ETHNOPHARMACOLOGICAL RELEVANCE: Acute-on-chronic liver failure (ACLF) represents a severe clinical syndrome characterized by rapid exacerbation of chronic hepatic disease. Liver fibrosis (LF) significantly contributes to the advancement of ACLF pathology. The traditional Chinese medicine (TCM) preparation Yi-Qi-Jian-Pi formula (YQJPF) exhibits promising therapeutic effects on ACLF and LF; however, the underlying pharmacological mechanisms and active components remain incompletely understood.
AIM OF THE STUDY: This study seeks to elucidate the pharmacodynamic properties, active constituents, and underlying mechanisms of YQJPF in treating liver fibrosis within an ACLF rat model, focusing specifically on ferritinophagy activation and the induction of hepatic stellate cell (HSC) senescence.
MATERIALS AND METHODS: A rat model of ACLF was induced via combined administration of CCl4 and LPS/D-GalN, and an in vitro model was established using human hepatic stellate cells (LX2). Liver-targeted active components were characterized using UHPLC-Q-Orbitrap-MS/MS analysis, with network pharmacology utilized to predict critical molecular targets. NCOA4 siRNA and ferrostatin-1 were used to validate mechanism specificity. The therapeutic effects and associated mechanisms were systematically evaluated through biochemical assays, histopathological examinations, and molecular and cellular analyses.
RESULTS: YQJPF improved liver histopathology and attenuated fibrosis and ACLF in rats. It inhibited viability and proliferation of LX2 cells, decreased TGF-β1 secretion, and downregulated α-SMA and Collagen I expression. UHPLC-Q-Orbitrap-MS/MS identified 82 liver-tropic components (including 50 prototypes and 32 metabolites) in rat liver tissues. Network pharmacology revealed 257 potential targets, with 135 overlapping with hepatic fibrosis-related targets (core targets included TP53, NCOA4, and CDKN2A). YQJPF induced HSC senescence (upregulated p16, p21, and HMGA1; downregulated TERT; triggered cell cycle arrest) and activated ferritinophagy (upregulated NCOA4, Beclin1, LC3BII/I; downregulated FTH1 and p62; increased ROS/iron accumulation). NCOA4 knockdown or Fer-1 treatment reduced YQJPF-induced HSC senescence and antifibrotic effects.
CONCLUSION: YQJPF reduces ACLF-related LF by NCOA4-mediated ferritinophagy, which promotes HSC senescence. The 82 liver-tropic components and 135 overlapping targets highlight its multi-component, multi-target effects, providing a scientific foundation for its clinical application.
