Abstract

Mineralocorticoid receptor antagonists (MRAs) reduce morbidity and mortality in chronic heart failure. Novel nonsteroidal MRAs are currently developed and need to be pharmacologically characterized in comparison to classical steroidal MRAs. A mouse model of cardiac fibrosis induced by short-term isoproterenol injection was used to compare the nonsteroidal MRA finerenone and the steroidal MRA eplerenone in equi-efficient systemic MR blocking dosages. Molecular mechanisms were studied in MR-expressing H9C2/MR+ cardiomyocytes and in MR transcriptional cofactor binding assays. Both MRAs significantly inhibited an isoproterenol-mediated increase of left ventricular mass. Isoproterenol-induced cardiac fibrosis and macrophage invasion were potently blocked by finerenone, whereas eplerenone had no significant effect. Speckle tracking echocardiography revealed a significant improvement of global longitudinal peak strain by finerenone, an effect less prominent with eplerenone. Antifibrotic actions of finerenone were accompanied by a significant inhibition of profibrotic cardiac TNX ( tenascin-X ) expression, a regulation absent with eplerenone. Finally, we show a higher potency/efficacy and inverse agonism of finerenone versus eplerenone in MR transcriptional cofactor binding assays indicating differential MR cofactor modulation by steroidal and nonsteroidal MRAs. This study demonstrates that the nonsteroidal MRA finerenone potently prevents cardiac fibrosis and improves strain parameters in mice. Cardiac antifibrotic actions of finerenone may result from the inhibition of profibrotic TNX gene expression mediated by differential MR cofactor binding. Selective MR cofactor modulation provides a molecular basis for distinct (pre)-clinical actions of nonsteroidal and steroidal MRAs.

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.
