Inhibition of ATP-regulated K+ channels precedes depolarization-induced increase in cytoplasmic free Ca2+ concentration in pancreatic beta-cells.

The effects of glucose, diazoxide, K+, and tolbutamide on the activity of K+ channels, membrane potential, and cytoplasmic free Ca2+ concentration were investigated in beta-cells from the Uppsala colony of obese hyperglycemic mice. With [K+]e = [K+]i = 146 mM, it was demonstrated that the dominating...
