Background
It is well acknowledged that alcoholic liver disease (ALD) is widely prevalent all over the world, characterized by aberrant lipid deposition and excessive oxidative stress in hepatocytes. Recently, pyroptosis, a new type of programmed cell death, has been found in ALD, which provides new ideas for the treatment of ALD.
Conclusion
Our research revealed that oroxylin A could alleviate ALD via PGC-1α/Mfn2 signaling mediated canonical pyroptosis pathway resistance.
Methods
Male ICR mice were treated with the Lieber-De-Carli diet (Dyets) or isocaloric liquid diet for 8 weeks, and binge alcohol model was also used for ALD. Blood and livers were taken to evaluate the efficacy of oroxylin A. The levels of factors related to hepatocyte pyroptosis were measured via western blot analyses, immunofluorescence analyses and quantitative reverse transcriptase in vitro. Result: Our study found that oroxylin A suppressed hepatocyte pyroptosis through a NLRP3 inflammasome dependent-canonical caspase-1 pathway.
