Cooperation of the ATM and Fanconi Anemia/BRCA Pathways in Double-Strand Break End Resection

open access: yesCell Reports, 2020
Summary: Cells deficient in ataxia telangiectasia mutated (ATM) are hypersensitive to ionizing radiation and other anti-cancer agents that induce double-strand DNA breaks. ATM inhibitors may therefore sensitize cancer cells to these agents.

Suppression of isoprenylcysteine carboxylmethyltransferase compromises DNA damage repair

open access: yesLife Science Alliance, 2021
Inhibition of isoprenylcysteine carboxylmethyltransferase reduces cancer cells’ ability to repair DNA damage by suppressing the expression of critical DNA damage repair pathway genes, hence increasing their vulnerability to DNA damaging insults such as ...

Fatty acid oxidation facilitates DNA double-strand break repair by promoting PARP1 acetylation

open access: yesCell Death and Disease, 2023
DNA repair is a tightly coordinated stress response to DNA damage, which is critical for preserving genome integrity. Accruing evidence suggests that metabolic pathways have been correlated with cellular response to DNA damage.

Phosphorylation-mediated interactions with TOPBP1 couple 53BP1 and 9-1-1 to control the G1 DNA damage checkpoint

open access: yeseLife, 2019
Coordination of the cellular response to DNA damage is organised by multi-domain ‘scaffold’ proteins, including 53BP1 and TOPBP1, which recognise post-translational modifications such as phosphorylation, methylation and ubiquitylation on other proteins ...

Multi-Faceted Roles of ERCC1-XPF Nuclease in Processing Non-B DNA Structures

open access: yesDNA, 2022
Genetic instability can result from increases in DNA damage and/or alterations in DNA repair proteins and can contribute to disease development. Both exogenous and endogenous sources of DNA damage and/or alterations in DNA structure (e.g., non-B DNA) can

RanBP2-Mediated SUMOylation Promotes Human DNA Polymerase Lambda Nuclear Localization and DNA Repair [PDF]

open access: yes, 2020
Cellular DNA is under constant attack by a wide variety of agents, both endogenous and exogenous. To counteract DNA damage, human cells have a large collection of DNA repair factors. Among them, DNA polymerase lambda (Polλ) stands out for its versatility,

BRCT domains of the DNA damage checkpoint proteins TOPBP1/Rad4 display distinct specificities for phosphopeptide ligands

open access: yeseLife, 2018
TOPBP1 and its fission yeast homologue Rad4, are critical players in a range of DNA replication, repair and damage signalling processes. They are composed of multiple BRCT domains, some of which bind phosphorylated motifs in other proteins. They thus act

Targeting DNA damage response as a potential therapeutic strategy for head and neck squamous cell carcinoma

open access: yesFrontiers in Oncology, 2022
Cells experience both endogenous and exogenous DNA damage daily. To maintain genome integrity and suppress tumorigenesis, individuals have evolutionarily acquired a series of repair functions, termed DNA damage response (DDR), to repair DNA damage and ...

DNA Damage, Repair, and Diseases [PDF]

open access: yesBioMed Research International, 2002
DNA is the essential carrier of genetic information in all living cells. How is the huge amount of DNA in organisms from bacteria to humans maintained and protected from the ravages of noxious agents in the environment? The chemical stability of the DNA molecule is not unusually great, DNA undergoes several types of spontaneous modifications, and it ...

Elevated Level of DNA Damage and Impaired Repair of Oxidative DNA Damage in Patients with Recurrent Depressive Disorder [PDF]

open access: yes, 2015
Background: Depressive disorder (DD), including recurrent DD (rDD), is a severe psychological disease, which affects a large percentage of the world population.
