Project description:Methylation of histone 3 lysine 36 (H3K36me) has emerged as an essential epigenetic component for the faithful regulation of gene expression. Despite its importance in development, disease, and cancer, how the molecular agents collectively shape the genome-wide deposition of H3K36me is unclear. Here, we use mouse mesenchymal stem cells to comprehensively perturb the components of the H3K36me deposition machinery and infer the activities of the five most prominent players: SETD2, NSD1, NSD2, NSD3, and ASH1L. We find that H3K36me2 is the most abundant of the three methylation states and that it is predominantly deposited at intergenic regions by NSD1, and in part by NSD2. In contrast, H3K36me1/3 are most abundant within exons and are positively correlated with gene expression. We demonstrate that while SETD2 is responsible for depositing most H3K36me3, it also deposits H3K36me2 within transcribed genes. Additionally, loss of SETD2 results in an increase of exonic H3K36me1, suggesting that other H3K36 methyltransferases may prime gene bodies with lower methylation states ahead of transcription. Through a reductive approach, we uncover the distribution patterns of NSD3- and ASH1L-catalyzed H3K36me2. While NSD1/2 establish broad intergenic H3K36me2 domains, NSD3 deposits H3K36me2 peaks centered on active promoter and enhancer regions. Meanwhile, the activity of ASH1L is restricted to regulatory elements of developmentally relevant genes, and our analyses implicate PBX2 as a potential recruitment factor. Overall, our study provides new insights into the regulation of H3K36me and helps to consolidate the wealth of previous observations in the context of structured analyses.

In contrast, H3K36me1/3 are most abundant within exons and have a positive correlation with gene expression. We further demonstrate that while SETD2 is responsible for depositing most H3K36me3, it also deposits a modest amount of H3K36me2 within transcribed genes. Additionally, loss of SETD2 results in an increase of exonic H3K36me1, suggesting that other H3K36 methyltransferases may prime gene bodies with lower methylation states ahead of transcription. Through a reductive approach, we uncover the genome-wide distribution patterns of NSD3- and ASH1L-catalyzed H3K36me2. While NSD1/2 establish broad intergenic H3K36me2 domains, NSD3 deposits broad H3K36me2 peaks centered on active promoter and enhancer regions. Meanwhile, the activity of ASH1L is focused primarily on the promoters of developmentally relevant genes, and our analyses implicate PBX2 as a potential recruitment factor for ASH1L to these regions. Overall, our study provides new insights into the regulation of H3K36me by the H3K36 methyltransferase family and helps to consolidate the wealth of previous observations in the context of a structured analysis.

Project description:BackgroundMethylation of histone 3 lysine 36 (H3K36me) has emerged as an essential epigenetic component for the faithful regulation of gene expression. Despite its importance in development and disease, how the molecular agents collectively shape the H3K36me landscape is unclear.ResultsWe use mouse mesenchymal stem cells to perturb the H3K36me methyltransferases (K36MTs) and infer the activities of the five most prominent enzymes: SETD2, NSD1, NSD2, NSD3, and ASH1L. We find that H3K36me2 is the most abundant of the three methylation states and is predominantly deposited at intergenic regions by NSD1, and partly by NSD2. In contrast, H3K36me1/3 are most abundant within exons and are positively correlated with gene expression. We demonstrate that while SETD2 deposits most H3K36me3, it may also deposit H3K36me2 within transcribed genes. Additionally, loss of SETD2 results in an increase of exonic H3K36me1, suggesting other (K36MTs) prime gene bodies with lower methylation states ahead of transcription. While NSD1/2 establish broad intergenic H3K36me2 domains, NSD3 deposits H3K36me2 peaks on active promoters and enhancers. Meanwhile, the activity of ASH1L is restricted to the regulatory elements of developmentally relevant genes, and our analyses implicate PBX2 as a potential recruitment factor.ConclusionsWithin genes, SETD2 primarily deposits H3K36me3, while the other K36MTs deposit H3K36me1/2 independently of SETD2 activity. For the deposition of H3K36me1/2, we find a hierarchy of K36MT activities where NSD1 > NSD2 > NSD3 > ASH1L. While NSD1 and NSD2 are responsible for most genome-wide propagation of H3K36me2, the activities of NSD3 and ASH1L are confined to active regulatory elements.

