Key result

Atrial natriuretic peptide treatment increased skeletal muscle albumin clearance, accounting for at most 30% of the whole body clearance required to regulate plasma volume.

Population

C57BL6 mice; mice with endothelium-restricted deletion of GC-A (floxed GC-A x tie2-Cre: endothelial cell…

Comparison

Overview

No immediate change to volume management; extends mechanistic insight into ANP endothelial actions but leaves clinical translation open.

Structured PICO

P
Population
Mice models including C57BL6, endothelial cell GC-A knockout, and control littermates used to evaluate ANP-induced microvascular permeability.
I
Intervention
Atrial natriuretic peptide (ANP) treatment
C
Comparator
Normovolaemic littermates or baseline
O
Outcome
Blood-to-tissue albumin transport (plasma albumin clearance) and microvascular permeability to 35 kD Gadomer contrast agentsurrogate

ANP induces small increases in microvascular permeability in skeletal muscle and skin, accounting for a minor portion of the whole-body clearance required for plasma volume regulation.

Cite This Study

Curry et al. (2009) studied this question. Atrial natriuretic peptide (ANP) vs. Control littermates / baseline was evaluated on Albumin clearance and microvascular permeability. Atrial natriuretic peptide treatment increased skeletal muscle albumin clearance, accounting for at most 30% of the whole body clearance required to regulate plasma volume.
