TP53 and nasopharyngeal carcinoma: The DSF/Cu can exert antitumor activity in nasopharyngeal carcinoma cells through the ferroptosis pathways mediated by ROS/MAPK and p53, while the ROS scavenger N-acetyl-L-cysteine (NAC) has the ability to regulate the concentrations of reactive oxygen species within nasopharyngeal carcinoma cells and the lipid levels.
