WebJan 7, 2024 · The increase in ROS will depend on the characteristics of the exercise, such as intensity, time, and frequency [18]. However, it seems that DNA repair likely occurs within a least 3 days [17]. Importantly, regular exercise has been shown to up-regulate the antioxidant defense system and enhance DNA repair processes [19]. WebIn mam- malian cells, DSBs are largely repaired by either homologous recombination repair mechanism (HRR) or non-homologous end joining (NHEJ) repair mechanism [15]. The main difference in HRR and NHEJ is the obligation of a homologous DNA sequence in HRR, which is, therefore, an error-free mechanism.
