  1. ...421 developmental transitions and lineage specification 422 To identify the main TFs associated with chromatin accessibility dynamics in 423 candidate CREs regulated during embryogenesis, TFBM enrichment was 424 conducted for all DARs associated with promoters and putative enhancers. 425 Significant...

  2. ...; Davis et al. 2018).A key issue within developmental biology involves how embryos transition from a totipotent to a lineage-committed state, and higher-order chromatin structures are known to influence enhancer–promoter interaction potential for developmental genes. To better understand, we sought...
  3. ...of the wild type (Fig. 1C). Dgcr8 KO ESC colonies were lost within 2–3 d of MTORi (Fig. 1A,B). Therefore, a specific dependence on DGCR8 arises in ESCs during the dormancy transition. To corroborate this outcome within the setting of embryonic pluripotency, we generated chimeric embryos by aggregating diploid...
  4. ...the abnormalities in the different organs are driven by the same underlying chromatin disruption in the corresponding cell types. In other words, are the chromatin effects of variants in epigenetic regulators shared between different cell types or are they primarily cell type specific?There are two major reasons...
  5. ...embryogenesis. They coincide with an increase in cis-regulatory regions harboring metazoan TF binding motifs, as well as an increase in the expression of metazoan-specific genes. Changes in chromatin state and gene expression in Amphimedon suggest the conservation of distal enhancers, dynamically silenced...
  6. ...with the midblastula transition (MBT). Nanog was reported to contribute to the establishment of accessible chromatin and is involved in regulatory processes during ZGA (Lee et al. 2013; Liu et al. 2018; Veil et al. 2019; Pálfy et al. 2020). With the reliability of the FitCUT&RUN method demonstrated, in this study, we...
  7. ...settings.ResultsBivalent chromatin does not poise genes for rapid activationTo assess whether bivalent chromatin represents a distinct epigenetic state and/or a regulatory mechanism, we investigated genes with bivalently marked promoters in pluripotent human embryonic stem cells (ESCs) (Supplemental Table...
  8. ...for analysis of genomic imprinting, gene function, and epigenetic dynamics (Dean et al. 2001a). However, species-specific epigenetic regulation does exist (Haaf 2006). Major epigenetic reprogramming during preimplantation development differs across mammalian species (Beaujean et al. 2004; Fulka et al. 2004...
  9. ...al. 2016; Wu and Knudson 2018). Some genes that emerge de novo not only provide new functions, but have even become essential to the species in which they emerged. For example, the human-specific de novo gene ESRG is required for the maintenance of pluripotency in human naive stem cells (Wang et al...
  10. ...with the dynamic changes in transcription and epigenetic marks during early development is not fully understood (Schübeler et al. 2002; MacAlpine et al. 2004; Hiratani et al. 2009). Furthermore, the replication timing program correlates with chromatin conformation, as early and late replicating regions correspond...
