Figure 6

Mechanical stimulation induces release of ATP into the lumen of the stomach. The plot shows the mean release of ATP in nmol L−1 per sample in response to mechanical stimulation with an ascending series of distension stimuli from 10 to 40 cmH2O. Increases in pressure resulted in increased release of ATP in both wildtype controls (WT; circles; n = 8) and P2X3−/− animals (open circles; n = 6). Pressure significantly affected ATP release (F = 5.51; P < 0.01). There was no significant difference between WT and P2X3−/− mice (F = 0.39; P = 0.53).
