NF-kappa B -directed luciferase activity increased approximately 3-fold when cells transfected with the plasmid pNF-kappa BLUC containing five copies of consensus NF-kappa B site linked to a minimal adenovirus E1B promoter-luciferase gene were exposed to thrombin , indicating that activation of NF-kappa B was essential for thrombin response .
