Figure 8. Determination of caspase activation.

Figure 8

Caspase 8 and caspase 6 activity ratios of compound- and actinomycin D-treated cells compared to vehicle-treated cells. Caspase 6 and caspase 8 activities in all compound-treated cells increased when compared to vehicle-treated cells. EMBS-treated cells demonstrated the most prominent increase in caspase 8 activity and ESE-16-treated cells the most prominent increase in caspase 6 activity when compared to vehicle-treated cells. 2-Methoxyestradiol-bis-sulphamate-treated cells are illustrated in the figure as 2MEBM due to limited space. An asterisk (*) indicates a statistically significant P-value of <0.05 when compared to vehicle-treated cells.
