Assessment of Thymidine Phosphorylase Function: Measurement of Plasma Thymidine (and Deoxyuridine) and Thymidine Phosphorylase Activity [PDF]

open access: yes, 2011
We describe detailed methods to measure thymidine (dThd) and deoxyuridine (dUrd) concentrations and thymidine phosphorylase (TP) activity in biological samples. These protocols allow the detection of TP dysfunction in patients with mitochondrial neurogastrointestinal encephalomyopathy (MNGIE).

Fission yeast strains with circular chromosomes require the 9-1-1 checkpoint complex for the viability in response to the anti-cancer drug 5-fluorodeoxyuridine. [PDF]

open access: yesPLoS ONE, 2017
Thymidine kinase converts 5-fluorodeoxyuridine to 5-fluorodeoxyuridine monophosphate, which causes disruption of deoxynucleotide triphosphate ratios.

THYMIDINE DEGRADATION PRODUCTS IN PLANT TISSUES LABELED WITH TRITIATED THYMIDINE [PDF]

open access: yesThe Journal of Cell Biology, 1963
A study of the metabolic pathways of H3-thymidine utilization in buds of Lilium longiflorum and root tips of Vicia faba was undertaken in order to obtain information that might explain the binding of H3 from H3-thymidine in the cytoplasm of these plants.

Hydrogen Peroxide-Induced Thymidine Incorporation Into Cultured Rat Astrocytes

open access: yesJournal of Pharmacological Sciences, 2006
We characterized [methyl-3H]thymidine ([3H]thymidine) and [5-3H]uridine ([3H]uridine) incorporation into cultured astrocytes and neurons in the presence and absence of hydrogen peroxide (H2O2) in order to define the response to oxidative stress in the ...

Incorporation of thymidine into onion root meristematic cell nuclei in presence of hydroxyurea and its role in recovery of mitotic activity

open access: yesActa Societatis Botanicorum Poloniae, 2015
Hydroxyurea treatment of onion roots induced mitotic block which was released by transfer of bulbs to water, and also to some extent by addition of cold or 3H-thymidine to hydroxyurea solutions.
