Plasma triglyceride (Panel A), pancreas ATF-3 (Panel B), and PPARβ/δ (Panel C) expression in 24-hour fasted and 6-hour refed, 40-week-old LF-fed AOiGHD mice. Values are means ± SEM of 6–9 mice/genotype per group. Asterisks indicate significant differences between AOiGHD and controls within group. *, P < .05; ***, P < .001. a, significant differences between refed and fasted expression within genotype. C, Control.
