Electrophysiological properties of two potassium channels in mitoplasts isolated from glioblastoma and keratinocyte cell line. A Scheme of the patch-clamp experiments performed with calcitriol. B Effect of changed calcium ion concentration and paxilline on the activity of the mitoBKCa channel. (o1) (o2) indicates an open state of channels 1 and 2 respectively. (c) indicates a closed state. C Effect of changed calcium concentration and lidocaine on the activity of the TASK-3 channel. (o) indicates an open state of the channel. (c) indicates a closed state. D, E Resistance of the patch during the external perfusion with calcitriol on mitoplasts from glioblastoma and keratinocyte cells respectively
