By voltage-clamp recording, we show a novel inward current which oscillates after activation with bradykinin or serum in v-Ki-ras-transformed NIH 3T3 cells. The current oscillation was infrequently observed in control NIH 3T3 fibroblasts. The same stimulation evokes Ca2+ oscillations in the ras-transformed cells but not in parental cells (Fu et al., FEBS Lett. 281, 263-266, 1991). The results suggest that the oscillatory currents are generated by influxes of divalent cations to maintain Ca2+ oscillations in ras-transformed NIH 3T3 cells.
