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

Figure 4

Effect of secretagogues (ghrelin and GHRP-6) on the K+ current. (a), (b), and (c): family of representative traces of the K+ current on GC cells in control conditions, treated with ghrelin (10 nM), or GHRP-6 (100 nM), for 96 hours. (d) Current-voltage relationship for each one of the experimental conditions (control; , ghrelina 10 nM; , and GHRP-6 100 nM; ); the measurements were taken at the peak (the first 50 ms), the sustained component (the last 5 ms; 1.455–1.5 s), and the subtraction of peak minus sustained component.
