Abstract

BACKGROUND: FSTL1 (follistatin-like protein 1) is an emerging cardiokine/myokine that is upregulated in heart failure (HF) and is found to be cardioprotective in animal models of cardiac injury. We tested the hypothesis that circulating FSTL1 can affect cardiac function and metabolism under baseline physiological conditions and in HF. METHODS AND RESULTS: C-glucose were infused to track the metabolic fate of free fatty acids and glucose. Cardiac uptake of lactate and ketone bodies and systemic respiratory quotient were also measured. HF caused a shift from prevalent cardiac and systemic fat to carbohydrate oxidation. Although acute FSTL1 administration caused minimal hemodynamic changes at baseline, in HF dogs it enhanced cardiac oxygen consumption and transiently reversed the changes in free fatty acid and glucose oxidation and systemic respiratory quotient. In HF, chronic FSTL1 infusion stably normalized cardiac free fatty acid, glucose, ketone body consumption, and systemic respiratory quotient, while moderately improving diastolic and contractile function. Consistently, FSTL1 prevented the downregulation of medium-chain acyl-CoA dehydrogenase-a representative enzyme of the free fatty acid oxidation pathway. Complementary in vitro experiments in primary cardiac and skeletal muscle myocytes showed that FSTL1 stimulated oxygen consumption through AMPK (AMP-activated kinase) activation. CONCLUSIONS: These findings support a novel function for FSTL1 and provide the first direct evidence that a circulating cardiokine/myokine can alter myocardial and systemic energy substrate metabolism, in vivo.

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.
