| Outline of Final Research Achievements |
We examined the roles of carnitine in the general metabolism and the central nervous system, and the prolonged effects of carnitine administration to the fasted carnitine-deficient juvenile visceral steatosis (JVS) mice. Fasting reduced locomotor activity (LA) of JVS mice. Single carnitine administration caused an increase of the reduced LA and the fat expenditure, and the effects were prolonged for at least two days after the administration (as low as at the original carnitine-deficient state). In JVS mice, fasting also caused a decreased percentage of c-Fos positive orexin neurons in the lateral hypothalamus (ameliorated by carnitine administration). These results suggest that the reduced LA in fasted JVS mice is related to the inhibition of orexin neuronal activity.
