The effect of ionomycin, forskolin, ethanol and CDCA on ATP release. The time courses of the ATP release from Capan-1 after stimulation of the cells with (a) ionomycin (5 μM, n = 6) and (b) forskolin (50 μM, n = 6), (c) bile acid chenodeoxycholic acid (CDCA, 0.25 mM, n = 5) and (d) ethanol (10 and 100 mM, n = 4). The left axis shows the ATP concentration values corrected per 106 cells in 1 ml. The arrow indicates the time of adding the stimulants
