Thus, through the differential use of the same promoter element , the composite kappa 3/CRE site , the TNF-alpha gene is regulated in a cell-type-specific manner in response to the same extracellular signal .
 ( DNA: promoter element, None) , ( protein: TNF-alpha, None) , ( DNA: composite kappa 3/CRE site, None) , ( DNA: TNF-alpha gene, None)
