in MEL cells. To better identify direct target gene loci, we sequenced NFIA-ETO2-associated immunoprecipitated chromatin and histone modifications.

Expression data from ETO2 knockdown G1E-ER-GATA-1 cells

Project description:We used microarrays to examine what genes could be regulated by ETO2 in erythroid cells. Comparing expression profile in murine G1E-ER-GATA-1 cells treated with control and ETO2(Cbfa2t3) siRNA on Agilent array. After siRNA transfection, the cells were treated with b-estradiol for 24h to induce GATA-1-mediated erythroid maturation.

Distinct Ldb1/NLI complexes orchestrate γ-globin repression and re-activation through ETO2 in human adult erythroid cells.

Project description:The Ldb1/GATA-1/TAL1/LMO2 complex mediates long range interaction between the β-globin locus control region (LCR) and gene in adult mouse erythroid cells but whether this complex mediates chromatin interactions at other developmental stages or in human cells is unknown. We investigated human NLI (Ldb1 homologue) complex occupancy and chromatin conformation of the β-globin locus in human erythroid cells. In addition to the LCR, we find robust NLI complex occupancy at a site downstream of the Aγ-globin gene, within sequences of BGL3, an intergenic RNA transcript. In cells primarily transcribing β-globin, BGL3 is not transcribed and BGL3 sequences are occupied by NLI core complex members together with co-repressor ETO2 and γ-globin repressor BCL11A. The LCR and β-globin gene establish proximity in these cells. In contrast, when γ-globin transcription is re-activated by cytokines in these cells, ETO2 participation in the NLI complex at BGL3 is diminished, as is BCL11A occupancy, and both BGL3 and γ-globin are transcribed. In these cells, proximity between the BGL3/γ-globin region and the LCR is established. Thus, alternative NLI complexes mediate γ-globin transcription or silencing through long range LCR interactions involving an intergenic site of non-coding RNA transcription and ETO2 is critical to this process.
