...A. Ichihara There are three forms of branched-chain amino acid transaminase (EC 2.6.1.6), i.e. enzymes I–III, in various rat tissues. Enzyme I is distributed ubiquitously in all tissues examined,while enzymes II and III are found only in liver and brain,respectively. During development, fetal liver...

...E. Bailey; Elizabeth A. Lockwood Changes in hepatic and heart fatty acid oxidation, hepatic ketogenesis and utilization of ketone bodies by extrahepatic tissues during development of the rat are described. Factors involved in the developmental changes in these aspects of lipid metabolism of the rat...

...R.W. Hanson; Linda Fisher; F.J. Ballard; Lea Reshef The activity of phosphoenolpyruvate carboxykinase in the liver of fetal rats can be induced in utero by administration of either glucagon or dibutyryl-cAMP to the fetuses. Both of these compounds cause a rapid rise in enzyme activity,followed...

...J.K. Pollak; C.G. Duck-Chong A large number of investigations into changes in rat liver mitochondria and endoplasmic reticulum during development and differentiation have been reviewed in the light of current ideas about the dynamic nature of membranes. Particular attention has been paid...

...R.L. Jacquot; C. Plas; J. Nagel Two physiological maturations of the rat liver are presented in this paper. The ability for glycogen storage depends in vivo on the presence of endogenous circulating glucocorticoids. Similarly, in vitro, primary cultures of fetal hepatocytes store glycogen only...

...Salvatore Sech; David Parmelee; Peter P. Roller; Gary T. Jennings Cytosolic NADP+-dependent isocitrate dehydrogenase was purified to homogeneity from superovulated rat ovaries. Amino acid sequence information was obtained by analyzing peptides generated by digestion with either cyanogen bromide...

..., 2, 3, and 4 h, respectively. Once again, psoralen irradiated for 6 h did not bring further increased inhibition. Feeding of psoralen to albino rats for one week was not found to bring about any change in the glucose oxidation of brain, whereas the oxidation in liver was inhibited to the extent of 23...

...Raymund Machovich The concentration of rat pancreatic nonspecific esterase increases steadily after birth. The ingestion of oil enhances this rise. 11 8 2017 Short Communications Enzyme 17: 265-268 (1974) Postnatal Development of Rat Pancreatic Esterase1 Raymund Machovich The Cancer...

...Olga Greengard; N. Lempert In rats carrying Walker carcinomas transplanted subcutaneously,splenomegaly (a 2- to 5-fold increase in spleen weight) is associated with striking increases (5- to 30-fold/g spleen) in the concentration of thymidine kinase. This may reflect active erythropoiesis since...

...T. Satoh Intraperitoneal administration of isocarboxazid, hydrazine type MAO-inhibitor, caused an increase in liver tryptophan pyrrolase activity of rat. This fact was attributed to an elevation of plasma free tryptophan released by isocarboxazid and its active metabolite, benzylhydrazine. 11...

...G. Budillon; C. del Yecchio-Blanco; M. Coltorti Some enzymatic activities of the major degradation pathways for histidine (histidine ammonialyase[EC 4.3.I.3.], urocanase, and histidine pyruvate aminotransferase) have been studied in the livers of mice, rats, and men. The reduction in the enzymatic...

...M. McGee; O. Greengard; W.E. Knox An assay is described for the quantitative measurement of asparaginase in crude preparations of rat tissues. Most of the asparaginase is concentrated in the liver, in the cytosol, with a Km of 4.71 X 10^-3M for asparagine. The activity is twice as high in adult...

...) are described. As little as 0.5 mg (0.25 mg/ml) of brain tissue or 0.5 pg of bovine trypsin are required. The ‘neutral proteinase’ of rat brain studied had a pH optimum at 7.3—7.4 and was inhibited by calcium. Trypsin inhibition by brain homogenates had peaks at pH 7.8 and 8.4. Brain Fluorometry (micro-) N...

...Annemarie Herzfeld With an improved method of solubilization and assay, glutamate dehydrogenase (EC 1.4.1.2) was quantified in a series of normal and neoplastic rat tissues. Fetal and neoplastic tissues had generally low activities but in mammary tumors and rhabdomyosarcoma the activity exceeded...
