Pretreatment with the broad serine /threonine kinase inhibitor staurosporine partly blocked the calyculin A -induced STAT3 phosphorylation , whereas inhibitors of serine /threonine kinases , such as mitogen-activated protein kinase-1 extracellular-regulated kinase-kinase , mitogen-activated protein p38 kinase , and phosphatidylinositol 3-kinase , did not.
