Upregulation of Voltage-Gated Calcium Channel Cav1.3 in Bovine Somatotropes Treated with Ghrelin
Figure 6
Calcium channel activity in bovine somatotropes. (a) Family of current traces obtained from a control and treated cell with Ghrelin (10 nM) for 48 h; the holding potential is fixed to −80mv, and after that a prepulse was clamped at −40 mv with a duration of 50 ms was applied to inactivate the low voltage-gated calcium channels. (b) Average current-voltage () relationships obtained from control (, ) and treated cells (, ) measured at the end of the command pulse.
