Fast voltage-dependent sodium (Na
Corpus cavernosum smooth muscle (CCSM) exhibits phasic contractions that are coordinated by ion channels. Mouse models are commonly used to study erectile dysfunction, but there are few published electrophysiological studies of mouse CCSM. We describe the voltage-dependent sodium (Na. Fast, voltage-dependent, sodium currents in mouse CCSM were induced by depolarising steps. Steady-state activation and inactivation curves revealed a window current between -60 and -30 mV. Two populations of Na. There are fast, voltage-dependent, sodium currents in mouse CCSM. Stimulation of these currents increased contractility of CCSM in vitro, suggesting an involvement in detumescence and potentially providing a clinically relevant target in erectile dysfunction. Further work will be necessary to define its role.
