This effect was specifically due to Tat , since Jurkat and U937 cells cotransfected either with tat cDNA in antisense orientation ( tat/AS ), tat carrying a mutation in the aminoacid cys22-gly22 ( tat 22/S ) or with the backbone vector alone ( pRPneo-SL3 ) did not show any significant difference in c-fos promoter activity as compared to cells transfected with FC3 plasmid alone.
