Treatment of quiescent Swiss 3T3 cells with bombesin induces a rapid (≤40 s) and transient increase in the kinase activity of the Src family of tyrosine kinases, as determined by autophosphorylation in immune complex kinase assays (4.6 ± 0.2-fold stimulation, n = 44) and phosphorylation of exogenous substrates. Phorbol 12,13-dibutyrate increased the activity of Src family kinases with similar kinetics but was less effective than bombesin. However, Src family kinase activation by bombesin is not dependent either on protein kinase C or Ca2+. Bombesin stimulation of Src family kinase activity could also be dissociated from p125 focal adhesion kinase tyrosine phosphorylation. Neither treatment with cytochalasin D nor placement of the cells in suspension prevented the stimulation of Src family kinase activity induced by bombesin, but both abolished bombesin-induced tyrosine phosphorylation of p125 focal adhesion kinase. The stimulation of the Src family kinase activity by bombesin was completely prevented by treatment with vanadate, a potent inhibitor of protein-tyrosine phosphatases. Bradykinin and vasopressin also stimulated Src family kinase activity transiently, and this stimulation was also inhibited by vanadate. Our results dissect two separate pathways that lead to protein tyrosine phosphorylation in neuropeptide-stimulated Swiss 3T3 cells.
