Abstract/OtherAbstract:
Pancreatic secretory trypsin inhibitor (PSTI) has been suggested to be an acute-phase reactant in humans and to be induced by inflammatory cytokines such as the interleukins IL-1 and IL-6. We report that PSTI is synthesized in hepatoma cells and that the gene expression is augmented by IL-6. The start points (tsp) for basal and augmented transcription are exactly the same as the tsp in normal pancreas. Analysis of the PSTI gene revealed that a 40-bp DNA fragment located between kb -3.84 and -3.80 carries the element responsible for both transcriptional activity and IL-6-induced gene expression. This 40-bp fragment contains TTGNNGNAATG, the consensus sequence for the NF-IL6-binding site, which is also known as the IL-6-responsive element that is conserved among various acute-phase genes. The basal activity was augmented by another sequence that lies between kb -4.0 and -3.9.
