Toxic Prediction of Pyrrolizidine Alkaloids and Structure-Dependent Induction of Apoptosis in HepaRG Cells

Figure 6

Effect of 4 PAs on the apoptosis of HepaRG cells (a, b). Distribution of apoptosis in HepaRG cells after treated with different concentrations (0, 50, and 200 μM) of 4 PAs for 24 h. 10 μM CPT was used as a positive control. indicates a significant difference versus the control group.
