Metabolomics Based Exploration of the Mechanism of Action of Tripterygium Glycosides in Diabetic Kidney Disease

Tripterygium glycosides (TGs), the primary active components of Tripterygium wilfordii, have demonstrated therapeutic efficacy in treating diabetic kidney disease (DKD). However, the precise mechanisms underlying their action remain elusive, limiting the full realization of their medicinal potential. This study employed serum metabolomics based on liquid chromatography–mass spectrometry (LC-MS) analysis to elucidate the mechanisms by which TGs combat DKD. We evaluated the protective effects of TGs on DKD following treatment. Serum samples were collected before and after treatment, and their metabolic profiles were analyzed using LC-MS. Our metabolomics analysis revealed that TGs significantly modulated the hedgehog signaling pathway, a key metabolic pathway implicated in DKD pathogenesis. This study represents the first comprehensive investigation of the metabolic pathways regulated by TGs in the context of DKD using a metabolomics approach. Our findings provide a robust theoretical foundation for the more effective utilization and potential combination therapies involving TGs in the management of DKD. These insights pave the way for further research and development of targeted therapeutic strategies for this challenging condition.
