Key result
A single intravenous injection of beta1-AS-ODN in spontaneously hypertensive rats decreased cardiac beta1-AR density by 30-50% (P<0.01) and reduced blood pressure for 20 days.

Does a single intravenous injection of beta1-AS-ODN reduce blood pressure and cardiac beta1-AR density in spontaneously hypertensive rats?
p-value: p=<0.01
A single dose of beta1-AS-ODN provides profound and prolonged blood pressure reduction in hypertensive rats without causing bradycardia or CNS effects, suggesting a potential novel approach to specific beta1-blockade.
Zhang et al. (2000) studied Hypertension. beta1-AS-ODN vs. Atenolol was evaluated on Cardiac beta1-AR density and blood pressure (p=<0.01). A single intravenous injection of beta1-AS-ODN in spontaneously hypertensive rats decreased cardiac beta1-AR density by 30-50% (P<0.01) and reduced blood pressure for 20 days.
