Figure 8.

Protein fractional synthesis rates (FSRs) by GC‐MS and amino acid concentration by 1H‐NMR from left ventricular tissues. A, 13C‐MPE of intracellular free leucine. B, FSRs. RELOAD significantly increased 13C‐MPE of leucine, and cardiac FSRs by >75% over UNLOAD. C, Amino acid concentration. Glutamate concentration was decreased, while glutamine was increased in RELOAD. Clear column: UNLOAD; black column: RELOAD. Values are means±SE; n=6 to 8 per group. *P<0.05, P<0.01 compared with UNLOAD. GC‐MS indicates gas chromatography/mass spectroscopy; NMR, nuclear magnetic resonance; MPE, 13C‐molar percent enrichment; SE, standard error.
