(Submitter supplied) Subsets of endogenous retroviruses (ERVs) are derepressed in mouse embryonic stem cells (mESCs) deficient for Setdb1, which catalyzes histone H3 lysine 9 trimethylation (H3K9me3). Most of those ERVs, including IAPs, remain silent if Setdb1 is deleted in differentiated embryonic cells; however they are derepressed when deficient for Dnmt1, suggesting that Setdb1 is dispensable for ERV silencing in somatic cells. more...

(Submitter supplied) Genetic ablation of the maintenance methyltransferase Dnmt1 induces widespread demethylation and transcriptional activation of CpG-rich IAP (intracisternal A particle) proviruses. Here, we report that this phenomenon is not simply a consequence of loss of DNA methylation. By exploiting conditional deletions of Dnmt1 and Np95, each of which is essential for maintenance methylation, we find that while IAPs are indeed de-repressed in Dnmt1-ablated embryos and embryonic stem cells (ESCs), these proviruses remain silenced in Np95-ablated cells, despite similar kinetics of passive demethylation. more...

(Submitter supplied) Genome stability relies on epigenetic mechanisms that enforce repression of endogenous retroviruses (ERVs). Current evidence suggests that distinct chromatin-based mechanisms repress ERVs in cells of embryonic origin (histone methylation-dominant) versus more differentiated cells (DNA methylation-dominant). However, the latter aspect of this model has not been tested. Remarkably, and in contrast to the prevailing model, we find that repressive histone methylation catalyzed by the enzyme SETDB1 is critical for suppression of specific ERV families and exogenous retroviruses in committed B-lineage cells from adult mice. 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) DNA methylation and histone H3 lysine 9 trimethylation (H3K9me3) play important roles in silencing of genes and retroelements. However, a comprehensive comparison of genes and repetitive elements repressed by these pathways has not been reported. Here we show that in mouse embryonic stem cells (mESCs), the genes up-regulated following deletion of the H3K9 methyltransferase Setdb1 are distinct from those de-repressed in mESC deficient in the DNA methyltransferases Dnmt1, Dnmt3a and Dnmt3b, with the exception of a small number of primarily germline-specific genes. more...

(Submitter supplied) Silencing of endogenous retroviruses (ERVs) is largely mediated by repressive chromatin modifications, such as H3K9me3 and DNA methylation. Their impact on ERV silencing differs in various cell types and, no systematic analyses on the interdependence between H3K9me3 and DNA methylation have been performed in differentiated cells. Here we show that deletion of the H3K9me3 HMTase Setdb1 in mouse embryonic endoderm results in ERV de-repression in only a subset of endoderm cells. more...
