INHIBITION OF RIBONUCLEOSIDE METABOLISM IN EHRLICH ASCITES TUMOR CELLS BY PURINE ANALOGUE RIBONUCLEOSIDES

Canadian Journal of Biochemistry, 1965
Several aspects of the metabolism of inosine and uridine by Ehrlich ascites carcinoma cells in vitro have been found to be inhibited by ribonucleoside derivatives of four purine analogues. The synthesis of both inosine and uridine by intact tumor cells was profoundly inhibited in the presence of 6-methylmercaptopurine ribonucleoside.

Partition Chromatography on Starch of Ribonucleosides

Nature, 1948
DURING work on ribonucleic acid turnover with nitrogen-15 in this Department, we found it necessary to isolate the different nitrogen-containing substances from small amounts of ribonucleic acid. It was thought that partition chromatography on starch as introduced by Elsden and Synge1 might give a possible solution to our problem. Vischer and Chargaff2

An analytical method for the separation of sugar-methylated ribonucleosides from base-methylated and nonmethylated ribonucleosides

Analytical Biochemistry, 1972
Abstract A paper chromatographic method for the separation of 2′- O -methylated ribonucleosides from nonmethylated and base-methylated ribonucleosides, using paper impregnated with ammonium borate and a butanol/borate developing solvent, is presented.

Interrogating the transcriptome with metabolically incorporated ribonucleosides

Molecular Omics, 2021
Abstract RNA is a central player in biological processes, but there remain major gaps in our understanding of transcriptomic processes and the underlying biochemical mechanisms regulating RNA in cells. A powerful strategy to facilitate molecular analysis of cellular RNA is the metabolic incorporation of chemical probes. In this review,

Purine Ribonucleoside and Deoxyribonucleoside Metabolism in Thymocytes

1980
The human deficiencies of adenosine deaminase and purine nucleoside phosphorylase activities are associated with an accumulation of the purine deoxyribonucleoside triphosphates, dATP (1–4) and dGTP (4) respectively. In the absence of adenosine deaminase or purine nucleoside phosphorylase activities, deoxyadenosine or deoxyguanosine are presumed to be ...

Degradation of pyrimidine ribonucleosides by Pseudomonas aeruginosa

Antonie van Leeuwenhoek, 1996
Pyrimidine ribonucleoside degradation in the human pathogen Pseudomonas aeruginosa ATCC 15692 was investigated. Either uracil, cytosine, 5-methylcytosine, thymine, uridine or cytidine supported P. aeruginosa growth as a nitrogen source when glucose served as the carbon source.
