Inactivation of nuclear GSK3β by Ser389 phosphorylation promotes lymphocyte fitness during DNA double-strand break response

open access: yesNature Communications, 2016
Double stranded DNA breaks are generated during rearrangements of lymphocyte antigen receptors. Here the authors show that the DNA breaks induce phosphorylation of nuclear GSK3β at Ser389/Thr390, protecting the activated lymphocytes from necroptosis ...

Reparative properties of human glioblastoma cells after single exposure to a wide range of X-ray doses

open access: yesFrontiers in Oncology, 2022
Radiation therapy induces double-stranded DNA breaks in tumor cells, which leads to their death. A fraction of glioblastoma cells repair such breaks and reinitiate tumor growth.

hSSB1 interacts directly with the MRN complex stimulating its recruitment to DNA double-strand breaks and its endo-nuclease activity [PDF]

open access: yes, 2013
hSSB1 is a recently discovered single-stranded DNA binding protein that is essential for efficient repair of DNA double-strand breaks (DSBs) by the homologous recombination pathway.

High salt and DNA double-strand breaks [PDF]

open access: yesProceedings of the National Academy of Sciences, 2011
High-salt environments are often toxic to mammalian cells; however, some types, such as murine inner medullary collecting duct cells, are normally exposed to high-salt media. The IMCD3 cell line, derived from this mouse kidney cell type, is able to survive and even proliferate under high-salt conditions after a short period of adaptation (1 ...

PAXX promotes KU accumulation at DNA breaks and is essential for end-joining in XLF-deficient mice

open access: yesNature Communications, 2017
Non-homologous end-joining is the key pathway for repairing double-stranded DNA breaks in mammalian cells. Here the authors show that PAXX promotes the accumulation of KU at DNA breaks and is essential for end-joining in cells lacking XLF.

Sliding to the rescue of damaged DNA

open access: yeseLife, 2012
Single-molecule imaging experiments have shed new light on the methods used by the enzyme RecA to align single- and double-stranded DNA so that double-strand breaks can be repaired.

Reciprocal regulation of RIG-I and XRCC4 connects DNA repair with RIG-I immune signaling

open access: yesNature Communications, 2021
The RNA-sensing pathway has been associated with type I interferon (IFN) production induced by DNA damaging agents. Here the authors reveal that RIG-I, a cytosolic RNA sensor that recognizes RNA virus and initiates IFN signaling, is recruited to double ...

A moonlighting metabolic protein influences repair at DNA double-stranded breaks. [PDF]

open access: yes, 2015
Catalytically active proteins with divergent dual functions are often described as 'moonlighting'. In this work we characterize a new, chromatin-based function of Lys20, a moonlighting protein that is well known for its role in metabolism.

Nucleolar responses to DNA double-strand breaks [PDF]

open access: yesNucleic Acids Research, 2015
Maintenance of cellular homeostasis is key to prevent transformation and disease. The cellular response to DNA double-strand breaks, primarily orchestrated by the ATM/ATR kinases is one of many mechanisms that serve to uphold genome stability and homeostasis.

Reprogramming the mechanism of action of chlorambucil by coupling to a G-quadruplex ligand. [PDF]

open access: yes, 2014
The nitrogen mustard Chlorambucil (Chl) generates covalent adducts with double-helical DNA and inhibits cell proliferation. Among these adducts, interstrand cross-links (ICLs) are the most toxic, as they stall replication by generating DNA double strand ...
