Combined mutation of C/EBPa and GATA-2 induce bi-lineage acute erythroid leukemia through transformation of a neomorphic neutrophil-erythroid progenitor [ATAC-seq]

Project description:Acute erythroid leukemia (AEL) most commonly involves transformation of both the myeloid and erythroid lineages. However, the mutations that cause AEL and the nature of the transformed cell that sustains the bi-lineage leukemia phenotype remain unknown. We here show that combined bi-alleCD45.2+LKFcgRII/III+CD55- C/EBPa and GATA-2 zinc finger 1 (ZnF1) mutations are sufficient to induce bi-lineage AEL, and that the leukemia-initiating cell has a Lin–Sca-1–c-Kit+CD150–FcyRII/III+ surface phenotype, consistent with a committed myeloid progenitor. However, we find that in the presence of bi-alleCD45.2+LKFcgRII/III+CD55- C/EBPa mutation this cell population acquires ectopic erythroid gene expression and lineage potential, leading to the formation of neomorphic neutrophil-erythroid lineage progenitors, which upon transformation generate the bi-lineage leukemia-initiating cell. These results identify C/EBPa and GATA-2 ZnF1 mutations as causative of AEL, and demonstrate that transcriptional reprogramming by a leukemia-initiating mutation can re-define the lineage output of the resulting leukemia-initiating cells.

GATA-1-regulated erythroid microRNAs

Project description:We employed a gene complementation strategy combined with microarray screening to identify miRNAs involved in the formation of erythroid (red blood) cells. To search for GATA-1-regulated erythroid miRNAs, we used the Gata-1– erythroblast line G1E. These cells proliferate in culture as immature erythroid precursors and undergo terminal maturation when GATA-1 activity is restored. G1E-ER4 is a sub-line stably expressing an estrogen-activated form of GATA-1 (GATA-1 fused to the ligand binding domain of the estrogen receptor). Treatment of G1E-ER4 cells with estradiol induces a GATA-1-regulated program of gene expression with concomitant cellular maturation. We used a microarray to evaluate the expression of 292 different miRNAs in G1E-ER4 cells at 0 versus 24 hours after GATA-1 activation. Affymetrix gene expression profiling has previously been deposited (GEO accession no. GSE628). Keywords: microRNA analysis of a cell-line model of erythroid maturation

GATA-1 and heme regulate the erythroid cell transcriptome.

Project description:Alas2 gene encodes the rate-limiting enzyme in heme biosynthesis. CRISPR/Cas9-mediated ablation of two Alas2 intronic cis-elements strongly reduced GATA-1-induced Alas2 transcription, heme biosynthesis, and GATA-1 regulation of other vital constituents of the erythroid cell transcriptome. Bypassing Alas2 function in Alas2 cis-element-mutant (double mutant) cells by providing its catalytic product 5-aminolevulinic acid (5-ALA) rescued heme biosynthesis and the GATA-1-dependent genetic network. We discovered a GATA factor- and heme-dependent circuit that establishes the erythroid cell transcriptome.
