(Submitter supplied) Oocyte acquires developmental competence during its maturation. This stage is accompanied with large-scale alteration in transcription, and series of genome-wide epigenetic reprogramming, including de novo establishment of DNA methylation. However, our understanding of mechanisms regulating this process is limited. To investigate the role of Stella (Dppa3) in de novo methylation during mouse oogenesis, here we measured DNA methylation by RRBS and expression profiles by RNA-seq in PGCs and oocytes at serveral development stages, including genotypes of both Stella (Dppa3) +/- and Stella -/-.

(Submitter supplied) Accumulative studies indicate that DNA maintenance methylation by DNMT1 is initiated by binding of UHRF1 to replication fork. However, how UHRF1 gains access to chromatin in S phase is poorly understood. Here we report that LSH, a SNF2 family chromatin remodeler, facilitates DNA methylation in somatic cells primarily by promoting DNA methylation by DNMT1. We show that knockout of LSH in various somatic cells resulted in substantial reduction of DNA methylation, whereas knockout of DNMT3A and DNMT3B only moderately reduced the level of DNA methylation. more...

(Submitter supplied) This SuperSeries is composed of the SubSeries listed below. DNA methylation is an epigenetic modification associated with transcriptional repression of promoters and is essential for mammalian development. Establishment of DNA methylation is mediated by the de novo DNA methyltransferases DNMT3A and DNMT3B, whereas DNMT1 ensures maintenance of methylation through replication. Absence of these enzymes is lethal, and somatic mutations in these genes have been associated with several human diseases. more...

(Submitter supplied) Cytosine methylation (5mC) plays a key role in maintaining progenitor cell self-renewal and differentiation. Here, we analyzed the role of 5mC in kidney development by genome-wide methylation and expression profiling and by systematic genetic targeting of DNA methyltransferases (Dnmt) and Tet eleven hydroxylases (Tet). In mice, nephrons differentiate from Six2+ progenitor cells, therefore we created animals with genetic deletion of Dnmt 1, 3a, 3b, Tet1, or Tet2 in the Six2+ population (Six2Cre/Dnmt1flox/flox, Six2Cre/Dnmt3aflox/flox, Six2Cre/Dnmt3bflox/flox, Six2Cre/Tet2flox/flox or Tet1-/-). more...

(Submitter supplied) DNA methylation plays a critical role in development, particularly in silencing transposable elements. Conserved across mammals, the methylation landscape is dependent on the combined activities of the canonical maintenance enzyme Dnmt1 and the de novo Dnmts 3a and 3b. Here we demonstrate that Dnmt1 displays clear de novo activity in vitro and in vivo and is specifically directed to IAP retrotransposons. more...

(Submitter supplied) Development of a multicellular organism uses the same genetic code to generate a broad diversity of cell types, which is instructed by extracellular cues and orchestrated by transcriptional activators and repressors.

(Submitter supplied) Mouse embryos acquire global DNA methylation of their genome during implantation. However the exact roles of DNA methyltransferases (DNMTs) in embryognesis have not been studied comprehensively. Here we systematically analyze the consequences of genetic inactivation of Dnmt1, Dnmt3a and Dnmt3b on the methylome and transcriptome of mouse embryos and fibroblasts.

In humans, SCMC gene variants were found in the healthy mothers of children affected by multi-locus imprinting disturbances (MLID). However, how the SCMC controls the DNA methylation required to regulate imprinting remains poorly defined. more...

(Submitter supplied) 5-methylcytosine is a major epigenetic modification sometimes called "the fifth nucleotide". However, our knowledge of how offspring inherit the DNA methylome from parents is limited. We generated nine single-base resolution DNA methylomes including zebrafish gametes and early embryos. The oocyte methylome is significantly hypo-methylated compared to sperm. Strikingly, the paternal DNA methylation pattern is maintained throughout early embryogenesis. more...

(Submitter supplied) During early mammalian development, DNA methylation undergoes two waves of reprogramming, enabling transitions between somatic cells, oocyte and embryo. The first wave of de novo DNA methylation establishment occurs in the oocytes. Its molecular mechanisms has been studied in mouse, a classical mammalian model. Current dogma describes DNA methyltransferase 3A (DNMT3A) and its cofactor DNMT3L as two essential factors for oocyte DNA methylation – the ablation of either leads to nearly complete abrogation of DNA methylation. more...

(Submitter supplied) We show the application of 5mC antibody-based methylated DNA immunoprecipitation followed sequencing technology for high-through profiling of DNA methylation in mouse C2C12 myoblasts and myotubes. By analyzing the methylation status of immunoprecipitated DNA fragments, we generated genome-wide DNA methyaltion maps in mouse C2C12 myoblasts and myotubes. We find that DNA methylation levels in myoblasts at rDNA promter and coding regions are higher than that in myotubes but not changed in intergenic regions.

(Submitter supplied) Faithful maintenance of genomic imprinting is essential for mammalian development. While germline DNA methylation-dependent (canonical) imprinting is relatively stable during development, the recently discovered oocyte-derived H3K27me3-mediated noncanonical imprinting is mostly transient in early embryos with only a few genes maintain imprinted expression in the extraembryonic lineage. How these few noncanonical imprinted genes maintain their extraembryonic-specific imprinting is unknown. more...

(Submitter supplied) The maternal to zygotic transition (MZT) involves the transfer of genome regulation from the oocyte to the embryo and is essential for the formation of totipotent embryos. However, regulatory mechanisms are still poorly understood despite recent progress in mapping the dynamics in RNA transcripts and DNA methylation1-9. Previous studies suggest that dynamic histone modifications may play important roles in MZT10-12, however direct measurements of chromatin states has been hindered by technical difficulties in profiling histone modifications from small quantities of cells. more...
