Abstract
BACKGROUND

Acute-on-chronic liver failure (ACLF) is a life-threatening condition characterized by acute hepatic decompensation and high short-term mortality. Although Wenyang Jiedu Huayu Formula (WYJD) has demonstrated therapeutic efficacy for alleviating liver injury and modulating immune inflammation, whether its hepatoprotective effects involve targeting succinate metabolism remains unclear.

AIM

To investigate whether WYJD exerts therapeutic effects in ACLF by targeting succinate metabolism and to elucidate the underlying molecular mechanisms.

METHODS

ACLF rat model was prepared by sensitization using bovine serum albumin, followed by D-galactosamine/lipopolysaccharide challenge. Animals were assigned to normal control, Model, WYJD, and WYJD plus succinate dehydrogenase (SDH) inhibitor groups. Therapeutic efficacy was evaluated using hepatic histopathology and inflammatory cytokine profiling. Succinate metabolism-related molecular changes were systematically analyzed using targeted energy metabolomics, biochemical enzyme activity assays, western blotting, and reverse transcription quantitative polymerase chain reaction. Mitochondrial ultrastructure was examined using transmission electron microscopy. Intrahepatic macrophage infiltration was assessed using immunofluorescence staining.

RESULTS

WYJD treatment markedly attenuated hepatic necrosis and inflammatory cell infiltration in ACLF rat models. Metabolomic analysis revealed succinate accumulation and tricarboxylic acid cycle dysfunction in the ACLF liver tissues, which were effectively reversed by WYJD. Mechanistically, WYJD upregulated SDH activity and expression of its catalytic subunits SDHA/B, facilitating succinate-to-fumarate conversion and reducing succinate levels, thereby suppressing downstream hypoxia-inducible factor-1α expression. In addition, WYJD improved mitochondrial ultrastructure, restored ATP content, and reduced CD68+ macrophage infiltration in liver. These beneficial effects were partially abolished by SDH inhibition.

CONCLUSION

WYJD ameliorated ACLF by acting partly through SDH to clear accumulated succinate and suppress hypoxia-inducible factor-1α-mediated inflammation, suggesting succinate metabolism as a potential therapeutic target.

Core Tip: This study demonstrated that Wenyang Jiedu Huayu Formula (WYJD) ameliorated acute-on-chronic liver failure by targeting succinate metabolism. WYJD acts partly through succinate dehydrogenase to clear accumulated succinate and suppress hypoxia-inducible factor-1α signaling, thereby correcting energy metabolic disturbances and attenuating macrophage-mediated inflammation. These findings suggested that succinate metabolism can be a potential therapeutic target in acute-on-chronic liver failure, and the study provided mechanistic insights supporting the clinical application of WYJD from a metabolic-immune perspective.
