Triplet state studies of the nucleoside and nucleotide derivatives of uracil and thymine
Biochimica et Biophysica Acta (BBA) - Nucleic Acids and Protein Synthesis, 1972Abstract Transient absorbing species due to the triplet states of uridine, 5′-uridylic acid, thymidine and 5′-thymidylic acid have been studied by flash photolysis and compared with those of the triplet states of uracil and thymine. These transients are quenched by oxygen and by their ground states with bimolecular rate constants of 6 · 10 8 , 5 · 10

Glomerular uracil nucleotide synthesis: effects of diabetes and protein intake
American Journal of Physiology-Renal Physiology, 1988The biosynthesis of uridine 5'-triphosphate (UTP), uridine 5'-diphosphohexoses, and 5'-diphosphohexosamines (UDP-sugars) was studied in isolated rat glomeruli 48 h after streptozotocin-induced diabetes. Compared with control, diabetic glomeruli demonstrated an increase in the following: exogenous orotate utilization, orotate incorporation into UTP and

in vivo RNA structural probing of guanine and uracil nucleotides in yeast
2022Abstract RNAs have critical catalytic or regulatory functions in the cell and play significant roles in many steps of gene expression regulation. RNA structure can be essential for its cellular function. Therefore, methods to investigate the structure of RNA in vivo are of great importance for understanding the role ...

Concentration of uracil nucleotides and UDP-glucose in mouse liver after partial hepatectomy
International Journal of Biochemistry, 1978Abstract 1. 1. The UTP and UDP concentration of mouse liver was not significantly affected by the partial hepatectomy, whereas the size of the UMP pool increased 3- to 4-fold when compared to unoperated controls. 2. 2. In regenerating liver, the UDP-glucose concentration decreased by 20% or more when compared to unoperated controls. 3. 3.

The turnover of cardiac adenine and uracil nucleotides was studied in the hypertrophying rat heart by means of the kinetics of incorporation of labeled phosphate into the alpha-phosphate groups of nucleotides. Cardiac hypertrophy was induced either by chronic isoproterenol treatment (5 mg X kg-1 body wt. daily, s.c.) or by abdominal aortic constriction.
