|Abstract:||In two human cell lines, MDA-MB-231 and HeLa, the inducible expression of the interleukin-6 (IL-6) gene by two protein synthesis inhibitors, cycloheximide and anisomycin, was compared with the induction by the most potent physiological inducer of IL-6 described to date, interleukin-1-beta (IL-1-beta). In cycloheximide or anisomycin treated cells, the accumulation of the IL-6 message and the activation of transcription factors required for IL-6 gene expression occurs at an extent similar to that obtained with IL-1-beta. Furthermore, IL-6 mRNA accumulation stimulated by cycloheximide or anisomycin is almost completely inhibited in the presence of actinomycin D, indicating that this effect occurs mainly through the activation of the transcriptional machinery. These data indicate that transcriptional induction of the IL-6 gene by inhibitors of protein synthesis is triggered by the same nuclear signals as other inducers.|
