GenomicsVitamin C induces Tet-dependent DNA demethylation in ES cells to promote a blastocyst-like methylome [MeDIP-Seq]
DNA methylation is a heritable epigenetic modification involved in gene silencing, imprinting, and the suppression of retrotransposons. Global DNA demethylation occurs in the early embryo and the germline and may be mediated by Tet (ten-eleven-translocation) enzymes, which convert 5-methylcytosine (...

GenomicsMaintenance of DNA methylation in embryonic stem cells depends on the histone H3K9 methyltransferases (K9 KO 5hmC-capture-seq)
During mammalian development DNA methylation patterns need to be reset in primordial germ cells (PGC) and preimplantation embryos. However, many retro-transposons and imprinted genes are resistant to such global epigenetic reprogramming via hitherto undefined mechanisms. Here, we report that some of...

TranscriptomicsRepeat elements study in pluripotent stem cells [RNA-seq]
We surveyed RNA-Seq data to identify those TEs that are transcriptionally active uniquely in human pluripotent cells. We identified one endogenous retrovirus (HERV-H) family, uniquely found in primates as being unusually abundant in the transcriptome. Poly(A)+ RNA extraction and further sequencing l...
