Addition of millimolar amounts of a weak base (pyridines) dramatically accelerates the reaction with peroxyl radicals of two biologically relevant uracil derivatives, 5-hydroxyuracil (HU) and 5-hydroxy-6-methyluracil (HMU). This is due to the formation of small amounts of the deprotonated form

Oxidative lesions represent the most abundant DNA lesions within the cell. In the present study, we investigated the impact of the oxidative lesions 8-oxoguanine, thymine glycol and 5-hydroxyuracil on RNA polymerase II (RNA pol II) transcription using a well-defined in

5-Hydroxyuracil is a major oxidized nucleobase that can be generated by the action of (*)OH radical and one-electron oxidants. The latter modified base that exhibits a low ionization potential is highly susceptible to further degradation upon exposure to various oxidants.

Base excision repair (BER) is the major pathway for the repair of simple, non-bulky lesions in DNA that is initiated by a damage-specific DNA glycosylase. Several human DNA glycosylases exist that efficiently excise numerous types of lesions, although the close

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
