...Summer Savon; Parvin Hakimi; Richard W. Hanson Gluconeogenesis in the chicken has unique features due in part to the presence of two isozymes of PEPCK, a cytosolic form, PEPCK-C, and a mitochondrial form, PEPCK-M, which have novel patterns of expression. Here we show that, in contrast to mammals...

...D. Sadava; P. Frykman; E. Harris; D. Majerus; J. Mustard; B. Bernard The activities of two key enzymes of glycolysis and two key enzymes of gluconeogenesis were measured in liver samples from 44 human fetuses ranging in gestational age from 20 weeks to term, from infants to 10 years and from adults...

... be avoided by stimulation of neonatal gluconeogenesis which is limited by glucose infusion and/or insulin secretion. Lipid administration induces a hyperglycemic response which is explained by a stimulation of gluconeogenesis. It also results in ketogenesis which provides the compensatory factors...

...Jean Girard Birth represents a dramatic change of nutrition from a fetal diet rich in carbohydrates and poor in fat to a neonatal diet rich in fat and poor in carbohydrates. Gluconeogenesis and ketogenesis are absent or very low in the fetal liver when the mother is correctly fed...

... by hypoxia, showing a direct correlation with blood oxygen concentrations. Lactate was not converted into glucose during the presuckling period, gluconeogenesis being insignificant in these circumstances; instead it was rapidly oxidized through the tricarboxylic acid cycle. Likewise, lactate...

... glycogenolysis and gluconeogenesis, and hence postnatal hypoglycemia is reversed. In the suckling period, the oxidation of fatty acids, ketone bodies utilization and active gluconeogenesis supply the bulk of the energy and carbon components required to support the rapid growth rate of this period. The increase...

...Jean Girard Birth in most mammalian species represents an abrupt change from a high-carbohydrate and low-fat diet to a high-fat and low-carbohydrate diet. Gluconeogenesis is absent from the liver of the fetus of well fed mothers, but can be induced prematurely by prolonged fasting of the mother...

...J.P. Pégorier; P.H. Duée; J.R. Girard The inhibition of hepatic gluconeogenesis by 3-mercaptopicolinic acid (3-MPA) leads to a profound hypoglycemia in both suckling and fasting 24-hour-old rabbits. This hypoglycemia is totally reversed 1 h after the intragastric injection of an amount of galactose...

... increases by 30% the rate of gluconeogenesis from lactate. In hepatocytes isolated from fasting newborn pigs, addition of glucagon (0.5 ng/ml) produces a 30% increase in the rate of glucose production from lactate and a 70% increase of glucose synthesis from dihydroxyacetone. The high rate of lactate plus...
