Also, the focus formation after chemotherapy could provide us with additional information regarding the DNA damage-response capacity.
This preferential activation of the DNA damage response increases DNA repair capacity that is essential for tumor cell survival.
The DNA damage response limits cellular proliferative capacity (Behrens et al., 2014).
Indeed, previous studies have suggested that there is an association between systemic oxidative stress and diseases, such as an association of the high prostate cancer risk with severe damage response and poor repair capacity of nuclear DNA in lymphocytes [ 14].
To test the physiological implications of c-Abl activity in the context of DSB repair and the DNA damage response, we tested the clonogenic capacity of cells abrogated for c-Abl activity.
At present, one cannot translate a differential capacity for DNA damage response and tumor cell senescence in TICs to a globally resistant tumor cell phenotype.
Major transportation routes, such as Interstate 5 (north-south) and the North Cascades Highway (east-west), intersect the lahar zone and damage to these networks could negatively impact response capacity.
Altogether, Lxn impairs DNA repair capacity and suppresses DNA damage response, leading to accumulation of unrepaired DNA damages in Lxn-overexpressing cells.
Indeed, several studies showed that experiments conducted on mussels at atmospheric pressure lead to a global increase of stress parameters (lipid peroxidation, anti-oxidant enzymes activity, DNA damage) and to a limitation of stress response capacity [ 14, 23, 102].
Short and dysfunctional telomeres limit cellular proliferative capacity by eliciting a DNA damage response.
In senescent cells, a DNA damage response drives not only irreversible loss of replicative capacity but also production and secretion of reactive oxygen species (ROS) and bioactive peptides including pro-inflammatory cytokines.