Project description:Nuclear receptor-binding SET domain protein 1 (NSD1) prototype is a family of mammalian histone methyltransferases (NSD1, NSD2/MMSET/WHSC1, NSD3/WHSC1L1) that are essential in development and are mutated in human acute myeloid leukemia (AML), overgrowth syndromes, multiple myeloma and lung cancers. In AML, the recurring t(5;11)(q35;p15.5) translocation fuses NSD1 to nucleoporin-98 (NUP98). Here, we present the first characterization of the transforming properties and molecular mechanisms of NUP98-NSD1. We demonstrate that NUP98-NSD1 induces AML in vivo, sustains self-renewal of myeloid stem cells in vitro, and enforces expression of the HoxA7, HoxA9, HoxA10 and Meis1 proto-oncogenes. Mechanistically, NUP98-NSD1 binds genomic elements adjacent to HoxA7 and HoxA9, maintains histone H3 Lys 36 (H3K36) methylation and histone acetylation, and prevents EZH2-mediated transcriptional repression of the Hox-A locus during differentiation. Deletion of the NUP98 FG-repeat domain, or mutations in NSD1 that inactivate the H3K36 methyltransferase activity or that prevent binding of NUP98-NSD1 to the Hox-A locus precluded both Hox-A gene activation and myeloid progenitor immortalization. We propose that NUP98-NSD1 prevents EZH2-mediated repression of Hox-A locus genes by colocalizing H3K36 methylation and histone acetylation at regulatory DNA elements. This report is the first to link deregulated H3K36 methylation to tumorigenesis and to link NSD1 to transcriptional regulation of the Hox-A locus. Experiment Overall Design: Total RNA was extracted from stably transformed progenitors cultured in vitro and the expression levels of mRNA transcripts quantified using the Affymetrix GeneChip Mouse Genome 430 2.0 array, as previously described. The GEO database accession numbers: for progenitors immortalized by HoxA9 (GSM190542, GSM190546, GSM190547); for progenitors immortalized by coexpressed HoxA9 plus Meis1 (GSM190548, GSM190549, GSM190550); for progenitors immortalized by NUP98-NSD1 (GSM190551, GSM190552, GSM190553); and for progenitors immortalized by MLL-ENL (GSM190554). Experiment Overall Design: NOTE: CEL files and dChip data were requested by GEO but not provided.

Project description:SETD2 is the sole epigenetic factor responsible for catalyzing histone 3, lysine 36, tri-methylation (H3K36me3) in mammals. Its role in regulating diverse cellular processes such as RNA splicing, DNA repair, and spurious transcription underlie its broader tumor suppressor function, which has been detailed in a multitude of cancer types. SETD2 mutation, and by extension loss of H3K36me3, promotes the epithelial-mesenchymal transition (EMT) and is clinically associated with adverse outcomes highlighting a therapeutic need to develop targeted therapies against this dangerous mutation. To this end we employed an unbiased genome-wide synthetic lethal screen, which identified another H3K36me writer, NSD1, as a synthetic lethal modifier in SETD2-mutant cells. Confirmation of this synthetic lethal interaction was performed via modeling in isogenic clear cell renal cell carcinoma (ccRCC ) cell lines. Depletion of NSD1 using a CRISPRi targeting approach promoted the loss of SETD2-mutant cells coincident with elevated DNA damage and apoptosis. Surprisingly, only suppression of NSD1, and not the related H3K36-methyltransferases NSD2 or NSD3, promoted synthetic lethality (SL) in these models. Further investigation of H3K36me2 targeting by NSD1 and NSD2 respectively highlight the independent functions of these epigenetic writers. Furthermore, as a proof-of-principle we demonstrate the therapeutic feasibility of targeting this synthetic lethal interaction by recapitulating the phenotype using a first-of-its kind pharmacologic inhibitor against NSD1 (BT5). Notably, these findings unify unbiased genome-wide screening approaches with the latest genetic and pharmacologic modeling methodologies to reveal an entirely novel epigenetic approach in the advancement of individualized therapies for the treatment of SETD2-mutant cancer.

Project description:NSD1, NSD2, and NSD3 constitute the nuclear receptor-binding SET Domain (NSD) family of histone 3 lysine 36 (H3K36) methyltransferases. These structurally similar enzymes mono- and di-methylate H3K36, which contribute to the maintenance of chromatin integrity and regulate the expression of genes that control cell division, apoptosis, DNA repair, and epithelial-mesenchymal transition (EMT). Aberrant expression or mutation of members of the NSD family is associated with developmental defects and the occurrence of some types of cancer. In this review, we discuss the effect of alterations in NSDs on cancer patient's prognosis and response to treatment. We summarize the current understanding of the biological functions of NSD proteins, focusing on their activities and the role in the formation and progression in solid tumors biology, as well as how it depends on tumor etiologies. This review also discusses ongoing efforts to develop NSD inhibitors as a promising new class of cancer therapeutic agents.

Project description:BackgroundHistone lysine methylation has a pivotal role in regulating the chromatin. Histone modifiers, including histone methyl transferases (HMTases), have clear roles in human carcinogenesis but the extent of their functions and regulation are not well understood. The NSD family of HMTases comprised of three members (NSD1, NSD2/MMSET/WHSC1, and NSD3/WHSC1L) are oncogenes aberrantly expressed in several cancers, suggesting their potential to serve as novel therapeutic targets. However, the substrate specificity of the NSDs and the molecular mechanism of histones H3 and H4 recognition and methylation have not yet been established.ResultsHerein, we investigated the in vitro mechanisms of histones H3 and H4 recognition and modifications by the catalytic domain of NSD family members. In this study, we quantified in vitro mono-, di- and tri- methylations on H3K4, H3K9, H3K27, H3K36, H3K79, and H4K20 by the carboxyl terminal domain (CTD) of NSD1, NSD2 and NSD3, using histone as substrate. Next, we used a molecular modelling approach and docked 6-mer peptides H3K4 a.a. 1-7; H3K9 a.a. 5-11; H3K27 a.a. 23-29; H3K36 a.a. 32-38; H3K79 a.a. 75-81; H4K20 a.a. 16-22 with the catalytic domain of the NSDs to provide insight into lysine-marks recognition and methylation on histones H3 and H4.ConclusionsOur data highlight the versatility of NSD1, NSD2, and NSD3 for recognizing and methylating several histone lysine marks on histones H3 and H4. Our work provides a basis to design selective and specific NSDs inhibitors. We discuss the relevance of our findings for the development of NSD inhibitors amenable for novel chemotherapies.
