Potassium Current Is Not Affected by Long-Term Exposure to Ghrelin or GHRP-6 in Somatotropes GC Cells

Inactivation in steady state of the total voltage-dependent K+ current in the cellular line of rat GC somatotropes. (a) Family of representative traces of the steady-state inactivation for the total voltage-dependent K+ current. The current was evoked by a double-pulse protocol. The first pulse, named conditioning, starts from a membrane potential of −130 mV, having duration of 1.5 sec and varying amplitude; the second one, testing, carries a membrane potential of 70 mV with duration of 500 ms. (b) The current at the peak of the testing pulse was graphed according to the voltage of the conditioning pulse, this being normalized in regard to the maximum current.
