Role of the histone demethylase KDM2B in hematopoietic homeostasis and malignancies [human cell line gene expression]

ABSTRACT: Development of the hematopoietic system is dynamically controlled by the interplay of transcriptional and epigenetic networks to determine cellular identity. Those networks are critical for homeostasis and frequently dysregulated in leukemias. We identified histone demethylase Kdm2b as a critical regulator of definitive hematopoiesis and lineage specification of hematopoietic stem and progenitor cells (HSPCs). RNA sequencing in murine HSPCs and genome-wide chromatin immunoprecipitation studies in human leukemias revealed that Kdm2b regulates differentiation, lineage choice, cytokine signaling, and quiescence.

ZNF384 fusion oncoproteins drive lineage aberrancy in acute leukemia

Project description:ZNF384-rearranged fusion oncoproteins (FO) define a subset of lineage ambiguous leukemias, but the mechanistic role of ZNF384 FO in leukemogenesis and lineage ambiguity is poorly understood. Here, using viral expression in mouse and human hematopoietic stem and progenitor cells (HSPCs) and a Ep300-Zfp384 mouse model we show that ZNF384 FO promote hematopoietic expansion, myeloid lineage skewing, and self-renewal. In mouse HSPCs, concomitant lesions such as NRASG12D, were required for fully penetrant leukemia, whereas expression of ZNF384 FO drove development of B/myeloid leukemia in human HSPCs, with sensitivity of human ZNF384r leukemia to FLT3 inhibition in vivo. Mechanistically, ZNF384 FO occupy a subset of predominantly intragenic/enhancer regions with increased histone 3 lysine acetylation suggesting enhancer function. These data define a paradigm for FO-driven lineage ambiguous leukemia, in which expression in HSPCs results in deregulation of lineage-specific genes and hematopoietic skewing, progressing to full leukemic transformation in the presence of proliferative stress.

Kdm2b maintains murine embryonic stem cell status by recruiting PRC1 complex to CpG islands of lineage genes [ChIP-Seq]

Project description:Polycomb group (PcG) proteins play important roles in repressing lineage-specific genes and maintaining the undifferentiated state of mouse embryonic stem cells (mESCs). However, the mechanisms by which PcG proteins are recruited to their targets are largely unknown. Here, we show that the histone demethylase Kdm2b is highly expressed in mESCs and regulated by the pluripotent factors Oct4/Sox2 directly. Depletion of Kdm2b in mESCs causes de-repression of lineage-specific genes and induces early differentiation. The function of Kdm2b depends on its CXXC-ZF domain, which mediates Kdm2b’s genome-wide binding to CpG islands (CGIs). Kdm2b interacts with the core components of the Polycomb repressive complex 1 (PRC1) and recruits the complex to the CGIs of early lineage-specific genes. Thus, our study not only reveals a novel Oct4/Sox2-Kdm2b-PRC1-CGI regulatory axis and its function in maintaining undifferentiated state of mESCs, but also demonstrates a critical function of Kdm2b in recruiting PRC1 to the CGIs of lineage-specific genes to repress their expression. In this dataset, we include the ChIP-seq data of Kdm2b, Ezh2 and Ring1b in both control and Kdm2b knock down mouse embryonbic stem cells.
