TranscriptomicsAbnormal Developmental Control of Replication Timing Domains in Pediatric Acute Lymphoblastic Leukemia
Abnormal replication timing has been observed in cancer but no study has comprehensively evaluated this misregulation. We generated genome-wide replication timing profiles for pediatric leukemias from 17 patients and 3 cell lines, as well as normal B and T cells. Non-leukemic EBV-transformed lymphob...

TranscriptomicsReplication Timing Reveal An Epigenetic Commitment To Differentiation Prior To Germ Layer Specification (WG_CGH, RT)
Differentiation of mouse embryonic stem cells (mESCs) is accompanied by global changes in replication timing. To elucidate this reorganization process and explore its potential impact on mouse development, we constructed genome-wide replication-timing profiles of 15 independent mouse cell types repr...

TranscriptomicsGenome-wide connection between DNA methylation and DNA replication timing
DNA methylation and DNA replication timing were examined across a variety of human tissues and cell lines, applying microarray-based techniques. The analyses revealed that late-replicating DNA was demethylated compared to the methylation of early-replicating regions. DNA methylation: Epstein-Barr-Vi...

MetabolomicsThe pyruvate kinase, a metabolic sensor powering glycolysis, drives the metabolic control of DNA replication

BACKGROUND: In all living organisms, DNA replication is exquisitely regulated in a wide range of growth conditions to achieve timely and accurate genome duplication prior to cell division. Failures in this regulation cause DNA damage with potentially disastrous consequences ...

TranscriptomicsGenome-wide Profiling of DNA Replication Timing in pombe.
DNA replication is initiated at multiple sites or origins enriched with AT-rich sequences at various times during the S-phase. While current studies of genome-wide DNA replication profiles have focused on the timing of replication and the location of origins, the efficiency of replication/firing at...

TranscriptomicsGenome-Wide Dynamics of Replication Timing Revealed by In Vitro Models of Mouse Embryogenesis (Expression)
Differentiation of mouse embryonic stem cells (mESCs) is accompanied by changes in replication timing. To explore the relationship between replication timing and cell fate transitions, we constructed genome-wide replication-timing profiles of 22 independent mouse cell lines representing 10 stages of...

TranscriptomicsRif1 regulates the replication timing domains on the human genome
DNA replication is spatially and temporally regulated during S-phase. DNA replication timing is established in early G1-phase at a point referred to as TDP (timing decision point). We show that Rif1 (Rap1-interacting-factor1), originally identified as a telomere binding factor in yeast, is a critica...

TranscriptomicsRif1 regulates initiation timing of late replication origins throughout the S. cerevisiae genome [array]
Chromosomal DNA replication involves the coordinated activity of hundreds to thousands of replication origins. Individual replication origins are subject to epigenetic regulation of their activity during S-phase, resulting in differential efficiencies and timings of replication initiation during S-...

TranscriptomicsReplication timing of siRNA control and siRNA PolQRKO cells
The human A-family DNA polymerase M-NM-8 (Pol q) is a large, multidomain enzyme whose physiological function is still unclear despite its in vitro translesion synthesis capacity in front of DNA damage and its involvement in some features of DNA repair after external stress. Here we present evidence ...
