Genome wide localization of chromatin bound NUP98-PHF23 (NP23)

Genome wide localization of chromatin bound NUP98-PHF23 (NP23)

Project description:We analyzed the genome wide localization of H3K4me3, H3K27me3 and the NUP98-PHF23 (with V5 tag) fusion protein which binds H3K4me3 via its PHD finger, using ChIP-seq. Results correlated with gene expression profiles. NUP98-PHF23 bound only 1.6% of H3K4me3 marks including Hoxa/b + Meis1. Assess H3K4me3 and H3K27me3 histone marks, and correlate these marks with chromatin binding of the NP23 fusion protein using lymphoblast and myeloblast cell lines derived from NP23 leukemias.

Mechanistic insights into chromatin targeting by leukemic NUP98-PHF23 fusion

Project description:The dysregulation of plant homeodomain (PHD) fingers has been implicated in several human diseases, including cancer. In a subset of aggressive acute myeloid leukemia (AML), chromosomal translocations that involve nucleoporin 98 (NUP98), a component of the nuclear pore complex, and a PHD finger-containing protein, such as KDM5A/JARID1A, PHF23 and BPTF, generate potent oncoproteins (namely NUP98-KDM5A, NUP98-PHF23 and NUP98-BPTF; or together termed as NUP98-PHD fusions) that are able to arrest hematopoietic differentiation and induce acute myeloid leukemia in murine models. In these processes, a PHD finger that specifically recognizes H3K4me3/2 marks was essential for leukemogenesis. Mutations in PHD fingers that abrogated H3K4me3 binding also abolished leukemic transformation. An overlap of NUP98-KDM5A oncoprotein binding sites and H3K4me3-positive loci at the Hoxa/b gene clusters and Meis1 in ChIP-seq together with NMR analysis of the H3K4me3-binding sites of the PHD fingers from PHF23, KDM5A and BPTF suggests a common PHD finger-dependent mechanism that promotes leukemogenesis by this type of NUP98-PHD finger fusions. Disulfiram (DS), a small molecule compound that directly targets the PHD finger, shows anti-proliferation effects in AML cells expressing NUP98-PHD through the conserved inhibitory mechanism. Our findings highlight the direct correlation between the abilities of NUP98-PHD finger fusion chimeras to associate with H3K4me3-enriched chromatin and leukemic transformation.

Gene expression study of leukemic and premalignant hematopoietic tissues from NUP98-PHF23 (NP23) mice.

Project description:NUP98-PHF23 is oncogenic and results in a Hoxa/b + Meis1 overexpression in NP23 leukemias and in premalignant (clinically healthy) hematopoietic tissues. Gene expression profiles from AML, pre-T LBL and B-ALL were compared to wild type bone marrow, thymus and spleen tissues respectively. Similarly, gene expression profiles from premalignant (clinically healthy) NP23 bone marrow, thymus and spleen were compared to wild type bone marrow, thymus and spleen tissues respectively. 106A and 748T lymphoblastic cell lines were compared to wild type thymic tissue.

An epigenetic mechanism underlying chromosome 17p deletion-driven tumorigenesis

Project description:Chromosome copy number variations are a hallmark of human cancers and among them chromosome 17p loss is the most common one and associated with poor prognosis. Our previous work demonstrates that 17p deletions can promote tumorigenesis more than p53 loss. Herein, with multiple functional genetic strategies, we identify a new 17p tumor suppressor, PHD finger protein 23 (PHF23). PHF23 deficiency impaires B cell differentiation and promotes Myc-driven lymphoma. Mechanistically, PHF23, a H3K4me3 reader, directly binds and represses the deacetylation activity of the SIN3-HDAC complex through its N-terminus, which coordinates two major active histone markers H3K4me3 and H3K27ac for activation of downstream B cell-differentiation genes and tumor suppressors. Further, we show that dysregulation of the PHF23-SIN3-HDAC complex is essential for PHF23 deficiency-induced tumorigenesis and maintenance. Hence, our study reveals a novel epigenetic regulatory mechanism that contributed to the pathology of 17p deleted cancers and suggests novel susceptibility of this miserable disease.
