Abstract

Background and aims The farnesoid X receptor (FXR) is an endogenous sensor for bile acids and inhibits bile acid synthesis by inducing small heterodimer partner (SHP) gene expression. The aim of this study was to investigate whether FXR is expressed by and modulates function of hepatic stellate cells (HSCs).Methods The antifibrotic activity of FXR ligand was tested in 2 rodent models: the porcine serum and bile duct ligation (BDL).Results Twelve-week administration of 1-10 mg/kg 6-ethyl chenodeoxycholic acid (6-ECDCA), a synthetic FXR ligand, to porcine serum-treated rats prevented liver fibrosis development and reduced liver expression of alpha1(I) collagen, TGF-beta1 and alpha-SMA mRNA by approximately 90%. Therapeutic administration of 6-ECDCA, 3 mg/kg, to BDL rats reduced liver fibrosis and alpha1(I) collagen, transforming growth factor (TGF)-beta1, alpha-SMA, and tissue metalloproteinase inhibitor (TIMP)-1 and 2 messenger RNA (mRNA) by 70%-80%. No protection was observed in BDL rats treated with CDCA, 3 mg/kg, and ursodeoxycholic acid, 15 mg/kg. FXR expression was detected in HSCs. Exposure of HSCs to FXR ligands caused a 3-fold increase of SHP, reduced alpha1(I)collagen and TGF-beta1 by approximately 60%-70% and abrogates alpha1(I) collagen mRNA up-regulation induced by thrombin and TGF-beta1. By retrovirus infection and small interference RNA, we generated SHP overexpressing and SHP-deficient HSC-T6. Using these cell lines, we demonstrated that SHP binds JunD and inhibits DNA binding of adaptor protein (AP)-1 induced by thrombin.Conclusions By demonstrating that an FXR-SHP regulatory cascade promotes resolution of liver fibrosis, this study establish that FXR ligands might represent a novel therapeutic option to treat liver fibrosis.

  • Upregulation of SHP might lead to the major anti-fibrotic activity of FXR.

    “Fiorucci et al. investigated the role of SHP in HSC inhibition, concluding that upregulation of SHP might lead to the major anti-fibrotic activity of FXR.[61,62]”

  • The direct impact of FXR activation on liver fibrosis is still controversially discussed because there is partially conflicting data on FXR mRNA and protein expression in hepatic stellate cells and myofibroblasts.

    “Nevertheless, the direct impact of FXR activation on liver fibrosis is still controversially discussed as there is partially conflicting data on FXR mRNA and protein expression in HSC and myofibrobasts.[57,61]”

  • Hepatic stellate cells exposed to an FXR ligand show reduced expression of col1α1 and TGF-β and upregulation of the nuclear receptor NR0B2/SHP.

    “In vitro experiments demonstrated that HSCs exposed to an FXR ligand show a reduced expression of alpha-1 type 1 collagen (col1α1) and TGF-β and an upregulation of the nuclear receptor NR0B2 -the small heterodimer partner (SHP).[61]”

  • Activation of the FXR-SHP cascade by FXR agonism seemed to protect against liver fibrosis in another bile duct ligation model.

  • Fiorucci et al. found FXR gene and protein expression in rat hepatic stellate cells and in the passaged cell line HSC-T6, while Fickert et al. reported only marginal expression levels of FXR in human hepatic stellate cells and undetectable FXR protein expression in mouse hepatic stellate cells.

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.
