Figure 1

Serum corticosterone and PER1 protein levels are entrained by food access. Diurnal corticosterone levels in rats fed ad libitum (AL) and under RF are shown in panel A. Quantitative analysis of clock protein PER1 using 50 μg of cytosolic fraction from at least 4 individuals is represented in panel B. Each value was normalized using the housekeeping protein actin as reference, and a representative western blot for each condition is shown. Black circles correspond to AL and white circles to RF group. The light gray rectangle above the x-axis represents mealtime for the food restricted group (ZT4-ZT6); * (p < 0.05) means significant difference among AL group time points and + (p < 0.05) significant difference among RF group time points (1-way ANOVA). # (p < 0.05) significant difference between AL vs RF (2-way ANOVA).
