  • Activation of the sympathetic nervous system inhibits insulin secretion. We tested the hypothesis that activation of alpha 2-adrenergic receptors on the beta-cell by epinephrine or clonidine attenuates insulin release by an effect on the voltage-dependent Ca2+ channel (VDCC) and examined the role of G-proteins in this signal transduction pathway. Using a cultured SV40-transformed hamster beta-cell line (HIT cells) as a model system, we determined the effect of alpha 2-adrenergic agonists on… CONTINUE READING
