(Submitter supplied) We quantified the targets and kinetics of DNA methylation acquisition in mouse embryos, and determined the contribution of the de novo methyltransferases DNMT3A and DNMT3B to this process. We provide single-base maps of cytosine methylation by RRBS from the blastocysts to post-implantation stages and in embryos lacking DNMT3A or DNMT3B activity, and performed RNA-Seq in embryos lacking DNMT3B activity.

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) Methylation of cytosines (5meC) is a widespread heritable DNA modification. During mammalian development, two global demethylation events are followed by waves of de novo DNA methylation. In vivo mechanisms of DNA methylation establishment are largely uncharacterized. Here we use Saccharomyces cerevisiae as a system lacking DNA methylation to define the chromatin features influencing the activity of the murine DNMT3B. more...

(Submitter supplied) DNA methylation is a central epigenetic modification that has essential roles in cellular processes including chromatin structure, gene regulation, development and disease. The de novo DNA methyltransferases are responsible for the generation of genomic methylation patterns, but the underlying mechanisms are still poorly understood. Here, we show that phosphorylation of DNMT3A by the CK2 protein kinase regulates the establishment of DNA methylation patterns. more...

(Submitter supplied) CpG islands (CGIs) including those at imprinting control regions (ICRs) are protected from de novo methylation in somatic cells. However, many cancers often exhibit CGI hypermethylation, implying that the machinery is impaired in cancer cells. Here, we conducted a comprehensive analysis of CGI methylation during the somatic cell reprogramming. Although most CGIs remain hypomethylated, a small subset of CGIs, particularly at several ICRs, were often de novo methylated in reprogrammed pluripotent stem cells (PSCs). more...

(Submitter supplied) DNA methylation plays essential roles in mammalian development. During post-implantation development, de novo establishment of DNA methylation is accomplished by DNA methyltransferases, in particular DNMT3A and DNMT3B. At present, the distinct functions of these two enzymes remain largely elusive. To comprehensively identify the target sites for de novo DNA methylation by the DNMT3 enzymes, we took advantage of female mouse ES cells established in the presence of MEK and Gsk3 inhibitors, which lack most DNA methylation (2i/L ES cells), in combination with genetic ablation of Dnmt3a or Dnmt3b. more...

(Submitter supplied) In early embryos, DNA methylation is remodelled to initiate the developmental program. For mostly unknown reasons, methylation marks are acquired unequally between embryonic and placental cells. To better understand this, we generated high-resolution maps of DNA methylation in mouse mid-gestation (E10.5) embryo and placenta. We uncovered specific subtypes of differentially methylated regions (DMRs) that contribute directly to the developmental asymmetry existing between mid-gestation embryo and placenta. more...

(Submitter supplied) Mammalian DNA methylation patterns are established by two de novo DNA methyltransferases DNMT3A and DNMT3B, which exhibit both redundant and distinctive methylation activities. However, the related molecular basis remains undetermined. Through comprehensive structural, enzymology and cellular characterizations of DNMT3A and DNMT3B, here we uncovered distinct and interrelated modes-of-action underlying their CpG site and flanking sequence interaction. more...
