(Submitter supplied) Oocytes develop the competence for meiosis and early embryogenesis during their growth. Setdb1 is a histone H3 lysine 9 (H3K9) methyltransferase required for post-implantation development and has been implicated in the transcriptional silencing of genes and endogenous retroviral elements (ERVs). To address its role in oogenesis and pre-implantation development, we conditionally deleted Setdb1 in growing oocytes. more...

(Submitter supplied) We report the first genome-wide landscape of H3K9me2 ChIP-seq profile in mouse oocytes. We also performed whole-genome bisulfite sequencing and RNA-seq analysis of G9a conditional KO oocytes and maternal KO preimplantation embryos. Our findings illuminate the functional importance of G9a in preimplantation development and, in addition, pose a question on the proposed role for H3K9me2 in protection of the maternal genome from active CG demethylation.

(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) 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) Meiotic synapsis and recombination ensure correct homologous segregation and genetic diversity. Asynapsed homologues are transcriptionally inactivated by meiotic silencing, which serves a surveillance function and in males drives meiotic sex chromosome inactivation. Silencing depends on the DNA damage response (DDR) network, but how DDR proteins engage repressive chromatin marks is unknown. We identify the histone H3-lysine-9 methyltransferase SETDB1 as the bridge linking the DDR to silencing in male mice. more...

(Submitter supplied) The lysine methyltransferase SETDB1, an enzyme responsible for methylation of histone H3 at lysine 9, plays a key role in H3K9 tri-methylation dependent silencing of endogenous retroviruses and developmental genes. Recent studies have shown that ubiquitination of human SETDB1 complements its catalytic activity and the silencing of endogenous retroviruses in human embryonic stem cells. However, it is not known whether SETDB1 ubiquitination is essential for its other major role in epigenetic silencing of developmental gene programs. more...

(Submitter supplied) We report the application of single-molecule-based sequencing technology for high-throughput profiling of histone modifications in mammalian cells and characterized genome-wide SetDB1 binding and H3K9 trimethylation (H3K9me3) profiles in mouse ES cells and uncovered two distinct classes of SetDB1 binding sites, termed solo and ensemble peaks. The solo peaks were devoid of H3K9me3 and enriched near developmental regulators while the ensemble peaks were associated with H3K9me3. more...

(Submitter supplied) DNA from mature sperm was obtained from a mouse heterozygous for a mutation in Setdb1 (MommeD13) and a wildtype control mouse. The DNA was bisulfite converted and sequenced on a HiSeq 2000 to ~30x coverage. After mapping the resulting reads to the mouse genome DNA methyalation values at CpG dinucleotides were obtained as the ratio of reads with unconverted Cs relative to the sum of converted and unconverted reads. more...

(Submitter supplied) SETDB1 is a histone methyltransferase with essential roles in mouse development. It mediates transcriptional repression of genes and repetitive elements in different cell-types by depositing histone H3 lysine 9 trimethylation (H3K9me3). However, the function of differential H3K9me3 enrichment between cell- and tissue-types remains unclear. In this study, we demonstrate a global mutual exclusivity of H3K9me3 and CTCF across mouse tissues from different developmental time points. more...

(Submitter supplied) Sexual reproduction involves the creation of sex-dependent gametes, oocytes and sperm. In mammals, sexually dimorphic differentiation commences in the primordial germ cells (PGCs) in embryonic gonads; PGCs in ovaries and testes differentiate into meiotic primary oocytes and mitotically quiescent prospermatogonia, respectively. Here, we show that the transition from PGCs to　sex-specific germ cells was abrogated in conditional knockout mice carrying a null mutation of Smarcb1 (also known as Snf5) gene, which encodes a core subunit of the SWI/SNF chromatin remodeling complex. more...

(Submitter supplied) The oocyte epigenome plays critical roles in mammalian gametogenesis and embryogenesis. Yet, how it is established remains elusive. Here, we report that histone-lysine N-methyltransferase SETD2, an H3K36me3 methyltransferase, is a crucial regulator of the mouse oocyte epigenome. Deficiency in Setd2 leads to extensive alterations of the oocyte epigenome, including the loss of H3K36me3, failure in establishing the correct DNA methylome, invasion of H3K4me3 and H3K27me3 into former H3K36me3 territories and aberrant acquisition of H3K4me3 at imprinting control regions instead of DNA methylation. more...
