Mechanisms of 2'-deoxyguanosine toxicity in mouse T-lymphoma cells with purine nucleoside phosphorylase deficiency and resistance to inhibition of ribonucleotide reductase by dGTP.
Purine nucleoside phosphorylase (PNP; EC 2.4.2.1) deficiency is thought to cause T-lymphocyte depletion by accumulation of dG and dGTP, resulting in feedback inhibition of ribonucleotide reductase (RR; EC 1.17.4.1) and hence DNA synthesis. To test for additional toxic mechanisms of dG, we selected a...
