Membrane potential (ΔΨ) of mitochondria from cultured normal human prostate PrEC cells, prostate cancer cells PC-3, DU145, LNCaP, human fibrosarcoma cells HT1080C, and HLB oxidizing succinate in the metabolic State 4.

<p>Incubation conditions and calculation of ΔΨ as -mV are described in Methods. Values are expressed as Mean (-mV) ± SE. Statistics: ** <i>p</i> < 0.05; *** <i>p</i> < 0.001. Values for prostate cancer cells PC-3, DU145 and LNCaP were compared with normal prostate cells PrEC.
