A kinetic study of the in vivo incorporation of 65ZN into the rat hippocampus.
Previous autoradiographical studies utilizing 65Zn demonstrated an apparent concentration of 65Zn in the mossy fiber boutons of the hippocampus. To examine the speciation of the 65Zn pool found in this neuronal pathway, we investigated the in vivo incorporation of systemic 65Zn into rat hippocampus compared with other brain regions. We were especially interested in kinetically assessing the zin...
متن کاملThe metabolism of isolated rat-liver nuclei.
The investigations described in this paper were undertaken as a preliminary to the study of the biochemical changes in the nucleus of the rat-liver cell during the induction of liver cancer. Allfrey (1954) and Stern & Mirsky (1953) described the isolation in aqueous media of nuclei from the thymus gland of the calf. Such preparations in vitro incorporated glycine and other amino acids into nucl...
متن کاملActivation of 2-acetylaminofluorene in the nuclei of rat liver.
2-Acetylaminofluonana, a potent hapatocarcinogan, bound to DNA when incubated with an isolated nuclei from mat liven. Nuclear monooxygenase was essential for this binding as shown by dependence on reduced nicotinamide adenina dinucleotide phosphate. The binding was in creased by pretreatment of rats with 3-methylcholanthrane and was completely inhibited by the preincubation of nuclei with the a...
متن کاملSubpopulations of proteasomes in rat liver nuclei, microsomes and cytosol.
Mammalian proteasomes are composed of 14-17 different types of subunits, some of which, including major-histocompatibility-complex-encoded subunits LMP2 and LMP7, are non-essential and present in variable amounts. We have investigated the distribution of total proteasomes and some individual subunits in rat liver by quantitative immunoblot analysis of purified subcellular fractions (nuclei, mit...
متن کاملPresence of multiple protein kinase activities in rat liver nuclei.
The phosphorylation of nuclear proteins has been suggested to play a role in the control of gene readout in mammalian tissues (1,2,3). Phosphorylation of histones has been shown to occur in rat liver in response to hormonal agents (4), and a histone phosphokinase has been isolated from calf liver (5). I.n addition, many of the non-histone (acidic) proteins of the nucleus are phosphoproteins. Th...
