Many anti-tumor drugs can induce tumor apoptosis by increasing intracellular ROS. In the present study, we build a model which did not directly cause DNA damage, but simulated damage products. The model of this injury was transferred into the cell so that the cell’s damage recognition mechanism mistakenly recognized that its own DNA was damaged, which in turn induced a response. Based on this model, the damaged plasmids (exogenous DNA damage) were transferred into the cells and the amount of reactive oxygen in the cells was improved, and DNA damage of the cells was increased. Therefore, exogenous DNA damage can affect the accumulation of damage in cells by affecting the level of reactive oxygen species, which provides a reference for DNA damage repair research.
