  1. ...@cs.duke.eduAbstractEpigenetic mechanisms contribute to gene regulation by altering chromatin accessibility through changes in transcription factor (TF) and nucleosome occupancy across the . Despite numerous studies focusing on changes in gene expression, the intricate chromatin-mediated regulatory code remains largely uncharted...
  2. ...; Mattei et al. 2022; Shang and He 2022). Histone methylation, central to defining chromatin states, distinguishes transcriptionally active euchromatin from repressive heterochromatin. Histone methylation occurs at specific lysine residues of histones H3, H4, and H2B, including H3K4, H3K9, H3K27, H3K36, H4...
  3. ...is thought to be a key contributor to their differentiation potential. However, its precise roles in in vivo stem-cell systems remain to be fully elucidated.The Drosophila male germline is a well-established model for studying stem-cell biology with well-defined cell lineages and differentiation programs...
  4. ..., morphology, and disease susceptibility. We explore the limitations of current data sets for variant interpretation, tradeoffs between sequencing strategies, and the burgeoning role of long-read s for capturing structural variants. In addition, we consider how large-scale collections of whole- sequence data...
  5. ...transcriptional changes. To identify cis-regulatory changes that underlie anemia-specific gene expression and cellular responses, we analyzed chromatin accessibility in populations of cells enriched for red blood cell precursors isolated from mice at a range of time points after anemia induction. Early...
  6. ...per sample, along with a computational tool for designing large-scale microsatellite panels. Our method addresses the greatest challenge for microsatellite profiling—“stutter” artifacts—with a low-temperature hybridization capture that significantly reduces these artifacts. We also developed...
  7. ...organism Encyclopedia of Regulatory Networks) consortia to systematically assay TF binding events in vivo in two major model organisms, Drosophila melanogaster (fly) and Caenorhabditis elegans (worm). These data sets comprise 605 TFs identifying 3.6 M sites in the fly and 356 TFs identifying 0.9 M sites...
  8. ...in incomplete knockdown and can suffer from off-target effects, which complicate interpretation of transcriptional changes.Genome editing approaches, such as CRISPR–Cas9-mediated knockout (Nakamura et al. 2021), enable permanent removal of a TF. Knockouts are powerful for defining essential regulatory roles...
    OPEN ACCESS ARTICLE
  9. ..., demonstrating an unprecedented putative cis-regulatory role of Helitrons in Drosophila. Differential expression analysis between species with different preferred hosts reveals divergence in gene expression in heads and larvae. Although TEs’ presence does not affect overall gene expression, we observe 6...
  10. ...of chromatin looping (Davidson et al. 2019; Gabriele et al. 2022). An integrated analysis of stripes with genomic and epigenomic features at a -wide scale also shows vast potential in understanding the cooperation between regulatory elements in 3D space (Barrington et al. 2019; Kraft et al. 2019; Zhang et al...
