In this study, we demonstrated that IL-6 regulation occurred exclusively at the transcriptional level and that the bimodal increase of junB mRNA and JunB protein can be accounted for by a biphasic stimulation of junB transcription .
 ( DNA: junB, None) , ( protein: IL-6, None) , ( RNA: junB mRNA, None) , ( protein: JunB protein, None)
