The nuclear factor interleukin-6 (NF-IL6) and signal transducer and activator of transcription-3 (STAT-3) signalling pathways co-operate to mediate the activation of the hsp90β gene by interleukin-6 but have opposite effects on its inducibility by heat shock

Abstract
The levels of the 90 kDa heat-shock protein (hsp90) and the activity of the hsp90β gene promoter are increased in response to treatment by interleukin
