Transmission electron microscopy (TEM) and respiration in liver samples from male C57/BL6 mice fed 0.4% (w/w) TTP, 0.4% (w/w) TTA, or TTP + TTA for 3 weeks. a Representative images from TEM, 10,000 x magnification and, (b) estimation of number of mitochondria from 3 to 4 TEM images per animal (n = 4). c Oxygen consumption at the different stages in the SUIT protocol (n = 4-6). d Oxygen consumption divided by the average number of mitochondria in the different treatment groups (n = 4–6). e Hepatic gene expression of Ndufs, (f) Sdha, and (g) Ucp2 (n = 8). Values are means with standard deviations. Significant difference from controls was determined using one-way ANOVA with Dunnett’s post hoc test (*p ≤ 0.05, **p ≤ 0.01, ***p ≤ 0.001)
