Adenosine is important in the regulation of vascular tone and the Equilibrative Nucleoside Transporter 1 (ENT1) is a regulator of adenosine concentrations. Thus, changes in ENT1 expression and activity may alter vascular tone regulation. We therefore examined the cardiovascular phenotype of ENT1-null (ENT1-/-) as compared to wild type mice (ENT1+/+). Heart rates (HRs) and blood pressures (BPs) of ENT1-/- and ENT1+/+ littermate male mice were obtained while conscious and anaesthetized, and metabolic data were collected over a 24 hr period. Vascular reactivity was assessed in aortic ring segments obtained from 3 month old ENT1 …
