Hyperuricemia (HUA) is a metabolic disorder characterized by abnormal purine metabolism and/or reduced uric acid (UA) excretion. Chicory ( L.), recognized in Traditional Chinese Medicine, is noted for its anti-HUA effects, particularly in enhancing intestinal UA excretion, though the underlying mechanisms remain unclear. Studies indicate that disruptions in gut microbiota and its metabolites are associated with HUA, and chicory has been demonstrated to ameliorate gut microbiota dysbiosis. Among gut microbiota-derived metabolites, butyrate, a short-chain fatty acid, plays a crucial role in gut functions and is linked to HUA. Therefore, butyrate may be pivotal in elucidating the mechanism by which chicory promotes intestinal UA excretion. This study aims to investigate whether chicory facilitates intestinal UA excretion through gut microbiota-derived butyrate and to elucidate the underlying mechanism. We employed an integrated methodology combining network biology with the NHANES database analysis to explore the pathological relationship between butyrate and HUA. Our findings were subsequently validated through animal experiments. We administered chicory to rats with HUA to ascertain whether butyrate serves as the key gut microbiota metabolite through which chicory promotes intestinal UA excretion. Furthermore, we utilized western blotting to assess the expression of core targets within the PPARγ-ABCG2 pathway associated with butyrate under conditions where animals received butyrate supplements and PPARγ agonists separately. The network biology indicates that butyrate is a crucial short-chain fatty acid influencing HUA. Analyses of NHANES data and animal experiments further confirm a significant negative correlation between butyrate and serum uric acid (SUA) levels. HUA rats exhibited intestinal barrier damage, impaired intestinal UA excretion, reduced butyrate levels, and decreased expression of PPARγ and ABCG2 proteins. Intervention with chicory in HUA rats repaired intestinal barrier damage, enhanced intestinal UA excretion, and increased both butyrate levels and the expression of PPARγ and ABCG2 proteins. Similarly, interventions with butyrate supplements or PPARγ agonists in HUA rats effectively promoted intestinal UA excretion and increased the expression of PPARγ and ABCG2 proteins. This study demonstrates that butyrate is a key metabolite produced by gut microbiota, through which chicory regulates gut microbiota to enhance intestinal UA excretion. The underlying mechanism involves the activation of the PPARγ-ABCG2 pathway, which is facilitated by elevated butyrate levels in the intestine.
