Figure 4. Effects of PE to stimulate NOi release in atrial myocytes.

Figure 4

A; PE (10 μm) is unable to stimulate NOi release in a quiescent atrial myocyte. Exposure to 300 μm spermine/NO (an NO donor) increases NOi. B; PE (10 μm) stimulates NOi release in an atrial myocyte field stimulated at 1 Hz. C; PE (1, 10, 100 μm) elicits a dose-dependent increase in NOi release. D; summary of dose-dependent PE-induced stimulation of NOi. The numbers in parentheses indicate the number of cells tested in each experiment.
