The expression of TGR-5 is increased in chronic liver diseases.
The expression of TGR-5 was significantly higher in diseased livers than in NL and the pattern of expression was different within diseases, with PSC liver expressing a moderate level of TGR-5 when compared to other diseases (PBC, ALD and NASH); (A) Representative images for TGR-5 immunohistochemistry staining from different diseased livers and normal control (TGR-5, brown); (B) The pattern of TGR-5 expression in liver tissue from different sources; (C) Tissue taken from patients with PSC expressed lower levels of TGR-5 compared to other diseased livers. Expression was estimated as percent surface area using ImageJ. Data are represented as median ± IQR. One-Way ANOVA with multiple comparison was used for statistical analysis. ****p ≪0.001; ***p ≪0.005; *p ≪0.05.
ALD, alcohol-related liver disease; NASH, non-alcoholic steatohepatitis; NL, normal liver; PBC, primary biliary cholangitis, PSC, primary sclerosing cholangitis.
