(Submitter supplied) During oogenesis, oocytes gain competence to accomplish meiotic maturation and prepare for embryonic development following fertilization. Trimethylated histone H3 on lysine-4 (H3K4me3) mediates a wide range of nuclear events during these processes. Oocyte-specific knockout of CxxC-finger protein 1 (CXXC1, also known as CFP1), the chromatin-binding subunit of SETD1 methyltransferase, impairs the H3K4me3 accumulation during murine oogenesis and caused changes in chromatin configurations. more...

(Submitter supplied) T cell development in the thymus is largely controlled by an epigenetic program involving in both DNA methylation and histone modifications. Previous studies have identified Cxxc1 as a regulator of both cytosine methylation and histone 3 lysine 4 trimethylation (H3K4me3). However, it is unknown whether Cxxc1 plays a role in thymocyte development. Here we show that T cell development in the thymus is severely impaired in Cxxc1-deficient mice. more...

(Submitter supplied) A decrease in oocyte developmental potential is a major obstacle for successful pregnancy in women of advanced age. However, the age-related epigenetic modifications associated with dynamic transcriptome changes, particularly meiotic maturation-coupled mRNA clearance, have not been adequately characterized in human oocytes. This study demonstrate a decreased storage of transcripts encoding key factors regulating the maternal mRNA degradome in fully grown oocytes of women of advanced age. more...

(Submitter supplied) IL-6/STAT3 signalling is known to initiate the Th17 differentiation programme, but the upstream regulatory mechanisms remain minimally explored. Here, we show that Cxxc finger protein 1 (Cxxc1) promoted the generation and stability of Th17 cells as an epigenetic regulator and prevented their differentiation into Treg cells. Mice with a T cell-specific deletion of Cxxc1 were protected from experimental autoimmune encephalomyelitis and were more susceptible to Citrobacter rodentium infection. more...

(Submitter supplied) In most mammals, including mice and humans, meiotic recombination is determined by the meiosis specific histone methytransferase PRDM9, which binds to specific DNA sequences and trimethylates histone 3 at lysine-4 and lysine-36 at the adjacent nucleosomes. These actions ensure successful DNA double strand break formation and repair that occur on the proteinaceous structure forming the chromosome axis. more...

(Submitter supplied) Trimethylation of histone H3 lysine 4 (H3K4me3) accumulates at promoters in a gene activity dependant manner. The Set1 complex is responsible for most H3K4me3 in somatic cells and contains the conserved subunit Cfp1, which is implicated in targeting the Set1 complex to CpG islands in mammals. In mouse embryonic stem cells, Cfp1 is necessary for H3K4me3 accumulation at constitutively active gene promoters, but is not required to maintain steady-state transcription of the associated gene. 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...

(Submitter supplied) Trimethylation of histone 3 lysine 4 (H3K4me3) at promoters of actively transcribed genes is a universal epigenetic mark and a key product of Trithorax-Group action. Here we show that Mll2, one of the six Set1/Trithorax-type H3K4 methyltransferases in mammals, is required for trimethylation of bivalent promoters in mouse embryonic stem cells. Mll2 is bound to bivalent promoters but also to most active promoters, which do not require Mll2 for H3K4me3 or mRNA expression. 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...

(Submitter supplied) Splat-like 4 (Sall4) plays important roles in maintaining pluripotency of embryonic stem cells and in various developmental processes. Here, we find that the SALL4 null oocytes fail to undergo maturation to form fully-grown oocytes (FGOs) and subsequent meiosis resumption. We further discover that the loss of maternal SALL4 causes failure in establishment of DNA methylation. Moreover, we demonstrate that SALL4 modulates H3K4me3 and H3K27me3 modifications by regulating the expression of Kdm5b, Kdm6a and Kdm6b. more...
