Aims
Excessive alcohol consumption can lead to alcoholic liver diseases (ALDs). Tetrastigma hemsleyanum Diels et Gilg is a rare Chinese medicinal herb. Tetrastigma hemsleyanum Diels et Gilg has been validated to be highly effective for treating hepatitis. Kaempferol and nicotiflorin are two highly representative flavonoids, which have exhibit therapeutic effects on liver disease. Therefore, the protective mechanism of kaempferol and nicotiflorin on alcohol-induced liver injury were investigated. Main
Methods
Forty mice were used in this study. After treatment of Kaempferol and nicotiflorin, serum and liver were collected and used for determination of biochemical indicators, H&E staining, and molecular detection. The interaction of miRNAs from serum extracellular vehicles (EVs) with mRNAs and 16S rRNA sequencing of gut microbiota were also investigated. Key findings: The
Significance
Kaempferol and nicotiflorin reduced alcohol-induced liver damage by enhancing alcohol metabolism and reducing oxidative stress and lipid metabolism. The intestinal microorganism disorder was also ameliorated after oral kaempferol and nicotiflorin.
