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 ...

TranscriptomicsTopoisomerase function in E. coli replication fork movement
Analysis of topoisomerase function in bacterial replication fork movement: use of DNA microarrays. We used DNA microarrays of the Escherichia coli genome to trace the progression of chromosomal replication forks in synchronized cells. We found that both DNA gyrase and topoisomerase IV (topo IV) prom...

TranscriptomicsAvoiding chromosome pathology when replication forks collide
Chromosome duplication normally initiates via the assembly of replication fork complexes at defined origins. DNA synthesis by any one fork is thought to cease when it meets another travelling in the opposite direction, at which stage the replication machinery may simply dissociate before the nascent...

TranscriptomicsInvolvement of a chromatin remodeling complex in damage tolerance during DNA replication
ATP-dependent chromatin remodeling complexes have been shown to participate in DNA replication in addition to transcription and DNA repair. However, the mechanisms of their involvement in DNA replication remain unclear. Here, we reveal a specific function of the yeast INO80 chromatin remodeling comp...

TranscriptomicsTop1 and Top2-mediated replication fork integrity
DNA topoisomerases solve topological problems during chromosome metabolism. We investigated where and when Top1 and Top2 are recruited on replicating chromosomes and how their inactivation affects fork integrity and DNA damage checkpoint activation. We show that, in the context of replicating chroma...

ProteomicsDynamics of de novo heterochromatin assembly and disassembly at replication forks ensures fork stability
Chromatin is dynamically reorganized when DNA replication forks are challenged. However, the process of epigenetic reorganization and its implication for fork stability is poorly understood. Here, we discover a checkpoint regulated cascade of chromatin signaling that activates 5 the histone methyl...

ProteomicsSystem-wide analysis of SUMOylation dynamics in response to replication stress reveals novel SUMO target proteins and acceptor lysines relevant for genome stability
Genotoxic agents can cause replication fork stalling in dividing cells due to DNA lesions, eventually leading to replication fork collapse when the damage is not repaired. Small Ubiquitin-like Modifiers (SUMOs) are known to counteract replication stress, nevertheless, only a small number of relevant...

TranscriptomicsGenome-wide replication analysis of a yeast eco1 mutant by deep sequencing.
Eco1 is the acetyltransferase that establishes sister-chromatid cohesion during DNA replication. Budding yeast with an eco1 mutation that genocopies Roberts syndrome displaysreduced ribosomal DNA (rDNA) transcription and a transcriptional signature of starvation. Weshow that deleting FOB1, a gene en...

ProteomicsMetalloprotease SPRTN/DVC1 Orchestrates Replication-Coupled DNA-Protein Crosslink Removal
Cytotoxicity of DNA-protein crosslinks (DPCs) is ascribed largely to their ability to block the progression of DNA replication fork. DPCs are frequently occurring in cells, either as a consequence of metabolism or exogenous agents. The mechanism of DPCs removal is not completely understood. Here, we...
