Activation of BKCa by membrane stretch in rat colonic SMCs. (a) The pressure-dependent activation of BKCa channels was recorded from a cell-attached patch. The patches were held at +60 mV. (b) The expanded data show the amplitude of the single-channel current was not changed compared with that in other panels (C: closed state). (c) Statistical data of BKCa channel open probability (NPo) challenged by negative pressure on cell-attached patch. Values are shown as means ± SEM, n = 5; ∗ P < 0.05 versus control group; ∙ P < 0.05 versus −30 mmHg group.
