Role of BK_Ca in Stretch-Induced Relaxation of Colonic Smooth Muscle

Figure 1

Expression of B in smooth muscle tissues from different GI segments of rats. (a) and (b) Protein expression levels of B in GI tract. All values are shown as means ± SEM, = 4; < 0.01 versus duodenum; < 0.05 versus ileum; < 0.01 versus ileum. (c) A single-channel recording was performed in high-K⁺ solutions in the cell-attached mode at +100 mV. The lower diagram is an extension of the underlined part of the upper diagram. Seven open levels were recorded in the patch.
