Figure 6. Relaxation responses to the nitroxyl anion donor, Angeli’s Salt, are mediated through soluble guanylate cyclase.
Concentration response curves to AS were performed in Phe (1 µM) contracted aorta from AngII (AngII) and sham (Sham) in the presence of the (a) voltage-gated potassium channel blocker, 4-AP (100 mM) and the (b) soluble guanylate cyclase inhibitor, ODQ (1 µM). Data are represented as mean ± SEM; n=5–8. ‡p<0.0001, EC50 values of 4-AP vs. vehicle in AngII, ‡p<0.0001, Rmax values of ODQ vs. vehicle in sham and AngII.
