Tetradecanoylphorbol Acetate 14-17 cyclin dependent kinase 1 Homo sapiens 49-56 8187833-4 1994 Treatment of HeLa cells (synchronized around the G2-M transition) with TPA (10(-7) M) has now been shown to induce an overall decrease of the histone H1 kinase activity associated with anti-p34cdc2 immunoprecipitates after about 20 to 30 min. Tetradecanoylphorbol Acetate 71-74 cyclin dependent kinase 1 Homo sapiens 190-197 8187833-8 1994 However, p34cdc2 from cultures treated with TPA was more intensely stained by anti-phosphotyrosine antibodies than that of control cells, indicating that TPA treatment probably prevented the tyrosine dephosphorylation required for expression of the histone H1 kinase activity of the complex. Tetradecanoylphorbol Acetate 44-47 cyclin dependent kinase 1 Homo sapiens 9-16 8187833-8 1994 However, p34cdc2 from cultures treated with TPA was more intensely stained by anti-phosphotyrosine antibodies than that of control cells, indicating that TPA treatment probably prevented the tyrosine dephosphorylation required for expression of the histone H1 kinase activity of the complex. Tetradecanoylphorbol Acetate 154-157 cyclin dependent kinase 1 Homo sapiens 9-16 8187833-9 1994 The results indicate that TPA treatment of HeLa cultures rapidly stops the G2-M transition because it very rapidly prevents the p34cdc2/Cyclin B complex in G2 cells from developing histone H1 kinase activity.
