Propionic acid metabolism in mouse liver slices.
Odd carbon fatty acids are considered to be oxidized in tissue by successive fl oxidation in much the same way that even carbon members of the series are (14). The terminal S-carbon unit has been investigated to some extent. Atchley (5) demonstrated propionic acid as an end-product in the oxidation of valeric acid by a rabbit enzyme system. Studies on malonate inhibition with odd carbon fatty a...
متن کاملControl of Gluconeogenesis in Rat Liver Cells
Control of gluconeogenesis from lactate was studied by titrating rat liver cells with lactate and pyruvate in a ratio of 1 O : l in a perifusion system. At different steady states of glucose formation, the concentration of key gluconeogenic intermediates was measured and plotted against gluconeogenic flux (Jglucoee). Complete saturation was observed only in the plot relating JglUcto the extrace...
متن کاملglycolysis/gluconeogenesis in regenerating rat liver
Levels of mRNA for glucokinase, L-pyruvate kinase, fructose-1,6-bisphosphatase and phosphoenolpyruvate carboxykinase were analysed during liver regeneration. Levels of mRNA for glycolytic enzymes (glucokinase and L-pyruvate kinase) decreased rapidly after partial hepatectomy. Glucokinase mRNA increased at 16-24 h, returning to normal values after this time. L-pyruvate kinase mRNA recovered cont...
متن کاملGluconeogenesis in Neonatal Piglet Liver 1
The gluconeogenic capacity of livers from day old and 5-day-old piglets has been studied. The data show infused piglets and perfused livers convert lactate to glucose. Studies with isolated liver mitochondria show a large capacity to flux pyruvate through the pyruvate carboxylase reaction causing an accumulation of malate, citrate and phosphoenolypyruvate. Factors that affect accumulation of ma...
متن کاملIDH1 deficiency attenuates gluconeogenesis in mouse liver by impairing amino acid utilization.
Although the enzymatic activity of isocitrate dehydrogenase 1 (IDH1) was defined decades ago, its functions in vivo are not yet fully understood. Cytosolic IDH1 converts isocitrate to α-ketoglutarate (α-KG), a key metabolite regulating nitrogen homeostasis in catabolic pathways. It was thought that IDH1 might enhance lipid biosynthesis in liver or adipose tissue by generating NADPH, but we show...
