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

Project description:Recognition of modified histones by “reader” proteins plays a critical role in the regulation of transcription1. H3K36 trimethylation (H3K36me3) is deposited onto the nucleosomes in the transcribed regions following RNA polymerase II (Pol II) elongation. In yeast, this mark in turn recruits epigenetic regulators to reset the chromatin at an appropriate state to suppress cryptic transcription2,3. However, much less is known about the role of H3K36me3 in transcription regulation in mammals. This is further complicated by the transcription-coupled incorporation of the histone variant H3.3 in gene bodies4. Here we show that the candidate tumor suppressor ZMYND11 specifically recognizes H3K36me3 on H3.3 (H3.3K36me3) and regulates Pol II elongation. Structural studies reveal that in addition to the trimethyl-lysine binding by an aromatic cage within the PWWP domain, the H3.3-dependent recognition is mediated by the encapsulation of the H3.3-specific “Ser31” residue in a composite pocket formed by the tandem bromo-PWWP domains of ZMYND11. ChIP-sequencing analysis reveal a genome-wide colocalization of ZMYND11 with H3K36me3 and H3.3 in gene bodies, and its occupancy requires the pre-deposition of H3.3K36me3. Although ZMYND11 is associated with highly expressed genes, it functions as an unconventional transcription corepressor via modulating the transition of the promoter-proximal paused Pol II to elongation. ZMYND11 is critical for the repression of a transcriptional program that is essential for tumor cell growth; higher expression of ZMYND11 is observed in triple-negative breast cancer patients with better prognosis. Consistently, overexpression of ZMYND11 suppresses cancer cell growth and tumor formation in mice. Together, this study identifies ZMYND11 as an H3.3-specific reader of H3K36me3 that links the histone variant-mediated transcription elongation control to tumor suppression. ChIP-seq analysis of ZMYND11, H3K36me3 in U2OS cells and ZMYND11 knockdown cells; ChIP-seq of H3.3 in Flag-H3.3 stable U2OS cells; RNA-seq of ZNYMD11 depleted U2OS cells.

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.
