(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...

(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 through the so-called alternative lengthening of telomere (ALT) mechanism. However, the detailed molecular mechanism of telomere resetting in early embryos remains unknown. Here, we showed that Dcaf11 participates in telomere elongation in early embryos and 2-cell-like embryonic stem cells (ESCs) in a telomerase-independent manner. more...

(Submitter supplied) Purpose:The goals of this study are to understand the mechanisms underlying reduced self-renewal and loss of pluripotency by depletion of Rif1. Methods: We performed global gene expression analysis of Rif1 knockdown ES cell lines using Affymetrix 430 2.0 arrays, compared to shRNA controls.

(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) Pluripotent mouse embryonic stem cells (ESCs) were originally derived and stably maintained on feeder cells such as inactivated mouse embryo fibroblasts, and can generate complete ESC-pups by tetraploid embryo complementation (TEC), the most stringent functional test of naive pluripotency. Remarkably, 2i (inhibitors of Mek and Gsk3β signaling) medium with LIF in the absence of serum and feeders was developed to achieve ground state of mouse ESCs, and also has been successfully used for derivation of germline competent ESCs in other species such as rat. 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) The gold standard for examining pluripotency of stem cells is to see whether cells can contribute to entire body of animals. Here we show that the increased frequency of Zscan4 activation in mouse ES cells not only enhances, but also maintains their developmental potency in long-term cell culture. As the potency increases, even a whole animal can be produced from a single ES cell injected into 4N blastocyst at unusually high success rate. more...

(Submitter supplied) We analyzed the genome-wide DNA methylation in Zscan4 overexpressing ES cells. Zscan4 overexpression induced slight DNA demethylation in telomere and major satellite regions. Subsequent genome-wide analysis of non-repeated regions revealed the significant reduction of DNA methylation at Zscan4-dependent hyperacetylation sites. This result indicates that Zscan4 is not only a marker of the Zscan4+ state of ES cells, but also indispensable for the dramatic epigenetic modifications occurring in the Zscan4+ state.

(Submitter supplied) We analyzed the genome-wide chromatin states in Zscan4 positive ES cells (Em+) and Zscan4 negative ES cells (Em-) by using FACS-sorted MC1-ZE7 ES cells. H3K27 hyperacetylation and DNA demethylation were detected in heterochromatic regions of Em+ cells. These results suggested that the heterochromatin is activated in Zscan4 positive state.

(Submitter supplied) This SuperSeries is composed of the SubSeries listed below. Repetitive sequences such as telomeres, centromeres, and retrotransposons are packed in permanently-condensed and transcriptionally-silenced heterochromatin, whose maintenance is critical for the genome stability. We have recently found that mouse ES cells occasionally go through a unique cell state marked by the transient expression of Zscan4, which plays a key role in long-term genome stability. more...

(Submitter supplied) The HELP tagging assay was performed on purified genomic DNAs. The protocol was modified for NEBNext Multiplex Oligos for Illumina (NEB) from the original protocol4 (http://wasp.einstein.yu.edu/index.php/Protocol:HELP_tagging). Briefly, genomic DNA was digested by HpaII or MspI, the former only cutting at CCGG sequences where the central CG dinucleotide is unmethylated. AS and AE adapters were prepared by annealing two oligo DNAs separately. more...

(Submitter supplied) By using FACS-sorted MC1-ZE7 ES cells, we analyzed the genome-wide distribution of H3K27ac and DNA methylation in Zscan4 positive ES cells (Em+) and Zscan4 negative ES cells (Em-). H3K27 hyperacetylation and DNA demethylation were detected in heterochromatic regions of Em+ cells, but not Em- cells. These results suggested that the Zscan4 state takes "open" chromatin conformation in ES cells.
