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

Figure 9

Dose dependent expression level analysis (A, B, and C) of various apoptotic proteins in A549 cells after 24 h exposure of CeO₂ NPs. Cells exposed to indicated concentration, protein lysate, were collected and assayed by western blotting. β-actin was used as an internal control. All blots (A, B, and C) and respective Bar graph (Aa, Bb, and Cc) values (mean ± SEM) are representative of three independent experiments (^∗𝑃<0.05, ^∗∗𝑃<0.01 compared to respective control).
