Here we report an analysis of the transcription factor families AP-1, Sp1, NF-kappaB , and signal transducers and activators of transcription ( STAT ) in cancer patients' lymphocytes before and after IL-2 immunotherapy , as assessed by a gel-shift assay .
 ( protein: STAT, None) , ( protein: IL-2, None) , ( protein: NF-kappaB, None) , ( cell type: lymphocytes, None) , ( protein: signal transducers and activators of transcription, None) , ( cell type: cancer patients#$%# lymphocytes, None)
