  1. ...-translational modifications, play a crucial role in regulating programs integral to a cell's identity, like gene expression and DNA replication. However, the transcriptional, chromatin, and replication timing profiles of adult stem cells in vivo remain poorly understood. Containing germline stem cells (GSCs) and somatic cyst...
  2. ..., Luzi L, Banfi S, Segalla S, Cesaroni M, Mendoza-Maldonado R, Giacca M, Pelicci PG. 2013. Genome-wide mapping of human DNA-replication origins: levels of transcription at ORC1 sites regulate origin selection and replication timing. Genome Res 23: 1–11. doi:10.1101/gr.142331.112 ↵Desprat R, Thierry...
  3. ...in measureable changes in DNA replication origin usage. To identify sites of DNA replication initiation, previous studies have used newly replicated nascent DNA strands that are size selected for those sufficiently short to lie near to origins of replication but not so short that they include Okazaki fragments...
  4. ...in the Drosophila genome were static across all cell lines; however, a small subset of domains was dynamic and exhibited differences in replication timing between the cell lines. Both origin selection and activation contribute to defining the DNA replication program. Our results suggest that static early and late...
  5. ...transcription compared to non-ORC-bound and nonreplicated ARSs (nr-ARSs) (Supplemental Fig. S4E; Eaton et al. 2010).View larger version: In this window In a new window Figure 3. Natural pervasive transcription correlates with timing/efficiency and specific chromatin features of replication origins. (A) Metagene...
  6. ...Genome-wide mapping of nuclear mitochondrial DNA sequences links DNA replication origins to chromosomal double-strand break formation in Schizosaccharomyces pombe Sandrine Lenglez 1 , Damien Hermand 2 and Anabelle Decottignies 1 , 3 1 Catholic...
  7. ..., whereas dormant origins are poorly conserved. Second, we generated genome-wide replication profiles for each of these species and discovered that the temporal order of genome replication is highly conserved. Therefore, active origins are not only conserved in location, but also in activation time. Only...
  8. ...-expressed with DONSON were again strikingly enriched for genes coding for components of the DNA replication machinery, including (1) the ORC1 origin recognition complex subunit 1, (2) CDC6, which together with CDT1 loads the MCM2-7 replication helicase onto replication origins, (3) GINS1, a component of the active CMG...
  9. ...be repressed, we examined regions selectively under-replicated in Drosophila polytene salivary glands, and found they are transcriptionally silent and enriched for the repressive H3K27me3 mark. In the first -wide analysis of binding of the origin recognition complex (ORC) in a differentiated metazoan tissue...
  10. ...be attributed to the differential timing of firing of DNA initiation sites or DNA replication origins within the . Replication origins initiate DNA replication with the help of the prereplication complex (pre-RC), two major components of which are the origin recognition complex (Orc1-6) and the minichromosome...
