Hepatic infection by thymidine kinase-positive and thymidine kinase-negative herpes simplex virus after partial hepatectomy.
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...
متن کاملHuman Thymidine Kinase
Cytosolic thymidine kinase (EC 2.7.1.21) has been purified 5200-fold to apparent homogeneity from normal human placenta. The purification includes sequential affinity chromatography on blue-Sepharose and a thymidine column. The molecular weight of the enzyme determined by gel filtration and sucrose density ultracentrifugation is 92,000. The subunit molecular weight is 44,000, suggesting that t...
متن کاملPlaque autoradiography assay for the detection and quantitation of thymidine kinase-deficient and thymidine kinase-altered mutants of herpes simplex virus in clinical isolates.
A plaque autoradiography assay to detect and quantitate thymidine kinase (TK) mutants of herpes simplex virus type 1 (HSV-1) and HSV-2 in clinical samples is described. This method utilizes the selective incorporation of [125I]iododeoxycytidine, a pyrimidine analog selectively phosphorylated by the HSV TK. Only cells infected with TK-competent virus will efficiently incorporate iododeoxycytidin...
متن کاملFeedback Inhibition of Thymidine Kinase by Thymidine Triphosphate.
That the regulation of cell division and deoxyribonucleic acid synthesis is subject to some kind of chemical control in higher organisms is widely accepted (2-5). Davidson (2) has suggested that deoxyribonucleic acid synthesis takes place at critical concentrations of the deoxyribonucleoside triphosphates and that these compounds are components of a homeostatic mechanism. There are now at least...
