Mitochondrial DNA and Functional Investigations into the Radiosensitivity of Four Mouse Strains

Table 1

RCI and ROS measured in isolated hepatic mitochondria from C57BL/6 and BALB/c mice and their F1 hybrids.

Mouse strain	RCI	ROS (pMol/min/mg)
C57BL/6	3.62 ± 0.47	14.14 ± 1.36
BALB/c	3.60 ± 0.39	16.45 ± 1.95
C57BL/6 F × BALB/c M	2.87 ± 0.33	16.28 ± 2.89
BALB/c F × C57BL/6 M	3.69 ± 0.43	18.96 ± 2.09

Abbreviations: RCI: respiratory control index; ROS: reactive oxygen species.
