IN the course of a series of experiments designed to test for possible anomalies in the synthesis and behaviour of chromosomal deoxyribonucleic acid resulting from the use of tritiated thymidine, the possibility arose that the tritiated precursor could interfere with the normal course of synthesis and partition by destroying the integrity of the ...

Long-distance neuronal migration in the adult mammalian brain.
Science, 1994During the development of the mammalian brain, neuronal precursors migrate to their final destination from their site of birth in the ventricular and subventricular zones (VZ and SVZ, respectively).

The association of thymidine kinase activity and thymidine transport in Escherichia coli
Gene, 1991We have constructed a series of mutants within the putative nucleoside-binding site of the herpes simplex type-1 virus (HSV-1) thymidine kinase (TK)-encoding gene (tk), contained within an expression vector. While most mutations within this sequence produce an inactive protein, we find no absolute requirement for the wild-type Ile166 and Ala167.

A test system allowing the estimation of the dT phosphorylating enzyme activity of one Acetabularia cell and of singular cell parts was developed. The occurrence in Acetabularia of a true dT kinase (EC. 2. 7. 1. 75) was demonstrated.

Secretion of Thymidine by Hybridoma Cells [PDF]
, 2006 Hybridoma cells secrete a factor (referred to in the following as ITI: inhibitor of radioactive thymidine incorporation) which inhibits incorporation of radioactive thymidine into cells 1. Of other cells tested, only myeloma cells were found to secrete ITI 2.

A pyrimidine nucleoside phosphorylase was partially purified from human blood platelets. The purified enzyme, as well as crude enzyme preparations, catalyses the phosphorolysis of thymidine and deoxyuridine, but not of uridine, and is able to catalyse direct pentosyl transfer from these deoxyribonucleosides to uracil or thymine; this enzyme has the ...

We present a simple, fast and validated method for the determination of the two nucleosides thymidine (dThd) and deoxyuridine (dUrd) in plasma of patients with symptoms suggestive of mitochondrial neurogastrointestinal encephalomyopathy (MNGIE), using high performance liquid chromatography coupled with ultraviolet spectrophotometric detection (HPLC-UV).
