Effect of the treatment with Aβ peptide on oxidative damage in SH-SY5Y cells. Cells were treated with the Aβ peptide for the times and the conditions indicated. ROS (panel a) and malondialdehyde (panel b) levels were determined as reported in the Material and Methods section. In panel a, hydrogen peroxide was used as positive control. Three independent experiments were carried out, and the values were expressed as mean ± sd. * denotes p < 0.05 vs. the control; ** denotes p < 0.01 vs. the control; *** denotes p < 0.001 vs. the control. Student’s two-tailed t test was performed.
