Fig. 9.
One-way ANOVA analysis of IC50 values obtained from 3D-cultured Hep3B cells pre-incubated for 24 h and 72 h, exposed to menadione for 48 h, and stained with TMRM and mBCl for mitochondrial impairment and glutathione level (n= 3, ** p<0.01). Statistically significant difference in IC50 values of menadione was observed at the two pre-incubation conditions, indicating that increase in spheroid sizes reduce mitochondrial impairment and glutathione level-induced toxicity of menadione.
