Figure 9. Stim1-smKO mice are hypotensive.
(A) Systolic blood pressure (BP) (mmHg) over 48 hr in conscious, radio telemeter-implanted Myh11CreERT2: Stim1fl/fl mice before (control) and after (Stim1-smKO) tamoxifen injection. Shaded regions depict night cycles (n = 5 for both groups; *p<0.05 vs. control day, #p<0.05 vs. control night, paired t-test). (B) Diastolic BP measurements for control and Stim1-smKO mice (n = 5 for both groups, paired t-test). ns, not significant. (C) Mean arterial pressure (MAP) for control and Stim1-smKO mice (n = 5 for both groups, #p<0.05 vs. control night, paired t-test). ns, not significant. (D) Pulse pressure for control and Stim1-smKO mice (n = 5 for both groups; *p<0.05 vs. control day, #p<0.05 vs. control night, paired t-test). (E) Heart rate (HR) for control and Stim1-smKO mice (n = 5 for both groups, paired t-test). ns, not significant. (F) Locomotor activity (arbitrary units [AU]) for control and Stim1-smKO mice (n = 5 for both groups, paired t-test). ns, not significant. 48 hr recordings are shown as means; bar graphs are shown as means ± SEM.
