The mTOR/GCLc/GSH Pathway Mediates the Dose-Dependent Bidirectional Regulation of ROS Induced by TiO2 NPs in Neurogenic Cells
Figure 5
Intracellular H2O2 levels (a), SOD activities (b), CAT activities (c), and GSH-Px activities (d) were determined after U251 cells, and SK-N-SH cells were exposed to 1 μg/ml and 100 μg/ml of TiO2 NPs, respectively. All data are presented as , and each assay was repeated three times. Blank means blank control, , , .
