1 PU.1, a member of the ets transcription factor family, has been previously shown to be necessary for tetradecanoylphorbol-13 acetate (TPA)-induced U937 leukemic cell maturation. Tetradecanoylphorbol Acetate Spi-1 proto-oncogene Homo sapiens
2 However, TPA treatment induced phosphorylation of PU.1. Tetradecanoylphorbol Acetate Spi-1 proto-oncogene Homo sapiens
3 Gel-shift analysis using a labeled PU.1 oligomer showed that TPA induced a unique PU.1 binding activity. Tetradecanoylphorbol Acetate Spi-1 proto-oncogene Homo sapiens
4 Gel-shift analysis using a labeled PU.1 oligomer showed that TPA induced a unique PU.1 binding activity. Tetradecanoylphorbol Acetate Spi-1 proto-oncogene Homo sapiens
5 The PU.1 binding activity was generated at TPA-13 concentrations stimulating growth arrest and was blocked by the PKC inhibitor GF109203X, which antagonized TPA-induced growth inhibition. Tetradecanoylphorbol Acetate Spi-1 proto-oncogene Homo sapiens
6 The PU.1 binding activity was generated at TPA-13 concentrations stimulating growth arrest and was blocked by the PKC inhibitor GF109203X, which antagonized TPA-induced growth inhibition. Tetradecanoylphorbol Acetate Spi-1 proto-oncogene Homo sapiens
7 These data suggest that TPA-induced growth inhibition is associated with phosphorylation of PU.1 and generation of a unique PU.1 binding activity. Tetradecanoylphorbol Acetate Spi-1 proto-oncogene Homo sapiens
8 These data suggest that TPA-induced growth inhibition is associated with phosphorylation of PU.1 and generation of a unique PU.1 binding activity. Tetradecanoylphorbol Acetate Spi-1 proto-oncogene Homo sapiens
