Mitochondrial genes that were significantly different between HFCs and HKCs, either in controls, T1, or T3. A) SOD2 was significantly up-regulated in HCFs when compared to HKCs, independent of treatment; B) PMAIP1 was significantly down-regulated in control HKCs, compared to HCFs; C) BNIP3 was significantly down-regulated in HKCs when compared with HCFs under T1 and T3 treatments. All samples were repeated at least three times, with p<0.05 considered to be statistically significant ($$$p<0.0001, $$p<0.001, $p<0.01, ***p<0.0005, **p<0.005, *p<0.05).
