Purification of thioredoxin from rat Novikoff ascites hepatoma.
Partial purification of a thioredoxin system from Novikoff ascites hepatoma cells has been previously reported (MOORE, E. C. (1967) Biochem. Biophys. Res. Commun. 29, 264-268). Thioredoxin from the same mammalian source has now been purified to electrophoretic homogeneity by ammonium sulfate fractionation, heat treatment, DEAE-cellulose chromatography, and Sephadex chromatography. 1-Dimethylami...
متن کاملGlycogen metabolism in Novikoff ascites-hepatoma cells.
A study of the enzymes of the glycogen pathway in Novikoff ascites hepatoma shows that glycogen synthetase has the lowest activity and that the tumour contains no high-K(m) soluble glucokinase. However, incubation of tumour cells with metabolizable sugars in vitro, or intraperitoneal administration of glucose into the tumour-bearing rat, results in glycogen accumulation by the tumour cells. Gly...
متن کاملDifferences between pyrimidine nucleoside monophosphate kinase from rat Novikoff ascites hepatoma and rat liver.
Pyrimidine nucleoside monophosphate kinase [deoxycytidine monophosphate:adenosine triphosphate (dCMP:ATP) phosphotransferase. EC 2.7.4.14] has been purified from rat Novikoff ascites hepatoma and rat liver, each to a single major band appearing on sodium dodecyl sulfate polyacrylamide gel electrophoresis. Differences exist in regard to efficiency and regulation of enzymatic activities. The Km v...
متن کاملPasteur Effect in Novikoff Ascites-hepatoma Cells.
Inhibition of fermentation or of glucose uptake in the presence ofoxygen has been observed in many forms of life and is generally referred to as the 'Pasteur effect'. In most tissues, oxidative inhibition of fermentation (ethanol or lactate production) is reflected by a parallel decrease in glucose consumption. Since certain tissues utilize lactate significantly, estimation of the Pasteur effec...
متن کاملPurification of a ribonuclease inhibitor from Novikoff hepatoma supernatant fraction.
A comparison between the levels of ribonuclease inhibitor in normal rat liver and Novikoff hepatoma 105,000 X g supernatant fractions is reported. Novikoff hepatoma con tained 61% less inhibitor per g of tissue or 39% less per mg protein than did normal rat liver. A rapid and simple method that had been developed for the purification of rat liver ribonuclease inhibitor was applied to Novikoff h...
