Hormonal regulation of glycogen metabolism in neonatal rat liver.
1. The development of active and inactive phosphorylase was determined in rat liver during the perinatal period. No inactive form could be found in tissues from animals less than 19 days gestation or older than the fifth postnatal day. 2. The regulation of phosphorylase in organ cultures of foetal rat liver was examined. None of the agents examined [glucagon, insulin or dibutyryl cyclic AMP (6-...
متن کاملGlycogen metabolism in the liver of the neonatal gsd/gsd and control (GSD/GSD) rat.
1. The metabolism of hepatic glycogen, labelled with [6-3H]glucose at day 19.5 of gestation and with 14C from [U-14C]galactose at delivery, was followed for 10 h in food-deprived gsd/gsd and control (GSD/GSD) neonatal rats. 2. In the affected pups glycogen was maintained at 12% (w/w) and there was no loss of incorporated radioactivity. 3. The 3H and 14C in glycogen from the controls were both d...
متن کاملInfluence of thyroid hormone on glycogen metabolism in rat liver.
The livers removed from thyroidectomized and L-T4 supplemented rats were rapidly frozen by Freon-12 chilled with liquid nitrogen, and concentrations of metabolites which affect glycogen synthetase and phosphorylase were determined. Serum and liver glycose levels were not changed in any thyroid functioning. But liver G6P and ATP were increased by thyroidectomy and decreased by L-T4 supplement, w...
متن کاملEffect of Serotonin on Glycogen Metabolism in Isolated Rat Liver.
In the invertebrate liver fluke, Fasciola hepatica, there is evidence that 5-hydroxytryptamine (serotonin) increases glycolysis (1, 2), glycogenolysis (1), and phosphorylase activity (3). However, previous studies in mammalian liver, in vitro and in vivo, have yielded conflicting results concerning the effect of serotonin on hepatic glycogen content, hepatic phosphorylase, and blood glucose. So...
متن کاملDietary and hormonal regulation of enzymes of fructose metabolism in rat liver.
Fructokinase (ketohexokinase, EC 2.7.1.3), aldolase (ketose-1-aldehyde lyase, EC 4.1.2.7), and triokinase (ATP: D-glyceraldehyde 3-phosphotransferase, EC 2.7.1.28) activities of rat liver were measured under various dietary and hormonal conditions. Specific activities in terms of liver weight did not change greatly, but marked changes were observed in total liver activity. All three activities ...
