Why the study?
Endothelial cyclooxygenase-1-derived prostanoids have cardioprotective roles but also suggested paradoxical pathological arterial activities, yet testing this was previously impossible without models separating vascular products from those generated elsewhere.
Population
Endothelial-specific cyclooxygenase-1 knockout mice
Design
Preclinical animal study

Endothelial COX-1 knockout model isolates vascular prostanoid effects; leaves open clinical relevance in human arteries.
Endothelial cyclooxygenase-1 paradoxically drives local vasoconstriction and atherogenesis, highlighting its potential as a therapeutic target.
Mitchell et al. (2021) studied this question.
