The short-term incubation of rat thymocytes with 12-O-tetradecanoylphorbol-13-acetate (TPA) resulted in a significant increase in sialyltransferase (S-T) activity and a decrease in terminal deoxyribonucleotidyl transferase (TdT) activity. The ratio of peanut agglutinin (PNA)-positive cells and of TdT-positive cells in TPA-treated cells also decreased. However, TPA had no significant effects on the viability, morphology, DNA synthesis, and DNA polymerase alpha activity of the cells. More marked changes were observed by incubating a non-T, non-B human lymphoid leukaemia cell line with TPA. Similar findings were also noted in TPA-treated mouse thymocytes. These changes may represent an aspect of TPA-induced differentiation of murine thymocytes.
