Treatment with OCA prevents hCLS formation and liver fibrosis in “inducible NASH model”. (a) Experimental protocol for examination of the preventive effect of OCA on hCLS formation and liver fibrosis in the inducible NASH model. (b) Hepatic mRNA expression levels of genes related to p53-regulated genes (p21 and Ctgf) 2 days after CCl4 injection. (c) TUNEL staining of the liver 4 days after CCl4 injection. (d) Histological analysis of hCLS using F4/80 immunostaining of the liver 7 days after CCl4 injection. (e) Sirius red-positive area and representative Sirius red-stained liver sections 7 days after CCl4 injection. Scale bars, 100 μm. CV, central veins. (f) Hepatic mRNA expression levels of genes related to fibrogenic factors (Tgfb1 and Col1a1) 7 days after CCl4 injection. V, Vehicle. #p < 0.05, ##p < 0.01. Vehicle-treated WT-SD group with olive oil injection, n = 10; vehicle-treated MC4R-WD group with CCl4 injection, n = 10; OCA (10 mg/kg)-treated MC4R-WD group with CCl4 injection, n = 10.
