Genome-wide analysis of H3.3, H3K36me2, H3K36me3 and ZMYND11 accumulation in WT MEFs and NSD2 KO MEFs.

Project description:We found that the incorporation of histone H3 variant H3.3 was impaired and the accumulation of ZMYND11, which specifically binds to H3.3K36me3, was decreased in NSD2 KO MEFs. About H3K36me2, the average gene body profiles of H3K36me2 showed preferential enrichment of H3K36me2 at the promoter and first half of the genic regions. We examined H3K36me2 mark in super enhancer regions using the ROSE super enhancer prediction program and identified of the 519 super enhancer islands of H3K36me2 in WT MEFs the H3K36me2 signals were decreased in NSD2 KO MEFs

Genome-wide mRNA expression profiling of WT MEFs and NSD2 KO MEFs

Project description:NSD2 (also known as Whsc1, MMSET) play a role in H3K36 methyl transferase. Here we showed that 199 ISGs of the total 393 ISGs after 2h IFN treatment were up regulated in NSD2 KO MEFs, suggesting negatively regulate ISGs induction. IFN pretreatment creates transcriptional memory. In this study we identified 129 ISGs were memory ISGs and 40 ISGs were non-memory ISGs.

Genome-wide mRNA expression profiling of ZMYND11 crispr KO in NIH3T3 cells upon IFN treatment.

Project description:ZMYND11 is a ‘reader’ protein, which specifically recognizes H3.3K36me3 and regulate RNA polymerase II elongation. Our RNA-seq data showed that 93 ISGs were up regulated, 47 ISGs were down regulated and 48 ISGs were not changed in ZMYND11 KO.

Stable over expression of the SPOP-substrate ZMYND11 in VCaP cells

Project description:SPOP is known to bind to serine/theronine-rich degrons on substrate proteins. We identified two degron sequences within the PWWP and MYND domain of ZMYND11, a novel SPOP substrate, and investigated whether ZMYND11 may contribute to the transcriptional output of mutant SPOP in VCaP cancer cells. Hence, we performed over-expression of degron-deficient ZMYND11 and degron-deficient ZMYND11 with W294A mutation in VCaP cells. While WT ZMYND11 constructs can be robustly over-expressed at the mRNA level, only the degron-deficient variants yielded a robost increase in ZMYND11 protein expression. Degron mutant-induced transcriptional perturbations partially mimicked SPOP mutant-induced gene expression changes, suggesting that ZMYND11 is sufficient to recapitulate certain features of mutant SPOP.

Defining the NSD2 interactome: PARP1 PARylation reduces NSD2 histone methyltransferase activity and impedes chromatin binding

Project description:NSD2 is a histone methyltransferase that specifically dimethylates histone H3 lysine 36 (H3K36me2), a modification associated with gene activation. Dramatic overexpression of NSD2 in t(4;14) multiple myeloma (MM) and an activating mutation of NSD2 discovered in acute lymphoblastic leukemia (ALL) are significantly associated with altered gene activation, transcription and DNA damage repair. The partner proteins through which NSD2 may influence critical cellular processes remain poorly defined. In this study, we utilized proximity-based labelling (BioID) combined with label-free quantitative mass spectrometry to identify high confidence NSD2 interacting partners in MM cells.

Proteosomal degradation of NSD2 by BRCA1 promotes leukemia cell differentiation

Project description:Inhibiton of NSD2 by shRNA induces K562 differentiation via increasing erythroid specfic lineage factors The human myelogenous leukemic cell line, K562 undergoes erythroid differentiation by exposure to hemin. Here, we uncovered NSD2 as an innate erythroid differentiation-related factor through the genome-wide CRISPR library screening and explored the regulatory role of NSD2 during myeloid leukemia cell differentiation. We found that NSD2 stability was disrupted by poly-ubiquitination in differentiated K562 cells. Proteomic analysis revealed interaction between NSD2 and an E3 ubiquitin ligase, BRCA1 which ubiquitylates NSD K292 residue. Depletion of BRCA1 stabilized NSD2 protein and suppressed K562 cell differentiation. Furthermore, BRCA1 protein level was decreased in bone marrow tumor, while NSD2 level was elevated. Surprisingly, among BRCA1 mutation(s) discovered in lymphoma patients, BRCA1 K1183R prevented its translocation into the nucleus and did not reduce NSD2 protein level in hemin-treated K562 cells and eventually disrupted cell differentiation. Our results indicated that regulation of NSD2 stability by BRCA1-mediated ubiquitination as a potential therapeutic target process in multiple myeloma.

NSD2 links dimethylation of histone H3 at lysine 36 to oncogenic programming [RNAi]

Project description:NSD2 (also named MMSET and WHSC1) is a histone lysine methyltransferase that is implicated in diverse diseases and commonly overexpressed in multiple myeloma due to a recurrent t(4;14) chromosomal translocation. However, the precise catalytic activity of NSD2 is obscure, preventing progress in understanding how this enzyme influences chromatin biology and myeloma pathogenesis. Here we show that dimethylation of histone H3 at lysine 36 (H3K36me2) is the principal chromatin-regulatory activity of NSD2. Catalysis of H3K36me2 by NSD2 is sufficient for gene activation. In t(4;14)-positive myeloma cells, the normal genome-wide and gene-specific distribution of H3K36me2 is obliterated, creating a chromatin landscape that selects for a transcription profile favorable for myelomagenesis. Catalytically active NSD2 confers xenograft tumor formation and invasion capacity upon t(4;14)-negative cells and NSD2 promotes oncogenic transformation of primary cells in an H3K36me2-dependent manner. Together our findings establish H3K36me2 as the primary product generated by NSD2, and demonstrate that genomic disorganization of this canonical chromatin mark initiates oncogenic programming. Genome-wide expression profiling of KMS11 cells stably transduced with control vector in comparison to two independent shRNAs against NSD2. Each cell line is tested in duplicate.
