TRPM8 deficiency alleviates BDL-induced liver fibrosis in mice. A Representative images of H&E, Sirius Red, Masson’s trichrome, and IHC staining for α-SMA and COL1A1 in the liver of WT and TRPM8^−/− mice operated with BDL (n = 5 per group). Positive staining areas were quantified by Image J software. Scale bars, 100 μm. B Liver function was assessed by measuring the serum levels of ALT and AST in mice (n = 5 per group). C Immunoblotting analyses of α-SMA and COL1A1 expression in the mouse liver (n = 3 per group). D Hepatic mRNA levels of fibrogenic genes were measured by qRT-PCR (n = 5 per group). The results are expressed as the mean ± SD. *P < 0.05, **P < 0.01, ***P < 0.001, ****P < 0.0001
