A, Messenger RNA expression of CPT-1b a key gene involved in fatty acid oxidation. Data (mean ± standard error of the mean) are expressed as the ratio of CPT-1b: reference gene (L19), N = 11. B, Representative Western blot of CPT-1b in a placenta. C, Densitometry analysis of CPT-1b protein expression, N = 8. *P < .05 vs 0 µM by Friedman repeated-measures analysis of variance and Dunn multiple comparison testing. AU indicates arbitrary units.
