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

ABSTRACT: 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.

NUP98-PHF23 is a chromatin-modifying oncoprotein that causes a wide array of leukemias sensitive to inhibition of PHD histone reader function.

In this report, we show that expression of a NUP98-PHF23 (NP23) fusion, associated with acute myeloid leukemia (AML) in humans, leads to myeloid, erythroid, T-cell, and B-cell leukemia in mice. The leukemic and preleukemic tissues display a stem cell-like expression signature, including Hoxa, Hoxb, and Meis1 genes. The PHF23 plant homeodomain (PHD) motif is known to bind to H3K4me3 residues, and chromatin immunoprecipitation experiments demonstrated that the NP23 protein binds to chromatin at a  ...[more]
