Structural Basis for the Dual Thymidine and Thymidylate Kinase Activity of Herpes Thymidine Kinases [PDF]

open access: yesStructure, 2003
Crystal structures of equine herpesvirus type-4 thymidine kinase (EHV4-TK) in complex with (i). thymidine and ADP, (ii). thymidine and SO(4) and the bisubstrate analogs, (iii). TP(4)A, and (iv). TP(5)A have been solved. Additionally, the structure of herpes simplex virus type-1 thymidine kinase (HSV1-TK) in complex with TP(5)A has been determined ...

Tk-deleted pseudorabies virus retains high pathogenicity in rats

open access: yesJournal of Veterinary Research, 2021
The pseudorabies virus (PRV) gene encoding thymidine kinase (tk) is an important virulence-associated factor. Attenuation of PRV in susceptible animals is a frequent result of tk deletion.

Thymidine kinase in breast cancer [PDF]

open access: yesBritish Journal of Cancer, 1990
The enzyme thymidine kinase is associated with DNA synthesis. Thymidine kinase serum levels were studied in normal controls (n = 20), patients with primary breast cancer (n = 60), patients with systemic breast cancer (n = 20) and as a non-cancer disease control group in patients with inflammatory gastrointestinal disorders (n = 20).

Mitochondrial DNA Depletion Syndrome

open access: yesPediatric Neurology Briefs, 2002
Twenty patients with myopathic mitochondrial DNA (mtDNA) depletion syndrome (MDS) were screened for mutations in thymidine kinase 2 (TK2) and deoxyguanosine kinase (dGK) genes at Columbia University, New York, NY.

Dexamethasone pretreatment impairs the thymidylate synthase inhibition mediated flare in thymidine salvage pathway activity in non-small cell lung cancer. [PDF]

open access: yesPLoS ONE, 2018
INTRODUCTION:Successful inhibition of thymidylate synthase (TS) by pemetrexed, a TS inhibitor, results in a reproducible transient burst or "flare" in thymidine salvage pathway activity at 2 hrs.

Efficacy and Safety of Doubly-Regulated Vaccinia Virus in a Mouse Xenograft Model of Multiple Myeloma

open access: yesMolecular Therapy: Oncolytics, 2017
Multiple myeloma is a malignancy of plasma cells of the bone marrow. Although the prognosis is variable, no curative therapy has been defined. Vaccinia virus infects cancer cells and kills such cells in a variety of ways.

INDUCIBILITY OF THYMIDINE KINASE BY THYMIDINE AS A FUNCTION OF INTERPHASE STAGE [PDF]

open access: yesThe Journal of Cell Biology, 1965
Thymidine may act as an inducer of thymidine kinase activity in cells of higher plants. The general response is demonstrable in a randomly developing cell population such as is found in germinating wheat embryos. If a synchronously developing cell population is studied, however, potentially inducible cells are found to be susceptible to the inductive ...

Differential expression of enzymes in thymidylate biosynthesis in zebrafish at different developmental stages: implications for dtymk mutation-caused neurodegenerative disorders

open access: yesBMC Neuroscience, 2022
Background Deoxythymidine triphosphate (dTTP) is an essential building block of DNA, and defects in enzymes involved in dTTP synthesis cause neurodegenerative disorders.

Feedback inhibition of thymidine kinase by thymidine triphosphate

open access: yesExperimental Cell Research, 1963
THE search for rate-controlling enzyme systems in the overall synthesis of DNA has led a number of investigators to study the reactions in the sequence from Tdr to dTTP. Little duplication of effort has occurred despite the similarity in overall objectives.

Thymidine Kinase in IDU Resistance.

open access: yesExperimental Biology and Medicine, 1965
SummaryStudies were done to determine whether 5-iodo-2′-deoxyuridine resistance of herpes simplex in rabbit corneal infection was a function of thymidine kinase deficiency in the viral genome. Herpes simplex virus passed in rabbit kidney cells in the presence of 5-iodo-2′-deoxyuridine was resistant to it in vivo although this resistant virus induced ...
