Increased Angiotensin II Contraction of the Uterine Artery at Early Gestation in a Transgenic Model of Hypertensive Pregnancy Is Reduced by Inhibition of Endocannabinoid Hydrolysis

Increased vascular sensitivity to angiotensin II (Ang II) is a marker of a hypertensive human pregnancy. Recent evidence of interactions between the renin-angiotensin system and the endocannabinoid system suggests that anandamide and 2-arachidonoylglycerol may modulate Ang II contraction. We hypothesized that these interactions may contribute to the enhanced vascular responses in hypertensive pregnancy. We studied Ang II contraction in isolated...
