Abstract:
BK-Kanäle spielen eine wichtige Rolle in der NO-vermittelten Relaxation glatter Muskelzellen in Widerstandgefäßen (Brayden and Nelson 1992). Unklar war bisher, wie es dem NO gelingt, den BK-Kanal zu aktivieren. Wirkt das NO durch direkte Aktivierung des BK-Kanals (Bolotina, Najibi et al. 1994) oder ist für die Wirkung des NO immer ein second-messenger, wie z.B. das cGMP/cGKI-System erforderlich (Alioua, Huggins et al. 1995; Fukao, Mason et al. 1999; Tomioka, Hattori et al. 1999)?

Translated abstract:
BK channels play an essential role in NO-mediated relaxation of vascular smooth muscle cells. The molecular mechnisms involved in NO-mediated regulation of BK channels presently are not clear. Is the activity of these channels regulated directly by NO or is there always a second-messenger involved, like the cGMP/cGKI-system? In this study th BK channel of vascular smooth muscle cells of mice was characterised. Then the regulation of BK channels by NO was analysed in cGKI-/- smooth muscle c...     »
