Figure 3. Impact of MnTBAP on mitochondrial function and myocardial substrate metabolism in 13 week-old UCP-DTA mice.

Figure 3

A. Oxygen consumption, ATP synthesis, and ATP/O ratios measured using saponin-permeabilized LV fibers with palmitoyl-carnitine and malate as substrates (n =9–13). B. Oxygen consumption, ATP synthesis, and ATP/O ratios using saponin-permeabilized fibers with glutamate and malate as substrates ( n=6–7). *p<0.05 vs. all or indicated groups. C. Electron microscopy (1:10,000) of left ventricular section in 13 week-old UCP-DTA mice, and quantification of mitochondrial volume density and number. n=4. D–F. Palmitate oxidation, cardiac power and mVO2 measured ex vivo in isolated working hearts (n=6). *p<0.05 vs. all other or indicated groups.
