pubmed:abstractText
Prostaglandin production and cAMP formation are two signaling pathways identified for IL-1, though neither adequately account for the multitude of effects of IL-1. To investigate the role of tyrosine phosphorylation in IL-1 signaling, we used the tyrosine kinase inhibitor, genistein. At 10-30 micrograms/ml, genistein blocked IL-1 stimulated prostaglandin production and induction of prostaglandin endoperoxide synthase (PES) in glomerular mesangial cells maintained in 10% serum. Addition of genistein hours after IL-1 addition also halted further PGE2 synthesis. Genistein failed to block PES activity in vitro, indicating it was not acting as a PES inhibitor. Overall these data suggest that tyrosine phosphorylation may be a required event for IL-1 stimulation of PGE2 and PES activity, either directly as part of IL-1 signaling, or indirectly as part of a serum/PDGF competence effect on mesangial cells.
