Dopamine reduces voltage-dependent calcium channel currents. (A) Representative Ca2+ current traces recorded from different rat β-cells treated with dopamine (DA, 10 μM) in the presence or absence of eticlopride (Eti, 10 μM). (B) Current-voltage relationship curves obtained from the treated cells. (C) Summary of the mean current density of Ca2+ currents at 0 mV depolarization. Data are expressed as the mean ± SEM and compared by one-way ANOVA. Pancreatic β-cells were confirmed based on their capacitance values >7 pF (n = 6 β-cells/group), **P < 0.01; ***P < 0.001.
