Restricted feeding entrains liver clock without participation of the suprachiasmatic nucleus

There are two main stimuli that entrain the circadian rhythm, the light‐dark cycle (LD) and restricted feeding (RF). Light‐induced entrainment requires induction of the Per1 and Per2 genes in the suprachiasmatic nucleus (SCN), the locus of a main oscillator. In this experiment, we determined whether RF resets the expression of circadian clock genes in the mouse liver with or without participation of the SCN.
