Active PLC inhibitor U-73122 blocking the gintonin action on P2X1 receptor desensitization. (A) Representative trace showing the gintonin-mediated IATP potentiation in Xenopus oocytes expressing human P2X1 receptors. (B, C) Representative trace showing the effects of active (U73122) and inactive (U73343) PLC inhibitors (each 1 μM) on the gintonin-mediated IATP potentiation. The active PLC inhibitor (1 μM) blocks both gintonin-evoked CaCC and IATP potentiation. (D) Histograms summarizing the effects of the active or inactive PLC inhibitors on gintoninmediated IATP potentiation (*p < 0.001, compared to control). Data represent the mean ± SEM (n = 5/group).
