To clarify whether apoptosis by C2 fraction of LTE is linked to mitochondria dysfunction, we examined the effect of C2 fraction on the ΔΨ m with a mitochondria-specific dye, DiOC6(3). As shown in Fig. 5(A), a time-dependent loss of ΔΨ m was observed after treatment with 50 μg/mL for 6, 12, and 24 h. The loss of ΔΨ m commonly leads to the release of cytochrome c from mitochondrial membrane to cytosol, which causes activations of caspases to induce apoptosis. Thus, we further analyze whether mitochondrial cytochrome c releases into cytosol.
