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

Figure 8

Activation curves of the voltage-dependent potassium current in the cellular line of rat GC somatotropes. (a) Activation curves of the current for control conditions and treated with GHRP-6 100 nM for 96 h. The conductances were obtained and these were normalized in regard to the maximum value. The continuous lines represent the adjustment of data with a Boltzmann-type equation. (b) Maximum conductance value for each one of the experimental conditions; the numbers beside the error bar represent the number of cells analyzed. (c) and (d): Boltzmann-type adjustment values, midpoint and slope factor ( ), respectively. The adjustments were obtained from the cell-current data shown in Figure 7.
