Base excision repair is the major pathway for the repair of oxidative DNA damage in human cells that is initiated by a damage-specific DNA glycosylase. In human cells, the major DNA glycosylases for the excision of oxidative base damage are

Clustered DNA lesions, possibly induced by ionizing radiation, constitute a trial for repair processes. Indeed, recent studies suggest that repair of such lesions may be compromised, potentially leading to the formation of lethal double-strand breaks (DSBs). A complex multiply damaged

Adipose-tissue derived mesenchymal stem cells (AT-MSCs) are a promising tool for use in cell-based therapies. However, in vitro expansion is required to obtain clinically relevant cell numbers, and this might increase the chance of genomic instability. DNA repair is crucial

Nucleic acids research, 35(10), 3355-3366 (2007-05-01)
Evidence has emerged that repair of clustered DNA lesions may be compromised, possibly leading to the formation of double-strand breaks (DSB) and, thus, to deleterious events. The first repair event occurring at a multiply damaged site (MDS) is of major

Oxidative damage to DNA may play an important role in aging and neurodegenerative diseases such as Alzheimer's disease (AD). Attack on DNA by reactive oxygen species, particularly hydroxyl radicals, can lead to strand breaks, DNA-DNA and DNA-protein cross-linking, sister chromatid
