Cell Synchronization by Double Thymidine Block.

open access: yesBio-protocol, 2018
Cell synchronization is widely used in studying mechanisms involves in regulation of cell cycle progression. Through synchronization, cells at distinct cell cycle stage could be obtained.

Thymidine Catabolism as a Metabolic Strategy for Cancer Survival

open access: yesCell Reports, 2017
Thymidine phosphorylase (TP), a rate-limiting enzyme in thymidine catabolism, plays a pivotal role in tumor progression; however, the mechanisms underlying this role are not fully understood.

Nitrogen and carbon limitation of planktonic primary production and phytoplankton–bacterioplankton coupling in ponds on the McMurdo Ice Shelf, Antarctica

open access: yesEnvironmental Research Letters, 2013
We compared planktonic primary and secondary production across twenty meltwater ponds on the surface of the McMurdo Ice Shelf in January 2007, including some ponds with basal brines created by meromictic stratification.

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.

Optimisation of the lymphocyte proliferation assay in rainbow trout (Oncorhynchus mykiss)

open access: yesVeterinární Medicína, 2019
The lymphocyte proliferation assay is a valuable method used for the evaluation of the fish immune system. However, there are many variations and optimal results are not always obtained.

A critical examination of substoichiometric isotope dilution analysis using thymidine and leucine

open access: yesScientia Marina, 1999
Isotope dilution analysis is used to determine the specific activity of radiolabelled precursors such as 3H-thymidine and 3H-leucine incorporated into DNA or protein in environmental samples.

Can plasma antioxidants prevent DNA damage in oxidative stress condition induced by growth hormone deficiency? A pilot study.

open access: yesPLoS ONE, 2021
Adult growth hormone deficiency (GHD), a condition characterized by increased oxidative stress, is related to augmented cardiovascular, metabolic and oncological risk. A case-control observational study has been performed to evaluate DNA oxidative damage

Inhibitory Effect of Bridged Nucleosides on Thermus aquaticus DNA Polymerase and Insight into the Binding Interactions. [PDF]

open access: yesPLoS ONE, 2016
Modified nucleosides have the potential to inhibit DNA polymerases for the treatment of viral infections and cancer. With the hope of developing potent drug candidates by the modification of the 2',4'-position of the ribose with the inclusion of a bridge,

Unbiased metabolite profiling indicates that a diminished thymidine pool is the underlying mechanism of colon cancer chemoprevention by alpha-difluoromethylornithine.

open access: yesCancer Discovery, 2013
UNLABELLED The ornithine decarboxylase inhibitor α-difluoromethylornithine (DFMO) is a highly effective chemopreventive agent for colorectal cancer thought to act via polyamine depletion. However, in DFMO-treated patients, mucosal polyamine levels do not
