Abstract

Background: Therapeutic options to treat N on‐alcoholic steatohepatitis (NASH) are limited. Mineralocorticoid receptor (MR) activation could play a role in hepatic fibrogenesis and its modulation could be beneficial for NASH. Aim: To investigate whether eplerenone, a specific MR antagonist, ameliorates liver damage in experimental NASH. Methods: C57bl6 mice were fed a choline‐deficient and amino acid‐defined (CDAA) diet for 22 weeks with or without eplerenone supplementation. Serum levels of aminotransferases and aldosterone were measured and hepatic steatosis, inflammation and fibrosis scored histologically. Hepatic triglyceride content (HTC) and hepatic mRNA levels of pro‐inflammatory pro‐fibrotic, oxidative stress‐associated genes and of MR were also assessed. Results: CDAA diet effectively induced fibrotic NASH, and increased the hepatic expression of pro‐inflammatory, pro‐fibrotic and oxidative stress‐associated genes. Hepatic MR mRNA levels significantly correlated with the expression of pro‐inflammatory and pro‐fibrotic genes and were significantly increased in hepatic stellate cells obtained from CDAA‐fed animals. Eplerenone administration was associated to a reduction in histological steatosis and attenuation of liver fibrosis development, which was associated to a significant decrease in the expression of collagen‐α1, collagen type III, alpha 1 and M atrix metalloproteinase‐2. Conclusion: The expression of MR correlates with inflammation and fibrosis development in experimental NASH. Specific MR blockade with eplerenone has hepatic anti‐steatotic and anti‐fibrotic effects. These data identify eplerenone as a potential novel therapy for NASH. Considering its safety and FDA‐approved status, human studies are warranted.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Several genes were previously connected with fatty liver disease such as Nr3c1, Nr3c2, Zbtb16, Dnmt1, and Keap1, but most of the top genes had no connections with liver disease or NASH.

    “Several genes were previously connected with fatty liver disease such as the glucocorticoid receptor Nr3c128,29, the mineralocorticoid receptor Nr3c230,31, the transcription factor Zbtb1632, the DNA methyltransferase Dnmt133, and the E3 ubiquitin ligase adaptor Keap134,35, but most of the top genes had no connections with liver disease or NASH.”

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.
