Time course (a) systolic blood pressure, (b) diastolic blood pressure, (c) mean arterial pressure (MAP) and (d) heart rate (HR) following MG132 (proteasome inhibitor) and BQ610 (selective ETA receptor antagonist) administration to normotensive (control) and hypertensive (DOCA-Salt) animals as detailed in Materials and Methods. (e) Representative traces of blood pressure and HR in normotensive and hypertensive rats following proteasome inhibition and ETA blockade.
