ATM Localization and Heterochromatin Repair Depend on Direct Interaction of the 53BP1-BRCT2 Domain with γH2AX

open access: yesCell Reports, 2015
53BP1 plays multiple roles in mammalian DNA damage repair, mediating pathway choice and facilitating DNA double-strand break repair in heterochromatin. Although it possesses a C-terminal BRCT2 domain, commonly involved in phospho-peptide binding in other

Histone post-translational modification and the DNA damage response

open access: yesGenes and Diseases, 2023
DNA is highly vulnerable to spontaneous and environmental timely damage in living cells. DNA damage may cause genetic instability and increase cancer risk if the damages are not repaired timely and efficiently.

Nuclear rupture at sites of high curvature compromises retention of DNA repair factors. [PDF]

open access: yes, 2018
The nucleus is physically linked to the cytoskeleton, adhesions, and extracellular matrix-all of which sustain forces, but their relationships to DNA damage are obscure. We show that nuclear rupture with cytoplasmic mislocalization of multiple DNA repair

Oxidative stress-induced DNA damage and repair in human peripheral blood mononuclear cells: protective role of hemoglobin. [PDF]

open access: yesPLoS ONE, 2013
BACKGROUND:DNA repair is a cellular defence mechanism responding to DNA damage caused in large part by oxidative stress. There is a controversy with regard to the effect of red blood cells on DNA damage and cellular response.

TDP2 promotes repair of topoisomerase I-mediated DNA damage in the absence of TDP1 [PDF]

open access: yes, 2012
The abortive activity of topoisomerases can result in clastogenic and/or lethal DNA damage in which the topoisomerase is covalently linked to the 3'- or 5'-terminus of a DNA strand break. This type of DNA damage is implicated in chromosome translocations

The Ability of Cyanobacterial Cells to Restore UV-B Radiation Induced Damage to Photosystem II is Influenced by Photolyase Dependent DNA Repair [PDF]

open access: yes, 2013
Damage of DNA and Photosystem-II are among the most significant effects of UV-B irradiation in photosynthetic organisms. Both damaged DNA and Photosystem-II can be repaired, which represent important defense mechanisms against detrimental UV-B effects ...

H3K36me3, message from chromatin to DNA damage repair

open access: yesCell & Bioscience, 2020
Histone marks control many cellular processes including DNA damage repair. This review will focus primarily on the active histone mark H3K36me3 in the regulation of DNA damage repair and the maintenance of genomic stability after DNA damage.

DNA damage and repair following traumatic brain injury

open access: yesNeurobiology of Disease, 2021
Traumatic brain injury (TBI) is known to promote significant DNA damage irrespective of age, sex, and species. Chemical as well as structural DNA modification start within minutes and persist for days after TBI.

Repair, abort, ignore? Strategies for dealing with UV damage [PDF]

open access: yes, 2011
DNA repair is a prominent member of the nuclear transactions triad (replication, transcription, and repair). Sophisticated mechanisms govern the cellular process of decision-making (to repair or not to repair, to proceed with cell cycle or not and ...

Specialized interfaces of Smc5/6 control hinge stability and DNA association

open access: yesNature Communications, 2017
Structural Maintenance of Chromosomes (SMC) complexes maintain genome integrity by regulating the segregation of chromosomes. Here, Altet al. describe the structure of the heterodimeric Smc5/6-hinge from fission yeast and define functional features ...
