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.
 DNA: c-fos promoter; cell line: Jurkat; DNA: tat/AS; DNA: tat cDNA; DNA: tat 22/S; protein: aminoacid cys22-gly22; DNA: pRPneo-SL3; protein: Tat; DNA: FC3 plasmid; DNA: tat; DNA: backbone vector alone; cell line: U937 cells
Given options, please tell me the categories of all the listed entity words.Output format is "type1: word1; type2: word2".
