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 ...

TranscriptomicsTranscription Initiation Activity Sets Replication Origin Efficiency in Mammalian Cells
Genomic mapping of DNA replication origins (ORIs) in mammals provides a powerful means for understanding the regulatory complexity of our genome. Here we combine a genome-wide approach to identify preferential sites of DNA replication initiation at 0.4% of the mouse genome with detailed molecular an...

TranscriptomicsComplex patterns of accessibility discriminate sites of PcG repression, H4K16 acetylation and replication initiation
Full title: Complex patterns of genome accessibility discriminate sites of PcG repression, H4K16 acetylation and replication initiation Histone modifications have been proposed to regulate gene expression in part by modulating DNA accessibility and higher-order chromatin structure. However, there i...

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...

TranscriptomicsReplication initiation sites in cancer cells
Reads from massively parallel sequencing of RNA primed, short nascent strands from asynchronously growing cancer cells (K562, MCF7). Newly replicated DNA was isolated based on size (400-800 bp) and the presence of a short RNA stretch at the 5' end using lambda exonuclease. Purified nascent strands w...

TranscriptomicsRif1 regulates initiation timing of late replication origins throughout the S. cerevisiae genome [ChIP-Seq]
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-...

TranscriptomicsSeparation of DNA replication from the assembly of break-competent meiotic chromosomes
The meiotic cell division reduces the chromosome number from diploid to haploid to form gametes for sexual reproduction. Although much progress has been made in understanding meiotic recombination and the two meiotic divisions, the processes leading up to recombination, including the prolonged pre-m...

GenomicsPost-licensing specification of eukaryotic replication origins by facilitated Mcm2-7 sliding along DNA
Eukaryotic genomes are replicated from many origin sites that are licensed by the loading of inactive double hexamers of the replicative DNA helicase, Mcm2-7. How eukaryotic origin positions are specified remains elusive. Here we show that, contrary to the bacterial paradigm, eukaryotic origins are ...
