  1. .... 2016), we initially speculated that H3K4me3 remodeling occurred upon transcriptional reactivation of the zygotic in the early embryo, which is initiated at the four-cell stage and gradually increases over the next several cell divisions before reaching steady-state levels (Robertson and Lin 2015...
  2. ...armigera, Polycomb group (PcG) proteins regulate PTTH production and prevent diapause entry through the control of H3K27me3 (Lu et al. 2013). By ovary-specific knockdown of histone mark writers and erasers, DiVito Evans et al. (2023) showed that H3K4me3 and H3K36me1 depletion promotes reproductive diapause...
  3. ..., B2 and B3 show features of heterochromatin, with enrichment of repressive histone marks (H3K27me3) and lamin B1. Compared with the other subcompartments, A0 and B0 are the least enriched in active and repressive histone marks, respectively, raising the interesting possibility that they could be more...
  4. ...A -wide survey reveals a diverse array of enhancers coordinates the Drosophila 1 innate immune response 2 3 Lianne B. Cohen1, 2, Tamara Hadzic2, 3, Caitlin Sauer1, 2, Julia R. Gibbs1, 2, Zeba Wunderlich1, 2, 3, 4 4* 5 1. Department of Biology, Boston University, Boston, MA 02215, USA 6 2...

  5. ...-mediated repression allows activation of ERV enhancers upon entry into meiosis. This regulatory feature is observed for independently evolved KZFPs and ERVs in mice and humans, suggesting evolutionary conservation in mammals. Further, we show that KZFP-targeted ERVs are underrepresented on the sex chromosomes...
  6. ...be contained in the spread of epigenetic modifications over a genomic locus. Large megabase-sized chromatin domains have been described for the repressive chromatin mark H3K9me3 in senescence cells spanning large chromosomal regions (Soufi et al. 2012) or activating H3K4me3 in mammalian oocytes (Dahl et al...
  7. ...was calculated as the percentage of CpG sites covered by H3K4me3 ChIP-seq peaks. (C) Enrichment of B cell ChIA-PET (Pol II) tags in tissue MHBs. The enrichment was tested using the R package LOLA, with the union of MHBs from all tissues as the background. (D) An example genomic track showing that chromatin...
  8. ...protein-coding gene sets. To define CGC1 genomic coordinates for sequences that either are shared with N2 (Supplemental Data File 10) or are unique to CGC1 (Supplemental Data File 11) to which genes or transcripts could be assigned, we aligned the two assemblies and identified uniquely aligned blocks...
  9. ...the exact coordinates of involved genomic segments and genes (Supplemental Table S2) whether the duplication or triplication of specific genes contribute to the phenotype remains unclear, as transcriptional activity and downstream effects were not assessed.We and others have previously shown that lr...
  10. ...,324,000–27,329,000) revealed overlapping CpG islands with H3K27me3 histone modification, which suggests that multiple genomic-feature elements and epigenetic regulators synergistically regulate PTK2B gene expression.Given that the mural and polar sublineages displayed a differential response to glucocorticoid exposure, we...
