We have previously reported that 5'-aminothymidine (5'-AdThd), an antagonist of the feedback inhibition exerted by dTTP that regulates thymidine kinase, enhances the uptake and cytotoxicity of 5-iododeoxyuridine in various human bladder cancer cell lines but not in normal human urothelial cells (HU) propagated in vitro. In this work we have analyzed the factors that could potentially account fo...
Herpes simplex virus (HSV) infection of mouse liver after partial hepatectomy was studied. Partial hepatectomy resulted in the rapid onset of cellular DNA synthesis and the appearance of many mitotic figures (peak, 3 days after surgery). Similar changes were not seen in control animals. After partial hepatectomy, the mice were infected with thymidine kinase-positive (TK+) and -negative (TK-) HS...
Thymidine is an important precursor in the production of various antiviral drugs, including azidothymidine for the treatment of AIDS. Since thymidine-containing nucleotides are synthesized only by the de novo pathway during DNA synthesis, it is not easy to produce a large amount of thymidine biologically. In order to develop a host strain to produce thymidine, thymidine phosphorylase, thymidine...
