Menin is a ‘reader’ of histone H3 lysine 79 methylation (RNA-Seq)

Project description:Methylation of histone H3 lysine-79 is an epigenetic mark for gene regulation in development, cellular differentiation and disease progression. However, it remains poorly understood how this histone mark is translated into downstream effects due to the lack of knowledge of H3K79 methylation ‘readers’. Here, we develop a nucleosome-based photoaffinity probe to capture proteins that recognize H3K79 dimethylation (H3K79me2) in nucleosomal context. In combination with a quantitative proteomics approach, this probe identifies menin as a bona fide “reader” for H3K79me2. Menin directly and selectively binds to the nucleosome with H3K79me2 mark in vitro. In cells, menin is tightly associated with this histone mark on chromatin, particularly in gene bodies. Reading H3K79me2 at intragenic enhancers, menin promotes gene transcription, likely by mediating enhancer–promoter interactions.

Genome-wide characterization of menin-dependent H3K4me3 reveals a specific role for menin in the regulation of genes implicated in MEN1-like tumors (mRNA)

Project description:Inactivating mutations in the MEN1 gene predisposing to the multiple endocrine neoplasia type 1 (MEN1) syndrome can also cause sporadic pancreatic endocrine tumors. MEN1 encodes menin, a subunit of MLL1/MLL2-containing histone methyltransferase complexes that trimethylate histone H3 at lysine 4 (H3K4me3). The importance of menin-dependent H3K4me3 in normal and transformed pancreatic endocrine cells is unclear. To study the role of menin-dependent H3K4me3, we performed in vitro differentiation of wild-type as well as menin-null mouse embryonic stem cells (mESCs) into pancreatic islet-like endocrine cells (PILECs). Gene expression analysis and genome-wide H3K4me3 ChIP-Seq profiling in wild-type and menin-null mESCs and PILECs revealed menin-dependent H3K4me3 at the imprinted Dlk1-Meg3 locus in mESCs, and all four Hox loci in differentiated PILECs. Specific and significant loss of H3K4me3 and gene expression was observed for genes within the imprinted Dlk1-Meg3 locus in menin-null mESCs and the Hox loci in menin-null PILECs. Given that the reduced expression of genes within the DLK1-MEG3 locus and the HOX loci is associated with MEN1-like sporadic tumors, our data suggests a possible role for menin-dependent H3K4me3 at these genes in the initiation and progression of sporadic pancreatic endocrine tumors. Furthermore, our investigation also demonstrates that menin-null mESCs can be differentiated in vitro into islet-like endocrine cells, underscoring the utility of menin-null mESC-derived specialized cell types for genome-wide high-throughput studies. Genome-wide mapping of H3K4me3 and microarray gene expression profiling in TC-1 wild-type (WT) mESCs, menin-null (Men1-ko) mESCs (3.2N), pancreatic islet-like endocrine cells (PILECs) derived from WT mESCs, and PILECs derived from Men1-ko mESCs.

Histone H3 lysine 27 trimethylation of miRNA genes in HMEC and HMF

Project description:Normal cell type specific histone H3 lysine 27 trimethylation of miRNA genes. HMEC and HMF represent two distinct differentiated cell type present in mammary gland each with a distinct phenotype, a distinct epigenotype as well as distinct miRNA expression pattern. The aim of the study was to determine how epigenetic modifications including histone H3 lysine 27 trimethylation affect miRNA expression. Two cell types HMEC vs. HMF. Biological replicates: 3 pairs of HMEC-HMF of 3 distinct genotypes. Immunoprecipitation using anti-histone H3 trimethylated at lysine 27 (07-449, Millipore).
