Using transcription analysis , such as multiplex messenger assays , we show here that natural cytotoxicity exerted by the human NKL cell line correlates with mRNA accumulation of very early activator protein (AP)-1 transcription factor genes such as JunB , FosB and c-Fos .
 ( DNA: JunB, None) , ( protein: very early activator protein (AP)-1, None) , ( cell line: human NKL cell line, None) , ( DNA: FosB, None) , ( DNA: c-Fos, None) , ( DNA: transcription factor genes, None)
