Advances in Enzyme Regulation, 1964
Summary Following stimulation with adrenal steroids a series of metabolic changes occur leading to increased protein catabolism and increased glucose production. Specific hepatic enzymes whose activities are known to increase under these conditions are: glucose-6-phosphatase, phosphohexose isomerase, fructose diphosphatase, phosphoenolpyruvate ...

Journal of Inherited Metabolic Disease, 1996
SummaryGluconeogenesis, or the formation of glucose from mainly lactate/pyruvate, glycerol and alanine, plays an essential role in the maintenance of normoglycaemia during fasting. Inborn deficiencies are known of each of the four enzymes of the glycolytic — gluconeogenic pathway that ensure a unidirectional flux from pyruvate to glucose: pyruvate ...

Hepatic gluconeogenesis in chickens
Molecular and Cellular Biochemistry, 1978Gluconeogenesis by isolated hepatocytes resulted in glucose release but insignificant rates of glycogen synthesis. The effectiveness of precursors was similar for hepatocytes from fed and starved chickens except for impaired gluconeogenesis from pyruvate when compared to lactate in lactate starved chicken hepatocytes.

Quantifying gluconeogenesis during fasting
American Journal of Physiology-Endocrinology and Metabolism, 1997The use of2H2O in estimating gluconeogenesis’ contribution to glucose production (%GNG) was examined during progressive fasting in three groups of healthy subjects. One group ( n = 3) ingested2H2O to a body water enrichment of ≈0.35% 5 h into the fast. %GNG was determined at 2-h intervals from the ratio of the enrichments of the hydrogens at C-5 and C-

It is a characteristic of all avian species that they maintain a plasma glucose concentration between 9 and 15 mM under all physiological circumstances. Even starvation for up to 9 days failed to lower the blood sugar concentration of chickens (Hazelwood & Lorenz, 1959).

Gluconeogenesis following Hypothalamic Stimulation
Nature, 1966IN previous experiments1,2, a rise in serum glucose, and increased endogenous gluconeogenesis in liver slices, was found 5 min after the injection of 50–100 mg of 2-deoxy-glucose (2 DG), an inhibitor of glucose utilization, into fasting rats. 2 h after administration of 2 DG, an accumulation of liver glycogen was observed.

Gluconeogenesis in vertebrate livers
Comparative Biochemistry and Physiology Part B: Comparative Biochemistry, 19771. The hypothesis is advanced that it would be logical for a tissue (liver) to evolve as a gluconeogenic organ in order to recover the lactate produced as a result of rapid and sustained contraction of skeletal muscle. 2. Lactate was present in skeletal muscle of all animals examined and increased following electrical stimulation.

Gluconeogenesis, the de novo formation of glucose from non-carbohydrate precursors, is confined to the proximal convoluted and proximal straight tubules of the mammalian kidney. Compared to liver, renal gluconeogenesis has different substrate requirements and responds to different regulatory stimuli.

Gluconeogenesis and Redox State
1971Summary It has been known for some time that the redox state of the NAD-couple in the liver, as measured by the [lactate]/[pyruvate] ratio, moves in the direction of reduction when the rate of gluconeogenesis increases. It was not evident however whether the redox state is of regulatory importance; in other words, whether the change in the redox ...
