1 After a longer, 20-h treatment with PMA (20 nM), a considerable portion of PKC was still membrane-associated, and the total amount of immunoreactive PKC was not reduced considerably. Tetradecanoylphorbol Acetate protein kinase C alpha Homo sapiens
2 After a longer, 20-h treatment with PMA (20 nM), a considerable portion of PKC was still membrane-associated, and the total amount of immunoreactive PKC was not reduced considerably. Tetradecanoylphorbol Acetate protein kinase C alpha Homo sapiens
3 We propose that Bryo inhibits PMA-induced T cell proliferation by causing rapid degradation of PKC, reflecting a requirement of persistent PKC stimulation (lasting approximately 48 h) for the activation of human T cells and progression through the cell cycle. Tetradecanoylphorbol Acetate protein kinase C alpha Homo sapiens
