Caki-1 cells were treated with mdivi-1 alone, cisplain alone or combined treatments. To measure DNA fragmentation, we used cell death detection ELISA plus kit (Boehringer Mannheim, Indianapolis, IN, USA) according to the manufacturer’s recommendations. For caspase activity assay, cells were harvested and incubated with a reaction buffer containing acetyl-Asp-Glu-Val-Asp p-nitroanilide (Ac-DEVD-pNA), acetyl-Ile-Glu-Thr-Asp-p-nitroanilide (Ac-IETD-pNA), or Ac-Leu-Glu-His-Asp-p-nitroaniline (Ac-LEHD-pNA) substrate, as previously described [29 (link)].
