(a) SBP measurements in SHRSP injected daily with vehicle or the TGR5
agonist OA. (b) Acetylcholine (Ach_induced vasodilation of mesenteric arteries
isolated from vehicle- or OA-treated SHRSPs. (c) Calculated EC50
values for acetylcholine induced vasodilation of mesenteric arteries isolated
from vehicle or OA treated SHRSPs. Data presented as mean ± SEM. (a)
Two-way ANOVA main effects of age (p<0.0001), treatment (p=0.0317), and
age x treatment (p=0.0023). (b) Two-way ANOVA main effects of Ach dose
p<0.0001, treatment p=0.0262, dose x treatment p=0.0125. (c) unpaired
t-test. *p≤0.05 vs SHRSP vehicle, **p≤0.01 vs SHRSP vehicle,
n=5-6
