Involvement of MAPKs and PLC Pathways in Modulation of Pacemaking Activity by So-Cheong-Ryong-Tang in Interstitial Cells of Cajal from Murine Small Intestine

Figure 5

Effects of SCRT on phospholipase C inhibitors in cultured ICCs. (a) SCRT (30 mg/mL) induced membrane depolarizations on ICCs. (b) U-73122 (5 μM), a phospholipase C inhibitor, abolished the generation of pacemaker potentials. U-73122 blocked the SCRT-induced (30 mg/mL) membrane depolarizations. (c) The application of U-73343 (5 μM) did not show any influence on the generation of pacemaker currents. Also, U-73343 did not block the SCRT-induced (30 mg/mL) membrane depolarizations. (d) The responses to SCRT in phospholipase C inhibitors are summarized in (d). Bars represent mean values ± SEs. . Significantly different from untreated controls. CTRL: Control.
