Fig. 3. Gene expression and cardiac metabolism. Principal components (PC) summarize
metabolic pathway gene expression. The nine graphs illustrate which metabolic
pathway explains the most variation in substrate-specific metabolism for the
three groups. FA, fatty acid; LKA, lactate, ketones and alcohol; Gly,
glycolysis; OxP, oxidative phosphorylation; TCA, tricarboxylic acid. Modified
from Oleksiak et al. (Oleksiak et al.,
2005).
