Figure 2.
Maximal responses in mean arterial blood pressure (MAP) to acute bolus application of INS45973 (P2Y2/4 agonist) in endothelial NO synthase knockout mice (eNOS−/−, n = 5). In eNOS−/− mice, application of INS45973 induced a dose-dependent, rapid decrease in blood pressure (left side, early phase). The dose-dependent rise in blood pressure above basal values following the initial decrease in eNOS−/− mice was significantly impaired compared to WT mice (right side, late phase). Some error bars are covered. *P < 0.05 vs. WT (two-way anova with repeated measures followed by Dunnett’s test).
