The effects of the intracellular Ca+2antagonist TMB-8 on the amiloride-sensitive Na+influx pathway in human fibroblasts was investigated. It was found that TMB-8 inhibits serum- or growth factor-stimulated Na+influx in a dose dependent fashion with a Ki value = 15 μM. A23187-stimulated Na+influx on the other hand, was not inhibited by TMB-8. Furthermore, serum-stimulated Na+influx could also be blocked by the calmodulin antagonist W-13. These results suggest that serum- or growth factor-stimulated Na+influx is associated with an elevation of cytosolic free Ca+2levels, which then combine with calmodulin to activate the amiloride-sensitive Na+influx pathway.
