  • Changes in intracellular free Ca2+, [Ca2+]i, and immunoreactive insulin release in response to alpha-adrenergic agents were measured in RINm5F cell suspensions. Cells were loaded with the fluorescent indicator quin 2 for monitoring [Ca2+]i. Epinephrine (1 microM), which inhibited alanine-stimulated insulin release by 73%, evoked a transient rise in [Ca2+]i. This rise is in part due to Ca2+ mobilization, since it is still present in the absence of extracellular Ca2+. The alpha 2-adrenergic… CONTINUE READING
