From: Up-regulation of avian uncoupling protein in cold-acclimated and hyperthyroid ducklings prevents reactive oxygen species production by skeletal muscle mitochondria

Figure 4

Effect of increasing doses of palmitate on non-phosphorylating respiration of skeletal muscle mitochondria from T 3 -treated ducklings in the presence (dark circles) or absence (open circles) of xanthine/xanthine oxidase (XXO). Mitochondria were isolated from T3-treated ducklings and respiration was initiated with 5 mM succinate in the presence of 0.3% FAF-BSA. Values are means ± SEM from 5-6 determinations. * indicates a significant (P < 0.05) interaction between the dose of palmitate and the addition of XXO implying a higher stimulation of XXO at a given palmitate concentration.
