Objective To observe the differences of the reactive oxygen species (ROS) and mitochondrial membrane potential (ΔΨm) in mitochondrial DNA-depleted SK-Hep1 and its parent cells. Methods ρ
0
SK-Hep1 cell line was generated by treating SK-Hep1 with ethidium bromide. Flow cytometry (FCM) and laser scanning confocal microscopy were used to detect ROS and ΔΨm. Results Fluorescence intensity of ROS in ρ
0
SK-Hep1 cells was significantly higher than that of the parent cells (35.5 vs 15.6)
and the ΔΨm was lower in ρ
0
SK-Hep1 cells (55.0 vs 65.9). Conclusion ρ
0
SK-Hep1 cells sho
wed elevated ROS and lower ΔΨm. These changes might contribute to the variation of phenotypes.
