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...

MetabolomicsWe characterize the anti-phage function of a type IV TA system, ShosTA toxin-antitoxin system provides phage defense via DNA damage and repair
Widespread in bacteria and archaea, Toxin-antitoxin (TA) systems have been recently demonstrated to function in phage defense. Here we characterize the anti-phage function of a type IV TA system, ShosTA. Using structural and biochemical approaches, we show that ShosT couples phosphoribosyltransferas...

ProteomicsSkin cancer-associated S. aureus downregulates DNA repair mechanisms, and promotes oxidative stress and DNA damage in human keratinocytes
Actinic keratoses (AK) are premalignant lesions common on photo-damaged skin that, over time, can progress to squamous cell carcinoma (SCC). A high bacterial load of Staphylococcus aureus is associated with AK and SCC but it is unknown whether this has a direct impact on skin cancer development. To ...

TranscriptomicsCPD-seq mapping of UV damage formation and repair in yeast
UV-induced DNA lesions are an important contributor to mutagenesis and cancer, but it is not fully understood how the chromosomal landscape influences UV lesion formation and repair. We have used a novel high-throughput sequencing method to precisely map UV-induced cyclobutane pyrimidine dimers (CPD...

TranscriptomicsRoles for the Transcription Elongation Factor NusA in Both DNA Repair and Damage Tolerance Pathways in Escherichia coli
Here we report our observations that have led us to propose that the transcription elongation factor NusA promotes a novel class of transcription-coupled repair (TCR) in addition to its previously proposed role in recruiting translesion synthesis (TLS) DNA polymerases to gaps encountered during tran...

ProteomicsPDHE1α, PARylation, Acetyl-CoA, Acetylation, Histones, DNA damage repair
Chromatin relaxation is a prerequisite step that allows the DNA repair machinery to access double-strand breaks (DSBs), and local histones around the DNA breaks suffer from prompt acetylation changes. However, an intriguing question remains as to where the large demands of acetyl-CoA is precisely pr...

MetabolomicsUrinary metabolomics reveals kynurenine pathway perturbation in newborns with transposition of great arteries after surgical repair

INTRODUCTION: Transposition of the great arteries (TGA) is a cyanotic congenital heart defect that requires surgical correction, with the use of cardiopulmonary-bypass (CPB), usually within 3 weeks of life. The use of CPB in open heart surgery results in brain hypoperfu...

ProteomicsInhibition of nuclear PTEN tyrosine phosphorylation enhances glioma radiation sensitivity through attenuated DNA repair
Glioblastoma (GBM) is the most lethal brain tumour that occurs in adults and treatment for GBM has been largely unsuccessful. Ionizing radiation (IR) and chemotherapeutic agents are employed as standard of care treatment for GBM patients and both result in DNA damage. Previous data identified phosph...

TranscriptomicsSynthetic circuit identifies subpopulations with sustained memory of DNA damage
Differential responses to stimuli can affect how cells succumb to disease. In yeast, DNA damage can create heterogeneous responses. To delineate how a response contributes to a cell's future behavior, we constructed a transcription-based memory circuit that detects DNA repair to isolate subpopulatio...

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...
