Bombesin, a peptide mitogen for a variety of cell types, acts as a typical Ca2+-mobilizing hormone in Swiss 3T3 fibroblasts. At its mitogenic concentrations (1-25 nM), bombesin stimulates polyphosphoinositide turnover, i.e. breakdown of phosphatidylinositol 4,5-bisphosphate and a concomitant increase in inositol phosphates in a time- and dose-dependent manner. In particular, bombesin induces an initial transient increase in inositol 1,4,5-trisphosphate concentration, followed by an increase in… Expand
