  1. ...). In early mouse embryos, imprinted XCI (iXCI), which always inactivates the paternal X Chromosome, takes place at the four-cell stage. It is followed by XCR, in the inner cell mass (ICM) of the blastocyst (Mak et al. 2004; Okamoto et al. 2004; Borensztein et al. 2017a, b). Then, random XCI (rXCI) of one...
  2. ...or one. In the case of perfectly balanced X inactivation, haplotype blocks should return skews of 0.5. Folding is done around the x = 0.5 axis, to account for the random assignment of haplotype 1/2 labels to the two alleles in each block. Folding would not be necessary if we could assign haplotype 1...
  3. ...somatic cells throughout life (Straub and Becker 2007; Payer and Lee 2008). XCI occurs in two distinct patterns in eutherian mammals: random XCI (rXCI) and paternally imprinted XCI (pXCI). In rXCI, the choice of X chromosome to be inactivated in any given cell is more or less random with regard...
  4. ...485 total horses. Genotypes were phased with Beagle version 4.0 (Browning and Browning 2007) to fill in missing genotypes and predict haplotypes.Recombination rate estimation and hotspot detectionOne hundred random samples of 40 chromosomes from the data set described above were generated to estimate...
  5. ..., and their function in development is unknown. In this study, we developed a -wide approach to identify novel imprinted DMRs in the human placenta and investigated the dynamics of these imprinted DMRs during development in somatic and extraembryonic tissues. DNA methylation was evaluated using the Illumina Human...
  6. ...directional RNA preparation kit (New England Biolabs E7760S) following the manufacturer's instructions. Briefly, nascent RNA was fragmentated into an average of 200 nt and reverse-transcribed into stranded DNA using random primers, which was followed by addition of sequencing bar-code during PCR amplification...
  7. ...consequences of XCI escape, a critical first step is to identify genes that escape XCI in a particular tissue or disease state. The chromosome-wide analysis is complicated by the random nature of XCI in early development, as the determination of Xa and Xi Chromosomes differs from cell to cell (cellular...
  8. ...True single-molecule DNA sequencing of a pleistocene horse bone Ludovic Orlando 1 , 9 , Aurelien Ginolhac 1 , Maanasa Raghavan 1 , Julia Vilstrup 1 , Morten Rasmussen 1 , Kim Magnussen 1 , Kathleen E. Steinmann 2...
  9. .... In contrast to mESCs, mouse EpiStem cells (mEpiSCs) represent a primed developmental state of pluripotency, defined by their propensity for differentiation and random XCI, representing a suitable model for post-implantation development (Brons et al. 2007; Tesar et al. 2007). Random XCI is a crucial event...
  10. ...be required for the regulation of gene activity. However, random replication has not been observed in mammals or outside the context of embryonic development. In mammals, developmentally regulated, chromosome-wide transcriptional silencing occurs in the process of X chromosome inactivation (XCI). XCI...
