Key result
Selective deletion of GC-A in vascular smooth muscle abolished the acute hypotensive effects of ANP infusion but did not affect chronic resting arterial blood pressure.
Why the study?
Does smooth muscle-selective deletion of guanylyl cyclase-A affect the acute and chronic hypotensive actions of ANP in mice?
Population
Mice with smooth muscle-selective deletion of guanylyl cyclase-A and floxed GC-A control mice
Comparison
Infusion of ANP and acute vascular volume… vs Floxed GC-A control mice

Vascular GC-A mediates acute ANP hypotension in mice; leaves open chronic BP mechanisms and human relevance.
Does smooth muscle-selective deletion of guanylyl cyclase-A affect the acute and chronic hypotensive actions of ANP in mice?
Vascular GC-A is critical for the acute moderation of arterial blood pressure by ANP but dispensable for chronic blood pressure regulation.
Holtwick et al. (2002) studied Blood pressure regulation. Selective deletion of GC-A in vascular smooth muscle vs. Floxed GC-A mice was evaluated on Arterial blood pressure response to ANP infusion and acute vascular volume expansion. Selective deletion of GC-A in vascular smooth muscle abolished the acute hypotensive effects of ANP infusion but did not affect chronic resting arterial blood pressure.
