  1. ...to segregate chromosomes, are typically found within satellite arrays in plants and animals. Satellite arrays have been difficult to analyze because they comprise megabases of tandem head-to-tail highly repeated DNA sequences. Much evidence suggests that centromeres are epigenetically defined by the location...

  2. ...and others have revealed significant rewiring of the metabolic, epigenetic, and transcriptomic signatures of cells in this transition (Fu et al. 2014; Boroviak et al. 2015; Hussein et al. 2020; Collignon et al. 2023; Iyer et al. 2023; van der Weijden et al. 2024). Among these are altered RNA methylation...
  3. ...in the AG and GG blastocysts. Novel candidate imprinted DMRs were also identified. The production of uniparental human embryos followed by transcriptome and methylome analysis is valuable for identifying parental contributions and epi memory transitions during early human development.Uniparental embryos...
  4. ...points, and conditions (Roadmap Epigenomics Consortium et al. 2015), approaches like CMINT will become increasingly useful to examine the chromatin state dynamics and identify important epigenetic transitions changing global cellular states. Methods ChIP-chip experiments ChIP-chip experiments were...
  5. ...in the transition/transversion ratio, the mutation spectrum, or the genomic distribution of dnSNVs between cohorts. Similarly, we observe no differential enrichment of dnSNVs across various epigenetic contexts or with respect to GC content, local transcriptional activity, or replication timing.Future studies...
  6. ...have limited application for discerning epigenetically distinct subpopulations within tumors. This makes it difficult to determine whether plasticity or lineage transitions are a result of Darwinian selection of rare, pre-existing clones, or adaptation, in which dynamic epigenetic changes may activate...
  7. ...insertions and lineage-specific duplicated genes. Our findings suggest independent evolution of subterminal caps converging on a common genetic and epigenetic structure that promoted ectopic exchange as well as the emergence of novel genes at transition regions between euchromatin and heterochromatin...
  8. ...cell. This process is orchestrated by changes 11 in transcriptional regulation, influenced by chromatin accessibility and 12 epigenetic modifications, enabling transcription factor accessibility. Epigenomic 13 regulation of embryogenesis has been studied in model fish, but little attention 14 has been...

  9. ...). These regions are essential for regulating approximately 200 imprinted genes in mammals, which are expressed in a parent-of-origin-specific manner. ICRs are emerging as “Swiss-army knife” regulatory elements that, by integrating epigenetic signals and influencing the three-dimensional (3D) chromatin structure...
  10. ...Zebrafish mRNA sequencing deciphers novelties in transcriptome dynamics during maternal to zygotic transition Håvard Aanes 1 , 9 , Cecilia L. Winata 2 , 9 , Chi Ho Lin 3 , Jieqi P. Chen 4 , Kandhadayar G. Srinivasan 2 , Serene G...
