MitoPeroxidase 2 impedes the activity of caspase 3 in MEC. Cells were exposed to IR (10 Gy) and then treated with 20 μM MitoPeroxidase 2 as indicated in Figure 2. Caspase 3 activity was determined by EnzChek Caspase 3 Assay Kit (Z-DEVD-AMC substrate; Life Technologies, Grand Island, NY). The results represent the mean + SD (n = 3).
