Additional file 4: of N-acetylcysteine decreases malignant characteristics of glioblastoma cells by inhibiting Notch2 signaling

Figure S4. NAC and BSO decreased levels of total cellular GSH in GBM cells. A, Total cellular GSH was measured in U87 and U251 cells under pre-treatment of BSO (1 mM, 12 h), followed by NAC (10 mM, 24 h). B, Total cellular GSH was measured in U87 and U251 cells under pre-treatment of BSO (2 mM, 12 h), followed by NAC (20 mM, 24 h). All data are presented as means ± SD of three independent experiments. * P < 0.05 compared with EV group, # P < 0.05 compared with EV + NAC + BSO group. (TIF 5696 kb
