Network pharmacology analysis reveals that coumestrol targets ZYX to inhibit ferroptosis and alleviate acute pancreatitis

Abstract

Aim

The therapeutic effect of CMS on acute pancreatitis (AP) and the mechanism of targeting Zyxin (ZYX) to regulate ferroptosis in acinar cells.

Methods

To assess the therapeutic effects of CMS in AP, we established caerulein-induced AP and caerulein plus LPS-induced SAP mouse models. Subsequently, weighted gene co-expression network analysis (WGCNA) and network pharmacology analysis were used to investigate the mechanism and target of CMS in the treatment of AP. Molecular docking and cell biology techniques were used to explore the molecular mechanisms by which CMS mitigated ferroptosis in AP animal and cell models.

Results

CMS could alleviate the pathological damage of AP and SAP, inhibit ferroptosis and reduce inflammatory response. ZYX was an important target for CMS in the treatment of AP, and CMS could specifically bind to ZYX, down-regulate ZYX expression, and reduce TGF-β/SMAD pathway activity, thereby inhibiting acinar cell ferroptosis and improving pancreatic injury in AP. And we found that ZYX overexpression counteracted the inhibitory effects of CMS on TGF-β/Smad signaling and ferroptosis processes.

Conclusion

These results suggested that coumestrol targeting ZYX regulated the TGF-β/SMAD pathway, inhibited ferroptosis in acinar cells, and alleviated AP. Our research provided new drugs and targets for the treatment of AP.
