Extracellular ATP increases cytoplasmic free Ca2+ concentration in clonal insulin-producing RINm5F cells. A mechanism involving direct interaction with both release and refilling of the inositol 1,4,5-trisphosphate-sensitive Ca2+ pool.
Effects of extracellularly applied ATP (added as disodium salt) on stimulus-secretion coupling were investigated in clonal insulin-producing RINm5F cells. Cytoplasmic free Ca2+ concentration [( Ca2+]i), electrical activity, membrane potential, formation of InsP3 and insulin release were measured. Ad...
