Cearoin increases the intracellular reactive oxygen species (ROS) production and nitric oxide (NO) generation in neuroblastoma SH-SY5Y cells. SH-SY5Y neuroblastoma cells were treated with cearoin in various concentrations (0, 10, 20, 40, 80, or 160 μM) and incubated for 12 h. (A) Intracellular ROS production was measured using DCFDA fluorescence assay. Each bar represents the mean percentage alterations above the control (±SD) (n = 5); (B) total NO release was measured using Griess method. Each bar represents the mean nitrite concentration (±SD) (n = 6). Differences were considered statistically significant at * p < 0.05 and *** p < 0.001 as compared with the control.
