Transient cotransfection of tat cDNA in sense orientation ( tat/S ), together with a plasmid containing the c-fos promoter ( FC3 , from- 711 to +42 ) in front of the bacterial chloramphenicol acetyltransferase (CAT) gene significantly enhanced CAT activity in Jurkat cells activated by the addition of 15% fetal calf serum ( FCS ) or 5 micrograms/mL phytohemagglutinin plus 10(-7) mol/L phorbol myristate acetate ( PMA ) and U937 cells activated by 15% FCS or 10(-7) mol/L PMA .
