title: Response to IL-6 stimulation of human hepatoblastoma cells: production of pancreatic secretory trypsin inhibitor.
abstract: LPS-stimulated macrophage conditioned medium and IL-6 markedly stimulated the secretion of PSTI by cultured hepatoblastoma cells. The mechanism underlying the cellular response of IL-6-induced secretion of PSTI was investigated. Among the agents affecting the signal transduction pathways, forskolin significantly induced PSTI secretion whereas PMA or A23187 did not, suggesting that IL-6 induced PSTI secretion is mediated by cAMP dependent protein kinase A.
