The Anticancer Role of Cerium Oxide Nanoparticles by Inducing Antioxidant Activity in Esophageal Cancer and Cancer Stem-Like ESCC Spheres

Figure 6

The effect of CNPs on SOD activity in YM1 and CSC-LC cell lines. SOD activity increased significantly after treatment with CNPs in both cell lines in comparison to the control (untreated cells). Section (a): SOD activity in YM1 cell line. Section (b): SOD activity in CSC-LC. ( shows a significant difference between each concentration and the control group and ^# shows a significant difference between different concentrations) ( or ^# value < 0.05, or ^## value < 0.01, or ^### value < 0.001, or ^#### value < 0.0001) (CNP: cerium oxide nanoparticle, SOD: superoxide dismutase).
