Abstract
Alcoholic liver disease (ALD) is caused by chronic excessive alcohol consumption, which leads to inflammation, oxidative stress, lipid accumulation, liver fibrosis/cirrhosis, and even liver cancer. However, there are currently no effective drugs for ALD. Herein, we report that a natural phytosterol Daucosterol (DAU) can effectively protect against liver injury caused by alcohol, which plays anti−inflammatory and antioxidative roles in many chronic inflammatory diseases. Our results demonstrate that DAU ameliorates liver inflammation induced by alcohol through p38/nuclear factor kappa B (NF−κB)/NOD−like receptor protein−3 (NLRP3) inflammasome pathway. Briefly, DAU decreases NF−κB nuclear translocation and inhibits NLRP3 activation by decreasing p38 phosphorylation. At the same time, DAU also protects against hepatic oxidative stress and lipid accumulation. In conclusion, our research provides a new clue about the protective effects of naturally active substances on ALD.
