In the current study, we aimed to investigate the effect of carvacrol on the suppression of liver fibrosis progression through targeting lysyl oxidase (LOX) expression. The rats received carbon tetrachloride (CCl) intraperitoneally and carvacrol orally for 10 weeks. Liver damage was evaluated by measuring the serum level of alanine aminotransferase, aspartate aminotransferase and alkaline phosphatase and hepatic oxidative stress parameters including total antioxidant capacity, total thiol group and total oxidant status spectrophotometry and malondialdehyde fluorometrically. Extracellular deposition of collagen was detected using Masson's trichrome standing. Furthermore the gene expression of lysyl oxidase homolog 2 (Loxl2) was analyzed using quantitative reverse transcription-polymerase chain reaction. And then the protein level of LOX was detected in liver tissue by western blot method. Carvacrol administration normalized serum biochemical parameters and improved oxidative stress status in liver homogenate of CCl treated rats. Collagen fiber bundles in interlobular spaces were decreased remarkably by carvacrol treatment. Also, carvacrol downregulated hepatic gene expression of Loxl2 and protein level of LOX. Our data clearly revealed that carvacrol suppresses progression of liver fibrosis development via attenuating of liver damage and oxidative stress status as well as via downregulation of hepatic gene expression of Loxl2 and protein level of LOX.
