Variation of deoxyribonucleic acid polymerase activities during rat liver regeneration.
The existence of multiple molecular weight forms of DNA polymerase in different cellular locations of eukaryotie cells, and the demonstration that these enzyme activities have quite different properties (l-4) raise a number of questions about DNA metabolism in complex organisms. Some of these questions were implicit in the early work on mammalian DNA polymerase; particularly the demonstration t...
متن کاملNucleic acid changes during liver regeneration.
Nucleic acid studies on growing normal and pathological tissues have gained ever increasing momentum in recent years. Several investigators (l-7) have presented evidence indicating a high nucleic acid content for neoplastic tissues. It has recently been shown in this laboratory (8-13) that there is an increase in the nucleic acid content of the liver, kidney, and lung of mice bearing a transpla...
متن کاملThe sulphydryl groups of sickle-cell haemoglobin.
particularpH owing to the screening ofthe haematin iron atom from the influence of the various ionizing groups. On this basis a larger critical I would signify that a larger concentration of salt ions is required for complete screening, and hence that there is a stronger interaction between the iron and the ionizing groups in MetHb. In conclusion, although the mechanism may be different it may ...
متن کاملThe interaction of 'soluble' ribonucleic acid, magnesium ions and sulphydryl groups in the control of amino acid-dependent pyrophosphate-exchange reactions.
During an attempt to purify a leucine-activating enzyme from pig-liver-protein fractions low in 'soluble' ribonucleic acid (Hele & Finch, 1960), some fractions became very unstable and lost over half their activity when kept overnight at 15°. In some instances, enzyme activity has been found to be preserved by the presence of 'soluble' ribonucleic acid. In this paper the effect has been further...
متن کاملDecreases during Rat Liver Regeneration
A B S T R A C T The potential role ofepidermal growth factor (EGF) in the regulation of rat liver regeneration was examined by assessing the binding of 1251-EGF to hepatic membranes isolated at various times after partial hepatectomy. The results demonstrated a fall in 125I-EGF binding detectable as early as 8 h after partial hepatectomy. The nadir in EGF binding, <40% of that observed in sham-...
