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 ...

MetabolomicsCell overgrowth potentiates osmotic and replication stresses to promote p38/p53/p21-dependent senescence
Abnormal increases in cell size are associated with senescence and cell cycle exit. The mechanisms by which overgrowth primes cells to withdraw from the cell cycle remain unknown. We address this question using CDK4/6 inhibitors, which arrest cells in G0/G1 and are licensed to treat advanced HR+/HER...

ProteomicsProteome-wide analysis of SUMO2 targets in response to pathological DNA replication stress in human cells
SUMOylation is a form of post-translational modification involving covalent attachment of SUMO (Small Ubiquitin-like Modifier) polypeptides to specific lysine residues in the target protein. In human cells, there are four SUMO proteins, SUMO1–4, with SUMO2 and SUMO3 forming a closely related subfami...

MetabolomicsCDK4/6 inhibitor-mediated cell overgrowth triggers an osmotic stress response and chronic p38MAPK activation to promote long-term cell cycle arrest

Cell size and the cell cycle are intrinsically coupled and abnormal increases in cell size are associated with senescence and permanent cell cycle arrest. The mechanism by which overgrowth primes cells to withdraw from the cell cycle remains unknown. We investigate this here using CDK4/6 inhibito...

MetabolomicsTrehalose accumulation strategy enhancing cold stress response in Telenomus remus, a dominant egg parasitoid of Spodoptera frugiperda

Telenomus remus, an egg parasitoid capable of penetrating multi-layered egg masses, has emerged as a promising candidate for the biological control of Spodoptera frugiperda. Nevertheless, our prior investigations have uncovered that its limited cold tolerance represents a critical bottleneck in m...

TranscriptomicsMre11 suppresses replication stress and gene amplification proficiency
Gene amplification, copy-number increases of particular genes and surrounding genomic segments, promotes cancer progression and acquired therapy resistance. Thus, understanding genetic traits that confer gene amplification proficiency is important. The primary step for gene amplification is sponta...

ProteomicsATR inhibition rewires cellular signaling networks in response to pathologic replication stress
DNA replication stress is the major cause of genomic instability in human cells. The ataxia telangiectasia and Rad3-related kinase (ATR) plays an essential role in the cellular response to replication stress and inhibition of ATR has emerged as therapeutic strategy for the treatment of cancer. Howev...

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...

TranscriptomicsImpaired DNA damage metabolism promotes autoimmunity in TREX1 deficiencyÂ
Constitutive low level DNA damage is linked to innate immune activation. Hierarchical clustering of over 9000 transcripts revealed remarkably similar profiles in a patient with lupus erythematosus and a patient with AGS with up-regulation of genes involved in DNA damage signaling, p53-inducible gene...

TranscriptomicsChromosome length influences replication-induced topological stress
During chromosome duplication the parental DNA molecule becomes over-wound, or positively supercoiled, in the region ahead of the advancing replication fork. To allow fork progression this superhelical tension has to be removed by topoisomerases, which operate by introducing transient DNA breaks. Po...
