a-I, Echocardiography measurements taken at 16 weeks of age after 10 weeks of low fat (LF), medium chain triglyceride (MCT), or high-fat (HF) feeding. Left ventricular internal diameter at end diastole (LVIDd) and end systole (LVIDs), fractional shortening (FS), relative wall thickness (RWT), end diastolic volume (EDV), end systolic volume (ESV), stroke volume (SV), and cardiac output (CO) (n=5, 4, 4, 8, 4, and 5, respectively). j-l, Cardiac gene expression for Ppara and it’s targets Acot1 and Hmgcs2 (n=11, 6, 10, 8, 4, and 5, respectively). Data are presented as mean ± s.e.m. within dot plot. Each data point represents an individual mouse. Two-way ANOVA with Tukey’s multiple comparisons test.
