Abstract

Dysregulated bile acids (BAs) are closely associated with liver diseases and attributed to altered gut microbiota. Here, we show that the intrahepatic retention of hydrophobic BAs including deoxycholate (DCA), taurocholate (TCA), taurochenodeoxycholate (TCDCA), and taurolithocholate (TLCA) were substantially increased in a streptozotocin and high fat diet (HFD) induced nonalcoholic steatohepatitis‐hepatocellular carcinoma (NASH‐HCC) mouse model. Additionally chronic HFD‐fed mice spontaneously developed liver tumors with significantly increased hepatic BA levels. Enhancing intestinal excretion of hydrophobic BAs in the NASH‐HCC model mice by a 2% cholestyramine feeding significantly prevented HCC development. The gut microbiota alterations were closely correlated with altered BA levels in liver and feces. HFD‐induced inflammation inhibited key BA transporters, resulting in sustained increases in intrahepatic BA concentrations. Our study also showed a significantly increased cell proliferation in BA treated normal human hepatic cell lines and a down‐regulated expression of tumor suppressor gene CEBPα in TCDCA treated HepG2 cell line, suggesting that several hydrophobic BAs may collaboratively promote liver carcinogenesis.

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

  • Progression of chronic liver injury is associated with a relationship between dysbiosis and specific bile acid formation (DCA, LCA, TCDCA, GCDCA), with increases in Clostridium, Bacteroides, and E. coli and reduction in A. muciniphila that significantly correlated with specific increases in secondary bile acids.

    “The progression of chronic liver injury was associated with a relationship between dysbiosis and specific BA formation (DCA, LCA, TCDCA, GCDCA) with an increase in specific bacteria genera (Clostridium, Bacteroides, E. Coli) and reduction in A. muciniphila that significantly correlated with specific increases in secondary BA [248,249].”

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.
