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

Figure 5

The effect of CNPs on CAT activity in YM1 and CSC-LC cell lines. CAT activity increased significantly in both YM1 and CSC-LC cell lines in comparison to the control (untreated cells). Section (a): CAT activity in YM1 cell line. Section (b): CAT 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, CAT: catalase).
