a Mitochondrial mass, b ROS in Huh7-NTC and shPINK1 subclones exposed to 20 and 1% O2 for 24 h. c Huh7-NTC, -shPINK1-01, shPINK1-93 cells were exposed to 20 and 1% O2 for 24 h. Cell images under transmission electron microscope (TEM). d Proliferation of Huh7-NTC and shPINK1 subclones exposed to 20 and 1% O2 for 4 days. Data are presented as mean ± s.d.
