Effects of caspase inhibitor on cell viability in TcCaNB-stimulated tumor and nontumor cells. HeLa and Vero cells were treated with different concentrations of TcCaNB in the presence of Z-VAD-FMK ([20 μM]_f) for 24 h. Cell viability was determined by the MTS assay. Results were expressed as average of triplicates ± SD (n = 4, two-way ANOVA and Sidak's test, ⁣^∗p < 0.05; ⁣^∗∗∗p < 0.001; ⁣^∗∗∗∗p < 0.0001; ns: not significant). The asterisks indicate significant differences between the different TcCaNB concentrations in the presence and absence of the Z-VAD-FMK inhibitor.
