Recently, baicalin refers to flavonoid compound extracted from Scutellaria baicalensis Georgi has been indicated to hold promising therapeutic effects in alcohol-associated liver disease (ALD). However, knowledge of the molecular mechanisms for its hepatoprotective effect is still very limited. Evidence exists suggesting potential association between miR-205 and baicalin's function. Bioinformatic analysis and dual luciferase reporter assay were conducted to determine the binding affinity between miR-205 and importin alpha 5. Our findings revealed that baicalin could alleviate ALD by raising the expression of miR-205. Additionally, miR-205 repressed NF -KB signaling pathway activation by binding to importin alpha 5 to relieve ALD. Baicalin inhibited importin alpha 5-mediated NF -KB signaling pathway to protect the liver against alcohol-induced injury, inflammation, oxidative stress and hepatocyte apoptosis. Taken conjointly, baicalin confers hepatoprotective effect against ALD through miR-205mediated importin alpha 5 inhibition via the NF -KB signaling pathway, highlighting a promising therapeutic target for ALD treatment with the help of traditional Chinese medicine.
