(Submitter supplied) We investigated genome wide distribution of H3K36me2, H3K36me3 and H3K27me3 in the presence and absence of MMSET protein. MMSET overexpression in t(4;14)+ myeloma leads to global loss redistribution of H3K36me2 and genome-wide loss of H3K27 methylation. Despite the gloal decrease in H3K27me3, specific regions of the genome show enhanced H3K27me3 enrichment through increased recruitment of EZH2 methyltransferase

(Submitter supplied) We investigated gene expression in isogenic myeloma cell lines with or without overexpressed MMSET protein. MMSET is a histone methyltransferase which methylates lysine 36 on histone H3. Overexpression of MMSET in myeloma leads to a global increase in H3K36 methylation and concomitant decrease in H3K27 methylation. These global changes in histone methylation lead to altered gene expression.

(Submitter supplied) The MMSET (Multiple Myeloma SET domain) protein is overexpressed in multiple myeloma patients with the translocation t(4;14). Although studies have shown the involvement of MMSET/WHSC1 in development, its mode of action in the pathogenesis of multiple myeloma (MM) is largely unknown. We found that MMSET is a major regulator of chromatin structure and transcription in t(4;14) MM cells. High levels of MMSET correlate with an increase in lysine 36 methylation of histone H3 and a decrease in lysine 27 methylation across the genome, leading to a more open structural state of the chromatin. more...

(Submitter supplied) 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. more...

(Submitter supplied) Histone methyltransferases (HMTases), as chromatin modifiers, regulate the transcriptomic landscape in normal development as well in diseases such as cancer. Here, we molecularly order two HMTases, EZH2 and MMSET that have established genetic links to oncogenesis. EZH2, which mediates histone H3K27 trimethylation and is associated with gene silencing, was shown to be coordinately expressed and function upstream of MMSET, which mediates H3K36 dimethylation and is associated with active transcription. more...

(Submitter supplied) in this study we define an epigenomic profile of PRC2 (H3K27me3 and bivalent) tragets in four newly diagnosed MM patients. Using Oncomine database we demonstarte that PRC2 targets are underexpressed with advanced ISS stages and correlated to poor outcome. Pharmacological inhibition of UNC1999 showed anti-myeloma potential in vitro by activating the expression genes related to apoptosis and cell differenatiation.

(Submitter supplied) Multiple myeloma (MM) is a hematopoietic malignancy characterised by the accumulation of neoplastic post-germinal centre, isotype-switched, long-lived plasma cell within the bone marrow. In genetic and clinical terms MM is highly heterogeneous and remains fatal. Here we present the first epigenomic map of MM derived from freshly isolated bone marrow plasma cells from four patients. Using ChIP- and RNA-sequencing we define a set of silent H3K27me3 targets, active genes bearing H3K4me3, and bivalent genes.

(Submitter supplied) Trimethylation on H3K27 (H3K27me3) mediated by Polycomb repressive complex 2 (PRC2) has been linked to embryonic stem cell (ESC) identity and pluripotency. EZH2, the catalytic subunit of PRC2, has been reported as the sole histone methyltransferase that methylates H3K27 and mediates transcriptional silencing. Analysis of Ezh2(-/-) ESCs suggests existence of an additional enzyme(s) catalyzing H3K27 methylation. more...
