Immunoblots for markers of mitochondrial metabolism and biogenesis in skeletal muscle and liver from mice fed the low-fat
(LF), MCFA, and LCFA diets. Equal amounts of muscle lysates (10–20 μg protein) were resolved by SDS-PAGE and immunoblotted
with specific antibodies for PGC-1α, CPT-1, UCP3, and mitochondrial respiratory chain subunits. Densitometric analysis (relative
to low-fat controls) for n = 6 animals is presented. *P < 0.05; †P < 0.01 vs. low fat; ‡P < 0.05; §P < 0.01 vs. MCFAs.
