  1. ...size ranging from three to 11 shown for each of the three breast cancer stages. Asterisks indicate significant differences (see Supplemental Table S10). Inset illustrates how “TAD cliques” are identified from the statistically significant Hi-C interactions between TADs. (B) Example region on Chromosome...
  2. ..., Davoli and colleagues published a new system for targeted chromosome missegregation (Bosco et al. 2023). In this approach, called KaryoCreate, catalytically inactive dCas9 is used to target a checkpoint-deficient kinetochore protein to a specific mammalian centromere (Fig. 3A). The mutant kinetochore...
  3. ...Cell-type- and chromosome-specific chromatin landscapes and DNA replication programs of Drosophila testis tumor stem cell–like cells Jennifer A. Urban1, Daniel Ringwalt1, John M. Urban2,3, Wingel Xue1,5, Ryan Gleason1, Keji Zhao4 and Xin Chen1,2 1Department of Biology, The Johns Hopkins University...
  4. ...et al. 2018).Constitutively active ERBS exhibited higher chromatin accessibility in breast tumors than both induced and inactive ERBS (Supplemental Fig. S2A). Chromatin at induced ERBS was largely inaccessible in ESR1-negative tumors and became accessible only in ESR1-positive tumors. In contrast...
  5. ...and guided the development of HER2-targeted therapies (Sørlie et al. 2001; Prat et al. 2017).HER2-positive breast cancers, accounting for ∼20% of all breast cancers, are characterized by the overexpression or amplification of the HER2 gene (Wolff et al. 2013). Located on Chromosome 17q12, the HER2...
  6. ...inactivation (XCI) is a dosage-compensation mechanism equalizing the expression of the majority of X-linked genes between males and females (Van den Veyver 2001). In 46, XX females, one X Chromosome is chosen stochastically as the inactive X (Xi) in a small number of cells early in embryonic development...
  7. ...binding, which is associated with affected expression of the genes they control.DiscussionBreast cancer is a heterogenous disease, with clearly distinct inter-tumor differences on subtype, aggressiveness, and, ultimately, patient prognostication. Here, we show that on epigenetic scale, substantial inter...

  9. ...X Chromosome silencing in mammals (Do Kim et al. 2006; Donohoe et al. 2007; Jeon and Lee 2011; Makhlouf et al. 2014; Chen et al. 2016). In the context of mammalian X inactivation, YY1 binding is regulated by the differences in the epigenetic landscape between the active and inactive X in females...
  10. ...is a dosage compensation mechanism in which one of the two X chromosome copies in females is transcriptionally inactivated ( Lyon 1961 ). The inactive chromosome is randomly chosen and subsequently clonally maintained through an epigenetic mechanism that involves coating of the chromosome by the noncoding RNA...
