Effect of Kv7 channel openers in PIP2- and Gβγ-depleted cells. Mean data showing action of Retigabine, S-1 and NS15370 in HEK293 Kv7.4 cells under various conditions (control, preincubated with wortmannin alone, preincubated with wortmannin + short (≤30 s) application of trypsin, preincubated with gallein). Currents after treatment with pan-Kv7 channel blocker linopirdine are shown for reference. *, **, *** and **** denote p < 0.05 – p < 0.0001, respectively, compared to controls
