  1. ...-translational modifications, play a crucial role in regulating programs integral to a cell's identity, like gene expression and DNA replication. However, the transcriptional, chromatin, and replication timing profiles of adult stem cells in vivo remain poorly understood. Containing germline stem cells (GSCs) and somatic cyst...
  2. ...using TRIzol, and designated as one biological replicate. DNA from the thoraxes of 446 the corresponding honey bees in each biological replicate was extracted. For the second 447 batch of 12 GF and CV bees, the head of each bee was set as one biological replicate and 448 used for RNA sequencing...

  3. ..., and the complete training protocol, enabling exact replication of the model architectures and experimental results.Feature encoding schemesMore than 24 common feature encoding schemes are widely used in epigenetic site prediction. In the work of EpiTEAmDNA, Li et al. (2023) demonstrated that 10 feature encoding...
  4. ...shared the same dynamic timescales. To simulate chromatin, we modeled 2.5 Mb of DNA as a 50-nm fiber with monomers of size 2.5 kb (Methods). Altogether, in our linked 1D extrusion and 3D polymer simulations, loop extruders can sequentially encounter and bypass dynamic barriers with corresponding impacts...
  5. ...affinities following from differences in RNA Polymerase II kinetics owing to local GC content.Alternative splicing occurs predominantly cotranscriptionally and thus takes place in close proximity to the DNA from which the transcript originated (Reimer et al. 2021). Beyond being impacted by transcription...
  6. ...the molecular mechanisms that control this process. Recent studies indicate that DNA N6-adenine methylation (6mA) could be dynamically changing in response to external stimuli; however, its potential role in the regulation of cyst formation remains unknown. We used the ciliate Pseudocohnilembus persalinus...
  7. ...sorting with high-throughput sequencing. Essentially all IESs are excised within only one endoreplication round (32C to 64C), whereas TEs are eliminated at a later stage. We show that DNA elimination proceeds independently of replication. We defined four IES classes according to excision timing...
  8. ...State University, Tallahassee, Florida, 32306-4295, USA; 6Center for Genomics and Personalized Medicine, Florida State University, Tallahassee, Florida 32306, USA Corresponding authors: gilbert@bio.fsu.edu, tamer@cise.ufl.eduAbstractDNA replication occurs in a defined temporal order known...
  9. .... To test this, we profiled DNA replication timing in isogenic haploid and diploid ESCs. The greatest difference was the earlier replication of the X Chromosome in haploids, consistent with the lack of X-Chromosome inactivation. We also identified 21 autosomal regions that had delayed replication...
  10. ...catalyzing DNA demethylation (erasers). Investigation of DNA methyltransferases in Arabidopsis thaliana has revealed sequence context-specific activity for these enzymes: MET1 is responsible for maintaining mCG, being recruited to hemimethylated sites after replication (Finnegan et al. 1996; Ronemus et al...
