Figure 5. The pan-caspase inhibitor alleviates iopromide-induced cell death. HEK 293 cells were incubated with 50 mgI/ml iopromide in the absence or presence of the pan-caspase inhibitor (Z-VAD-FMK) for 48 h. Cell viability was evaluated using the MTT assay. The results are expressed relative to those of the untreated control and values are presented as mean±SE (n=3) (***p<0.001).
