At least in the case of the IL1B promoter , repression did not seem to involve another factor whose activity is affected by the NSAIDs , NFkappaB as the IL1B promoter fragment used in our studies is not NFkappaB responsive and binds specifically to HSF1 .
 ( DNA: IL1B promoter, None) , ( protein: NFkappaB, None) , ( protein: HSF1, None) , ( protein: NFkappaB, None) , ( DNA: IL1B promoter fragment, None) , ( DNA: IL1B promoter, None)
