  1. ..., a particular gene of interest (GOI) remains a persistent experimental and conceptual challenge. This gene-centric question is complicated by the multilayered regulatory environment in which each gene resides, comprising 3D chromatin structure, enhancer–promoter looping, DNA accessibility, histone modifications...

  2. ....v.razin@usa.net ↵ 12 These authors contributed equally to this work. Abstract Recent advances enabled by the Hi-C technique have unraveled many principles of chromosomal folding that were subsequently linked to disease and gene regulation. In particular, Hi-C revealed that chromosomes of animals...
  3. ...genes map to multiple chromosomes. Proc. Natl. Acad. Sci. 83 : 3185 – 3188 . Wang Z.-F., Krasikov, T. Frey, M.R. Wang, J. Matera, A.G. and Marzluff. W.F. 1996 . Characterization of the mouse histone gene cluster on chromosome 13: 45 histone genes in three patches spread over 1 Mb. Genome Res. (this...
  4. ...into the Notch signaling cascade. [Supplemental material is available online at http://www..org.] The Enhancer of split complex [E(spl)-C] ofDrosophilamelanogaster is a well characterized genetic locus containing 12 genes on chromosome 3R, most of which are to be effectors or modulators of Notch signaling. The E...
  5. ...is overexpressed (Supplemental Fig. S6C).H3K79 methylation protects euchromatin from the spread of silencingTo identify H3 and H4 histone residues involved in the limitation of Sir3 spreading, we set a genetic screen based on the Synthetic Gene Array (Dai and Boeke 2012). H3K79R was the sole histone point mutant...
  6. ...repeat-derived endo-siRNA mimics are sufficient to rescue Dcr-2-deficiency-induced defects in heterochromatin formation in interphase and chromosome segregation during mitosis, demonstrating that active retrotransposons are required for stable genetic inheritance.Eukaryotic s contain both gene...
  7. ...of almost equal height centered over the +1 and 1 nucleosomes, whereas H3K4me3 peaks asymmetrically over the +1 position. H4K16ac also spreads further into the gene body compared with H3K4me3, but its distribution differs from that of H3K36me3, a histone modification associated with the elongation...
  8. ...arm length drive telomere clustering An analysis of subtelomeric sequences of yeast chromosomes indicated that they fall into seven subgroups reflecting the presence of subtelomeric gene families (Supplemental Fig. 3; see also www.nottingham.ac.uk/genetics/louis ). Given that this number agreed...
  9. ...genes. Histone H3 lysine 4 trimethylation (H3K4me3) is enriched at the 59 ends of active genes. Clusters 1 and 3 correspond to methylated CpGis with different methylation profiles between stages. A few of these are located in introns of actively transcribed genes (RNAPII-positive, RNA...
  10. ...-VNTR-Alu) families can still actively spread through the , and new insertions cause variation between individuals in the form of presence/absence TE-insertional polymorphisms (Kazazian et al. 1988; Batzer et al. 1991; Brouha et al. 2003; Ostertag et al. 2003). TEs can alter gene regulation in the locus in which...
