Protein kinase calpha but not p44/42 mitogen-activated protein kinase, p38, or c-Jun NH(2)-terminal kinase is required for intercellular adhesion molecule-1 expression mediated by interleukin-1beta: involvement of sequential activation of tyrosine kinase, nuclear factor-kappaB-inducing kinase, and IkappaB kinase 2.

Abstract excerpt
IL-1beta induced an increase in ICAM-1 expression in human A549 epithelial cells and immunofluorescence staining confirmed this result. Tyrosine kinase inhibitors (genistein or tyrphostin 23) or phosphatidylcholine-specific phospholipase C inhibitor (D609) attenuated IL-1beta-induced ICAM-1 expression. IL-1beta produced an increase in PKC activity and this effect was abolished by D609. PKC inhibitors...
