| Research Abstract |
To evaluate the functional role of FGF21 in the circadian regulation of physiology and behaviour, we examined the temporal expression profiles of Fgf21 and circadian clock genes in addition to behavioural activity rhythms under ad libitum feeding and time-imposed restricted feeding in mice. The free-running period of locomotor activity rhythm under ALF and the food anticipatory activity under RF remained intact in Fgf21 knockout(KO) mice. Temporal expression profiles of circadian clock genes were essentially identical in peripheral tissues between WT and Fgf21 KO mice. Re-feeding subsequent to transient fasting revealed that re-feeding but not fasting remarkably induces Fgf21 expression in epididymal white adipose tissue.
