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

Figure 6

Release of H 2 O 2 by intermyofibrillar mitochondria isolated from red gastrocnemius muscle of thermoneutral controls (TN), cold-acclimated (CA), hypothyroid (hypo) or T 3 -treated (T 3 ) ducklings. Oxygen consumption (JO2) was measured in parallel, and H2O2 production was expressed per oxygen consumed. Measurements were performed in the presence of 0.3% FAF-BSA and 5 mM succinate without (black columns) or with 1.5 mM GDP (open columns) or with 1.5 mM GDP + 5 μM rotenone (grey columns). Within an experimental condition of respiration (succinate, succinate + GDP or succinate + GDP + rotenone), bars with different letters are significantly different (P < 0.05). * indicates a significant effect of GDP (P < 0.05); § indicates a significant effect of rotenone (P < 0.05).
