Introduction: To explore the role of ADAMTS-1 in alcoholic liver fibrosis in mice, and to provide theoretical targets in clinical research and treatment of alcoholic liver fibrosis. 

Materials and methods: CRISPR/Cas9 technology was used to inhibit the expression of ADAMTS-1 gene in the mice which were fed with a Lieber-DeCarli diet that contained 5% alcohol by mass for 8 weeks. Then, the effect of ADAMTS-1 on liver fibrosis was explored through histopathology and western blotting. 

Results: Inhibiting the expression of ADAMTS-1 promotes the progress of alcoholic liver fibrosis in mice. 

Conclusion: Inhibition of ADAMTS-1 aggravated the process of alcoholic liver fibrosis by promoting the overexpression of various pro-injury factors and the activation of TGF-b/Smad3 signaling pathway. Which means that ADAMTS-1 has a protective effect on alcoholic liver fibrosis in mice.
