UTX-mediated enhancer and chromatin remodeling suppresses myeloid leukemogenesis through noncatalytic inverse regulation of ETS and GATA programs

Project description:The histone H3 Lys27-specific demethylase UTX (or KDM6A) is targeted by loss-of-function mutations in multiple cancers. Here, we demonstrate that UTX suppresses myeloid leukemogenesis through noncatalytic functions, a property shared with its catalytically inactive Y-chromosome paralog, UTY (or KDM6C). In keeping with this, we demonstrate concomitant loss/mutation of KDM6A (UTX) and UTY in multiple human cancers. Mechanistically, global genomic profiling showed only minor changes in H3K27me3 but significant and bidirectional alterations in H3K27ac and chromatin accessibility; a predominant loss of H3K4me1 modifications; alterations in ETS and GATA-factor binding; and altered gene expression after Utx loss. By integrating proteomic and genomic analyses, we link these changes to UTX regulation of ATP-dependent chromatin remodeling, coordination of the COMPASS complex and enhanced pioneering activity of ETS factors during evolution to AML. Collectively, our findings identify a dual role for UTX in suppressing acute myeloid leukemia via repression of oncogenic ETS and upregulation of tumor-suppressive GATA programs.

UTX-mediated chromatin remodeling suppresses myeloid leukaemogenesis through non-catalytic inverse regulation of ETS and GATA transcriptional programs (ATAC-Seq)

Project description:The H3K27 lysine-specific demethylase UTX is targeted by loss-of-function mutations in multiple cancers. Here, we demonstrate that UTX suppresses myeloid leukaemogenesis through non-catalytic functions, a property it shares with its catalytically inactive Y-chromosome paralogue, UTY. In keeping with this, we demonstrate concomitant loss/mutation of UTX and UTY in multiple human cancers. Mechanistically, global genomic profiling revealed only minor changes in H3K27Me3, but significant and bidirectional alterations of H3K27Ac and chromatin accessibility, alterations in ETS and GATA factor binding and altered gene expression upon Utx loss. By integrating proteomic and genomic analyses, we link these changes to UTX coordination of ATP-dependent chromatin remodelling and competition between UTX and ETS factors for binding at critical DNA-sequences. Collectively, our findings reveal a dual role for UTX in suppressing acute myeloid leukaemia via inhibition of oncogenic ETS and upregulation of tumour-suppressive GATA programmes. We propose that equivalent changes in tissue-specific oncogenic and tumour-suppressive transcriptional programmes operate in other UTX-mutated cancers.

HNF1A, UTX, H3K27me3 and H3K27ac ChIP-seq in wild-type and UTX- or HNF1A-deficient mouse pancreas

Project description:HNF1A and UTX are putative tumor suppressors in pancreatic cancer. In this study, we have combined mouse genetics, transcriptomics and genome binding studies to link HNF1A and UTX in a molecular mechanism that suppresses pancreatic cancer. In this session, we have profiled UTX, HNF1A, H3K27me3 and H3K27ac in normal and UTX- or HNF1A-deficient mouse pancreas by ChIP-seq experiments. We show that HNF1A recruits UTX to its genomic targets in pancreatic acinar cells, which results in remodeling of the chromatin landscape and activation of a broad transcriptional program of differentiated acinar cells, which in turn indirectly suppresses tumor suppressor pathways.

RNA-seq of wild-type and Utx- or Hnf1a-deficient mouse pancreas

Project description:HNF1A and UTX are putative tumor suppressors in pancreatic cancer. In this study, we have combined mouse genetics, transcriptomics and genome binding studies to link HNF1A and UTX in a molecular mechanism that suppresses pancreatic cancer. In this session, we have determined the transcriptome of HNF1A and UTX in the exocrine pancreas. We show that HNF1A recruits UTX to its genomic targets in pancreatic acinar cells, which results in remodeling of the chromatin landscape and activation of a broad transcriptional program of differentiated acinar cells, which in turn indirectly suppresses tumor suppressor pathways.

Mus musculus Gata2 +9.5 Ets C>T transition untreated and 10 days post 5-FU LSK cells

Project description:The development and function of stem and progenitor cells that produce blood cells are vital in physiology. GATA2 mutations cause immunodeficiency, myelodysplastic syndrome (MDS) and acute myeloid leukemia (AML). GATA-2 physiological activities necessitate that it be strictly regulated and cell type-specific enhancers fulfill this role. The +9.5 intronic enhancer harbors multiple conserved cis-elements, and germline mutations of these cis-elements are pathogenic in humans. Since mechanisms underlying how GATA2 enhancer disease mutations impact hematopoiesis and pathology are unclear, we generated mouse models of the enhancer mutations. While a multi-motif mutant was embryonic lethal, a single-nucleotide Ets motif mutant was viable and steady-state hematopoiesis was normal. However, the Ets motif mutation abrogated stem/progenitor cell regeneration following stress. These results reveal a new mechanism in human genetics in which a disease mutation inactivates enhancer regenerative activity, while sparing developmental activity. Mutational sensitization to stress that instigates hematopoietic failure constitutes a paradigm for GATA-2-dependent pathogenesis.
