Chromosome wide analysis of parental allele specific chromatin and DNA methylation along the central part of mouse chr7

ABSTRACT: Imprinted genes are monoallelically expressed according to parental inheritance. The maternally and paternally inherited alleles are distinguished epigenetically by DNA methylation and histone modifications. Chromosome-wide Chromatin immunoprecipitation (ChIP) and MIRA analysis of MatDup.dist7 and PatDup.dist7 MEFs provided a panoramic map of reciprocal allele-specific histone modifications and DNA methylation at imprinted genes along distal chromosome 7 and 15. ChIP-chip and MIRA-chip was done to map histone modifications and DNA methylation along central chr7 in the maternal allele and paternal allele in Matdup.dist7 and Patdup.dist7 MEFs, respectively, using Nimblegen tiling arrays for central chr7.

To reveal the extent of domain-wide epigenetic features at imprinted gene clusters, we performed a high-resolution allele-specific chromatin analysis of over 100 megabases along the maternally or paternally duplicated distal chromosome 7 (Chr7) and Chr15 in mouse embryo fibroblasts (MEFs). We found that reciprocal allele-specific features are limited to imprinted genes and their differentially methylated regions (DMRs), whereas broad local enrichment of H3K27me3 (BLOC) is a domain-wide feature a ...[more]

Dynamics of 5-hydroxymethylcytosine and chromatin marks in mammalian neurogenesis

Project description:H3K36me3 (ChIp-ChIp), H3K4me3 (ChIp-ChIp), H3K27me3 (ChIp-ChIp), 5mC (MIRA) and 5hmC (hMeDIP) profiles were analyzed in neural progenitor cells (NPC) and neurons by using Nimblegen Mouse ChIP-chip 2.1M Economy Whole-Genome Tiling - 4 Array Set. In order to compare two different techniques of 5hmC profiling, we performed 5hmC profiling with Hydroxymethyl Collector™ Kit (Active Motif) method and hybridized it on mouse Chr7 fragment (Nimblegen). As an independent experiment, 5hmC profiling was performed by using hMeDIP method and hybridized on mouse Chr7 fragment (Nimblegen). After MIRA enrichment and genome amplification, DNA was hybridized on mouse Chr7 fragment (Nimblegen). Analysis of epigenetic changes during neural differentiation due to comparisson of epigenetic patterns in neural progenitor cells versus neurons.

Allele-specific binding of ZFP57 in the regulation of imprinted and mono-allelic expression

Project description:Selective maintenance of genomic methylation imprints during pre-implantation development is required for parental origin-specific expression of imprinted genes. The Kruppel-like zinc finger protein ZFP57 acts as a factor necessary for maintaining the DNA methylation memory at multiple imprinting control regions (ICRs) in early mouse embryos and ES cells. Maternal-zygotic deletion of ZFP57 in mice presents a highly penetrant phenotype with no animals surviving to birth. In addition, several cases of human transient neonatal diabetes (TND) are associated with somatic mutations in ZFP57 coding sequence. Here we comprehensively map sequence-specific ZFP57 binding sites in an allele-specific manner using hybrid ES cell lines from reciprocal crosses between C57BL/6J and Cast/EiJ mice assigning allele specificity to approximately two thirds of all binding sites. While half of these are biallelic and include ERV targets, the rest show mono-allelic binding based either on parental-origin or on genetic background of the allele. Parental-origin allele-specific binding was methylation-dependent and mapped only to imprinted DMRs established in the germline (gDMRs). No binding was evident at secondary somatically-derived DMRs. ZFP57-bound gDMRs can predict imprinted gene expression and we identify new imprinted genes, including the Fkbp6 gene with a critical function in mouse male germ cell development. Genetic-background specific sequence differences also influence ZFP57 binding. We show that genetic variation that disrupts the consensus binding motif and its methylation is associated with mono-allelic expression of neighbouring genes. The work described here uncovers further roles for ZFP57 mediated regulation of genomic imprinting and identifies a novel mechanism for genetically determined mono-allelic gene expression. Input and Zfp57 CHiP-Seq profiles of hybrid Black6/Cast ES cells were generated by sequencing using the Illumina GAIIx platform.

Default DNA Methylation is Preceded by Broad, Low-Level Transcription in Fetal Male Germ Cells and Is Inversely Patterned by Dynamic H3K4 Methylation (ChIP-chip and MIRA-chip)

Project description:To understand what dictates the emerging patterns of de novo DNA methylation, we mapped DNA methylation, chromatin, and transcription changes in purified fetal mouse germ cells using MIRA-chip, ChIP-chip, and strand-specific RNA-seq, respectively. De novo methylation occurred without any apparent trigger from preexisting repressing chromatin marks but was preceded by broad, low-level transcription along the entire genome in prospermatogonia. Only distinct short sequences remained unmethylated, precisely aligned with constitutive or emerging peaks of H3K4me2. Establishment of methylation at differentially methylated regions (DMRs) of imprinted genes, CpG islands, and IAPs followed these same default rules. Transcription run-through occurred at paternal DMRs with no- or diminishing H3K4me2 peaks. Maternal DMRs remained unmethylated among highly methylated DNA at precisely aligned H3K4me2 peaks with transcription initiating at least in one strand. Our results suggest that the pattern of de novo DNA methylation in prospermatogonia is dictated by opposing actions of broad, low-level transcription and dynamic patterns of active chromatin. ChIP-chip and MIRA-chip were performed to map histone modifications and DNA methylation at different devlopmental time points in germ cells and somatic cells along known imprinted domains and control regions, using custom NimbleGen tiling arrays.

Quantitative ChIP-MS analysis of histone modifications present on H3K4me1- and H3K4me3-enriched mono-nucleosomes purified from crosslinked IMR-90 cells

Project description:The INO80 complex is a chromatin remodeler that regulates DNA replication, repair, and transcription. Although the INO80 complex plays a crucial role in various chromatin-associated processes, the mechanism of its recruitment to specific genomic loci is not well understood. Here we used a native ChIP-MS approach to quantitatively profile modifications present on nucleosomes co-purified with INO80 from MNAse-digested HeLa chromatin.
