Re-feeding after starvation involves a temporal shift in the control site of glycogen synthesis in rat muscle.
The starved-to-fed transition is accompanied by rapid glycogen deposition in skeletal muscles. On the basis of recent findings [Bräu, Ferreira, Nikolovski, Raja, Palmer and Fournier (1997) Biochem. J. 322, 303-308] that during recovery from exercise there is a shift from a glucose 6-phosphate/phosphorylation-based control of glycogen synthesis to a phosphorylation-based control alone, this pape...
متن کاملGlucose disposal by skeletal muscle in response to re-feeding after progressive starvation.
We investigated the extent to which increases in glucose utilization indices (GUIs) in individual skeletal muscles during chow re-feeding after 6 h, 24 h or 48 h starvation are related to the antecedent duration of starvation. Chow re-feeding after either acute or prolonged starvation led to an increase in glucose disposal by the muscle mass. Glucose intolerance after prolonged starvation was n...
متن کاملEffects of starvation and re-feeding on growth performance and blood plasma of rainbow trout (Oncorhynchus mykiss)
The mechanism of compensatory growth in rainbow trout (Oncorhynchus mykiss) was studied in a completely randomized design with four experimental treatments and a control group (no food deprivation) with three replicates. Animals in treatments 1 to 4 were fed with rates of 0, 25, 50 and 75% saturation, respectively for two weeks. Then, the treatments were fed twice a day until saturation level f...
متن کاملInhomogeneity of liver glycogen synthesis upon refeeding after starvation.
Normal hepatic glycogen levels are in the range 300-400 pmol/g of tissue wet weight [ 11. Starvation for periods longer than 12 h severely depletes the hepatic glycogen store, as it is rapidly mobilized to provide glucose for extrahepatic tissue metabolism [ 11. Typical levels remaining after mild starvation of 24-48 h are reported as being less than 40 pmol/g of tissue wet weight for the rat a...
متن کاملPyruvate dehydrogenase activities during the fed-to-starved transition and on re-feeding after acute or prolonged starvation.
We investigated the temporal relationship between hepatic glycogen depletion and cardiac and hepatic PDH (pyruvate dehydrogenase complex) activities during the acute phase of starvation. There was a striking correlation between the decline in hepatic glycogen and PDH inactivation during the first 10 h of starvation. Re-feeding after 6 h starvation was associated with complete re-activation of P...
