(Submitter supplied) Genome wide chromatin maps have shown that spreading repressive histone modifications such as H3K9me3 and H4K20me3 are present on pericentromeric and telomeric repeats and on the inactive X chromosome where H3K27me3 or H3K9me3 alternately modify megabasepair sized domains. However, only a few regions along an autosome of which Homeobox gene clusters are notable examples, have been shown to display spreading of repressive histone modifications. more...

(Submitter supplied) Retrotransposons are widely spread in the mammalian genome and are usually silenced during development to avoid transposition-inducing mutations. But how they are repressed in embryos shortly before implantation remain to be identified, since the genome at this stage is globally hypomethylated. Here we show a histone chaperon, CAF-1, is responsible for retrotransposon silencing at the morula-blastocyst stages by depositing histone H4 lysine 20 trimethylation (H4K20me3). more...

(Submitter supplied) Bivalent chromatin domains consisting of the activating histone 3 lysine 4 trimethylation (H3K4me3) and repressive histone 3 lysine 27 trimethylation (H3K27me3) histone modifications are enriched at developmental genes that are repressed in embryonic stem cells but active during differentiation. However, it is unknown whether another repressive histone modification, histone 4 lysine 20 trimethylation (H4K20me3), co-localizes with activating histone marks in ES cells. more...

(Submitter supplied) The Igf2r imprinted cluster is an epigenetic model of cis-acting silencing in which expression of a ncRNA silences multiple genes. Here, we map chromatin profiles on the maternal and paternal chromosome in a 250 kb region. We show that histone modifications associated with expressed and silent genes are mutually exclusive and localize to discrete regions. Expressed genes are modified in two ways; at promoter regions by H3K4me3+H3K4me2+H3K9Ac and on putative regulatory elements by H3K4me2+H3K9Ac. more...

(Submitter supplied) Cross-talk between DNA methylation and histone modifications drives the establishment of composite epigenetic signatures and is traditionally studied using correlative rather than direct approaches. Here we present sequential ChIP-bisulfite-sequencing (ChIP- BS-seq) as an approach to quantitatively assess DNA methylation patterns associated with chromatin modifications or chromatin-associated factors directly. more...

(Submitter supplied) Transcription of endogenous retroviruses (ERVs) is inhibited by de novo DNA methylation during gametogenesis, a process initiated after birth in oocytes and at ~E15.5 in prospermatogonia. Earlier in germline development however, the genome, including most retrotransposons, is progressively demethylated, with young ERVK and ERV1 elements retaining intermediate methylation levels. As DNA methylation reaches a low point in E13.5 primordial germ cells (PGCs) of both sexes, we determined whether retrotransposons are marked by H3K9me3 and H3K27me3 using a recently developed low input ChIP-seq method. more...

(Submitter supplied) Histone modifications play critical roles in regulating developmental genes expression during embryo development in mammals1,2. However, genome-wide analysis of histone modifications in pre-implantation embryos has been impeded by technical difficulties and the scarcity of required materials. Here, by using a small-scale chromatin immunoprecipitation sequencing (ChIP-seq) method3, for the first time, we mapped the genome-wide profile of histone H3 lysine 4 trimethylation (H3K4me3) and histone H3 lysine 27 trimethylation (H3K27me3), associated with gene activation and repression respectively, in mouse pre-implantation embryos. more...

(Submitter supplied) Epigenetic regulation of chromatin states is thought to control the self-renewal and differentiation of embryonic stem (ES) cells. However, the roles of repressive histone modifications such as trimethylated histone lysine 20 (H4K20me3) in pluripotency and development are largely unknown. Here, we show that the histone lysine methyltransferase SMYD5 mediates H4K20me3 at heterochromatin regions. Depletion of SMYD5 leads to compromised self-renewal, including dysregulated expression of OCT4 targets, and perturbed differentiation. more...

(Submitter supplied) Neural stem progenitor cells (NSPCs) in the human subventricular zone (SVZ) potentially contribute to life-long neurogenesis, yet subtypes of glioblastoma multiforme (GBM) contain NSPC signatures that highlight the importance of cell fate regulation. Among numerous regulatory mechanisms, the post-translational methylations onto histone tails are crucial regulator of cell fate. The work presented here focuses on the role of two repressive chromatin marks tri-methylations on histone H3 lysine 27 (H3K27me3) and histone H4 lysine 20 (H4K20me3) in the adult NSPC within the SVZ. more...

(Submitter supplied) Only a small percentage of human transcription factors (e.g. those associated with a specific differentiation program) are expressed in a given cell type. Thus, cell fate is mainly determined by cell type-specific silencing of transcription factors that drive different cellular lineages. Several histone modifications have been associated with gene silencing, including H3K27me3 and H3K9me3. We have previously shown that the two largest classes of mammalian transcription factors are marked by distinct histone modifications; homeobox genes are marked by H3K27me3 and zinc finger genes are marked by H3K9me3. more...
