Double-stimulation was used to demonstrate that, in a T lymphocytic cell line ( CEM ), phorbol myristate acetate ( PMA ) rapidly induced NF-kappa B through a signaling pathway which did not involve reactive oxygen species ( ROS ) and was different from the activation triggered by either H2O2 or tumor necrosis factor-alpha ( TNF-alpha ).
 ( cell line: CEM, None) , ( protein: NF-kappa B, None) , ( protein: TNF-alpha, None) , ( cell line: T lymphocytic cell line, None) , ( protein: tumor necrosis factor-alpha, None)
