INTRODUCTION: Alcoholic liver disease (ALD), induced by chronic and excessive alcohol consumption, poses a significant health risk, with higher female susceptibility. This study investigated Lactobacillus plantarum fermented persimmon juice (Fj) against ALD in female C57BL/6 mice.
METHODS: The model mice were orally treated with Fj or unfermented persimmon juice (Pj). The bioactive compound profiles of Fj and Pj were detected by HPLC-MS. The hepatoprotective effects was evaluated through assessments of hepatic lipid metabolism, Keap1/Nrf2 pathway proteins, and ferroptosis markers.
RESULTS: HPLC-MS analysis confirmed Fj was enriched in bioactive compounds including elevated antioxidants such as chlorogenic acid and p-hydrobenzoic acid. Daily Fj administration (10 μg/g BW) significantly improved hepatic lipid metabolism and regulated Keap1/Nrf2 signaling pathway, ultimately mitigating hepatic ferroptosis.
CONCLUSION: These findings demonstrate that probiotic fermentation as a strategic approach to develop postbiotic-based functional beverages for mitigating alcohol-induced liver injury, offering translational potential against ALD progression.
