  1. ...for pseudogenes, lncRNAs, and protein-coding genes annotated with their epigenetic activity. To annotate these promoter regions with chromatin activity profiles across tissues, we leveraged EN-TEx epigenomic maps comprising chromatin immunoprecipitation sequencing (ChIP-seq) data for six histone modifications (i...

  2. ...activity may restrict CENH3 expansion and centromere formation in adjacent regions (Fig. 4B). Transcription of genes (Dt7AS: G15, G23) within these regions might hinder seeding and spreading of CENH3, prior to centromere establishment (Fig. 4B–D). To explore the epigenetic context before neocentromere...
  3. ...of and downstream from the D4Z4 array, for both A and B alleles (Supplemental Table S4). Additionally, we complemented this with guide RNAs designed to target a panel of FSHD2-associated genes (SMCHD1, DNMT3B, and LRIF1) (Supplemental Table S4), with a view to developing an all-in-one genetic and epigenetic...
  4. ...unclear. Leveraging advancements in single-cell genomics, this study utilizes single-nucleus multiome sequencing to capture transcriptomic and epigenetic profiles from 40,125 cells across the lifespan of the mouse substantia nigra. Our analysis pinpoints age-associated changes at a cell type...
  5. ...aging. These include changes in DNA methylation, histone modifications, chromatin remodeling, and noncoding RNAs. Collectively, such alterations disrupt gene regulatory networks, leading to transcriptional dysregulation, loss of cellular homeostasis, and increased vulnerability to age-related diseases...
  6. ...modifications like H3K9me2, which can be subsequently maintained independently of siRNAs. However, the of the clonally propagating duckweed Spirodela polyrhiza (Lemnaceae) has low levels of DNA methylation, very low expression of RdDM components, and near absence of 24 nt siRNAs. Moreover, some genes encoding...
  7. ...hypersensitivity), high nucleosomal turnover (e.g., high levels of rapid-turnover histones H2A.Z and H3.3), specific epigenetic markers (e.g., high ratio of H3K4me1 and H3K4me2 to H3K4me3, high ratio of 5hmC to 5mC, enrichment of H3K27ac), chromatin loops in direct contact with the core promoter (enrichment...

  8. ...pathways through modification of a protein–protein interface (PPI), and neofunctionalization. Therefore, we assessed each FIE using additional evidence to indicate its potential for neofunctionalization by (1) identifying whether the FIE gene was from a diverse CATH superfamily, (2) checking for paralogs...
  9. ...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...
  10. ...to changes in the 3D structure of gene loci which in turn leads to deregulation. If these simulations allow us to infer the pathway through which the CCND1 proto-oncogene becomes activated, they could be used to generate testable hypotheses to direct new experiments suggesting targets for therapeutic...
