Figure 6From: Phenylhexyl isothiocyanate has dual function as histone deacetylase inhibitor and hypomethylating agent and can inhibit myeloma cell growth by targeting critical pathwaysPHI causes disruption of mitochondrial membrane potential in RPMI8226 myeloma cells. The myeloma cells were treated with 5 μM and 10 μM of PHI, respectively for 48 hours. The cells were then stained with JC-1 dye. The mitochondrial membrane potential was measured by flowcytometry as described in the Material and Methods. The shift-down of fluorescence from Red to Green indicates the collapse of mitochondrial membrane potential. CCCP was used as a positive control for the disruption of mitochondrial membrane potential. The percent of cells with the disruption of mitochondrial membrane potential was indicated.Back to article page
