Metabolism of Natriuretic peptides and impact on insulin resistance and fat mass in healthy subjects

We find no evidence that increased clearance/degradation of NPs contributes to insulin resistance. Among the nine NP variants assessed, only NT-proANP and NT-proBNP independently predicted insulin resistance in both sexes. The impact of CNP on fat mass or insulin resistance was minor but significant in females. Lower concentrations of immunoreactive plasma ANP and BNP remains unexplained and requires closer study.
