Thymidine kinase and deoxycytidine kinase in HIV-infected children.
It has been demonstrated that HIV infection may affect the levels of thymidine kinase (TK) and deoxycytidine kinase (dCK) in peripheral blood mononuclear cells from HIV infected adults. The aim of this study was to examine the effect of HIV infection and/or antiretroviral therapy on the activity of the above enzymes in HIV-infected children. The results showed that an inter-individual variabili...
متن کاملDeoxypyrimidine monophosphate bypass therapy for thymidine kinase 2 deficiency
Autosomal recessive mutations in the thymidine kinase 2 gene (TK2) cause mitochondrial DNA depletion, multiple deletions, or both due to loss of TK2 enzyme activity and ensuing unbalanced deoxynucleotide triphosphate (dNTP) pools. To bypass Tk2 deficiency, we administered deoxycytidine and deoxythymidine monophosphates (dCMP+dTMP) to the Tk2 H126N (Tk2(-/-)) knock-in mouse model from postnatal ...
متن کاملEvolution of herpesvirus thymidine kinases from cellular deoxycytidine kinase.
The thymidine kinases encoded by herpesviruses of higher vertebrates form a distinct group and are unrelated to the thymidine kinases (TKs) of other organisms. Their evolutionary source has not been identified, but our analysis has revealed a clear relationship with a sequence of human deoxycytidine kinase (dCK) published recently. We report the sequence of the putative TK of channel catfish vi...
متن کاملDeoxycytidine and deoxythymidine kinase activities in plasma of mice and patients with neoplastic disease.
In C57BL x DBA/2 F1 (hereafter called BD2F1) mice inoculated with P815 neoplasms and in AKR mice with spontaneously developing leukemia, significant amounts of plasma deoxycytidine and thymidine kinase activities were detected in advanced disease. Undetectable or low levels of such kinase activities were observed in normal BD2F1 and in control AKR mice. Initial studies with leukemia patients re...
متن کاملMetabolism of deoxycytidine, thymine, and deoxythymidine in the hamster.
The ability of growing and of mature Syrian hamsters to anabolize (to liver DNA) or catabolize (to 14CO2) graded amounts of [2-14C]deoxythymidine (TdR), thymine, or deoxycytidine (CdR) was measured in vivo. Of the three precursors, CdR labeled DNA most efficiently and, as expected, incorporation of all three into DNA was greater in younger animals. The catabolism of [2-14C]CdR to respired 14CO2...
