Treatment of bovine lymph node lymphocytes with the tumor promoter, 12-O-tetradecanoyl phorbol-13-acetate (TPA) leads to depressed [3H]thymidine incorporation in response to phytohemagglutinin (PHA). Radioautographic and morphological analyses showed that depression was at the level of blast-cell formation. Isotope-dilution experiments, and the use of [3H]deoxycytidine to label DNA indicated that the inhibition was not due to a block in thymidine transport in the treated cells. These experiments, as well as a bioassay designed to measure thymidine in the culture medium, showed that the apparent inhibition of [3H]thymidine incorporation and DNA synthesis was not the result of production of cold thymidine in the cultures. The results taken together support the idea that most TPA-treated cells are inhibited from responding to the mitogenic lectins. Those cells which do respond appear to form blast cells and synthesize DNA at the same rate as do untreated cells.
