Thymidine (Thd) was phosphorylated to dTTP also at 0°C, both in Ehrlich ascites tumor cells and human tonsillar lymphocytes, but was not incorporated into DNA. The uptake and phosphorylation of 14C-Thd into the pool showed regular kinetics (Km 6, 6

Utilisation of exogenous (ribo)cytidine (3H-CR) and deoxyribocytidine (3H-CdR) for DNA/RNA synthesis and for activation of phospholipid intermediates was compared in human tonsillar lymphocytes. Incorporation of 3H-CdR into dCDP-choline and into dCDP

Extracellular deoxycytidine (CdR) was previously shown to be salvaged into water soluble [1] and also into lipidic [2] precursors of phospholipids in stimulated lymphocytes and in lymphoma cells [3]. In this paper we have described that non-dividing

In addition to the water-soluble deoxyliponucleotides (Spasokukotskaja et al. (1988), Biochem. Biophys. Res. Commun. 155, 923), a lipid compound was shown to be labeled from external 3H-deoxycytidine (5-3H-CdR) in infant tonsillar lymphocytes. Chlorp

Peanut agglutinin (PNA), a d -galactose specific lectin, agglutinated 10–18% of lymphocytes isolated from tonsils of 3- to 6-yr-old children. PNA + cells were found to be mainly B lymphocytes showing a 9.6 times higher specific activity of DNA poly

dCTP formed from exogenous deoxycytidine via the salvage pathways was previously shown to serve deoxyliponucleotide synthesis in lymphocytes (Spasokukotskaja et al, Biochem. Biophys. Res. Commun. (1988) 155, 923–929) and now in lymphoma cells. Afte

The DNA synthesis system of freshly isolated tonsillar lymphocytes and those stimulated by phytohaemagglutinin were compared by different methods. Both cell populations had high DNA polymerase α and thymidine kinase activities, as well as a high rat

High (HD) and low (LD) density cells were separated on 25% BSA gradient from tonsils of 3-6 years old children. Early B lymphocyte markers and sIg-s were found on the surface of 59-82% of the LD cells. This cell population was 5-6 times more active i

The effect of ATP on Escherichia coli DNA polymerase I has been investigated as a function of the concentration of substrates and divalent metal ions in the presence of activated DNA as template. At saturating Mg2+ concentration 1.5 mM ATP stimulated

Cellular [ 3 H]uridine uptake and incorporation into RNA were compared in human tonsil lymphocyte subpopulations obtained by separation on nylon-wool column. While the nonadherent subpopulation, Fraction I, contained 74.5 ± 8% E-rosette forming T-ly
