Friend erythroleukemic cells were induced to differentiate by dimethylsulfoxide (Me2SO) in the absence or presence of the tumor promoter 12-O-tetradecanoyl-phorbol 13-acetate. The effects of the latter on the molecular parameters related to globin mRNA metabolism were examined. When differentiation was scored by benzidine staining, it had an inhibitory effect on Me2SO-treated cells. On the other hand, when differentiation was followed by determination of globin mRNA accumulation, it had a pleiotropic effect on Me2SO-treated cells. At the early phase of differentiation (2--3 days) the rate of globin mRNA accumulation was higher in the promoter-treated cells than in the control. This unexpectedly high level of accumulation was followed by a sharp reduction and most of the globin RNA sequences disappeared at later stages of differentiation (days 4--5). The reduction can be related to the effect of the promoter on the stability of globin RNA in the cytoplasm which was reduced from a half-life of 16 h to that of 8 h only. Other parameters, such as the rate of globin mRNA synthesis and its capability to serve as a template for cell-free protein synthesis were not affected by treatment with the promoter throughout the differentiation process.
