(Submitter supplied) We found that Rif1 depletion leads to reduced H3K9me3 levels at 1/3 of the H3K9me3-enriched genomic regions (H3K9me3 peaks), and that reduced H3K9me3 de-represses Zscan4 and other genes that are specific to the 2-Cell stage embryo.

(Submitter supplied) Transposable elements, including endogenous retroviruses (ERVs), constitute a large fraction of the mammalian genome. They are transcriptionally silenced during early development to protect genome integrity and aberrant transcription. However, the mechanisms that control their repression are not fully understood. To systematically study ERV repression, we carried out an RNAi screen in mouse embryonic stem cells (ESCs) and identified a list of novel regulators. more...

(Submitter supplied) Occupancy profiling of Shelterin components in fission yeast. Facultative heterochromatin regulates gene expression, but its assembly is poorly understood. Previously, we identified facultative heterochromatin islands in the fission yeast genome and found that RNA elimination machinery promotes island assembly at meiotic genes. Here, we report that Taz1, a component of the telomere protection complex Shelterin, is required to assemble heterochromatin islands at regions corresponding to late replication origins that are sites of double-strand break formation during meiosis. more...

(Submitter supplied) Chemical induced pluripotent stem cells (CiPSCs) have been successfully achieved and may provide an alternative and attractive source for stem cell-based therapy. Sufficient telomere lengths are critical for unlimited self-renewal and genomic stability of pluripotent stem cells. Dynamics of telomere reprogramming and whether and how telomeres are sufficiently elongated in the CiPSCs have remained to be understood. more...

(Submitter supplied) Rif1 depletion in mouse ES cells increases the populations derepressing 2-cell zygote-specific genes including Zscan4. We investigated the chromatin structural change in the Zscan4 gene loci, and found that this region was deprived of major histone modifications except for moderately coded by H3 lysine9 trimethylation. Rif1 depletion caused no significant alteration in DNA methylation and histone modifications including common active marks, but only a notable increase in H3K27Ac active mark in gene bodies and neighboring regions, indicating that atypical broad enhancer-like chromatin with semi-silent property has been emerged in Zscan4 gene loci.<BR>In this study, we used microarrays to present the global changes in gene expression caused by transient depletion of Rif1.

(Submitter supplied) Telomeres play vital roles in ensuring chromosome stability and are thus closely linked with the onset of aging and human disease. Telomeres undergo extensive lengthening during early embryogenesis. However, the detailed molecular mechanism of telomere resetting in early embryos remains unknown. Here, we show that Dcaf11 (Ddb1- and Cul4-associated factor 11) participates in telomere elongation in early embryos and 2-cell-like embryonic stem cells (ESCs). more...
