Growth signalling networks that use glycerophospholipid metabolites as second messengers have been well characterized, but less is known of the second messengers derived from sphingolipids, another major class of membrane lipids. A tantalizing link between sphingolipids and cellular proliferation has emerged from the discovery that the sphingolipid metabolites sphingosine and sphingosine-1-phosphate stimulate growth of quiescent Swiss 3T3 fibroblasts by a pathway that is independent of protein kinase C. Sphingosine-1-phosphate is rapidly produced from sphingosine and may mediate its biological effects. Furthermore, sphingosine-1-phosphate triggers the dual signal transduction pathways of calcium mobilization and activation of phospholipase D, prominent events in the control of cellular proliferation. Here we report that activation of sphingosine kinase and the formation of sphingosine-1-phosphate are important in the signal transduction pathways activated by the potent mitogens platelet-derived growth factor (PDGF) and fetal calf serum (FCS).
