Abstract excerpt

We have previously demonstrated that 12-O-tetradecanoylphorbol-13-acetate (TPA) activates human T-cell leukemia virus type-I long terminal repeat (LTR) in Jurkat cells by a protein kinase C (PKC)-independent mechanism involving a posttranslational activation of Sp1 binding to an Sp1 site located within the Ets responsive region-1 (ERR-1). By employing the PKC inhibitor, bisindolylmaleimide I and cotransfecting...
