Mitochondrial genes that were significantly regulated by T1 and/or T3, in HCFs, when compared to controls: A) PMAIP1 was significantly down-regulated with T1 and T3; B) BNIP3 was significantly up-regulated with T1 and T3; C) CPT1B was significantly higher with T1 when compared to control and T3. T3 was significantly higher compared to control; D) NEFL was significantly higher with T1 compared to controls 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).
