Abstract

Background: Diabetic liver injury (DLI) is a common complication of diabetes mellitus (DM), which seriously endangers the health of diabetic patients. Puerarin, the main active component of Pueraria lobata, has shown positive effects in lowering blood glucose and lipids, resisting oxidative stress, and protecting the liver. However, the mechanism of protective effect of Puerarin on DLI remains unclear.

Methods: Various databases were used to screen for targets of Puerarin, ferroptosis and DLI. Protein-protein interaction (PPI) network and Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analysis were used to predict key targets and pathways. Molecular docking was used to predict the interactions between Puerarin and core targets. KK/Upj-Ay/J (KKAy) mice and high glucose (HG)-induced AML12 cells were used to study the protective effect of Puerarin on DLI. The molecular mechanisms by which Puerarin acts were further verified by in vivo and in vitro experiments.

Results: KEGG analysis indicated that the JAK/STAT pathway might be related to the anti-DLI effect of Puerarin. Molecular docking revealed that Puerarin has good affinity for JAK2 and STAT3. In vivo, Puerarin (80 mg/kg) reduced body weight, blood glucose, blood lipids and liver function in KKAy mice fed a high-sugar, high-fat diet. Puerarin also ameliorated hepatic pathological changes and inflammatory responses, and attenuated oxidative stress and iron overload in KKAy mice. Western blotting results showed that Puerarin could regulate the expression of proteins related to JAK2/STAT3 pathway and ferroptosis pathway. In vitro, Puerarin (25, 50, 100 μM) increased cell viability and decreased steatosis and liver function indexes in AML12 cells induced by HG (30 mm) to varying degrees. More importantly, AG490 blocker experiments showed that the regulation of ferroptosis process by Puerarin was dependent on the JAK2/STAT3 pathway.

Conclusion: In conclusion, this study revealed Puerarin may regulate the ferroptosis process by inhibiting the JAK2/STAT3 pathway for the treatment of DLI.
