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 ...

MetabolomicsMetabolic responses induced by DNA damage and poly (ADP-ribose) polymerase (PARP) inhibition in MCF-7 cells
Genomic instability is one of the hallmarks of cancer. Several chemotherapeutic drugs and radiotherapy induce DNA damage to prevent cancer cell replication. Cells in turn activate different DNA damage response (DDR) pathways to either repair the damage or induce cell death. These DDR pathways also e...

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...

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...

TranscriptomicsAccumulation of sumoylated Rad52 in checkpoint mutants perturbed in DNA replication
Checkpoints are cellular surveillance and signaling pathways that regulate responses to DNA damage and perturbations of DNA replication. Here we show that high levels of sumoylated Rad52 are present in the mec1 sml1 and rad53 sml1 checkpoint mutants exposed to DNA damaging agents such as methyl meth...

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...

ProteomicsProteomics reveals dynamic assembly of repair complexes during bypass of DNA cross-links part 2 of 2: AP-MS DATA (QUBIC)
DNA interstrand crosslinks (ICLs) block replication fork progression by inhibiting DNA strand separation. Repair of ICLs requires sequential incisions, translesion DNA synthesis, and homologous recombination, but the full set of factors involved in these transactions remains unknown. Here we establi...
