Abstract

Objective: Cardiac natriuretic peptides (NPs) bind to two receptors (NPRA‐mediator of signaling; NPRC‐clearance receptor) whose ratio, NPRR (NPRA/NPRC), determines the NP bioactivity. This study investigated the relationship of NP receptor gene expression in adipose tissue and muscle with obesity and glucose intolerance. Prospectively, the study also assessed whether changes in NP receptor expression and thermogenic gene markers accompanied improvements of insulin sensitivity. Methods: A cross‐sectional study of subjects with a wide range of BMI and glucose tolerance ( n = 50) was conducted, as well as a randomized 12‐week trial of subjects with type 2 diabetes mellitus (T2DM) treated with pioglitazone ( n = 9) or placebo ( n = 10). Results: NPRR mRNA was significantly lower in adipose tissue of subjects with obesity when compared with lean subjects ( P ≤ 0.001). NPRR decreased with progression from normal glucose tolerance to T2DM ( P < 0.01) independently of obesity. Treatment of subjects with T2DM with pioglitazone increased NPRR in adipose tissue ( P ≤ 0.01) in conjunction with improvements in insulin sensitivity and increases of the thermogenic markers PPARγ coactivator‐1α and uncoupling protein 1 ( P ≤ 0.01). Conclusions: Decreased adipose tissue NPRR was associated with obesity, glucose intolerance, and insulin resistance. This relationship was not observed for skeletal muscle NPRR. Pharmacological improvement of insulin sensitivity in subjects with T2DM was tied to improvement in NPRR and increased expression of genes involved in thermogenic processes.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
