Cerium Oxide Nanoparticles Induced Toxicity in Human Lung Cells: Role of ROS Mediated DNA Damage and Apoptosis

Figure 8

Cell cycle analysis of A549 cells exposed to CeO₂ NPs for 24 h exposure. Cells were exposed, fixed, and stained with propidium iodide dye before subjecting to flow cytometric analysis. Values from three independent experiments (mean ± SEM) were reported where ^∗𝑃<0.05 and ^∗∗𝑃<0.01 compared to control.
