Effects of proteasome inhibition on mitochondrial membrane potential. Cells were incubated in the absence or presence of 10 μmol/L methylprednisolone with or without 25 μmol/L zAPFcmk or 10 μmol/L MG132. Mitochondrial membrane potential was assessed by the potential sensitive fluorochrome JC-1 and quantitated by FACS analysis.
