Project description:Cellular binary fate decisions require the progeny to silence genes associated with the alternative fate. The major subsets of alpha:beta T cells have been extensively studied as a model system for fate decisions. While the transcription factor RUNX3 is required for the initiation of Cd4 silencing in CD8 T cell progenitors, it is not required to maintain the silencing of Cd4 and other helper T lineage genes. The other runt domain containing protein, RUNX1, silences Cd4 in an earlier T cell progenitor, but this silencing is reversed whereas the gene silencing after RUNX3 expression is not reverse. Therefore, we hypothesized that RUNX3 and not RUNX1 recruits other factors that maintains the silencing of helper T lineage genes in CD8 T cells. To this end, we performed a proteomics screen of RUNX1 and RUNX3 to determine candidate silencing factors.

Project description:The t(8;21) translocation fuses the DNA binding domain of the hematopoietic master regulator RUNX1 to the ETO protein. The resultant RUNX1/ETO fusion protein is a leukemia-initiating transcription factor that interferes with RUNX1 function. The result of this interference is a block in differentiation and, finally, the development of acute myeloid leukemia (AML). To obtain insights into RUNX1/ETO-dependant alterations of the epigenetic landscape we measured genome-wide RUNX1- and RUNX1/ETO bound regions in t(8;21) cells and assessed to what extent the effects of RUNX1/ETO on the epigenome depend on its continued expression in established leukemic cells. To this end we determined dynamic alterations of histone acetylation, RNA Polymerase II binding and RUNX1 occupancy in the presence or absence of RUNX1/ETO using a knockdown approach. Combined global assessments of chromatin accessibility and kinetic gene expression data show that RUNX1/ETO controls the expression of important regulators of hematopoietic differentiation and self-renewal. We show that selective removal of RUNX1/ETO leads to a widespread reversal of epigenetic reprogramming and a genome-wide re-distribution of RUNX1 binding, resulting in the inhibition of leukemic proliferation and self-renewal and the induction of differentiation. This demonstrates that RUNX1/ETO represents a pivotal therapeutic target in AML.

Project description:A critical problem in biology is understanding how cells choose between self-renewal and differentiation. To generate a comprehensive view of the mechanisms controlling early hematopoietic precursor self-renewal and differentiation, we used systems-based approaches and murine EML multipotential hematopoietic precursor cells as a primary model. EML cells give rise to a mixture of self-renewing Lin-SCA+CD34+ cells and partially differentiated non-renewing Lin-SCA-CD34- cells in a cell autonomous fashion. We identified and validated the HMG box protein TCF7 as a key regulator in this self-renewal/differentiation switch, and it operates in the absence of canonical Wnt signaling. We found that TCF7 is the most downregulated transcription factor when CD34+ cells switch into CD34- cells using RNA-Seq. We subsequently identified the target genes bound by TCF7 using ChIP-Seq. We show that TCF7 binds to Runx1 (Aml1) promoter region, and RUNX1 and TCF7 co-regulate. Gene Set Enrichment Analysis suggests that TCF7 primarily acts as a positive regulator of genes preferentially expressed in CD34+ cells. Consistent with this possibility, knocking-down TCF7 represses many up-regulated genes in Lin-CD34+ cells. Finally a network of up-regulated transcription factors of CD34+ cells which defines the self-renewing state was constructed. These studies in EML cells demonstrate fundamental cell-intrinsic properties of the switch between self-renewal and differentiation, and yield valuable insights for manipulating HSCs and other differentiating systems. Examining the transcription factor binding targets of TCF7 and RUNX1.

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.
