To further clarify the complex transcriptional regulation of the human GM-CSF gene , which was extensively investigated in activated T cells , we have studied the role of an upstream NF-kappaB like site in the 5637 non-lymphoid cell line , which derives from a bladder carcinoma and constitutively produces GM-CSF .
 ( protein: GM-CSF, None) , ( cell type: activated T cells, None) , ( DNA: NF-kappaB like site, None) , ( cell line: 5637 non-lymphoid cell line, None) , ( protein: NF-kappaB, None) , ( DNA: human GM-CSF gene, None) 
Locate the role in the text that participated in the event based on the event type and return it in the event list. 
 Option: Event type: RNA,cell type,protein,cell line,DNA, Arguments type: .
