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

Figure 1

Voltage-dependent potassium current in the cellular line of rat GC somatotrope. (a) Family of representative traces of voltage-dependent K+ current in GC cells, evoked by depolarizing voltage pulses with increases of 10 mV, starting from a holding potential in the prepulse of −130 mV with duration of 500 ms, followed by a voltage pulse lasting for 1.5 sec. The initial maintenance potential was fixed at −80 mV. In the lower part, the acquisition protocol is shown. (b) Current-voltage relationship for the transient component ( ; the first 50 ms), the sustained component ( ; 1.455–1.50 s), and the subtraction .
